this might seem a very very foolish question ..but the fact is i am totally new to VB and got least knowledge of it. i have to make some changes in a code . i need to know that is LogMessage an in-built or predefined function(or method or class) like print f in C. if so.. then why is it inherently been defined in a code ....like this:
Sub LogMessage(From As String, Msg As String)
txtLog.Text = txtLog.Text & From & ": " & Msg & CRLF
txtLog.SelectionStart = txtLog.Text.Length
End Sub
it is not a pre-defined function/method.
when you see it defined with only a 'Sub' or 'Function' word in front of it it means that is is user-written code.

I have a string like this /4/LM2301_800.mp4.
I would like to use a regex to strip the /4/ and the _800 from the file name.
I am currently trying to use the strip command. Can anyone point me in the right direction?
Your file could be deeply nested inside a directory structure:
path = "/4/LM2301_800.mp4"
path.sub(/^(\/.)*\/(.*)_\d+\.mp4/, $2)
=> "LM2301" # you already know these are mp4 files, so you could add the suffix
Or:
path = "/4/LM2301_800.mp4"
path.sub(/^(\/.)*\/(.*)_\d+\.(.*)/, $2+'.'+$3)
=> "LM2301.mp4"
" /4/LM2301_800.mp4".scan(/.*\/(.*?)_\d*(.*)/).join
=> "LM2301.mp4"

I am making a application(desktop app), and need to fetch ids from DB and pass these ids to another desktop application.
How to achieve this?
Your question is your answer. You can use command line argument passing in windows application. As to how to do this is written below.
You can Create a process and call the application to start and pass those arguments:
Process pro=new Process();
pro.StartInfo.FileName = #"ApplicationName.exe";
pro.StartInfo.Arguments = arg1 + " " + arg2;
pro.Start();
pro.WaitForExit();
in the second application get these values by following the below code:
var arguments = Environment.GetCommandLineArgs();
if (arguments.Length > 1)
{
productIdFirst = Convert.ToInt32(arguments[1]);
productIdSecond = Convert.ToInt32(arguments[2]);
}
If I understand you correctly then you're talking about a website and you could pass it a query string. If that is the case then you should check out http://msdn.microsoft.com/en-us/library/system.web.httprequest.querystring.aspx :)
I agree to Martim, that it is no clear if your tags "Windows" not perhaps mean "Website". But if you really mean "Windows" like you've tagged, you can use COM as Middleware. A german article already has great explanation with code samples. Languages can be translated.

I am new to CI.
Now i am try to develop the comment system with reply option.
So far i have developed the insert comment and reply comment.
But i don't know how to fetch reply comments under the main comment.
Please help me.
Thanks to all
Use a recursive function! For that you will need to do something like this:
Get the first comment.
Call the recursive function. The ID of the comment must be passed as an argument.
The function must get the comments & call itself in order to get all the comments.
A pseudo-code of this schema will be:
myComment = getComment();
recursiveComments(myComment);
function recursiveComments(currentComment){
print(currentComment);
replies = getReplies(currentComment['idComment']);
foreach(replies as reply){
recursiveComments(reply);
}
}
In the pseudo-code, I'm assuming that you get a row_array with the getComment() function & that this comment is the "head" of all the comments, like the initial post.
After that, I call the recursive function which gets all the replies & sub-replies for each comment. Note the I fetch a single reply in each call to the function.
Hope this gives you an idea! (=

I'm thinking about duplicating the system\english\form_validation_lang.php file or folder, but I don't know how could I work that out.
For new languages, you should just create a new form_validation_lang.php file inside each language folder, like:
application/language/portugues/form_validation_lang.php
application/language/espanol/form_validation_lang.php
application/language/french/form_validation_lang.php
Then, you just have to set the appropriate language and Codeigniter will fetch the translations according to the language set.
More information can be found in the Codeigniter User Guide

I'm stuck here:
puts "#{percent_finished.round}% uploading complete" ? if/unless ...
If percent_finished is part of an ActiveRecord model, you can actually just make a call to percent_finished_changed?.
For example:
puts "#{percent_finished.round}% uploading complete" if percent_finished_changed?
Here's some documentation:
http://ar.rubyonrails.org/classes/ActiveRecord/Dirty.html
Is this a command line tool?
last_percent = nil
upload_loop do
# ...
percent_rounded = percent_finished.round
puts "#{percent_rounded}% uploading complete" if percent_rounded != last_percent
last_percent = percent_rounded
end
