How to start/call an Asp.net core app when i open CefSharp(winform) browser and close it on exit?

Question

Tools used: Visual Studio 2019, Asp.net core 5.0, CefSharp.WinForms v79.0

I have created an asp.net core app and a CefSharp browser.

If i click on the app.core and then on the browser it works fine.

I would like to some kind "automate" the whole process.

How to start the Asp.net core app before the CefSharp fully loads/starts.

Can this be done from within the CefSharp browser,

so it opens the app.core in automatic and closes it too when CefSharp is closed?

i can already do this by cmd-line:

tasklist /fi "imagename eq APP.exe" |find ":" > nul

if errorlevel 1 taskkill /F /IM "APP.exe"

start C:\Server\APP.exe 

start C:\CEFSHARP\GUI.exe

Answer 1

You can start and stop process "C:\Server\APP.exe" from within GUI.EXE - this is assuming that you have a source code for GUI.EXE

You need to do the following in GUI.EXE source code (here I'm assuming that you are using Windows Forms application):

1. Add a Load event handler to your main form. From within your event handler you will need to start "C:\Server\APP.exe" . You can use System.Diagnostics.Process.Start(@"C:\Server\APP.exe"); within event handler to start a process. Note that this method will return Process object which can be used to close the application.
2. Add a Closing event handler to your main form. From within your event handler you will need to stop "C:\Server\APP.exe" You can do this via CloseMainWindow method of the Process object.

This worked for me:

Form1.cs

        private void Form1_Load(object sender, EventArgs e)
    {
        Process[] processName = Process.GetProcessesByName("APP");
        if (processName.Length == 0)
        {
            Process myprocess = new Process();
            myprocess.StartInfo.FileName = "C:\\Server\\APP.exe";
            myprocess.Start();
        }
    }



        private void Form1_FormClosed(object sender, FormClosedEventArgs e)
    {
        foreach (Process p in Process.GetProcessesByName("APP"))
        {
            p.Kill();
        }
    }
