  • Generating scriptaculous ajax.autocompleter on the fly

    - by user279992
    I have a form where the user can dynamically add a new table row with fields. I'm using a simple insertCell/InsertRow with innerHTML to generate the new row. One of those form fields is using scriptaculous' ajax.autocompleter. I have it generating new IDs for all the elements, but it is still not working The new row generated by js has the same source as the initial row of the form that loads at run time, however it does not appear to be calling the autocomplete function. I think my problem lies in that I don't understand when/how the "new Ajax.Autocompleter" is called. Is it not possible to use ajax.autocompleter like this? TIA

  • % operator for time calculation

    - by Chris
    I am trying to display minutes and seconds based on a number of seconds. I have: float seconds = 200; float mins = seconds / 60.0; float sec = mins % 60.0; [timeIndexLabel setText:[NSString stringWithFormat:@"%.2f , %.2f", mins,seconds]]; But I get an error: invalid operands of types 'float' and 'double' to binary 'operator%' And I don't understand why... Can someone throw me a bone!?

  • Why does this code read all ' ' for the anything after the 4th character?

    - by djs22
    #define fileSize 100000 int main(int argc, char *argv[]){ char *name=argv[1]; char ret[fileSize]; FILE *fl = fopen(name, "rb"); fseek(fl, 0, SEEK_END); long len = fileSize; fseek(fl, 0, SEEK_SET); //fread(ret, 1, len, fl); int i; *(ret+fileSize) = '\0'; for (i=0; i<fileSize; i++){ *(ret+i)=fgetc(fl); printf("byte : %s \n", ret); } fclose(fl); } In the above code, when I feed the name of a jpeg file, it reads anything after the 4th character as ' '...any ideas? Thanks!

  • Page content bleeding past footer, dynamic resize?

    - by Spider
    Hey all im learning as i go with editing CSS and PHP and ive manage to put together a layout, looks fine on the main page, but I noticed the content is not stretching properly height wise when i goto click on the 3D gallery. Here is the a link to the page that has the issue: http://www.idreamfx.com/wp/?page_id=36&album=1&gallery=2 as you can see its bleeding past the footer, and the content section is not resizing properly. What steps do i take to allow it to be dynamically resized with the content in it? Doing some searching i came across the code: but i'm not sure if how or rather, where to apply such a code or what it really does?

  • Can I resolve ASP.NET "~" paths without a Control being present?

    - by jdk
    I want to Resolve "~/whatever" from inside non-Page contexts such as Global.asax (HttpApplication), HttpModule, HttpHandler, etc. but can only find the Resolution methods specific to Controls (and Page). I think the app should have enough knowledge to be able to map this outside the Page context. No? Or at least it makes sense to me it should be resolvable in other circumstances, wherever the app root is known. Update: The reason being I'm sticking ~ paths in the web.configuration files.

  • What makes static initialization functions good, bad, or otherwise?

    - by Richard Levasseur
    Suppose you had code like this: _READERS = None _WRITERS = None def Init(num_readers, reader_params, num_writers, writer_params, ...args...): ...logic... _READERS = new ReaderPool(num_readers, reader_params) _WRITERS = new WriterPool(num_writers, writer_params) ...more logic... class Doer: def __init__(...args...): ... def Read(self, ...args...): c = _READERS.get() try: ...work with conn finally: _READERS.put(c) def Writer(...): ...similar to Read()... To me, this is a bad pattern to follow, some cons: Doers can be created without its preconditions being satisfied The code isn't easily testable because ConnPool can't be directly mocked out. Init has to be called right the first time. If its changed so it can be called multiple times, extra logic has to be added to check if variables are already defined, and lots of NULL values have to be passed around to skip re-initializing. In the event of threads, the above becomes more complicated by adding locking Globals aren't being used to communicate state (which isn't strictly bad, but a code smell) On the other hand, some pros: its very convenient to call Init(5, "user/pass", 2, "user/pass") It simple and "clean" Personally, I think the cons outweigh the pros, that is, testability and assured preconditions outweigh simplicity and convenience.

  • fatal: http://myserverip/home/git/example.git/info/refs not found: did you run git update-server-i

    - by bobobobo
    I followed this example to set up a git repository on my server. It worked, and I successfully pushed my code to it. But now, how do I pull or clone? Using the docs, I tried git clone http://REMOTE_SERVER/home/git/example.git .. But for me, I'm getting: fatal: http://myserverip/home/git/example.git/info/refs not found: did you run git update-server-info on the server? I ran git-update-server info, but nothing changed Edit: Ah, hold on. I changed it to git clone ssh://REMOTE_SERVER/home/git/example.git and I'm getting something.. it wants my user/pass, but how do I make the server public then not requiring login?

  • Help me a routing server on Windows XP

    - by Lu Lu
    I am developing client/server applications and need to test them on Internet environment. However, I only have one PC without connecting the public internet, so I have a plan to simulate a virtual internet environment on my PC. I think I will install the virtual machines for my purpose, but I can install only one machine because of my slowly PC. At the moment, my PC has 2 machines: the host machine (use Windows XP) & the virtual machine (use Windows Server 2003 Ent). Each machine will have 2 network adapter (host-only & internal), and in 2 network adapters, the internal adapter is private on each machine, and host-only adapters are connected together. With Windows 2003, routing server is ok, but I wonder on Windows XP, are there any routing server product? Please help me. Thanks.

  • linux dns server

    - by Clear.Cache
    Can someone explain to me how to easily setup a centos 5 (64bit) dns server? I want to use this strictly for dns for my clients who require rdns (ptr) for their domains. I do have IP delegation/authority from the data center and allocated IPs directly from ARIN. I just want to setup a Centos 5 box to use strictly as a dns server, perhaps with redundancy with a secondary, clustered (or not) dns server Server 1 = dns1.mycompany.com Server 2 = dns2.mycompany.com Then, I need simply instructions on how to create rdns records for clients upon request, especially in bulk amounts. Thank you.

