  • Editing and iPhone SDK Framework ?

    - by Chris
    I am working with MapKit and want to be able to add a (NSString *)itemTag value to each of my annotations. I have created myAnnotiation.m and myAnnotation.h I tried adding itemTag to the myAnnotation.h/m but when I try to access currentAnnotation.itemTag within my main code, it says "itemID not found in protocols" - so I went to the MapKit.Framework and into MKAnnotation.h. I added (NSString *)itemID, but when I save the .h file in the Framework, it changes the file's icon and doesn't appear to by jiving with everything else. Any help or links to help would be greatly appreciated. I am not even sure if I'm on the right path here, but Googling "modify iphone sdk framework" does not turn up much.

  • Javascript string replace with calculations

    - by Chris
    Is there a way to resolve mathematical expressions in strings in javascript? For example, suppose I want to produce the string "Tom has 2 apples, Lucy has 3 apples. Together they have 5 apples" but I want to be able to substitute in the variables. I can do this with a string replacement: string = "Tom has X apples, Lucy has Y apples. Together they have Z apples"; string2 = string.replace(/X/, '2').replace(/Y/, '3').replace(/Z/, '5'); However, it would be better if, instead of having a variable Z, I could use X+Y. Now, I could also do a string replace for X+Y and replace it with the correct value, but that would become messy when trying to deal with all the possible in-string calculations I might want to do. I suppose I'm looking for a way to achieve this: string = "Something [X], something [Y]. Something [(X+Y^2)/5X]"; And for the [_] parts to be understood as expressions to be resolved before substituting back into the string. Thanks for your help.

  • Disable buttons on post back using jquery in .net app

    - by Chris Lively
    I have a asp.net app that I want to disable the buttons as soon as they are clicked in order to prevent multiple submissions. I'd like to use jquery for this as the site already liberally uses it anyway. What I've tried is: $(document).ready(function () { $("#aspnetForm").submit(function () { $('input[type=submit]', $(this)).attr("disabled", "disabled"); }) }); The above will disable the button, and the page submits, but the asp.net button on click handler is never called. Simply removing the above and the buttons work as normal. Is there a better way?

  • iPhone TabBar selection cancelling

    - by Chris Schnyder
    I am developing an iPhone app that displays several views, all acessed via Tab Bar items. However I need to add an additional item to the Tab Bar that simply launches a URL in Safari. I've accomplished this by adding an empty placeholder view to the TabBar and returning FALSE from shouldSelectViewController when the this view's tabBarItem is clicked on, and launching Safari at the same time. That code is: - (BOOL)tabBarController:(UITabBarController *)tabBarController shouldSelectViewController:(UIViewController *)viewController { if([[viewController tabBarItem] title] == "Website"){ //... launch Safari return FALSE; } else { return TRUE; } } PROBLEM: If the TabBar has too many items, and this "Safari Launch" tab is pushed off to the "More" navigation controller, I lose the capability to intercept the event and prevent the view from loading when clicked. Any suggested tips?

  • reflection paths between points in2d

    - by Chris H
    Just wondering if there was a nice (already implemented/documented) algorithm to do the following Given any shape (without crossing edges) and two points inside that shape, compute all the paths between the two points such that all reflections are perfect reflections. The path lengths should be limited to a certain length otherwise there are infinite solutions. I'm not interested in just shooting out rays to try to guess how close I can get, I'm interested in algorithms that can do it perfectly. Search based, not guess/improvement based.

  • Why can't I make an http request to the ASP.NET development server on localhost?

    - by Chris Farmer
    I have an ASP.NET project (VS2008 on Windows 7 with either webforms, MVC1, or MVC2 -- all the same result for me) which is just the File-New hello world web project. It's using the default ASP.NET development server, and when I start the server with F5, the browser never connects and I get a timeout. I tried to debug this by telnetting to the development server's port while it was running, and I got the same result: C:\Users\farmercs>telnet localhost 54752 Connecting To localhost...Could not open connection to the host, on port 54752: Connect failed I can see in the system tray that the server thinks it's running, and a netstat -s -n command shows that there is indeed an active TCP listener on that port. This worked in the not-too-distant past, and I could work on web projects using the development server. One thing that has changed since then was that I installed the Microsoft Loopback Adapter to accommodate a local development Oracle installation. I'm not sure this is the problem, but it seems a likely culprit. So, what could be blocking me from connecting? And if it's the loopback, then what is a good way for me to retain my ability to connect to my development Oracle server while still being able to use the ASP.NET development server?

