  • Specify only the second parameter in a javascript function

    - by Ben McCormack
    The spec for the jQuery ajax.error function is: error(XMLHttpRequest, textStatus, errorThrown)Function I'm trying to catch the error and display the textStatus, but I can't figure out how to specify only the textStatus without having to put in a variable name for XMLHttpRequest and errorThrown. My code currently looks like this: $.ajax({ type: "POST", contentType: "application/json; charset=utf-8", url: hbAddressValidation.webServiceUrl, data: this.jsonRequest, dataType: "json", timeout: 5, success: function (msgd) { //... }, error: function (a,textStatus,b) { $("#txtAjaxError").val("There was an error in the AJAX call: " + textStatus); } }); You can see in my code that I'm putting variables a and b as placeholders for the first and last variables in the error function. I know that in my success function, I'm only providing one parameter and it works fine, but in that case data is the first parameter. In the case of error, textStatus is the second parameter, but that's the only one I want to specify. Is this possible?

  • Where is the best place to run initialization code for a UITabBarController?

    - by bobobobo
    I have a UITabBarController in my application. I have to perform some customization to the NIB file using code the first time a view embedded in that UITabBarController gets loaded. When applicationDidFinishLaunching occurs, the UITabBarController's views apparently are not loaded -- if I try to modify the view controllers inside a tab bar that the tab bar is to load in applicationDidFinishLaunching, then those changes are ignored. I'm assuming this is because the tab bar didn't finish loading yet. So, I need a good place to put code that will run immediately after a tabbar is fully ready -- i.e. after it has loaded all the views from their respective nib files. I'm finding the only place I can do this is to track the first time viewDidAppear on each individual view controller. Note I can't use viewWillAppear because I need the value of tabBarController.selectedIndex to be accurate, and it is only actually updated after viewDidAppear gets fired, not when viewWillAppear gets fired.

  • unknown column in where clause

    - by ranzy
    $result = mysql_query("SELECT * FROM Volunteers WHERE Volunteers.eventID = " . $var); $sql = mysql_query("SELECT * FROM Members WHERE Members.pid = " . $temp); I am also doing or die(mysql_error()) at the end of both statements if that matter. My problem is that the first statement executes perfectly but in that table I store an attribute called pid. So the second statement is supposed to take that and return the row where it equals that pid so I can get the name. I get an error that says unknown column in 'a2' in 'where clause' where a2 the pid attribute returned from the first statement. Thanks for any help!

  • Watir question regarding selecting a hidden dropdown.

    - by AJ
    Hi, I have two dropdowns, the second dropdown does not show until a choice is made from the first one. Using watir, i can select the first dropdown, and when i watch it, the second one becomes active, but it cannot select it. i just tried the regular select_list using name and id. Here is the code for the second drop down. <td> <input type="hidden" value="1" name="list" id="list"> <script type="text/JavaScript" language="JavaScript"></script> <select> <option value="">1</option> <option value="2">2</option> <option value="3">3</option> </select> </td> I've also notice the value for the hidden field change as i select different options. Thanks for any help

  • Can my app arrange a gdb breakpoint or watch?

    - by Larry Gritz
    Is there a way for my code to be instrumented to insert a break point or watch on a memory location that will be honored by gdb? (And presumably have no effect when gdb is not attached.) I know how to do such things as gdb commands within the gdb session, but for certain types of debugging it would be really handy to do it "programmatically", if you know what I mean -- for example, the bug only happens with a particular circumstance, not any of the first 11,024 times the crashing routine is called, or the first 43,028,503 times that memory location is modified, so setting a simple break point on the routine or watch point on the variable is not helpful -- it's all false positives. I'm concerned mostly about Linux, but curious about if similar solutions exist for OS X (or Windows, though obviously not with gdb).

