Dear tdloc,
Thanks for your inquiry.
This problem is refer to multithreading not our component.
However, I recommend you use BeginExport and EndExport events.
And I recommend you have look at this article. http://www.codeproject.com/KB/cpp/BackgroundWorker_Threads.aspx

Hi,

I have used BeginExport and EndExport events to set the progress bar min value and max value but I don't know how to get the current value of Spire.DataExport to update to the progress bar.

Please help me.

Thanks for your help.

Dear tdloc,
Thanks for your inquiry.
Use BeginExport event to initial the progress bar.
I don't think you should get the current value to do so, just show the progress is running.
Use EndExport event to show something like export complete.

Dear Justin Weng,

I found that DataExport has the ExportedRecord event (Occur after the export of each source record).

And with this event I have made the progress bar works successful with the percent finished :D.

This is really a great component. I hope Spire.DataExport will be improve even more better.
Thanks for your help.
