View 9 RepliesI have a connection string for my SQL database connection called my.settings.GCRConnectionString which was created when I created my dataset for the application.

View 4 RepliesI want to create a dataset.xsd in vs2005, and I am using access database, so I cant know where my client save the application. Hence I used application.startuppath() to get the application folder and appended "Datadb.msd" to the application.startuppath() so i got the target location for the access databse in client machine. Now to create crystal reports I need the dataset.xsd but while creating a new dataset.xsd it was asking the path for the access database, how to programmatically specify the connection string in dataset.xsd so that i can create a connection string. and use that dataset for creating crystal reports.
View 2 RepliesI have a vb.net 2010 windows forms application with a strongly typed dataset. I am storing the database connection path in a txt file so that the database's location may be changed in the future for whatever reason. The typical location of the connection is the read only app.config from what I gather. I have the datasets modifier set as public but I am having trouble finding how to access the connection object for the adapter.
View 5 RepliesI'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.

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
