>I have a modeless form. When the user selects an 'Execute' button on the form how to prevent the user from then closing the modeless form while the method is executing? The 'Execute' commandbutton does not close the form at completion. But I do not want the user to try to close the form either in the middle of the process as it may be long running (I am displaying a status indicator). Thanks.

Well, I was thinking how to disable this x (controlbox). I thought this topic could have been discussed in the Russian forum, but the only topic I found was this:

(see the code to add items to the system menu).

Not helpful for this question, but just in case...
