>Got a CheckBox in a class library and want to use it instead of the default TextBox that's in one of the columns of my grid. How do I do that? Visually at design time. Thanks!

-Click your checkbox in toolbar, put it on form (anywhere will use temporarily).
-Set its properies (like Caption to none). Add code if any there while it's freely sitting on form (harder to do once got into grid).
-When you're ready. Select and cut with Ctrl+X
-Ctrl+Click your grid to set edit mode.
-Click the desired column
-Ctrl+V to paste. Copy its name.
-Select its column in PEM sheet
-Set CurrentControl to the name of checkbox you placed (Ctrl+V - you copied name above)
-Set sparse to .f.
-Set alingment to center
