I wanna know, wich files i have to upload.
Only the Server.asmx? or Server.dll ?
or Server.asmx and Server.asmx.cs...
and how i use this DLL?
Thanks.

If you want to modify the code, you'll need the Server.asmx.cs, if you just want to reference the dll in a project, then use Server.dll.
Could you be more specific in what you are trying to do? The question is a bit vague.

If you're doing this in VS.NET, just click on the Copy Project button at the top of the Solution Explorer when your project is selected. It asks which you want to copy. Typically in a deployment scenario you just copy files necessary for the application to run. This would be the Server.asmx file and the Server.dll file, which either goes into the bin sub-directory of the application root directory (/, /myapp, whatever) or the Global Assembly Cache (GAC) making it easily accessible for web applications that require it and easy to version (since the GAC stores all versions of an assembly that you install in it, unless of course you were to remove certain versions).

Hi all,
It's my first time to join this site. I having a problem with my program. It deals with huge amout of input. My input size is 15 MB which causes a low in virtual memory...
The program is about to search for a certain pattern in this input text. I'm using the Boyer moore pattern matching algorithm, so i have to load the whole file when started.
Is there a way or an algorithm to divide this file or something?
Thank you all.

If the algorithm requires that the whole file be read in (and frankly, I've never seen such an algorithm but it's true that I'm not familiar with the Boyer-Moore pattern), then you should find a new algorithm. Still, though, it may work if you buffer your file in a particular way.
Buffering the file reads in blocks at a time (commonly 4K, but it can be anything). If the algorithm allows for partial matches, for example, then you know you should keep the previous buffer (or at least part of it), read-in the next buffer, and join the two together to complete the entire match (if it does match).

I want to sign my application and the assemblies that it use, so I know it has not been tampered with when it runs 
Right now there are a binary crack for my application, and I thought I might make it a bit harder for the crackers by signing my assemblies...
So I read in MSDN about signing my assemblies with a strong name, but then I read that all the assemblies that the application calls need to be signed with the same private key...
This is a problem as I'm exposing a plug-in interface where people can make plug-in that the application loads at runtime.
If my program is signed with a strong name, does that mean that the plug-in's need to be signed with the same private key?
If it does it makes the whole strong-name thingy useless for me, as no one can develop plug-in's then...
Anyone out there that know more about this than me who can fill me in on it?

But when a user make a plug-in he makes it in a separate dll, and MSDN states that an assembly with a strong name can only load other assemblies that are signed with the same private key...
Or have I got something wrong...

If I sign an assembly using signcode.exe (and yes, I have a personal certificate  ) is there any way to check if the program is signed when it loads?
That way the program could check that it is signed itself (and not has been changed) and that all the dll's also are signed with my certificate and not tampered with, but ignore the plug-in's...
Is that possible, ot just a bad idea?

Anders,
After doing just a little reading on MSDN, you could invoke the Certificate Verification Tool (Chktrust.exe) with a Process object which should which will extract the X.509 certificate and with the /q flag you could read the result; Succeeded or Failed. There is probably a much better way with Reflection, this would require more research. HTH

Actually, you can use code access security to state that your assembly must be signed with an X.509 certificate or that your application will only load assemblies signed with your certificate. The CLR will make sure that it hasn't been tampered with.

Let say that you only wanted your assembly loaded if it was signed with your X.509 certificate, you'd add the assembly-level attribute:
[assembly: PublisherIdentityPermission(SecurityAction.RequestMinimum,
X509Certificate="hex-encoded value of your certificate")] If you wanted only plugins to be able to call a method if it was signed with the certificate, attribute your method like so:
[PublisherIdentityPermission(SecurityAction.Demand,
X509Certificate="same thing")]
public void MyMethod()
{
}There's a lot of information about code access security in the .NET Framework SDK that will explain more, as well as a pretty decent (but long) article here on CP, Understanding .NET Code Access Security[^].

Of course, just use sn.exe -k KeyFile.snk to create one, and you could even put it into a user or machine store using sn.exe -i KeyFile.snk MyContainerName, using the path (project-relative or absolute) in the AssemblyKeyFileAttribute in the former case, and AssemblyKeyNameAttribute in the latter case.
As far as plugins, they do not need to use the same key unless you use code access security to state that plugins must use the same key (not a good idea). Think about this: in your .config file there's several sections where you can specify a type (like in .NET Remoting config sections or system.net config sections) and they load into your application (though typically in these cases you don't load them directly).
Signing an assembly not only identifies the assembly but provides a level of security as you've discovered, such as determining when the file has been tampered with (the CLR takes care of this) or by using CAS to determine what assemblies to trust.

Hi,
I read some tutorials about scrren capture with C#.
I need a way to draw rectangle selection over whole screen ?
I am able to draw rectangle selection inside my form (application), but I want to draw rectangle selection acros whole screen area (over all active windows, outside my form) to select screen area for capturing ?
How to do rectangle drawing outside app.form ?
Thanks,
|

Look up information on the SystemInformation class.
This class has properties to get the bounds of the entire virtual screen:
public static Rectangle VirtualScreen
and the working area:
public static Rectangle WorkingArea
plus many others
The previous post doesn't account for OS controls that always remain on top like the taskbar.
VirtualScreen should get you what you need;
i.e. the rectangle bounds to draw.

How can you get your application to execute other applications, such as CALC.EXE?
Thanks in advance,
Jon
|
|

The easiest way is probably System.Diagnostic.Process.Start("calc.exe");
However, the Process class has much more functionality that you can use to refine exactly how things should be run and receiving basic information back from the external application.
For more information see MSDN: Process Class[^]

Hello,
How do you set the margin (text) of a column of a ListView. For example:
|Column0 | Column1|
| | |
I am referring simply to the text margin of a column.
Given that you have to derive a class from ListView, what function do you override to set the margin or to draw the text based on a different margin?
Thanks,
Kuphryn

You must override WndProc and handle Windows messages for the header control (which are passed to their parent control's window, which is the List-View common control, which ListView encapsulates). You could handle the NM_CUSTOMDRAW message (sent using a WM_NOTIFY message, actually) and draw your text that way, perhaps extending the ListView control to provide a margin property of some sort (or just hard-code it, depending on what you need the control for).

i made a class that inherits from System.Windows.Forms.Control, IButtonControl
i want to make the button in an irregular shape, so i assigned the Region with a GraphicsPath object
mycontrol.Region = new Region(mygraphicpath)
the problem is that the quality of the button is horrible!not the same as when i draw it without using the Region object

Enable anti-aliasing for line drawing.

i had already tried changing SmoothingModes and CompositingQuality but nothing changes, the problem is there r missing things in the region of my control!