    - by Chris
    I using url to request remote urls that sometimes may very slow or just down. In this case, my php scripts still waiting for the response, it makes apache has to many requests stay in memory and then overload. I need a way to stop curl requesting or stop running php script when specified time passed. I'd tried declare(), it makes no sense for curl. Can someone know how to solve it? BTW: what is the effect of CURLOPT_CONNECTTIMEOUT and CURLOPT_TIMEOUT? They don't work like what I think.

  • PHP secure logon script - md5 hash is not matching the hash i wrote to the database in a previous sc

    - by Chris Sobolewski
    I am trying to cobble together a login script in PHP as a learning project. This is the code for my database write when the user registers. Both of these values are written to the database. $this->salt = md5(uniqid()); $this->password = md5($password.$salt); Upon logging in, the following function is fired. For some function challengeLogin($submittedPassword, $publicSalt, $storedPassword){ if(md5($submittedPassword.$publicSalt) == $actualPassword){ return 0; }else{ return 1; }; } Unfortunately, on stepping through my code, the two values have never equaled. Can someone help me understand why?

  • flex/actionscript client entity state refresh on JPA update using Pimento EntityManager

    - by Chris
    My Flex application uses a client-side pimento EntityManager which fetches quite a few objects and associations. It does this by forcing eager fetching of particular association ends in the form of fetch plans. I would like to update the client whenever a change has been made to an entity existing in the EntityManager's cache. Is it possible to update the state of the changed entity ONLY, including updating which entities are associated, without resetting the state of these associated entities? I have setup an EntityListener with a JPA post-update method that notifies clients when a persisted entity has been updated. I want this to trigger a refresh for the modified client-side entity, but calling EntityManager.refresh(entity) resets all lazy associations to proxies. Initializing these proxies resets the associated entities, even if they were loaded previously. I'm looking for an efficient way to keep the client's state in synch with the server's state, at least with respect to the entities that have already been retrieved by the initial load.

  • Uncheck all checkboxes in repeater except checkbox being checked

    - by Chris Laythorpe
    I know my question reads a bit like that 'how much wood can a woodchuck chuck' line, please excuse that... I have a repeater with checkboxes. There are numerous rows in this repeater - I never know how many - I want only one checkbox checked at any time. If the user changes the checked checkbox, any pre-existing checks are unchecked therefore maintaining a single checked checkbox. I am using VB, but comfortable to port any C#. I want to use JQuery. I have been looking on Google, but only ever seem to find ALL checked, ALL unchecked systems. Any suggestions?

  • Inserting nil Values into Sqlite Database?

    - by Chris
    I am working on an iPhone App where I am pulling data from an XML file and inserting it into a sqlite database located in the App. I am able to successfully do this process, but it appears that if I try to sqlite3_bind_text with a NSString that has a value of "nil", the App quickly dies. This is an example of code that fails: (modified for this example) // idvar = 1 // valuevar = nil const char *sqlStatement = "insert into mytable (id, value) VALUES(?, ?)"; sqlite3_stmt *compiledStatement = nil; sqlite3_prepare_v2(database, sqlStatement, -1, &compiledStatement, NULL); sqlite3_bind_int(compiledStatement, 1, [idvar intValue]);; sqlite3_bind_text(compiledStatement, 2, [valuevar UTF8String], -1, SQLITE_TRANSIENT);

