When "copying" in data using ExportArray and there are empty cells in the sheet Excel usually sets the cell-value to: [Null] - which can be checked with standard embedded software tests for empty. However AsPose returns (NULL). It seems as if (NULL) is an .NET Exception - but I do not understand how AsPose or why (NULL) is being returned. Then again the data are being exported so why it should be an .NET exception I do not understand.
My qeustion is: In an editor I can see this (NULL) but how do I check for it under program control - somethings like a method that returns a 1 if it is (NULL) and 0 elsewise - or similar stuff?
