Hello,

I have developed a few crystal reports now I have write an ASP( I am new ro ASP) Application which uses the activeXViewer for displaying the report to the client. I have seen some code samples on the web and tried using the following code but am getting an error Object does not support the property or method. The error is at the line: "set Session("Options") = Session("oApp").Options". Also I am using Oracle 9i as the database. Can anyone help me out with this its very urgent.
Thanks

The Code I am trying to use is

<%@Language=VBScript %>

<%
reportname = "Report1.rpt"

'This line creates a string variable called reportname that we will use to pass
'the Crystal Report filename (.rpt file) to the OpenReport method.
'To re-use this code for your application you would change the name of the report
'so as to reference your report file.

'CREATE THE APPLICATION OBJECT
If Not IsObject (session("oApp")) Then
Set Session("oApp") = Server.CreateObject("CrystalRuntime.Application.9" )
End If

'This "if/end if" structure is used to create the Crystal Reports Application
'object only once per session. Creating the application object - session("oApp")
'loads the Crystal Reports automation server (cpeaut32.dll) into memory.
'
'We create it as a session variable in order to use it for the duration of the
'ASP session. This is to elimainate the overhead of loading and unloading the
'cpeaut32.dll in and out of memory. Once the application object is created in
'memory for this session, you can run many reports without having to recreate it.

' CREATE THE REPORT OBJECT
'
'The Report object is created by calling the Application object's OpenReport method.

Path = Request.ServerVariables("PATH_TRANSLATED")
While (Right(Path, 1) <> "\" And Len(Path) <> 0)
iLen = Len(Path) - 1
Path = Left(Path, iLen)
Wend

'This "While/Wend" loop is used to determine the physical path (eg: C:\) to the
'Crystal Report file by translating the URL virtual path (eg: http://Domain/Dir)

'OPEN THE REPORT (but destroy any previous one first)

If IsObject(session("oRpt")) then
    Set session("oRpt") = nothing
End if

set Session("Options") = Session("oApp").Options
Session("Options").MatchLogonInfo = 1

Set Session("oRpt") = Session("oApp").OpenReport(path & reportname, 1)

Set crtable1 = Session("oRpt").Database.Tables.Item("hosp_unit_al l")
crtable1.SetLogonInfo "icom", " ", "hr", "hr"

'This line uses the "PATH" and "reportname" variables to reference the Crystal
'Report file, and open it up for processing.
'
'Notice that we do not create the report object only once. This is because
'within an ASP session, you may want to process more than one report. The
'rptserver.asp component will only process a report object named session("oRpt").
'Therefor, if you wish to process more than one report in an ASP session, you
'must open that report by creating a new session("oRpt") object.

set session("oRptOptions") = Session("oRpt").Options
session("oRptOptions").MorePrintEngineErrorMessage s = 0

'These lines disable the Error reporting mechanism included the built into the
'Crystal Report Print Engine (CRPE32.DLL). This is done for two reasons:
'
'1. The print engine is executed on the Web Server, so any error messages
' will be displayed there. If an error is reported on the web server, the
' print engine will stop processing and you application will "hang".
'
'2. This ASP page and rptserver.asp have some error handling logic desinged
' to trap any non-fatal errors (such as failed database connectivity) and
' display them to the client browser.
'
'**IMPORTANT** Even though we disable the extended error messaging of the engine
'fatal errors can cause an error dialog to be displayed on the Web Server machine.
'For this reason we reccomend that you set the "Allow Service to Interact with Desktop"
'option on the "World Wide Web Publishing" service (IIS service). That way if your ASP
'application freezes you will be able to view the error dialog (if one is displayed).

