'chaining' a splash screen and the main window

[bonobo]

Hello,

I have an application that launches a dialog box on start (that's what I call splash screen)
and when it closes, the application crashes before calling winMain.

(DialogBoxParam returns to some place in user32)

Code Select Expand


.586
.model flat,stdcall
option casemap:none

.CODE

start:
invoke GetModuleHandle, NULL
mov hInstance,eax
invoke GetCommandLine
mov CommandLine,eax

;******splash screen******
INVOKE DialogBoxParam,hInstance,IDD_SPLASH,NULL,ADDR SplashProc,NULL

;******WinMain******
invoke WinMain,hInstance,NULL,CommandLine, SW_SHOWDEFAULT
invoke ExitProcess, eax

SplashProc proc uses esi edi ebx hWnd:DWORD,uMsg:DWORD,wParam:DWORD,lParam:DWORD
.IF uMsg == WM_COMMAND
    mov eax,wParam
    mov edx,eax
    shr edx,16
    and eax,0FFFFh
    .if edx==BN_CLICKED
        .if eax==SPLASH_CLOSE
            invoke EndDialog,hWnd,NULL
            push 0
            call ExitProcess
        .elseif eax==SPLASH_CONTINUE
            invoke EndDialog,hWnd,NULL
        .endif
    .endif
.ELSEIF uMsg == WM_CLOSE
    invoke SendMessage,hWnd,WM_COMMAND,SPLASH_CLOSE,0
.ENDIF
    mov eax, FALSE
ret ;here returns to user32
SplashProc endp

WndProc proc uses esi edi ebx hWnd:HWND, uMsg:UINT, wParam:WPARAM, lParam:LPARAM
WndProc endp

WinMain proc hInst:HINSTANCE,hPrevInst:HINSTANCE,CmdLine:LPSTR,CmdShow:DWORD
WinMain endp

end start


The message handling works fine (clicks on buttons are triggered) and the WinMain works fine when the splash screen is not there.

thanks for any help

I can't test this, but I suspect the problem is the call to ExitProcess in SplashProc.

I can't test this, but I suspect the problem is the call to ExitProcess in SplashProc.

I can't see why it would be a problem?
The exit button works fine. It's on ly when I press continue that it crashes.
The program exits the .IF/.ENDIF and when it reaches the last RET, it crashes.
