i have tried a whoel bunch of these tutorials and i have not got only one to work but thenCode:<connectionStrings> <add name="MyConsString" connectionString="ZONE777\SQLS;Initial" Catalog="newDB;Integrated" Security="True;" providerName="System.Data.SqlClient" /> </connectionStrings>
the display did not work.
if any one know of a tutorial that show how to store just the path of the image and then
store and display them with asp.net, I would greatly appreciate it.
thanks,
craig
