Dear all,

I have a crystal report which has a lot of detaildections. In 3 sections there are 3 subreports. (1 subreport per section).

If there is no data available I would like to hide the section. This works perfectly for the no subreport sections.

It also works perfectly if there is no data in the whole subreport.

However in some cases the subreport also has section and if there is not data for that one particular section I would like to hide it. I can do this, but then it hides that section for all records in that subreport. I only want it for that specific section.

I hope that makes sense. If you need more info please ask.

My code is as follows:

Do While Not rs.EOF
            bFound = True
            With dsCVForClient
                .dtPersonalDetails.Rows.Add(rs.Fields(0).Value, rs.Fields(1).Value, rs.Fields(2).Value, rs.Fields(3).Value, rs.Fields(4).Value, rs.Fields(5).Value, rs.Fields(6).Value, rs.Fields(7).Value, rs.Fields(8).Value, rs.Fields(9).Value, rs.Fields(10).Value, rs.Fields(11).Value, rs.Fields(12).Value, rs.Fields(13).Value, rs.Fields(14).Value, rs.Fields(15).Value, rs.Fields(16).Value, rs.Fields(17).Value, rs.Fields(18).Value, rs.Fields(19).Value, rs.Fields(20).Value, rs.Fields(21).Value, rs.Fields(22).Value, rs.Fields(23).Value, rs.Fields(24).Value, sClient, sVacancy, sConsultant)
                rsInHouse = gCnn.Execute("select regno, tertiaryinstitute, course, duration, completed, subjects from tertiaryeducation where regno = '" & sRegNo & "'")
                Do While Not rsInHouse.EOF
                    For i = 0 To 5
                        If rsInHouse.Fields(i).Value = "" Then sTertiaryEducation(i) = "Not specified" Else sTertiaryEducation(i) = rsInHouse.Fields(i).Value
                    Next
                    .dtInHouseOtherCourses.Rows.Add(sTertiaryEducation(0), sTertiaryEducation(1), sTertiaryEducation(2), sTertiaryEducation(3), sTertiaryEducation(4), sTertiaryEducation(5))
                    rsInHouse.MoveNext()
                Loop
                rsJobHistory = gCnn.Execute("select regno, company, jobtitle, datestarted, dateleft, tasks, reasonleft, duties from jobhistory where regno = '" & sRegNo & "' order by datestarted DESC")
                Do While Not rsJobHistory.EOF

What logic are you using to hide/unhide the section ?

I just don't see it. Confused | :confused:

You have to remember that when you create a "Supression" formula in Crystal, you have to make sure that you have logic to both hide (supress=true) and unhide (supress=false).

Regards,
David

Hi David,

Thank you for your reply.

Ok the reason you dont see it is becuase maybe my brain is on overload and I posted the section it populates the dataset. The reason being is I thought maybe it could be done there somewhere. But on second thought it cant be done there.

A short sample:

If dsCVForClient.dtPersonalDetails(0).ComputerPackages = "" Then rpt.DetailSection49.SectionFormat.EnableSuppress = True

If dsCVForClient.dtInHouseOtherCourses.Count = 0 Then rpt.DetailSection50.SectionFormat.EnableSuppress = True

To get to the subreport, i used:

rpt.Subreports(0).ReportDefinition.Sections(5).SectionFormat.EnableSuppress = True

But it led to the seciont being suppressed for all the records in the subreport.

The personaldetails will only ever have 1 record for this report, but the subreports could have anything from 0 to 100 records.

David Mujica21-May-09 6:01

If appears that your logic sets the suppression to "TRUE", but never sets it to "FALSE".

I think the answer is to put an Else clause and set the suppression to FALSE.

give it a try. Cool | :cool:

jinxster21-May-09 6:25

Thank you, that was a great suggestion.

The bad news is though, it didnt work. What happens then is it enabled the section for all the records again. So if the last record did have a vaule in the field it unhid the section for all the records.

