Marking a grid cell?

I have created an application which uses a grid to display information.  The user may click on the grid to enter data to that cell.  I would like to know how to mark the cell once data has been entered so that overwriting is only permitted after some checks have been done?????  I wantedto set a variable to 1 for instance and us an IF statement to run the checks or set a variable to True.  But assigning it to just that cell has proved very difficult, can anyone help???????/

Hi, I think you must use Matrix techniques.

For examples, you define the grid 5x4 (5 columns, 4 rows).
You define to the arrays (if you want to dynamic rows cols, refer to how to use dynamic array (REDIM Statement)

DIM GridFlag(5,4) as Boolean

When user change the contents, mark true on your array. And so on.

Hope this help.. eventhough wasting memory. Well... I think there is no simpler way.
