java - Should I use Vaadin Framework -

-

I tried to play with the bus and I think it is very easy to use. Apart from this, what I like about my structure, it's made up of the top.

Do you think, should I use this framework or is it better to stick with GWT?

As a disclaimer, I work to work for the company.

Wadine uses GWT in a way that has a set of prefocated components in GWT. If you want, you can also create your own components. However, the set of components is quite complete, and can often be customized for their own needs. This means that whenever you change your application, you will need to re-compile your code in JavaScript Do not need to You combine the already available components together.

The framework server is operated, so all logic is handled on the server side. The component has two parts, the client and the server file. The client side is just a dummy "scene" for the component once you interact with it, it sends a message to the server that it or it is pressed / written / etc. The server then decides what needs to be done. This is for increased security, because you can not "hack" logic because only a small API is available in Javascript to send the request. In some cases, the speed of the application may be slightly off the business, but I do not think it is too bad. The worst speed hiccups are usually the DB query round-trips and those that do nothing with the likes of the UI framework. As suggested, because you are away from the server or this time can be a high user hit, as people may be sluggish. Try it in your own environment, to see how well your performance is, close the last application application. There are some ready-made applications that you can just deploy to check it out.

I feel that this option is boiling for the decisions you are making. Webdun is good for web applications because you can create a normal Java application and can easily do dynamic web UI for it. If you are doing something else of a traditional web site, where the user only sees the page - actively communicates with it more often, then there is no better way to go to the daily. Get along with some other free frameworks like Rail or a PHP framework etc. I think you are applying more because you are suggesting that you are using GWT, so it should be good daydream.

Ask more questions, here, at Wadin forums or on IRC Channel # Wadin @ Ferounde and maybe someone why you should not use Vadiin and give more reasons for this.

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...
