splash-screen

I'm writing a Windows Forms Application in C#.NET

On startup, the application displays a splash screen which is running in a separate thread. Whilst the splash screen is showing, the main application is initialising.

Once the main application has finished initialising, the main form of the application is displayed, and the splash screen still shows over the top.

Everything so far is as expected.

Then, the Splash screen is closed, which causes that thread to exit. For some reason, at the point, the main application windows gets sent behind all other open Windows, notably the Windows Explorer window where you clicked the .exe file to run the application in the first place!

What could be causing the windows to suddenly jump "behind" like this?

Dynamic Type to do away with Reflection

The dynamic type in C# 4.0 is a welcome addition to the language. One thing I’ve been doing a lot with it is to remove explicit Reflection code that’s often necessary when you ‘dynamically’ need to walk and object hierarchy. In the past I’ve had a number of ReflectionUtils that used string based expressions… >>> More
