Hide App button from TaskBar when it goes to Systray icon

[m.losinno]

This parameter is ignored the first time an application calls ShowWindow, if the program that launched the application provides a STARTUPINFO structure. Otherwise, the first time ShowWindow is called, the value should be the value obtained by the WinMain function in its nCmdShow parameter.

Maybe not the prettiest solution, but it works.
You should remove the WS_EX_TOOLWINDOW style again when removing it from the tray.

      lError = Shell_NotifyIcon(NIM_ADD,ADDRESS(gNotifyIconData))
      ShowWindow(wTest{Prop:Handle},SW_HIDE)
      lStyle = GetWindowLong(wTest{PROP:Handle}, GWL_EXSTYLE)
      lStyle = BOR(lStyle, WS_EX_TOOLWINDOW)
      ret# = SetWindowLong(wTest{PROP:Handle}, GWL_EXSTYLE, lStyle)
      ShowWindow(wTest{Prop:Handle},SW_SHOW)

Hope it helps…
