Please tell me about how can i use TAPI 3.X in managed codes or C#. I want to make a project like PABX which route, record and dial calls and persist on hard disk.
Please send me sample code, articles or book names etc.
Thanks You

There may be problems using TAPI 3, however there is a sample for using TAPI 2 in C# on GotDotNet here[^].

I periodically have 2 odd things happening within Visual Studio 2003; both regarding the forms designer. I belive both are VS bugs, but there are no updates available for me to pull down and I was wondering if others have seen this behavior before:
First, within the solution explorer, sometimes all of my form files will get their icons changed from the little blue form to a green c# class file. Once this happens, any attempt to open a form will result in only opening the code. If I simply make a tiny edit to the base class name within the class definition and then change it back (change Form to Form2 and then back to Form), the icon fixes itself and then I can edit the resource.
The second odd thing I sometimes see is that a form that I had been editing 2 minutes earlier suddenly reports: An error occurred while loading the document. Fix the error, and then try loading the document again. If I simply close Visual Studio and reopen it, then I'm able to edit this form.
Has anyone else seen this oddity?

Is it possible to create a VS.NET addin providing a feature similar to Microsoft's IntelliSense? I don't want to add it inside a textbox in a project of mine, but inside the VS.NET code editor.
I got lost in the extensibility reference. Which events should I listen to to react to code editing?

Yes, there are companies that create such a product, Whole Tomato[^] comes to mind. There are many articles on MSDN and CP that cover writing add-ins, do a seach and see what you come up with.

Your statement makes little of no sense, could you reword it and ask again. Do you have a specific C# question?

For example: There has a thread in my application. I run my application's two instance on my machine at the same time. The thread need work normally if it is actived,be contrary to, the thread need not work.

hi,
I am in a big problem now. I despiratly want help from your side. i will explain what is my intension.
I developed one product (duration more than an year). Now i am faceing serious piracy problem. It is my bread and butter(It is my own product). so i can't leave this sort of piracy as simple.
First Problem.
I want to re-design my product which will run only for 20 times after installation. I least bothered whether user will use 20 times in a day or 20 times with in a month or 20 times in an year. It won't work after 20 times.
What is the perfect method which will keep a step ahead from all registry editing or date changing or anything which help the end user to extend the functionality of this product more than 20 times. Please tell me how can i achive this from my product's piracy issue.
Second Problem.
I will burn my product into a CD and i will gave it to the customer. Once he installed this product he can't even re-install it again. (If the user got any problem on the time of first installation.Then i will replace the CD). What i mean is if he try to install after 20 days or something it won't even allow the user to complete the second time installation.
One more thing is there A customer may have more than a computer which may or may not in a network. My requirement is, after the first installation the software i need to block the new installation on same machine ,new installation on another machine which may or may not in same network, new installation of any machine which is formated and installing as a fresh.
For acheving this i need to put some logic in CD apart from the Setup file. I don't know what sort of software i need to burn on the time of burning the setup file.
Please help me out.

No such thing... No matter what you use to protect your software, it will be broken within a month of your releasing it...
There is no one product that will give you all of the functionality your talking about. You can Google for "developer application copy protection expire" and come up with thousands of products, issues, and hacks for them, to "protect" your software.
It'll take you at least another year to develop a solution on your own. The issues and methods are just too complex...

hi,
This is called suggection. i don't need suggection , i want small tips or idea or any lead to get a solution. What you wrote is right.
Why hackers are hacking software ?
For the above question you will get different answers.
How hackers are hacking ? This question is importent.
Answer is simple " they are putting little more innovative idea to hack the software ".
according to me they are the right programmers.
Our discussionis different. so i am not getting into hacking or craking s/w.
In current IT worl nobody is taking effort to find a technologies hidden part.
Every one wil find what the product manual says.
It's too very bad.

You've contradicted yourself. What you need is a suggestion to find your tips and ideas. What I gave you was a starting point to do the massive amount of research your going to have to do to find solutions to your requirements. There are no "small" tips or ideas for these copy protection topics. Each technique to protect your software has it's pro's and con's and is much too large a topic for discussion in the forums.

I didn't say you were getting into hacking, but to understand the threat your software faces, you need to get into it to see the techniques used against your security solution and defend against them.

Oh yes there are people who do this! They're called "hackers"!

Hey SreejithNair,
Dave Kreskowiak told you his view trying to help you. He wasn't offensive in any way, just did not deliver the answer you expected, so please stop such remarks! 
I can only second Dave's point: What you're wishing for is simply not achievable at the moment nor practicable if it were.
You're wishing for a copy proof CD destroying itself after installation. Come on, get real!
Your program is supposed to find out if it's installed on a different pc that's not even connected to the one it's running on? How is it supposed to do this? I guess you'd have to ship a crystal ball with every CD...
And can you imagine what your regular customers-to-be will tell you when they find out that the installation CD is unusable after one installation attempt? This would surely keep me from purchasing your software and look for an alternative!
As Dave said, everything you can come up with can and will be cracked eventually. If you want a tip, here it is: A cracker knows as much about computers/programming/... as you do, usually even more. So it will always be a race between the two groups.
Your goal should be to keep everyday copiers from doing so with reasonable effort.
In every copy protection/licensing scheme there's a point where you have to check if the program is copied/licensed/whatever. This MUST boil down to only a few assembler ops: JEQ or JNE and simply replacing them switches your copy protection/licensing logic => Crack found, no matter how complicated your protection mechanism is.
Since you're posting to the C# forum it's even easier for potential crackers: CLR code can be decompiled and also obfuscators have their limits.
You could invest a year in developing what you think is the world's best copy protection scheme, but until that day you're not selling a single copy.
How much do you make in a year?
How many copies of your software have to be pirated (by people who would otherwise actually pay for your program!) to make up for the year you spend developing the copy protection?
Just do some calculations to see that searching for a perfect copy protection for an individual is more or less clueless.
Regards,
mav

Hi,
much answers and not helping you aren't they?
I had the same problem, and solved it.
There is NO way to really protect software on a "software" based
copy protection. Even windows xp and 2003 are beeing hacked, so,
forget about it.
If your software is a "low budget many customers" thing, i don't
know a solution.
If your software is "high budget" with lesser customer, think
about dongle-protection. www.rainbow.com can help you in this matter 
(there are a lot of companies who provide dongle protections, rainbow is well known).
My produced software does NOT leave my office without dongle protection anymore.
Dongle lost: 14 days grace period and asta la vista...
ofcourse for registred customers, they will get it replaced.
Good luck

Hi all,
I need to display two sets of records.
The second one should come under the first set of records and also second one uses the first one's unique id.

My table looks like this.
link_id, name, link, category
I need to display a datalist with the category and the links that belong to that category.
So, How to Do it?.
thanks in advance.

Hey!
I am about to make an online game.
I want the game to be runned in a HTML page, and it needs to be an active page(ASP.NET is not the solution).
JAVA and Flash whould probley work, but i realy want to work with C#, so is it posible to use ActivX to display a Program made in C# right in a HTML page not just C# controls?
And if so, where can i find information about this?

It's important to understand that ActiveX and .NET are two entirely different and distinct technologies. You could embed an ActiveX control within an application written in C# targetting the .NET Framework by wrapping your control using the AxHost class, however that's not really what your asking. You can also create href executables that download the assemblies and store them in an assembly cache on the local machine. You must be aware of code access security when trying to execute an href executable however, there is information about this on CP and MSDN. Chris Sells has an example of an href executable on his site at sellsbrothers.com[^].
