Question

Can I make a DATAREPORT without datasource property being set

Asked by: adharwar

I need to print data not belonging to database. So I need to set the datafield of report textbox to a string value in a loop. How is this to be done?

The problem is untill I set the Datasource property of the DataReport the DataField and DataMember are not activated. Is there a solution for this or should I use something like crystal reports?

This can't be done using the datareport. This requires the dataenvironment and a database.
I every way Crystal reports is always the better choice.

Crystal Reports is, IMO, significantly better than the VB DataReport.  However, you are still going to have to get the information to C.R. somehow.

Is this just a title, or will this be information on each row of the report?  If it is something that could be calculated in SQL, you can modify your datasource to do the creation of the text field.

You could also look at creating a UserControl that can work as a datasource, or a class that could do what you need.  Both can be used as datasources for the Datareport.

This can be done.  Dataenvironment is possibly the best choice for a datareport, but you can design a datareport without a DE.  You do not have to bind the datareport to a database either:

datareport1.sections("Section1").Controls.Item("Text1").DataField= "mytext"

Yfang, I tried that but you get an error
saying 'Invalid DataSource'

 

by: mkmccrearyPosted on 2000-06-06 at 15:10:28ID: 2901704

Here is something that may help.  You create your own ADO Recordset.  You then populate that recordset.  Next you bind your report to that recordset.  Then you bind the field(s) in the detail section of your data report to the field(s) in your recordset.  Here is some sample code.  If you would like the whole project I can e-mail it to you.

Dim oRS As ADODB.Recordset

    Set oRS = New ADODB.Recordset
    With oRS
        .Fields.Append "Field1", adVarChar, 50, adFldUpdatable
        .Open
        .AddNew "Field1", "Value1"
        .AddNew "Field1", "Value2"
        .AddNew "Field1", "Value3"
        .AddNew "Field1", "Value4"
        .AddNew "Field1", "Value5"
        .AddNew "Field1", "Value6"
        .Update
        .MoveFirst
'        While Not .EOF
'            MsgBox .Fields("Field1")
'            .MoveNext
'        Wend
    End With
    With UnboundReport
        Set .DataSource = oRS
        .Sections("Section1").Controls("Text1").DataField = "Field1"
        .PrintReport False, rptRangeAllPages
    End With
    Set oRS = Nothing


Good Luck,

  I ran into the same problem with the ReportWriter that came packaged w/ VB6.
As far as simultaneously passing values from a form AND using a table to generate a report using solely the ReportWriter, I have yet to find a way to do that... effectively, that is.

   The way I've found to create this kind of report takes a little bit of legwork and it doesn't take advantage of the report's banded capabilities.  But since the data you want to report doesn't come from a database, this should work just perfectly for you!

1) Create your report just the way you want it to look on paper.  IMPORTANT NOTE:  Instead of using textboxes to display the data on the report, use LABELS!!  This is necessary because you CANNOT directly assign textbox values -- they are bound controls.  You can, however, manipulate labels.

2) Create a DataEnvironment.  Point your report to a "dummy command".  This command can be any "SELECT" statement.  I would suggest using "SELECT TOP 1 *" from any table.  I call this a dummy command because:
     a)  The data report REQUIRES you to bind it to a command.
     b)  You will NOT be using this command.  It simply serves to fulfill the requirment I've described in 2a.

3) In your form, get your recordset that you will be using in your report.

4) Assign these values to the labels in the report.  Here is how:

DataReport.Sections ([Index#]).Controls("[Label Name]").Caption = (Value)


Here is how to determine the "Sections"'s index number:

SECTIONS - The indexes are numbered by section, from top to bottom in sequence.  The top-most section is '1', the next one beneath it is '2', and so forth.

CONTROLS - Place the Label's name in this section surrounded by quotes

This should take care of it!
Good luck!
