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

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�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 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 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?

I'm writing a windows form application using vs2008. I need to connect to different SQL server express database files during runtime. There is a "how to do" video showing a technique for this
[Code]...
and then in the Form1_load sub and before calling the data adapter to fill data, insert codes below:
Dim strConnectingSting = NewConnectionString
My.Settings.RunTimeConnectionString = strConnectingSting
The method works but only for the first database. I found once adapter.fill is called and the connection to a database is established, the connection can't be changed.To do what I want, I have to create a startup project to call my main project. When I want to change connection, close the main project and start again.

I have developed a windows form application using VB.Net with data access layer using LINQ-SQL. I want to allow the database to be configured from the application. I have created a form for input and save the input details in an XML file.
I need to know how to configure the LINQ to start using the new configured database on startup. I have read in one of the threads here about dynamic allocating the connection string with the following solution to include in every file where the data context is instantiated. [code]...

I am using vb.net and SQL server 2005 I have a project with database classes which are generated from database objects. That is I add a dataset to the project and drag and drop a database object onto it. The problem with this is that I have to give a connectionstring which is stored in the code. This is ok while developing the application. But runtime I want to use another connectionstring, both for security reasons and because each user of the application will correspond to a database user (SQL) and shall have a corresponding connectionstring. Is there an easy way to do this without having to restore to plain all datasets and do everything myself?

I have read through some other post and haven't been able to find an exact answer that I am looking for. I have a connection string saved in my.settings that I am using. My database is residing on a server. Now I am going to have to install this application at more then one area and they will have the database on their server. What I am wanting to do is for the application when it is loading to search the network to find the database and return the connection string without the user having to do anything. I know with a web application you can search the machine you are on for the connection string without knowing its location but was hoping there was some feature like that to search the network to find it.

I have a Windows application that uses typed datasets. When setting up the datasets, Visual Studio asks if you want to remember the connection.
Before filling the dataset, I programatically change the connection string of each table adapter so that it will connect to the remote database. Before this operation, it is set to the local database since that is the one I am developing on.[code]...

I'm trying to add a datagridview in vb.net, but it does not allow me to change the connection string or the database that should be imported to connect to it. The only thing that I'm seeing is the previous ms sql database that I connected with datagridview and everytime I click the new connection, the window closes and it leaves me with the datagridview with the previous connection that I have. And its not applicable because, now I want to connect it with mysql. Not ms sql. Its some sort of a cache like feature in vb.net, how do I get rid of it. so that I can add the new connection for mysql? Do I need to reinstall visual studio 2008?

I am creating a VB windows form applications , the working can be summarized as users fills some form and data is saved in sql server database.Now the problem i am facing is that i have to deliver this as a setup file to someone, and that person will further distribute it to different users to run on their PC, what i am thinking is that the code once installed on other computers and executed will give errors because of the connection string of sql server db as it will not match with that computer . I know that if a distribute projects i can put connection string in app.config and every user can change it according to his/her machine .But as i am giving a setup file how to solve this problem

In my earlier project I was able to change the connection string during the app settings loaded event and it was successfully. When I try to do the same for a code library project, I am not getting the system.configuration.connectionstringsettings to work. Could you please tell if there is a work around for this, or else it is always better to write the sql code instead of depending on the adapters etc.
Additional information: Clients App is WPF with Vb. Database is SQL Server 2008 Code Lib would only be on server, slq connectiona and data retrieving and saving actions are stored in classes in code lib only. Code Lib would be used with WCF, wcf is used to share the classes only and classes have the data. WCF is hosted as a windows service on server used by NET.TCP

I am writting an application and I used Wizard to create DataSets which auto-created their own xml code. This code uses the saved in My.Settings Connection String. Being a setting with an unchangable 'Application' scope i cannot change its value at runtime.
The problem is that when I install the Application to my customer the Connection String will have to change (maybe more than once). So is there a way to change the Connection String used by these objects at runtime ?
