  • JQuery delegate what may cause it to not function

    - by Jafin
    I have a webpage using jquery 1.42 The following 2 segments of code live in my page. $('body').delegate('h2', 'click', function() { $(this).after("<p>delegate paragraph!<\/p>"); }); $('body h2').live('click', function() { $(this).after("<p>live paragraph!<\/p>"); }); The live method always works, yet the delegate doesn't fire at all. If I create a trivial page with simple html <body><h2>blah</h2></body> both approaches work. So I'm assuming there is something else going on in my page. With firebug I am seeing no javascript errors, no html errors. and breakpoints on the delegate method definately do not get hit. What else might be the cause of delegate not triggering?

  • Dynamic Operator Overloading on dict classes in Python

    - by Ishpeck
    I have a class that dynamically overloads basic arithmetic operators like so... import operator class IshyNum: def __init__(self, n): self.num=n self.buildArith() def arithmetic(self, other, o): return o(self.num, other) def buildArith(self): map(lambda o: setattr(self, "__%s__"%o,lambda f: self.arithmetic(f, getattr(operator, o))), ["add", "sub", "mul", "div"]) if __name__=="__main__": number=IshyNum(5) print number+5 print number/2 print number*3 print number-3 But if I change the class to inherit from the dictionary (class IshyNum(dict):) it doesn't work. I need to explicitly def __add__(self, other) or whatever in order for this to work. Why?

  • AutoIt simulate new script line

    - by Renato Böhler
    I need some way to loop in a single line. Is there a way to simulate new lines in AutoIt? Because if I try While 1 MsgBox (0,1,2) Wend It will not work. So I was wondering if there is a way to simulate a new line, something like While 1 - MsgBox (0,1,2) - Wend Or some function to do this. I also already tried to make this: Func repeat($func, $limit) $i = 0 While $i <= $limit Execute($func) $i = $i + 1 WEnd EndFunc But it only executes Execute($func) once, even if I change While $i <= $limit for While 1. I have tried Execute("While $i <= 5" & @LF & "MsgBox(0, 1, 24)" & @LF & "$i = $i + 1" & @LF & "WEnd") too, it doesn't work even if I change @LF for @CRLF, @CR, Chr(13), \n, \r... Any ideas?

  • Why was the arguments.callee.caller property deprecated in JavaScript?

    - by pcorcoran
    Why was the arguments.callee.caller property deprecated in JavaScript? It was added and then deprecated in JavaScript, but it was omitted altogether by ECMAScript. Some browser (Mozilla, IE) have always supported it and don't have any plans on the map to remove support. Others (Safari, Opera) have adopted support for it, but support on older browsers is unreliable. Is there a good reason to put this valuable functionality in limbo? (Or alternately, is there a better way to grab a handle on the calling function?)

  • innerHTML of dynamically added element not updating in Chrome

    - by Sara Chipps
    I'm modifying a dynamically created input element by setting the innerHTML, when I view the element in the DOM Inspector I can see that the values I passed are in the input. However, I can't see it on the page? Is there a refresh() function that I should be calling after setting the value? I have tried innerText, and value and gotten the same results. Here is how I am setting it: $("input[name='group']")[0].innerHTML = groups; (as far as the JS set and the JQuery selector I have found chrome plugins to be fickle this way)

  • asp:Button is not calling server-side function

    - by Richard Neil Ilagan
    Hi guys, I know that there has been much discussion here about this topic, but none of the threads I got across helped me solve this problem. I'm hoping that mine is somewhat unique, and may actually merit a different solution. I'm instantiating an asp:Button inside a data-bound asp:GridView through template fields. Some of the buttons are supposed to call a server-side function, but for some weird reason, it doesn't. All the buttons do when you click them is fire a postback to the current page, doing nothing, effectively just reloading the page. Below is a fragment of the code: <asp:GridView ID="gv" runat="server" AutoGenerateColumns="false" CssClass="l2 submissions" ShowHeader="false"> <Columns> <asp:TemplateField> <ItemTemplate><asp:Panel ID="swatchpanel" CssClass='<%# Bind("status") %>' runat="server"></asp:Panel></ItemTemplate> <ItemStyle Width="50px" CssClass="sw" /> </asp:TemplateField> <asp:BoundField DataField="description" ReadOnly="true"> </asp:BoundField> <asp:BoundField DataField="owner" ReadOnly="true"> <ItemStyle Font-Italic="true" /> </asp:BoundField> <asp:BoundField DataField="last-modified" ReadOnly="true"> <ItemStyle Width="100px" /> </asp:BoundField> <asp:TemplateField> <ItemTemplate> <asp:Button ID="viewBtn" cssclass='<%# Bind("sid") %>' runat="server" Text="View" OnClick="viewBtnClick" /> </ItemTemplate> </asp:TemplateField> </Columns> </asp:GridView> The viewBtn above should call the viewBtnClick() function on server-side. I do have that function defined, along with a proper signature (object,EventArgs). One thing that may be of note is that this code is actually inside an ASCX, which is loaded in another ASCX, finally loaded into an ASPX. Any help or insight into the matter will be SO appreciated. Thanks! (oh, and please don't mind my trashy HTML/CSS semantics - this is still in a very,very early stage :p)

