If the question doesn't make sense to you, don't provide an answer. The question that was asked was clear, concise and specific. I wish all questions were like this one. Your comment above is valid, however, and I agree with you somewhat, but perhaps he is doing some log file post resolution of the host name and the log file only holds IPs.(for example only). You should have provided this information with your initial answer and people probably wouldn't have voted you down.

Read the comments again. I never said the question doesn't make sense to me. I was rather supporting my answer with the comment.
PogoboyKramer wrote: but perhaps he is doing some log file post resolution of the host name and the log file only holds IPs.(for example only).
You mean you have a log file which contains IP address only and you want to get the host name from IP addresses. How do you think that would be possible. Again, my previous comment answers this question.

I do agree to this and am sorry about it.

Thanks for the response. (I didn't mean to sound priskish, BTW) The IP resolution from log file is something I did a couple years back, but for the life of me, I can't remember how. Maybe I'm just blocking out the bad memories. Have a five for this one.

Are you talking about OCR? or are you talking about extracting text hidden inside image files?

No sir,
I have an Image in which have some information in visible form. And i want to get it as a String Format.
Thanks for reply
If you can think then I Can.

i have a array called rArray and it consist of a list of integers.
how do i compare it to find which one is the smallest or the biggest, assigning smallest to a textbox and biggest to a textbox.
for (int y = 0; y < listBox6.Items.Count; y++)
{
if (rArray[y] < r)
{
}
r is an integer.

This is the umptieth day you are trying to get either the min and max, or the average (not sure which), of a collection of numbers, which is very elementary. Rather than asking basic questions in a random order, I would strongly recommend you buy and study an introductory book on C#; that will teach you the basics of the language, of programming in general, and of Windows programming in particular. In one week's time you could acquire a lot of knowledge, well structured, explained and illustrated, and by doing so raise yourself to a whole different level.
If you don't want to do that, I can only suggest you choose and read some of the excellent articles here on CodeProject (stick to the ones that have a score of at least 4 out of 5), as you are in need of coding examples.

This[^] article discusses sort (using LINQ) on string arrays - but the concepts for integers is fairly similar.
The funniest thing about this particular signature is that by the time you realise it doesn't say anything it's too late to stop reading it.

LINQ also has functions for Max and Min so it can be as simple as...
int[] nums = new int[]{1, 2, 3};
textBoxMax.Text = nums.Max().ToString();
textBoxMin.Text = nums.Min().ToString();

What do you think you should do? This is a fairly basic comparison problem, and you should be able to work it out by just writing out the steps that you would do to perform the same task. Break the problem down into smaller and smaller steps and then you will reach your solution.

Based on your question I would assume this is some kind of homework assignment so you should definitely use my other post suggestion for LINQ and not explain your method in any shape, way or form.... then your lesson is learned 
The reason why this must be a homework assignment is because it is so basic. If you where trying to do this for any other reason (like a career in programming) then you should have more of an interest, which would mean you would have already gone down the route Luc had suggested (which is certainly the way forward) and would not be posting this question ANYWHERE.
The other option is that the potential money for a career in programming is your motivation but unfortunately with great programming career comes great need for ability to think
...maybe I am being too harsh...
int min = nums[0];
int max = nums[0];
foreach(int i in nums){
if(i < min)
min = i;
if(i > max)
max = i;
}
...now the challenge: can you work out how to create nums?

That's easy. You post a follow up question "Urgntz. How to create nums."

Please do NOT ask the same question in more than one place. It doesn't get any better answers, and it annoys people who might have helped you.

Hi,
What would be the fastest way to ping 255 IP addresses?
Are there any example with using multithreading, as I am quite new to threading.
|
|
|
|
|
The multi-threading itself isn't problematic; getting it all done in a reasonable time may be a bit of a problem.
I would use say four to eight identical instances of a class that starts a thread which, in a loop:
- fetches an IP address out of a shared queue;
- calls Network.Ping();
- stuffs the result in another shared queue.
Of course, both queues need their lock.
You should not pre-assign IP addresses to threads, as you can't predict how long a ping operation will take; typically those that succeed run fast, and the failing ones have to wait for their time-out. And adding more threads won't help much as I expect you will end up running in network limitations.
|
|
|
|
|
For my application I can set time-out to less then 250ms, so waiting is not a issue.
When using lock, does this mean the first thread that access "variable" locks the access and
if other threads are trying to access same "variable" wait (like thread.sleep) until it is released?
|
|
|
|
|
1.
250msec * 255 IP adr / 8 threads is still 8 seconds.
2.
yes, said locks would be exclusive, but only while accessing the queue, not while pinging (hence only a small fraction of the time). Like so (in pseudo-code!):
lock(IPadrLock) {
IPadr=IPadrQueue.Dequeue();
}
result=ping(IPadr);
lock(resultLock) {
resultQueue.Enqueue(result);
}

Hey Guys
In our company we switched from Office 2000 to 2010 a couple of days ago. Now we have a very strange Problem. About 6 different applications could create Word reports (data sheets for heat plate exchangers) under Office 2000. Now under 2010 sometimes we can generate the Word report (on the first start after logon), then after the 2nd or 3rd it no longer works, Word opens but the document is blank. The error we see in those applications is "OLE Automation ERROR".
To trace the problem i wrote the following c# application:
_Application wordApplication = new Microsoft.Office.Interop.Word.Application();
var f = new FileInfo(txtPath.Text);
object o_null = Missing.Value;
object o_true = "";
object o_false = "";
object o_filePath = @"" + f.FullName;
Document doc = wordApplication.Documents.Open(ref o_filePath, ref o_null, ref o_null, ref o_null, ref o_null, ref o_null, ref o_null, ref o_null, ref o_null, ref o_null, ref o_null, ref o_null);
String text = doc.Content.Text;
Thats the relevant part of the code, there is just some gui-code more, nothing special. Of course the Microsoft.Office.Interop.Word-Com object is referenced.
On the first launch of this programm, reading the content of a word document works perfectly. The second time i hit the open-document button in this c#-app i get the following error:
System.Runtime.InteropServices.COMException (0x800A1066): Command failed
at Microsoft.Office.Interop.Word.Documents.Open(Object& FileName, Object& ConfirmConversions, Object& ReadOnly, Object& AddToRecentFiles, Object& PasswordDocument, Object& PasswordTemplate, Object& Revert, Object& WritePasswordDocument, Object& WritePasswordTemplate, Object& Format, Object& Encoding, Object& Visible, Object& OpenAndRepair, Object& DocumentDirection, Object& NoEncodingDialog, Object& XMLTransform)
To solve this Problem i tried almost everything:
Different users (all with local admin accounts)
Different computers (newly installed windows xp sp3)
reinstalled Office 2010 /repaired Office 2010
New domain user accounts
Changed the access rights in DCOM-Word-Object to local administrator
The weird thing is, after logging in the first time, generating one word report works, then the second time it sometimes works but on the third or fourth and so on time we get the error above.
I know, this problem lies probably more in the windows system and not the actual c# application (the other applications aren't written in c# but show the same behaviour), but i thought maybe someone of you could have an idea.
I would be really happy if anybody could help me solving this problem. It don't know anything more I could do!
regards from switzerland
