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! (=

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.
bon chance

I am trying to solve below problem using regular expression. My input string is something like this
"MTSGNN0002( 1), MTSGNN0028( 645), MTSGNN0050( 10)"
and I want output like this
"MTSGNN0002,MTSGNN0028,MTSGNN0050"
It should delete all charecter which comes between brackets. Kindly help me out in solving this.
Sometimes it's simpler to find what you want than delete what you don't:
s = "MTSGNN0002( 1), MTSGNN0028( 645), MTSGNN0050( 10)"
s.scan(/MT\w+/).join(',') # Change MT to whatever suits your data.
Look at this regexp:
([a-zA-Z0-9]*)\(.*\)
http://rubular.com/r/maZNs0mDkv
From there on it's easy ;-)
Here you go..
\([^\)]*\)|\s
As per your question.. The above replaces the brackets and the text inside and remove the spaces.
Example and Source Demo:
Here i have got one more solution
([(\b]\s.[0-9]*\b\))
http://rubular.com/r/9NyoU3RKUT
replace mathes of this regex \([ \d]+\) with empty string

I am struggling from last two hours to get the all downloadable product links order by title, but not able to achieve because it's giving the wrong order by collection.
Can anyone help me :D
You can get the all downloadable collection by
$products = Mage::getModel('downloadable/link')->getCollection();
but when you try to add the title in this collection using
$products->->addTitleToResult();
then this will automatically add two sorting order one by sort_order ASC and second one by title ASC. So that you will never get the actual sorting result because sort_order always come first. For more details see
Mage_Downloadable_Model_Resource_Link_Collection::addTitleToResult()
So you need to override the above class in your local pool and need to remove
->order('main_table.sort_order ASC' from addTitleToResult()
or create a custom class for the same.

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 want add all status in magento sales order Comment History Box. I have magento1.6.2.0.
I have try to changing in app/code/core/Mage/Sales/etc/config.xml file and add statuses but nothing was changed please help.
No need to change in the code go to Admin Panel->System->Order Statuses you could create states and assign them to whichever status you want them to be.
In magento States are the visible status of the order and Status is the internal status of the order. A bit confusing but if you take a look at the page you should be to get an idea of what this means.
