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.
for example,
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?

I can tell you that it is possible... I have done it before, but I can not seem to find the information I had on it, sorry.
Gooky

Good to Know but sad that you didnt find the information about it. Mayby some one else in here knows how to do ?

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[^].

Okay, but is there any easy way to get my C# programs to work Active in a HTML document? it have to be an activa page.
As i mention before i know that Java and Flash is perfect to this job, but i reayl like C# and want to use that instead.

Aside from what mav said, there is also audio support built into DirextX. Check out the list of things you can do with DirectX audio here[^].

when i execute the following Query in Query Analyzer,it return 61 Rows.But it return 91 Rows in DataSet.
Query:
"set dateformat dmy select distinct T.DepNo,H.TranNo, H.TranType, T.ChqDepNo, H.TranRef, H.TranDate, T.BankCcy, T.ExRate, T.LAppAmt, T.AppAmt, H.IsReconciliation from tblCashHdr H,tblMultipleTender T where H.BankCode= T.BankCode and T.BankAcct='121105' and H.MerchCode='001' and H.TranDate <='13/09/2004' and H.TranDate>'01/01/04' order by H.TranDate"
Pls Help me,

I'd say your date comparisons are interpreted differently. Are you sure your "set dateformat dmy" is handled correctly in your program?

Hi,
is there any possibility to call a method by Name?
Example:
<br />
private void Run()<br />
{<br />
string vMethod = "Form1_Close";<br />
string vParam1 = "";<br />
string vParam2 = "System.EventArgs.Empty";<br />
<br />
RunMethod(vMethod,vParam1,vParam2);<br />
}<br />
<br />
public void RunMethod(string AMethodName,params string[] AParameter)<br />
{<br />
}<br />
<br />

You'll have to use reflection for that. You need a System.Reflection.MethodInfo object of the method in question (can be retrieved using Type.GetMethod()) and then call Invoke() on the result.
Regards,
mav

As mav pointed out, you will need to use reflection. Here is a quick example to get you going:
MethodInfo mi = typeof(Form).GetMethod("Close",
BindingFlags.Instance | BindingFlags.Public);
if(mi != null)
mi.Invoke(this, null);

1.) Why do you ask a CPP question in the C# forum?
2.) Why don't you give a file to include at the very start of your code?

It looks like your app referenced a version of Crystal Reports (9.1.5000.0) and the version of Crystal Reports that's installed on the machine your running your app is different. You must have the same version of the .DLL's on the target machine as what you developed your app against.

I create a object which inherits from TextBox class,I hope no contextMenu display when click mouse right button in the new object. How to cancel the event or cancel the contextMenu !
|
|
|
|
|
Create a new ContextMenu without any items and assign it as the ContextMenu for your TextBox like this.
private void Form1_Load(object sender, System.EventArgs e)<br />
{<br />
ContextMenu cm = new ContextMenu();<br />
myTextBox1.ContextMenu = cm;<br />
}
|
|
|
|
|
Actually it would be better to do this within the class, that way you don't have to worry about it if you want to do use it again somewhere else.
public class TextBoxEx : TextBox
{
ContextMenu cm = null;
public TextBoxEx()
{
cm = new ContextMenu();
base.ContextMenu = cm;
}
}
