Here is a simple code fragment for windows 2.x. As has been stated
3.0 includes ES_PASSWORD for this function.

In the NORMAL dialog function for the dialog where the password
is requested, add the following entry:

	case WM_CTLCOLOR:	
		if(HIWORD(lParam) == CTLCOLOR_EDIT) /* an edits color */
		{
			HWND	hEdit = GetDlgItem(hDlg, MYPASSWORDEDIT);
			if(LOWORD(lParam) == hEdit) 
			{
				wReturnCode = (WORD)GetStockObject(WHITE_BRUSH);
				SetTextColor(wParam, RGB(255, 255, 255));
				return wReturnCode;
			}
		}
		break;

Note: you MUST return an hBrush if you process the WM_CTLCOLOR message.
This brush is used for the background of the control. Dont call 
UnrealizeObject for stock objects.
