Hello everyone,

 I have a window project in C# VS2005 and using P/Invoke to import a dll file from the API c/c++ and have this error message: "Runtime Error R6034, An application has made an attempt to load the C runtime lib incorrectly.  Please contact the application's support team for more information"  So I'm wondering does anyone knows this problem is and how do you solve it?  Thanks

That error is documented here: http://msdn2.microsoft.com/en-us/library/ms235560.aspx

Without knowing more about the DLL and entry point it is hard to give more assistance, other than the general: this could be a conflict between the C runtime loaded by .NET and that loaded by your target DLL.

Thanks rjcox for replying,

 At first, I thought this could be the manifest problem, So I asked the person to re-modified the program and re-built it with the manifest dll, but still I couldn't import or load the dll into my c# project and call one of the function in the dll. I tested the program itself and it works fine but when I want imported it into my c# project and it failed because of Runtime Error R6034, An application has made an attempt to load the C runtime lib incorrectly
