hello everyone. In recent days, I have met some new problems. I want to get .mdf format file ,then I look up help manual, it said I can export .mdf format file by Export function. I write the script "\$doc->Export("chuanzhi.mdf");", but I failed and got the error message "This document doesn't have any exporters for extension mdf (function/property "Export") ".How can I get .mdf format file by script. If you have some idea please share it here, thank you!
