ascii - How to implement C# enum for enumerated char(1) database field? -

-

Ok, so I have a database field that has a small number of potential state codes in type four (1) (for example 'F' = failure, 'U' = unknown, etc.) I have a C # enum class Which corresponds to these states. I can: 

  public enum statuscode: byte {unknown = (byte) 'u', failure = (byte) 'f', // etc}

So far so good but returned from the database in the datatable, the column values ​​are System.Data.SqlTypes.SqlString example is obviously some C # string (or a C # variable) from C # byte (actually from C # variable There are some issues for converting for a UTF-16 codepoint) but in this case I know that the value is constrained for a small set. And the code should be thrown out of the exception if the value outside this set comes.

With it, what's the best way to do this? Is it safe to put on a byte with SqlString? Will convert Would it be better to use just a switch / case to crosswalk them to the values?

I'm not only looking for the "best" way of doing this in terms of getting the right result but also for code clarity. I think I can also use some constants such as 

  public const char UnknownStatus = 'U'; Public const char failure = 'f';

But if possible, I want to use an enum any ideas?

EDIT: To clarify what I want to do with it, I expect these codes to be used repeatedly in my code. For example, I have to work this way I want to be able to: 

  Public Zero DoSomething (StatusCode currentStatus) {if (currentStatus == StatusCode.Failure) {New some expansion (); } Switch (current status) {case StatusCode.Unknown: // break something; }}

And so forth I want to avoid things like: 

  public zero doSomething (four current state) {if (current status == 'F') {// do something}}

From this situation I am using "magic numbers" equal to all the places. In particular, does it make sense to get rid of any other state-flagging system?

Maybe a "static" object? 

  Public Sealed StatusCode {Private variable value; Statsod permission for public static reading = new statuscadet ('U'); Stats failure only for public static reading = new status ('F'); Private status (four V) {value = v; } Public override string ToString () {return value.ToString (); }}

Then, in your code later, you can use it as an enum: StatusCode.Unknown . You can also provide an internal method for the 'pars' of the received value in the StatusCode object.

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...
