what is this mean?

Object reference not set to an instance of an object. Dim MyConn As New SqlConnection(ConfigurationManager.ConnectionStrings("psmConnectionString").ConnectionString) how to solve it?

Well, at a guess you need to add psmConnectionString to your config file. Christian Graus - Microsoft MVP - C++

i did put it on the config file.this is the line: appSettings add key="psmConnectionString" value="Provider=.NET Framework Data Provider for SQL Server:Data Source=HAPPYFAM-B614E1\SQLEXPRESS;Initial Catalog=psm;Integrated Security=True" appSettings is it rite? -- modified at 2:49 Thursday 23rd February, 2006

>>Dim MyConn As New SqlConnection(ConfigurationManager.ConnectionStrings("psmConnectionString").ConnectionString) What makes you think that the psmConnectionString item in the config manager will have a connection string property ? Why is it in the ConnectionStrings collection ? I didn't know there was such a thing, but assuming that there is, I'd assume that you need to do something specific to get your config item to appear there. Christian Graus - Microsoft MVP - C++

You have put the value in the appSettings section and try to access it in the connectionStrings section. Either move it to the connectionstrings, or access it using the AppSettings collection. --- b { font-weight: normal; }

when i used the conMyData = New SqlConnection(ConfigurationManager.AppSettings("psmConnectionString")) it has an error.the error is The ConnectionString property has not been initialized. the program stop at Myconn.open(). anything can i do??

You have a colon instead of a semicolon between the two first properties in the connection string. --- b { font-weight: normal; }
