Checkbox and StartIndex Error

[ashehu@gmail.com]

When trying to uncheck a checkbox with the following simple line of
code
CheckBox8.Check ed = False
I get the following error
StartIndex Cannot Be less tha Zero
Parameter name: StartIndex
Its a windows application. When the form loads, some of the checkboxes
get checked based on a user selected. When another user is selected
some checkboxes get checked the checked states get checked.
Any help really appreciated.

Then your "simple line of code" is causing lots of other, complicated
lines of code to be run and one of /those/ is failing.

Pop a few breakpoints in the code that runs when a Checkbox is
checked/unchecked.

Thanks. The Checkbox_CheckC hanged Event was causing the error by
trying to remove a character in a string at position "-1".
Thanks Again
