[RESOLVED] FindWindowEX question

[DeepT]

I am looking to find a particular dialog box. I used the Spy tool and it gave me the class name for this dialog box as "#32770 (Dialog)". If I use FindWindowEx(NULL, NULL,"#32770 (Dialog)", NULL), I always get a null in return, however, FindWindowEx(NULL, NULL,NULL, NULL) actually lets me iterate through the windows and find the window I am looking for.

I just want to make sure I do not find a similarly named window (unlikely, but possible). Anyway here is a more complete code fragment of my search:

void WLanConfig::SupGUIWatch()
{
	vector<char> Buffer;
	Buffer.resize( 1025, 0 );

	while ( ( false == FoundSupGUI ) && ( false == AbortWait ) && ( false == KillSupGUIWatch ) )
	{
		HWND h1 = NULL, h2 = NULL;

		// This finds the window I am looking for although I need to iterate through a lot of windows.
		h1 = FindWindowEx(NULL, h2,NULL, NULL);

		// This does not, the class name was gotten by using DevStudio's spy tool
		// h1 = FindWindowEx(NULL, h2,"#32770 (Dialog)", NULL); // Always returns NULL
		while ( h1 != NULL )
		{
			int Len = (int)SendMessage(h1, WM_GETTEXT, 1024, (LPARAM)&Buffer[0]);

			if ( Len > 2 )
			{
				CString MatchBuff;
				MatchBuff = &Buffer[0];
				if ( -1 != MatchBuff.Find( "Windows Security" ) )
				{
					Logger::Log.Format("Found the supplicant GUI \"%s\"", &Buffer[0] );
					LOGQ( 1 );

					GetWindowRect( h1, &SupGUIWindowRect );

					FoundSupGUI = true;
					break;
				}
			}

			h2 = h1;
			h1 = FindWindowEx(NULL, h2, NULL, NULL);
			// h1 = FindWindowEx(NULL, h2, "#32770 (Dialog)", NULL);
		} // while ( h1 != NULL )

		Sleep(50);
	} // while ( ( false == FoundBubble) && ( false == AbortWait ) )


}

I want to know why specifying the class name fails in this case. I does look like a strange name, and I am guessing Spy isn't telling me the accurate name. If this is the case, how can I find the accurate name of a window's class?
