//way second option is if u want to pass a parameter in Function .

// note you can not access any winform control directyly if want to access a TextBox or Combobox or //something else then you need a delegate to perform this operation. for example
SetControlPropertyValue(lblProgress, "Text", value);ClearGroupBoxContent(groupBox1);
