PXV_Inst.ShowMsgBox(message, title, header, wHandle, flags) does not show the message box

[prasantha]

I created custom pane using pdf exchange editor sdk. I called the PXV_Inst.ShowMsgBox(message, title, header, wHandle, flags) method when anitem in that pane is deleted. I closed the opened pdf document if exists using
AxPXV_Control.Doc.Close() method.
Every call to PXV_Inst.ShowMsgBox(message, title, header, wHandle, flags) after closing the document does not show the message box.

I can see that it vanished as soon as it appears.
PXV_Inst.ShowMsgBox(message, title, header, wHandle, flags) call returtns 7 , that is its same as select "No" option .

So can anyone let me know know whats wrong here and how can I show the messge box after close the opened pdf document.

Thank You in advance

Hi prasantha.

I guess there might be problem with wHandle parameter. It depends how you get it. When you used:

wHandle = PXV_Inst.GetDlgParentWnd(doc)
or
wHandle = doc.ActiveView.Obj.GetFirstWndHandle();

then obtained wHandle is valid until doc is valid. Please check this case..

HTH.

Thank you for your respnse.

I have used the parent form's handle. like mainForm.Handle where mainForm is type of Windows form.
So this form is active always.

one more observation is , a the very first time the project is start up. no any pdf is opened. but when i tryto delete item, it shouws the error message. this error occured only after close the opened pdf document .

so I am not sure which handle should I use here

We couldn't reproduce that trouble with ShowMsgBox...
Can you provide a simple sample project to reproduce it on our side?
