Parent not repainting Bitmp after child window closes
Can someone take a look at my code and see if I'm missing something thats causing my parent window not to repaint the bitmap.
Code:
#include <windows.h>
#include <commdlg.h>
#include "resource.h"
#include "Functions.h"
#include "Variables.h"
int WINAPI WinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance,
LPSTR lpCmdLine, int nCmdShow)
{
WNDCLASSEX wc; //Structure and call RegisterClassEX()
HWND MainWindow;
MSG Msg;
wc.cbSize = sizeof(WNDCLASSEX); //Size of the structure
wc.style = CS_HREDRAW |CS_VREDRAW; //Class Styles(cs_*), not be confused withwindow Styles(WS_*)This can usually be set to 0.
wc.lpfnWndProc = WndProc; //Pointer to the window procedure for this window class.
wc.cbClsExtra = 0; //Amount of extra data allocated for this class in memory. Usually 0.
wc.cbWndExtra = 0; //Amount of extra data allocatedin memory per window of this type. Usually 0.
wc.hInstance = hInstance; //Handle to application instance( that I got in the first parameter of WinMain().
wc.hCursor = LoadCursor(NULL, IDC_ARROW); //Cursor that will be displayed over the window.
wc.hbrBackground= (HBRUSH) GetStockObject (WHITE_BRUSH);//Background brush to set the color of the window.
wc.lpszMenuName = NULL; //Name of a menu resource to use for the windows with this class.
wc.lpszClassName= main_window; //Name to identify the class with.
wc.hIcon = LoadIcon(GetModuleHandle(NULL), MAKEINTRESOURCE(IDI_ICON1));
wc.hIconSm = (HICON)LoadImage(GetModuleHandle(NULL), MAKEINTRESOURCE(IDI_ICON1), IMAGE_ICON, 16, 16, 0);
if(!RegisterClassEx(&wc)) // To check for failure
{
MessageBox(NULL, "Window Registration Failed!", "Error!",
MB_ICONEXCLAMATION | MB_OK);
return 0;
}//End of IF
