hye there
Well I know you have tried alot . but just for reminder.. you have to start your remote hosting application first. second thing is do not include the hosting application in your solution if you have hosted them on the other machine. make sure you have mentioned the ports and system name correct. test system name through ping command to confirm it is responding on network.
I have one test application let me search for that if I found I shall send it over. for testing you can use this CSharp as well

yes please send it over if you found it  . i'm not getting the exception(service requested is not found)anymore. however, it's still not working properly ...i don't know if it is me or the code given in the book. i'm newbie in .net remoting

Hi,
I am starting with VB.NET and I downloaded VS.NET 2005 BETA 2 (the full edition named "Team").
I already have an application written in vb.net (framework 2.0) and I'm not finding the way to put this script (msn alert) to work! 
http://www.codeproject.com/cs/miscctrl/taskbarnotifier.asp[^]
In the tutorial he says: First of all, copy TaskbarNotifier.cs in your project directory.
Add on the top of your source code the directive: using CustomUIControls;
1) Where I find the "top of my source code" ? I just can see the classes that I created in the code view.
2) What is a "member variable in my class" and how I set it up in vb.net?
3) Where may I edit my "constructor" ?
Thanks in advance!

.cs means C#. Can you mix and match C# and VB.NET within the same project in 2005 ? I thought you could only do that in ASP.NET projects ?
LPalma wrote:

Go to the source file where you want to use this class. I'm not sure how to say this without it coming off as sarcastic, but here goes - there is a scroll bar on the right of the screen, move it to the top.
LPalma wrote:

A variable that exists inside your entire class. So you define it inside the class, but not inside a method, and then the entire class can see/access it.
LPalma wrote:

Your constructor is the method that is called the same as your class. It gets called when a new instance of your class is constructed.
It sounds to me like you have a lot to learn before you start trying to use other peoples code. Getting something that looks cool up quickly may feel good, but if you don't know the absolute basics, it's a recipe for disaster. Buy yourself a beginner book on VB.NET ( a 2003 book will probably do ), and work through it before continuing this project.

Hi Christian,
First of all, thanks for the answer!
I'm using the "TaskbarNotifier.vb" file which is included in the pack. So, I'm not mixing C# and VB.NET.
The "top of my source code" which as I was talking about is that part hidden by default (isn't it?). Scrolling the bar like you are saying (I know you weren't sarcastic) I can just see the clasess that I wrote. I am looking for the code that VisualStudio creates automatically (Imports, the name of the form, title of the form, default icon for the form, etc...). I can't see it by just scrolling. Once I got to the code, but I forget how to access it.
About buying the book, I'm waiting for framework 2.0... because I think v1.1 isn't so complete and framework changed a lot from 1.1 to 2.0.
Thanks for your time.

OK, you said .cs file. You meant .vb file.

Yes, a using statement exists at the top, in fact, you should see a group of them. Search your code file for using and see where it takes you, that's where they go. IT's not THAT critical ( as in, they don't need to go EXACTLY there ), but they will be in a group at the top. You should only have one class in each file, in almost all cases.
LPalma wrote:

A lot of auto generated code is hidden behind a comment with a + tag. You can create these yourself with #region and #end region in your code, then you can hide a section of code by clicking the +. Never mess with this code though, if it's in a method. The designer auto generates this.

I disagree. Sure, it's getting better, but there's no reason to wait at least 6 months before you can start learning. PLenty of full features apps have been written with 1.0/1.1. Do you ahve the beta of 2005 ? If so, you can certainly buy books on it today.

Yes, I'm beta testing SQL Server 2005 and they give us VS.NET 2005 B2 and I find it interesting and I started creating simples applications for home use. One of them has already 1000 lines codes and it just work perfectly (Yeah, VS2005 is so ease that I could use it just knowing ASP 3)
However, as I never used so complete tool, I'm a bit dizzy with these names "Constructor, Imports, etc"... I'll try to find a book to learn the basics, I tried to skip the begin, but it isn't working. eheheheh.
Thanks!

Yeah, ASP.NET 2005 has a lot of automagic stuff built in, which means you can get a lot done, and still have no idea about programming. I see this as a bad thing, although so long as you do some study so you know what's going on, it's obviously productive to not need to write reams of code to get a little thing done.
Introducing Microsoft Visual Basic 2005 for Developers (Pro - Developer)[^] looks like a good book for you. Amazon also has one on SQL Server 2005.

Thanks for the book. I'll check with my local book store if they can import it (I'm not from USA, as you may have notice because of my English).

