error C2664: 'DialogBoxParamA' : cannot convert parameter 4 from 'int (void *,unsigned int,unsigned int,long)' to 'int (__stdcall *)(void)'
[\source]
I am assuming that the file name endings tell the compiler to compile in c or c++. And am wondering why my dialog box code wont compile under C++. Oh yeah I am using MS VC++ 5.0...
here is my code:
[source]
BOOL CALLBACK AboutDlgProc(HWND, UINT, WPARAM, LPARAM);
//window procedure
BOOL CALLBACK AboutDlgProc(HWND hWndDlg, UINT Message, WPARAM wParam, LPARAM lParam)
{
switch(Message)
{
case WM_INITDIALOG:
return TRUE;
case WM_COMMAND:
switch(LOWORD(wParam))
{
case IDOK:
EndDialog(hWndDlg, 0);
return TRUE;
case IDC_LINKBUTTON:
ShellExecute(NULL, "open", "http://www.keanecircuits.com", NULL, NULL, SW_SHOWDEFAULT);
break;
}
break;
}
return FALSE;
}
//how I create the dialog box(line where error occurs)
DialogBox(hInstance, "ABOUTDLG", hWndMain, AboutDlgProc);
[\source]
Has anybody experienced a problem like this before, or can help me out???

I am having problems setting up a dialog box. When I try to compile my code when it is named mycode.c, it compiles perfectly, but when try to compile when it is names mycode.cpp, I get this error:
add this line before including any headers:
#define STRICT
should help.

Does you prototype and definition of AboutDlgProc look like this?
BOOL CALLBACK AboutDlgProc(HWND,UINT ,WPARAM , LPARAM );
BOOL CALLBACK AboutDlgProc(HWND hAbout,UINT msg,WPARAM wParam,
LPARAM lParam)
{
whatever !
}
maybe !!!
BOOL CALLBACK AboutDlgProc(HWND,UINT ,WPARAM , LPARAM );
BOOL CALLBACK AboutDlgProc(HWND hAbout,UINT msg,WPARAM wParam,
LPARAM lParam)
{
whatever !
}
maybe !!!
Try this:
////////
DialogBox(hInstance, "ABOUTDLG", hWndMain, (DLGPROC) AboutDlgProc);
////////
////////
DialogBox(hInstance, "ABOUTDLG", hWndMain, (DLGPROC) AboutDlgProc);
////////
quote:Original post by doctorsixstring
DialogBox(hInstance, "ABOUTDLG", hWndMain, (DLGPROC) AboutDlgProc);
it''s better to use STRICT, you get type safety => catch more errors at compile-time rather than at run-time.
