TESTING FOR ARRAY "EMPTYNESS" OR "NULLNESS"?
Hi -
I have a string array dimensioned as Myarr(20). After operating on this array, some of its elements and eventually, each of its elements will be set to empty string "". How do I check that every single element of the array is ""? I tried Isempty() and IsNull() but it doesn't seem to work. Is there a vba boolean function that can check this? Thanks Jay *** Sent via Developersdex http://www.developersdex.com *** |

There is no function for that. You need to traverse the array checking each
element. -- HTH... Jim Thomlinson "jay dean" wrote: Hi - I have a string array dimensioned as Myarr(20).

Since the array is a String array, there is a simple way to do the test the
OP wants without looping through the array... If Join(Myarr, "") = "" Then ' All elements are empty Else ' At least one element has data in it End If -- Rick (MVP - Excel) "Jim Thomlinson" wrote in message ... There is no function for that.