  • Is there a way I can use $PATH as defined by my bash profile?

    - by Adam Backstrom
    I spend most of my day ssh'd into servers. I have a series of aliases/functions/scripts that allow me to type p hostname from the terminal and execute GNU screen(1) on the remote side, using the following command: exec ssh hostname -t 'screen -RD'` I've only recently noticed that ssh -t does not get my custom $PATH. Here's some terminal output: adam@workstation:~:0$ sh server 'echo $PATH' /home/adam/bin:/usr/local/bin:/bin:/usr/bin:/opt/git/bin:/opt/git/libexec/git-core adam@workstation:~:0$ ssh server -t 'echo $PATH' /usr/local/bin:/bin:/usr/bin Connection to uranus.plymouth.edu closed. My biggest problem is my custom aliases only try to execute screen, since I can't guarantee an absolute path, and my $PATH is structured so the shell should find the correct one. If my $PATH settings aren't honored, my scripts don't work. Is there a way I can use $PATH as defined by my .bashrc/.bash_profile? I believe PermitUserEnvironment is disabled.

  • Serialize a C# class to xml. Store the XML as a string in SQL Server and then restore the class late

    - by BrianK
    I want to serialize a class to xml and store that in a field in a database. I can serialize with this: StringWriter sw = new StringWriter(); XmlSerializer xmlser = new XmlSerializer(typeof(MyClass)); xmlser.Serialize(sw, myClassVariable); string s = sw.ToString(); sw.Close(); Thats works, but it has the namesapces in it. xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" Will these slow down the deserialization because it will go out to those and verify the XML? I got rid of the namespaces by creating a blank XmlSerializerNamespaces and using that to serialize, but then the xml still had namespaces around integer variables: <anyType xmlns:q1="http://www.w3.org/2001/XMLSchema" d3p1:type="q1:int" xmlns:d3p1="http://www.w3.org/2001/XMLSchema-instance"> 3 </anyType> My question is: Is it necessary to have the namesapces for deserialization and if not, how to get rid of them? How do I tell it fields are ints so it doesnt put in "anytype" Thanks, Brian

  • What do these C operators mean?

    - by Melkhiah66
    I'm reading the book "Programming Challenges: The Programming Contest Training Manual" and are implementing a problem where I do not understand the use of operators c1 and the comparison if (n&1), someone could help me to know they mean? this is the example code #include <stdio.h> #define MAX_N 300 #define MAX_D 150 long cache[MAX_N/2][2]; void make_cache(int n,int d,int mode) { long tmp[MAX_D]; int i,count; for(i=0;i<MAX_D;i++) tmp[i]=0; tmp[0]=1;count=0; while(count<=n) { count++; for(i=(count&1);i<=d;i+=2) { if(i) tmp[i] = tmp[i-1] + tmp[i+1]; else if(!mode) tmp[0]=tmp[1]; else tmp[0]=0; } if((count&1)==(d&1)) cache[count>>1][mode]=tmp[d]; } } int main() { int n,d,i; long sum; while(1) { scanf("%d %d",&n,&d); if(n&1) sum=0; else if(d==1) sum=1; else if(n<(d<<1)) sum=0; else if(n==(d<<1)) sum=1; else { make_cache(n,d,0); make_cache(n,d,1); sum=0; for(i=0;i<=(n>>1);i++) sum+=cache[i][0]*cache[(n>>1)-i][1]; } printf("%ld\n",sum); } return 0; }

However, the axis are messed up! And it seems like I can't see the ups and downs of my line graph. WHy? I don't get what's wrong. I just want to plot the simple stuff on a line chart. Just those data points. Nothing more, nothing less!

  • Unable to load detached NIB in View

    - by Sheehan Alam
    I have two NIB's ParentViewController.xib ChildViewController.xib ParentViewController.xib contains a UIView and a UIViewController. ChildViewController.xib contains a UIButton I want ChildViewController.xib to load in the ParentViewController.xib's UIView I have done the following: Created @property for UIView in ParentViewController Connected File's Owner to UIView in ParentViewController Set UIViewController in ParentViewController's NIB Name property to ChildViewController in Interface Builder Set ChildViewController view property to UIView in ParentViewController I was hoping this would load ChildViewController into my UIView in ParentViewController but no luck. I did get the following warning, which could be the culprit: 'View Controller (Child View)' has both its 'NIB Name' property set and its 'view' outlet connected. This configuration is not supported. I also have added additional code in ParentViewController's viewDidLoad(): - (void)viewDidLoad { [super viewDidLoad]; ChildViewController *childViewController = [[ChildViewController alloc]initWithNibName:@"ChildViewController" bundle:nil]; childViewController.view = self.myView; } Any thoughts on why ChildViewController does not load in the UIView of ParentViewController?

  • "Attach to process" missing from Delphi 7's Run menu

    - by glob
    I have to resurrect an ancient Delphi 7 application, which means I have to use the D7 IDE. Upgrading the project to a more recent version of Delphi unfortunately isn't an option. My new D7 installation's Run menu is missing Attach to Process. Aside from the missing menu item, the debugger works fine (I can debug normal Delphi executables started with Run). I know D7 supported this feature (it's in the help file), so does anyone have any idea what I've missed? The installation is Delphi 7 Enterprise (Version 7.0 Build 4.453). Current Run menuitems: Run Parameters... - Step Over Trace Into Trace to next Source line Run to Cursor Run Until Return Show Execution Point Program Pause Program Reset - Evaluate/Modify Add Watch Add Breakpoint
