App not running after installation

Open Barley194 opened this issue 3 years ago • 11 comments

After installing this app, when I try to open it, nothing happens. Also there aren't any processes running in task manager.

Currently on windows 10 pro version 2004 (19041.572)

Same issue here. In the Windows Event Viewer I found a .NET error log with a stack trace:

It looks like the problem is happening on this line of code. The AreaForm constructor is being called, which calls InitializeComponent(), which executes the AreaForm_SizeChanged event handler, and all that happens before areaForm.Owner can be set.

Seems like adding some question marks in the event handler could fix the issue, for example:

(this.Owner as MainForm)?.SetMaximumX(maxWidth - this.Width);

Though I'm a .NET dev, I am certainly not a WinForms dev, so this definitely isn't my area of expertise.

Thank you for the tip.
