Win32 API 如何显示非模态对话框啊？

[stonefire]

switch(LOWORD(wParam))
{
case IDM_OPENDLG:
if(hDlg)
DestroyWindow(hDlg);
hDlg=CreateDialog(hInst,MAKEINTRESOURCE (IDD_DIALOG1),hwnd, (DLGPROC)DlgProc);
break;
}
显示非模态对话框可是显示不出来，怎么回事了。
源程序是这样子的：

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

LRESULT CALLBACK WndProc(HWND,UINT,WPARAM,LPARAM);
BOOL CALLBACK DlgProc(HWND hwnd,UINT message,WPARAM wParam,LPARAM lParam);
HWND hDlg;
HINSTANCE hInst;
int WINAPI WinMain(HINSTANCE hInstance,HINSTANCE hPrevInstance,LPSTR szCmdLine,int iCmdShow)
{
static TCHAR szAppName[]=("hello, vc++");
static TCHAR lpszTitle[]=("My First program");
HWND hwnd;
MSG msg;
hInst=hInstance;
WNDCLASS wcex;

wcex.style = CS_HREDRAW | CS_VREDRAW;

wcex.lpfnWndProc = (WNDPROC)WndProc;

wcex.cbClsExtra = 0;

wcex.cbWndExtra = 0;

wcex.hInstance = hInstance;

wcex.hIcon = LoadIcon(NULL,IDI_APPLICATION);

wcex.hCursor = LoadCursor(NULL, IDC_ARROW);

wcex.hbrBackground = (HBRUSH)GetStockObject(WHITE_BRUSH);

wcex.lpszMenuName = NULL;

wcex.lpszClassName = szAppName;

HMENU hmenu;
hmenu=LoadMenu(hInstance,MAKEINTRESOURCE(IDR_MENU1));


if(!RegisterClass(&wcex))
{
MessageBox(NULL,TEXT("This program reguire Windows NT!"),szAppName,MB_ICONERROR);
return 0;
}

hwnd = CreateWindow(szAppName,TEXT("The hello program"),WS_OVERLAPPEDWINDOW,
CW_USEDEFAULT,CW_USEDEFAULT,CW_USEDEFAULT,CW_USEDEFAULT,NULL,hmenu,hInstance,NULL);

if(!hwnd)
{
MessageBox(NULL,TEXT("can't creat windows"),szAppName,MB_ICONERROR);
return 0;
}

ShowWindow(hwnd,iCmdShow);
UpdateWindow(hwnd);
while(GetMessage(&msg,NULL,0,0))
{
if(!IsDialogMessage(hDlg,&msg))
{
TranslateMessage(&msg);
DispatchMessage(&msg);
}
}
return msg.wParam;
}
LRESULT CALLBACK WndProc(HWND hwnd,UINT message,WPARAM wParam,LPARAM lParam)
{
HDC hdc;
PAINTSTRUCT ps;
RECT rect;
switch(message)
{
case WM_COMMAND:
switch(LOWORD(wParam))
{
case IDM_OPENDLG:
if(hDlg)
DestroyWindow(hDlg);
hDlg=CreateDialog(hInst,MAKEINTRESOURCE(IDD_DIALOG1),hwnd,(DLGPROC)DlgProc);
break;
}
case WM_PAINT:
hdc=BeginPaint(hwnd,&ps);
GetClientRect(hwnd,&rect);
DrawText(hdc,TEXT("hello VC6.0"),15,&rect,DT_SINGLELINE|DT_CENTER|DT_VCENTER);
EndPaint(hwnd,&ps);
return 0;
case WM_DESTROY:
PostQuitMessage(0);
return 0;
}
return DefWindowProc(hwnd,message,wParam,lParam);
}
BOOL CALLBACK DlgProc(HWND hwnd,UINT message,WPARAM wParam,LPARAM lParam)
{
switch(message)
{
case WM_INITDIALOG:
return 1;
case WM_COMMAND:
switch(LOWORD(wParam))
{
case IDOK:
if(hDlg)
DestroyWindow(hDlg);
EndDialog(hDlg,0);
return 1;
}
case WM_CLOSE:
if(hDlg)
DestroyWindow(hDlg);
EndDialog(hDlg,0);
return 1;
}
return 0;

}

在CreateDialog后加上
ShowWindow(hDlg, SW_SHOW);
