Create SYSTEM DSN Programatically if Exist then Overwrite the Existing Path
Hi Experts
I want to Create a SYSTEM DSN at RunTime
This would be in Sub Main or suggest me some better way
i want to take the Database path at runtime through
App.Path & "\" & "\Database\MyDb.Mdb"
Now i want a Function to Check and create DSN like this
NewDSNName = Abc
NewDSNPath = App.Path & Database
If NewDSNName = Any Existing Odbc DSN Name then
IF NewDSNPath = Current odbc DSN Path then
exit function
else
Over Write Same Available DSN Path = NewDSNPath
endif
else
Create a Fresh New DSN
endif
Please provide solution for both Acces & Sql server

This solution is only available to members.
To access this solution, you must be a member of Experts Exchange.
You may need to integrate the above code with the Registry APIs, which allow you to read and write into Registry. Just wait couple of minutes, i will do a mock example for you..
cheers ;-)

Good
its working
BUT Sorry ........ i just checked again the following
http://www.freevbcode.com/ShowCode.Asp?ID=502
its also working perfectly to overwirte
so no need for adding more complexity ... i am writing this for future readers
anyhow thanx ... A little more is ...
my Access Db is password protected BUT now i am facing problem in opening connection with this database. when i test the connection it shows invalid username password are path BUT i am actually gave proper path ????
Could U provide me the string for a password protected DB. with jet ole db 4
waiting

Frankly, i'm very not satified with the grade "C", any reason why will be good.

i have already tried these solutions BUT
Please Read the Question Carefully
i want to overwrite the path
what if Source folder is moved to another location and when the application runs again then DSN is there but path is not valid. i want to check and confirm that path each time.
so Please reply accordingly
