Method CreateTrayIcon

source/script.cpp:1003–1023

void Script::CreateTrayIcon()
// It is the caller's responsibility to ensure that the previous icon is first freed/destroyed
// before calling us to install a new one.  However, that is probably not needed if the Explorer
// crashed, since the memory used by the tray icon was probably destroyed along with it.
{
	ZeroMemory(&mNIC, sizeof(mNIC));  // To be safe.
	// Using NOTIFYICONDATA_V2_SIZE vs. sizeof(NOTIFYICONDATA) improves compatibility with Win9x maybe.
	// MSDN: "Using [NOTIFYICONDATA_V2_SIZE] for cbSize will allow your application to use NOTIFYICONDATA
	// with earlier Shell32.dll versions, although without the version 6.0 enhancements."
	// Update: Using V2 gives an compile error so trying V1.  Update: Trying sizeof(NOTIFYICONDATA)
	// for compatibility with VC++ 6.x.  This is also what AutoIt3 uses:
	mNIC.cbSize = sizeof(NOTIFYICONDATA);  // NOTIFYICONDATA_V1_SIZE
	mNIC.hWnd = g_hWnd;
	mNIC.uID = AHK_NOTIFYICON; // This is also used for the ID, see TRANSLATE_AHK_MSG for details.
	mNIC.uFlags = NIF_MESSAGE | NIF_TIP | NIF_ICON;
	mNIC.uCallbackMessage = AHK_NOTIFYICON;
	mNIC.hIcon = mCustomIconSmall ? mCustomIconSmall : g_IconSmall;
	UPDATE_TIP_FIELD
	if (!Shell_NotifyIcon(NIM_ADD, &mNIC))
		mNIC.hWnd = NULL;  // Set this as an indicator that tray icon is not installed.
