    Having some trouble setting up Dev-c++ for DX

    Ok heres my trouble. i am using a tutorial i got. its very comprehensive and full of great setup information... if i was using MSVC++.
    I am using Dev c++ for my Compiler, and i have been trying to set it up for DX.
    i've told it where the DX include folder is,
    added a call for -fvtable-thunks when it compiles. and nothing more so far. with the suplied code it get the following errors
    c:\documents and settings\stephen\my documents\c++\direct x 8\test.cpp:146: ANSI C++ forbids implicit conversion from `void *' in argument passing

    c:\documents and settings\stephen\my documents\c++\direct x 8\test.cpp:161: ANSI C++ forbids implicit conversion from `void *' in argument passing

    I see this as it saying i can't pass a void dereferencer to the function,. if this a problem with the code <direct copy/paste> or have i not finished setting up Dev-C++. I've look on board threw the seach and on google, most tutorials and help i found was for MSVC++ and not dev-c++
    I'm suplying the code in case theres a problem with it or something to that effect.
    Thanks a lot for nay help.

    Please copy and paste the exact compiler log. DevC++ unfortunatly cuts off the end of the compilers errormessages in the "compiler" tab. They are intact in the "compile log" tab.

    The highlighted lines do not contain any mistakes.

    here you go. thanks for your time. <i tohugh the code looked fine..>
    in the first on it doesn't like the last null
    and in second one, it doesn't like the second parameter wc.Hintance


    c:\documents and settings\stephen\my documents\c++\direct x 8\test.cpp: In function `int WinMain(HINSTANCE__ *, HINSTANCE__ *, CHAR *, int)':

    AHH the solution was simple
    I'm on XP, and in both calls, wc.hInstance should be set to NULL as irts ignore in NT!
    god bless the msdn
    thanks for help, your saying that code was fine made me think, i think the problem is with final null, but what if its just because when i split it into multiple lines it just reports problem for last paramter of function. i quickly looked over to a normsal windows app i saw i used null there, then reference MSDN to see why

    Uhm... well at a second thought... that can't really be the problem because I use hInstance in my code, too. I think the problem is....

    Code:
        WNDCLASSEX wc = {sizeof(WNDCLASSEX), CS_CLASSDC, WinProc, 0L, 0L,
                         GetModuleHandle(NULL), NULL, NULL, NULL, NULL,
                         "DX Project 1", NULL};
    I think you are not allowed to use function return values in an initializer.
    You "solved" the problem by removing GetModulehandle.

    This code uses hInstance and it runs on WinXP (don't copy it, it's meant to be used by RegisterClass and not RegisterClassEx)

    Code:
    	p->hInstance= GetModuleHandle(NULL);
    
    	wc.style=         CS_HREDRAW | CS_VREDRAW | CS_OWNDC;
    	wc.lpfnWndProc=   WndProc;
    	wc.cbClsExtra=    0;
    	wc.cbWndExtra=    0;
    	wc.hInstance=     p->hInstance;
    	wc.hIcon=         LoadIcon(NULL, IDI_WINLOGO);
    	wc.hCursor=       LoadCursor(NULL, IDC_ARROW);
    	wc.hbrBackground= NULL;
    	wc.lpszMenuName=  NULL;
    	wc.lpszClassName= "BlackMagic";
    
    	if (!RegisterClass(&wc)) {
    		MessageBox(NULL,"Failed To Register The Window Class.","ERROR", MB_OK|MB_ICONEXCLAMATION);
    		return FALSE;
    	}
    which means it's ok to pass an instance, windows XP just ignores it. Try to set hInstance outside of the initializer (set it to NULL in the { } and then add wc.hInstance= GetModuleHandle(NULL);. Otherwise you'll probably get into problems on non-XP Windows'.

    Got it, thansk a lot.
    What i did was i called
    HINSTANCE Ninst = GetModuleHandel(NULL)
    and used that when ever i need in Handel. words like a charm
