SOmething sounds funny. Remember any session variables will only be there for the duration of the session. Maybe the session gets reset somewhere  . Try adding breakpoints at session start/end events and see what happens....
Good luck

i got the answer for this one too.
After creating the WebService object, create a cookie container for it.
Suppose you web service name is xyz.ws
so the code in Session_Start will be
xyz.ws ws1 = new xyz.ws();
ws1.CookieContainer = new System.Net.CookieContainer;
Session["ws1"] = ws1;
Now you can get the same WebService session from this Web App Session using the session variable.
Nice talking to you though. Got me thinking on a lot of things. I work here alone and I need someone to talk to about tech stuff once in a while .

Thanx Thomas
Very helpful indeed.
O BTW , I spotted this website and downloaded it, but forgot about it ... DOPE!
http://samples.gotdotnet.com/quickstart/aspplus/doc/default.aspx[^]
When I was looking at it, it looked very helpful indeed, much better than the "few" examples on MSDN.

Thanx again I work from home, but prefer to work alone, with some online help. Unfortunately my free GPRS connection comes to an end this month, so daytime will be a bit lonely untill ADSL becomes available in my area (local peak phone calls are probably the highest in the world (i dont even want to mention the cost per MB for GPRS once this free trial ends  )).
Cheers

The code in the previous post is for the web application. Web service objects created in an app by default is sessionless ie, it does not store the cookies. We just create a cookie container and ,wow, it is like invoking from a browser...

So the only difference between a web app and a web service is how a session is defined?
|
|
|
|
|
When a web application becomes the client for a webservice, that has state, the web application should identify the session in every request to the web service. Normally, this does not happen because the Web application does not store cookies. But, the Web service proxy object inside the web application can store the cookie, if one is created by the user.
The web service by default does not manage states - because it is a performance overhead. So, we have to explicitly enable session support for each web method that needs it, so that the session is loaded for the particular web method call (an extra load which we ask the ASP.NET framework to do by the EnableSession=true directive).

If I make it static, will the static variable have app scope or session scope?
I wonder whether the value will be seen by all objects of the class, irrespective of the ownership

I declared my object as public static in the Global class and I could use it from anywhere. Now this is why I think it's not a good idea, security wise.

I have seen talk on google about setting the sessionState parm in web.config = "StateServer"
Would that help?
IMHO Stateful web services is kind of an oxymoron that opens up a large can of worms.
Can't you store your state in the registry or DB?

I found the answer:
On the line that says [WebService]
change to
[WebService(EnableSession=true)]
and it works!!!!

MS implemented tabs in VS .NET, a feature they ignored
in previous versions (good, old CBuilder  . But did they
forgot to add a build-incrementing function again?
(like the one in the good, old CBuilder)
(well in C# and .NET it could be something different but
I cannot figure it out in the C++ version at all - the
"classic one, the unmanaged one")
All the free add-in for VS 6.0, I tried, didn't work.
BTW I haven't seen the good, old CBuilder for years but I
feel that VS .NET reminds me very much the good, old
CBuilder.

Nope, well not in C#. Just go to Project Properties, Configuration properties, Advanced, set incremental build to true. Now, goto AssemblyInfo.cs and make sure the following looks like this:
[assembly: AssemblyVersion("1.0.*")]
Now the part with the "*" will auto increment.
NOTE: This is on by default for debug builds and off for release builds.
Hope this helps

does sombody knows why myDateTime.AddMinutes doesn't do anything?
i am trying to do:
DateTime myDateTime = Convert.ToDateTime("18/09/2002 13:00");

but nothing happen to this myDateTime??
thanks in advance, sharon

Try myDateTime = myDateTime.AddMinutes(40)
The Add... methods only return another DateTime, they don't modify the object. This is pretty much common across the .NET Framework.

