Good Day,

We purchased the Pro version of the FC.Net controls to upgrade from the demo version as we are getting towards being able to release a product and have run in to a minor problem.

The PDF Export no longer seems to work.  Do I need to make some change(s) to the .licx file??  Or did I miss something else when upgrading the controls.

Just FYI, although it should not matter, we do have Adobe Acrobat Viewer 8 installed.

Thank you,
Jeff

No errors at all.  It simply hangs up at the call to pdfex.export.  The code is as follows:

           Try
               Dim pdfex As PdfExporter = New PdfExporter
               pdfex.AutoOrientation = False
               pdfex.AutoScale = MindFusion.Diagramming.Export.AutoScale.FitToPage
               pdfex.InvisibleItems = False
               pdfex.Margins = New System.Drawing.Printing.Margins(50, 50, 50, 50)
               pdfex.PageOrientation = PageOrientation.Landscape
               pdfex.PageSize = PageSize.Letter

               pdfex.Export(fc, savename)
           Catch ex As Exception
               Me.Cursor = Cursors.Cross
               MsgBox("File Save Error!", MsgBoxStyle.OkOnly + MsgBoxStyle.ApplicationModal + MsgBoxStyle.Exclamation, "Juno Error")
           End Try

The try catch block does NOT catch an error, it just seems to hang completely.  I can try to see if it times out somehow if you'd like.

I will email shortly.

Oddly, it worked correctly on ALL diagrams with the demo code, and seems to work with NONE of the diagrams with the registered control.

I will attempt to find the simplest version that causes an issue.

We are using the .NET 2.0.

I did some more testing, and it is NOT hanging up completely, it is just taking 45-60 seconds to create and save the PDF.

I am sending a zip file with the chart as XML, the chart as output by SaveToFile(name), and the PDF output.

I'm just wondering if there is some sort of assembly collision that I'm running in to here.

Check support email shortly.

The export takes about 10 seconds on our 1.6 Ghz test system. That's still very slow, so we have traced the Export method with the debugger and found that most of the time is spent on processing some large box images. The only explanation we can think of is that accessing the image data on your system is slower, but we don't have any idea why. Try using smaller images - it seems they are scaled down anyway when displayed in the boxes. Meanwhile we'll try exporting your diagram on other systems of ours to see if we'll get that bad performance.

We have tested exporting FIFRack_GA2062.jno to PDF from your application (using the dlls and viewer.exe from the bin folder), and it takes from 5 to 10 seconds on the systems we ran it. Do you get the 50 seconds delay only when running in debug mode, or also when running the .exe directly (or using Ctrl+F5 from VS)?

That image processing is required only when exporting images with transparent regions in them – the exporter creates some mask images used to create transparency in PDF. Since your images are opaque anyway, we could add a property that will let you disable the transparency processing, thus speeding up the export.

I just tested the export from the EXE and it is acceptably quick.

I don't understand the speed difference between the executable and the IDE with the registered version of the export because the demo version exported under the IDE in about the same amount of time that the registered version takes in the EXE.

Hmmmmm ... just something to ponder.  I will also be doing a couple of minor changes to our export routine so that the file selection dialog does not hang on the screen while the export is in process, I'll display an animation, or something, while the export is in progress.

Thank you,
Jeff

Thanks for checking for me.  Since you guys don't seem to see a difference in speed between the debug version and the exe version it leads me to believe that I still have some sort of dll problem, self induced of course.

I'll run through my project an clean up any dll mess that I may still have hanging.

Thanks again for the great product and support,
Jeff
