Reading Stream After RedirectStandardOutput=True Blocksoutput showing the progress of the diagnostic tests being run. If I create a Windows Forms app to run Netdiag using System.Diagnostics.Process I can only get the output in a single block. That is to say, if I redirect standard output to a stream, I can call ReadToEnd() on the stream and when the process has finished I get a splurge of text to output to the screen. If I use Peek() in a loop to see when there is a character to read, it always returns -1. It appears that although Netdiag is generating output, it is not getting written to the stream. Is there some way to read the output as it is generated, rather than all in one hit at the end? I have tried putting each of the bits in their own threads but it doesn't seem to make any difference. TIA Charles Problem solved. A great example can be found here (The Code Project) for
anyone who is interested. http://209.171.52.99/csharp/LaunchProcess.asp?print=true Charles Show quoteHide quote "Charles Law" <bl***@nowhere.com> wrote in message news:ehSdx3NSGHA.5156@TK2MSFTNGP10.phx.gbl... > If I open a DOS console window (CMD) and enter "Netdiag /v", I get > periodic output showing the progress of the diagnostic tests being run. > > If I create a Windows Forms app to run Netdiag using > System.Diagnostics.Process I can only get the output in a single block. > That is to say, if I redirect standard output to a stream, I can call > ReadToEnd() on the stream and when the process has finished I get a > splurge of text to output to the screen. > > If I use Peek() in a loop to see when there is a character to read, it > always returns -1.

Thanks for the link. I have just tried it, and it exhibits the same problem I am now getting. It doesn't show the full output. Try this netdiag /v and see what happens. The last thing you should see is "... command completed successfully". Instead it stops short of the end, sometimes mid-word. Any thoughts? Charles Show quoteHide quote "Herfried K.

Can you confirm that you get the same? Is there a fix?

I want to show you this. Being busy with it, I saw a problem you had in past that is done in this (Bitconverter). Beside that do in my opinion all webbrowsers solutions interest you . http://www.vb-tips.com/default.aspx?ID=58514c5a-5f5d-4b6d-a7bd-da738cdc7c2c Cor Show quoteHide quote "Charles Law" <bl***@nowhere.com> schreef in bericht news:ulx4F$dSGHA.424@TK2MSFTNGP12.phx.gbl... > Herfried > > Can you confirm that you get the same?

Yes, they do, although I am not currently working in that area, I still play around with it from time-to-time.
