New Ubound Set, Will Everything After Ubound Be Removed?
Jan 19, 2011Here is a bit of code I found. It was said to remove a specific value in the array. However, it looks to me like it's setting a new ubound(end to array?), wont everything behind the new ubound be removed too?
Code:MyArray(ItemToBeDeleted) =MyArray(Ubound(MyArray))
RedimPreserve MyArray(Ubound(MyArray)-1)
Edit:Or is it just moving the value to the end and then just -1 from the end to remove it?

Use Of Mid(), Instr(), LBound(), UBound() Not Recommended?
Sep 28, 2009I come from a C# background but am now working mostly with VB.Net. It seems to me that the above functions (and others - eg. UCase, LCase) etc. are carryovers from VB6 and before. Is the use of these functions frowned upon in VB.Net, or does it purely come down to personal preference?
