VB.Net crystal report connection string - vb.net

Question

I am using vb.net 2010 to develop my software. Also have crystal reports in my projects and things are working perfectly in my PC.
My problem is that I design the crystal report in my PC with wizard and my PC is not the server, then upload it to the server so it would be accessible to users. But when try to open report a connection problem to the database pops up. I know that is due to the connection property when I designed the reports in my PC.
How can I solve this problem.

Answer 1

It is showing the popup for giving userid and password. I want to give the server connection programatically.
i given the following code still it showing the popup
Private Sub CrystalReportViewer1_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles CrystalReportViewer1.Load
Dim cryRpt As New ReportDocument
Dim crtableLogoninfos As New TableLogOnInfos
Dim crtableLogoninfo As New TableLogOnInfo
Dim crConnectionInfo As New ConnectionInfo
Dim CrTables As Tables
Dim CrTable As Table
cryRpt.Load("E:\ColorLab1\colorlab\colorlab\rpt_bill.rpt")
With crConnectionInfo
.ServerName = "MAHESH\SQLEXPRESS"
.DatabaseName = "cc"
.UserID = "erp"
.Password = "123"
End With
CrTables = cryRpt.Database.Tables
For Each CrTable In CrTables
crtableLogoninfo = CrTable.LogOnInfo
crtableLogoninfo.ConnectionInfo = crConnectionInfo
CrTable.ApplyLogOnInfo(crtableLogoninfo)
Next
CrystalReportViewer1.RefreshReport()
End Sub
How can i solve this?

Add this code in the module(for common access)
Public Sub SetReportDb(ByVal ConnectionString As String, ByRef CrystalReportViewer As CrystalDecisions.Windows.Forms.CrystalReportViewer, ByRef reportDocument As ReportClass)
'Get SQL Server Details
Dim builder As New System.Data.Common.DbConnectionStringBuilder()
builder.ConnectionString = ConnectionString
Dim zServer As String = TryCast(builder("Data Source"), String)
Dim zDatabase As String = TryCast(builder("Initial Catalog"), String)
Dim zUsername As String = TryCast(builder("User ID"), String)
Dim zPassword As String = TryCast(builder("Password"), String)
Dim ciReportConnection As New ConnectionInfo
ciReportConnection.ServerName = zServer
ciReportConnection.DatabaseName = zDatabase
ciReportConnection.UserID = zUsername
ciReportConnection.Password = zPassword
'Assign data source details to tables
For Each table As Table In reportDocument.Database.Tables
table.LogOnInfo.ConnectionInfo = ciReportConnection
table.ApplyLogOnInfo(table.LogOnInfo)
Next
For Each subrep As ReportDocument In reportDocument.Subreports
For Each table As Table In subrep.Database.Tables
table.LogOnInfo.ConnectionInfo = ciReportConnection
table.ApplyLogOnInfo(table.LogOnInfo)
Next
Next
'Assign data source details to the report viewer
If CrystalReportViewer.LogOnInfo IsNot Nothing Then
Dim tlInfo As TableLogOnInfos = CrystalReportViewer.LogOnInfo
For Each tbloginfo As TableLogOnInfo In tlInfo
tbloginfo.ConnectionInfo = ciReportConnection
Next
End If
reportDocument.VerifyDatabase()
reportDocument.Refresh()
CrystalReportViewer.ReportSource = reportDocument
CrystalReportViewer.Refresh()
End Sub
Inside each crystal report viewer give the below code it will override the old connection with connectionstring
Private Sub CrystalReportViewer1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles CrystalReportViewer1.Load
SetReportDb(My.Settings.colorlabConnectionString, CrystalReportViewer1, rpt_inwardreport1)
End Sub

Answer 3

So to put this into a proper answer:
Your first problem is solved by creating the same DSN on your server that you have on your PC.
Your second problem can be solved using code that looks something like this:
connection.DatabaseName = [DatabaseName]
connection.UserID = [UserID]
connection.ServerName = [ServerName]
connection.Password = [Password]
or
myCrystalReport.SetDatabaseLogon("myUsername", "myPassword","servername","dbname");

Answer 4

I know this post is a few years old, but after struggling with these same problems, I thought I would add a variation of Mahesh ML's routine for MS SQL 2016 server.
A three things to note:
SqlClient.SqlConnectionStringBuilder is used instead of DbConnectionStringBuilder
zSecurity (added) for Window's authentication instead of database user
reportDocument.DataSourceConnections(0).IntegratedSecurity = True is needed when Windows authentication is used
Public Sub SetReportSQL(ByVal ConnectionString As String,
ByRef CrystalReportViewer As CrystalDecisions.Windows.Forms.CrystalReportViewer,
ByRef reportDocument As ReportClass)
'Get SQL Server Details
Dim builder As New SqlClient.SqlConnectionStringBuilder
builder.ConnectionString = ConnectionString
Dim zServer As String = TryCast(builder("Data Source"), String)
Dim zDatabase As String = TryCast(builder("Initial Catalog"), String)
Dim zSecurity As Boolean = Boolean.TryParse(builder("Integrated Security"), zSecurity)
Dim zUsername As String = TryCast(builder("User ID"), String)
Dim zPassword As String = TryCast(builder("Password"), String)
Dim ciReportConnection As New ConnectionInfo
ciReportConnection.ServerName = zServer
ciReportConnection.DatabaseName = zDatabase
ciReportConnection.IntegratedSecurity = zSecurity
If zSecurity = False Then
ciReportConnection.UserID = zUsername
ciReportConnection.Password = zPassword
Else
reportDocument.DataSourceConnections(0).IntegratedSecurity = True
End If
'Assign data source details to tables
For Each table As Table In reportDocument.Database.Tables
table.LogOnInfo.ConnectionInfo = ciReportConnection
table.ApplyLogOnInfo(table.LogOnInfo)
Next
For Each subrep As ReportDocument In reportDocument.Subreports
For Each table As Table In subrep.Database.Tables
table.LogOnInfo.ConnectionInfo = ciReportConnection
table.ApplyLogOnInfo(table.LogOnInfo)
Next
Next
'Assign data source details to the report viewer
If CrystalReportViewer.LogOnInfo IsNot Nothing Then
Dim tlInfo As TableLogOnInfos = CrystalReportViewer.LogOnInfo
For Each tbloginfo As TableLogOnInfo In tlInfo
tbloginfo.ConnectionInfo = ciReportConnection
Next
End If
reportDocument.VerifyDatabase()
reportDocument.Refresh()
CrystalReportViewer.ReportSource = reportDocument
CrystalReportViewer.Refresh()
End Sub

Hi guys i got the answer
Private Sub rpt_billform_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Me.CrystalReportViewer1.LogOnInfo.Item(0).ConnectionInfo.ServerName = "MAHESH\SQLEXPRESS"
Me.CrystalReportViewer1.LogOnInfo.Item(0).ConnectionInfo.DatabaseName = "cc"
Me.CrystalReportViewer1.LogOnInfo.Item(0).ConnectionInfo.UserID = "erp"
