Images and dialog boxes

[george7378]

Hi everyone,

I have the following code which displays an image in a picture frame on a dialog box:

#include "windows.h"
#include <cstdio>
#include "resource.h" 
#include <tchar.h>
#include <urlmon.h>
#include <iostream>
#include "stdlib.h"

#pragma comment(lib, "urlmon.lib")

BOOL CALLBACK ToolDlgProc(HWND hwnd, UINT Message, WPARAM wParam, LPARAM lParam)
{
	switch(Message)
	{
		case WM_COMMAND:
			switch(LOWORD(wParam))
			{
				case IDC_SUN:
					DialogBox(GetModuleHandle(NULL), MAKEINTRESOURCE(IDD_SUNPAGE), hwnd, ToolDlgProc);
				break;
							
				case IDC_CLOSEASTRO:
					EndDialog(hwnd, 0);
				break;
				
				case IDC_MOON:
					break;

				case IDC_ABOUT:
                    DialogBox(GetModuleHandle(NULL), MAKEINTRESOURCE(IDD_ABOUT), hwnd, ToolDlgProc);
			    break;

				case IDC_ABOUTOK:
					EndDialog(hwnd, 0);
				break;

				case IDC_STARTLOAD:
					EndDialog(hwnd, 0);
					DialogBox(GetModuleHandle(NULL), MAKEINTRESOURCE(IDD_MAIN), hwnd, ToolDlgProc);
				break;

			}
		break;

		case WM_CLOSE:
			EndDialog(hwnd, 0);
		    break;

		default:
			return FALSE;
	}
	return TRUE;
}

int WINAPI WinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance,
	LPSTR lpCmdLine, int nCmdShow)
{
	return DialogBox(hInstance, MAKEINTRESOURCE(IDD_MAIN), NULL, ToolDlgProc);
}

Here is the resource file:

LANGUAGE LANG_NEUTRAL, SUBLANG_NEUTRAL
IDB_SUNPIC        BITMAP DISCARDABLE         "C:\\Documents and Settings\\XP\\My Documents\\latest.bmp"

IDD_SUNPAGE DIALOG 0, 0, 490, 352
STYLE DS_3DLOOK | DS_CENTER | DS_MODALFRAME | DS_FIXEDSYS | WS_VISIBLE | WS_BORDER | WS_CAPTION | WS_DLGFRAME | WS_POPUP | WS_SYSMENU
CAPTION "Latest Sun"
FONT 8, "Ms Shell Dlg 2"
{
    CONTROL         IDB_SUNPIC, IDC_SUNFRAME, WC_STATIC, SS_BITMAP, 30, 12, 341, 236
}

I have created the bitmap and picture frame resources in the RC file, and assigned the bitmap to the frame in the above line. When I run the program, the image displays, but if I change the image and restart the program, it stays the same when the program displays it. How do I make it refresh the image?

Thanks.
