You cannot do it from VFP6 DLL. COM DLL does not allow user interface elements and REPORT FORM ... to printer causes the box "Printing... " to appear. In this case you will have to use COM EXE. Or run your DLL under later version of VFP that has NODIALOG clause in REPORT FORM command. - Correction: it is not implemented yet..." :)

>Some guys at work are having trouble printing from a DLL they created in VFP 6.0. The code works fine when running from VFP but when running from the DLL an error 'user interface not allowed' is generated. They are using a command like:
> report form x noconsole to printer

>I have not yet been fortunate enough to need to print from within a DLL. Why would they be getting this error and what is necessary to overcome the problem?
