Structured Storage signature This integer field contains the starting sector number for the mini FAT Provides the set of values by which a binary search tree can be enumerated. Action to implement when transaction support - sector has to be written to the underlying stream (see specs). Ad-hoc Heap Friendly sector collection to avoid using large array that may create some problem to GC collection (see http://www.simple-talk.com/dotnet/.net-framework/the-dangers-of-the-large-object-heap/ ) Abstract base class for Structured Storage entities. const String STORAGE_NAME = "report.xls"; CompoundFile cf = new CompoundFile(STORAGE_NAME); FileStream output = new FileStream("LogEntries.txt", FileMode.Create); TextWriter tw = new StreamWriter(output); // CFItem represents both storage and stream items VisitedEntryAction va = delegate(CFItem item) { tw.WriteLine(item.Name); }; cf.RootStorage.VisitEntries(va, true); tw.Close(); Get entity name Size in bytes of the item. It has a valid value only if entity is a stream, otherwise it is setted to zero. Return true if item is Storage This check doesn't use reflection or runtime type information and doesn't suffer related performance penalties. Return true if item is a Stream This check doesn't use reflection or runtime type information and doesn't suffer related performance penalties. Return true if item is the Root Storage This check doesn't use reflection or runtime type information and doesn't suffer related performance penalties. Get/Set the Creation Date of the current item Get/Set the Modify Date of the current item Get/Set Object class Guid for Root and Storage entries. Represents a collection of Node<T> instances. The type of data held in the Node instances referenced by this class. Searches the NodeList for a Node containing a particular value. The value to search for. The Node in the NodeList, if it exists; null otherwise. Represents a binary search tree. A binary search tree is a binary tree whose nodes are arranged such that for any given node k, all nodes in k's left subtree have a value less than k, and all nodes in k's right subtree have a value greater than k. The type of data stored in the binary tree nodes. Removes the contents of the BST Copies the contents of the BST to an appropriately-sized array of type T, using the Inorder traversal method. Copies the contents of the BST to an appropriately-sized array of type T, using a specified traversal method. Adds a new value to the BST. The data to insert into the BST. Adding a value already in the BST has no effect; that is, the SkipList is not altered, the Add() method simply exits. Returns a Boolean, indicating if a specified value is contained within the BST. The data to search for. True if data is found in the BST; false otherwise. Returns a Boolean, indicating if a specified value is contained within the BST. The data to search for. True if data is found in the BST; false otherwise. Attempts to remove the specified data element from the BST. The data to remove from the BST. True if the element is found in the tree, and removed; false if the element is not found in the tree. Enumerates the BST's contents using inorder traversal. An enumerator that provides inorder access to the BST's elements. Enumerates the BST's contents using a specified traversal method. The type of traversal to perform. An enumerator that provides access to the BST's elements using a specified traversal technique. Provides enumeration through the BST using preorder traversal. Provides enumeration through the BST using inorder traversal. Provides enumeration through the BST using postorder traversal. Returns the number of elements in the BST. Binary File Format Version. Sector size is 512 byte for version 3, 4096 for version 4 Compound file version 3 - The default and most common version available. Sector size 512 bytes, 2GB max file size. Compound file version 4 - Sector size is 4096 bytes. Using this version could bring some compatibility problem with existing applications. Update mode of the compound file. Default is ReadOnly. ReadOnly update mode prevents overwriting of the opened file. Data changes are allowed but they have to be persisted on a different file when required. Update mode allows subsequent data changing operations to be persisted directly on the opened file or stream using the Commit method when required. Warning: this option may cause existing data loss if misused. Standard Microsoft© Compound File implementation. It is also known as OLE/COM structured storage and contains a hierarchy of storage and stream objects providing efficent storage of multiple kinds of documents in a single file. Version 3 and 4 of specifications are supported. Number of DIFAT entries in the header Sector ID Size (int) Initial capacity of the flushing queue used to optimize commit writing operations Maximum size of the flushing buffer used to optimize commit writing operations Returns the size of standard sectors switching on CFS version (3 or 4) Standard sector size Number of FAT entries in a DIFAT Sector Sectors ID entries in a FAT Sector Flag for sector recycling. Flag for unallocated sector zeroing out. CompoundFile header Compound underlying stream. Null when new CF has been created. Create a blank, version 3 compound file. Sector recycle is turned off to achieve the best reading/writing performance in most common scenarios. byte[] b = new byte[10000]; for (int i = 0; i < 10000; i++) { b[i % 120] = (byte)i; } CompoundFile cf = new CompoundFile(); CFStream myStream = cf.RootStorage.AddStream("MyStream"); Assert.IsNotNull(myStream); myStream.SetData(b); cf.Save("MyCompoundFile.cfs"); cf.Close(); Create a new, blank, compound file. Use a specific Compound File Version to set 512 or 4096 bytes sectors If true, recycle unused sectors If true, unallocated sectors will be overwritten with zeros byte[] b = new byte[10000]; for (int i = 0; i < 10000; i++) { b[i % 120] = (byte)i; } CompoundFile cf = new CompoundFile(CFSVersion.Ver_4, true, true); CFStream myStream = cf.RootStorage.AddStream("MyStream"); Assert.IsNotNull(myStream); myStream.SetData(b); cf.Save("MyCompoundFile.cfs"); cf.Close(); Sector recycling reduces data writing performances but avoids space wasting in scenarios with frequently data manipulation of the same streams. The new compound file is open in Update mode. Load an existing compound file. Compound file to read from //A xls file should have a Workbook stream String filename = "report.xls"; CompoundFile cf = new CompoundFile(filename); CFStream foundStream = cf.RootStorage.GetStream("Workbook"); byte[] temp = foundStream.GetData(); Assert.IsNotNull(temp); cf.Close(); File will be open in read-only mode: it has to be saved with a different filename. A wrapping implementation has to be provided in order to remove/substitute an existing file. Version will be automatically recognized from the file.

