    Unsure of the proper way to use Form.Location...

    I am trying to pull coordinates for a form location out of a database and insert them into the Location property:

    Code:
    childForm.Location = new Point(/* coordinates go here */);
    I have tried doing a direct replacement with the DataSet (which didn't work):

    Code:
    childForm.Location = new Point((string)row["location"]);
    And I have tried using a string to hold the coordinates:

    Code:
    string Loc = (string)row["location"];
    childForm.Location = new Point(Loc);
    ...which also didn't work. If I print 'Loc' to the screen, I can see it passing valid coordinates (in this case "100, 200" and "300, 600"), but it errors out when I try to pass that information to childForm.Location.

    Obviously I'm doing something very wrong here, but I was unable to find any examples of using non-static or non-relative coordinates. If you know, could you please tell me what my misatke is?

    Thanks!
    -Charlie

    What you are doing makes no sense. Look at Point's constructor overloads using intellisense.

    Do you see one that looks like this: Point.Point(string str) ?

    If you don't see a constructor overload with a string type parameter, then why would it make sense to try to initialize a point with a string?

    Knowing what a Point is and what it's used for, would this make any sense at all?

    Code:
    Point myPoint = new Point("Hello, World!");

    Chris, valid point but it didn't help me a single bit.

    I don't care if you're condescending, but the least you could do after mocking me is show me a correction.

    My apologizes if I came off condescending. Some people might not even understand the problem.

    That being said, I can't help you with the solution as I'm unfamiliar with DataSet. I don't work with SQL at all.

    What type is row["location"]? Is it a string? If so, exactly how are they formatted?

    It can be an int or a string. I have it as a string at the moment. (it carries coordinate values, raw numbers with a comma dividing them - that is it. ie: 20, 100).

    In that case it shouldn't be difficult.

    Code:
    childForm.Location = StringToPoint((string)row["location"]);
    
    private Point StringToPoint(string str)
    {
        string[] s = str.Split(',');
        int x = Int32.Parse(s[0]);
        int y = Int32.Parse(s[1]);
        return new Point(x, y);
    }

    And now I can see why I was being foolish...

    Thank you very much, Chris!
