I remember reading a paper a long time ago that talked about object-oriented programming. I believe that this was from the early 1980s or perhaps even before then.
This was at the time when object-oriented programming was still done through pre-processors, and one thing that stuck with me is this: it argued that you could write code in either procedural or object-oriented fashion, and after preprocessing/compiling, you would end up with the exact same machine code.
Does anybody know which paper I'm talking about?
Hello, I have recently started to develop applications for iPhone with MonoTouch and have to store user names and passwords on the phone. I want to use the keychain for this but can't find anything in the MonoTouch documentation about it. Is it possible to use it directly with MonoTouch or will I have to write some C++/C/Objective-C code that uses the keychain and export it to MonoTouch?
Hi there,
I am trying to write a script (preferably in bash) to flatten a java projet directory structure prepending the path to the file. Example:
| src
| org
| apache
| file2.java
| file1.java
would result in:
| src
| org|apache|file2.java
| org|file1.java
The script should be recursive since the directory could have many subfolders.
Hi, i would like to create a Rails controller that download a serie of jpg files from the web and directly write them into database as binary

I have a DataGridView which is filling from Table in SQL Server Database. One of it's columns is "price".
Type of column in DGV is automatically sets as Decimal.
In some cases I need to write in cells of this column text like "none", instead of price.
How can I do it?
DGV.Item("price", 0).Value = "none"
doesn't work, because of decimal type of a cell.

I'll admit I'm a novice programmer and really the only experience I have is in classic ASP. I'm looking for a way to convert this asp code to PHP. For a customer who only has access to a linux box but also as a learning tool for me.
Thanks in advance for the help:

I'm creating a sql based procedure which can
Accept a table
load the values one at a time
send the variables to a remote API
Record the response of the API
Write the response to a table for viewing later
I have successfully implemented 1,2, and 5. I am hoping there may be some way of choosing an address to contact and for SQL to listen too for a response. Please let me know if you have any suggestions!
I'm writing a C++ app.
I have a class variable that more than one thread is writing to.
In C++, anything that can be modified without the compiler "realizing" that it's being changed needs to be marked volatile right? So if my code is multi threaded, and one thread may write to a var while another reads from it, do I need to mark the var volaltile?
[I don't have a race condition since I'm relying on writes to ints being atomic]
Thanks!
We use Captcha control in a registration form that we make full client validation for all fields in JavaScript ( JQuery ) beside server validation ..
I tried a lot of ways but all will write the Captcha value in JavaScript that can be accessed by anyone :(
I search if is there any way that allow me validate Captcha value in client side using JQuery in secure way or it can't be done ?
I need to write a daemon that supposed to have one TCP socket and one named pipe. Usually if I need to implement a multi IO server with "pure" sockets, the select based multi-IO model is always the one I will choose. so does anyone of you have ever used named pipe in select or you
can just tell me it is impossible. thanks in advance.
in a double-submitted cookie csrf prevention scheme, is it necessary for the server to provide the cookie?
it seems i could have javascript on the clients page generate and set a cookie "anti_csrf", then double submit that (once as a cookie, done by the browser, and once in the body of the request).
a foreign domain would not be able to read or write the "anti_csrf" cookie to include it in the body of a request.
is this secure, or am i overlooking something?
Hi,
I am a novice with Websphere MQ and require some novice help.
I am using Websphere MQ Explorer to connect to a queue but do not know how to write the connection string. I have all the details (host, port, channel, queue manager name) but do not know how to put them together correctly as a connection string.
Can any help this novice?
Thanks
Modern keyboards have special multimedia keys, e.g. 'Pause/Play' or 'Open Web Browser'. Is it possible to write a program that "presses" these keys?
I would prefer solution in C, but I would accept a language agnostic solution, too.
Hi,
I have a method which handles a set of records.This method,return true\false after processing.So,if all the records are processed(doing some db updates),will return true.Now,suppose after processing 1 record,some exception is thrown,should I write result=false(at the end of method result is returned) in catch block? And,allow processing of other records to be done?
Hi,
I was wondering if it is possible to make a "link" in usr/bin (i.e.) that leads to a shell-script.
But I want just to write
% shellscript
instead of
% sh shellscript.sh
kinda like an alias.
Is this possible?
In Asp.net (c#),i'm not able to catch exception(FileNotFoundException) properly... i don't know the reason..Actually File s not there..But catch statement fails to catch the exception..
here is the code..

System.Drawing.Image imgg1 = System.Drawing.Image.FromFile(Server.MapPath("").ToString() + "\\images\\img1.jpg");
}
catch (FileNotFoundException)
{
Response.Write("<script>alert('Please Select and upload Student's Photo');</script>");

using the g.drawText function (two calls one for each text) is it possible to write text in two different sizes?
g.drawText("abc",0,0);
//whatever code to change font goes here
g.drawText("def",30,30);
Is there any handy tool that can make updating tables easier? Usually I got an Excel file with the original value in one column and new value in another column. Then I write a formula in Excel to create the 'update' statement. Is there any way to simplify the updating task?
I believe the approach in SQL server 2000 and 2005 would be different, so could we discuss them both? Thanks.
Why do this:
// If parameter cannot be cast to Point return false.
TwoDPoint p = obj as TwoDPoint;
if ((System.Object)p == null)
{
return false;
}
Instead of this:
// If parameter cannot be cast to Point return false.
TwoDPoint p = obj as TwoDPoint;
if (p == null)
{
return false;
}
I don't understand why you'd ever write ((System.Object)p)?

Dan
Ey guys, I have been searching for some sample code on how to store an NSArray in Core Data for awhile now, but haven't had any luck. Would anyone mind pointing me to some tutorial or example, or better yet write a simple sample as an answer to this question? I have read this but it doesn't show an example of how to go about implementing a transformable attribute that is an NSArray. Thanks in advance!
I need to sort a 2 dimensional array of doubles on multiple columns using either C or C++. Could someone point me to the algorithm that I should use or an existing library (perhaps boost?) that has this functionality?
I have a feeling that writing a recursive function may be the way to go but I am too lazy to write out the algorithm or implement it myself if it has been done elsewhere. :-)
Thanks
Is there an easy way to configure in a build process to write in the time stamp of the build to be displayed in the application to have something like "This page was last updated: 06/26/2010"
