The automation of OCC document is very useful to manipulate the OCC document test modules or test object parameters without opening the test object window. Making of custom dialog is very useful because we can change the target parameters in the test object without opining it. In few lines of codes, we can could get the test object parameter value like substation name or address, relay type, serial number & etc. and display it into a textboxes then change the textbox values and sent it back to the test object.