  • Get python tarfile to skip files without read permission

    - by chris
    I'm trying to write a function that backs up a directory with files of different permission to an archive on Windows XP. I'm using the tarfile module to tar the directory. Currently as soon as the program encounters a file that does not have read permissions, it stops giving the error: IOError: [Errno 13] Permission denied: 'path to file'. I would like it to instead just skip over the files it cannot read rather than end the tar operation. This is the code I am using now: def compressTar(): """Build and gzip the tar archive.""" folder = 'C:\\Documents and Settings' tar = tarfile.open ("C:\\WINDOWS\\Program\\archive.tar.gz", "w:gz") try: print "Attempting to build a backup archive" tar.add(folder) except: print "Permission denied attempting to create a backup archive" print "Building a limited archive conatining files with read permissions." for root, dirs, files in os.walk(folder): for f in files: tar.add(os.path.join(root, f)) for d in dirs: tar.add(os.path.join(root, d))

  • How to deploy RESTful Web Service onto IIS

    - by Chris Lee
    Hi all, I'm new to .Net and IIS. I've created a simple RESTful Web Service in VS2008 and .net 3.5 framework using WCF. I've tested it well with F5 debugging in VS(seems it is auto deployed on Windows Service). Now I want to deploy it on my IIS server so that I can use it remotely. But I cannot find any guide for this. I manually deployed my service folder just as an ASP.net site. But seems it does not work(keep showing 401 error). Can anyone tell me how to deploy it to IIS? It contains a simple GET method and I hope it can be accessed by anomynous clients (because the host IP is 192.168..). I have a web.config file, a .dll and .pdb under /bin folder, a Global.asax and .svc file for my service. The IIS server is on the same machine. Thanks a million.

  • Is it possible to dynamically add webcontrols via jQuery???

    - by Chris Conway
    Currently I have a webform that has a series of links. What I'd like to be able to do is add a webcontrol's content when one of the links is clicked. Is this kind of thing even possible? If not, what's the best strategy for loading a set of controls (one textbox and one dropdown with values from one link, two textboxes and a checkbox from another link, etc.). I'd need to be able get the values of each of these controls on postback. Ideally, I'd like to be able to add that new content to an acordian control, most likely the jQuery UI acordian. So each clickable link would add new content to an acordian control. What's everybody's thoughts on this?

  • LGPL library with plugins of varied licenses

    - by Chris
    Note: "Plugins" here refers to shared objects that are accessed via dlopen() and friends. I'm writing a library that I'm planning on releasing under the LGPL. Its functionality can be extended (supporting new audio file formats, specifically) through plugins. I'm planning on creating an exception to the LGPL for this library so that plugins can be released under any license. So far so good. I've written a number of plugins already, some of which use LGPL and some of which use GPL libraries. I'm wary of releasing them with the main library, however, due to licensing issues. The LGPL-based ones would generally be fine, but for my "any license" clause. Would distributing these LGPL-based plugins with the library require the consent of the other license holders to create this exception? Along the same lines, would the inclusion of GPL-based plugins with my library force the whole thing to go GPL? I could also release the plugins separately. The advantage, I presume, is that the plugins an d library will now not be distributed together, creating more separation. But this seems to be no different, really, in the end. Boiled down: Can I include, with my LGPL library, plugins of varied licenses? If not, is it really any different releasing them separately? And if so, there's no real need to create an exception for non-LGPL plugins, is there? It's LGPL or nothing. I'd prefer asking a lawyer, of course, but this is just a hobby and I can't afford to hire a lawyer when I don't expect or want monetary compensation. I'm just hoping others have been in similar situations and have insight.

  • Isn't the C++ standard library backward-compatible?