  • Create a dynamic control and AddHandle WITH Values/Brackets

    - by Jacob Kofoed
    Hi, it seems that adding for example a button Dim myButton as New Button and then addHandler to mySub("lol", 255) is not possible. Where mySub is Shared Sub MySub(byRef myString as string, myInteger as Integer) So: addHandler myButton.click, addressOf mySub("lol", 255) - returns an error saying it does not work with parentheses or whatever. I somehow see why this might not be possible, so I'm looking for a work-around on this problem. Please help _jakeCake

  • Want to create an SQL function that removes table row duplicates [migrated]

    - by Hoser
    I'd be following the procedure outlined here (unless of course someone has a better way to do it), and I'm wondering if I could just have some help being pointed in the right direction on how to start. Basically I need help first on HOW to create functions, and general tips on making it adjustable for varying number of columns etc. This may be a very complicated task, as I have no previous experience making SQL functions, so please let me know if this is a difficult task for an SQL noobie working with MS SQL 2005.

  • How to use traceit to report function input variables in stack trace

    - by reckoner
    Hi, I've been using the following code to trace the execution of my programs: import sys import linecache import random def traceit(frame, event, arg): if event == "line": lineno = frame.f_lineno filename = frame.f_globals["__file__"] if filename == "<stdin>": filename = "traceit.py" if (filename.endswith(".pyc") or filename.endswith(".pyo")): filename = filename[:-1] name = frame.f_globals["__name__"] line = linecache.getline(filename, lineno) print "%s:%s:%s: %s" % (name, lineno,frame.f_code.co_name , line.rstrip()) return traceit def main(): print "In main" for i in range(5): print i, random.randrange(0, 10) print "Done." sys.settrace(traceit) main() Using this code, or something like it, is it possible to report the values of certain function arguments? In other words, the above code tells me "which" functions were called and I would like to know "what" the corresponding values of the input variables for those function calls. Thanks in advance.

  • FluentNhibernate dynamic runtime mappings.

    - by Paul Knopf
    I am building a framework where people will be able to save items that the created by inheriting a class of mine. I will be iterating over every type in the appdomain to find classes that I want to map to nhibernate. Every class that I find will be a subclass of the inherited type. I know how to create sub types in FluentNhibernate, but every sub type requires its own ClassMap class. Since I won't know these untill runtime, there is no way I can do that. Is there a way that I can add mappings to fluent nhibernate? Note, I know this is possible without fluent nhibernate using the Cfg class, but I don't want to manage the same code two different ways.

  • Tracing or Logging Resource Governor classification function behavior in Sql Server 2008

    - by nganju
    I'm trying to use the Resource Governor in SQL Server 2008 but I find it hard to debug the classification function and figure out what the input variables will have, i.e. does SUSER_NAME() contain the domain name? What does the APP_NAME() string look like? It's also hard to verify that it's working correctly. What group did the function return? The only way I can see this is to fire up the performance monitor and watch unblinkingly for little blips in the right CPU counter. Is there some way I can either run it in Debug mode, where I can set a breakpoint and step through and look at variable values, or can I at least do the old-school method of writing trace statements to a file so I can see what's going on? Thanks...

  • Dynamic memory managment under Linux

    - by petersohn
    I know that under Windows, there are API functions like global_alloc() and such, which allocate memory, and return a handle, then this handle can be locked and a pointer returned, then unlocked again. When unlocked, the system can move this piece of memory around when it runs low on space, optimising memory usage. My question is that is there something similar under Linux, and if not, how does Linux optimize its memory usage?

  • Treat a void function as a value

    - by Brendan Long
    I'm writing some terrible, terrible code, and I need a way to put a free() in the middle of a statement. The actual code is: int main(){ return printf("%s", isPalindrome(fgets(malloc(1000), 1000, stdin))?"Yes!\n":"No!\n") >= 0; // leak 1000 bytes of memory } I was using alloca(), but I can't be sure that will actually work on my target computer. My problem is that free returns void, so my code has this error message: error: void value not ignored as it ought to be The obvious idea I had was: int myfree(char *p){ free(p); return 0; } Which is nice in that it makes the code even more unreadable, but I'd prefer not to add another function. I also briefly tried treating free() as a function pointer, but I don't know if that would work, and I don't know enough about C to do it properly. Note: I know this is a terrible idea. Don't try this at home kids.

