c++ - What would be the correct design approach? -

-

I have followed the current scenario

I have a validity class in which valid (command *) Function which it validates passed command.

validator {public: validate (command * cmd) {/ / General validation logic}}

I have three sections, WindowsExecute, SolarisExecute and AIXExecute To validate the command before executing Member Function Execution () in SolarisExecute and AIXExecute, create the object directly from the validator and use the valid (comman *) function. 

  class SolarisExecute {public: execute (Command * cmd) {Validator v; Valid Valid = v.validate (CMD); // Based on 'valid' some processing}} class AIXExecute {public: execute (Command * cmd) {validator v; Valid Valid = v.validate (CMD); // Some processing on the basis of 'valid'}}

WindowsExecute is completely different and there is no command in it. Instead it needs to verify some string data. To do this, there is a separate class named as the Windows Videotator, inherited from the vendetta. WindowsExecute :: execute () uses WindowsValidator instead of the verifier.

WindowsValidator: validator {public: valid (const string and xmlData) {// specific validation logic}} class WindowsExecute {public: executed (constring string and data) {WindowsValidate v; Valid Valid = v.validate (data); // Processing on the basis of some 'legitimate'}}

This is the current code

Now I need to do some specific verification of Solaris and therefore Valuerator :: Can not use valid (command *) After the present design, I will need to create a new class named Solaris Validiate and implement my own validation (command *).

I am not comfortable with this approach. I think some issues / comments:

  1. The validator class will be used only by AIXExecute, then why is there a base class, if the remaining argument is not there? Just three sections are SolarisValidator, AIXValidator, WindowsValidator.

  2. Validator :: Valid (command *) unnecessarily inherited in the WindowsValidate class. The signatures of WindowsValidate :: validate and validator :: certified (command *) are different.

  3. I must validate: Valid (command *) Virtual I SolarisValidator :: validate (command *) Introduction This means that I start the upper part of Virtual Points I am, even though I am not using any dynamic polymorphism. So why not go up with # 1 and make three different classes?

What will be the best solution for this scenario, which will be expandable in future also? I am using C ++ for implementation.

Thanks in advance.

It seems that you have the concept of command, which Is it valid or not? Depending on your platform, the command is displayed in a different form.

So I thought: Why "IIDID" has not created an ICMMand interface with a single function, and make your platform-wrapping code the right identical object that for that platform it will make your "execution" call a validator And will therefore make it platform-independent.

Note: This platform-wrapper subsystem Impo is best designed using a factory pattern.

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...
