Accessing Database with Crystal report incorporated in VS2008

Hi,

I have a problem accessing the password protected database with some crystal reports which i use in my Windows app (written in C#).

The thing is that when i open a crystal Report it asks me for the password for the db, although i set it in the wizard when creating the connection. It only asks the first time after starting the app, after having entered the correct password all CR's open without the prompt.
When i check the properties window for the CR the field behind Password is empty. I thought it might be a security precaution, but in the end the CR does ask for the authorization when opened up, so my guess now is that the password isn't saved.
Is there a (secure) way to hardcode the password somewhere (like i did in the connectionString for the app itself), and if so, where?

Any help is heartily welcome...

Have you tried building a new connection in CR?

Over and over again.
My password just doesn't seem to stick...

I'm gonna try and make a new CR and see if at the creation there is a checkbox to check.

Crystal doesn't save the password for security reasons.  If it did then anyone who got a report file could gain access to the database.

As far as I know there is no way to save the password.

That's what i thought aswel, but why then is there the whole secure connection part in the connection setup?
Maybe i need to secure my db differently, it's just that It isn't my field of expertise.

What do you mean the Secure Connection part?

What we did was use the Integrated Security but that was with MS SQL.

When you call the report from an application you could pass a userid and password.
Another way would be to build the report against a dataset and have the application get the data and pass it to the report

I like that idea, to link the CR to the DataSet.
Just tried it out, but the fields don't show in the Report.

Any idea's?

Hi... Sorry for the delay.

I'm struggling with the tutorial now.
Although it is very easy to understand, the insertion in my existing project is a bit more difficult.
I am encountering several problems which are i think due to the fact that my solution is made up of 3 layers (projects) which are connected by reference, so that the layout layer (with all my forms) is not directly connected to my Data layer (where all connections with the database take place), but are separated by a relay layer.
It's a bit of a puzzle, to find out where i can make openings for the reports to connect to the Schema.
This message just to report that i am working on it, that i have not (yet) abandoned the subject.

Finaly got it done!!!

Thanx mlmcc! Her's your well earned points, sorry for the wait...

Needed some time to get the idea that i needed to pass the whole Dataset to the CR. And then i took some time to figure out how to get the path right to get the Dataset, safely, to that Report.

After hard work and brain crunching the reward is the biggest!!!

Thanx EE!
