[junaidahmed]

I have an Pdf file with four page.I would like to scroll last page when I open pdf file in "pdfviewer".I have tried below code but its not working.Please check below code and attached file for your reference.

Sub LoadPdfVile(StrFile As String)
    
    If pdfv.IsInitialized Then pdfv.RemoveView
    pdfv.init
    
    Panel1.AddView(pdfv,5,1,Panel1.Width - 10,Panel1.Height -5)
    pdfv.getpdf(StrFile)
    If pdfv.isValid Then
        pdfv.scrollToPage(4)
        pdfv.zoom(1.0)
        
    Else
        Msgbox("Error pdf file!","Error")
        Activity.Finish
        Return
    End If
    
End Sub

Try to add a

Sleep(0)

before the ScrollToPage

I first set the zoom, then scroll.

In my case i am using

Sub Activity_Create(FirstTime As Boolean)
    'Do not forget to load the layout file created with the visual designer. For example:
    'Activity.LoadLayout("Layout1")
    Log("CopyFile()")
    If Not(File.Exists(File.DirRootExternal, "hm.pdf")) Then
        Log("test.pdf does not exist at DirRootExternal")
        
        File.Copy(File.DirAssets, "hm.pdf", File.DirRootExternal, "hm.pdf")
        Log("hm.pdf copied")
    End If
    pdf.init
  Activity.AddView(pdf,0,0,-1,-1)

    pdf.getpdf2(File.Combine(File.DirRootExternal,"hm.pdf"),"")

  If pdf.isValid Then
      Log("pagecount:"&pdf.GetPageCount)
    pdf.scrollToPage(0)
        pc=pdf.GetPageCount
        pdf.zoom(1.0)
        Sleep(0)
        pdf.scrollToPage(4)
   End If
    
End Sub

And it successfully scrolls to the last page
