windows sdk 的问题？
以下程序，在窗口中显示非模式对话框，但却显示不出来，对话框风格已指定了WS_VISIBLE。
请高手指教：
#include <windows.h>
#include "resource.h"
LRESULT CALLBACK WndProc (HWND, UINT, WPARAM, LPARAM) ;
BOOL CALLBACK AboutDlgProc (HWND, UINT, WPARAM, LPARAM) ;
HWND idlg;
int WINAPI WinMain (HINSTANCE hInstance, HINSTANCE hPrevInstance,
PSTR szCmdLine, int iCmdShow)
{
static TCHAR szAppName[] = TEXT ("About3") ;
MSG msg ;
HWND hwnd ;
WNDCLASS wndclass ;
wndclass.style = CS_HREDRAW | CS_VREDRAW ;
wndclass.lpfnWndProc = WndProc ;
wndclass.cbClsExtra = 0 ;
wndclass.cbWndExtra = 0 ;
wndclass.hInstance = hInstance ;
wndclass.hIcon = LoadIcon (hInstance, szAppName) ;
wndclass.hCursor = LoadCursor (NULL, IDC_ARROW) ;
wndclass.hbrBackground = (HBRUSH) GetStockObject (WHITE_BRUSH) ;
wndclass.lpszMenuName = szAppName ;
wndclass.lpszClassName = szAppName ;
if (!RegisterClass (&wndclass))
{
MessageBox (NULL, TEXT ("This program requires Windows NT!"),
szAppName, MB_ICONERROR) ;
return 0 ;
}
hwnd = CreateWindow (szAppName, TEXT ("About Box Demo Program"),
WS_OVERLAPPEDWINDOW,
CW_USEDEFAULT, CW_USEDEFAULT,
CW_USEDEFAULT, CW_USEDEFAULT,
NULL, NULL, hInstance, NULL) ;
idlg=CreateDialog(hInstance,MAKEINTRESOURCE(IDD_DIALOG),GetDesktopWindow() ,(DLGPROC)AboutDlgProc);
ShowWindow (hwnd, iCmdShow) ;
UpdateWindow (hwnd) ;
while (GetMessage (&msg, NULL, 0, 0))
{ if(idlg==0||!IsDialogMessage(idlg,&msg))
TranslateMessage (&msg) ;
DispatchMessage (&msg) ;
}
return msg.wParam ;
}
LRESULT CALLBACK WndProc (HWND hwnd, UINT message, WPARAM wParam, LPARAM lParam)
{
static HINSTANCE hInstance ;
HDC hdc;
switch (message)
{
case WM_CREATE :
hInstance = ((LPCREATESTRUCT) lParam)->hInstance ;
return 0 ;
case WM_COMMAND :
switch (LOWORD (wParam))
{
case IDM_APP_ABOUT :
hdc=GetDC(hwnd);
TextOut(hdc,40,50,TEXT("jdfkdf"),7);ReleaseDC(hwnd,hdc);
return 0 ;
}
break ;
case WM_DESTROY :

return 0 ;
}
return DefWindowProc (hwnd, message, wParam, lParam) ;
}
BOOL CALLBACK AboutDlgProc (HWND hDlg, UINT message,
WPARAM wParam, LPARAM lParam)
{HDC hdc;
switch (message)
{
case WM_INITDIALOG :
hdc=GetDC(hDlg);
TextOut(hdc,100,322,TEXT("your"),5);
ReleaseDC(hDlg,hdc);
return TRUE ;
case WM_COMMAND :
switch (LOWORD (wParam))
{
case IDOK :
DestroyWindow(hDlg) ;
idlg=0;
return TRUE ;
case IDC_cancel:
DestroyWindow(hDlg);
idlg=0;
return TRUE;
}
break ;
}
return FALSE ;
}

在CreateDialog后面加上ShowWindow(iDlg,SW_SHOW)试试Top

没理由啊！！！！！
你能不能把你的源程序发给我试一下，不可能的事啊！！！！！！
我用sdk写了这么久的程序，还没遇到这样的事！！！！

我已试过ShowWindow（iDlg，SW_SHOW)，仍不行Top
