Asp.net - Crystal Reports Viewer: Failed To Open The Connection Error
Jun 19, 2012
Currently I'm working on a piece of code that involves using the Crystal Reports Viewer to export .RPT files to PDF. My problem is that the code works on literally everything except the website I'm planning to eventually put it on.
When placed on the website it throws back the error "Failed to open the connection." which I believe is connected to the SQL Server connection that's formed in order to read data for the report itself.
The code itself is solid and works when used in a separate console application I built to test it whether said code is run on my local machine or on the server itself. It even runs when I test the website in Visual Studio's virtual host.
I've narrowed it down to being some sort of permissions issue, but I am not knowledgeable enough in the various permissions settings to figure out which ones specifically apply to this situation. It's worth mentioning that other pages on the website are directly connecting to the same database, but they are doing so directly through Linq instead of going through the Crystal Report Viewer.
So does anybody know which settings I need to modify in order to fix the connection error.An added note: One of the other suggestions is to make sure there's an ODBC DNS in place that matches the one being used by the code. I have created such a DNS already.

I am trying to generate crystal reports from visual studio..net 2008 and my database is created using SQL server management studio express 2005. I am getting login errors when using the OLE DB for SQL Server source. In studio express I use SQL server and windows authentication and I have tried leaving the user ID and password blank and putting in my login details but still getting the error. I have enabled multiple connections to the database.

this event works ok, but the problem is that I don't know what field was clicked. Should I use objectinfo or something else? VB.net won't recognize for example e.objectinfo.

I have some Crystal Reports connecting to a Sql Server db that I would like to detect whether the connection is trusted or whether I need to supply the log on info (reports are not supplied by me so I can't control the connect method). If I just blindly supply login credentials, it won't connect if it is a trusted connection.The following does not work:
oRpt = oCR.OpenReport("C:MyReport.rpt")
if oRpt.Database.Tables(1).ConnectionProperties.Item("Integrated Security") = True then
'trusted connection[code]....
It gives the following error:Operator '=' is not defined for type 'IConnectionProperty' and type 'Boolean'.
I cannot find how create a construct in vb.net for IConnectionProperty. I can't find any documents from Crystal that explain it.I am using Crystal Reports XI - Developer

I�m converting some Crystal reporting functions from VB 6.0 to VB .Net 2008, have reports up and running, and I�m not quite sure how to approach one aspect. The issue I have is most of the Crystal reports connect to a database and run a stored procedure. The connection properties are set up in the report usually pointing at the development region. At run time I need to be pointing to either development, user acceptance, or production. I know what environment I�m in from a configuration file but don�t know how to go about telling Crystal what environment and stored procedure to point at. In VB 6.0 it was:
CR1.Connect = "DSN=" & A.ReportServer & ";<<Use Integrated Security>>;DSQ=" & A.ReportManhattanDB
Where A.ReportServer and A.ReportManhattanDB contain the connection poperties. The stored procedure is passed via:

I have about 15 .RPT files on my .NET 2.0 site, and I recently changed to a new database server.I successfully changed the Datasource on 14 of those .RPT files, but on one, after making the change, I get "Failed to Save Document" when I try to save the updated report. I can change the subreport's Datasource, and save it just fine, but when I try to change the main report's Datasource I get that error message.I'm definitely doing a "Verify Database" at various times throughout the process, but that doesn't seem to help.

I have created a data source connection to an access db by using the wizard in vs2008. I have then used this as a data source for crystal reports. My user would like to put the database on a network and reference it there. Is there a way to set a new path for this data source during runtime?

I am developing an application that is using a Jet database (Access 2007). The database is local to the project (e.g., on the same drive and in the project directory). Any time I attempt to access the database (to create another DataSet, etc., via designer, etc.), I get the ubiquitous "Failed to open a connection to the database" with:
No error message available, result code: E_UNEXPECTED(0x8000FFFF).
Opening the Database Explorer and attempting to attach to the database results in the above as well. There are no apparent locks on the file, etc., and I'm the sole developer for this.

