• .NET Development Problem with XsltCompiledTransform for large data

  Hello! I was wondering if anybody could help me to solve my problem: I call a stored proc in SQL server with ExecuteXmlReader, then load my xslt stylesheet into XsltCompiledTransform, create a output file stream.  and call Transform method. The problem is that it works fine for small resultsets. Fot large resultsets ( ~1Mil Rows ) the process in Task Manager increases memory allocation and slows down extremely. I hoped that as I used xmlreader and streamwriter there should not be a big memory problem like with the case of DataSet instead of XmlWriter. Alas, this is not true. Could anybody give any suggestions on this Thanks in advance ...Show All

• Software Development for Windows Vista Windows Workflow Foundation from a business perspective

  As a developer I am really enthousiastic about the new Windows Vista related technologies, and especially Windows Workflow Foundation. Being a developer, I have lots of stuff to read about this subject. There are many good-quality articles, whitepapers, webcasts and forums such as this one to help me get started. The problem is, however, that if I want to convince the management team of my company that WWF and WCF are the way to go (which I think it is), I can't seem to find (really) good information from a business perspective. All presentations directly dive into code on slide 3 or 5 or so, and most articles I found are too developer ...Show All

• Windows Forms programmatically find a row in a DataGridView and select it

  Hi There, I've got a DataView populated with data from a Table. The Table contains a PrimaryKey. With this DataView I populate a DataGridView and show all Columns except the PrimaryKey Column. What I now want is to find a row due to a given PrimaryKey Value. How can I do this without to iterate thorugh all rows and check the PrimaryKey from each DataRowView Thanks in advance... Greet Markus thank yiou. Now I understand your design choices. I guess you must either be using the datagrid in read only mode or have some other GUI for use to start editing.

• SQL Server Secure .NET 1.1 application from users

  Hi all. I am developing an distributed VB.NET 1.1 application with a TripleDES capable socket layer for communication with my server app. I need to secure the distributed app from the users within the organization I am developing it for (a franchise). I do not wish to store any encryption keys in the source code as these would be obvious to any seasoned hacker through decompilation of my binaries (even with obfuscation). I have decided to use the windows DPAPI (under machine storage mode) to secure manually entered (at installation) encryption layer keys in the registry. The salt values for this DPAPI mode also need to be secured, ...Show All

• Visual C++ Changed the COM signatures....using ildasm.....

  Hi, I have a .exe COM which I used in .NET but some signatures got changed....so I opened it with ildasm and changed the signatures so that it should return something from the function....This is the error I'm getting now.... The runtime has encountered a fatal error. The address of the error was at 0x79e8aff6, on thread 0xb4. The error code is 0xc0000005. This error may be a bug in the CLR or in the unsafe or non-verifiable portions of user code. Common sources of this bug include user marshaling errors for COM-interop or PInvoke, which may corrupt the stack. Any Ideas.... Thanks, Harsimrat ...Show All

• Windows Forms Windows Forms application closes unexpectedly

  Hi, we have a quite large Windows Forms application (one small executable and about 30 assemblies). On several client PCs (Windows XP SP2) the application suddenly disappears (like a crash but without an exception). We register a ThreadExceptionHandler with the application instance to catch otherwise not caught exceptions, which normally works. But in the case of the above issue the application seems to close without calling the Form.OnClosing handle; we always ask the user if the application may be closed, but in the case of the problem no message box is displayed. In our internal logs i see several garbage collector cleanup for some ...Show All
