Hi,

Sometimes when I execute this.Opacity = 0; in the Main thread I get
the below exception:

System.ComponentModel.Win32Exception was unhandled by user code
Message="Not enough storage is available to process this command"
Source="System.Windows.Forms"
ErrorCode=-2147467259
NativeErrorCode=8
StackTrace:
at System.Windows.Forms.Form.UpdateLayered()
at System.Windows.Forms.Form.set_Opacity(Double value)
at eV.PpvForm.makeNotVisible()
at
System.Windows.Forms.Control.InvokeMarshaledCallbackDo(ThreadMethodEntry

System.Windows.Forms.Control.InvokeMarshaledCallbackHelper(Object obj)

System.Windows.Forms.Control.InvokeMarshaledCallback(ThreadMethodEntry
tme)
at System.Windows.Forms.Control.InvokeMarshaledCallbacks()


I checked disk space and swap file utilization, didn't see anything
that could cause a "Not enough storage" error.

In my application the user sees either the Main thread Form or
another Form named "menu". There is a 3rd thead that uses the 2 Forms
that does most of the work of the program. Both the Main Form and the
"menu" Form run in the identical location and are identical in size, I
don't want the user to know there are 2 Forms. When viewing the
"menu" Form minimizing the Main Form doesn't work, so I am trying
Opaity=0. The Main Form and the "menu" Form are totally different, I
don't want to try to force the 2 together, it would make some really
ugly code. Why am I getting the above exception? Is there a better
way to hide the Main Form?

Thanks,
Mark
