    Image opening with Visual C++

    Hi everyone,

    I am able to create GUI applications, and can create a window, but I don't know how to work with images. What commands can I use to display a picture in a window? Do you have any examples?

    Thanks.

    Thanks. This is the content of my .rc file:

    Code:
    #include "resource.h"
    #include "windows.h"       
    
    IDB_BITMAP1                BITMAP  DISCARDABLE     "Image.bmp"
    ...However, I get the following compilation error:

    Code:
    fatal error RC1004: unexpected end of file found

    What compiler are you using? In VC++ you should write
    Code:
    #include <windows.h>
    You should include stdafx.h only if you are using precompiled headers and it include file is stdafx.h.

    Please post another code and header file of your program if possible.

    This is related to the source and not to precompiled headers or stdafx.h.
    So, posting your resource.h and the resource file might not be a bad idea.

    Outside of your DOS world, your header file is meaningless.

    Thanks,

    I started with an empty project in the 'General' tab in VC++ 2008 Express. Here is the code:

    Source:

    Code:
    #include <windows.h>
    #include <stdafx.h>
    #include "Resource.h"
    
    HINSTANCE hInst;
    LRESULT CALLBACK WindProcedure(HWND hWnd, UINT Msg, WPARAM wParam, LPARAM lParam);
    
    INT WINAPI WinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance,
                       LPSTR lpCmdLine, int nCmdShow)
    {
        WNDCLASSEX  WndCls;
        static char szAppName[] = "BitmapIntro";
        MSG         Msg;
    
    	hInst       = hInstance;
        WndCls.cbSize        = sizeof(WndCls);
        WndCls.style         = CS_OWNDC | CS_VREDRAW | CS_HREDRAW;
        WndCls.lpfnWndProc   = WindProcedure;
        WndCls.cbClsExtra    = 0;
        WndCls.cbWndExtra    = 0;
        WndCls.hInstance     = hInst;
        WndCls.hIcon         = LoadIcon(NULL, IDI_APPLICATION);
        WndCls.hCursor       = LoadCursor(NULL, IDC_ARROW);
        WndCls.hbrBackground = (HBRUSH)GetStockObject(WHITE_BRUSH);
        WndCls.lpszMenuName  = NULL;
        WndCls.lpszClassName = szAppName;
        WndCls.hIconSm       = LoadIcon(hInstance, IDI_APPLICATION);
        RegisterClassEx(&WndCls);
    
        CreateWindowEx(WS_EX_OVERLAPPEDWINDOW,
                              szAppName,
                              "Bitmap",
                              WS_OVERLAPPEDWINDOW | WS_VISIBLE,
                              CW_USEDEFAULT,
                              CW_USEDEFAULT,
                              CW_USEDEFAULT,
                              CW_USEDEFAULT,
                              NULL,
                              NULL,
                              hInstance,
                              NULL);
    
        while( GetMessage(&Msg, NULL, 0, 0) )
        {
            TranslateMessage(&Msg);
            DispatchMessage( &Msg);
        }
    
        return static_cast<int>(Msg.wParam);
    }
    
    LRESULT CALLBACK WindProcedure(HWND hWnd, UINT Msg,
    			   WPARAM wParam, LPARAM lParam)
    {
        HDC hDC, MemDCExercising;
        PAINTSTRUCT Ps;
        HBITMAP bmpExercising;
    
        switch(Msg)
        {
    	case WM_DESTROY:
    	    PostQuitMessage(WM_QUIT);
    	    break;
    	case WM_PAINT:
    	    hDC = BeginPaint(hWnd, &Ps);
    
    	    bmpExercising = LoadBitmap(hInst, MAKEINTRESOURCE(IDB_BITMAP1));
    	    MemDCExercising = CreateCompatibleDC(hDC);
                 SelectObject(MemDCExercising, bmpExercising);
    
    	    BitBlt(hDC, 10, 10, 450, 400, MemDCExercising, 0, 0, SRCCOPY);
    
    	    DeleteDC(MemDCExercising);
    	    DeleteObject(bmpExercising);
    	    EndPaint(hWnd, &Ps);
    	    break;
    	default:
    	    return DefWindowProc(hWnd, Msg, wParam, lParam);
        }
        return 0;
    }
    Resource (I have no idea how to write a Bitmap resource):
    Code:
    #include "resource.h"
    #include "windows.h"       
    
    IDB_BITMAP1     BITMAP  DISCARDABLE     "C:\Documents and Settings\XP\My Documents\My 
    
    Pictures\Image.bmp"
    Header:

    Code:
    #include "windows.h"
    
    #define IDB_BITMAP1               1000
    Thanks.

    I've managed it another way - I think it may have been my resource editor program that wasn't set up properly, as I re-made my .rc file, and it gave me this:

    Code:
    #include <windows.h>
    #include <commctrl.h>
    #include <richedit.h>
    #include "resource.h"
    
    
    LANGUAGE LANG_NEUTRAL, SUBLANG_NEUTRAL
    IDB_BITMAP1        BITMAP         "bitmap1.bmp"

    I don't know how to do that - how do I embed images on this forum? Here is another hyperlink:

    Link

    The next thing I am interested in doing is downloading an image from the net and displaying it in that frame. For example, if I want to download this image every time the program starts:

    http://sohowww.nascom.nasa.gov/data/...024/latest.jpg

    Is this hard t do?

    Thanks.

    So you can't load images yet and you already want to do another task related to images? Google is your friend. Do a little research and come back with a specific directed question about the problems you are having and we can offer more assistance.
