Not use cskin provide skin, part use

The question now is: such as opening a form1, my code is normal test database records, popups no record, point to determine button, code is Close behind, and the normal can Close this window directly no problem, but if inherited cskin form, no other problem, the most simple but Close to Close the form code actually complains, tip can't access to destroy resource...


But if I turn off this code delay, also is to let the Form1 show 1 seconds without database records, or delay 1 second and then Close it is no problem, this is cskin compatibility issues?

Is now a little experience, don't want to see a second, a temporary solution is to change the height of this form to the screen seems to "see", but so much some timing code determine code to a close didn't seem necessary to completely...

Used under the guidance of leaders how to solve the problem?
