I am working on my minor project. I have to create an image editor in C. For that I want to handle mouse. As I know there are two approaches to handle mouse viz REQUEST MODE and EVENT MODE.
Over the past few days I have learnt Request mode but I'm having difficulty in performing a couple of things with request mode, so I decided to learn second approach i e Event mode. But unfortunately I can't find proper resources. It would be very nice of you if you can get me some examples and explanation of event mode approach.
look at this site
http://www3.telus.net/alexander_russell/course/introduction.htm
its a dos game programming site
there is a mouse section at chapter 4

I want to implement some on-demand warning messages to my login page, like when you type your username site immidiately warn users "checking.. this username is already using". How can i do this with Angular.js ?
The ng-change directive on an input will let you know when the model is changing.
In the handler function you call the server's api, through the $http service it'll return wether the username is in use or not. And you just show it with some magic binding.
Good developing, if you have further question regarding this application. SHOW US CODE!
UI Bootstrap's typeahead directive may give you a jumpstart.

I'm having a strange problem in a project where I'm using the singularitygs for the first time: when resizing the viewport I get an horizontal scrollbar bellow the 838+/- px... and I'm having a really hard time figuring it out the reason and if it's related with singularity.
The project development website is available at:

I would really appreciate a hand from anyone more experienced.
Thanks for your time.
Best,

This isn’t a singularity issue but something is overflowing your <section> tags. Just style your <section> tags with overflow:hidden. Looks like you are applying your styles to #about, #process, #services, #clients, #contacts so just adding overflow:hidden there works just fine.
Also, Nice to see you using Omnes ;)

Can someone guide me on how to implement my own FIFO application to use is in IPC, I know that I can do this with SHM, socket or using any other sys-v or posix ipc.
The reason I'm looking for this is because I wanna build this fifo with my own specification that will suite my applications with the locking inside this application, so that any application can only call enqueue or dequeue, just like with fifo the kernel will make sure that it's atomic as long as you are writing less than the pipe_buff. I know how to build circular buffer queue but I'm not sure how will I call it from another application, do I need to build an API for it ? or is it something else?
the system is Linux and the language is c.
I would strongly recommend using POSIX MQ library. They are thread safe and I believe may be persistent. I've used it with a lot of success and it allowed me to focus on solving the problem at hand instead of rolling my own.

I have two pieces of source code for two dll files. They both work individually, but i need them to be put into one dll file.
The first source is here: http://pastebin.com/vqtNLca8
The second source is here: http://pastebin.com/yvFPEMkf
How can i make this one dll file?
Pass them both to LINK.EXE when you build the DLL.
You'll also want to disable one of the DllMain definitions, to avoid a symbol multiply defined error.

I have seen that related question but it didn't helped. I have a simple silverlight mvvm application for which I have created custom views and viewmodels and I have set the main view as rootlayout. Compiles succesfully, but when I hit run, the app hangs at 100%. I have placed breakpoints all over the app (in the views and in the app.cs) but it never reaches them. I'ved also replaced the mainview with a simple page with only a simple button on it (and set it as rootlayout), but still it hangs at 100% (I'ved thought that my view caused the problem, but it doesn't work on simple pages as well).
Is there any way to view the exceptions? Or something that I am missing...??
Silverlight version 3.
Thanks in advance
