Command Prompt to richtextbox not display progress (%) line

Question

Command Prompt to richtextbox not display progress (%) line

Alisson 1

Hello.

I'm trying to view the prompt in a richtextbox but the last line containing the progress doesn't appear. I'm using a code posted by user @Castorix31 , it works perfectly except for that last line.

cmd

richtextbox (missing last line)

I can't post the code, here's an image.

Thanks for any help

@Alisson , Welcome to Microsoft Q&A, I can not test your code because it contains 3rd party product chdman exe. If you have trouble in reading the last line from the command line, you could try the following code in the question how-to-read-last-line-from-output-process-class

string lastLine = null; while (!process.StandardOutput.EndOfStream) { lastLine = process.StandardOutput.ReadLine(); }

Hello @Jack J Jun

Thanks for your information
I had to disable BeginOutputReadLine() to use ReadLine(), or it shows the error of "You cannot mix asynchronous and synchronous read operations..."
I used this code and nothing appears, it is completely null (no lines).
Tried all these with no result, nothing appears, no lines.

while (!p.StandardOutput.EndOfStream) { //StreamReader reader = p.StandardOutput; //string output = reader.ReadLine(); //lastline = reader.ReadLine(); //lastline += p.StandardOutput.ReadLine(); lastline = p.StandardOutput.ReadLine(); tConsole.Text += lastline; MessageBox.Show(lastline); }
