Could not convert variant of type (Null) into type (OleStr)

Question

Do you know why the block of code bellow will negate the \"Could not convert variant of type (Null) into type (OleStr)\" on some computers, not all of them but 3 out of ten comp

Answer 1

Sometimes, the FWbemObject is not NULL but an exception is raise : "Can'nt convert an Array of Variant in OleStr "

As exemple : the BiosVersion (is an array) To solve it, try this :

for I := VarArrayLowBound(FWbemObject.BIOSVersion, 1) to VarArrayHighBound(FWbemObject.BIOSVersion, 1) do L.Add( VarToStr(FWbemObject.BIOSVersion[i]) );
