Random "OK" showing up in MTEXT

Anonymous — Tue, 29 May 2012 15:29:50 GMT

Hey everyone,

I've found some example code on how to create Leaderline and have been playing around with it. So far so good, but when I create my leaderline and the Mtext generates, it is always preceeded by an "OK" and i can't figure out where it's coming from. I've tried using TrimStart on a number of the strings to no avail. I know it must be something insanely simple but it can't seem to get it. Any input would be awesome!

            // Get the current value of DIMBLK
            string oldArrName = Application.GetSystemVariable("DIMBLK") as string;

            // Set DIMBLK to the new style
            // (this action may create a new block)
            Application.SetSystemVariable("DIMBLK", newArrName);

            // Reset the previous value of DIMBLK
            if (oldArrName.Length != 0)
                Application.SetSystemVariable("DIMBLK", oldArrName);

Just change this line within the code:

mt.Contents = pres.StringResult;
