design patterns - Database Abstraction - what are the options? -

-

How can I restrict my database to my application so that it is unaware of the database type? I have to design a .NET 3.5 WPF application, which is to support SQL Server or Visual FoxPro as a data repository.

My design goals are:

  1. Type the data invisible data repository
  2. switch between SQL and FoxPro while writing code in the Data Access layer Do not make as quick and painless as possible to do
  3. Allow the use of both ANSI SQL and stored procedures DL
  4. To learn for other developers joining the project At least the state Ahia

It is using will have a WPF application, perhaps Sisela.

I have thought of using any type of ORM but there is no experience with such technology. Many ORM database types are agnostic, although FoxPro requirement can restrict your choises or you Needs to be typed. Own provider or adapter

If you want your app to be able to work with multiple database types, then through the configuration, you should be careful that your schema is consistent in every database and you depend on those features Which are not implemented in any of the databases or ORMs you have selected.

The ORM I am most familiar with LLBL Gene Pro supports 5 or 6 back-end databases, but FoxPro is not officially supported by a customer contributing to the FoxPro adapter at one point. I do not know that it has been maintained.

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...
