NIF_SHOWTIP top-level constant Null safety
Windows Vista and later. Use the standard tooltip. Normally, when uVersion is set to NOTIFYICON_VERSION_4, the standard tooltip is suppressed and can be replaced by the application-drawn, pop-up UI. If the application wants to show the standard tooltip with NOTIFYICON_VERSION_4, it can specify NIF_SHOWTIP to indicate the standard tooltip should still be shown.
const NIF_SHOWTIP = 0x00000080;
