Help..on passing params to Crystal reports from VB5

I am using VB5.0 and crystal reports 8.5 .
New to crystal reports.

could someone clarify some basic question please.
1. should I use "Crystal reports" control or "Crystal report viewer"
2. I have a report and I need to pass 3 parameter from my VB screen. How can I do that?

thank you

I think u should use crystal report viewer so that u can have select statement there. It will be easy to pass those parameters of your.

it's been a while since I used Crystal Report from VB, but I used
CR control:

with CR1
.Connect = "ODBC;DATABASE=mm;UID=abx;PWD=abx;DSN=hh"
.ReportFileName = App.Path & "\" & "myreport.rpt"
strSelect =" {mytable.myfield} ='abc' "

.SelectionFormula = strSelect
end with

Addition:

you have to set CR1.Action = 1 in order to view report

If you use the crviewer and need to pass more than one paramater in code here is what I put in the viewer

Dim crpParamDef As CRAXDRT.ParameterFieldDefinition

For Each crpParamDef In Report.ParameterFields
Select Case crpParamDef.Name
Case "{?Location}"
crpParamDef.AddCurrentValue (CLng(frmStartInvAssignVolByCo.txtLocation.Text))
Case "{?MasterCompany}"
crpParamDef.AddCurrentValue (CLng(frmStartInvAssignVolByCo.txtCoID.Text))
Case "{?StartDate}"
crpParamDef.AddCurrentValue CDate(frmStartInvAssignVolByCo.txtStartDate.Text)
Case "{?EndDate}"
crpParamDef.AddCurrentValue CDate(frmStartInvAssignVolByCo.txtEndDate.Text)


End Select
Next
--------------
The paramaters are input by the user on a form that preceeds the viewer

thanks a lot guys
