Closing a child form in an MDI application - Problem

[Ling Woo]

Hello,

In my MDI application when a new child window is opened I perform some
inital processing in the form load event of the child form. If an exception
is thrown I want to close down the form, however I am getting the following
error when I try and do this from the child form.
"An unhandled exception of type 'System.InvalidOperationException' occurred
in system.windows.forms.dll"

"Additional information: Cannot call Close() while doing CreateHandle()."
+++++++++++++++++++++++++++++
SAMPLE CODE BELOW
+++++++++++++++++++++++++++++
private: System::Void frmDisplay_Load(System::Object * sender,
System::EventArgs * e)
{

try
{
//Perform processing
}

catch (Exception* e)
{
MessageBox::Show("Error");
this->Close();
}

}//end frm_load

I have a question for you!
Do you know how to program in Native Windows Code?