For i = 0 To dsCVForClient.dtInHouseOtherCourses.Count - 1
    If dsCVForClient.dtInHouseOtherCourses(i).Subjects = "" Then rpt.Subreports(0).ReportDefinition.Sections(5).SectionFormat.EnableSuppress = True Else rpt.Subreports(0).ReportDefinition.Sections(5).SectionFormat.EnableSuppress = False
Next

I seem to think the secret lies in the rpt.Subreports(0).ReportDefinition is there some way to talk to a record in that subreport? Confused | :confused:

David Mujica21-May-09 6:29

You can write a fomula to supress the "detail" section of the subreport, effectively suppressing the output for each record as you see fit.

jinxster21-May-09 6:45

How are you interacting with Crystal ?

21-May-09 6:45

Thats what I am looking for.

The question is how do i get to each record?

You havent got some code? (just the object with the periods...) Big Grin | :-D

David Mujica21-May-09 8:13

Re: How are you interacting with Crystal ?

21-May-09 8:13

Here is a basic idea of how I imagine you are using Crystal Reports.

1) Using Visual Studio (VS) you create a Crystal Report design (.rpt file)
2) Using VS you have your application display the report using the CrystalReportViewer.

My example code is actually from an ASP.Net application, but the idea is the same.

Dim rpt As New ReportDocument

rpt.Load("\myReport1")
 
'For example purposes, imagine that the myDataSet is populated already

rpt.SetDataSource(myDataSet)
 
CrystalReportViewer1.ReportSource = rpt

Based on this design, you would put the hide/unhide logic in the Crystal ".RPT" file. You don't have to do anything programatically with VB.

Is this how you are working with Crystal ? Unsure | :~

From your examples, I don't think so.

My impression is that the VB.net code should:
1) Create the dataset
2) Invoke the Crystal Report via the CrystalReportViewer and let Crystal do the formatting.

Are we on the same page? Confused | :confused:

Re: How are you interacting with Crystal ?

21-May-09 18:46

Hi David,

We are on the same page.

That is basically how mine works too...

Dim rpt As New rptCVForClient()

'Code to hide sections

Try
    rpt.SetDataSource(dsCVForClient)
    crvReport.ReportSource = rpt
Catch Excep As Exception
    MessageBox.Show(Excep.Message, "Error", MessageBoxButtons.OK, MessageBoxIcon.Error)
End Try

The problem is I have unbound text boxes in the sections that make the suppressing via property setting not work. I should probably change that, but I have never made a bound label in crystal reports... as er.. weird as that may sound.

David Mujica22-May-09 3:49

Re: How are you interacting with Crystal ?

22-May-09 3:49

Wow. I think you may have made your life harder by not using bound fields. I would start with working on getting all of your fields on the report to be bound to fields in the dataset. Or you can create formula fields that are based on fields in the dataset.

The report shouldn't be that complicated.

jinxster22-May-09 18:53

22-May-09 18:53

Hi David, thank you!

The report is working as it should. Thanks for your perserverance and help!

Thumbs Up | :thumbsup:

Great accomplishment

Yes.
Something has gone wrong.

Unfortunately without more information, it is almost impossible to guess what that is.

I have this situation

form1 is MdiPArent
Form2 is MdiChild which will be displayed in form1
Form3 is MdiChild which suppose to be displayed in form2

I tried to set form2 IsMdiContainer to True but it did not work.

How I can Display Form3 inside form2, and form2 inside form1?

TIA

Some clues.

A Form is derived from Control.
It is possible to parent controls in a Form.

Think about it!!!

by using win32 API yes I can.

But before I go for API solution, I try to see if this ability is available in vb native code.

Thanks in advance for any help.

You do not need Windows API.

................
// rest of your code
Dim form3 as New Form3;
form2.Controls.Add(form3)

As I said before a Form instance is really an instance of a Control, and can be treated just like a control, in most instances.

Hi
You should excuse me. The stupidity bill I take last long more than expected.

for 5 hours and before you post this, I was thinking that you are telling me that what I am asking for is not possible, since Dave also answer that it cannot be done in Mdi.

Just before 10 minute I got what you are asking me to do. You was guiding me to the solution, and I thought something else.

That is totally something new to me.

That did job perfectly.

Thank you very much.
