backgrounworker

[Guest Vergassivellaunus]

I inserted a backgroundworker form in my project.

 

My intention is to execute a long time evaluation without blocking the graphic interface.

 

These 2 routines should do the job:

 

Public Sub BackgroundWorker1_RunWorkerCompleted(sender As Object, e As ComponentModel.RunWorkerCompletedEventArgs) Handles BackgroundWorker1.RunWorkerCompleted

 

End Sub

 

Public Sub BackgroundWorker1_DoWork(sender As Object, e As ComponentModel.DoWorkEventArgs) Handles BackgroundWorker1.DoWork

x=math_evaluation() 'x is an array

End Sub

 

When math_evaluation is completed, RunWorkerCompleted should be triggered, but this does not happens.

 

If I use in dowork not a function but a sub, it works:

 

Public Sub BackgroundWorker1_DoWork(sender As Object, e As ComponentModel.DoWorkEventArgs) Handles BackgroundWorker1.DoWork

math_evaluation()

End Sub

 

This is ok.

 

What is wrong?