  • Jquery interactive table - multiple instance problem

    - by petejm
    Hello forgive me if i use the wrong terminology and the messiness of this code it is the first time I have used jquery. I am making an interactive table-product selector. Compatible systems run along the top and colour choices down the left. The table works by seeing if there is a cell is empty in a html table. If the cell is empty then that is a compatible system and a circle image is in that cell and it is selectable. When selected the product code is generated (by looking at the colour value and system name) and the relevant resource download pack can be downloaded. This works 'fine' when on its own on a page however when I have multiple instances of it on one page they interfere with each other. Only the first one works and clicking in the 2nd 3rd etc table updates the first one. I need these to function independant of each other. I believe the problem is centering around the (this) command working across all of the tables but I can't quite figure this out with what I know of jquery. <script type="text/javascript">// <![CDATA[ jQuery(document).ready(function($j){ $j(document).ready(function() { jQuery.noConflict() (function(){ $j(".options").each(function() { // current td element var tx = $j(this); // do it once only var val = tx.text(); tx.css('background', val ==1 ? '' : 'url(circ.png)'); }); $j("#para").text('').append("Please make a selection");; $j(".options").click(function(e) { $j(".options").each(function() { // current td element var tx = $j(this); // do it once only var val = tx.text(); tx.css('background', val ==1 ? '' : 'url(circ.png)'); }); var ProductCode = 241; var currentCellText = $j(this).text(); var LeftCellText = $j(this).prev().text(); var RightCellText = $j(this).next().text(); var RowIndex =$j(this).parent().parent().children().index($j(this).parent()); var ColIndex = $j(this).parent().children().index($j(this)); var RowsAbove = RowIndex; var ColName = $j(".head").children(':eq(' + ColIndex + ')').text(); var rowid = $j(this).parent().attr('id'); if(currentCellText===''){$j(this).css('background', 'url(circfill.png)'); $j("#para").text('').append( ColName +"-"+ ProductCode +"-"+ rowid +"<br />") $j("#resourcepack").text('').append("Download Selected Resource Pack") $j("#resourcepack").click(function(){ window.location = '241.zip'}); ;} else{$j("#para").text('').append("Incompatible Selection"); $j("#resourcepack").text('').append() }}); }); }); }); </script>

  • Decorator Pattern - Multiple wrappers or quantity property?

    - by Jiminizer
    I'm making use of the decorator pattern for one of the first times, as part of a Uni project. As far as I can see, the pattern seems to be meant more for adding functionality in a modular manner, however we've been taught it with uses such as a coffee or pizza maker, where the object has modular components that are added - changing properties rather than behaviour. I'm trying to make the most of both uses, however I've come up with a question. In the example in the book we're using (Head First Design Patterns), the pattern is used in a coffee shop creating different coffees. So, for example, milk, froth, sugar, sprinkles are all decorators. How would you implement a system that used the same decorator multiple times (for example, a coffee with two sugars)? Would you rewrap the coffee, or give sugar a quantity property? Or (as i'm starting to suspect) would this never be an issue as the pattern isn't designed to be used this way?

Except me :) Thats the reason why i want to know, how high my experience and my knowledge is. Could you tell me, some tips, tricks, test, or anything, on what I can see how much I need to learn and practice to get a mastermind in programming? (at first place in php)

  • MonoRail - Clearing value on edit form submission doesn't trigger validation

    - by Justin
    Hey, In a MonoRail app I have an add/edit view. On add if I don't pick a value for a dropdown I get a validation error and am forced to pick a value. However, if I then edit that same item and reset the dropdown back to the first item ("Select an Item", "0"), it saves and doesn't say it was invalid. Debugging the entity sent back to the server, I can see that it's sending the original value for the dropdown instead of the new value of "0". What's going on here? The first thing I would expect is that it would trigger the validation since the dropdown value isn't set. The second thing I would expect is that it would send the new value I send, not the original. It does send the new value if I change it to another value, but it's as if it has internal logic that says - "I'm updating this entity and a new value was not passed, just don't change the entity value." Thanks, Justin

  • Incrmenting a Cookies with PHP (Beginner Question)

    - by BandonRandon
    Hello, I have used sessions before but never cookies. I would like to use cookies for two reasons: 1) it's something new to learn 2) I would like to have the cookie expire in an hour or so (i know in the code example it expires in 40 sec) I am trying to write a basic if statement that if($counter=="1") { //do this second } elseif ($counter >="2") { //do this every time after the first and second } else {// this is the first action as counter is zero } Here is the code I'm using to set the cookie: // if cookie doesnt exsist, set the default if(!isset($_COOKIE["counter_cookie"])) { $counter = setcookie("counter_cookie", 0 ,time()+40); } // increment it $counter++; // save it setcookie("counter_cookie", $counter,time()+40); $counter = $_COOKIE["counter_cookie"]; The problem is that the counter will be set from 0 to 1 but won't be set from 1 to 2 and so on. Any help would be great I know this is a really simple stupid question :| Thanks!

