[AccessD] Loop Until Date=Date

Hi Mark

When they match and you stop the loop, do a

  Debug.Print CDbl(RecordDT), CDbl(RecordDT_end),  CDbl(RecordDT - RecordDT_end)

and I guess you'll see why.

Hello All,

Thanks for the suggestions.  I found last night that "DateDiff("s", RecordDT, RecordDT_end) = 0" would work...but I just can't seem to understand why they were not equal.  I tried the suggestion below...but it failed as well.  I also tried "If RecordDT>= RecordDT_end"...this works...but scares me because I don't know why it works and "=" does not.  I think I will just use the datediff approach...but am still curious...


Thanks,

Mark A. Matte
