How to list running programs in C#?

[Josh Argent]

I want to be able to set a string array to all the programs running (only the ones visible on the taskbar). Is this possible in C#? Thanks in Advance :D

Something like this may do it for you...

            Process[] processRunning = Process.GetProcesses();
            StringBuilder sbProcesses = new StringBuilder();
            foreach (Process currProcess in processRunning)
            {
                if (currProcess.MainWindowHandle.ToInt32() > 0)
                    sbProcesses.Append(currProcess.ProcessName + "\n");
            }
            MessageBox.Show(sbProcesses.ToString());

I get an error for 'processRunning' saying it does not exist in the current context :(. Thanks

Not sure if it alerts you on an edit, but I've added the line of code to make it work. Good luck.

Thanks bentleyw, works fine now :)

emm bentleyw, do you know how I can set a combobox to that array? I've tried comboBox1.DataSource = sbProcesses; but that doesn't work :( Do you know how I can do this? Thanks :D

[bentleyw]

Sure. Assuming that the ComboBox is named "cmbProcesses", you could use a list like this:

            Process[] processRunning = Process.GetProcesses();
            List<string> processList = new List<string>();
            foreach (Process currProcess in processRunning)
            {
                if (currProcess.MainWindowHandle.ToInt32() > 0)
                    processList.Add(currProcess.ProcessName);
            }
            cmbProcesses.DataSource = processList;

Or you could fill a DataTable (for example, if you want to carry other info along with each process) and set the DisplayMember property of the ComboBox to the column name from the table.

Thanks for all your help. I can now finish my application :D
