[RESOLVED] Formula in Crystal Report 10

Hi

How can I pass the formula in Crystal Report 10 in VB.Net. Without formula I am using this method to call the crystal report.

Can anybody guide me how to pass the formula :

VB Code:

Dim fSalesReportViewer As frmSalesReportViewer = New frmSalesReportViewer
Dim gl_conReport As OleDb.OleDbConnection
Dim ConString As String
ConString = "Provider=sqloledb;Data Source=server;Initial Catalog=test;User Id=sa;Password=;"
gl_conReport = New OleDb.OleDbConnection(ConString)
gl_conReport.Open()
Dim CrReport As CrystalDecisions.CrystalReports.Engine.ReportDocument = New CrystalDecisions.CrystalReports.Engine.ReportDocument
Dim QueryString As String = "select * from CompanyMaster"
Dim CrAdapter As OleDbDataAdapter = New OleDbDataAdapter(QueryString, gl_conReport)
Dim CrDataSet As DataSet = New DataSet
fSalesReportViewer.MdiParent = MainForm
CrAdapter.Fill(CrDataSet)
Dim CrDataTable As DataTable = New DataTable
CrDataTable = CrDataSet.Tables(0)
CrReport.Load(Application.StartupPath & "\Reports\CompanyReport.rpt")
CrReport.Refresh()
CrReport.SetDataSource(CrDataTable)
fSalesReportViewer.ReportViewerSales.ReportSource = CrReport
fSalesReportViewer.Show()

thanks

It is batter for you that use the parameter for passing the value in the crystal report. See the code for parameter
make a parameter in your report then..... :wave:

VB Code:

Dim Report As CrystalDecisions.CrystalReports.Engine.ReportDocument = New CrystalDecisions.CrystalReports.Engine.ReportDocument
Report.SetParameterValue(0, "Parameter Value")

Hi
I change the report and add parameter (name) and pass the parameter in vb.net
like: CrReport.SetParameterValue(0, "Company Details")
but error message shown: "invalid repot file path"

thanks

Error showing it self that report path is not correct, check the report path is it at the location or not??

no, path of report is correct, if i remove the parameter than it work properly
and when i include the paramenter this error shown


thanks

Means Report Path is Incorrect .. Invalid Path Error is not related to the Parameter. ;)

Hi

VB Code:

'Dim DataSelect As New CrystalDecisions.Shared.ParameterValues
'Dim DataValue As New CrystalDecisions.Shared.ParameterDiscreteValue
'DataValue.Value = "Testing Parameter Value"
'DataSelect.Add(DataValue)
'CrReport.DataDefinition.ParameterFields("CompName").ApplyCurrentValues(DataSelect)
CrReport.SetParameterValue(0, "Test Parameter Value")

When run the system , it will ask the parameter value but i want to set the parameter value from code / get the information from form

Pls guide how to do this

thanks

asm

VB Code:

CrReport.SetParameterValue(0, "Test Parameter Value")

In above code Zero means thet the we are setting the first parameter value. So How many parameter you are using in your Report. You have to set the value of Parameter according to the Parameter Index.You can pass the parameter value according to the Parameter Name also. Like This

VB Code:

Report.SetParameterValue("ParameterName", "ParameterValue")

Set Parameter :thumb:

Hi
I have the accordingly but still ask for parameter value while running

VB Code:

'Name -- parameter define in cr reports
        CrReport.SetParameterValue("Name", "Test Parameter Value")

Is your report asking you to feed the value of the name Parameter?

Suppose the formula field name is "vbforums" and the value is "verygood" then it would be

CrReport.SetParameterValue("vbforums", "verygood")

yes , it is asking to feed the value

Parameter name is "Name" and the value is "Test Parameter Value"

CrReport.SetParameterValue("Name", "Test Parameter Value")

Quote:

yes , it is asking to feed the value

For which parameter?? Name??

check your Report, I think you are doing something incorrect

I change the crystal report parameter name to "ParamName"
But the problem is still remains .. it will ask to feed the data while running the report from vb.net.

VB Code:

CrReport.SetParameterValue("ParamName", "Test Parameter Value")                 'Parameter Setting

Are you using more than one parameter in your crystal report??

VB Code:

'If parameter in the sub report then
        Report.Subreports("SubReportName").SetParameterValue("ParameterName", "ParameterValue")

No, I am trying on main report there is no subreport.

Now I am creating a report in Cr which is contains more than one table but the problem is -- how can i define the table in vb.net for every table i used in cr.

Read last Post Of the Cr In VB.NET at My signature :thumb:

You means to say that i have create each tables in dataset by there names i add in crystal report.

But If i add a subreport in main report than how can i add the table for subreport

You are correct,but I am working on the sub report Also but it will take some times!!

Ok,
But the still i face the parameter value problem .. In parameter fileds -- add "Head"
and drap it to the report section, In report section it will show "?Head". I am not change any properties of format fields of "?Head". And call it in vb.net

VB Code:

Dim CrReport As CrystalDecisions.CrystalReports.Engine.ReportDocument = New CrystalDecisions.CrystalReports.Engine.ReportDocument
        Dim QueryString As String
        Dim CrAdapter As SqlDataAdapter
        Dim CrDataTable As DataTable = New DataTable
        Dim fSalesReportViewer As frmSalesReportViewer = New frmSalesReportViewer
        fSalesReportViewer.MdiParent = MainForm
        QueryString = "Select * from EmployeeMaster"
        CrAdapter = New SqlDataAdapter(QueryString, gl_Con)
        CrAdapter.Fill(CrDataTable)
        CrReport.Load(Application.StartupPath & "\Report\EmpTest1.rpt")
        CrReport.SetParameterValue("Head", "'Test Head Value'")
        fSalesReportViewer.Refresh()
        CrReport.SetDataSource(CrDataTable)
        fSalesReportViewer.ReportViewerSales.ReportSource = CrReport
        fSalesReportViewer.Show()
        CrAdapter.Dispose()
        CrDataTable.Dispose()

But the while running the report from vb.net it will ask to feed the data .

thanks