Hi !
I'd like to know how can I pass parameters to an ActiveX in a c# windows application. As far as I know, the ActiveX control implements IPersistPropertyBag so that the container in html can pass the params through the Tag PARAM in the HTML tag OBJECT. However, I don't know how to do it within a c# application.
Please, somebody could help me ???
thx in advance,

Derive AxHost, you've got the following protected load methods :
DepersistControl();
DepersistFromIPropertyBag(IPropertyBag propBag);
DepersistFromIStorage(IStorage storage);
DepersistFromIStream(IStream istream);
DepersistFromIStreamInit(IStream istream);

Sorry but I'm quite new in c# and I don't know exactly what u mean, could u please explain it?
When I add my Ax control "myCtrl" in the aplication, I think Aximp.exe creates AxmyCtrl which is the wrapper for my control and is dervied from AxHost.
However, if I derive this class, I can't find the protected methods u talked about. I've looked in the help for the members of AxHost and I don't find those protected methods.
Could u tell me more exactly what should I do?
thx for everything,
ORi.

Using an ActiveX with .NET is achieved with one of these :
- you simply want to drag&drop the component onto a form. So yes, you import it from the Toolbox Window, and when you drop it, the .NET environment creates two wrapper assemblies (one for the ActiveX layer, one for the underlying COM layer). That's perfect as long as you just need to call methods, properties, and stuff. I would think that, once activated in a form, the ActiveX would by itself (I mean with no additional code) selfs depersists, hence load the previous state, but eh... who knows...
- the other solution is to bypass the wrapper assemblies, and derive the System.Windows.Forms.AxHost class. Once derived, you just need to implement a few methods to get this class actually attached to the underlying ActiveX. For more info on it, just googlesearch with "AxHost" : you'll find code. What I said in an earlier post is, once the class is derived, you may call one of the listed methods in the constructor (or any adequate place) to load the previous state.

Hi all
Anyone got any recomendations for a Static Analysis tool that can be used in C# to find bugs, glitches, inconsistencies etc - i.e. finding run-time errors at design-time?
Basically any info on something similar to PC-Lint used in C/C++ would be ideal.
Cheers.

You've got FxCop[^] for instance (see gotdotnet.com).

Hey I tried that, and I got so many errors in my code (cant remember what I was testing though), so I uninstalled it . Maybe a newer version is out, and maybe my code looks (is) better now. I'll give it a try again.
|
|

|

OK, so I got a @#$#load of errors again, though most of these "errors" are totally biased design "rules" (really only considerations).
EG all priority 1:
MemberNameKeywordCollision:
The member name 'Stop' conflicts in whole or part with reserved keyword 'Stop'. //yeah right, maybe with your code, but not with mine
EventHandlerNamesEndInEventHandler:
Rename 'BASSProgessHandler' to end in 'EventHandler'. //why make the name even longer, it wont effect the code.
EventFirstParameterIsNamedSender:
Change the first parameter of 'Progress' to an object type named 'sender'. // hell, i cast enough, why do i need to cast even more?
MemberOnlyShortAcronymsAreAllCaps:
Correct capitalization of member name 'get_ChannelEAXMix'. // again, who cares? EAX looks better to me than Eax (that looks more like some assembler function, maybe FXCop will complain about it too
ExceptionsRequireMultipleConstructors:
Add a constructor with a string parameter to custom exception 'BASSException'. Add a constructor with a string parameter and exception parameter to custom exception 'BASSException'. Add a protected constructor with a SerializationInfo object parameter and a StreamingContext object parameter to custom exception 'BASSException'. // again why? if you dont need it, why clutter your code with useless code?
TypeNameKeywordCollision:
The type name 'Error' conflicts in whole or part with reserved keyword 'Error'. // reserved????
MemberNamesDontUseUnderscores:
Remove the underscore from 'BASS_OK'. //if its not OK, why even make it legal to use?
ParameterNamesUseCamelCasing:
Instead of parameter name 'Length', use 'length'. // i cant help it if i hit my caps lock by mistake.
TypesDontExposePublicInstanceFields:
Make 'fWetDryMix' private or protected and provide a public property to access it. // Properties dont allways work when u need to "chain" a few, also the extra processing (repeated get/sets) makes it inefficient.
NamespaceNamesUsePascalCasing:
Instead of namespace 'nBASS', use 'NBASS'. //no, nBASS looks way cooler
and now for the 2 (yes only 2) usefull ones (priority 1):
AssembliesShouldBeStrongNamed:
Sign 'nBASS' with a strong name key. // not neccesary, but recommended.
MethodShouldKeepAliveIntPtrIfFinalized:
Add a GC.KeepAlive(this) to the method 'Void Stop()'. //i have no idea what they mean...does look like it could break my code though.
Any comments welcome
