Nothing executes after "Object.DoVerb"

[Erickc]

Hello,

I have problems with PDF-XChange Viewer ActiveX Control in a PowerBuilder 12.5.2 client application.

When I call the doVerb method, it works but any instruction that would come after in my code isn’t executed. It’s just as if PowerBuilder lose control.

For example, a function used to rotate the displayed document :

Code: Select all

Function of_rotate (asrotation)

Any        aIn, oOut, oOut2
long       l_nb_pages

Ole_PDF.Object.SetProperty( "Operations.RotatePages.RangeType", '1', 0)
Ole_PDF.Object.SetProperty( "Operations.RotatePages.Direction", asRotation, 0)

Ole_PDF.Object.GetProperty("Documents.Count", ref oOut2, 0);
l_nb_pages = oOut2

SetNull( aIn )
SetNull( oOut )
Ole_PDF.Object.DoVerb("Documents[0]", "RotatePages", aIn, oOut, FlagNoUI )

i2 = 2
Return( Success )

On a call to of_rotate('ClockWise') at a button press, the document is rotated be the instruction i2 = 2 doesn’t execute and there is no Return(Success).

But I can press again the same button to rotate again the document.

I have the same result with another function used to summarize annotations :

Code: Select all

Any        dataIn, dataOut
SetNull( dataIn )
SetNull( dataOut )

ole_pdf.Object.SetProperty("Operations.SummarizeAnnots.Output.TXT.FileName", ‘toto.txt’)
ole_pdf.Object.SetProperty('Operations.SummarizeAnnots.Output.TXT.FolderName', ‘C:\Temp\’)
ole_pdf.Object.DoVerb("Documents[0]", "SummarizeAnnots", dataIn,  dataOut,  2)

i1 = 1

return(Success)

summarizeAnnots works but neither 1 = 1 or retrun(Success) execute.

When traced in the debugger of PowerBuilder, everything stops after doVerb.

I know PowerBuilder is not really used a lot but maybe someone could gives me some general hints.

Thank you !

Hello Eric,

I have asked my colleagues from the dev team to take a look, but we might not have people with vast experience with PowerBuilder.
While the guys are looking at this - can you try our Full Demo projects - do these work correctly for you?

Thank you Stefan,

I will try the Full Demo project and let you know if I get more success with doVerb.

Cheers,
Eric

Thanks Eric,

Let us know how your tests go!

Hello Stefan,

A quick note to let you know that probably more than likely, the doVerb problems were caused by some PowerBuilder quirks that we were finally able to get around.

Best regards!
