I have in a form a button that issues a SQL Retrieval command [ BO_Emp.FillAll() ] to populate the form. So, the form is displayed and if the button is clicked, data is retrieved into the form.

Doing this - in debug mode - caused a "LoaderLock" exception that said:

"..is attempting managed execution inside OS Loader lock. Do not attempt to
 run managed code inside a DllMain or image initialization function
 since  doing so can cause the application to hang."

Searching the www, I found the following:

"From the Debug menu, find the exceptions,
The under Managed exception, Remove the LoaderLock exception, this will prevent that exception..."

Doing this made the thing to work ok.

Don't quite know if one should do something here...

Cheers,
Kari
