iphone - AutoCompletion on UISearchBar -

-

I am developing applcation with UISearchBar & amp; Tableview Enter event on UISearchBar text I am reading four. & Amp; For the recorded text I am getting results from the database but the problem is that it is a blocked call. So I waited until the result is returned, but then I press the next four presses. I have to ask the database to enter for each character, I have query to enter the whole text from the database. I want to implement auto-compositing like Google search bar in the Google search bar, the user has to wait to get the list of voiced characters Iwant that I am using iPhoneSDK 3.0 to be implemented in my applcation The same thing is going on when I'm pressing backspace. But the problem is that this application crashes on iPhone Simulatior if I constantly press backspace.

Can someone signal me ???

You can always apply your text lookup to a different thread - this is likely to present suggestions often. Can not do it, but it does not have at least blocks

If you do this, make sure to "remember" the text, which is based on lookup - then, if the text in the UISearchBar does not match now, then remove the result - it will no longer apply .

Example:

The user has typed "bri" Tour Lookup determines that potential suggestions are "bridal", "bridge", "bride" and "brigade" In the time of your lookup, the user has added 'D', then you do not want to make any other suggestion of "Brigand". You do not necessarily have to throw out the entire list, but at least you want to delete the items that are now working Do not do it.

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...

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.

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...
