  • Static keyboard in uitableview

    - by Martin
    I have a UITableView that holds just two cells with a textfield in each. As my tableview is just for editing the text in these textfields I always want the keyboard to be shown static in the bottom of the screen. So in viewDidLoad I set the first textfield to become first responder. Something I have noticed though is that when I push the UITableViewController into the UINavigationController the keyboard show up a little bit slower so you can see it animate into the screen. It would be much better if it was there already there when the uitableview shows up. I also tried making the textfield first responder before pushing it as recommended but that didn't made the keyboard show at all: MyTableViewController *myTableViewController = [[MyTableViewController alloc] initWithNibName:@"MyTableViewController" bundle:nil]; [myTableViewController.textField becomeFirstResponder]; [self.navigationController pushViewController:myTableViewController animated:YES]; [myTableViewController release]; How can I accomplish this? Thanks!

  • couchdb: one database per account vs all in one database w. a namespace / property

    - by thruflo
    I'm modelling a document generation system in couchdb. It semi-automates the production of proposal and presentation documents from managable document fragments. Much like, say, Basecamp, it breaks down very simply into self-contained data per 'account'. Each account has multiple users, projects, documents, etc. However, nothing should be shared between accounts. I can see two ways of doing this: one couchdb database per account use a namespace / property to identify the account It seems to me that the first approach is conceptually sound and potentially has security and partitioning advantages. However, it seems to me to restrict some cross-database data querying (that I don't have a use case for now but you never know...) and to make updating views potentially require an awful lot of writes. Does anyone experienced with this kind of decision have any advice?

  • How to make my iphone app icon update like the weather app icon?

    - by Toret
    I have an application that I'm currently building that requires me to display a visual update on the application it self. example: The weather app displays 14 degrees celcius and some clouds as its application icon. When the weather changes there is an update to the way the icon looks without having to open the weather app. The applications icon changes to reflect the update in weather. You can then open the weather app to get more information if need be. In my application I need to have an update system like that which shows the user information without opening the application. If they would like more information they can open the application then. I have no idea how to accomplish this task at the moment. I hope someone will be able to help or point me in the right direction. Thank you for your time.

  • How can I strip non-XHTML tags from a string in C#?

    - by No Average Geek
    I need to be able to remove non-XHTML tags from a string containing XHTML that has been stored in a database. The string also contains references for controls (e.g. ) inside the XHTML, but I need clean XHTML with all standard tag contents unchanged. These control tags are varied (they could be any ASP.NET control), so there are too many to go looking for each one and remove them. The way they are closed is also varied, so not all of them have closing tags, some are self closing. How can I go about doing this? I've found some HTML cleaners on-line for including in my project, but they either remove everything or just HTML encode the entire string. Also, I'm dealing with parts of XHTML documents, not entire documents - don't know if that makes a difference. Any help would be appreciated.

  • Clone a 'link' in SWT

    - by Steve
    I have a table of information that includes a username, an ip address, and a timestamp. What I wanted to do was to have the ip address contained within a link object that when the link is clicked it utilizes bgp.he.net to get information about the host/IP address. I have tried creating threads to resolve the IP addresses but it is often a large amount of IP addresses and I read that InetAddress#getByName isn't non-blocking, so I figured having links that go to this site is the next best thing. Question is: Is it possible to have links for each of my IP addresses in the table without creating a new link object for each row? I don't know how bad that would be on memory usage which is why I'm inquiring about cloning an instance of an IP and having the link open bgp.he.net/link.getText()

  • Redirect issues

    - by pinniger
    Whoever wrote the navigation for the site I’m currently working on (classic asp) points the navigation links to a folder, then inside to folder has an index.asp file, so the urls will look something like this www.mysite.com/myfolder/mysubfolder Now, when watch the page load using httpfox, I notice that the first entry is a 302 redirect to the same address with a “/” on the end, so www.mysite.com/myfolder gets redirected to www.mysite.com/myfolder/ (note the / on the end). I’m not to worried that it’s a 302 since its in the admin section of the site, but when I forward the host headers from ISA server, for an https request, its being redirected from https://www.mysite.com/myfolder to http://www.mysite.com:443/myfolder/ and causing all kinds of problems. Anyway, I can’t seem to find any code making this redirect happen, so does IIS 6 do this because the url points to a folder? Or do I need to comb through the code more closely?

  • Fail to resolve a name when calling ConnMgrEstablishConnectionSync()

    - by Rodriguez
    Hi Guys, I'm trying to setup a GPRS connection with ConnMgrEstablishConnectionSync(), so far so good, the connection is established and if I try to connect to an IP address, everything works fine. Alas, when I try to resolve a name: ConnMgrEstablishConnectionSync(); ... gethostbyname("www.google.com"); The result is always an error: 0x00002af9 (host not found). Therefor I'm not able to resolve any name, but if I try to open a browser, the browser is able to resolve everything. Am I doing something wrong? Thanx for your help.

