ListBox Items

Illegal Operation22-Nov-09 18:22

Illegal Operation

22-Nov-09 18:22

Hi!

I have a TextBox with a Button and a ListBox. I will type in an email address and click the button and the email address will be added to the listbox. Simple enough.

My question is this:

How would I go about serializing the ITEMS in the ListBox to an XML file? I know how to create the XML file using the SOAPFormatter but I only serialize the first item in the listbox. I need to serialize all of the items in the listbox.

Thank you!

Hi,
I am working on retrieving emails from mail servers(like gmail,etc..) using pop3 and imap. I need to know, is there any other way to do this without using these protocols.

Thank you.

I don't think that's possible; you are essentially asking to modify framework types.

That's generally not possible. But in most cases we can derive new types from them (when they are not sealed). In this case you could perhaps derive a custom grid type from DataGridView, a column type from DataGridViewColumn, and have your custom grid use your custom column for unbound columns. That way you can add whatever properties you like and associate your own designer class and type editors with it if you wish.

It clearly saying that some object is not initialize. Please go thorough the code and debugged it. Or show us the code.

Its giving the exception in

XlWB = XlApp.Workbooks.Open(workbookPath,0,false, 5, "", "", false, Excel.XlPlatform.xlWindows, "", true, false, 0, true, false, false);

and Exception is:

An unhandled exception of type 'System.NullReferenceException' occurred in testexcelwrite.exe

Additional information: Object reference not set to an instance of an object.

I think you need to initialize XlWB