  • In a graph, how to find the nearest node to a group of nodes?

    - by Nikola
    Hello, I have an undirected, unweighted graph, which doesn't have to be planar. I also have a subset of graph's nodes (true subset) and I need to find a node not belonging to the subset, with minimum sum of distances to all nodes in the subset. So far, I have implemented breath-first search starting from each node in the subset, and the intersection that occurs first is the node I am looking for. Unfortunately, it is running too slow since the graph contains a large number of nodes. Any advice or comment will be appreciated. Thank you, Nikola

  • Display/Hide part of a list

    - by superexsl
    Hi I have an (unordered)list (generated by a repeater) of items. However, I'd like to show the first three items, and have the rest hidden by the main content div. When a button is pressed, I would like the list's div to expand, pushing the main content div down and showing the rest of the list. I was thinking of using slideDown(), but that closes the entire div ( and I would like to show the first 3 items of the list). What would be the best way to achieve an effect like this? Is there a plugin that can easily show X items of a list and the display the rest upon request? Thanks

  • PDF Viewer Showing Last Page...

    - by steve
    I have a asp.net app that writes a pdf to file. Then, later that file is opened into a window (standard acrobat reader) for viewing. No problems there. The weird part... The entire document loads as it should, but the Reader initially shows the last page in the document on the screen. The user must then scroll up to the first page. It doesn't happen all the time (about 50%) and occurs across several test computers. Is there a switch in the code I'm suppose to use in creating the file or displaying the file to tell the reader to "start displaying the document on the first page?" Environment particulars: asp.net 3.5 vb, websupergoo's abcpdf.net pro 7 (assembly that creates the pdf file), Windows 2008 Server, IIS7 Thanks

  • X11 and ARGB visuals: does DefaultDepth() never return 32?

    - by Andy
    Hi, I'm establishing a connection to the X server like this: display = XOpenDisplay(NULL); screen = DefaultScreen(display); depth = DefaultDepth(display, screen); I'm wondering now why "depth" is always set to 24. I would expect that it is only 24 when compositing is turned off, but in fact, it is still 24 even when I turn on compositing. So in order to get a 32-bit ARGB visual I need to call XGetVisualInfo() first with depth set explicitly to 32. Now to my question: Will DefaultDepth() generally never return more than 24 or is it just on my system? (my graphics board is somewhat dated...). I know that it could return 15, 16 or even 8 for a CLUT display but can it return 32? Or do I always have to use XGetVisualInfo() first to get a ARGB 32-bit visual? Thanks, Andy

  • iPhone post-processing with a single FBO with Opengl ES 2.0?

    - by Jing
    I am trying to implement post-processing (blur, bloom, etc.) on the iPhone using OpenGL ES 2.0. I am running into some issues. When rendering during my second rendering step, I end up drawing a completely black quad to the screen instead of the scene (it appears that the texture data is missing) so I am wondering if the cause is using a single FBO. Is it incorrect to use a single FBO in the following fashion? For the first pass (regular scene rendering), I attach a texture as COLOR_ATTACHMENT_0 and render to a texture. glFramebufferTexture2D(GL_FRAMEBUFFER, GL_COLOR_ATTACHMENT0, GL_TEXTURE_2D, texturebuffer, 0) For the second pass (post-processing), I attach the color renderbuffer to COLOR_ATTACHMENT_0 glFramebufferRenderbuffer(GL_FRAMEBUFFER, GL_COLOR_ATTACHMENT0, GL_RENDERBUFFER, colorRenderbuffer) Then use the texture from the first pass for rendering as a quad on the screen.

  • Prototype and jQuery concatenation failure

    - by Corey Hart
    I found something strange when trying to concatenate prototype and jQuery. It seems as though when concatenated, the $ jquery reference doesn't get overwritten by prototype. I've built two test cases to single this out, and it's failing in Chrome8 and FF 3.6. Test Case 1 - Without Concatenation jQuery and Prototype are loaded separately with different script tags. jQuery is loaded first, Prototype second. Test Case 2 - With Concatenation jQuery and Prototype are concatenated into a single file, and loaded with a single script tag. jQuery is first in the script, and prototype is added second. These should act identically, but the second test is throwing errors because the $ function in prototype doesn't overwrite the $ jquery reference. Did I set these up wrong, or are browsers rendering javascript differently when it's all in the same file?

