Would copying source and assembly files to another directory, cl /clr <files> from the sdk 3.0 command prompt suffice The one I tried did not readily reveal it was using 3.0 unless I added /Zi to the command line within the pdb, is there any other way to know for certain it is using 3.0 instead of 2.0 Thanks. ...Show All

• Rafet Problem loading dll created by VisC 2005

  Hi, I converted a C++ project from VS .NET 7.1 to VS .NET 8. The project uses old fopen methods and similar. Under 7.1 the project compiles and runs, but under 8, I am unable to run. First, when running the application, it complains about missing msvcr80.dll. Then, when I locate it (somewhere) on the computer, I get the error that the application tried to load the dll in an illegal manner. When searching for info on this, I stumble into manifests, and I see that the manifest should contain some lines about the msvcr80.dll, version etc. But my manifest file is empty. It only contains this information: < xml version="1.0" encoding="UTF-8" standalone="yes" > <assembly xmlns="urn:schemas-microsoft-com:asm.v1" manif ...Show All

• jgd12345 linkage error when using _DEBUG with multi-threaded dll (as runtime libraries)

  Hi, We work on a project and would like to be able to use some dll's in release and some in debug. There for and since we use stl we wanted to change our runtime libraries (for the debug build) to use the "multi-threaded dll" and not the "multi-threaded debug dll". doing so created a link error: error LNK2001: unresolved external symbol __imp___CrtDbgReportW as I understand things this shouldn't have happend (I guess it's new to VC++ 2005 due to the runtime checks of iterators). I have found 3 ways to solve it but none is what I would like to use. 1. removing the _DEBUG from the preprocessor definitions. 2. undef the _SECURE_SCL before every include to stl. 3. define _imp___CrtDbgReportW as our own function. here is an ...Show All
