can't get an answer to a crystal rpt question re database connection - Cor, Herfried, Armin, Ken Tucker?

[Bernie Yaeger]

I can't believe that there aren't lots of developers who:

1. create a crystal report that connects to sql server
2. calls the report using the crystalreportviewer control to view it and
then, if appropriate, print it
3. tries to deploy that report to the client's database, but now it calls
for a different database name

Yet I can't get an answer to the question:
I have developed numerous reports in an app (Windows Database App) that is
soon to go into production. When I built each report, CR connected to sql
server on my development platform. The connection string is different than
it will be at my client.

How can I change the connection string so that it recognizes my client's
server instead of mine for each of these reports?

Of course, I could install a version of crystal on the client and rebuild
the reports there, but that seems a terrible pain - and for every customer
with sql server? I've written to crystal and I get links to unhelpful kbase
articles.

Thanks for any help.

Hello Bernie

You can use the SQL-DMO ListAvailableSQLServers to
retrieve all SQL servers on your client. If there's only
one then use that one if not ask the user which one to
use.

And when you define the ConnectionInfo of the report you
can use .ServerName = <your variable>

As addenda to what i say.

All MS SQL Servers have a Master database.

You can use the following command :
<code>
Use Master
exec sp_databases
</code>
That will return all databases on the server and there
size.

You still need to have the database admin password on
your client to run this.

I have gone through this, and the following code circumvents all of the known bugs that I worked through to resolve the problem. Apparently there are more obvious ways to handle this that simply don't work (or didn't when I wrote the code)

I store connection information in a 'Registration' dll file that is located on each client. That way I can have an identical application running on many different clients, and each uses it's own set of connection info to get to the appropriate server and database. You could also use application settings that the users can change themselves

With this in place, I can create or revise reports on my dev machine and simply copy the report file to any and all clients with no changes at all, which was the main goal. The clients do not need Crystal Reports, and you certainly don't have to build the reports for each client

One note: this particular method will not work if you use Windows Integrated Security to connect the report to the database on your dev machine. So, if you used Integrated Security, and you want to use this code, open each report, change the database connection to use a UserName & Password, and re-save it. I informed Crystal that it would be really nice if this could be changed at run-time, but I am not aware if they have accomplished this yet

Hi Mark,

Finally, the right answers!

I had gotten some hard-to-understand suggestions in this direction from
Crystal, but the settings would not change using code very similar to yours.
I had just been guessing that the reason it wasn't working was because of
integrated security, and your remarks confirm that.

Now the last difficult part - how do I change from integrated security to a
login/pwd connection? Please let me know at your earliest convenience - and
thanks so much!

Hi Mark,

Nevermind - figured that out.

Once again, thanks so much - major headache gone.
