Question

I am writing an application in C# that uses forms. This is my first app written in C# so I am very much a beginner.

This is the problematic code

if (tabControl1.InvokeRequired)
{
    stringDelegateC sdc = new stringDelegateC(manageCode);
    this.Invoke(sdc, new object[] { text });
}
else
...

The variable text is always a string in the format: “PM” followed by a number. It works fine most of the time but when text is “PM11020” I get System.Xml.XmlException thrown with the message “An error occurred while parsing EntityName. Line 5, position 25.”. The exception is thrown by this.Invoke(sdc, new object[] { text });

If text is “PM11120”, it works fine.

I am very confused by this, I don’t know what XML has to do with anything.

Answer 1

That XML exception is probably thrown by the manageCode method and has nothing related to Control.Invoke.
