Hi ertugrulkaya,

That is a Visual Studio warning regarding a standard programming issue. It has nothing to do with the PC SDK.

What that is saying is that you are using a null type declaration [ToolData aTool;] but you have an IF{} surrounding the allocation/assign [aTool = (ToolData)rd.Value;] so when it reaches the row in question it doesn't know if the IF{} really happened or not. If the IF{} didn't happen you'd get an unhandled exception.

The error would go away if you had the reading inside the IF{} or if you had an IF/ELSE scenario with an Exit if it wasn't a tooldata.
