winforms

We only want one instance of our app running at any one time. So on start up it looks to see if the app is running and if it is, it calls SetForegroundWindow on the Main Window.

This is all good and well ... for the most part..

When our app starts up it will show a Splash screen and a Logon form. Both of these forms have ShowInTaskBar = false.

Because of this, if you try to start up another copy of the app when the Logon form is showing, that Logon form is not brought to the front!

Especially as the user cant see anything in the taskbar as well, all they figure is that the app is duff and cannot start. There is no indication that there is another instance running.

Is there any way around this problem?

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
