    Problem with decimals

    Hi!

    I have a report that show prices, like $1.33
    The problem is that it is not showing decimals correctly, it shows 1.33 like $1.00

    I checked the field format, round rules, etc. Is not that.
    I checked regional settings. Is not that either.
    I checked dll (crystal) versions.

    In db (access) the value is right. Itīs a float type.

    My locale is Brazil, so, decimal separator is "," and tousand separator is "."
    (In the example above, i used dot as decimal separator just to explain).

    Iīm calling the report with vb6 (sp6). In Crystal Report (designer, 8.0.1.0) the price is correctly.
    It just happens when the report is called from vb program, and not in all computers. Just a few.

    Same EXE, same RPT and same DLL, but the problem occurs.

    Code in vb6:
    sql = "SELECT ... PRE_PEDIDO_ITEM.PPIT_VLR_UNIT, PRE_PEDIDO_ITEM.PPIT_VLR_LIQ, ... " & _
    "FROM ... PRE_PEDIDO_ITEM, ... " & _
    "WHERE ... "
    Rpt.LogOnServer "p2sodbc.dll", "DRP2", "DRP2", "XXXXX", "XXXXX"
    Rpt.WindowShowRefreshBtn = True
    Rpt.WindowShowSearchBtn = 1
    Rpt.WindowShowCloseBtn = 1
    Rpt.WindowTitle = "Order"
    Rpt.WindowState = crptMaximized
    Rpt.SQLQuery = sql
    Rpt.Action = 1

    Any idea?

    Re: Problem with decimals

    Can't you use a Currency data type?

    Re: Problem with decimals

    Itīs a legacy application that have been working for years.

    This is a recent problem, so I donīt think that change the database column type
    is the best solution. Itīs a ruge impact.

    tks.

    Well, what can we do, if it's NOT the code?

    Re: Problem with decimals

    Well, I thought that people in this forum could have face a problem like this.

    I think it could be something like windows hotfix conflicting with this old crystal/vb...
    and I was hoping that maybe you be experienced enough to help me, because right now,
    iīm desperate.

    I believe that this problem is less programming skill and more about experience/know how.

    Re: Problem with decimals

    Just because it used to work, doesn't mean that a change in coding can't fix it. In addition to the Currency data type, there is also the Format() function, which can return a number in the format of your choosing.

    [SOLVED] Re: Problem with decimals

    I fixed it.

    Before I call the report I change the regional settings by code using kernel32 api.
    And change it back after the report is loaded.

    Private Declare Function SetLocaleInfo Lib "kernel32" Alias "SetLocaleInfoA" (ByVal Locale As Long, ByVal LCType As Long, ByVal lpLCData As String) As Boolean

    Dim wInfo As Long
    Dim Locale As Long
    Locale = GetUserDefaultLCID()
    wInfo = SetLocaleInfo(Locale, &H16, ".")

    It still doesnīt explain why it was working in some computer and others not (they have the same regional settings configuration and same version off all software).

    But... itīs working now.

    Sometimes i think that computers is not a exact science as it should be

    tks.

    Well done.
    But it IS an exact science. It is possibly the most exact science there is at all, being always reduced down to 0 and 1.
    However, it is possibly also a very complex and sometimes intransparent science. But always exact.

    There is a saying; The nice thing about computers is that they do exactly what you tell them to do. The bad thing about computers is that they do exactly what you tell them to do.
