In Windows 7, does Alt+Tab now only display windows that have a taskbar button? Windows without a taskbar button are not showing up in the Alt+Tab list.
This is somewhat annoying to say the least. Visible dialogs without a taskbar button obviously cannot be selected via the taskbar, and they can't be selected via Alt+Tab either?
The application in question is a legacy (pre-Vista) app that creates a simple window without a taskbar button. Windows XP displays it in the task switcher. Windows 7 does not.
FindWindow
andPostMessage
to send this window theWS_EX_APPWINDOW
message. This forces the window onto the taskbar.
