RedirectingStandardError is redirecting standard output also

[kebo]

Hey all,
I've create a console app that handles some pdf conversions for me. In this app I send some text to the console and if an error occurs, I send text to Console.Error...

'for console writes...
Console.WriteLine("Converting page " & pageNumber.ToString)
 
'for error writes...
 Console.Error.WriteLine("An error occur during the pdf page conversion.")

I am then running the console app from a windForm app with this code...

Private Function pdfToImg(pdfPath As String, destinationPath As String, pdfToImgAppPath As String) As String
 
        Dim returnErrString As String = ""
         Dim p As New Process
        With p.StartInfo
            .FileName = pdfToImgAppPath
            .Arguments = String.Format("{0} {1}", pdfPath, destinationPath)
            .RedirectStandardOutput = False
            .RedirectStandardError = True
            .UseShellExecute = False
        End With
        p.Start()
        p.WaitForExit(30000)
 
        If Not p.HasExited Then
            p.Kill()
            returnErrString = "An unknow error has occured in the pdf conversion. The process never ended."
        Else
            returnErrString = p.StandardError.ReadToEnd
        End If
        Return returnErrString
 
    End Function

My intent is have the standard output go to the console, but redirect the error so I can display and log it, However when I set RedirectStandardError=True, it is redirecting all output including the standard output which I want to remain in the console window.

Has anyone seen this behavior before and know how to resolve it?
thanks

I know that with binding it makes a difference in the order of the lines (setting DisplayMember and ValueMember before setting the datasource)... have you tried switching the Output and Error redirects? So that you set the error redirect first, then the standard redirect? Can't say I've ever seen this before but then usually when I'm redirecting, I want it all ... never tried splitting it.

Curious to see if that makes a difference or not, and whether you get it working.

have you tried switching the Output and Error redirects?

Doesn't seem to make a difference. Setting the error redirect stops the console from updating.

FWIW WaitForExit should be called after ReadToEnd, according to MSDN
