about integrate mayo TO WPF

[DDman1984]

Hi,
I plan to integrate mayo.exe into my WPF application. I've been trying to capture the progress of file conversion through the process (just like the text you showed in the example this), but the results have been frustrating...
How can I achieve the above requirement?

please give me any advice thank you very much:)

Hello @DDman1984
mayo.exe "refreshes" the whole contents of the progress text each time there's some update(eg task ended or progress change)
So if you connect to the standard ouput channel of mayo.exe this is what you should get with this pseudo-code:

while (mayoProcess.hasOutput) {
    string msg = mayoProcess.readAll();
    print(msg);
}

For example running mayo.exe D:\dev\data\cax-if.org\as1-oc-214.stp --export D:\dev\data\cax-if.org\as1-oc-214.stp.stl would produce these successive messages:
0% Importing...

Hi, @HuguesDelorme

Thank you for your advice and response. In fact, I've tried using C# process APIs and consulted the .NET official documentation. However, I still haven't been able to obtain Mayo's output log during the conversion process.

I'm including my code below in the hope that it can help you understand my issue. Thank you very much.

public partial class MainWindow : Window {
    public MainWindow() {
        this.InitializeComponent();
        var proc = new Process
        {
            StartInfo = new ProcessStartInfo
            {
                FileName = "C:\\Program Files\\Fougue\\Mayo\\mayo.exe",
                Arguments = "C:\\Users\\User\\Downloads\\QG76_CFM_5p.stp --export C:\\Users\\User\\Downloads\\test.glb",
                UseShellExecute = false,
                RedirectStandardOutput = true,
                CreateNoWindow = true
            }
        };
        proc.Start();
        string q = "";
        while (!proc.HasExited)
        {
            q += proc.StandardOutput.ReadToEnd();
        }
        Console.WriteLine($"output : {q} ");
    }
}

The above code can launch Mayo and perfectly convert the model to the glb format, but I'm unable to retrieve any output text by the C# process from mayo...@@

update:
hi, @HuguesDelorme
#include <iostream> int main() { std::cout << "Hello World! DDMAN TEST"; std::cout.flush(); }

I made a simple attempt to write a C++ console application that can capture output messages through the C# code above. I reviewed the cli_export.cpp code you wrote, and in terms of output logic, it doesn't seem to be significantly different. However, I noticed that you are managing output messages through tasks. Please forgive me, as I'm not very familiar with C++. Could this be a potential issue?
