error creating window handle
I've tried calling an mdi child from an mdi child form.
Here is the code:
Code:
Dim afrmPrintTransaction as frmPrintTransaction = frmPrintTransaction.Instance
afrmPrintTransaction.connectionString=myconnString 'write only property use to pass the connection string
conn.close()
With afrmPrintTransaction
.MdiParent=frmMainForm
.Show()
.Focus 'the error appears in here
End With
but when i tried to run it. I get the error "error creating window handle"
I've also tried to putting the code from the mdi parent and call it through the mdi child. but instead i get the error "object reference not set to an instance of an object"
