VB

Good afternoon to all.

I have developed a windows application in vb.net which is used edit pdfs. I have used web browser control to get and display a pdf file by means of ACROBAT 9 Pro. After I populate it, when I press CTRL+R the pdf will be opened in foxit pdf edit software. When I save there modifications will be updated in my browser.

Now my problem was with Acrobat 6 it was working fine. But in Acrobat 9, it will shows the error when I edit and try to save the pdf.

Error: Failed to save the document. Please check if the file is opened by another application

Refer the below code:

     Private Sub EditPDFToolStripMenuItem_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles EditPDFToolStripMenuItem.Click

    Dim objProcess As System.Diagnostics.Process
    Dim ProcessPath As String = "C:\Program Files\Foxit Software\PDF Editor\PDFEdit.exe "
    Try

        Dim procList() As Process = System.Diagnostics.Process.GetProcessesByName("AcroRd32")
        If procList.GetUpperBound(0) >= 0 Then
            For prc As Integer = 0 To procList.GetUpperBound(0)
                If procList(prc).ProcessName = "AcroRd32" Or procList(prc).ProcessName = "Acrobat.exe" Then 'Kill Arcobat Reader Application
                    procList(prc).Kill()
                    procList(prc).Close()
                End If
            Next prc
        End If
        objProcess = New System.Diagnostics.Process()
        objProcess.StartInfo.FileName = ProcessPath
        objProcess.StartInfo.Arguments = sFilePath & "\" & sFileName
        objProcess.StartInfo.WindowStyle = ProcessWindowStyle.Normal
        objProcess.Start()
        objProcess.WaitForExit()
        objProcess.Close()
        MyWebBrowser.Refresh()
    Catch err As System.Exception
        MessageBox.Show(err.Message)
        MessageBox.Show("Could not start process " & ProcessPath, "Error")
    End Try

End Sub
