I had decided to publish the following code into
PSC since I'm having looking for it for weeks and I had not found any similar
code and explanation in whole Internet. The following code is really a
compilation of dozens of manuals, codes, forum messages and so forth. I hope it
could be usefull to you. If you agree, please vote...
HOW TO OPEN AN EXTERNAL CRYSTAL XI REPORT IN VB6
1) You must enable the "Crystal ActiveX Report Viewer Library 11.0" in the
CONTROLS tab of PROJECT - COMPONENTS. A new object will appear in the VB6
TOOLBOX section (the REPORT VIEWER ocx).
2) Create a new form named "FRMCRYSTAL" (frmCrystal.frm) and add the Crystal
object into it. The report viewer window will appear inside your form. Put the
following lines in its LOAD event:
CRViewer1.Top = 0
CRViewer1.Left = 0
CRViewer1.Height = ScaleHeight
CRViewer1.Width = ScaleWidth
Set its "VISIBLE" property to FALSE and close the form.
2) To open and display an external Crystal XI report, you may use these lines
in any place of your program:
I'll divide the task in 4:
2.1) point and open the report;
2.2) change the report parameters;
2.3) change the report SQL query; and
2.4) view the report.
2.1) Let's open the external file.The second parameter ("1") means
NO-EXCLUSIVE open or TEMP-COPY open.
If you change for zero (EXCLUSIVE), the report will open just once per session.
Dim MyApp As New CRAXDRT.Application
Dim MyRpt As New CRAXDRT.Report
Set MyRpt = MyApp.OpenReport("c:\windows\sample.rpt", 1)
2.2) Let's change some parameters. Interesting to note the FORMULAFIELD
syntax, where I can name my text-fields instead to utilize their indexes (easier
to work on than the Business Solution's Crystal manual). Obviously, the
name between parenteses must reflect the exact formula/text/field name. In that
example, the formulas are STRING type.
MyRpt.ReportTitle = "That's my Title!"
MyRpt.FormulaFields.GetItemByName("InitialDate").Text = "'Initial Day: " &
dr1(0).Value & "' "
MyRpt.FormulaFields.GetItemByName("FinalDate").Text = "'Final Day: " & dr1(1).Value
& "' "
2.3) Change the report SQL query...
x = 100 : y = 1000
MyRpt.SQLQueryString = "select * from dropouts where InitialIssue <= " & x & "
and FinalIssue >= " & y
2.4) Finally, log on your server and database. Since your report already
exist and has the appropriated fields and layout, you must use the same database
and login info present in the report. In my example, you must change the names
for your correct ones.
"<database>", "<login>", "<password>"
' And voilá !!! Show the report!!!
frmCrystal.CRViewer1.ReportSource = MyRpt
' Clear memo...
Set MyRpt = Nothing
Set MyApp = Nothing
