connection-string

问题 Can anybody tell me the effective difference between the following connection strings: <add key="ConnectionString" value="server=tcp:192.168.0.12\Sqlserver2005;database=;user id=sa;password=;"> <add key="ConnectionString" value="server=192.168.0.12\Sqlserver2005;database=;user id=sa;password=;Network Library=DBMSSOCN;"> I believe both are effectively the same. Specifying "Network Library=DBMSSOCN" explicitly connects using TCPIP and prefixing server value with TCP does the same thing. Please

问题 This question already has answers here : How to securely store a connection string in a WinForms application? (2 answers) Closed 5 years ago . I'm working on a windows desktop program. This program will connect to a remote SQL server. It has a 3-tier architecture. So the Solution contains several ClassLibraries as well as a main Windows Form Application. I don't feel safe using connection string like this: string connStr = "Data Source=94.xx.xxx.xx; Initial Catalog=xxxxx; User Id=xxxxx;

问题 I have a child package where the ConnectionString property of a Connection Manager is set by a Parent Package Variable Configuration.

问题 I have a Web project which calls a library project (DataAccess) to retrieve some data from the database.
