Christophe: Just for the heck of it, put breakpoint on your sql string or put it into a message box and display it before you execute it. Check the format of that string to make sure that it is what you think it should be once it is constructed in the application.

I'm not sure that I follow you but if you are trying to write a VB.NET update statement using dynamic SQL, it should look something like this: (single quote, quote, ampersand, variable, ampersand, quote, single quote) "UPDATE Sensors SET SensorStatus = '" & strTemp & "' WHERE SensorID = '" & strSensor & "'"
