There is nothing native in the .NET Framework to modify the Access Control Lists on Files, as far as I can find. You would have to use calls into the API to accomplish this. It would require writing up a couple dozen structure and function headers:
LookupAccountName, InitializeSecurityDescriptor, GetSecurityDescriptorDacl, GetFileSecurityN, GetFileSecurity, GetAclInformation, EqualSid, GetLengthSid, InitializeAcl, GetAce, AddAce, AddAccessAllowedAce, AddAccessDeniedAce, SetSecurityDescriptorDacl, SetFileSecurity, ...
then there's the structures that go along with them:
SECURITY_DESCRIPTOR, ACL_SIZE_INFORMATION, ACL, ACCESS_ALLOWED_ACE, ACCESS_DENIED_ACE, ACE_HEADER

I'm currently writing a painting method of an custom usercontrol. Is there a way to determine if the control is in designing state or at useual (runtime state) ?
public void PaintObject()
{
if (DESIGNTIME == true) DrawRectArountControl();
else DoUsualDrawing();
}
|
|
|
|
|
Sure, try using base.DesignMode().

What the problem really is, is that I wanted to store a function inside a namespace instead of a class, but that appearantly cannot be done. I have several very different classes witch all must use one function. I feel it would be waste of memory if I just drop the function to each class, or create an seperate class called something like MyFunctionsStoreClass that would store all the functions I might need. Is there an alternative ?

Yes, methods need to be inside a class. If you don't need an instance, you can add the word 'static' before the function declaration (like in 'static void blablabla()') and use it by calling ClassName.blablabla(), without the need for an instance.

In C#, yes. In IL, you can have global functions. I just include this for posterity. You're right about C#.

In VB.NET you can also have global functions.

Hi Guys,
I'm new to socket programming. I need to create a C# program that reads data from multiple servers at the same time or one at a time - whatever is the easiest way.
I have more than a 100 ip address and ports (from the list), If I can't connect and read from the first (IP and port) the program should go to the next IP/PORT from the list and connect and read the data. After that all data retrieved will be saved into the SQL server database.
If you could redirect me to some tutorials or samples it would be of greate help. Or if YOU could help me I would appreciate it very much.

There is actually a pretty good simple "chat" example in MSDN. I would recommend downloading it. It also never hurts to get familiar with the System.Net namespace.

Tom,
Do you have any specific site from MSDN regarding CHAT? I'm sorry but I really need the answer because of the pressure from my boss.

In my MSDN Oct 03, in ".Net Samples- How To: Networking" there is a sample simply called "Chat" with documentation and suplemental information. The exact same page is available online at http://msdn.microsoft.com/library/default.asp?url=/library/en-us/cpqstart/html/cpsmpnetsamples-howtonetworking.asp
I found it simply by doing a search "chat". No divine inspiration...I just knew a chat example existed somewhere.

Hi Tom,
You're really great with your help.
I've already created a socket program in c# and it was working fine. I just need to trap certain events (errors) while my program is running. Since I have 50(s) or more connections in 1 time I need to monitor which one is not receiving any data for a couple of mins. What I will do is disconnect that particular connection and reconnect again until everything is ok.
Do you suggest any C# Networking Book becuase i'm planning to drop by the bookstore after office so that I'll have a better idea of this matter (first time on networking thing.)
Thanks and more power to you

Hi everyone.
I have been trying to remove a forms captionbar, but without much success. I have tryed setting the FormBorderStyle to None, but that removes the border as well as the Captionbar, but I want to keep the border as the 3D style. Anyone got any idea how this is done without a lot of coding?

As far as I know, this cannot be done. This "captionbar" and the border are tied together closely in Windows. However, you could draw the border yourself in an painting event (I guess). That case you must access the Windows (XP) theme, get the border, and draw it on the edge of your form. You must, however, somehow change the client area smaller that it is somehow (because the inside edges of the form are painted to be borders now, not client area). And don't forget to do manual painting for systems that doesn't support themes (anything else that Windows XP systems currently). There are a lot of examples how to use themes so you should have no problems if the main idea works...