I have one PC whereby the OS has been installed on E: and it has no C: drive. Onto this I have installed my .Net 4.0 WPF Application which runs fine.
However, when I try to access a crystal report it gives the exception below. This user is able to access the report from its network location in windows explorer so I assume the act of asking Crystal to copy it locally is causing a problem?
Therefore, can anyone advise where the local copy will be created and/or how I can control this.

I'm using Visual Basic Express 2010 and SQL Express 2008 in Windows XP. At first I couldn't add a datasource (the .mdf file for the database) because of a "Operating system error 32" which I seemed to have resolved by giving myself full permissions for .mdf file (by right clicking on the file and going into properties and then Security) and restarting the SQL SERVER (SQLEXPRESS) service. The dataset for the database is in my solution explorer but when I right click on a table adapter to add a query and attempt to open up the query builder, I get the error in the title above.

Whenever I run my service it never responds, I know it isn't the service as I have one similar running in a different aspx file running. I've looked into it and it's something to do with the web.config file but I don't know where. I was given a small web config file however when you put it in the place it says it doesn't like one specific line of coding in it. This is the error I am getting:

I am creating reports in Crystal Reports that is integrated within Visual Studio 2008, and I noticed that some of the features are disabled. One is the ability to link tables with a Right Outer Join or Full Outer Join. I also cannot "Show SQL Query" in Crystal Reports. Is this something I can enable or do I have to purchase or upgrade?

Working on a Migarition(VB6 to VB.Net(VS 2005)) application, where some of the reports are loaded in the application. The VB application is using the Crystal reports version 8. While migrating the application, we used the Crystal decisions and tried to load the report. Few of the reports are working fine, few are giving error(like boolean is required here, This field name is not known etc..). For few of the issues we have regenerated the report in CR XI it worked fine and few are giving the performance issue, but few reports are giving the same error as "This field name is not known".
To load the report we followed the steps.
1. Based on the user access level, the report connects to different DSNs.
2. Applies the LogonInfo to the report.
3. Sets the datatable as the datasource to the report
4. View the report.
If we run the application to load the report, it's throwing error as "This field Name is not known. Error in file C:Docs~UserLocal~TempSampleReport{EE6CC25A-D216-496C-AA95-E2F0C61718C6}.rpt:Error in Formula '{ViewReport.field} ="AB'"This field Name is not known".For this I have tried changing the setdatabaselocation in database expert.Still getting the error.The reports giving the error are using a View in it's Query. Is it causing the issue?

We are running Crystal Reports on a Windows Server 2008 with .NET framework 3.5 SP1. I have seen many causes of the general error "The request could not be submitted for background processing." on other forums, however they tend to be persistent and repeatable affecting just a single report due to a specific formatting issue with a specific report.We are seeing this error with the below stack trace, intermittently. It affects multiple different reports we have. It affects one particular report more frequently than other reports. Once a report is affected the same error will often appear in multiple reports at approximately the same time eg. for the next 10 minutes.The same report run with the same parameters may work when run again (soon after) or the application may need restarting before the report can be successfully re run. These reports all worked previously without issue. No change in server or code seems apparent which would have precipitated this error. All code behind for this is VB.NET We have had difficulty reproducing it in test environments and upgrading to the latest version of Crystal has not helped at all.

I have a "MicrosoftReportViewer" on a form and a Combo box that lists the available reports (which will end up being dynamic in the end).
When the use selects an item from the list, the system loads up the correct report (populating any datasets needed) and then displaying it.Thing is, I can't get the viewer to change the displayed report, it just refreshes the first loaded report.
As you can see from the code below, there are two reports set up. I can get either one to be displayed if you select it first, sadly you're then stuck with that one!Currently they both use the same datasouce, so no need to mess about with that.
Private Sub ComboBox1_SelectedIndexChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles ComboBox1.SelectedIndexChanged
Me.viw_ShowAllRepairsTableAdapter.Fill(Me.RepairsSystemDataSet.viw_ShowAllRepairs)
[code]....
This just loads up the report that the viewer has set as the default, reguardless of the report selected!What am I missing? There should be a way to change the report being viewed and I don't really want to be having multiple viewers just to house multiple reports?