Distribution Obligations. 3.1. Application of License. The Modifications which You create or to which You contribute are governed by the terms of this License, including without limitation Section 2.2. The Source Code version of Covered Code may be distributed only under the terms of this License or a future version of this License released under Section 6.1, and You must include a copy of this License with every copy of the Source Code You distribute. You may not offer or impose any terms on any Source Code version that alters or restricts the applicable version of this License or the recipients' rights hereunder. However, You may include an additional document offering the additional rights described in Section 3.5. 3.2. Availability of Source Code. Any Modification which You create or to which You contribute must be made available in Source Code form under the terms of this License either on the same media as an Executable version or via an accepted Electronic Distribution Mechanism to anyone to whom you made an Executable version available; and if made available via Electronic Distribution Mechanism, must remain available for at least twelve (12) months after the date it initially became available, or at least six (6) months after a subsequent version of that particular Modification has been made available to such recipients. You are responsible for ensuring that the Source Code version remains available even if the Electronic Distribution Mechanism is maintained by a third party. 3.3. Description of Modifications. You must cause all Covered Code to which You contribute to contain a file documenting the changes You made to create that Covered Code and the date of any change. You must include a prominent statement that the Modification is derived, directly or indirectly, from Original Code provided by the Initial Developer and including the name of the Initial Developer in (a) the Source Code, and (b) in any notice in an Executable version or related documentation in which You describe the origin or ownership of the Covered Code. 3.4.

If Contributor obtains such knowledge after the Modification is made available as described in Section 3.2, Contributor shall promptly modify the LEGAL file in all copies Contributor makes available thereafter and shall take other steps (such as notifying appropriate mailing lists or newsgroups) reasonably calculated to inform those who received the Covered Code that new knowledge has been obtained. (b) Contributor APIs. If Contributor's Modifications include an application programming interface and Contributor has knowledge of patent licenses which are reasonably necessary to implement that API, Contributor must also include this information in the LEGAL file. (c) Representations. Contributor represents that, except as disclosed pursuant to Section 3.4(a) above, Contributor believes that Contributor's Modifications are Contributor's original creation(s) and/or Contributor has sufficient rights to grant the rights conveyed by this License. 3.5. Required Notices. You must duplicate the notice in Exhibit A in each file of the Source Code. If it is not possible to put such notice in a particular Source Code file due to its structure, then You must include such notice in a location (such as a relevant directory) where a user would be likely to look for such a notice. If You created one or more Modification(s) You may add your name as a Contributor to the notice described in Exhibit A. You must also duplicate this License in any documentation for the Source Code where You describe recipients' rights or ownership rights relating to Covered Code. You may choose to offer, and to charge a fee for, warranty, support, indemnity or liability obligations to one or more recipients of Covered Code. However, You may do so only on Your own behalf, and not on behalf of the Initial Developer or any Contributor. You must make it absolutely clear than any such warranty, support, indemnity or liability obligation is offered by You alone, and You hereby agree to indemnify the Initial Developer and every Contributor for any liability incurred by the Initial Developer or such Contributor as a result of warranty, support, indemnity or liability terms You offer. 3.6. Distribution of Executable Versions. You may distribute Covered Code in Executable form only if the requirements of Section 3.1-3.5 have been met for that Covered Code, and if You include a notice stating that the Source Code version of the Covered Code is available under the terms of this License, including a description of how and where You have fulfilled the obligations of Section 3.2. The notice must be conspicuously included in any notice in an Executable version, related documentation or collateral in which You describe recipients' rights relating to the Covered Code. You may distribute the Executable version of Covered Code or ownership rights under a license of Your choice, which may contain terms different from this License, provided that You are in compliance with the terms of this License and that the license for the Executable version does not attempt to limit or alter the recipient's rights in the Source Code version from the rights set forth in this License. If You distribute the Executable version under a different license You must make it absolutely clear that any terms which differ from this License are offered by You alone, not by the Initial Developer or any Contributor. You hereby agree to indemnify the Initial Developer and every Contributor for any liability incurred by the Initial Developer or such Contributor as a result of any such terms You offer. 