Hi

I have made an application in Visual Basic that connects to SQL-Server without using a DSN. (just a simple connectionstring)

Now, if I want to make a Cristal Report it looks like I need to make a DSN.

Is there any way to work around this problem?  

Thans a lot!

Rosie,

Are you Using the Crystal Reports Control(crystl32.ocx)?

Could you post the Connect String that you are using so I could Have a look at it?

Cheers,

Ed.

if you want to set your connection string when you make a new report... when you select your database use these options:

more datasources/active data/active data (ADO)

select the ado and oleDB radio button
then put your connection string in the textbox

You can use a DSN less connection, just like you already have connecting to SQL-server.  Use the same connection string.  Add code similar to this:
-------------------------------------
sreport_name = "rpt_swap_valuation.rpt"
   
   sreport_name = App.Path & "\REPORTS\" & sreport_name
   
   Set crreport = crapplication.OpenReport(sreport_name)
   For i = 1 To crreport.Database.Tables.Count
       crreport.Database.Tables(1).SetLogOnInfo gServerName, gDbName, gLogin, gPassword
       crreport.Database.Tables(1).Location = gDbName & ".dbo." & "Get_Swap_Appraisal"
   Next i
   crreport.ParameterFields(1).AddCurrentValue (sreport_fund_num)
   crreport.ParameterFields(2).AddCurrentValue (CDate(sreport_processingdate))
   crreport.ParameterFields(3).AddCurrentValue (gFundgroupnumber)
   frmReport.rptViewer.ReportSource = crreport

   frmReport.rptViewer.ViewReport
   frmReport.Show

My first answer is for Elmo:
I haven no idea wich one... sorry
My connectionstring:
strSecConn = "Provider=SQLOLEDB.1;Integrated        
    Security=SSPI;Persist Security Info=False;" & _
    "Initial Catalog=" & strSecDatabank & ";Data Source="
    & strSecServer
where I fill the variables with values I read from an Ini-file.

To bobbit31:
I cannot find the options you specified ... sorry
I can tell you I have productn° 4.6.1.0 and CRW32 4.6.1.116.  Maybe an old version?

To Chess:
thanks, I'll try it right away!

Chess, I'm gonna need some more help.
Cause, if I open the Crystal Reports then I can only choose to create a new report before doing anything else.
Also: where do I put the code?

You can pass in the name of an existing report. In the code that I have posted above, "rpt_swap_valuation.rpt" is the name of the report.  It is using a stored procedure called "Get_Swap_Appraisal".

If you need to open the report based on some user action such as clicking a command button, then put the code in the click event of the command button.  

If you still need more clarification, please post your code in full.

ahh... you are using an old version of crystal reports.
I use crystal 8.0, so that's probably why you don't see the same options.  I don't know how to do it (or even if you can) in cr 4.6
