design - To re-write or not? -

-

This is a strategic question I have a large part of software, web based, which is about 50 to 60 different tasks The software runs approximately 100 MySQL tables, and may be considered as a large module that can target different sets of 3 large audiences. It runs very well.

The software was launched 5 years ago, and has gone through incremental improvements. I designed a lot and wrote the system alone. There are definitely places where the design is bad; And after 5 years, I feel that if I rewrite some parts of it then I can definitely do a better job. But we have never written it from scratch, so some bad designs have been left there. The code works, but design is not at all beautiful at all places.

The system was built on a proprietary software platform; The platform provides strong security (99% of other web platforms, gel saftles, forcible parameter SQL, line based ACL on mySQL data) and performance (the number of resources increases, the number of concurrent hits is not). We do not need the performance benefits when we're out, but it was a good thing to use.

The problem that I am running now is: for the company's good and for myself, I want to move the system to the point where I do not have to maintain it, where I And the person can come and repair and build on it. It has been shown that it will be difficult to hire talent to work on this existing forum. From this perspective, it would be easy to rewrite it using Java (it takes one year) and then the system can be used by others.

We are a small non-computer firm, and it will be difficult to attract top architects to redesign. I am very busy in doing other things to redesign personally. For outsourced contractors, I can get it, but I worry about the quality of the system architecture. The system is also quite complex, so it will be difficult to fix all the requirements (most of the requirements are in my head - although you can make such a case that redesigning and rewriting will force us to do more documentation).

I am tilting towards writing the whole thing again, but serious reservations any thoughts?

If you do not have then you should not overwrite a system to try the existing system and again : It will take longer to try. There are many examples of software companies who try and do so and fail. (See Netscape)

c# - ListView onScroll event -

-
I am programming a simple C # application, and I need a Scallow event on the list view. So I inherited the original ListView class created in ListviewEx witch. I found out how to locate the scroll message from WinAPI and I modified the WndProc method. Now I have this WndProc: protected override zero WndProc (Ref message message) {base.WndProc (Ref I); If (m.msg == WM_VSCROLL) {onScroll (This, New EventArgs ()); }} But the problem is, I do not know how to know about scrolling information. This data should be in wParam, but there is a LOWORD macro ++ like in C in C # and I switch to find the criteria like SB_ below, SB_ENDSCROLL, SB_PAGEUP etc. there any way Need to change the LOWORD macro from C #? Or any other way to find the necessary parameters about scrolling? You can define the WParam constants as the following: Private const int WM_HSCROLL = 0x114; Private Constant WM_VSCROLL = 0x115; Private contact int SBHOZZ = 0; Private Consultant SB_VERT = 1; Private Con...

PHP - get image from byte array -

-
I am trying to create a back-end for my mobile application. I am sending the content of an image in the body of the HTTP request (output stream) as a byte array, I want to read this stream of bytes in PHP scripts and take back an image. Can anyone tell me how can I do this? Thank you. You can obtain the request body $ body = Reading from file_get_contents ('php: // input'); What you do with that data Depending on you, you can write the data in a file as you mentioned that this is image data, you can drop the data into the object can do. Another option is to use and load the image.

Linux Terminal Problem with Non-Canonical Terminal I/O app -

-
I have a small app written in C to run on Linux. Part of the app accepts user-input from keyboard , And it uses non-canonical terminal mode so that it can respond to each keystroke. The section of the code that accepts input is a simple task that is called repeatedly in the loop: char get_input () {char C = 0; Int res = reading (input_tamille, & amp; c, 1); If (RSS == 0) 0 returns; If (res == -1) {/ * snip error handling * /} return c; } It reads a letter from the terminal if there is no input within a given time limit, (c_cc [VTIME] value in the vocabulary structure), read () 0 And get_input () is called again It all works very well, I have recently discovered that if you run this app in a terminal window, and then the app Close the terminal window without ending, the app will not exit Received, but CPU intensive launches into an infinite loop, where the read () returns 0 without waiting continued. So how can I get out of the apple if it runs from the terminal win...
