Well it turns out the code actually does work. I'm not able to get it to work running it from my Server 2012 R2 lab server but from my 2008 R2 lab server it runs fine. I'll have to do some more investigating but at least I know the code is right!

Thanks!

How can I create a nested TreeView for Windows 8.1 app , data will be bind at runtime using C#? There is no Treeview Control in Windows 8.1 Development.

I'm not sure if this will meet your needs, but: [^].

And, when use the term "nested," what does that mean: isn't a TreeView an example of a structure designed to express "nesting" already ?

I don't work with XAML or RT, but I know one developer who uses the GroupedGridView to represent hierarchy: [^].

«OOP to me means only messaging, local retention and protection and hiding of state-process, and extreme late-binding of all things. » Alan Kay's clarification on what he meant by the term "Object" in "Object-Oriented Programming."

"It doesn't work" does not really help. As is, I'd be guessing that the order in which the columns are drawn are the opposite of what you want to achieve. That's simple; reverse the loop that does the drawing.

[SOLVED] Reading Process.StandardOutput from Echoprint Codegen.exe always returns empty string

Ray415287-Dec-14 13:32

Hello Everyone,

I have run into a coding problem that has been driving me crazy for two days. I am running a console project from within my C# project using Process.Start() and trying to read the output into a string in my project. I have tried everything that I have found on the internet over the last two days and nothing works. Always returning an empty string. I have tried both synchronous and asynchronous methods and everything in between ie reading standarderror as well as standoutput. The exe that is being called is codegen.exe which is the compiled binary for creating a song fingerprint in Echoprint.

I can run this from a code prompt and it works perfectly every time outputting a fingerprint string. I am running windows 7 / VS2013 Express. The funny thing is, I have the source code for the codegen.exe and the data being output to the console is using nothing other than printf statements so there is nothing surprising going on there.

I did try doing a simple call to cmd.exe with "dir" argument and it responds correctly and fills my string with its output.

I am hoping that someone can suggest something that I have not yet tried, however I have tried all the different examples from MSDN as well as the internet.

Perhaps some one has had a similar issue and can offer some suggestions or point me in a different direction.

Any help would be appreciated.

I have never used EchoPrint, or launched a Console Application using Process.Start from within a WinForms project, so what follows may be irrelevant, or useless, but, given the fact you've done thorough searching, and haven't come up with anything, and on the odd chance it may be helpful, I'll put it out here.

If I find out this is not relevant, I'll remove this message, and my "feelings" will not be "hurt" Smile | :)

Is it possible that if you launch a Console from a C# project using the 'AllocConsole API, you can then, somehow, get that Console running codegen.exe ... so you would, then, be able to interact ?

Your C# project is WinForms, or WPF, or C++ ?

The 'AllocConsole API works for me (only tested in .NET 4.5) to enable two-way interaction between a Win Form and a Console it launches:

[System.Runtime.InteropServices.DllImport("kernel32.dll")]
private static extern bool AllocConsole(); 

private void button1_Click(object sender, EventArgs e)
{
    AllocConsole();

    MessageBox.Show(ConsoleWriteAndReadLine(new string[]{"arg 1","arg 2","arg 3"}));
}

private string ConsoleWriteAndReadLine(string[] values)
{
    Console.WriteLine("Command line = {0}", Environment.CommandLine);

    for (int i = 0; i < values.Length; i++)
    {
        Console.WriteLine("argument{0} = {1}", i + 1, values[i]);
    }

    Console.Write("? ");

    return Console.ReadLine(); 
}

Perhaps the techniques shown in this CodeProject article would be helpful: [^] ?

Thanks Bill,

The project is a WinForms project and this is a code snippet from MSDN on how to do exactly what I want to do. But it never works.

// Start the child process.
 Process p = new Process();
 // Redirect the output stream of the child process.
 p.StartInfo.UseShellExecute = false;
 p.StartInfo.RedirectStandardOutput = true;
 p.StartInfo.FileName = "Write500Lines.exe";
 p.Start();
 // Do not wait for the child process to exit before
 // reading to the end of its redirected stream.
 // p.WaitForExit();
 // Read the output stream first and then wait.
 string output = p.StandardOutput.ReadToEnd();
 p.WaitForExit();

                process.StartInfo.Arguments = open.FileName + " 10 30";

                process.Start();

Wish I could be more helpful, Ray, but you're traveling in terra incognita for me. I was surprised I could get two-way interaction working starting-up the Console with 'AllocConsole.

Hopefully, one our deeply knowledgeable wizards will show up, soon, with the right incantations.

May be something like this will help:

Process P = new Process();
p.StartInfo.UseShellExecute = false;
p.StartInfo.CreateNoWindow = true;
p.StartInfo.RedirectStandardError = true;
p.StartInfo.RedirectStandardOutput = true;
p.StartInfo.FileName = "Codegen.exe";
p.StartInfo.Arguments = open.FileName + " 10 30";
 
p.Start();

p.OutputDataReceived += (o, e) =>
{
  if (e.Data != null)
   returnValue.AppendLine(e.Data);
};

p.ErrorDataReceived += (o, e) =>
{
  if (e.Data != null)
   returnValue.AppendLine(e.Data);
};

p.Start();
p.BeginOutputReadLine();
p.BeginErrorReadLine();

p.WaitForExit();
p.Close();
p.Dispose();

if (returnValue.Length > 0)
{
  standardOutput  = returnValue.ToString();
}

Harsh, thanks so much as this now works. I cant explain the difference between

p.OutputDataReceived += (o, e) =>
{
  if (e.Data != null)
   returnValue.AppendLine(e.Data);
};

and what I tried before which was using a separate handler assigned to OutputDataReceived.

Is your code different from

sortProcess.OutputDataReceived += new DataReceivedEventHandler(SortOutputHandler);

private static void SortOutputHandler(object sendingProcess, 
            DataReceivedEventArgs outLine)
        {
            //do something with outline.Data
            
        }

However your code works so thanks very much

I am glad that it worked for you.
Basically your code and mine is almost same. While your code is creating explicitly named event handler, mine creates anonymous function.

I think the difference is that I am capturing the stdErr output to the string variable as well.