    - by Chris Metzler
    Hi. I'm working on a 64-bit Linux system, trying to build some code that depends on third-party libraries for which I have binaries. During linking, I get a stream of undefined reference errors for one of the libraries, indicating that the linker couldn't resolve references to standard C++ functions/classes, e.g.: librxio.a(EphReader.o): In function `gpstk::EphReader::read_fic_data(std::basic_string<char, std::char_traits<char>, std::allocator<char> > const&)': EphReader.cpp:(.text+0x27c): undefined reference to `std::basic_ostream<char, std::char_traits<char> >& std::__ostream_insert<char, std::char_traits<char> >(std::basic_ostream<char, std::char_traits<char> >&, char const*, long)' EphReader.cpp:(.text+0x4e8): undefined reference to `std::basic_ostream<char, std::char_traits<char> >& std::__ostream_insert<char, std::char_traits<char> >(std::basic_ostream<char, std::char_traits<char> >&, char const*, long)' I'm not really a C++ programmer, but this looks to me like it can't find the standard library. Doing some more research, I got the following when I looked at librxio's dependency for the standard library: $ ldd librxio.so.16.0 ./librxio.so.16.0: /usr/lib64/libstdc++.so.6: version `GLIBCXX_3.4.9' not found (required by ./librxio.so.16.0) libm.so.6 => /lib64/libm.so.6 (0x00002aaaaad45000) libstdc++.so.6 => /usr/lib64/libstdc++.so.6 (0x00002aaaaafc8000) libgcc_s.so.1 => /lib64/libgcc_s.so.1 (0x00002aaaab2c8000) libc.so.6 => /lib64/libc.so.6 (0x00002aaaab4d7000) /lib64/ld-linux-x86-64.so.2 (0x0000555555554000) So I read that as saying that librxio (one of the third-party libraries) requires at least v3.4.9 of the standard library. But the version I have installed is 4.1.2: $ rpm -qa | grep libstdc compat-libstdc++-33-3.2.3-61.x86_64 libstdc++-devel-4.1.2-14.el5.i386 libstdc++-devel-4.1.2-14.el5.x86_64 libstdc++-4.1.2-14.el5.x86_64 libstdc++-4.1.2-14.el5.i386 Shouldn't this work? The shared object major number is 6, same as for v3.4.9. At this level, shouldn't this be backward compatible? It seems like the third-party library is looking for an earlier version of the standard library than what I have installed; but isn't there backward compatibility between versions with the same major number for the shared library? Again, I'm not really a C++ programmer; but I don't see what the problem is. Any advice greatly appreciated. Thanks.

  • XSL Template - reducing replication

    Hey Sorry about the extremely vague question title (any suggestions for improvements welcome) I have an XSL document that, currently, has lots of replication that I want to reduce. Here is the following XML snippet I am working with <Unit Status="alive"> I am currently using the following XSL to show images based on the status of the Unit <xsl:choose> <xsl:when test="@Status = 'alive'"> <img src="/web/resources/graphics/accept.png" /> </xsl:when> <xsl:when test="@Status = 'missingUnit'"> <img src="/web/resources/graphics/error.png" /> </xsl:when> <xsl:when test="@Status = 'missingNode'"> <img src="/web/resources/graphics/exclamation.png" /> </xsl:when> <xsl:when test="@Status = 'unexpectedUnit'"> <img src="/web/resources/graphics/exclamation_blue.png" /> </xsl:when> <xsl:otherwise> <!-- Should never get here --> <img src="/web/resources/graphics/delete.png" /> </xsl:otherwise> </xsl:choose> How do I put this code in a template or stylesheet that will allow me to stop copying / pasting this everywhere.

  • Convert a value based on range

    - by Chris
    I need to convert a number to another value based on a range: ie: 7 = "A" 106 = "I" I have a range like this: from to return-val 1 17 A 17 35 B 35 38 C 38 56 D 56 72 E 72 88 F 88 98 G 98 104 H 104 115 I 115 120 J 120 123 K 123 129 L 129 infinity M The values are fixed and do not change. I was thinking a lookup table would be required, but is there a way it could be done with a function on an analytics function inside of oracle?

  • Lexing partial SQL in C#

    I'd need to parse partial SQL queries (it's for a SQL injection auditing tool). For example '1' AND 1=1-- Should break down into tokens like [0] => [SQL_STRING, '1'] [1] => [SQL_AND] [2] => [SQL_INT, 1] [3] => [SQL_AND] [4] => [SQL_INT, 1] [5] => [SQL_COMMENT] [6] => [SQL_QUERY_END] Are their any at least lexers for SQL that I base mine off of or any good tools like bison for C# (though I'd rather not write my own grammar as I need to support most if not all the grammar of MySQL 5)
