  • Yes. TraTppReportRTTI is defined in ppReport.pas. You could descend from
    this class and add more properties. Then in the initialization section of
    your unit unregister the existing class and register your custom RTTI class.

  • You will need to extend RAP with one or more custom functions to do what you
    need.
    (Not all properties and functions are exposed to RAP.)

    Article: Extending RAP

  • Use the Report.OnGetAutoSearchValues event to access the AutoSearchField
    values entered by the user.

    The Report.AutoSearchFields[] array provides access to the autosearch fields
    associated with a report. The AutoSearchFi…

  • The ReportBuilder AutoSearch feature is designed to handle parameterized
    queries that display an ask-at-runtime

    1. Use the Query tools provided by the Data workspace to create query
    dataviews. Use the Search tab of the Q…

  • 1. As a simple base line test configure a set of simple one page reports to
    print with each of the required settings and test to determine whether that
    works. (Perhaps you have already done this).

    2. Once you get number …

  • RAP has limited supported for typecast. When you use it in an expression
    like that, it does not work correctly.

    The solution is to use a local variable to store the typecast reference.


    var
    lSubReport: T…

  • My mistake, I was not thinking about RAP not having access to the Sender.

    I created a patch for RB 9.02 that adds a NodeCreator parameter to the
    OnOutlineNodeCreate event for RAP. I will email it to you.

  • I think the Sender parameter of the OnOutLineNodeCreate event is the Report,
    SubReport, or Group that is creating the node.

  • RAP does not currently support DataPipeline events.

    Can you provide more details about what are you trying to accomplish?
    Perhaps there is an alternative approach.

  • Access the childreport.MainReport property and typecast it as TppReport.


    Example:

    var
    lMainReport: TppReport;

    begin

    lMainReport := TppReport(Report.MainReport);

    lMainRepor…

  • To customize the autosearch dialog, please see
    RBuilder\Demos\AutoSearch\Custom AutoSearch Dialog. The technique does not
    involve RAP at all.

    a. Step 1

    Create a custom autosearch dialog and register it for use…


  • I do not understand this question. You can create a RAP RTTI class that
    describes any class.


    This example shows how to iterate over the RAP programs associated with
    Report's TraCodeModule.


  • Try the following

    lsFieldValue := myPipeline.FieldObjects['SomeBlobField'].AsString;

    The myPipeline.FieldObjects[] provides access to the TppField object. The
    TppField object has an AsString function.


  • The example passes the DataPipeline object to the TdaSQLBuilder constructor.

    lSQLBuilder := TdaSQLBuilder.Create(Customer

    All of the components in ReportBuilder have a UserName property that is used
    by RAP to resolv…

  • I had never tried using TdaSQLBuilder to modify the sql text, so I gave it a
    try and it appeared to work.

    I tried a Delphi example and then a RAP example - see both below. I used the
    RB 9.02 and the BeforeOpenDataPipelin…

  • I would try to get this working using Delphi code and then code a pass-thru
    function that can be called from RAP.

  • One option is to use the Report.OnInitializeParameters that was added for RB
    9.

    The Report.BeforeAutoSearchDialogCreate event can also be used. However,
    note that this event will only fire if the Report.AutoSearchFieldCo…

  • The ReportBuilder RichText is wrapper around the Delphi TRichEdit class. The
    properties of the RichText.Paragraph object can be used to set the alignment
    of the selected text (i.e. the RichText.SelText).

    You will need to…

  • Upate to RB 9.03.

    If you are a registered user of RB 9.x and did not receive notifaction about
    RB 9.03, please email info@digital-metaphors.com with your serial number and
    registration information and request it.

  • I researched this and have created a patch for RB 9.02.

    Another alternative is to access AutoSearch.SearchExpression property. It
    always returns the string entered by the user. (But I realize in this case
    you are looking…

  • I cannot reproduce either one of these in my testing here and we have had no
    reports of any compatibility issues between upgrading reports written in RB
    7.x.

    Perhaps you have a corrupt installation. Try following the ins…


  • Those are simple integer constants. If applicable you can use any of the
    constants defined in ppTypes.pas. Otherwise defin and use your own custom
    id's. Sorry if that was not clear.

  • 1. Event prop list

    If the event is not published, then override the GetEventList method and add
    it to the list. (if its published it will be added automatically).

    2. Event Id

    For each event, you need to h…

  • That syntax provides read-only access to the values. To set a value use the
    following:

    Report.Parameters.Items['paramName'].Value := CurrentDate;

  • If you would like to create a simple example that we can run here, email in
    zip format to support@digital-metaphors.com. Please use standard Delphi
    components and RB.



  • I do not recall there being any variable issues with RB 7.04.

    For calculations, make sure that you use TppVariables and the
    TppVariable.OnCalc event to perform the calculation. As an example, check
    out the RAP demos.

  • There is not a way to catch an exception in RAP. Therefore, I suggest
    creating a pass-thru function that returns a boolean indicating a successful
    load. Define a function that takes two parameters: the TppImage object and a
    f…

    Please do not cross post messages. TIA




  • You could do that also - connect the subreport to the same datapipeline.
    Each report/childreport will traverse the datapipeline to which it is
    assigned.

    I was originally thinking of creating a second SQL query that summa…


  • One way to do this is to use SQL to create a summary query that contains the
    grouped calculations. Then use a subreport in the summary band. The
    subreport can traverse the summary query and generate the results.