  • Why the data binding in this validation example works in WPF?

    - by MartyIX
    I'm wondering how exactly the XAML sample (MSDN sample) works: <Style x:Key="textBoxInError" TargetType="{x:Type TextBox}"> <Style.Triggers> <Trigger Property="Validation.HasError" Value="true"> <Setter Property="ToolTip" Value="{Binding RelativeSource={x:Static RelativeSource.Self}, Path=(Validation.Errors)[0].ErrorContent}"/> </Trigger> </Style.Triggers> </Style> Questions: (Validation.Errors)[0].ErrorContent - Is this code somehow checked by WPF? Because Validation.Errors may be an empty collection and in ordinary C# code this code may throw an exception. If this data-binding returns null for valid input - the null value is then casted to empty string (in a text control for example)? The index 0 corresponds to the first error message. How can I return more error messages from Validate method? Thank you for responses!

  • CUDA Global Memory, Where is it?

    - by gamerx
    I understand that in CUDA's memory hierachy, we have things like shared memory, texture memory, constant memory, registers and of course the global memory which we allocate using cudaMalloc(). I've been searching through whatever documentations I can find but I have yet to come across any that explicitly explains what is the global memory. I believe that the global memory allocated is on the GDDR of graphics card itself and not the RAM that is shared with the CPU since one of the documentations did state that the pointer cannot be dereferenced by the host side. Am I right?

  • Placing text on UIView in custom location

    - by JAM
    I am trying to calculate a position to place label on the screen. The goal is to place "word" label in lower right corner of the first square block If yellowish square is defined as myView = [[UIView alloc] initWithFrame:CGRectMake(100, 100, 70, 70)]; [self.view addSubview:myView]; [myView setBackgroundColor:[UIColor colorWithHexString:@"FFFFEC"]]; Using it, i'd like to place a label in it's lower right corner l1 = [[UILabel alloc] init]; [l1 setText:@"word"]; [l1 setFrame:CGRectMake(myView.frame.origin.x + myView.frame.size.width, myView.frame.origin.y + myView.frame.size.height, 700, 700)]; [l1 setFont:[UIFont fontWithName:@"Arial" size:10.0]]; [l1 setBackgroundColor:[UIColor colorWithHexString:@"CCFFFEC"]]; [l1 setTextAlignment:UITextAlignmentRight]; [l1 sizeToFit]; This is what happens: The matter here obviously, is in a correct offset. Knowing the font and size of text, how can one correctly calculate it?

  • Check for element equality in an animation function.

    - by Zardoz
    I have the the below code and would expect that in the first pass of the fadeTo function "yes" would be printed as those first two console logs tell me it is the same element. But it doesn't recognize them as equal. What do I miss here? var tds = self.element.find("td:nth-child(" + (columnIndex + 1) + ")"); tds.fadeTo(options.columnFadeOutTime, 0, function() { window.console.log(tds.first()); window.console.log($(this)); if ($(this) == tds.first()) { window.console.log("yes"); } else { window.console.log("no"); } }

  • C++ Beginner - Simple block of code crashing, reason unknown.

    - by Francisco P.
    Hello everyone, Here's a block of code I'm having trouble with. string Game::tradeRandomPieces(Player & player) { string hand = player.getHand(); string piecesRemoved; size_t index; for (size_t numberOfPiecesToTrade = rand() % hand.size() + 1; numberOfPiecesToTrade != 0; --numberOfPiecesToTrade) { index = rand() % hand.size(); piecesRemoved += hand[index]; hand.erase(index,1); } player.removePiecesFromHand(piecesRemoved); player.fillHand(_deck); return piecesRemoved; } I believe the code is pretty self explanatory. fillhand and removepiecesfromhand are working fine, so that's not it. I really can't get what's wrong with this :( Thanks for your time

  • Configure WCF Service Behavior using database

    - by Achhar
    We use database to centralize our configuration. As part of it, I want to store the standard service behaviors configuration like expose service metatdata, service debug, service throttling for a service inside database rather than in web/app.config. I was planing to store the configuration for a behavior in database as XML. For e.g. <serviceDebug includeExceptionDetailsinFault=true / What I am struggling with is once I read this XML from database how do I create ServiceDebugBehavior instance from it and apply it to my service host? I have tried using XML Serializer but didn't had success. Any thoughts on how this could be achieved or any alternate solutions?

  • How to map an property of ClassA to one of SuperclassA?

    - by mystify
    I have a class named SuperclassA, and an class named ClassA. ClassA inherits from SuperclassA. SuperclassA has got an property called something, so a very generic not-much-saying name. In ClassA, I want to have an property which maps to that something of SuperclassA. How could I do that? I want to make absolutely sure that any access to myBetterProperty results in accessing what's behind something. Assigning an value to myBetterProperty should result in assigning one to something, and vice versa. How to? Pointers set up in init? How would that look like? *self.myBetterProperty = &something; ? I'm not sure about that...

