Hi
i am trying to open a pdf file using vb.net with the following code. it gives an error messages at ar.src=splitout(i) and the message is "Attempted to read or write protected memory. This is often an indication that other memory is corrupt.". please help.
Thanks
Dim dlg As OpenFileDialog = New OpenFileDialog()
dlg.ShowDialog()

If dlg.ShowDialog = Windows.Forms.DialogResult.OK Then
Dim filestream As StreamReader = New StreamReader(dlg.OpenFile, System.Text.Encoding.Default)

Dim readcontents As String
readcontents = filestream.ReadToEnd()

Dim textdelimiter As String

textdelimiter = (" ")
Dim splitout() As String = Split(readcontents, textdelimiter)
Dim i As Integer
For i = 0 To UBound(splitout)
AR.src = splitout(i)
AR.Refresh()

System.Threading.Thread.Sleep(500)
Next

filestream.Close()
End If

It is a bad idea trying to read pdf files because the text could have been generated in any way.

Hi
Do u mean that the pdf file needs to converted to a text file before reading?

Thanks

Possibly yes

Imports System.IO

Public Class SaveClass
    Public Function GetContents(ByVal FullPath As String)
        Dim contents As String
        Dim read As StreamReader
        Try
            read = New StreamReader(FullPath)
            contents = read.ReadToEnd
            read.Close()
            Return contents
        Catch ex As Exception
            MsgBox(ex.Message)
        End Try

    End Function

    Public Function SaveTextToFile(ByVal strData As String, _
     ByVal FullPath As String) As Boolean

        Dim objReader As StreamWriter
        Try
            objReader = New StreamWriter(FullPath, True)
            objReader.WriteLine(strData)
            objReader.Close()
            Return True
        Catch Ex As Exception
            Return False
        End Try
    End Function
