托盤表徵圖及托盤菜單-問題及解決方案-編程-經驗

1.托盤菜單關閉不了-點擊空白處托盤菜單無法關閉

解決方案：在 PopupMenu 語句前加上 SetForegroundWindow Me.hwnd

例如：

if (LOWORD(lParam) == WM_RBUTTONUP)
{
HMENU hMenu = LoadMenu(This->Instance, MAKEINTRESOURCE(This->NotifyIconData.uID));
if (hMenu != NULL)
{
HMENU hSubMenu = GetSubMenu(hMenu, 0);
if (hSubMenu != NULL)
{
POINT pt;
LPCTSTR lpszText = NULL;
UINT EnableAPS =  MF_BYCOMMAND | MF_DISABLED | MF_GRAYED;
TCHAR MenuTitle[128];

if(g_bStart)
{
EnableMenuItem(hSubMenu, ID_APS_CONFIG, MF_ENABLED);

} else {

EnableMenuItem(hSubMenu, ID_APS_CONFIG, MF_DISABLED);
}
GetCursorPos(&pt);

switch (This->ApsDeviceState)
{
default:
case APS_STATE_DISABLED:
case APS_STATE_UNKNOWN:
LoadString(This->Instance, IDS_ENABLE_APS, MenuTitle, ARRAYSIZE(MenuTitle));
break;

case APS_STATE_ENABLED:
LoadString(This->Instance, IDS_DISABLE_APS, MenuTitle, ARRAYSIZE(MenuTitle));
break;
}

if (This->ApsDeviceState == APS_STATE_ENABLED ||
This->ApsDeviceState == APS_STATE_DISABLED)
{
EnableAPS = MF_BYCOMMAND | MF_ENABLED;
}

ModifyMenu(hSubMenu, ID_APS_ENABLE, MF_BYCOMMAND, ID_APS_ENABLE, MenuTitle);

EnableMenuItem(hSubMenu, ID_APS_ENABLE, EnableAPS);
SetForegroundWindow(hWnd);//沒有這句菜單不能自動消除
TrackPopupMenu(hSubMenu, TPM_LEFTALIGN | TPM_RIGHTBUTTON, pt.x, pt.y, 0, This->hMainWnd, NULL);
}
}
}
