    Default Suggestion & one problem detected with RDS

    Hi! VRW Alpha II

    Suggestion: I want to be able to copy a text object from one report to the other.

    Question: is it possible to relate an RDS table with a sql table? (I get an "Only one database per table allowed")

    Problem: with RDS, I just created just ONE (1) record and look at the generated report in the attached image.

    Thanks in Advanced.

    Hi Boris

    For your question, use a subreport for the RDS table (fill the RDS by previewing the subreport once)
    see attachment how to pass a ID from SQl to the subreport/RDS.

    I can't reproduce the problem that you have, can you attach the report ?

    with Kind Regards

    Hi Boris,

    I'm guessing you have an empty row in the RDS sample data grid which will result in an empty record.

    I just opened VRW and double checked and I don't have an empty record.

    I just found out that I had 6 empty records (which I don't know how they got there) but it was impossible for me to detect it because the Runtime Datasource Data dialog only showed me the first record and there was not way to see this empty records.

    I found out in a bizarre way, because I added a "Page N of M" field in the header and it showed Page 1 of 7.

    There should be a better way to show us this empty records.

    Thanks for pointing me in the right direction.

    I have the following in my RDS reports which will dump the contets after I load it, before it's reported... WARNING, it's not pretty or elegant code....

            Procedure LoadRDSData String sReportId Integer iLevel
                Variant[][] vData
                Integer iElements iElement iSubReports iSubReport
                Integer i j iDim1Size iDim2Size
                Integer iCount iChOut
                tVRWTableName[] ReportTableNames
                String sSubReportId sFilename
                Get RDSTableNames sReportId to ReportTableNames
                Move (SizeOfArray (ReportTableNames)) to iElements
                If (iElements > 0) Begin
                    Decrement iElements
                    For iElement from 0 to iElements
                        Get AddRDSData ReportTableNames[iElement].sTableName iLevel to vData
                        // Right here is where we want to dump the data
                        // retrieve size of outer (leftmost) dimension
                        Move (SizeOfArray(vData)) to iDim1Size
                        // retrieve size of inner (2nd) dimension
                        If (iDim1Size > 0) Begin
                            Move (SizeOfArray(vData[0])) to iDim2Size
                        //Send Info_Box ("Array is" * (String(iDim1Size)) * "by" * (String(iDim2Size))) "Size"
                        // dump the array's contents
                        Move "C:\Arraydump2.txt" to sFilename

                            // Create a text file. Replaces the file if it already exists.

                                    Write channel iChOut vData[i][j]
