@Formula or @Command

I created a hotspot that opens a view on a database on the Domino server.  I don't want to specify the server name and database path because we will eventually move the database in six months time.  So what I want to do is use an @Formula to look for the server and database path instead of specifying:  "Server name/OU/O":"Database path.nsf"  Is there such a command?

The function is: @DbName

First string returned by @DbName is server name, second string is the DB path on server.

But you do not need it. If you open your view with [OpenView] than it is allways the current DataBase.
============================
Example: OpenView  
This formula opens the Reverse Chronology view for the current database.
@Command([OpenView]; "Reverse Chronology")
============================

Wath command do you use?

zdima,
Why you don't use the replica ID ?
Then it's not necessary to use the server name and database name.
Then he looks all the server until he found the database.
If you want to move the datbase, you make a replica from the existing one and copy it to the new destination.
After that, you can delete the database from the old place

Greets,

If you want to make code portable, you don't hardcode anything. Surely not replica ID's, since this will also make your code very difficult to maintain. (Try updating design of a database that's full of hardcoded replica ID's, I can tell you it's a pain!)

I'd go with zvonko.
Use
   @command([OpenView];"Name of your view")
for opening a view in the current database.

To get the server name use :
  @Subset(@DbName;1)
For the database path use :
  @Subset(@DbName;-1)

If you're using it on the web, you need to translate the returned path to a URL, so you need to replace spaces and backslashes like this :
  @ReplaceSubstring(@Subset(@DbName;-1);" ":"\\";"+":"/")

This last thing just FYI, from your question I can't tell if you're using a client or browser for your application.

For this reasons i always have a parameter document that will always store the destination database server and dbname path.  I dont use @DBname or hardcoded values i just lookup this parameter document for the server and the dbname.

When you move the destination db from one server to another or change the name of it, you just edit the parameter document and your application continues working as it were previously.

Good Luck!
Arun

How do you solve your problem with replica's?
If a person is working home on a local replica, and the database need information from another db's ?

If I good understand, then you write down the settings manual in the parameter document.
So, the users must have access to all the servers.
But if he's working home, he doesn't have any connection to another server.

Yes, I know that.
But, I'm  just asking, how do solve your problem if you're working home or on a other server.
Else you must explain it to me.
Where I work, we have databases, who're used over 60 countries.
Then I must specify for each server(coutry) a seperate parameter document.
If you use replica ID's than he automatically search to the database.

Put the replica ID in the configuration document and your problem is solved. Simple...

Arun,
I'm just starting out and not as advanced as you guys are in Notes so I need your help.  I like the idea of using a parameter document.  How would I go about doing that and defining it in the design of a database?
Thanks!