' INSTANTIATE THE CRYSTAL REPORTS SMART VIEWER
'
'When using the Crystal Reports automation server in an ASP environment, we use
'the same page on demand "Smart Viewers" used with the Crystal Web Report Server.
'The are four Crystal Reports Smart Viewers:
'
'1. ActiveX Smart Viewer
'2. Java Smart Viewer
'3. HTML Frame Smart Viewer
'4. HTML Page Smart Viewer
'
'The Smart Viewer that you use will based on the browser's display capablities.
'For Example, you would not want to instantiate the Java viewer if the browser
'Line 200
'did not support Java applets. For purposes on this demo, we have chosen to
'define a viewer. You can through code determine the support capabilities of
'the requesting browser. However that functionality is inherent in the Crystal
'Reports automation server and is beyond the scope of this demonstration app.
'
'We have chosen to leverage the server side include functionality of ASP
'for simplicity sake. So you can use the SmartViewer*.asp files to instantiate
'the smart viewer that you wish to send to the browser. Simply replace the line
'below with the Smart Viewer asp file you wish to use.
'
'The choices are SmartViewerActiveX.asp, SmartViewerJave.asp,
'SmartViewerHTMLFrame.asp, and SmartViewerHTMLPAge.asp.
'Note that to use this include you must have the appropriate .asp file in the
'same virtual directory as the main ASP page.
'
'*NOTE* For SmartViewerHTMLFrame and SmartViewerHTMLPage, you must also have
'the files framepage.asp and toolbar.asp in your virtual directory.

Just thought I would help you out!

1.)"I have seen some code samples on the web and tried using the following code..."

I am not sure what code samples you have been looking at on the
web but instantiating the Crystal Report object in a Session variable is completetly a wrong approach and actually consumes more resources that making a call to the object only when you need it on every page/script.

Repeat, do not use a Session var to hold a Object just set the object at the top of the script like so,

Set crObj = Server.CreateObject("CrystalRuntime.Application.9" )


2.) Also use this instrinsic ASP object to pull the physical path instead of the Request.ServerVariables(..) method you were using in your script: Use --> Server.MapPath("/")

3.) As for you main error "he following code but am getting an error Object does not support the property or method..."

The problem here I believe is that even though you have instantiated (successfully?) the Crystal Reports object in a Session var, you are trying to make a call using the Session("Options") var, which has NO WHERE in your script been remotely tied to an object or declared as possessing a value whatsoever. If you are trying to give the variable Session("options") the returned value of object method Session("oApp").Options then you would simply do this:

or better yet like I mentioned before do not use a Session variable to instantiate an object us simple vars like the example above to look like this


That should be a solid answer for you. Also going through your code, you would easily see an error on the following line if you ticked out the IF..Then statement and left the Set Session("oRpt") = nothing because ASP will look for an object.

Best of luck.

Cheers,
Christian

Thanks for the reply!
I had found some code examples at business objects that directed me in the same way your response did. I was able achieve my goal.

Thanks!

I have been having the same issue. Can you help me out with this? I am a bit confused on what you were saying...

I have earlier posted a reply on the following location for Crystal Reports Version 9. The database I used was oracle 9i. I used the examples given by business objects to use with the RDC of Crystal Reports 9.

I hope this link gives you the answer. If not give me specific errors may be I can help!

Ros1188

The following link provides with examples when using CR10

http://support.businessobjects.com/c...spzone_default

Ros1188

none of those worked for me.

hi,..
i've download sample code from url you gave (sample code to use crystal report 10 in asp), but when i try to execute...i just get white blank display monitor, without any data show off, 'n there isnt any error message too. This what make me confused :( do you have any solution for me ?

thanks

koecrit,

Which one of the several examples given was used by you?
I donot see any difference in the code. It is identical to the code given with the examples for cr9, Most probably the way in which you are providing the database authentication is wrong.

Also put your report with in the same folder in which you have placed all the other files from a particular example(say Begin Here). You may even try putting the DSN name and the Database Name before providing your user ID and Password. If you are using oracle then teh database name should not be provide ie supply the DSN, UserID and Password only not the database name in the asp code.

Are you able to execute Begin Here example correctly after downloading it or getting the same type of error?

hi ros,
thanks 4 reply...

i already extract source code i've download from url u gave, then make new virtual directory and pointing to directory where i extracted the ASP code.

Yes, the report is still in the same directory with asp file, i dont make any changes in the file. when i try to execute "BehinHere" example(just execute without change on the file), i dont get any data displayed, i just get white blank display monitor without any error message. When i try to execute the report itself, with crystal report 10, i can see the data displayed.
This what make me confused, is there i've to setting with my browser ?
for your concern, i use IE 5.

i wait for your solution, i hope it can solve my problem.

thanks you, ros
