P/Invoke and ChooseFont (Comdlg32.dll)

Mister Goodcat wrote a good article a little while ago about using P/Invoke in Silverlight 5 to display the native font chooser dialog with the ChooseFont function.

Windows 7-style Notification Area Applications in WPF: Part 6 (Notify Icon Position: Pre-Windows 7)

View source on GitHub. In Part 2 of this series I demonstrated how to use the Shell_NotifyIconGetRect function to find the position of a notify icon. This function is new to Windows 7, however, and we must find a different solution for earlier versions of Windows. This turns out to be quite difficult. A post…

Windows 7-style Notification Area Applications in WPF: Part 2 (Notify Icon Position)

View source on GitHub. You may have noticed that the notification area applications in Windows 7 (Volume/Power/Network/Action Centre) appear centred above their icon. I wanted Keiki to do the same; the current version is hardcoded to sit in the bottom right of the screen, which causes a few problems: The taskbar position is not taken…
