WinForm: Loading form for InitializeComponent method

Question

We have a Windows Form application for our fingerprint scanning for time keeping and it takes too much time for just initializing the control for the finger print scanning, around 5 to 10 minutes. So we need to create a loading form so that users will know that the application doesn't hang and they need to wait, but the cause of the long running process was inside the InitializeComponent() method from the initialization of the form.

My question is, how can I move the InitializeComponent() method to another thread so that I can show a loading form while initializing the form where the biometrics scanner control is, because it creates an error when accessing a UI control from another thread other than the main thread?

My code is in C#, Framework 2.0, build in Visual Studio 2008.

Please help, thanks in advance.

You can remove your control for the finger print scanning from the visual designer and create this control from the code using an additional background thread and writing a progress information during this process.

The links you gave are more for updating the UI in other thread. But my problem is for **initializing** the UI in other thread. – John Isaiah Carmona Sep 17 '12 at 06:19

You can find your InitializeCompoent(); method in yourForm.designer.cs, and from there you can modify it.
