Figure 10-4: At the end of the editing phase, the updated DataSet object is resaved as a DiffGram and the pending changes are displayed. The child form allows you to set errors and enter any type of changes. When the form is dismissed, the main application automatically saves the bound DataSet object back to a DiffGram and refreshes the user interface. As a result, you can easily test the DiffGram and view how the output varies after data changes. A nice feature of the DiffGram Viewer application is that it lets you toggle the DiffGram view between plain text and XML. The XML view is provided by Internet Explorer, as shown in Figure 10-5. vb.net code to extract text from pdf: Extract Text from PDF in C# (100% .

CrashFinder and your debugger rely on symbol tables and a symbol engine to read them. If the format of the symbol table changes or if you forget to save the Program Database (PDB) files, you're completely out of luck. Forgetting to save the PDB files is your fault, but you have no control over symbol table formats. They change frequently.

Microsoft changed the symbol table format and does so on a regular basis. MAP files are your only savior at that time. Even though you, as a developer, might be up to Window Server 2008 with Visual Studio .NET 2007 Service Pack 6 in five years, I can assure you that you'll still have customers who will be running the software you released back in 2003. When they call you in alarm and give you a crash address, you could spend the next two days trying to find the Visual Studio .NET CDs so that you can read your saved PDB files. Or if you have the MAP files, you can find the problem in five minutes. MAP File Contents Listing 12-1 shows an example MAP file. The top part of the MAP file contains the module name, the timestamp indicating when LINK.EXE linked the module, and the preferred load address.

The GetChanges method also has a few overloads that let you control the type of changes you are interested in For example, the following code prepares a DiffGram containing only the rows that have been inserted: DataSet dsChanges = dsGetChanges(DataRowStateAdded); dsChangesWriteXml(writer, XmlWriteModeDiffGram); Loading a DataSet Object from a DiffGram When you try to build a DataSet object from an XML DiffGram, you must first ensure that the target DataSet object has a schema that is compatible with the data in the DiffGram 374. 12 1 3 0390201c 03902020 03902024 In no case does the ReadXml method the only DataSet method that can load a DiffGram infer the schema or extend with new elements an existing schema ReadXml works by merging the rows read from the DiffGram with existing rows in the DataSet object The DiffGram row identifier (the diffgr:id attribute) is used to pair DiffGram and DataSet object rows Any incompatibility between the current schema of the DataSet object and the data in the DiffGram throws an exception and causes the merge operation to fail As a result, you can't load a DiffGram into an empty, newly created DataSet object You can create the target DataSet object simply by cloning an existing object that you know has the correct schema Or, more realistically, you might want to read the schema from an external support using the ReadXmlSchema method. 0002:0000007c _C@_0CE@EBHAJKCA@Whoops 0 5a 5crash 5is 5about 5to 5 occu@ 0390207c 0002:000000a0 _C@_0CD@OILENIKO@Hello 5from 5InternalStaticFunctio@ 039020a0 MapDLL.obj 0002:000000c4 _C@_0BM@DFMPKPOD@Hello 5from 5MapDLLFunction $CB 6 $ AA@ 039020c4 0002:000000e0 __load_config_used MSVCRT:loadcfg .obj 0002:00000190 defined> ___safe_se_handler_table 03902190 MapDLL.obj 039020e0 <linker03902194 03902198 0390219c 039021a0 039021a4 039021b8 03903000 03903004 03903008 0390300c 03903010 03903018 0390301c 03903020 03903024 440 <common> <common> <common> <common> MapDLL.obj 12 12 1 0002:00000194 ___rtc_iaa MSVCRT:initsec t.obj 0002:00000198 ___rtc_izz MSVCRT:initsec t.obj 0002:0000019c ___rtc_taa MSVCRT:initsec t.obj 0002:000001a0 ___rtc_tzz MSVCRT:initsec t.obj 0002:000001a4 MSVCRT:MSVCR7 1.dll 0002:000001b8 MSVCRT:MSVCR71 .dll __IMPORT_DESCRIPTOR_MSVCR71 __NULL_IMPORT_DESCRIPTOR The following code snippet shows how to create a DiffGram and its schema in distinct files: // Prepare the output stream for the DiffGram StreamWriter diffStrm = new StreamWriter(diffgramFile);
