WM_SendMessageNoPara(_hDialog[0],WM_PAINT);
这个函数 具体用法，以及用了之后发生了什么样的事情
比如：
我有一个任务，想让我的回调函数里面的 WM_PAINT 这个消息里面的一些自己绘制的矩形框的颜色主动刷新，每个矩形框对应了一个变量，变量值是实时更新的。 现在又一个问题 就是 变量变化了 矩形框的颜色不变
static void uctsk_Fresh(void)
{
for(;;)
{
OSTimeDlyHMSM(0, 0, 30, 0);
FreshTask();
//
}
}
void FreshTask (void)
{
WM_SendMessageNoPara(_hDialog[0],WM_PAINT);
}
_hDialog[0] 就是下面这个回调函数的句柄
static void _cbDialog_A(WM_MESSAGE * pMsg) {
int Id, j, i,NCode;
//char **p=SHOW[CH_E_Chang];
WM_HWIN hItem,ahButton;
hDlg_A= pMsg->hWin;
switch (pMsg->MsgId) {
case WM_PAINT:
