  • Javascript Split: without losing character

    - by Rohan
    I want to split certain text using JavaSscript. The text looks like: 9:30 pm The user did action A. 10:30 pm Welcome, user John Doe. 11:30 am Messaged user John Doe Now, I want to split the string into events. i.e.: 9:30 pm The user did action A. would be one event. I'm using RegEx for this: var split = journals.split(/\d*\d:/); Thing is, the first two characters are getting lost. The split appears like this: 30 pm The user did action A. How do I split so that the split maintains the first two/three characters (ie 9: or 10:) etc? Thanks!

  • Paypal Payflow pro library

    - by John Stewart
    I already have an express checkout integrated with my Codeigniter application. Now I want to integrate seamless paypal where I collect the CC information and pass it to Paypal (via backend) and once everything is approved, my application shows that to the user. All this with out ever going to Paypal's website. I know that Paypal gives a bunch of sample code but they have so many different products that advertise to do the same thing. Is there any wrapper library in PHP that I can use for handling all this? What sort of design decision is involved in migrating to such system? Would I need SSL certificates for this?

  • Emacs How to redefine Shift-R for expected use

    - by John Bellone
    I've checked my elisp files to make sure that I do not have any bindings that contain Shift+R (and I have not found any). I expect SHIFT+R to print an uppercase character, but instead I get R R undefined inside of the Emacs command line. This is only in C/C++ major modes. Any suggestions? Update: Describing the key shows that it is undefined. How would I define it for the normal, expected use (capitalizing the letter R)?

  • Data model for timesheet to task and/or timesheet to project?

    - by John
    Let's say I want to make a simple project tracking system. A manager can create a project. Then he can create tasks for that project. Team members can record the hours they work for each task or for the project as a whole. Is the following design for the t_timesheet table a good idea? timesheet_id - primary key, autoincrement project_id - not null, foreign key constraint to t_project task_id - nullable, foreign key constraint to t_task user_id - not null, foreign key constraint to t_user hours - decimal Or should I do something like this: timesheet_id - primary key, autoincrement task_id - not null, foreign key constraint to t_task user_id - not null, foreign key constraint to t_user hours - decimal In the second option, I intend to always have a record in t_task labelled "miscellaneous items" with a foreign key to the relevant t_project record. Then I'll be able to track all hours for a project that aren't for any particular task. Are any of the ideas above good? What would be better?

  • Looking for marg_setValue fix in iPhoneOS

    - by John Smith
    I am trying to compile a library originally written for Cocoa. Things are good until it looks for the function marg_setValue(). It says there is a syntax error before char in marg_setValue(argumentList,argumentOffset,char,(char)lua_toboolean(state,luaArgument)); (it's talking about the third argument, not (char) ) I am trying to port LuaObjectiveCBridge to the iPhone. It has two choices, either using Runtime or Foundation. I have discovered there are some problems with foundation so I am trying runtime. But the compiler is not co-operating.

  • How do I get a MessageBox like information window to appear in Java?

    - by John McClane
    I'm learning Java and I have no idea how to do this. I dragged a button on the form in Netbeans, double clicked it and it created this event: @Action public void HelloClickMethod() { JOptionPane.showMessageDialog(this, "The message!", "This is supposed to be the MessageBox title."); } This is the exception the IDE brings up. Cannot find symbol. Symbol: showMessageDialog() Edit 1 Now I changed it to this: @Action public void HelloClickMethod() { JOptionPane.showMessageDialog(this, "The message!", "This is supposed to be the MessageBox title.",JOptionPane.ERROR_MESSAGE); } However the IDE is saying I have an error in the word 'this'. "Cannot find symbol". I don't understand. Why is it so dificult and why are the errors so esoteric. :P

  • iPhone UISlider not visible

    - by John Qualis
    I want to add a UISlider to my app programmatically without using the IB. I am adding a UISlider to my UIViewController using the code below. However I don't see the slider when the view comes up. What am I missing? I am using iPhone SDK 3.1.2. Appreciate any help. @synthesize slider; .... - (void)viewDidLoad { ... ... slider = [[UISlider alloc] initWithFrame: CGRectMake(0, 480 - 80, 300, 20)]; slider.minimumValue = 0.0; slider.maximumValue = 100.0; slider.tag = 0; slider.value = 50; slider.continuous = YES; slider.enabled = YES; [slider addTarget:selfaction:@selector(handleSlider:)forControlEvents:UIControlEventValueChanged]; self.view addSubview:slider]; In the .h file ...

  • Friendfeed schemaless data in MYSQL

    - by John Stewart
    I read an article around schema-less database which sounds cool. (http://bret.appspot.com/entry/how-friendfeed-uses-mysql) But what isn't clear to me is how do they run search queries on this data? Since the data is in JSON format how do we look for it?

  • How to install older Android SDK in Eclipse

    - by John Brunner
    I'm working at the moment at a simple app in eclipse for android. Just receiving and sending data, and using the camera API. I've set the minSDKversion to 8, because I think that has the widest user base. But at the beginning of the project eclipse was asking me which target SDK version I would use, and because I had just one installed (the latest 4.0.3) I've took this. Now I'm asking me if it wouldn't be wiser to install a lower SDK, like Android 2.2, because it would be not that big (compared to the 4.0.3) and my app would not have included all the fancy new features, which are not used in any way?! Or is this complete nonsense I'm talking here, and just should take my 4.0.3 SDK? When not, how can I install a lower version? Help -> SDK Manager is not showing old SDKs...

