error on CreateDialog

The error code is 6 with GetLastError£¨£©£¬
First i registered a WNDCLASS£¬then I create a dialog¡£
But it failed¡£
My intent is to add an icon for the dialog in a dll.
Someone can help me?
Thanks.
Code:
wc.style = CS_HREDRAW | CS_VREDRAW ;
wc.lpfnWndProc = (WNDPROC)WndProc ;//callback procedure
wc.cbClsExtra = 0 ;
wc.cbWndExtra = DLGWINDOWEXTRA ;
wc.hInstance = tmp_hModule ;
//dllmain input handle when attach process
wc.hIcon = LoadIcon(tmp_hModule, MAKEINTRESOURCE(IDI_ICON1));
wc.hCursor = LoadCursor (NULL, IDC_ARROW) ;
wc.hbrBackground = GetStockObject (LTGRAY_BRUSH) ;
wc.lpszMenuName = NULL ;
wc.lpszClassName = szAppName;
//defined as TCHAR szAppName[] = TEXT("OPERATIONPANEL");
if(!RegisterClass(&wc)) return FALSE ;

hwnd=CreateDialog(tmp_hModule,MAKEINTRESOURCE(IDD_TABLEDLG),0,WndProc);
if(hwnd==NULL)
{
error=GetLastError();
wsprintf(str,L"error=%d",GetLastError());
MessageBox(NULL,str,L"CreateDialog",MB_OK);
return FALSE;

To create a dialog you don't have to register a class. Your class will not
used for the dialog, anyway.

You can actually use a custom class with a dialog, BTW.

Error 6 is invalid handle. Perhaps the hinstance that the OP specified is
invalid..?

I believe you have to change the .rc file to add the CLASS item in the
dialog resource. See

http://support.microsoft.com/?id=251059
How to provide your own Window class name for an MFC dialog box

BTW, this is not the correct newsgroup for SDK questions. Next time
try microsoft.public.vc.mfc newsgroup.
