Create a Connection String for DoseControl
The connection string that DoseControl will use to connect to the database will take the following form, and you will replace the highlighted portions with your system’s values:

1 If SSMS is still open, close it and reopen it. If not, you can launch SSMS from the start menu.
2 To get the Data Source value for your connection string, make note of the Server name (Data Source) that appears in the Connect to Server window. Based on the preceding steps it should appear as <YOURCOMPUTERNAME>\SQLEXPRESS (including the backslash). For example, the GEX test environment appears as WINDEV2010EVAL\SQLEXPRESS:

3 The Initial Catalog value is the name of the database where the DoseControl data will reside. It will be named GEXApp. (You can name the database whatever you want!)
4 The connection string’s User ID value is the Login gexapp that you created in the preceding step Configure SQL Authentication logins.
5 The connection string’s Password value was also set in the Configure SQL Authentication logins step. You must use the password that you saved in that step.
