• Davester Redistribution of C runtime libraries without MSI installation

  Hi guys, I'm trying to get an installer of our product working.  I've finally gotten it compiling and running under VS2005.  For various technical and political reasons, I have to use NSIS as our installation technique. This is where the problem begins.  I can't quite see how to redistribute the relevant CRT libraries.  I've been round and round in circles following the MSDN information, and various blog postings (e.g. http:/ ...Show All

• genocide77 Intellisense updates very slowly, and blocks builds - what can I do?

  I'm working on a fairly large program, and the NCB file quickly rises to 90MB, especially after edit-and-continue. Intellisense keeps firing up and showing "Updating intellisense" in the status bar, for several minutes at a time - but much worse than that, it appears to be (read-)locking files that a build needs, so if I use edit-and-continue, then stop debugging, the build that fires off collides with Intellisense and fails, and ma ...Show All

• Dijkstra30 .

  . . . Rob: in the .NET world the identity of a type includes the assembly in which it is defined. Therefore in your example above there are two enum types named MyNamespace::MyEnum: the first is from assembly dll2 and the second is from dlltest and as far as the CLR is concerned these are two completely different types. The correct solution is ...Show All

• Chris B Leu MCP why are the NCB files so large in VC++ 2005?

  Hello, I am really puzzled about the NCB store in Visual Studio 2005. I understand that some improvements have been made to the IntelliSense, but the size of NCB files in really huge. I have noticed that on average a NCB file is 10 times largers than the file for the same project under VS 6 and 7.x. For instance, an NCB file of 50KB under VS 2003 now has 500-600 KB, a 200 KB NCB under VS 2003 now has about 2 MB. And NCB files that used ...Show All
