• Visual C++ Prefast and LoadString weirdness

  Hello everyone, I am trying to compile my old C++ code with Whidbey Beta 2 and prefast turned on (/analysis for static code analysis, turn on "Enable code analysis for C/C++" in Advanced settings of C/C++ configuration properties).

I've boiled it down to two small functions foo() and bar() that should behave identical but the first one gives a prefast warning(C6386: buffer overrun: accessing 'argument 3', the writable size is '1*0' bytes, but '1' bytes may be written...). void foo() {     int nBuffer = 1;     LPTSTR szText = (LPTSTR) ...Show All

• SQL Server Stuck between "Failed to generate user instance" and "An attempt to attach...failed"

  I wrote an application using Visual Studio 2005 beta 2 which uses a SQL Express .mdf file, included in the project, for the database.  After installing Visual Studio 2005 RC and the SQL Express that comes with it (I followed all of the uninstall instructions first) I can no longer add a SQL Express database to any of my projects, nor can I open the SQL Express database in my original project.  When I try either of these tasks, I get the "Failed to generate user instance of SQL Server due to a failure in starting the process for the user instance.  The connection will be closed."  I read the thread which dealt with this er ...Show All

• Visual C# Can FileSystemWatcher raise different events depending on file path?

  I have a FileSystemWatcher that watches a directory. This has 3 sub-directories. I was thinking of just making 3 different FileSystemWatcher objects to watch each directory individualy, because when a file is created in one of these directories I need different events raised. For directory A, I want MethodA called, and dir B I need MethodB called and Method C called when a new file is placed in Directory C. Can one FileSystemWatcher call different methods depending on the path of the created file I use this : watcher.Created += new FileSystemEventHandler (FileCreated); to call my FileCreated() method, any ideas Thanks... ...Show All

• SQL Server Task Expression Evalutation Time

  I have designed a package whose first step initializes several variables .  Other steps in the package have expressions based on those variables. Example Expression for MyTask:    PropertyName = "Disable"    Expression = "@DoMyTask" Given this example MyTask will be enabled/disabled solely based on the value of @DoMyTask at the time the package execution begins.  Changing the value of @DoMyTask prior to the normal execution of MyTask has no effect . My conclusion is that the expression is not being evaluated late enough.  Any help   DarrenSQ ...Show All
