Passing a string through a BackgroundWorker's RunWorkerAsync
I have a Bacground Worker where it needs a string. I have put the string in the RunWorkerAsync function but when I try to cast the sender variable back to a string with the following line..
Calling method:
String^ arg=this->GenerateArg();
MessageBox::Show(arg);
this->threadPleaseWait->Ru
casting Method
String args = dynamic_cast<String^>(send
arg is a String^, I get what I expect in the message box but when casting the 'args' value is null

This solution is only available to members.
To access this solution, you must be a member of Experts Exchange.
HAve you tried to use safe_cast instead ?
BTW, sender is BackgroundWorker itself. You need to cast it to BackgroundWorker and use inside of DoWork function.
