Typed DataSet in DLL points to wrong database!

RE: Typed DataSet in DLL points to wrong database!

set up a connection string in the web config of each site
<connectionStri ngs>
<add name="MyConnect ionString" connectionStrin g="Data
Source=sqlhost. server.com;Init ial Catalog=trepidu scom;Persist Security
Info=True;User ID=MYID;Passwor d=XXXX" providerName="S ystem.Data.SqlC lient"/>

</connectionStrin gs>

then create an appconfig name space:
using System.Configur ation;

namespace MyCompany.MyNam e.Dal
{
/// <summary>
/// The AppConfiguarati on class for the web.config file connection
string.
/// </summary>
public static class AppConfiguratio n
{
#region Public Properties

/// <summary>
/// Returns the connectionstrin g for the application.
/// </summary>
public static string ConnectionStrin g
{
get
{
return
ConfigurationMa nager.Connectio nStrings["MyConnectionSt ring"].ConnectionStri ng;
}
}
}
}
then in your connection
area
using (SqlConnection Con = new
SqlConnectionAp pConfiguration. ConnectionStrin g))
{
......
......
......
}
just be sure to includ a using MyCompany.MyNam e.Dal; at the top

There is a paren missing
it should be
using (SqlConnection Con = new

There is a connection string in the DLL that is causes me grief. It points

How can I re-use that DLL on different websites and have it point to

configurable in Web.Config??

Re: Typed DataSet in DLL points to wrong database!

Since each web site would have its own web.config, set up the connection
string in the <connectionStri ngs... element
in the Assembly, you would get the proper connection string with:

ConfigurationMa nager.Connectio nStrings["myConn"].ConnectionStri ng;

Your assembly would need to have a reference to System.Configur ation.

Re: Typed DataSet in DLL points to wrong database!

Where do I put the reference to connection string in the BL/DL Assembly?

Does it go in Project/Properties/Settings or app.config or in code somewhere?

AND

What Connection String gets used when just working on the BL/DL Assembly
when there is no website (during development)??

TIA,
George

Re: Typed DataSet in DLL points to wrong database!

Hi George,

As for the TypedDataSet(in class library project)'s connectionstrin g
problem, it is a common question I've seen. Actually, you can override the
connectionstrin g in your consumer application(asp .net or other desktop)'s
app.config file.

For example, in your class library, when you created type dataset, it will
generate the following section in the class library's app.config file:

===============

<connectionStri ngs>
<add
name="ClassLibr ary1.Properties .Settings.MYASP DBConnectionStr ing"
connectionStrin g="Data Source=localhos t;Initial
Catalog=MYASPDB ;Integrated Security=True"
providerName="S ystem.Data.SqlC lient" />
</connectionStrin gs>
===============

this is generated by the IDE for your typedataset. You can try adding such
a connectionstrin g entry in your calling application( the asp.net )'s
app.config file to override the default value(compiled in class library
assembly).

here are some former threads where I've mentioened something else about
such customziation of class library's project properties:

#app.config
