I have a form when it loads run a module to get sql server instances. These are in a array. I use this array to load a combo box on the form. User selects the instance and then presses a button. This button does some work and asks if we want to work on next instance.
Now i do not want to display already used instance name in combo box.
But as form will load again, it will run module again all instances in combo box again.
all help/idea is appreciated.

If you don't want to use LINQ, you will need to loop through the list of arrays and remove previously used servers.

Solution 1

So keep a list of the strings you have used, and remove them from the array before you load the combobox.

C#

    string[] servers = GetServers();
    servers = servers.Except(usedServers).ToArray();
    ...

private List<string> usedServers = new List<string>();

Solution 3

Or you can just check whether the selected Item is already inside the database using a simple select statement, then if it exists, then the item should no longer be in the combobox.
