VS 2010 Dataset Connection. Where Can Change It In The Program

Jul 22, 2010

I have a dataset that I created through the wizard, to pull the data and their types from the database tables and prevent some of the headaches of creating the tables and data types individually.I am looking for where the database connection for the dataset is defined at so I can change this. The reason being is I have added a database connection dialog where the user will select the location of the database server and I am wanting to pass the connection string from what the user selects to the dataset so the dataset uses this as its connection string instead of the default one I defined in the wizard.Where is this defined at so I can change it?

Change Connection String At Runtime For Strongly Typed DataSet?

Jun 28, 2010

I need to be able to change the connection string of a strongly typed dataset at runtime. I have gone into the settings.vb page and written this code:

Namespace
My
'This class allows you to handle specific events on the settings class:
' The SettingChanging event is raised before a setting's value is changed.
' The PropertyChanged event is raised after a setting's value is changed.
' The SettingsLoaded event is raised after the setting values are loaded.
' The SettingsSaving event is raised before the setting values are saved.
[Code] .....

The way the code is suppose to work is that when a user logs in, the application gets the user's site ID (gvUserSite), then uses that to set the connection string. But when I log on with a SiteID of "21" it always uses the Case Else value. Also when I set breakpoints in settings.vb the application never stops on the breakpoints I set during runtime. As if the breakpoints were never set. Also if I put any code in the "MySettings_SettingChanging" in settings.vb I get a runtime error
"The debugger cannot continue running the process. Process was terminated.

Change Connection String Saved In My.Settings In Program?

Jan 30, 2012

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 ?

C# - Ignore Dataset Schema In WCF Connection?

Nov 2, 2011

On the server side of my application I have a function like this:

public function GetDS as MyTypedDS
Dim dsRetVal as new MyTypedDS
'Make fantastic things with the dataset
return dsRetVal
end function

On the client side I call this function through a generated "service reference":

Dim ds as Reference1.MyTypedDS = myRefInst.GetDS

How can I disable schema serializaion of the typed dataset to reduce the traffic?Is it enough to set the SchemaSerializationMode of 'dsRetVal' to ExcludeSchema before returning it? Or is this option ignored by WCF?

Can't Get Dataset To Pickup New Connection Info?

Aug 6, 2009

I have created many datasetsets in many projects in a solution. In each case the datatables reference a named data conection such as laptop_rick.intPricing.dbo. In that connection I point to the server, etc.. I should point out that in the code I connect to an entire different db server and this is all setup at runtime, this is strictly an IDE issue. Now I have moved the development server. Now of course when they try to connect to the server during development of the datasets it complains that it can't find the server. No problem just open the defined data connection and change the server name.

The problem is that I can't seem to get the dataset to recognize that it needs to rebuild that information in the xsd file. I look in the file and there are still references to the old server. If I change the connection definition in the xsd and rebuild all is fine but I don;t want to have to do that for each every dataset. It seems that although the dataset recognizes the name of the named data connection instead looking for that it embeds the details of the connection into the dataset xsd file.

Program 2010 Not Getting "created" Values From Stored Procedure With Dataset

Aug 11, 2011

I am using VB.Net 2010 and calling a stored procedure with a dataset to get values in a table plus "created" values.

The values for the "created" values do not come across from the stored procedure. They all show as zero in the IDE and False for the variables. I know I am getting the record because the first five values come across from the stored procedure into the variables correctly.

When I step through a VB6 program using ADO the values are pulled across from the stored procedure.

The problem seems to be in the interface between a dataset and "created" fields in a stored procedure.[code]...

Update Dataset Source Without Sql Server Connection?

Dec 16, 2010

I have an existing project written in VB.NET using Visual Studio 2005 communicating to a SQL Server 2005 database. The database was migrated to a sql server 2008 r2 on a different physical server so the dataset's server name needs to be updated. I do not have access to the database anymore. is there a way to just update the server name without invoking the dataset wizard and requiring a connection to the database?

UPDATE: I tried to created a new project with just a button with the command calling the following subroutine to test the connection from a windows app to the sql server database. here is the sub:

Public Conn as New ADODB.Connection
Public Sub PubSubConnectToDB()
Conn.Open("Server=w2k54

I am able to created a system dsn on the same server with the same credentials and test the connection successfully.

Strongly Typed Dataset Connection String As Variable?

Strongly Typed DataSet Connection String At Runtime?

I'm sorry but Microsoft did not think about this very well. I have used the dataset wizard to connect to my sql server and the connection string was placed in the app.config file. The only problem with this is that you can not write to it nor change string at runtime. So I need a way for each one of my users to specify their connection either during installation or after installation. I would appreciate any help in this matter.
