• How to generate a cell click event in Excel 2007 VSTO with VB?

  - by Kevin Boyd

  Well I have browsed through Application events in Excel 2007 however I can't find any event generated on a cell click. I can't use a double click event at the moment due to application constraints. Is there a way I can create a custom click event and attach it to a sheet for generating a cell click event.

• How to store data which contains quotes in MySQL

  - by Nitz

  In one of my forms I use the rich text editor from Yahoo!. Now i want to store the data from that textarea in a MySQL database. The user can enter anything in that textarea, e.g. many double or single quotes. How can I store that data? Normally we store by adding that data in one variable and then put that in sql, but the quotes cause problems.

• What is the origin / meaning of these variable naming conventions?

  - by Andrew Hubbs

  What is the general meaning and where did it start to have variables with leading or trailing underscores? ex: _varName and varName_ I have always thought a leading underscore indicated the variable was a pointer but I don't know where I got this idea. Recently I have seen these naming conventions used in Java which makes that reasoning completely wrong.

• Web UI for inputting a function from the reals to the reals, such as a probability distribution.

  - by dreeves

  I would like a web interface for a user to describe a one-dimensional real-valued function. I'm imagining the user being presented with a blank pair of axes and they can click anywhere to create points that are thick and draggable. Double-clicking a point, let's say, makes it disappear. The actual function should be shown in real time as an interpolation of the user-supplied points. Here's what this looks like implemented in Mathematica (though of course I'm looking for something in javascript):

• Linux signals with extra information parameter

  - by Tester

  I was to have some extra information in the callback to sa_sigaction handler, it does not seems possible. So I was wondering if you could suggest me alternatives. Basic requirements: Function A raises an signal/event with a pointer to a struct Handler function tackles the event. The handler function would only be called on an event and a loop to wait for the event, as in select() , is undesirable. TIA

• [C++ / NCURSES] Can't convert from 'int' to 'int *'

  - by flarn2006

  So I have these lines of code: int maxY, maxX; getmaxyx(stdscr, &maxY, &maxX); It gives me the following error: error C2440: '=' : cannot convert from 'int' to 'int *' Conversion from integral type to pointer type requires reinterpret_cast, C-style cast or function-style cast twice for each time I use it. I'm not even using the = operator! The curses.h file is included. What am I doing wrong?

• LInux C++: how do profile time wasted due to cache misses?

  - by anon

  I know that I can use gprof to benchmark my code. However, I have this problem -- I have a smart pointer that has an extra level of indirection (think of it as a proxy object). As a result, I have this extra layer that effects pretty much all functions, and screws with caching. Is there a way to measure the time my CPU wastes due to cache misses? Thanks!

• C++ variable alias - what's that exactly, and why is it better to turn if off?

  - by Poni

  I've read the essay Surviving the Release Version. Under the "Aliasing bugs" clause it says: You can get tighter code if you tell the compiler that it can assume no aliasing.... I've also read Aliasing (computing). What exactly is a variable alias? I understand it means using a pointer to a variable is an alias, but, how/why does it affect badly, or in other words - why telling the compiler that it can assume no aliasing would get me a "tighter code"

• What do people find difficult about C pointers?

  - by Paul

  From the number of questions posted here, it's clear that people have some pretty fundemental issues when getting their heads around pointers and pointer arithmetic. I'm curious to know why. They've never really caused me major problems (although I first learned about them back in the Neolithic). In order to write better answers to these questions, I'd like to know what people find difficult. So, if you're struggling with pointers, or you recently were but suddenly "got it", what were the aspects of pointers that caused you problems?

• Does using magic_quotes() affect the use of mysql_real_escape_string()

  - by hairdresser-101

  If I have magic_quotes switched on and I use mysql_real_escape_string, will the tring be double escaped? Will it cause problems? I assume so based on the get_magic_quotes() function but just seeking confirmation. (PS it's easier to ask this question than test it in my office with all the security we have in place - It takes me 10-15 to configure everything to get a useable envirnment)

• Anyone know about building a custom 'relevance' search of, say, a database?

  - by Daniel

  We need to be able to do a 'sort by relevance' search of a database for our application, but Googling 'sort by relevance custom search' doesn't do much good other than seeing Google Custom Search a 1000 times. It's a Cocoa CoreData database (double alliteration) if that matters. Thanks!
