Have you checked the actual value that causes the error?

Have you checked https://forums.techguy.org/threads/solved-access-error-overflow.669553/ the actual value that causes the error?Click to expand... I couldn't tell if it was just one value or not. If I copy the sql to design view I just get the overflow error immediately. I then removed the calcs and the query would run. Then I started playing around to see if I could get the calculations to work. I changed all values in the original table to doubles and set the "group by" total to expression. I have it working for now, so I hope that will suffice. Thanks! Roger rconverse, Jan 8, 2008 #4 This thread has been Locked and is not open to further replies.

"Overflow" https://bytes.com/topic/access/answers/472271-overflow-error error P: n/a SheldonMopes I sometimes get a pop-up box that reads "Overflow" and the module that is executing pauses. It doesn't get caught by my error trapping, and it http://stackoverflow.com/questions/26659256/how-to-turn-off-overflow-check-in-vba-for-ms-access seems to be randow. By random, I mean usually in the same section of code, but I can run the code a few times, then it appears. I can't reproduce overflow error it when I want to, and I have no idea what is causing it. Any ideas ? Thanks By the way the code is some record manipulation of 2 recordsets. Mar 24 '06 #1 Post Reply Share this Question 3 Replies P: n/a Allen Browne Overflow means that the data is too large for the data type that is trying to overflow access error handle it. Open the Immediate Window (Ctrl+G), and enter: ? 200 * 200 The default number type in Access is Integer, and the largest integer is 32767. Therefore this simple calculation fails with an Overflow error. The solution is to force one of the numbers to be a Long integer, e.g.: ? CLng(200) * 200 Your calculations may therefore need typecasting to a Long, Double, or Currency, using CLng(), CDbl(), or CCur(). Note that these types do not handle Null, so you usually need to use Nz() inside those expressions too, e.g.: CCur(Nz([Quantity],0)) * [PriceEach] More info: Calculated fields misinterpreted at: http://allenbrowne.com/ser-45.html -- Allen Browne - Microsoft MVP.

Since I cannot fix it and there are no sample code solutions on how to fix the overflow error with left shifting, I`d like to try and turn it off to see the result I get. I cannot find it in options. vba ms-access share|improve this question edited Jul 27 '15 at 3:07 JasonMArcher 6,26183744 asked Oct 30 '14 at 17:12 AndroidNFC 458322 2 Change As Integer to As Long. –David Zemens Oct 30 '14 at 18:08 add a comment| 3 Answers 3 active oldest votes up vote 4 down vote I cannot find it in options. This is because it is a runtime error, not an "option." Most likely a cause of an Overflow error is trying to slick a number that's too huge for the data type. Byte type is for 0-255. Integer type can hold numbers up to 32,767. Long data type can hold numbers up to 2,147,483,647 so it's probably better suitable for your specific case. Adjust your variables types accordingly. Generally, VBA converts all Integers to Long these days so it's a better practice to dim your variables as Long by default. Here is an excellent writup as to why you should use them as Long. share|improve this answer edited Oct 31 '14 at 13:05 answered Oct 30 '14 at 17:14 enderland 5,94993187 Thanks for the significant edit, @Vba4all. –enderland Oct 31 '14 at 12:51 don't worry :-) –user2140173 Oct 31 '14 at 12:53 add a comment| up vote 3 down vote Here is how you left shift a Byte without overflowing: Dim abyte as Byte abyte = &H81 '10000001 'To shift left, you multiply by 2, BUT because the msb is 1, multiplying by 2 gives you an Overflow.
