How is it "tricky"?
It is said that the most complex structures built by mankind are software systems. This is not generally appreciated because most people cannot see them. Maybe that's a good thing because if we saw them as buildings, we'd deem many of them unsafe.

Here is a method that can work, should in theory also be able to add numbers in string with chars.
<code>
string s = "1234";
int total = 0;
foreach (char c in s)
{
int x;
int.TryParse(c.ToString(), out x);
total += x;
}
</code>
|
|
|
|
|
..and the shortest one:
<br />
string s = "1234";<br />
int total = s.ToCharArray().Sum((x) => int.Parse(x.ToString()));<br />
|
|
|
|
|
Naaah
int total = s.ToCharArray().Sum((x) => ((int)x)-48);
(ok ok , it is more of a hack )
|
|
|
|
|
But you can still leave out the brackets around x :P

You should use the modulus or remainder function and integer division to solve this problem. Using a divisor of 10 you extract one decimal digit at a time from the number. The same technique with a divisor of 16 can be used to extract hexdecimal digits.
Int32 num = 123456789;
Int32 sum = 0;
Int32 temp = num;
while (temp > 0) {
sum += temp % 10;
temp = temp / 10;
}
Console.WriteLine("Sum of all digits in {0} is {1}", num, sum);

Hi! Me and some people have formed a small development team called Condemned Entertainment for making games but we ran into a snag. We have no people who know C# and the engine we are using uses C# wondering if we can get some help if someone can help set us up. my name is Midias on the forums and our leader is Craka_J the forums is: http://www.condemnedentertainment.webs.com/index.html thanks.

How do you get a list of all the computers on the network in C#? What I want is a network machine selection dialog similar to Windows Network Browsing window...

Can any one tell me that how can I get the server name from a lan based network? I mean suppose the C# .exe file runs on a client pc but the server is on one of the network pc. How can I dynamically get the pc name in which the server is installed? I don't want to change my internal code for this. If there is any way that i can read the server as well the pc name on a lan based network?
|

|
|
Two problems... What kind of server?? and if you don't want to change your code, how on earth is your code going to discover the server name??
|
|
|
|
|
Now what I do is read the pc name in which the server is installed on the network from a notepad where I write the pc name. Now is thr any way to read this from network or the pc name from the network dynamically?
|

If the file is sitting in a network share properly setup with appropriate permissions, yes, the PC can read the file. But, the prerequesite here is to understand Windows Networking. If you don't, this is going to be quite a difficult task for you.
Reading a file is easy since it's no different than reading a file from a local drive. The only thing that changes is how you specify the filename. The UNC path would normally be something like:
\\serverName\shareName\folder\fileName

Hello,
I do know how Enums work in C#, although I am not sure if the following is possible to do:
public enum Type<br />
{<br />
PRESSED1 = 0x0100,<br />
PRESSED2 = 0x0104,<br />
RELEASED = 0x0101,<br />
}
Here you see that there are two possible values for a PRESSED-event: 0x0100 and 0x0104. Is it possible to create only 1 PRESSED value that contains both 0x0100 and 0x104?
I suppose it's not possible, mainly since it's an assignment of 1 value.
I get these values with a low level keyboard hook. All keys except the Menu-key (Alt-key) give the code 0x0100 with wParam. Only the Menu-key sends a 0x0104 with wParam and I'm not feeling to check if it is 0x0104 to convert it back to 0x0100.
Thanks in advance!

Well, in binary 0x0100 is: 0000000100000000
and 0x0104 is: 0000000100000100
and 0x0101 is: 0000000100000001
Each bit will probably represent something, the middle bit may mean that the key has been pressed, the first may mean it has been released, and the 3rd might mean that its a special key like Alt or Fn
I'm not sure what you want to do but if you use the enum:
enum Type : int
{
Pressed = 0x0100,
SpecialKey = 0x0004,
Released = 0x0001
}
Then you can AND the values in your enum, with the value that you have, so that you can see what information it contains.
So this statement would return true if the key was being released:
if((myValue & Type.Released) == Type.Released)

Thank you for your response. In order to make it more clear what I exactly want, here is an example in psuedo-code:
<br />
public enum Type<br />
{<br />
PRESSED = 0x0100 AND 0x0104,<br />
RELEASED = 0x0101,<br />
}<br />
PRESSED has both values 0x0100 and 0x0104. So if when I convert an int to Type, it will either be PRESSED, RELEASED or an int.
I hope my point is clear.
Thank you in advance.

Then it shoule be like i said. 0x0100 AND 0x0104 = 0x0100, the thing common in both of them is that one bit in the middle.
So if you set up your enumaration like i demonstrated, then you should be able to see if a button has been pressed/released.
What i'm saying is that 0x0104 is not its own value, its a combination of both 0x0100 and 0x0004 each of which represent 1 bit in the int.