  • Objective-C: Initializing char with char at index of string.

    - by Mr. McPepperNuts
    unichar myChar = [myString characterAtIndex:0]; [myNSMutableArray addObject:myChar]; I am trying to insert the first char of a string into an array, to create an array of chars. the first line does not give me an error. The second line however, provides the following error: warning: passing argument 1 of 'addObject:' makes pointer from integer without a cast This also crashes the application with a "bad address" error. I thought this error was due to a problem with memory allocation. Can someone shed some light on this.

  • How to enable/create elements on the fly

    - by Simon S
    Hi all I am using a combination of PHP, jQuery and Spry to serve a series of listboxes in which a user will select first the type of vehicle, then the make, then the model and finally the specific model. All my listboxes (SELECT) are working fine, and they update properly using the Spry elements. Each listbox is populated from a different Spry XML Dataset, and this is my problem. If I present all four listboxes to the user, the script has to go and fetch all four lots of XML to populate all four listboxes, taking several seconds. What I want to do is to create/enable the listboxes in order, so at the user selects from the first listbox, the second is created/enabled, when they select from the second, the third is created/enabled... and so on. Setting the disabled attribute is no good because the script has already fetched the XML before this is processed. Any ideas?? Si

  • Chain dynamically created dropdowns with JQuery

    - by ricardocasares
    I'm building some kind of indefinite filters for an app, and I'm havin this problem when I clone some selects. The things is this selects are chained between them, trough the Chained Selects jQuery plugin. The problem is that every time I clone the selects, the chaining stops working, and I've tryed everything, such as .live() to make it work, but it seems I'm out of luck :D Here you have a sample of what I'm talking about, http://jsfiddle.net/7K2Eu/63/ At first, the selects chain normally, but when I clone the form, they stop working, except for the first row of selects. Thank you!!

  • grdb not working variables

    - by stupid_idiot
    hi, i know this is kinda retarded but I just can't figure it out. I'm debugging this: xor eax,eax mov ah,[var1] mov al,[var2] call addition stop: jmp stop var1: db 5 var2: db 6 addition: add ah,al ret the numbers that I find on addresses var1 and var2 are 0x0E and 0x07. I know it's not segmented, but that ain't reason for it to do such escapades, because the addition call works just fine. Could you please explain to me where is my mistake? I see the problem, dunno how to fix it yet though. The thing is, for some reason the instruction pointer starts at 0x100 and all the segment registers at 0x1628. To address the instruction the used combination is i guess [cs:ip] (one of the segment registers and the instruction pointer for sure). The offset to var1 is 0x10 (probably because from the begining of the code it's the 0x10th byte in order), i tried to examine the memory and what i got was: 1628:100 8 bytes 1628:108 8 bytes 1628:110 <- wtf? (assume another 8 bytes) 1628:118 ... whatever tricks are there in the memory [cs:var1] points somewhere else than in my code, which is probably where the label .data would usually address ds.... probably.. i don't know what is supposed to be at 1628:10 ok, i found out what caused the assness and wasted me whole fuckin day. the behaviour described above is just correct, the code is fully functional. what i didn't know is that grdb debugger for some reason sets the begining address to 0x100... the sollution is to insert the directive ORG 0x100 on the first line and that's the whole thing. the code was working because instruction pointer has the right address to first instruction and goes one by one, but your assembler doesn't know what effective address will be your program stored at so it pretty much remains relative to first line of the code which means all the variables (if not using label for data section) will remain pointing as if it started at 0x0. which of course wouldn't work with DOS. and grdb apparently emulates some DOS features... sry for the language, thx everyone for effort, hope this will spare someone's time if having the same problem... heheh.. at least now i know the reason why to use .data section :))))

  • How to calculate the time difference between two time fields , with respect to the date changes

    - by Tiru
    I want to calculate the time difference.I have three EditTexts , I want to input the times in the first two edittexts in HH:MM format. And then calculate the time difference and the result will show on third edittext field in same format.