Ok, I am in the midst of planning a forms/reports app and need to get some good feedback on the thoughts. The app is supposed to be n-tier.
My thoughts are this;
1. There will be a thin-client.exe installed to the PC (Sorry no ASP.Net we tried!)
2. The VB.Net front end will talk to a SQL2000-sp3/4 backend.
3. The users will access the report templates from a central doc repository on the net.
4. The App will have a directory on the network where modules are stored that can be updated.
Now is there a simple/efficient way to put a function in VB that onstart it will compare a version number or something in it with a version on the server and if the server version is newer to download/replace it and prompt for restart?? I have seen this with other apps but am not sure what the development enviro for those are.
5. The users will have SQL/Table based authentication for the application based on 3/4 levels.
6. We will probably use ORM.Net/Olero to build out the DAL.
Thoughts, Suggestions or general comments would be greatly appreciated as this will be my first VB.Net application.
Thanks,
David
You are only as good as your last project.

What does 'we tried' mean ? Do you have reasons to want ASP.NET ? The main issue is that ASP.NET GUI will never be as rich as a winforms app.

If you use VS.NET 2005, then you can set it up to do this for you, yes. Otherwise, you'd have to store the version number somewhere, and then run a bootstrap program that checks the version number, downloads the file and replaces it ( you can't overwrite a file that is running ), and then runs it either way.

It sounds like you really know what you're doing, do you come to VB.NET from VB6 ? ( i.e. this is obviously not your first application )

Originally the Requirements Document we wrote favored a Web Server based platorm. But the clients IT staff balked at that. So we are now going to the desktop. The web would be the lowest maintanence option as it would require maintaining a single code point, and the app it self is pretty straight forward so hopefully it will go off well.

I wish we could, but as this is a federal client we can only use stable software. I have played with 2005 and like it quite a bit, just wish it was truly ready for prime time today!

A variety of minor things, ASP, ASP.Net/C# and VB4/5 and once upon a time VFP!
Thanks for the Info, now if anybody has any other thoughts I think we should be set!

Oh, OK. The client is the problem. Been there, done that.

When will you release though ? You can actually sign an agreement with Microsoft to let you release beta version code, so long as you update it on release. I'm suggesting that if you use unit and regression testing, you can be sure that versions you give the client during production are stable, and if the turnaround time is long enough ( say, 6 months minimum ), then VS.NET 2005 will be out by the time you hit your actual release date.
But I agree, it is a risky strategy.

Cool. Why are you going VB.NET instead of C# this time ? ( Not trying to make a case, just curious why the switch ? )

We actually are going to have a pretty short schedule, we expect to be rolling out the initial release in 2 months or less for client testing.

It's the client thing again, they want to maintain the app in the future and they don't like the C# aspect. I could do it faster in that, since my VB is really dated.

OK, definately not an option then.

VB.NET is really different to VB of yore, as well. I thought this may be the case, only because I've had the same experience, where clients assume VB is easy and VB developers are a dime a dozen, so they will get an app that's easier to maintain.
Good luck with your project, it sounds like you're headed in the right direction, anyhow.

I'm stumbling (yet again) and I need some help.
Here is the background/what I want to accomplish:
1) VB.NET project
2) Default page has a number of buttons which redirect to their respective URL's
One in particular I would like NOT to be visible unless specific users (AD DNS Admins) are hitting the page. This would need to be authenticated agains either an AD group or a <location path="..."> in my Web.Config file that I have set up so that only the AD DNS Admins 'can' access the page.
3) If the client is a member of the list in the web.config or specific group in AD, the button would then be visible.
How do I go about doing this? I have tried a number of things on the default.aspx.vb page within the Page_Load but to no avail.
Any help is greatly appreciated.
Regards,

What you're looking for is Role-based Authentication. This is a topic that is much too large to cover in the forums. I suggest picking up any book on ASP.NET to get a better description of what's going on and how to use it.

Dave,
Thanks!
Hopefully this isn't a stupid question, but can I use Role-based Authentication IN CONJUNCTION with Windows Authentication?
This web-app is used on our Intranet for AD DNS information maintanance and administration, so it utilizes AD credentials to authenticate (through a DL).
If I can use Role-based Authentication to make the "UpdateDNS" button visible when the AD DNS Admins access the default page, then that will work. Guess I'll have to dig through my reference book (ASP.NET Unleashed by Stephen Walther).

Yes. They're completely seperate from each other. Role-based authentication is setup and managed by you. You determine what the roles are and what access each of those roles has. It's up to you to determine which authenitcation provider to use. In your case, it's Windows and AD.
The AD authentication is done by you to determine if this person is who they say they are and if they're part of the Admin group. Based on this, you can setup the users website roles.
Good book, BTW. I have the 2nd edition...