  • replace values in form.data when form fails validation

    - by John
    Hi I have a form field which requires a json object as its value when it is rendered. When the form is submitted it returns a comma seperated string of ids as its value (not a json string). however if the form does not validate i want to turn this string of ids back into a json string so it will display properly (is uses jquery to render the json object correctly). how would i do this? I was thinking of overwriting the form.clean method but when I tried to change self.data['fieldname'] I got the error 'This QueryDict instance is immutable' and when i tried to change self.cleaned_data['fieldname'] it didn't make a difference to the value of the field. Thanks

  • Model a Zero or One to Many Relationship

    - by John
    How should I model a zero or one to a many relationship in the database? For example, a user record may or may not have a parent. So should my user table have a t_user.parent_id or should I have an associative table called t_user_hierarchy with the columns t_user_hierarchy.parent_id and t_user_hierarchy.user_id?

  • How should important terms be emphasized in documentation?

    - by John Rasch
    Software will often introduce and formalize concepts that may have ambiguous definitions in the real world. For example, in an attendance tracking system, an Occurrence refers to an Excused Absence, an Unexcused Absence, or a Tardy. In technical documentation (both in helper text and in user guides, etc), should these concepts be proper nouns, and as such, should they be capitalized in usage? In other words, which of the following examples is more appropriate: After an Occurrence has been created, it may be converted into an Excused Absence once the Approval Form has been uploaded. or After an occurrence has been created, it may be converted into an excused absence once the approval form has been uploaded.

  • Jquery to hightlight elements in a list

    - by John
    Hi I have a ol list: <ol> <li class="group1">item 1</li> <li class="group1">item 2</li> <li class="group2"> item 3</li> <li class="group3">item 4</li> <li class="group1">item 5</li> <li class="group3"> item 6</li> <ol> and a set of checkboxes which correspond to the class names <input type="checkbox" value="group1" />group 1 <input type="checkbox" value="group2" />group 2 <input type="checkbox" value="group3" />group 3 What I want to happen is that when a user clicks on a checkbox to 'tick' it, any li rows which are not checked are fadedOut (change opacity) and then any rows which have the class which matches the value of the checkbox are highlighter (background colour changed to yellow). So for example if group 3 was clicked, item 4 and item 6 would be highlighted. Then if group 2 was clicked item 3 would be highlighted (item 4 and 6 would remain highlighted). If group 2 was un-ticked, item 3 would become faded out although item 4 and 6 would remain highlighted. The code I have at the moment is: $('input').click(function(){ input = $(this); classVal = "." + input.val(); elements = $(classVal ); if (input.is(':checked')) { elements.css("background-color", "#FFFF00"); } else { elements.css("background-color", ""); } }); This handles the highlighting but does not do the fading of the unchecked elements. I know I can change the opacity using css("opacity", 0.33) or fadeTo("slow", 0.33) but not sure how to handle this in the code and where to put it. If any of my other code can be tidied up also please let me know Thanks

  • Visual C++: breakpoints disabled

    - by John
    I have a 'release with debug info' unmanaged c++ .exe (built with VS2005) deployed onto another PC, the .exe and .pdb are in the same folder. When I try to attach to the process from VS2005, either locally or remotely from my dev PC, all my breakpoints become disabled. I don't get any warning/error popups which makes me think the PDB file is being found, but not seen as 'good'. Is that the right interpretation? I think if it couldn't see the PDB I'd get a "no debug information could be found" popup. Has anyone got any ideas what can be wrong?

  • Polling servers at the same port - Threads and Java

    - by John
    Hi there. I'm currently busy working on an IP ban tool for the early versions of Call of Duty 1. (Apparently such a feature wasn't implemented in these versions). I've finished a single threaded application but it won't perform well enough for multiple servers, which is why I am trying to implement threading. Right now, each server has its own thread. I have a Networking class, which has a method; "GetStatus" -- this method is synchronized. This method uses a DatagramSocket to communicate with the server. Since this method is static and synchronized, I shouldn't get in trouble and receive a whole bunch of "Address already in use" exceptions. However, I have a second method named "SendMessage". This method is supposed to send a message to the server. How can I make sure "SendMessage" cannot be invoked when there's already a thread running in "GetStatus", and the other way around? If I make both synchronized, I will still get in trouble if Thread A is opening a socket on Port 99999 and invoking "SendMessage" while Thread B is opening a socket on the same port and invoking "GetStatus"? (Game servers are usually hosted on the same ports) I guess what I am really after is a way to make an entire class synchronized, so that only one method can be invoked and run at a time by a single thread. Hope that what I am trying to accomplish/avoid is made clear in this text. Any help is greatly appreciated.

  • AssemblyResolve event is not firing during compilation of a dynamic assembly for an aspx page.

    - by John
    This one is really pissing me off. Here goes: My goal is to load assemblies at run-time that contain embedded aspx,ascx etc. What I would also like is to not lock the assembly file on disk so I can update it at run-time without having to restart the application (I know this will leave the previous version(s) loaded). To that end I have written a virtual path provider that does the trick. I have subscribed to the CurrentDomain.AssemblyResolve event so as to redirect the framework to my assemblies. The problem is that the when the framework tries to compile the dynamic assembly for the aspx page I get the following: Compiler Error Message: CS0400: The type or namespace name 'Pages' could not be found in the global namespace (are you missing an assembly reference?) Source Error: public class app_resource_pages__version_1_0_0_0__culture_neutral__publickeytoken_null_default_aspx : global::Pages._Default, System.Web.SessionState.IRequiresSessionState, System.Web.IHttpHandle I noticed that if I load the assembly with Assembly.Load(AssemblyName) or Assembly.LoadFrom(filename) I dont get the above error. If I load it with Assembly.Load(byte[]) (so as to not lock it), the exception is thrown but my AssemblyResolve handler, when called is returning the assembly correctly (it is called once). So I am guessing that it is called once when the framework parses the asp markup but not when it tries to create the dynamic assembly for the aspx page.
