Cause of System.FormatException and System.ArgumentException

[scott.clark]

using AdvancedHMI v3.97c  Visual studio 13

I am seeing these exceptions in my Debug Output Window.  Any suggestions on how to track them down.

A first chance exception of type 'System.FormatException' occurred in mscorlib.dll
A first chance exception of type 'System.ArgumentException' occurred in System.Drawing.dll

Thanks!

While waiting for Archie to respond, you could always check examples listed on MSDN for possible causes:

What controls do you have on your form?

When the output windows shows an exception, it typically means an exception occurred, but was trapped and handled, so it will not dump the application.

This may give you some idea.....

It looks like the BasicIndicator is the only AdvancedHMI visual control. I will test it to see if I get the same exceptions showing in the output window.

I'm not seeing any of these exceptions with a BasicIndicator. Are you using Try-Catch any where in your code?
