I have to build a project. For that I am using an
OWNER Drwan Menu. Now i want the small part of the
remaining space to have an image. i.e a small logo
in the top right corner of the application on the
menu bar unused space. Now to dry that I just typed
a code to display an image somewahere in the main
window. But the output is not showing the Bitmap.
Why is that.
What is the probelm with the below code
#include <windows.h>
#include"resource.h"
#define ID_FILE_EXIT 9001
#define ID_STUFF_GO 9002
const char g_szClassName[] = "myWindowClass";
HINSTANCE hInstance;
LRESULT CALLBACK WndProc(HWND hwnd, UINT Message,
WPARAM wParam, LPARAM lParam)
{
HDC hDC, MemDCExercising;
PAINTSTRUCT Ps;
HBITMAP bmpExercising;
switch(Message)
{
case WM_CREATE:
{
HMENU hMenu, hSubMenu;
hMenu = CreateMenu();
hSubMenu =
CreatePopupMenu();
AppendMenu(hSubMenu,
MF_STRING, ID_FILE_EXIT, "E&xit");
AppendMenu(hMenu, MF_STRING
| MF_POPUP, (UINT)hSubMenu, "&File");
hSubMenu =
CreatePopupMenu();
AppendMenu(hSubMenu,
MF_STRING, ID_STUFF_GO, "&Go");
AppendMenu(hMenu, MF_STRING
| MF_POPUP, (UINT)hSubMenu, "&Stuff");
SetMenu(hwnd, hMenu);
}
break;
case WM_PAINT:
{
hDC =
BeginPaint(hwnd, &Ps);
// Load the bitmap
from the resource
bmpExercising =
LoadBitmap(hInstance,
MAKEINTRESOURCE(IDB_EXERCISING));
// Create a memory
device compatible with the above DC variable
MemDCExercising =
CreateCompatibleDC(hDC);
// Select
the new bitmap
SelectObject(MemDCExercising, bmpExercising);
// Copy the bits
from the memory DC into the current dc
BitBlt(hDC, 200,
200, 200, 200, MemDCExercising, 0, 0, SRCCOPY);
// Restore the old
bitmap
DeleteDC(MemDCExercising);
DeleteObject(bmpExercising);
EndPaint(hwnd,
&Ps);
}
break;
case WM_COMMAND:
switch(LOWORD(wParam))
{
case ID_FILE_EXIT:
PostMessage(hwnd, WM_CLOSE, 0, 0);
break;
case ID_STUFF_GO:
break;
}
break;
case WM_CLOSE:
DestroyWindow(hwnd);
break;
case WM_DESTROY:
PostQuitMessage(0);
break;
default:
return DefWindowProc(hwnd,
Message, wParam, lParam);
}
return 0;
