Question
WHY MY WINDOW DOESNT SHOW ?
I've made an C API application that shows a dialog with a textfield and 2 buttons.I use the code below but it doesnt work...it just compile correctly.
#include <windows.h>
#include "resource.h"
#define BUFFER_SIZE 256
BOOL CALLBACK EditDlgProc(HWND hwnd, UINT Message, WPARAM wParam, LPARAM lParam)
{
char szText[BUFFER_SIZE];
switch(Message)
{
case WM_INITDIALOG:
SendDlgItemMessage(hwnd, IDC_EDITDLG_TEXT, EM_SETLIMITTEXT, (WPARAM)BUFFER_SIZE - 1, (LPARAM)0);
return TRUE;
case WM_COMMAND:
switch(LOWORD(wParam))
{
case IDC_EDITDLG_SETTEXT:
GetDlgItemText(hwnd, IDC_EDITDLG_TEXT, szText, BUFFER_SIZE);
SetWindowText(hwnd, szText);
return TRUE;
case IDCANCEL:
EndDialog(hwnd, IDCANCEL);
return TRUE;
}
break;
}
return FALSE;
}
int WINAPI WinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance,
LPSTR lpCmdLine, int nCmdShow)
{
int ret;
ret = DialogBox(hInstance, "EDITDLG", NULL, EditDlgProc);
}
I used the resource editor in VC++ 6 for building the dialog. I forgot to mention that i dont want a "main window" using WNDCLASSEX or stuff like that...Just the dialog.
Anybody knows what happens ?

I'm glad it worked out. I am wishing however to post soon a question about that macro, as I am a bit puzzled about its role. Actually, it converts the ID of the resource to a LPSTR or LPTSTR string, doing some funny conversions there.
#define MAKEINTRESOURCEA(i) (LPSTR) ((DWORD) ((WORD) (i)))
or Unicode:
#define MAKEINTRESOURCEW(i) (LPWSTR) ((DWORD) ((WORD) (i)))
And since the function documentation says there that it should get the template __name__, I wonder what is that template name afterall...
You might want to follow that thread...

Try instead of putting there the string "EDITDLG", using the macro MAKEINTERESOURCE(EDITDLG),
It should work.
MAKEINTRESOURCE takes into account the Unicode representation of the resource name and using the macro is always a good practice. In general,this macro should be used any time a resource is accessed in the program (for bitmaps, icons, menus etc).
