Window Placement and Border Snaps

[mike-ward]

In Windows 8.1 when one can size a window and as it gets near a screen edge, it snaps the window. Problem is, the window position is not "remembered" when the application is closed and reopened. It seems that window position is not captured whenever one of these "snap" operations occurs.

Steps to reproduce:

1. Open Markdown Edit (https://github.com/mike-ward/Markdown-Edit/releases/download/v1.3.2/MarkdownEditSetup.msi)
2. Click and drag bottom window border to bottom edge of screen and release mouse
3. Window will snap to top and bottom edges
4. Close program and reopen

Expected: Window should return to same position and size when it was closed.

Actual: Window opens at previous window and size before resizing (snapping) operation.

I've done some research on this issue and it appears to be a hard problem to solve. Something about GetWindowPlacement not receiving the correct coordinates.

How do you persist the window location between application restarts?

Sorry, should have mentioned I'm using MahApps SaveWindowPosition="True" attribute on the main window which is a MetroWindow.

windows GetWindowPlacement method...

There lots of questions regarding this at StackOverflow. The general advise is to call GetWindowRect():

The workaround is to call GetWindowRect() to get the actual window coordinates and copy them over the bad coordinates in WINDOWPLACEMENT::rcNormalPosition.
