Allright, thanks a lot!

Hello, I've created a .htm help file and i'd like to open with IE it from within my program. Such thing does not seem as easy as I thought. If anyone could help me out it will be greatly appreciated. best regards, Jan Timmerman.

Hello, Is it possible to throw the entire content of the Class View to the printer to create a listing of all classes and classmembers? best regards, Jan Timmerman

Great, it works! i've modified the function call to extern "C" void __cdecl extiteratie( [arguments] ) (from the error messages I noticed the compiler ignores the "__declspec(dllimport)" part when including __cdecl) Also I added an underscore to the function export in the Fortran code which was needed by __cdecl. An alternative is (most likely but not tested) to use __stdcall in the export. I do not think it makes much difference whether I use __stdcall or __cdecl? Thanks a lot! Jan Timmerman

Thanks for your reply: Well that was about where I was aiming at. I never heard of the "#import" directive before so I will have to look into that. I have not too much experience with Visual studio. Perhaps I should explain a little more about the situation. Currently I have a ".lib" and a ".dll" generated by Compaq Visual Fortran. I've declared the function called from the .dll as follows: extern "C" void __declspec(dllimport) extiteratie( [arguments] ) First I get the warning: TFortranInterface.cpp(27) : warning C4272: 'extiteratie' : is marked __declspec(dllimport); must specify native calling convention when importing a function. after that an error error LNK2031: unable to generate p/invoke for "extern "C" void __clrcall extiteratie( float*, float*, (...) float* )" (?extiteratie@@$$J0YMXPAM000000000000000PAH110@Z); calling convention missing in metadata (After this an unresolved token error which is most likely caused by the previous error.) I am currently using a native class as interface because I need to pass the function in the .dll a set of pointers which will be filled with results. The questions: 1. With /clr:pure I cannot use that native class? 2. Any idea what the error could mean (and/or perhaps an alternate declaration for the function in the .dll?) (3. what does #import do?) best regards, Jan Timmerman

Hello, Is it possible to include a .dll in a /clr:pure project? I am currently using unmanaged code for this. I was wondering if it is also possible with a /clr:pure project which does not allow native C++? Including a .dll can be done with C#. (Full setting is "Pure MSIL Common Language Runtime Support (/clr:pure)" in the project properties -> General) best regards, Jan Timmerman

Perhaps that might work. This does not explain though why it is allowed to say int test; in stdafx.h (which is included also in a lot of places) Also I thought int test; is a declaration here. It would be illegal to write int test=3;. I will give your suggestions a closer look, thanks for your quick replies! -- modified at 7:47 Monday 6th March, 2006 Well, it works, thanks a lot!

Hello, I was experiencing a strange error that I tracked down to be a declaration in Form1.h I attemped to reproduce the problem in a brand new project and to my surprise: the error appeared again. In the new "windows forms" project test1.cpp: #include "stdafx.h" #include "form1.h" Added to form1.h int test; error: test.obj : error LNK2005: "int test" (?test@@$$Q3HA) already defined in IncludeTest.obj D:\VC\IncludeTest\Debug\IncludeTest.exe : fatal error LNK1169: one or more multiply defined symbols found. I have tried int test in stdafx.h. This does compile though stdafx.h is also included in both the main and test.cpp. Project available here (44k, created with VC++ 2005) I thought this was according to c++ language rules, but apparently I am doing something wrong? Best regards, Jan Timmerman

Ok, it builds. Only thing that remains is the warning. Thanks for the help!

Hello, I am new to Visual C++ (not to C++ though) and I am trying to draw a curve with GDI+. Since I kept getting the same linker errors, I made a new project in which I only included <windows.h> and <gdiplus.h>. The result: first this warning: (all linker errors) warning LNK4248: unresolved typeref token (0100001A)for 'Gdiplus.GpCachedBitmap'; image may not run And then several errors of this type error LNK2028: unresolved token (0A000049) "extern "C" enum Gdiplus::Status __stdcall GdipCloneImage(class Gdiplus::GpImage *,class Gdiplus::GpImage * *)" (??1PrivateFontCollection@Gdiplus@@$$FUAM@XZ) I have installed Visual C++ 2005 Express and the Windows Server 2003 SDK and added the path to the VC++ Directories. Running on XP with SP2 Thanks in advance. Best regards, Jan Timmerman -- modified at 3:09 Thursday 9th February, 2006
