    - by roygbiv
    I've been told that using GDI+ from ASP.NET is dangerous and undefined. Is that because there is no guarantee of a Device Context? Can someone explain? What are some of the alternatives? Here is the source: http://msdn.microsoft.com/en-us/library/system.drawing.aspx

  • Where are Silverlight assemblies stored when a xap file is run?

    - by ForeverDebugging
    We currently have a XAP file which contains Foo.dll, and another XAP file (with a completely different name) which contains an updated version Foo.dll (but the same version number). When we run the second XAP file, it looks as though the Silverlight runtime on the client, is picking up the old version of Foo.dll from the first XAP file. Anyone know where the Silverlight runtime unzips the xap file before running its content? Or if the runtime executes on a single app domain which could explain these errors?

P.S.: It would be great, if you may also check for any syntax errors as I'm totally new to MSSQL and stored procedures.

  • What is the correct way to create a single instance application?

    - by Nidonocu
    Using C# and WPF under .net (rather than WindowsForms or console), what is the correct way to create an application that can only be run as a single instance? I know it has something to do with some mythical thing called a mutex, rarely can I find someone that bothers to stop and explain what one of these are. The code needs to also inform the already running instance that the user tried to start a second one, and maybe also pass any command line arguments if any existed.
