Hey, I''m using this block of code from a game programing book as an example in Visuall C++ 6.0. everytime I try to compile it it says " Cannot execute program " What am I missing here? ( Note, I took out the <> so you could see the code, so besides those) // PROG3_2.CPP - A simple message box #define WIN32_LEAN_AND_MEAN #include windows.h #include windowsx.h // main entry point for all windows programs int WINAPI WinMain(HINSTANCE hinstance, HINSTANCE hprevinstance, LPSTR lpcmdline, int ncmdshow) { // call message box api MessageBox(NULL, "What''s up world!", "My First Windows Program",MB_OK); // exit program return(0); } // end WinMain

Its not ncmdshow, it is int nShowCmd

lol. Good luck.

what project settings did you use ??

it looks like your visual C++ settings cannot find your exe file.

btw, nCmdShow does mean anything if you dont make a window or show it.


check your project settings. Try to double click the exe and see what happens.



{ Stating the obvious never helped any situation !! }

Is that all it said was "Cannot execute program"? If so, then yeah, give us your project settings.

If you want to use < and > in your post, just type &lt; and &gt;.

The compiler could care less, just so long as it is of type int.

Thanx, actually, it was my project settings. It wasn''t set up right, I got it working now, but I''ve hit another spot.

In creating the classes for Windows, where dose this part go in the program:

typedef struct _WNDCLASS
{

UINT style;
WNDPROC lpfnWndProc;
int cbClsExtra;
int cbWndExtra;
HANDLE hInstance;
HICON hIcon;
HCURSOR hCursor;
HBRUSH hbrBackground;
LPCTSTR lpszMenuName;
LPCTSTR lpszClassName;

} WNDCLASS;

WNDCLASS wndclass;



and where dose all of this information about the things in the structure go? :


wndclass.style = CS_DBLCKS | CD_OWNDC |
CS_HREDRAW | CS_VREDRAW;

wndclass.lpfnWndProc = WindowProc;


wndclass.cbClsExtra = 0;
wndclass.cbWndExtra = 0;

wndclass.hInstance = hinstance;

wndclass.hIcon =LoadIcon(NULL, IDI_APPLICATION);

wndclass.hCursor = LoadCursor =(NULL, IDC_ARROW);

wndclass.hbrBackground= (HBRUSH)GetStockObject(BLACK_BRUSH);

wndclass.lpszMenuName= NULL;

wndclass.lpszClassName = "WINCLASS1";



thanx again.

You dont have to actually declare the wndclass struct because its already defined. You fill out the wndclass struct pretty much right after WinMain():

int WINAPI WinMain(HINSTANCE hinstance,                   HINSTANCE hprevinstance,                   LPSTR lpcmdline,                   int ncmdshow){    MSG msg;    WNDCLASSEX wcex;    wcex.cbSize = sizeof(WNDCLASSEX);     wcex.style			= CS_HREDRAW | CS_VREDRAW;    wcex.lpfnWndProc	= (WNDPROC)WndProc;    wcex.cbClsExtra		= 0;    wcex.cbWndExtra		= 0;    wcex.hInstance		= hInstance;    wcex.hIcon			= LoadIcon(hInstance,                                           (LPCTSTR)IDI_MY2);    wcex.hCursor		= LoadCursor(NULL, IDC_ARROW);    wcex.hbrBackground	= (HBRUSH)(COLOR_WINDOW+1);    wcex.lpszMenuName	= (LPCSTR)IDC_MY2;    wcex.lpszClassName	= szWindowClass;    wcex.hIconSm		= LoadIcon(wcex.hInstance,                                           (LPCTSTR)IDI_SMALL);    RegisterClassEx(&wcex);//Create window//update window//show window//Main message loop  

Of course it doesnt have to go right here it just has to go before you create the window etc.

Hope this helps
