Dear,
I am in great tense regarding connectivity problem.here below I try to explain my problem.
#####################################

HTML

<configuration>
  <configsections>
  </configsections>
  <connectionstrings>
    <add name="ConStr" connectionstring="Data Source=(local)\SQLEXPRESS2;Initial Catalog=Accounts;User ID=sa;Password=sa" providername="System.Data.SqlClient" />
  </connectionstrings>
  <appsettings>
    <add key="ConStr" value="Data Source=(local)\SQLEXPRESS2;Integrated Security=SSPI;Initial Catalog=Accounts;User ID=sa;Password=sa" />
    <add key="SecurityKey" value="My_Encript_Key" />
    <!-- SQL Server connection string -->
    <add key="Conn" value="Data Source=(local)\SQLEXPRESS2;Initial Catalog=master;Integrated Security=SSPI;User ID=sa;Password=sa" />
    <add key="DateStampBackupFiles" value="True" />
    <add key="servername" value="(local)\sqlexpress2" />
    <add key="databasename" value="Accounts" />
    <add key="username" value="sa" />
    <add key="password" value="sa" />
  </appsettings>
  <databaseinformation name="data" username="sa" password="sa" servername="(local)\sqlexpress2" pvdr="SQLOLEB.1" databasename="Accounts" />
</configuration>

here two problems arise I have accessed connection like:

System.Configuration.ConfigurationSettings.AppSettings["ConStr"].ToString();

give error not found ConStr but when i remove

<databaseinformation name="data" username="sa" password="sa" servername="(local)\sqlexpress2" pvdr="SQLOLEB.1" databasename="Accounts"/>

this works fine
I need both work concurrently because I am using

XML

<add key="ConStr" value="Data Source=(local)\SQLEXPRESS2;Integrated Security=SSPI;Initial Catalog=Accounts;User ID=sa;Password=sa" />
    <add key="SecurityKey" value="My_Encript_Key"/>
    <!-- SQL Server connection string -->
    <add key="Conn" value="Data Source=(local)\SQLEXPRESS2;Initial Catalog=master;Integrated Security=SSPI;User ID=sa;Password=sa"/>

for data insert,delete other database works,but

<pre>&lt;databaseinformation name="data" username="sa" password="sa" servername="(local)\sqlexpress2" pvdr="SQLOLEB.1" databasename="Accounts"/&gt;</pre>

this one for crystal report
I am in deep fix,please some one help me to get out this problem
I will be really grateful
Thanks

Solution 2

Hi,

Instead of this line
System.Configuration.ConfigurationSettings.AppSettings["ConStr"].ToString();

use this one:

strConn=ConfigurationManager.ConnectionStrings["ConnectionStringName"].ConnectionString;

objSQLConn=new sqlconnection(strConn);

Note:

Here,strConn-->string variable to get connection string from web.config
