Hi, I need to print some local rdlc reports without previewing it and without any print dialogs. I found a code, that makes it, but however, it creates emf files on disk. I need to make some changes to the code, so that it would work without those files (no files written on disk). The solution with emf files is here: http://msdn.microsoft.com/en-us/library/ms252091.aspx

        dataSet.ReadXml(@"..\..\data.xml");

PrintDocument class has a property called PrintController which has a property called IsPreview

But it does not solve the problem with exported files. It only allows the printing with no preview, which is fine, thank you. But the main problem is still there. How do I print a report without exporting it to emf files on disk?

Just change the CreateStream to use a MemoryStream instead of a FileStream.  

If the report is large, then you might run into memory problems.  You can also print to a file, and when the Report is Disposed delete the file as well.
