AutoCompletion on UISearchBar - iphone

I am developing applcation with UISearchBar & TableView. On UISearchBar's text enter event I am reading char. & for entered text I am geeting results from database. But problem is that it is kind of blocking call. so I have wait till result gets back but again I pressess next char. I have to query from database. For each chars enter, I have query with entire text enterd from database. I want to implement AutoCompeltion like google search bar. As In google search bar, to get list for entred chars user has to wait.
Iwant that to be implemented in my applcation. I am using iPhoneSDK 3.0.
Same thing is running while I am pressing BackSpace. but the problem is that on iPhone Simulatior it application crashes if I press BackSpace continuously.
Can anybody give me hint ???

You could always implement your text lookup on a separate thread -- it might not offer suggestions as often, but it at least wouldn't block.
If you do this, make sure to "remember" the text the lookup is based on -- then, if the text in the UISearchBar no longer matches it, throw out the results you had -- the will no longer apply.
Example:
The user has typed "bri". Tour lookup determines that possible suggestions are "bridle", "bridge", "bride" and "brigand". If by the time your lookup returns the user has added a 'd', you don't want to suggest "brigand" any more. You don't necessarily have to throw out the whole list, but you want to at least remove the items that no longer work.

Powershell Selenium: Unable to Locate Element on Amazon

I'm trying to create a Selenium script in Powershell that automatically buys something that I tell it to. I've gotten it past finding the item, and clicking the Buy Now button, but then this window pops up and I've tried what seems like 3000 different ways of failing to click the Place your order button. Web code to the right. Appears to be the "turbo-checkout-pyo-button", but finding it by ID, XPath, CSSselector, etc have all failed for me. It's not a wait issue. I've even thrown in an explicit (and overly long) 5 second delay to be sure this field is present and "should" be clickable. Any ideas?
I've tried all of these. They're all followed by $placeYourOrderBtn.click() (and have all failed):
$placeYourOrderBtn = $ChromeDriver.FindElementByXpath("//*[#id='turbo-checkout-pyo-button']")
$placeYourOrderBtn = $ChromeDriver.FindElementByXPath("//*[#id='turbo-checkout-place-order-button']")
$placeYourOrderBtn = $ChromeDriver.FindElementByXPath("//span[text() = Place your order]")
$placeYourOrderBtn = $ChromeDriver.FindElementById("turbo-checkout-place-order-button-announce")
$placeYourOrderBtn = $ChromeDriver.FindElementById("turbo-checkout-pyo-button")
$placeYourOrderBtn = $ChromeDriver.FindElementByCssSelector("#turbo-checkout-pyo-button")
I did this for a windows that sends email. You have to click the button to open the new window, then use "SwitchTo()" to change to the new window.
[void]$Webdriver.SwitchTo().Window($WebDriver.WindowHandles[1])
You may have to read the window handles attribute and query each one to determine which one you need to open.

MaxMSP/Arcade Button Responding Incorrectly with HI Objject

I'm linking an arcade button connected to a USB encoder with a Max patch. The button is behaving strangely. Here's what happens:
I have the button mapped to the a key. When Max is open, this functionality breaks. Even outside of Max. Even once I close Max, I need to remap the key. I'm not using MAME or anything like that; just JoytoKey for the mapping.
This issue is negated partially through use of the HIobject. Max recognizes the button and I can use it, however it's not functioning as an on/off. Rather a bang is sent on button press and release. How do I make the button work normally (send a single bang on press, and none on release)?
Here's my patch, if it helps. I don't know how useful it is without my video files:

It's hard to give an exact answer without knowing what your USB device outputs, however in your patch whatever exits the [hi] object goes into the [live.text] button, which is set to Button mode, always converting it to a bang.
In the patch below I set the [live.text] button to Toggle mode. I also took the liberty of cleaning some other things up.
The next thing though is that you will need to find out what part of the output of the hi object is the information you are looking for. You can do that with a [print] object. Then you can select that number with an [unpack] and select the 1's and use that to trigger [random] (see the patch below).

Configure dwm (Linux) to peek when MODKEY is held

I just installed dwm on Arch and am loving it. However, I found that I have no use for the status bar except when I'm switching tags, so I thought a useful feature would be to only display it while MODKEY is pressed.
I know that MODKEY+b toggles the bar, but I'd like to be able to peek at it while MODKEY's being held down. I'd also prefer that this doesn't consume the event, so I'll still be able to chain additional keys onto the sequence.
The only thing I found online about this was a post from Lokichaos (https://warosu.org/g/thread/24122078):
I split the difference with "peek" behavior. When I hold down Mod4 (my main dwm modkey) it shows the bar (but does not reserve space for it). The bar also auto-shows when there is an urgent client waiting (so I can see the highlighted tag). [...]
Is there any way I could implement this with my config.h file, or would I need to get into the nitty-gritty dwm.c? Any ideas as to how this could be done in an organized fashion so that I could bind other actions to key presses and releases?
Thanks for your help!
--EDIT--
This patch allows you to listen to release events, (they even show you how to toggle the bar with pressing/releasing MODKEY+b), but I'm only able to listen to presses and releases on non-mod keys. Again, my goal is to have the bar display when I press MODKEY, and disappear again when I release it.
Here are the three things I've tried in config.h:
type modifier key function argument
{ KeyRelease,MODKEY, 0, togglebar, {0} },
{ KeyRelease,MODKEY, NULL, togglebar, {0} },
{ KeyRelease,MODKEY, XK_Super_L, togglebar, {0} },
...to no avail.
You may try holdbar patch to serve your purpose. I am using this and it is working seamlessly without any errors.
Note that after using this, togglebar will not work any more and bar will be always hidden. Also you cannot map HOLDKEY to simply MODKEY as it takes keysym bindings. You can get them by running xev and pressing the required key. It's keysym value in hexadecimal will be displayed. I use the Super (Windows) key and it's keysym value is 0xffeb. I have applied the same patch. If you want to see, you can view it on Github.

Real Time Search in UITableView

I have implemented a UISearchBar for finding an element in UITableView. Everything seems to work fine, and now I am at the part where I need to actually perform real-time search for every key pressed in the textField, and narrow down the search with every button press.
So before I start coding, I wanted to know if there is any inbuilt library function that could help me with live search ? (string comparison) or anything ?
Your answer could save me some time.
Thanks.
It so happens that there is in fact an inbuilt function that helps with RealTime Search. Phew !
NSRange match = [userNameString rangeOfString:searchText options:NSCaseInsensitiveSearch];
// match.location will provide the exact location of a match of searchText with a String
// match.length will provide the length of match

Words Per Minute Iphone SDK

I need to calculate words per minute while typing in textfield. It is typing speed calculator and it provides user text need to be typed in the lable above textfield. Please give me some idea how to get started and what events to use.
Thanks you.
UITextField lets you set a delegate implementing UITextFieldDelegate. That object will be sent textField:shouldChangeCharactersInRange:replacementString: for each edit the user does (for example entering a char).
In there you can implement your logic - saving the timestamp of the first entry, comparing each entry against the correct string, and then, when the entire string has been entered by the user, dividing the number of words with the spent time.