3.7. Larger Works. You may create a Larger Work by combining Covered Code with other code not governed by the terms of this License and distribute the Larger Work as a single product. In such a case, You must make sure the requirements of this License are fulfilled for the Covered Code. 4. Inability to Comply Due to Statute or Regulation. If it is impossible for You to comply with any of the terms of this License with respect to some or all of the Covered Code due to statute, judicial order, or regulation then You must: (a) comply with the terms of this License to the maximum extent possible; and (b) describe the limitations and the code they affect. Such description must be included in the LEGAL file described in Section 3.4 and must be included with all distributions of the Source Code. Except to the extent prohibited by statute or regulation, such description must be sufficiently detailed for a recipient of ordinary skill to be able to understand it. 5. Application of this License. This License applies to code to which the Initial Developer has attached the notice in Exhibit A and to related Covered Code. 6. Versions of the License. 6.1. New Versions. Netscape Communications Corporation ("Netscape") may publish revised and/or new versions of the License from time to time. Each version will be given a distinguishing version number. 6.2.

THIS DISCLAIMER OF WARRANTY CONSTITUTES AN ESSENTIAL PART OF THIS LICENSE. NO USE OF ANY COVERED CODE IS AUTHORIZED HEREUNDER EXCEPT UNDER THIS DISCLAIMER. 8. TERMINATION. 8.1. This License and the rights granted hereunder will terminate automatically if You fail to comply with terms herein and fail to cure such breach within 30 days of becoming aware of the breach. All sublicenses to the Covered Code which are properly granted shall survive any termination of this License. Provisions which, by their nature, must remain in effect beyond the termination of this License shall survive. 8.2. If You initiate litigation by asserting a patent infringement claim (excluding declatory judgment actions) against Initial Developer or a Contributor (the Initial Developer or Contributor against whom You file such action is referred to as "Participant") alleging that: (a) such Participant's Contributor Version directly or indirectly infringes any patent, then any and all rights granted by such Participant to You under Sections 2.1 and/or 2.2 of this License shall, upon 60 days notice from Participant terminate prospectively, unless if within 60 days after receipt of notice You either: (i) agree in writing to pay Participant a mutually agreeable reasonable royalty for Your past and future use of Modifications made by such Participant, or (ii) withdraw Your litigation claim with respect to the Contributor Version against such Participant. If within 60 days of notice, a reasonable royalty and payment arrangement are not mutually agreed upon in writing by the parties or the litigation claim is not withdrawn, the rights granted by Participant to You under Sections 2.1 and/or 2.2 automatically terminate at the expiration of the 60 day notice period specified above. (b) any software, hardware, or device, other than such Participant's Contributor Version, directly or indirectly infringes any patent, then any rights granted to You by such Participant under Sections 2.1(b) and 2.2(b) are revoked effective as of the date You first made, used, sold, distributed, or had made, Modifications made by that Participant. 8.3. If You assert a patent infringement claim against Participant alleging that such Participant's Contributor Version directly or indirectly infringes any patent where such claim is resolved (such as by license or settlement) prior to the initiation of patent infringement litigation, then the reasonable value of the licenses granted by such Participant under Sections 2.1 or 2.2 shall be taken into account in determining the amount or value of any payment or license. 8.4. In the event of termination under Sections 8.1 or 8.2 above, all end user license agreements (excluding distributors and resellers) which have been validly granted by You or any distributor hereunder prior to termination shall survive termination. 9.

Sector size is 512 byte for version 3, 4096 for version 4 Compound file version 3 - The default and most common version available. Sector size 512 bytes, 2GB max file size. Compound file version 4 - Sector size is 4096 bytes. Using this version could bring some compatibility problem with existing applications. Update mode of the compound file. Default is ReadOnly. ReadOnly update mode prevents overwriting of the opened file. Data changes are allowed but they have to be persisted on a different file when required. Update mode allows subsequent data changing operations to be persisted directly on the opened file or stream using the Commit method when required. Warning: this option may cause existing data loss if misused. Standard Microsoft© Compound File implementation.

