Oh, I just love regex, it's an art form. Here's a regex which can validate (it's not mine, I found it on the web):
1. All valid dates from 1/1/0001 to 31/12/9999
2. Correctly validates leap years
3. It's valid for the regex classes on .NET framework
^(?: (?: (? ?[13578]|1[02])(\/|-)31)|(?: (? ?[1,3-9]|1[0-2])(\/|-)(?:29|30)))(\/|-)(?:[1-9]\d\d\d|\d[1-9]\d\d|\d\d[1-9]\d|\d\d\d[1-9])$|^(?: (? ?[1-9]|1[0-2])(\/|-)(? ?[1-9]|1\d|2[0-8]))(\/|-)(?:[1-9]\d\d\d|\d[1-9]\d\d|\d\d[1-9]\d|\d\d\d[1-9])$|^(0?2(\/|-)29)(\/|-)(?: (? [48]00|[13579][26]00|[2468][048]00)|(?:\d\d)?(? [48]|[2468][048]|[13579][26]))$
Remove all the spaces from it, I've added some to bypass the emoticons.

Who needs MSIL obfuscation when you've got RegExp. Of course, the trouble is you obfuscate your code to yourself

Was not sure what form this would belong to but since I code exclusively in C# nowadays and they will be written in C#, I thought I would try here.
What is the best way to send/receive binary data (like images or files) with web services? Just simply pass as a parameter or is there a better way?

Perhaps have a look at DIME[^].
"Direct Internet Message Encapsulation (DIME) is a lightweight, binary message format that can be used to encapsulate one or more application-defined payloads of arbitrary type and size into a single message construct."

sorry about the title...its a little long 
i have a quick question reguarding a program im working on. it is a simple text editor...(not much more complicated then notpad) its fine but the question is how do i add support for opening files. I.E when you double click a .TXT file notepad automaticly loads and load the contents of that file too the text field... how can i accomplish this ? if i was unable to explain this clear enough leave a post and ill try my best to clearify... thanks alot for your time
Jesse M
p.s im not talking about using a openFile dialog 
file associations with command line args ?

You can get at your commandline arguments using Environment.GetCommandLineArgs()
To register your program for a shell operation during install you need to add a reference to it in the registry key HKEY_CLASSES_ROOT\txtfile\shell. Have a look at what's already in there for some clues.

Does anyone know any good tutorials/references for packaging a windows form application that requires full permissions so that it may be started from a webpage?
What I am looking for is something that will allow me to do the following:
1) User clicks a link
2) Something pops up saying "do you trust this company" or "can this program have full permissions"
3) If permission granted, then the program is run from the user's hard drive with full permissions.
Any help or direction will be greatly appreciated!

This is not really what CAS (Code Access Security) is about. The whole idea is that people will run something, even if warned not to. The security model is placed solely in the hands of the admin to allow or disallow what code can run from where. The user is not asked.

I totally agree with you  . . . CAS is definately the way to go when under the supervision of an admin. However, for a home user with minimal knowledge of .NET security . . . I would prefer that the are just prompted for trust, letting me handle the rest. Much like how the Windows Update site works.
I believe this can be done with a signed CAB file and an embedded object in a web page. Does anybody know the pros/cons of this approach and where to find good .NET tutorials on the subject? I am slowly getting closer to a solution.

I remember seeing an article about this at:

Don't remember which one but I am sure you can find it while browsing there. It was a fairly indepth article.

Hi,
I'm adding some controls on Panel at runtime. This works fine, but after removing this controls, Application can't be closed (and Closing event isn't called). 
Creating controls:
MyControl ctrl=new MyControl();
ar.Add(ctrl);
panel1.Controls.Add(ctrl);
Removing all controls:
panel1.Controls.Clear();
foreach(MyControl ctrl in ar) ctrl.Dispose();
ar.Clear();
When I'm not removing controls it works 
i'm only pointer to myself

MyControl ctrl=new MyControl();
// MyControl is derived from UserControl
ar.Add(ctrl);
panel1.Controls.Add(ctrl);
You are duplicating code.....
Tomas Petricek wrote:
panel1.Controls.Clear();
foreach(MyControl ctrl in ar) ctrl.Dispose();
ar.Clear();
It seems the GC might be invoked too early, therefore modifying the collection while enumerating thru it, which is illegal.
Rather use a while loop:
while (Controls.Count > 0)
{
Control ctrl = Controls[0];
Controls.Remove(ctrl);
ctrl.Dispose();
}
Hope this helps

I heard somewhere that this can happen if controls are hidden.

There is a bug where a Form can't be closed if you remove a control that has the current focus.

Thank you !
Setting focus to another control solved my problem.

I'm very new to programming in general but if I get a push in the right direction I think I will manage. I'm trying to build a windows application that will output a sequence of keyboard/mouse presses. What I need to know is where in C# do I find the functions that outputs the pressing?

Not the only option but probably the easiest. Consider DirectInput, part of the DirectX 9 SDK[^].
Of course, the downside is that anyone who wants to use your software needs the DirectX 9 runtime, which is a 32Mb download. But if that isn't a problem, DX9 will do the job.

HI,
I am writing an application which actually connects to a oracle db hosted on a unix machine. There will be around 1000 desktop clients(win XP) hosting the application. Right now the database username and pwd are stored in app.config to connect to db. How can i hide these details from client mahine user? I mean how can i prevent desktop user to know the db passwords from config file..?
encryption is taking very big maintenance work, every time they change db password...each time they need to change the config file with encrypted passwod.
Webservice scenario doesn't work in this context as there are no web servers.
please help me finding someway
regards

Is it possible to send message to instant messengers using c# and asp.net
|
|
|
|
|
|
Thanks a lot for your response. My actual requirement is that I need to send alerts to the subscribers via various channels like mail, IM etc. In lieu with that, is there a possibility of sending messages to Windows messenger or the MSN messenger using the Interop feature or a built in feature of the .Net. The application would be on ASP.NET and C#. Is there any reference for the same.
