[RESOLVED] Setting DB location during codeing in CR 11

[khandu]

Hi

While making a report in CR11 we specify the DB

But What if I wanna specify the DB during codeing..

How do i do that.. the DB is in location

app.path & "\DB\data.mdb"

thanks

[khandu]

please help..

because what is happening.. when i create an installer and run the prog.. then the viewer asks for path again because the specified path during design time is not the same as the installed path.. so this can be a lot of problem...

if you are working in VB then read crystal report tutorial at my signature.

[khandu]

I did check that..

could not find any code which was showing a path to DB.. all are connecting to rpt..

[shakti5385]

Out you DB and the report at the App.Path

[khandu]

so like


With CrystalReport1
.ReportFileName = App.Path & "\ReportName.rpt" & "\db\db.mdb"

[shakti5385]

so like


With CrystalReport1
.ReportFileName = App.Path & "\ReportName.rpt" & "\db\db.mdb"

No post your whole code

[khandu]

not working on code

[shakti5385]

are you using VB.NET

[khandu]

VB 6.0

i got the above code help from another person..

please help with the DB path

[shakti5385]

But What if I wanna specify the DB during codeing..

No need
use the DB Path in the connection USE the DSN for the report.
I make report In the VB 6.0 using the DSN not the DB Path

I suggest you that if you are using the connection string in the project then use the DSN
ans make report using the DSN
Then they call automaticallly

[khandu]

Hi

Some help here Shakti please.. show me what codes to add on top to define "app.path & "/db/db.mdb"

thanks

[shakti5385]

Tell me what are you using in your project DSN or connectionstring

[khandu]

as i showed u the code on top..

I designed a rpt in CR11 directly and gave a direct connection to it and picked up fields from there.. so its always asking for that path which i gave from browse.. i think its DSN..

the pic above shows i gave a direct connection

[khandu]

bump.. help plz

[khandu]

shakti

please help out

how to mention to pick db from app.path & "\asd\db.mdb"

please help here..

I have never used CR 11 but the CRAXDRT of prior versions all have a method that lets you specify the database location of every table. Something like

For Each DatabaseTable in DatabaseTables
DatabaseTable.SetLocation App.Path & "\Data\Database.mdb"
Next

I don't access to Crystal right now so cannot confirm the actual method names. Anyways, use the help file or object browser to find the object/method you need to call.

[khandu]

the method

.setlocation is not showing in the CR 11

[brucevde]

.SetLocation was just my guess for the method name.

What other methods are there in CR 11? You are allowed to think for yourself...

[khandu]

cannot find any such method for it.. :(

[brucevde]

According to the online documentation, use the SetTableLocation method, Location property or the ConnectionProperties property of the DatabaseTable object.

[khandu]

I tried this.. i use DAO for connection to DB in the project


For Each crxDatabaseTable In crxDatabaseTables
crxDatabaseTable.SetDataSource App.Path & "\database\db.mdb"
Next


Gave the error

Run time error 424 Object required

This is the syntax showing for setdatasource


SetDataSource Method (Database Object)
The SetDataSource method is used to provide information about a data source to the database driver associated with this Database object at runtime. For instance, if a report has been designed using the Crystal Active Data Driver this method can be used to provide an active data source for the report, such as a DAO, ADO, or RDO Recordset or a CDO Rowset. In this case, the object passed to the second parameter of this method replaces, at runtime, the field definition file used to create the report. This method can be invoked only in formatting Idle mode. When using a secure connection such as SQL Server, some additional code is required

Syntax
Sub SetDataSource (data, [dataTag], [tableNumber])

[brucevde]

The SetDataSource method expects an object, like a DAO.Recordset or ADO.Recordset, not the path to a database file. Are you trying to pass a DAO.Recordset to the report?

For Each crxDatabaseTable In crxDatabaseTables
crxDatabaseTable.Location App.Path & "\database\db.mdb"
Next

[khandu]

well, it says invalid use of property for above also..

man..

[brucevde]

crxDatabaseTable.Location = App.Path & "\database\db.mdb"

Did you even try looking at the documentation? A little browsing and you would've found

http://devlibrary.businessobjects.com/BusinessObjectsXI/en/en/RDC_SDK/rdc_com_dg_doc/doc/rdcsdk_com_doc/RDC_ObjectModel260.html#1686406

[khandu]

I tried as suggested.. still the same error

Object variable or With block variable not set (Error 91)

on the above mentioned line..

can some1 please upload a small proj here showing how to select manual location of DB for CR11 reports in VB6 during runtime..
thanks

[khandu]

*bump* please help someone..

[brucevde]

I don't understand why the link posted earlier does not help you. I don't have CR11 so cannot create a sample app. Post your modified code...