Opening Tests ------------- To open a test, open a test project or a test metadata file (a file with extension .vsmdi) that contains the definition of the test. You can find test projects and metadata files in Solution Explorer. Viewing Tests ------------- To see which tests are available to you, open the Test View window. Or, if you have installed Team Edition for Software Testers, you can also open the Test List Editor window to view tests. To open the Test View window, click the Test menu, point to Windows, and then click Test View. To open the Test List Editor window (if you have installed Team Edition for Software Testers), click Test, point to Windows, and then click Test List Editor. Running Tests ------------- You can run tests from the Test View window and the Test List Editor window. See Viewing Tests to learn how to open these windows. To run one or more tests displayed in the Test View window, first select the tests in that window; to select multiple tests, hold either the Shift or CTRL key while clicking tests. Then click the Run Tests button in the Test View window toolbar. If you have installed Visual Studio Team Edition for Software Testers, you can also use the Test List Editor window to run tests. To run tests in Test List Editor, select the check box next to each test that you want to run. Then click the Run Tests button in the Test List Editor window toolbar. Viewing Test Results -------------------- When you run a test or a series of tests, the results of the test run will be shown in the Test Results window. Each individual test in the run is shown on a separate line so that you can see its status. The window contains an embedded status bar in the top half of the window that provides you with summary details of the complete test run. To see more detailed results for a particular test result, double-click it in the Test Results window. This opens a window that provides more information about the particular test result, such as any specific error messages returned by the test. Changing the way that tests are run ----------------------------------- Each time you run one or more tests, a collection of settings is used to determine how those tests are run. These settings are contained in a “test run configuration” file. Here is a partial list of the changes you can make with a test run configuration file: - Change the naming scheme for each test run. - Change the test controller that the tests are run on so that you can run tests remotely. - Gather code coverage data for the code being tested so that you can see which lines of code are covered by your tests. - Enable and disable test deployment. - Specify additional files to deploy before tests are run. - Select a different host, ASP.NET, for running ASP.NET unit tests. - Select a different host, the smart device test host, for running smart device unit tests. - Set various properties for the test agents that run your tests. - Run custom scripts at the start and end of each test run so that you can set up the test environment exactly as required each time tests are run. - Set time limits for tests and test runs. - Set the browser mix and the number of times to repeat Web tests in the test run. By default, a test run configuration file is created whenever you create a new test project. You make changes to this file by double-clicking it in Solution Explorer and then changing its settings. (Test run configuration files have the extension .testrunconfig.) A solution can contain multiple test run configuration files. Only one of those files, known as the “Active” test run configuration file, is used to determine the settings that are currently used for test runs. You select the active test run configuration by clicking Select Active Test Run Configuration on the Test menu. ------------------------------------------------------------------------------- Test Types ---------- Using Visual Studio Team Edition for Software Testers, you can create a number of different test types: Unit test: Use a unit test to create a programmatic test in C++, Visual C# or Visual Basic that exercises source code. A unit test calls the methods of a class, passing suitable parameters, and verifies that the returned value is what you expect. There are three specialized variants of unit tests: - Data-driven unit tests are created when you configure a unit test to be called repeatedly for each row of a data source. The data from each row is used by the unit test as input data. - ASP.NET unit tests are unit tests that exercise code in an ASP.NET Web application. - Smart device unit tests are unit tests that are deployed to a smart device or emulator and then executed by the smart device test host. Web Test: Web tests consist of an ordered series of HTTP requests that you record in a browser session using Microsoft Internet Explorer. You can have the test report specific details about the pages or sites it requests, such as whether a particular page contains a specified string. Load Test: You use a load test to encapsulate non-manual tests, such as unit, Web, and generic tests, and then run them simultaneously by using virtual users. Running these tests under load generates test results, including performance and other counters, in tables and in graphs. Generic test: A generic test is an existing program wrapped to function as a test in Visual Studio. The following are examples of tests or programs that you can turn into generic tests: - An existing test that uses process exit codes to communicate whether the test passed or failed. 0 indicates passing and any other value indicates a failure. - A general program to obtain specific functionality during a test scenario. - A test or program that uses a special XML file (called a “summary results file”), to communicate detailed results. Manual test: The manual test type is used when the test tasks are to be completed by a test engineer as opposed to an automated script. Ordered test: Use an ordered test to execute a set of tests in an order you specify. ------------------------------------------------------------------------------- openmcdf-1.5.4/src/OLECFSTest/CFSStreamTest.cs0000644000175000017500000007201712042056202020546 0ustar mathieumathieuusing System;
