Doing conversion synchronously

Is there a way to work with the controll synchronous (currently asynchronous)? We will need to convert multiple xa multiframe images and need to continue the process only when all have been converted.

One way to do that is to implement the Complete event of convert control and define a Boolean variable describes the status of the conversion like this:
+=====================================================================+
bool done;
private void button1_Click(object sender, EventArgs e)
{
done = false;
convertCtrl1.SourceFile = "IMAGE1.dcm";
convertCtrl1.TargetFormat = TargetFormatType.AVI;
convertCtrl1.TargetFile = "result.avi";
convertCtrl1.StartConvert();
           
while (!done)
{
Application.DoEvents();
}
}
private void convertCtrl1_Complete(object sender, EventArgs e)
{
done = true;
}
