Hi there,
Will only be able to help u unless u show us your code segment. Think abt it, hope to hear from u soon.
Hi Sashi,
I am working on large-scale project entitled as MIS (Marketing information System). As I told you that I am using Vb 6 as front end, Ms Access as back end and Crystal report 8 as reporting tool.
1) In the project it is required to save dealer’s photo, and it should be shown in individual dealer’s detail report, which will include his/her image. I had taken Common dialog box control to select image and display it in image control.
2) The size of database is very large then, which will be useful from the following?
i. to store image to database?
(But it makes database larger in size which leads to slower access)
ii. Saving path of image in database
To keep database safe I want to try the second option first. Instead coding directly into project, I want test the logic into small program first. As we know that by use of common dialog control we can select image and show it in image control. Also same path can be stored in database. Also we can retrieve the path from database and show it image control.
Until here all things are ok. Now problem is that how to show the image in crystal report. Usually we pass the fields directly to crystal report by sending sql-query to it.
Here is some code part from the project. I am using crystal report viewer control to show the reports.
Following is report module:
Option Explicit
Public Function SET_REPORT_OBJECT(strReportName) As Report
On Error GoTo ErrTrap:
Dim Report_App_obj As Object
Dim Report_Obj As Report
Set Report_App_obj = Nothing
Set Report_App_obj = CreateObject("CrystalRuntime.Application.8")
Report_App_obj.LogOnServer "P2SODBC.DLL", "esm", "", "admin", "cb10esm"
Set Report_Obj = Report_App_obj.OpenReport(App.Path & strReportName, crOpenReportByTempCopy)
Set SET_REPORT_OBJECT = Report_Obj
Exit Function
ErrTrap:
Set SET_REPORT_OBJECT = Nothing
Exit Function
End Function
Following is code to pass the Query string to the report:
cmdAddressLabelPrinting.Enabled = False
On Error GoTo ErrTran
Dim rptName As String
Dim strSQL As String
Dim strQry As String
If chkCourior.Value = 1 Then
rptName = "\rptCouriorLabels2.rpt"
chkCourior.Value = 0
Else
rptName = "\rptLabels.rpt"
End If
Dim StrFilterString As String
'''Code For Manual Selection of Parties
StrFilterString = rsParty.Filter
frmListParties.PrintType = "New"
frmListParties.Show vbModal
If frmListParties.PrintType <> "Done" Then
MsgBox "Cannot continue Printing." & vbCrLf & "No Parties To Print!", vbExclamation + vbOKOnly
Screen.MousePointer = vbNormal
If StrFilterString <> "0" Then
rsParty.Filter = StrFilterString
Else
rsParty.Filter = adFilterNone
End If
rsParty.Requery
cmdAddressLabelPrinting.Enabled = True
Exit Sub
End If
Screen.MousePointer = vbHourglass
'''Code For Manual Selection of Parties
If rsParty.RecordCount = 0 Then Exit Sub
strQry = " Where partyCode in ("
rsParty.MoveFirst
While Not rsParty.EOF
If strQry <> " Where partyCode in (" Then strQry = strQry & ","
strQry = strQry & rsParty.Fields("partyCode")
rsParty.MoveNext
Wend
strQry = strQry & ")"
strQry = strQry & "order by priority ASC "
Set mReport = SET_REPORT_OBJECT(rptName)
strSQL = "SELECT partyName,priority,partyAddress, areaName, CityName, pinCode, stateName, partyPhone1, directorName " & _
"From qryAddressLabels " ' & "ORDER BY priority ASC "
If strQry <> "" Then
strSQL = strSQL & " " & strQry
End If
If mReport Is Nothing Then Exit Sub
mReport.DiscardSavedData
'mReport.ParameterFields(1).ClearCurrentValueAndRa nge
'mReport.ParameterFields(1).AddCurrentValue Str((RegistrationFeeAmt + SalesKitAmount))
mReport.SQLQueryString = ""
mReport.SQLQueryString = strSQL
frmReport.CRViewer1.ReportSource = mReport
frmReport.CRViewer1.ViewReport
Screen.MousePointer = vbNormal
frmReport.Show vbModal
Set mReport = Nothing
If StrFilterString <> "0" Then
rsParty.Filter = StrFilterString
Else
rsParty.Filter = adFilterNone
End If
rsParty.Requery
cmdAddressLabelPrinting.Enabled = True
If you require more details, please let me know. I will make it available.
