StackTraceException on program start

hi all,

i'm currently building an order management software based on a mysql
database (using mysql.net-connector 1.0.4) for our company. since i'm still
at the beginning with the application, it has 4 forms and is linked to a own
custom usercontrol (a combobox like control, but without dropping down a
list box, it drops down a datagrid).

when i'm trying to start the application it compiles correctly and when it's
painting the main window on the screen a JIT-error window appears with a
StackTraceException. if i click "continue" i can use my app without any
problems.

in my "Function Main()" i try/catched the "Application.Run(mainForm)"
clause, but it doesn't catch this error. i also enabled JIT-debugging in my
machine.config file, but i'm not able to catch and trace this error, yet.
if i'm running the app step-by-step, the error occours on the "End Sub"
clause of my Form_Load Event.

can anyone help me?
thanks a while...

bye

of course the error is a StackOverflowException... the other is garbage...

NetRacer,

Which means an endless loop, what can be is that you call in an event the
same event. (Indirect by instance when you change the index of a combobox
in a indexchangeevent than it will be called again and again and again). My
solution is than to remove the eventhandler as first statement and add it
again as last.

I hope this helps,

Cor

Yeah you were right. But why can't i catch this error like others?
I had to use Windbg with the SOS library to trace the error back.

In my custom usercontrol i wrote "Me.OnEnter(e)" instead of
"MyBase.OnEnter(e)" in the overwritten method, so it became recursive...

however thx a lot,
netracer
