design - Coding Database web apps -

-

This is something misleading from me to explain here. When I try to learn a new language, I go with some of these steps:

1) Simple Hello World Program, Math Program, Counter Program

2 ) The interplay between pages is using data (RSS / Atom) from other websites using their APIs.

3) Storing or manipulating the data (mysql / postgresql may call you as database).

Now the third part of handling and manipulating data is a bit confusing to me and it seems that I can not go into the coding. Developers may be, but I want to know how I can imagine this structural way so that the programming database app is easy and I can move without fear of codes and database connections. I mean that even if the language is not used, the steps to make the database web app are quite normal (driver / failing table data / storage etc.) but I can not see it.

For example, how can I create an APL which stores certain information like adobei using JSP / circlet or PHP. What do I need to think before creating a web app? I hope my question is clear.

I've always made data access content very difficult, so I try to make a good one The intangible data access layer that works most for me is a typical database call like this (and I think it's mostly fit for web oriented platforms):

  • Create a database connection and Open
  • Create a database command object
  • What you do to the object (I.e. give this a SQL command, or name a stored procedure to execute)
  • Give the parameter the parameter to work (
  • execute the command
  • Do something with the results
  • At some point,

to create a Data Access object for yourself, Does stuff, do your cleaning (including disposal of items, database transactions) No connection clamp etc.) only to have the required standard database operations should be some public methods, such as "Akgikyutstorprokras" or "Akgikyutsclstetment". In this way, working with a database is boiled to work rather than a big, tedious disturbance.

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...
