这是我大概的程序（第一个窗口的创建部分），窗口1既没有背景，从别的窗口切换回来还会闪烁。
static void _cbDialog1(WM_MESSAGE * pMsg);
static void _cbDialog1(WM_MESSAGE * pMsg)

WM_HWIN hItem;
int NCode;
int Id;
hItem = pMsg->hWin;
GUI_MEMDEV_Handle hMem0;
hMem0 = GUI_MEMDEV_CreateEx(0, 0, 480, 272, GUI_MEMDEV_HASTRANS);
switch (pMsg->MsgId)
{
case WM_INIT_DIALOG:
WM_SetCreateFlags(WM_CF_MEMDEV);
GUI_MEMDEV_Select(hMem0);
GUI_DrawBitmap(pBmp[1], 0, 0);
// 初始化按钮控件
hItem=WM_GetDialogItem(pMsg->hWin,ID_BUTTON_2);

break;
