[Question] Adding to list in case "say"

2015-05-12 09:29:07

Can't seem to add items to a ListBox in case say.

if(playermessage.StartsWith("!admin") && AdminList.Items.Contains(username) && checkAddadmin)
{
    AdminList.Items.Add(playermessage.Substring(7));
    say(playermessage.Substring(7) + "is now an admin");
}

The above mentioned code does not work.

}

You're probably receiving the error that you're trying to access a GUI element outside it's main thread.
To solve this you'll have to access the main thread (or something, I found this code snippet on stackoverflow a while ago).

MethodInvoker mi = delegate
            {
                // GUI element changes put here, in your case:
                AdminList.Items.Add(playermessage.Substring(7));
            };
            if (InvokeRequired)
            {
                BeginInvoke(mi);
            }
            else
            {
                mi.Invoke();
            }

I'm putting everything in a try and catch, and I'm not catching any exceptions, so that might be it. I'll try. Thanks for the help.

playermessage == "!admin" has to be playermessage.Contains("!admin")
or playermessage.StartsWith("!admin")

I wrote this code separately, so in my original code its StartsWith()

▼"code"
MethodInvoker mi = delegate
{
// GUI element changes put here, in your case:
AdminList.Items.Add(playermessage.Substring(7));
};
if (InvokeRequired)
{
BeginInvoke(mi);
}
else
{
mi.Invoke();
}

How exactly do you use a MethodInvoker class?

I understand how it works, like a function in JS, but what is:

den3107 wrote:

if (InvokeRequired)
{
    BeginInvoke(mi);
}
else
{
    mi.Invoke();
}

What does it do? When does it execute? What is an InvokeRequired?

... you could just do at Form1() { }

CheckForIllegalCrossThreadCells = false;

Problem solved.
I used this in my bot and it worked.
