No, such a concept doesn't even exist. There is no "alternate" time/date source without checking a standard clock on the Internet. If the user doesn't have an Internet connection, you're out of luck.
Just checking the date/time isn't good enough. You have to get VERY creative at storing and using the date and time information and using it to determine when your app was installed, when the last run was, and what the current date/time is. All I can say is that you have to get VERY creative.
No, I can't tell you how I do it!

its really fun
if i unplugged the internet every time while i use the application then wat will be the case.
every one cannot be creative they will follow the standard method if u have some idea tell it will be usful . not the exact one but ideas can be shared.
i am not creative but that was my own idea.
we cannot restrict the user more
i crossed across a doubt till now i dint get any solution as i am not good in programming
that doubt is if we install ms word or vs2005 etc it will ask the user to enter the licence code for continuing the installation how its done so i can make my application setup wilth license code
another doubt is if you try to install a software it will ask you for administrative rights without administrative rights that user cannot install the product how to achive this one
till date i am searching for the solution do you have any idea

This is what's going to keep you from protecting your applications. You simply don't have the background to implement a security system yet.
There's is no one method to do this. There are many, many different ways of doing this, each a reflection of the person who wrote it. Most are easily defeatable. The rest are defeatable with some work. None are going to protect your app 100%.

You don't. Installations require administrative rights for many reasons.

Like I said, if I tell you how I do it, I defeat my own protection scheme. There's no way anyone is going to tell you.

can i add dll reference of project that create on framwork 2.0 to a project that created on framwork 1.
i tried to add reference of a project that craeted on VS 2005 (Visual studio) to project
on VS 2003 and i got error message that claime that assembly is not valid even due i tried to add a dll file.
please advice

hi dude
i am not clear with your question but to my knowledge it will be because of higher version to lower version thats from vs2005 to vs2003 and frame work.
its common in every language

No, you can't. YOu can go the other way though. This is because the framework tries to maintain backwards compatibility, not forwards. The code in the .NET 2.0 DLL project will most likely only work under the .NET Framework 2.0. You can NOT load two different versions of the .NET CLR into the same process at the same time.

Thank you very much!!!!!!!!!!!!

I think so no coz there is not much backward compatibility ..

I am using VS2005 object browser to explore unfamiliar concepts, but even after reading some help files I am still groggy on GetLifetimeService(). Can someone tell me when this would be used and to what end?
I think I understand it in a web context but I am looking at the instance in MarshallByRefObject base of a Windows Forms dialog box component.
Regards.

Given a MFC process and a .NET service, how does the MFC process communicate with the .NET service?
Which IPC should I use?
Thanks.

Hi,
I have a C# code snippet using thread and delegates which works fine in debug mode i.e. with break points and the same code doesn't work in run mode. I am running this on Windows XP 64 bit OS and .net 2.0. Any help in this regard is appreciated.

I presume by "run mode" what you really mean is "Release"? Or are you taking the debug build and running it outside of Visual Studio?
Also, it helps if you post the snippet so we can see what is going on. Saying it "doesn't work" is somewhat vague and unhelpful.

In Debug some values will be set to default values while in realse it may be assigned with null. Code depending on those may give some error also. Pls check for #if Debug kind of directives in this case the could will only work in debug mode never in release mode

No it won't.
An integer will be assigned 0 by default in Debug and Release. A Boolean will be false in both. A reference type will be null by default in both debug and release.
Can you cite any example where an object is assigned one value by default in a Debug build and another in Release?
|
|

|

Thanks to correct me. Then only we can check for #if Debug .in this case.

Dont hesitate to be a little bit more specific, so we might be able to help.

Do you have any threads running ? Are the bugs UI related ? I often find that breakpoints can make code work, because it will force a break which causes things to work where otherwise they face a race condition, or where a paint message gets lost due to too much processing happening for it to occur, that sort of thing.
What is the nature of the bug ?
