OutOfMemoryException

[newtovbnet]

What might be the cause for the following during run time? Am I not freeing something?

------------------------
An unhandled exception of type 'System.OutOfMemoryException' occurred in system.windows.forms.dll

Additional information: Error creating window handle.

What is your app doing when the error is encountered?

You crack me up!

Oh, the problem is gone now... hmmm ... don't know why, I keep hitting ctrl-z to delete whatever I changed earlier, I guess that helps...

I loaded my main page with no problem, then when I tried to bring up a child screen, it died loading this child page. The routine it died at was a button click sub.

Anyways, do I need to worry about memory problem?

Anyways, do I need to worry about memory problem?

With unmanaged code you should always be sure to dispose objects so they can be released back to open memory. Otherwise, you can fill up the RAM leaving no room for anything else.

So when I close the form, I should always dispose() for OleDbConnection, dataset, datatable etc?

[circuits2]

Closing the form will automatically dispose it's objects, but if you have a sub that may run several times throughout the life of the form, then you need to make sure the objects in the sub are properly disposed.

I see. Thanks.