This is what I use to do CRXI with VB6

On a form that hold the ReportVeiwer do the following:

In the Declations section of the form:

Private m_App As New CRAXDDRT.Application
Private m_Rep As New CRAXDDRT.Report
Public mRepName As String
Public mstrW As String
Public mstrUName As String
Public msRepTitle As String
Public mstrRef As String
Public mstrC3 As String

Private Declare Sub Sleep Lib "kernel32" (ByVal dwMilliseconds As Long)

Now create a sub Named DisplayReport:

Public Sub DisplayReport()
Dim ConnectionInfo As CRAXDDRT.ConnectionProperties
Dim strPNameP As String
Dim test As String


Set m_Rep = Nothing
strPNameP = mRepName
mRepName = App.Path & "\" & mRepName
test = gstrDBLoc & "\" & gstrDBName

Set m_Rep = m_App.OpenReport(mRepName, 1)
If strPNameP = "RempRep1.rpt" Then
m_Rep.RecordSelectionFormula = m_Rep.RecordSelectionFormula & mstrW
ElseIf strPNameP = "RempRep1_HB.rpt" Then
m_Rep.RecordSelectionFormula = m_Rep.RecordSelectionFormula & mstrW
ElseIf strPNameP = "RempRep2.rpt" Then
m_Rep.RecordSelectionFormula = m_Rep.RecordSelectionFormula & mstrW
ElseIf strPNameP = "RempRep2_HB.rpt" Then
m_Rep.RecordSelectionFormula = m_Rep.RecordSelectionFormula & mstrW
Else
m_Rep.RecordSelectionFormula = mstrW
End If
Set ConnectionInfo = m_Rep.Database.Tables(1).ConnectionProperties
On Error Resume Next
m_Rep.Database.Tables(1).DllName = "crdb_dao.dll"
ConnectionInfo.DeleteAll
ConnectionInfo.Add "Database Name", test
ConnectionInfo.Add "Session UserID", "Report"
ConnectionInfo.Add "Session Password", ""
ConnectionInfo.Add "System Database Path", gstrDBLoc & "\Security.mdw"


If strPNameP = "FSSResultsbyNuclide(Area)_New.rpt" Then
m_Rep.ReportTitle = "Sample Results by Rank"
ElseIf strPNameP = "FSSSamplesforAreaDetail_New.rpt" Then
m_Rep.ReportTitle = "Sample Analysis Results by Area"
ElseIf strPNameP = "DataFrequencyPlot.rpt" Then
m_Rep.ReportTitle = "Data Frequency Plot for " & fRepGen.cboIsotopes.Text
ElseIf strPNameP = "E600SurveysinArea.rpt" Then
m_Rep.ReportTitle = msRepTitle
ElseIf strPNameP = "DataQuantPlot.rpt" Then
m_Rep.ReportTitle = "Data Quantile Plot for " & fRepGen.cboIsotopes.Text
ElseIf strPNameP = "AreaComps.rpt" Then
m_Rep.EnableParameterPrompting = False
m_Rep.ParameterFields(1).AddCurrentValue (mstrRef)
m_Rep.ParameterFields(2).AddCurrentValue (Me.mstrC3)
ElseIf strPNameP = "RempRep1.rpt" Then
m_Rep.EnableParameterPrompting = False
m_Rep.ParameterFields(1).AddCurrentValue mstrC3
ElseIf strPNameP = "RempRep1_HB.rpt" Then
m_Rep.EnableParameterPrompting = False
m_Rep.ParameterFields(1).AddCurrentValue mstrC3
ElseIf strPNameP = "RempRep2.rpt" Then
m_Rep.EnableParameterPrompting = False
m_Rep.ParameterFields(1).AddCurrentValue mstrC3
ElseIf strPNameP = "RempRep2_HB.rpt" Then
m_Rep.EnableParameterPrompting = False
m_Rep.ParameterFields(1).AddCurrentValue mstrC3
End If

crView.ReportSource = m_Rep

Sleep 2000

crView.ViewReport
'crView.Zoom 1

If strPNameP = "AreaComps.rpt" Then
m_Rep.ParameterFields.Delete (1)
m_Rep.ParameterFields.Delete (2)
ElseIf strPNameP = "RempRep1.rpt" Then
m_Rep.ParameterFields.Delete (1)
ElseIf strPNameP = "RempRep1_HB.rpt" Then
m_Rep.ParameterFields.Delete (1)
ElseIf strPNameP = "RempRep2.rpt" Then
m_Rep.ParameterFields.Delete (1)
ElseIf strPNameP = "RempRep2_HB.rpt" Then
m_Rep.ParameterFields.Delete (1)
End If
Set m_Rep = Nothing

End Sub



That is called from the print but on the form I have to generate the reports. This use a security database and uses group security. But you should get the basic idea of how to do this here.

[khandu]

error is mentioned on top

[GaryMazzone]

What Error? At the top of what?

Did you include the references for Crystal as follows:
Crystal Reports Viewer Library 11.0
Crystal Reports ActiveX Designer Design and Runtime Library 11.0
Crystal Reports Activex Designer Runtime Library 11.0

[khandu]

yes.. all the runtime are included


I get the error on the line

For Each crxDatabaseTable In crxDatabaseTables

Runtime 424 Object required

some1 please modify the above code so that i can mention the DB location at runtime for the reports..

[brucevde]

Use the following code but place it after the report is opened, ie after
Set crxReport = crxApp.OpenReport(reportname)

Set crxDatabaseTables = crxReport.Database.Tables

For Each crxDatabaseTable In crxDatabaseTables
crxDatabaseTable.Location = App.Path & "\database\db.mdb"
Next

[khandu]

excellent.. repped and FINALLY RESOLVED!!!!

will put that code after all the report call..

THANKS A LOT!!
