Intellisense says: 2 IntelliSense: cannot open source file "c:/users/####/documents/visual studio 2010/Projects/modlauch/modlauch/Debug/dwmapi.tlh": Bad file descriptor c:\users\####\documents\visual studio 2010\projects\modlauch\modlauch\modlauchdlg.cpp 7 1 modlauch Does anyone know how to solve it? I'm sure that my 'dwmapi' library is fine and there is nothing wrong with it. I'm using MFC with VS2010 , but I don't think that is related to the http://stackoverflow.com/questions/2276481/error-loading-type-library-dll problem. (Platform - Win32) If I get rid of "#import" then I get "unresolved external symbol _imp_DwmExtendFrameIntoClientArea@8" error. c++ mfc visual-studio-2010 winapi share|improve this question edited Feb 18 '10 at 8:03 Yacoby 37.6k889110 asked Feb 16 '10 at 21:27 Kristina Brooks 5,9831471146 add a comment| 3 Answers 3 active oldest votes up vote 5 down vote accepted dwmapi .lib is a type library?

The DLL is written in Visual Studio C++ 2008 SP1 and I am using MATLAB R2009b (64bit). I have also installed Microsoft SDK Developer Tools. The DllTest.cpp file is: #include "DllTest.h" #include #ifdef __cplusplus extern error loading use "C" { #endif __declspec(dllexport) double Add(double a) { return(a); } #ifdef __cplusplus } #endif And DllTest.h is: #ifndef _DLL_TEST_H_ #define _DLL_TEST_H_ #include #ifdef __cplusplus extern "C" { #endif __declspec(dllexport) double Add( double a); #ifdef __cplusplus } #endif #endif Visual studio successfully builds the DLL. But, when I want to import the DLL, following error is generated: >> loadlibrary('DllTest.dll', 'DllTest.h'); ??? Error using ==> loadlibrary at 474 There was an error loading the library "C:\Users\Admin\Desktop\DllTest.dll" C:\Users\Admin\Desktop\DllTest.dll is not a valid Win32 application. Caused by: Error using ==> loaddefinedlibrary C:\Users\Admin\Desktop\DllTest.dll is not a valid Win32 application. I cannot understand what I am missing. Please help me fix the problem.
