How to create a dialog box under Win32 program?

部落小草

I need to add a dialog box under the Win32 program.
I first created a dialog resource and then generated a class using ClassWizard. However, there is always a problem that "stdafx.h" does not exist when compiling! !! !! !! !! !! !! !!
I would like to ask everyone, how to add a dialog box in Win32 program?

Create a WIN32 program, complete
After clicking about, there will be a dialog box

1 Add dialog resources
2 Call the DialogBox function in the WinMain function
3 Define the message processing function of the dialog box, the format refers to MSDN
4 Message mapping

<< Windows Core Programming >> has specific examples in the book

INT_PTR CALLBACK MyDlgProc (HWND hwndDlg,
    UINT uMsg,
    WPARAM wParam,
    LPARAM lParam
); // Window function prototype declaration

BOOL Dlg_OnInitDialog (HWND hwnd, HWND hwndFocus, LPARAM lParam) // Message processing (required)
{

}

VOID Dlg_OnCommand (HWND hwnd, int id, HWND hwndCtl, UINT codeNotify) // Command message processing
{

}

INT_PTR CALLBACK MyDlgProc (HWND hwndDlg,
    UINT uMsg,
    WPARAM wParam,
    LPARAM lParam
)
{
switch (uMsg)
{
case WM_INITDIALOG:
return SetDlgMsgResult (hwndDlg, uMsg, HANDLE_WM_INITDIALOG ((hwndDlg), (wParam), (lParam), (Dlg_OnInitDialog)));
break; //// Message map
case WM_COMMAND:
return SetDlgMsgResult (hwndDlg, uMsg, HANDLE_WM_COMMAND ((hwndDlg), (wParam), (lParam), (Dlg_OnCommand)));
break;

}
return FALSE;
}


int WINAPI WinMain (HINSTANCE hInstance,
    HINSTANCE hPrevInstance,
    LPSTR lpCmdLine,
    int nCmdShow
)
{
DialogBox (hInstance, MAKEINTRESOURCE (IDD_DLG), NULL, MyDlgProc);
}

I know the above method is possible
Is there a method that does not use my own message loop, that is, a method that can display a simple dialog box such as Dlg.Modal

You can encapsulate a dialog call yourself!

hehehehe

Can't use classwizard under win32 program?
Need to use a set of win32 to do. After adding the dialog resource, call
:: DialogBox (...)

Look for a book about WIN32 programming, it will talk about it.

Use pre-compiled, and then run it down.

//First declare the dialog box callback function
LRESULT CALLBACK YourDialog(HWND,UINT,WPARAM,LPARAM);//Callback function of game menu dialog
//Implementation part
LRESULT CALLBACK YourDialog(HWND hDlg,UINT message,WPARAM wParam,LPARAM lParam)
{
    HDC hdc = (HDC)wParam;
switch (message)
{
case WM_INITDIALOG:
return TRUE;

case WM_COMMAND:
if (LOWORD(wParam) == IDOK)
{
EndDialog(hDlg, LOWORD(wParam));
return TRUE;
}
To
break;
                 case XXXXXX:
                      Here you can add other news
                     break;
}
    return FALSE;
}

//Then you need to call the dialog box, such as when you click the left button
DialogBox(hInst, (LPCTSTR)IDD_MENU, hWnd, (DLGPROC)YourDialog)
You can also deal with the return value judgment
switch(DialogBox(hInst, (LPCTSTR)IDD_MENU, hWnd, (DLGPROC)GameMenu))
{
   case OK:
case XXX
At this time the dialog box comes out
