ok Atleast can u tell me how can i implement in windows OS ?

If you are attempting to create a port scanner then I STRONGLY suggest that you consider the following.... Do not do this unless YOU own the network or you have PERMISSION from the owner of the network in WRITING to do this. People have been expelled from school, lost their network connectivity, been fired from jobs, have had civil judgments rendered against them and even criminally prosecuted because they did this. Even when they thought they had a legitimate need for the functionality.

What does any of this have to do with using C# to identify whether or not a port is open? *pre-emptive celebratory nipple tassle jiggle* - Sean Ewington "Mind bleach!

You need to create a custom action in your setup. This[^] should give you an idea.

window.location And FYI, it is unnecessary to state that your issue is urgent. It might even be viewed as offensive. Thou mewling ill-breeding pignut!

It still has to start to detect that there's another instance running. It's not that they don't stop the appearance of an app not being started again, but there will always be a finite period of time where the second instance has spun up - even if it then terminates.

Are you asking how to create a file association, so that when you are on the Desktop, or in a Windows Explorer window, and you context-click on a file whose type is the type you have associated: then you want the Windows system context menu to appear with the name of your application under the "Open With" sub-menu ? Have you set the left mouse button to be the context-click button ? When I consider the brief span of my life, swallowed up in the eternity before and after, the little space which I fill, and even can see, engulfed in the infinite immensity of spaces of which I am ignorant, and which knows me not, I am frightened, and am astonished at being here rather than there; for there is no reason why here rather than there, now rather than then.

This isn't a better way, just another way. It also isn't secure, it is possible to download free registry watchers to see what is being changed. Checking whether the system date has changed is a problem too, as this can be done via the BIOS. For .net apps there is no 100% way to secure against tampering, the best you can hope for is to stop the majority of users.

Is there any control in c# other than webcontrol to display the html pages.

Hi, Cake PHP is a framework for developing and deploying PHP appications. Its like some other frameworks like Joomla, Symfony. You can find more information here http://cakephp.org

You can use LINQ to XML which is probably the easiest and most performant way of doing it. (And it is this way that uses the XElement class mentioned earlier. They're are good tutorials on LINQ here at CP or on google. V.

InstallShield. Wix. InnoSetup. They all can manage this - it's a fairly fundamental requirement of installer applications. Forgive your enemies - it messes with their heads "Mind bleach!

1- What did you try (please post some code) ? 2- What do you expect ? 3- What do you get (and where in your code does it occur) ?

Depending on the situation, it may be appropriate (i.e. if the vast majority are valid and an invalid one really is exceptional). For UI validation it frankly doesn't matter but from a perspective of style you are correct.

I think you can use the function get_content($url) for get mode or post _content($url,$post_param) for post mode, you can see below. Calling another url page in the PHP page

BobJanova wrote: The file should be locked against reading when it is actually being written. In a document editing app, that should be the time between pressing 'Save' and the save completing. You make a very valid point there. However, the implementation holds some problems and I guess that's why it is the way it is now. I'm thinking that if Word would do that, and another program decides to start reading from the file (thus locking it temporarily for writes), any save or write from Word would have to wait until the other program releases its lock. Now, if it is a well behaved program, this might only take a few seconds, but then still, it adds a few seconds to any file write, which can be annoying. This problem you could work around by the OS caching the writes (or the reads) of the other program. Now, suppose the other program is not so well behaved and keeps the read lock for minutes. Then we have Word hanging, or if it's cached the responsibility of the OS to keep all changes to the file cached for a very long time. Well, I guess that it could work if the OS supported it. But only then. As it is now, any program that would try to be 'friendly' and release the lock between writes would become very vulnerable to IO-blocking by other programs. It could be done maliciously, for instance, to indefinitely halt execution of an application. It is indeed a tangent, but I find it interesting to think about the possibilities :)

Thanks. Lately, I see many univotes to my answers and posts. I raised my concern at the Site Bugs & Suggestions forum, it was rejected outright.
