Additional information: Exception has been thrown by the target of an invocation.

Hi,
I have .dll with Form and ImageList component,
when I'm making instance, I got execption:

An unhandled exception of type 'System.Reflection.TargetInvocationException'
occurred in mscorlib.dll
Additional information: Exception has been thrown by the target of an
invocation.

at line:
this.imglToolBar.ImageStream =
((System.Windows.Forms.ImageListStreamer)(resources.GetObject("imglToolBar.I
mageStream")));

What is wrong?

Those kind of errors are difficult to troubleshoot.

Put a try/catch around the code which makes the instance, and examine the
InnerException property of the TargetInvocationException. It should lead
you to a better description. My guess is that your GetObject call is
returning Null for some reason, and the cast is failing.

Best Regards,

Any other suggestions?

None from me. Did you try the InnerException thing, and not get any
meaningful information?
