AccessViolationException when trying to change IsBalloon in a Tooltip popup event
I create a form, add a Tooltip, and in the popup event-handler I call
toolTip1.IsBalloon = true;
toolTip1.GetToolTip(Form1.ActiveForm);
Compiling and then running the test program then results in an AccessViolationException after the program leaves the popup event-handler.
What I had planned to do is to use a single tooltip control that sets the IsBalloon property depending on what control called the popup event, instead of using one tooltip control that is not a balloon, and one that is a balloon.
I guess the same can be achieved by looking at what control the mouse pointer hovers over, but then I wonder how to change the property in a safe way as I suspect it's a threading issue.
Forgot to write that this is tested in Visual Studio 2005 Standard with SP1 Beta1.
