Is that calling a second thread in a first running thread is invalid? can you please suggest a solution to remove exception

Well the web browser control will have been created on the main UI thread and so if you're trying to access it from the DoWork event of the BackgroundWorker this will lead to a cross-thread exception. You'll therefore need to marshal the web browser code back to the UI thread which can be done as follows: this.Invoke(new MethodInvoker(delegate() { // put existing web browser code in here }));
