exception System.Reflection.TargetInvocationException error

Question

I m trying to run an older vb.net code but it breaks with this error (exception System.Reflection.TargetInvocationException). Here's the tracelog:

   Source="mscorlib"   StackTrace:

   à System.Runtime.Serialization.ObjectManager.CompleteISerializableObject(Object obj, SerializationInfo info, StreamingContext context)

The line #160 performs this task Me.ImageList1.ImageStream = CType(resources.GetObject("ImageList1.ImageStream"), System.Windows.Forms.ImageListStreamer)

I think the error is due to this line cause when I comment it, everything runs well. How can I fix this?

Answer 1

This is the expression within the statement which is causing the problem

resources.GetObject("ImageList1.ImageStream")

Based on the stack trace it appears there is something wrong with the ImageList1.ImageStream resource. It exists but the deserialization code isn't able to handle it properly.

It's hard to say without seeing the actual resource what the problem is. My first step would be to simply load up the resource in Visual Studio and see if it's corrupted. If not try replacing it with a stock image list and see if the problem goes away (would indicate a bad resource)
