Since Measure is designed for performing basic DAQ, GPIB, or Serial tasks, National Instruments does not support VBA scripting. There are two main resources from where you can receive assistance with VBA programming. The first is the National Instruments Developer Zone, where there are over a dozen Excel examples that you can use as a starting point for your VBA and Measure application. You can find a link to these examples at the Measure support site (http://www.ni.com/support/meassupp.htm). If you need further assistance, the Microsoft Developer's Network (http://msdn.microsoft.com) has some excellent resources for writing VBA scripts in Microsoft Excel.
