Print preview not printing...

[Stanciu Vlad]

I have a print preview dialog that allways previsualates what is due to be printed. The previsualization work's fine, but the printing fails. I think that this may occur because at the printing algortihm the document.Print(); is called again. Is there any posibility to print directly the data previsualizated (into the control) without beeing necesary to recalculate (generate) it (through the document?

Hi You can do this by deriving a class from PrintController. When the dialog "prints" to generate the preview, save the metafiles produced. Then when the dialog "prints" to the printer, just return the saved images. ---------------------------- Be excellent to each other :) EasiReports[^] My free reporting component for WinForms.

Nicholas wrote an article on how to get the meta files of the preview and store them as images. You can find it here[^]. You will have to redirect the meta files into a new print job. Note that you nevertheless need another PrintDocument.Print cycle but you won't have to regenerate the output.

Thanks, exactly what I had to read before implementing an dirty method for obtaining the PageInfo from the preview control (reflection way). Didn't see the GetPreviewPageInfo() procedure. :)

If this is the case, (print preview is fine, print is not) then chances are you have some variables not reset somewhere, or set to the wrong value. I would suggest trying to figure out exactly what the problem is before "masking" the problem with another solution. Aaron

The problem was simple, I was doing a heavy print job, each page lasted for 1 sec to generate and there wore at least 10 pages. The request from the client was to be able to preview what is due to be printed. The solution I approched was this : into the print document I did a lot of heavy work ( the preview looked ok ) and in an inharited printPreviewDialog, on a print request, using reflection, I printed what was in the cache of the dialog (with out calling the document.Print() method again. I think that the dialog I designed can be usefull, so I intend to create an article based on it, but not now, currently I am time pressed. PS: thank you for your answer.
