Hi,

i think you want your form not showing for a while!?

Did you use fromTwo.close() for this!?

this Method will remove the form Object from your memory and its normal when you can't access later!
Instead use

formTwo.hide()
formTwo.show()

i hope i couls help you

Christian is alright ... also note that in order to reopen closed form (if you want to avoid hide/show methods) you should declare the form object ones again / Dim FormTwo As New Form2 or if it's public variable you could do that as it follows:
FormTwo = new Form2
FormTwo.Show()


Cheers