  • JSF dynamic ui:include

    - by Ray
    In my app I have tutor and student as roles of user. And I decide that main page for both will be the same. But menu will be different for tutors and users. I made to .xhtml page tutorMenu.xhtml and student.xhtml. And want in dependecy from role include menu. For whole page I use layout and just in every page change content "content part" in ui:composition. In menu.xhtml <h:body> <ui:composition> <div class="menu_header"> <h2> <h:outputText value="#{msg['menu.title']}" /> </h2> </div> <div class="menu_content"> <?:if test="#{authenticationBean.user.role.roleId eq '2'}"> <ui:include src="/pages/content/body/student/studentMenu.xhtml"/> </?:if> <?:if test= "#{authenticationBean.user.role.roleId eq '1'}"> <ui:include src="/pages/content/body/tutor/tutorMenu.xhtml" /> </?:if> </div> </ui:composition> I know that using jstl my be not better solution but I can't find other. What is the best decision of my problem?

  • How to pass dynamic values using MVC AJax.BeginForm

    - by Arthur
    I'm using MVC and AJax.BeginForm to do some ajax updating of my page. The BeginForm code looks something like: using (Ajax.BeginForm("HandleCrop", "Card", new { accept = true, id = Model.ImageUpload.ID, file = Model.ImageUpload.File, imageCropX = Model.CropInfo.X, imageCropY = Model.CropInfo.Y, imageCropWidth = Model.CropInfo.Width, imageCropHeight = Model.CropInfo.Height }, new AjaxOptions { HttpMethod = "POST", OnComplete = "ConfirmCompleted", OnSuccess = "ReloadUpload", OnFailure = "Failure" }, null)) The Model.CropInfo is being put in as hidden fields like so: <%=Html.HiddenFor(m => m.CropInfo.X) %> <%=Html.HiddenFor(m => m.CropInfo.Y) %> <%=Html.HiddenFor(m => m.CropInfo.Width) %> <%=Html.HiddenFor(m => m.CropInfo.Height) %> However, these values are being dynamically modified by some client side javascript, and these values need to be posted through the Ajax call back to the server. The above code will obviously not work as the imageCrop.. parameters in the Ajax form are being filled when the page is rendered (therefore being all 0). My question is: what is the correct way to approach this situation?

  • Select return dynamic columns

    - by Ascalonian
    I have two tables: Standards and Service Offerings. A Standard can have multiple Service Offerings. Each Standard can have a different number of Service Offerings associated to it. What I need to be able to do is write a view that will return some common data and then list the service offerings on one line. For example: Standard Id | Description | SO #1 | SO #2 | SO #3 | ... | SO #21 | SO Count 1 | One | A | B | C | ... | G | 21 2 | Two | A | | | ... | | 1 3 | Three | B | D | E | ... | | 3 I have no idea how to write this. The number of SO columns is set to a specific number (21 in this case), so we cannot exceed past that. Any ideas on how to approach this? A place I started is below. It just returned multiple rows for each Service Offering, when they need to be on one row. SELECT * FROM SERVICE_OFFERINGS WHERE STANDARD_KEY IN (SELECT STANDARD_KEY FROM STANDARDS)

  • What is XcvPort (used in OpenPrinter function)

    - by RiskX
    I'm usin the OpenPrinter function and the first parameter the function gets called "pPrinterName" and that's it's MSDN description: [in] Pointer to a null-terminated string that specifies the name of the printer or print server, the printer object, the XcvMonitor, or the XcvPort. For a printer object use: PrinterName,Job xxxx. For an XcvMonitor, use: ServerName,XcvMonitor MonitorName. For an XcvPort, use: ServerName,XcvPort PortName. Obviously I'm interested in the bold part. What exactly is XcvPort? I know it seems like a question of lazy person but I really couldn't find info abou this concept. If I would like to open a printer on port ABC I should write: "\\MySrever,XcvPort ABC"? Thank you for your answers!

  • Setting asp:Image URL using Javascript function

  • C++ Function Template With Flexible Return Type

    - by Ignatius Reza
    Let's say that we have a function like so template <class T, class T2> T getMin(T a, T2 b) { if(a < b) return a; return b; } if we call the function like so int a, b; long c; a = getMin(b, c); if c is < a, then the value of c will be type casted to int. Is it possible to make the return type flexible so that it would return an int, or long, or any other type considered smaller by "<" without being type casted?

  • Dynamic creation of VS Project

    - by Adkins
    I have a project where I create WiX (Windows Installer for XML) files, when they are not already present. It is working perfectly. Now I want to expand it to add more functionality. I was wondering if there is a way to create a Visual Studio project programmatically? This project is run as part of our nightly build process, and when a new wix file is needed it is created, but I want to have everything in place when the build is finished so if necessary you can just open the project in Visual Studio and start editing. Am I dreaming outside the realm of possibility or no? Any nudge in the right direction will be greatly appreciated.
