Step 1 - AJAX file uploadAJAX file upload tutorialFirst of all I have to say that to create a pure AJAX file upload system is not possible because of security limitations of JavaScript. All of the Ajax upload systems I know use some third party tool/package or only mimics the AJAX feeling. Even so it makes file upload process a bit nicer. In the next section I will present you a solution which imitates the AJAX process, but uses a normal upload process and iFrames.The concept: Create a simple HTML form for file uploadSet the target to an iFrame which is on the actual page but not visibleC...

Mobile devices of the first generation were not capable of playing any sounds except monophonic ringtones. Today any smartphone platform supports playback, record and to some extent manipulation of digital sound, often up to CD quality.Android is no exception to that. Even older 1.5 devices can do a lot of things with digital audio. However, due to lack of guidance, a developer who is doing his first audio feature might miss some of the available API facilities, or might choose the approach that is not optimal to her use case. This article is supposed to clarify the three major APIs for workin...

Salary is an interesting topic. It's certainly one everyone has an opinion on. It's also a uniquely taboo subject among members of the working public. Since I'm about a month away from being done with University and entering the programmer workforce, I've taken to asking my classmates what type of starting salaries they're getting at their first jobs. The first thing I discovered is that not everybody is very comfortable with this question, and many companies are even less so. Microsoft requests very firmly that recipients of their offers keep their salary offers confidential, for example.This...

memcpy() copies the bytes of data between memory blocks. If the block of memory overlaps, the function might not work properly. Use memmove() to deal with overlapping memory blocks. memmove() is very much like memcpy() but very flexible as it handles overlapping of memory blocks. example : char msg[50] = "abcdefghijklmnopqrstuvwxyz"; char temp[50]; main() { strcpy(temp, msg); printf("Original Msg = %s\n",temp); memcpy(temp+4, temp+16, 10); printf("After memcpy without overlap = %s\n",temp); strcpy(temp , msg); memcpy(temp+6, temp+4, 1...
