Connection String for Access Database using a Web Service

Question

User112400174 posted

Hi

I need a connection string to connect the microsoft 2003 database with my ASP.NET webservice

When just making a website I used to use the following connection statement

OleDbConnection dbconn = new OleDbConnection("Provider=Microsoft.Jet.OLEDB.4.0; data source=" +  + Server.MapPath("~/db/SalesCentral.mdb"));

Now as I am using a webservice the Server.MapPath function is giving an error

Please suggest an alternative

Thanks

Server.MapPath should work.  Could you post the error you are getting?

I notice there is an extra + (plus) sign just before the Server.MapPath call.

You can create this tab in webconfig of your project then you can use it

connectionStrings>add name="ConnectionString" connectionString="Data Source=ABCD;Initial Catalog=abc;Persist Security Info=True;User ID=abc;Password=abc" providerName="System.Data.SqlClient"/>connectionStrings>

then you can use on page

string connStr = ConfigurationManager.ConnectionStrings["ConnectionString"].ConnectionString;

hope you are looking for this thing..

Find this:-

 

<connectionStrings>
    <remove name="LocalSqlServer" />
    <add name="LocalSqlServer" connectionString="data source=.\SQLEXPRESS;Integrated Security=SSPI;AttachDBFilename=|DataDirectory|aspnetdb.mdf;User Instance=true" providerName="System.Data.SqlClient"/>
    <add name="MainConnStr" connectionString="data source=.\SQLEXPRESS;Integrated Security=SSPI;AttachDBFilename=|DataDirectory|main.mdf;User Instance=true" providerName="System.Data.SqlClient"/>
</connectionStrings>

connectionStrings>
    <remove name="LocalSqlServer" />
    <add name="LocalSqlServer" connectionString="data source=.\SQLEXPRESS;Integrated Security=SSPI;AttachDBFilename=|DataDirectory|aspnetdb.mdf;User Instance=true" providerName="System.Data.SqlClient"/>
    <add name="MainConnStr" connectionString="data source=.\SQLEXPRESS;Integrated Security=SSPI;AttachDBFilename=|DataDirectory|main.mdf;User Instance=true" providerName="System.Data.SqlClient"/>
</connectionStrings>

You can reference this directly from code using:

[C#]
string connStr = ConfigurationManager.ConnectionStrings["MainConnStr"].ConnectionString;

[VB]
Dim connStr As String = ConfigurationManager.ConnectionStrings("MainConnStr").ConnectionString

Note that the namespace for this is System.Configuration so for a console application the full namespace is required.

Or you can reference this declaratively within the ConnectionString property of a SqlDataSource:

<asp:SqlDataSource ID="SqlDataSource1" runat="server"
  ConnectionString="<%$ ConnectionStrings:MainConnStr %>"
  SelectCommand="SELECT [au_id], [au_lname], [au_fname], [state] FROM [authors]" />

 Did you make sure the database cannot directy be downloaded when someone enters

http://www.yourdomain.com/db/SalesCentral.mdb

To prevent this, you better place the database in the App_Data folder. If you do, the Connectionstring will be:

"Provider=Microsoft.Jet.OLEDB.4.0; data source=|DataDirectory|SalesCentral.mdb"
