Hi everyone
I have a solution based on Secure Conversation using a Security Context
Token Service (which is just a web service) that gives out SCT's, a client
program gets the issued SCT. But the problem I have is can this client then
hold Secure Conversations with one or a number of other web services.
I have another web service the client signs and encrypts the message and
attempts to send the response to the web service but I get the following
error.
Error "System.Security.Cryptography.CryptographicException: WSE523: The
CipherData contents are invalid"
I have read that much between blogs and MSDN, im all read out lol, BUT! I
can call a web method within the SCTS web service from the client. From my
understanding from what I have read when the Security Context Token is cached
it is cached in the AppDomain for the SCTS web service now that explains why
I can call the Web Method from the client and it works but when I call the
second Web Service it cannot access the AppDomain cache to check the SCT.
THEREFORE through WS-SecureConversation does all your Web Methods which the
client will call and sign and encrypt messages have to reside in the SCTS Web
Service.
Or can the client call as many other Web Services that are required of
course that reside on the same Server (have seen the implementations for web
farms).
So please please put me out of my misery can a client have a
SecureConversation with more than one Web Service and if they can how?
Thanks in advance

I might be missing something here, but have you tried making each connection its own object? Instantiating several database connections as their own objects is the way that I get to multiple database connections.
I apologize if I am missing something and this is a stupid answer.

Just store the different connection strings, and create a connection every time you need it. .NET connection pooling will find out if there's already another "closed" open connection (when you close it, it's not actually closed until some time later) and reuse it. The connection string must be identical for a connection to be reused, but if you have 5 different databases, you'll have 5 pools.

Eaven the db names should be the same?
The thing is that I have a app with a TreeView and the treeview is populated with all db names and then in each db node with some info from the db, and when i click a node the app will use to get info from the selected db...
Until now this is the method I have used changein the string but when I create a new DB and try to insert it in the tre view i do the .clear() thing from the tree and the try to rebuild it again... and some errors apear i will be back with code and error text...
Sorry for my BAD BAD english...
Thx

Well, then just make sure that everytime the same node is selected, the same connection string is built. You'll have connection pooling working for each different connection string, but in you scenario, I think that's the best you can do.

Hi,
I have to create an attendentee-list in Crystal Reports.
Vertically I summarize the student-data (name etc). This is OK, but know I have to summarize horizontally all the dates for the classes and every cell of the grid you get needs a code.
I was thinking cross-tabs or subreports, but I still can't figure out how to do that.
Can anyone help me?
tnx!
(example: )
session1 session2 ... sessionn
student1 code code code code
student2 code code code code
student3 code code code code
...
studentn etc...
No hurries, no worries.

Taking the Ferrari example from above, it's very different "Give $100K USD" to "Give ideas on how to earn $100K USD"!! 
He could have meant that, but how are we supposed to know?

I think that an application using C# to output a message that says "Hello World" on both the CRT and a printer would be an impressive final project. Give it a go, and if you get stuck, feel free to post any questions here. Good luck!

What I did for my final projects was go to different departments through out the campus to discover what they needed written and then selected from that list. In the end I wrote a complete point of sale system for the bookstore. I had 9 months to work on this though so you may need to scale back based upon your skill set and time available.
Hope this helps

Hello All,
I fill arraylist with some elements and i need to remove the duplicate elements for the arraylist. How Can i do that?
Thanks

Wouldn't it be easier to check for duplicates on insertion?
You can do so by using the Contains method of the ArrayList.

Whats the "best" (most widley accepted) way to store user preferences in a way they can be read and written to?
I though of using .config and coding a way to write back to it .... but have since been told its bad programming practice to write to a .config.
May be the registry? but im using this program as a peice of portfolio work to show potential employers and im not sure they would want a slew of candidates code writing to somthing as volotile and not-so easily cleaned as the reg' .... or is this somthing they will expect?

IMO, the best way is whatever suits the requirements of the application. Do you want your users editing the config file themselves? Do you want the config information human-readable? Does your install program handle creating a registry entries? Are you installing your app as an "all-users" app and relying on Windows login to differentiate users, or does your app have a separate login? Is it a client-server app, where the user config might be on the server so the user gets his/her setting regardless of what client tmachine they are using?
It's more a question of requirements than the current fad. Hope that helps.

On the other hand, you don't want to analyse the problem to death and paralyze the whole project, so just use an ini file. The important thing is to abstract your option loading and saving, so that you can plug in the popular method of the day. Then, of course, you'll discover that the ini file format is just fine 99.9% of the time and there's no need for the overkill of registry, SQL, XML, etc.

try using a Database. Hopefully thats the widely used approach (if not file IO)
Hope this helps!!!

Take a look at the Configuration Application Block[^]. It's part of Microsoft's Enterprise Library. I used the Configuration Application Block in my last app. and it worked very well. Easy to implement, very flexible and a snap to set up and configure.
Cheers,
Drew.
