Problem mit Manifest

[christiankl1]

Hallo zusammen,

ich bin recht neu in der WINAPI Programmierung und stehe vor folgenden Problem.
Ich programmiere mit Code::Blocks 10.5 und sobald ich in meiner Windows GUI Anwendung das Windows Look'n'Feel hinzufüge wird eine Manifestdatei angelegt die für den visuelle Style sorgt. Alles schön und gut soweit, unter Vista und Windows 7 funktioniert das Programm auch einwandfrei nur unter Windows XP gibt es Probleme.

main.cpp

#include <windows.h>
#include "resource.h"

/*  Declare Windows procedure  */
LRESULT CALLBACK WindowProcedure (HWND, UINT, WPARAM, LPARAM);

/*  Make the class name into a global variable  */
char szClassName[ ] = "AppName";

int WINAPI WinMain (HINSTANCE hThisInstance,
                     HINSTANCE hPrevInstance,
                     LPSTR lpszArgument,
                     int nCmdShow)
{
    HWND hwnd;               /* This is the handle for our window */
    MSG messages;            /* Here messages to the application are saved */
    WNDCLASSEX wincl;        /* Data structure for the windowclass */

    /* The Window structure */
    wincl.hInstance = hThisInstance;
    wincl.lpszClassName = szClassName;
    wincl.lpfnWndProc = WindowProcedure;      /* This function is called by windows */
    wincl.style = CS_DBLCLKS;                 /* Catch double-clicks */
    wincl.cbSize = sizeof (WNDCLASSEX);

    /* Use default icon and mouse-pointer */
    wincl.hIcon = LoadIcon (hThisInstance, MAKEINTRESOURCE(ID_ICON));
    wincl.hIconSm = LoadIcon (hThisInstance, MAKEINTRESOURCE(ID_ICON));
    wincl.hCursor = LoadCursor (NULL, IDC_ARROW);
    wincl.lpszMenuName = NULL;                 /* No menu */
    wincl.cbClsExtra = 0;                      /* No extra bytes after the window class */
    wincl.cbWndExtra = 0;                      /* structure or the window instance */
    /* Use Windows's default colour as the background of the window */
    wincl.hbrBackground = (HBRUSH) (COLOR_WINDOW+1);

    /* Register the window class, and if it fails quit the program */
    if (!RegisterClassEx (&wincl))
        return 0;

    /* The class is registered, let's create the program*/
    hwnd = CreateWindowEx (
           0,                   /* Extended possibilites for variation */
           szClassName,         /* Classname */
           "AppName",           /* Title Text */
           WS_OVERLAPPEDWINDOW, /* default window */
           CW_USEDEFAULT,       /* Windows decides the position */
           CW_USEDEFAULT,       /* where the window ends up on the screen */
           544,                 /* The programs width */
           575,                 /* and height in pixels */
           HWND_DESKTOP,        /* The window is a child-window to desktop */
           NULL,                /* No menu */
           hThisInstance,       /* Program Instance handler */
           NULL                 /* No Window Creation data */
           );

    // Hauptfenster auf Bildschirm zentrieren
    RECT rect;
    GetWindowRect(hwnd, &rect);

    int width = rect.right - rect.left;
    int height = rect.bottom - rect.top;

    int left = GetSystemMetrics(SM_CXSCREEN) / 2 - width / 2;
    int top = GetSystemMetrics(SM_CYSCREEN) / 2 - height / 2;

    SetWindowPos(hwnd, NULL, left, top, 0, 0, SWP_NOSIZE);

    /* Make the window visible on the screen */
    ShowWindow (hwnd, nCmdShow);

    /* Run the message loop. It will run until GetMessage() returns 0 */
    while (GetMessage (&messages, NULL, 0, 0))
    {
        /* Translate virtual-key messages into character messages */
        TranslateMessage(&messages);
        /* Send message to WindowProcedure */
        DispatchMessage(&messages);
    }

    /* The program return-value is 0 - The value that PostQuitMessage() gave */
    return messages.wParam;
}

/*  This function is called by the Windows function DispatchMessage()  */

LRESULT CALLBACK WindowProcedure (HWND hwnd, UINT message, WPARAM wParam, LPARAM lParam)
{
    switch (message)                  /* handle the messages */
    {
        case WM_CREATE:
        MessageBox(hwnd, "Test", "Haha", MB_YESNO);
        break;
        case WM_DESTROY:
            PostQuitMessage (0);       /* send a WM_QUIT to the message queue */
            break;
        default:                      /* for messages that we don't deal with */
            return DefWindowProc (hwnd, message, wParam, lParam);
    }

    return 0;
}

resource.h

#include <windows.h>

#define ID_ICON 1

resource.rc

#include "resource.h"

ID_ICON              ICON        "Icon.ico"

appName.exe.Manifest

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<assembly
  xmlns="urn:schemas-microsoft-com:asm.v1"
  manifestVersion="1.0">

    type="win32"/>

        <assemblyIdentity
            type="win32"

            language="*"
        />
    </dependentAssembly>
</dependency>
</assembly>

In Windows XP wird die MessageBox nicht zu Beginn angezeigt, erst wenn ich die Manifestdatei lösche. Ich frage mich wieso.

Danke für eure Hilfe

Mt freundlichen Grüßen

Vor Deinem Aufruf von CreateWindowEx fehlt noch der Aufruf von InitCommonControls oder InitCommonControlsEx.