  • How to get path to current exe file on Linux?

    - by user1519221
    The code below gives current path to exe file on Linux: #include <iostream> std::string getExePath() { char result[ PATH_MAX ]; ssize_t count = readlink( "/proc/self/exe", result, PATH_MAX ); return std::string( result, (count > 0) ? count : 0 ); } int main() { std::cout << getExePath() << std::endl; return 0; } The problem is that when I run it gives me current path to exe and name of the exe, e.g.: /home/.../Test/main.exe I would like to get only /home/.../Test/ I know that I can parse it, but is there any nicer way to do that?

  • What do C# Table Adapters actually return?

    - by Raven Dreamer
    I'm working on an application that manipulates SQL tables in a windows form application. Up until now, I've only been using the pre-generated Fill queries, and self-made update and delete queries (which return nothing). I am interested in storing the value of a single value from a single column (an 'nchar(15)' name), and though I have easily written the SQL code to return that value to the application, I have no idea what it will be returned as. SELECT [Contact First Name] FROM ContactSkillSet WHERE [Contact ID] = @CurrentID Can the result be stored directly as a string? Do I need to cast it? Invoke a toString method?

  • javascript code to prevent screensaver from starting

    - by gertjan
    Hi all, I am completely new to javascript programming and I have a question that I didn't manage to find an answer for anywhere. I have recently put together a simple slideshow to view the photos remotely that I host on my home computer. This by itself works fine. The problem I run into is that when I'm viewing photos I don't interact with the hardware, which after some time causes the monitor to switch off. This is particularly annoying when watching photos on my mobile phone. My question is: is there a way to prevent this from happening? I am thinking in the direction of faking a mouse or other event every time I refresh the photo, but I have no clue how to do that and if it is possible. Any help is greatly appreciated!

  • XmlResolver Class' GetEntity function

    - by Pok
    I wrote a custom resolver class. It works OK for resolving SYSTEM DTDs, but not for resolving PUBLIC DTDs. When the class has to resolve PUBLIC DTDs instead of the URI of the resource, the function receives the public identifier through the absoluteUri parameter of the GetEntity function. Is there a solution to this. In examples: if I have a DTD declaration like <!DOCTYPE document SYSTEM "document.dtd"> then the custom resolver correctly receives the string "document.dtd" through the absoluteUri parameter of the GetEntity function. if I have a DTD declaration like <!DOCTYPE document PUBLIC "-//Organization//DTD Document 1.0//EN" "http://localhost/document.dtd"> then the custom resolver incorrectly receives the string "-//Organization//DTD Document 1.0//EN" instead of "scheme://host/document.dtd".

  • I18n translation problem

    - by kshchepelin
    I'm about to translate all time zones to Russian and I've done such things: model: # lib/i18n_time_zone.rb class I18nTimeZone < ActiveSupport::TimeZone def self.all super.map { |z| create(z.name, z.utc_offset) } end def to_s translated_name = I18n.t(name, :scope => :timezones, :default => name) "(GMT#{formatted_offset}) #{translated_name}" end end view: <%= time_zone_select :user, :time_zone, nil, :model => I18nTimeZone %> locale file (/config/locales/ru.yml): ru: timezones: "Midway Island": "??????" "Samoa": "?????" .... But there are cases when original string includes some dots (".") Like "St. Petersburg" And I18n.t() tells me that translation is missing. How can I avoid it?

  • Secure way to run other people code (sandbox) on my server?

    - by amikazmi
    I want to make a web service that run other people code locally... Naturally, I want to limit their code access to certain "sandbox" directory, and that they wont be able to connect to other parts of my server (DB, main webserver, etc) Whats the best way to do it? Run VMware/Virtualbox: (+) I guess it's as secure as it gets.. even if someone manage to "hack".. they only hack the guest machine (+) can limit the cpu & memory the process uses (+) easy to setup.. just create the VM (-) harder to "connect" the sandbox directory from the host to the guest (-) wasting extra memory and cpu for managing the VM Run underprivileged user: (+) doesnt waste extra resources (+) sandbox directory is just a plain directory (?) cant limit cpu and memory? (?) dont know if it's secure enough... Any other way? Server running Fedora Core 8, the "other" codes written in Java & C++

  • C# RichTextBox - Partially setting DetectUrls=false

    - by Suds
    Hi, I have this RichTextBox and I have embedded some http links in it. I have set DetectUrls = true, and it displays the links correctly and handles in the event. In the same RichTextBox, I have one more string displayed which looks like this Type http://< Your host name Now, since DetectUrls= true, the portion "http://<" is displayed as a link, while I want this to be text. If I set the DetectUrls=false just before displaying this string, none of the other links are displayed as links. Is there a way to partially set DetectUrls for some strings and not for others? Thanks
