I have created a program and made a label that says 'Status :' next to it says 'Program not running' I want to make it so that when i make the program opens CMD it changes the label text to 'Program running'. I know how to change the text but how do i make it so that the program detects when CMD is open or not?

Help is appreciated.

scan for process cmd.exe
If it's true then status.text ="Program Running"

Wow all these years I've been doing things unnecessarily complicated.

I don't understand the bottom way, and i'm using visual basic 2008 express edition so i don't think the 'FindWindow' command exists. I was thinking of something like 'If process "cmd" = running Then label1.text = Program running' I know that command doesn't exist but i need something like that. Confused

pinvoke, then call it.

or do it the managed way, which is probably smarter since you're using .NET

Look at the System.Diagnostics.Process class.

The GetProcessesByName method will be of use.

But i want to type it into the form code, so its like 'If Process("CMD") = running then Label1.Text = "Program Running" - Something similar.

How about you actually try reading the article?

It returns a process array, can you guess what happens when there's no match?
The array is empty.

Just use the API FindWindow, not sure if you can in VB, but yeah. Then just see if the HWND finwwindow == 1. Not sure to the VB equivilant.

Simple way to do it in VB.NET:

Code:
Public Function IsApplicationRunning(ByVal ApplicationName As String) As Boolean
    Return System.Diagnostics.Process.GetProcessesByName(ApplicationName).Length > 0
End Function


Note that you call this method with the friendly name of the executable - so you would do IsApplicationRunning("cmd") not IsApplicationRunning("cmd.exe"). The >0 part at the end of the Return line basically checks if any processes were found that match the name you specified and if so, return true (else return false).

If you want it in C# for whatever reason:
Code:
public bool IsApplicationRunning(string ApplicationName)
{
    return System.Diagnostics.Process.GetProcessesByName(ApplicationName).Length > 0;
}
