  • Javascript unable to pass parameters into a property acting as a function

    - by BOverflow
    Currently in a simplified form, my code looks like this function AddFileParam(file_id, name, value) { uploadcontrol.addFileParam(file_id, name, value) } uploadcontrol = new Upload() function upload() { //logic } upload.prototype.AddFileParam = function(file_id, name, value) { //logic }; The code is giving me an error as it states that addFileParam is not a valid function. This is caused by the instance of the function upload (aka. uploadcontrol). This is only occuring in Firefox/Chrome and not in IE. Any ideas on how to fix this?

    - by Luke101
    When load the new html from a post function I lose all of my click bindings. I read that i could use live to keep all the bindings but can't find any examples where live is used with post.

  • Javascript obfuscation and extreme situation in production solving

    - by faya
    Hello, I have a few questions regarding JavaScript obfuscation on client side. First question: What is the best tool or best three tools which ones you could suggest for this operation? Second question: How developers should debug such code (in example with firebug) when extreme situation appears in the production if the code is obfuscated? P.S. - I know that it's bad practice to debug in production, but we had some emergencies and experienced sometimes such situations. Thanks for any help!

  • Choosing the MVC view engine

    - by leonard
    I want to allow the end-users of my web application to modify views (via web based back office), stored in the database. The desired view engine is expected to be code-injection safe, meaning that the end-user will be limited to the absolute minimum number of expressions available, no server code inserts are allowed. Is any suitable view engine available to download?

  • Flex: Is it worth upgrading to Flex 4?

    - by ChrisInCambo
    Hi, I'm in the process of building my first serious Flex application and have started out using Flex 3.4 even though 4.0 was available mainly due to the larger number of resources. But now I feel very comfortable with the Flex API's, is it worth upgrading to Flex 4? What are the benefits? And can I expect much pain when porting my existing code base of only a few thousand lines of code? Cheers, Chris

  • Rails 3: How do I call a javascript function from a js.erb file

    - by user321775
    Now that I've upgraded to Rails 3, I'm trying to figure out the proper way to separate and reuse pieces of javascript. Here's the scenario I'm dealing with: I have a page with two areas: one with elements that should be draggable, the other with droppables. When the page loads I use jQuery to setup the draggables and droppables. Currently I have the script in the head portion of application.html.erb, which I'm sure is not the right solution but at least works. When I press a button on the page, an ajax call is made to my controller that replaces the draggables with a new set of elements that should also be draggable. I have a js.erb file that renders a partial in the correct location. After rendering I need to make the new elements draggable, so I'd like to reuse the code that currently lives in application.html.erb, but I haven't found the right way to do it. I can only make the new elements draggable by pasting the code directly into my js.erb file (yuck). What I'd like to have: - a javascript file that contains the functions prepdraggables() and prepdroppables() - a way to call either function from application.html.erb or from a js.erb file I've tried using :content_for to store and reuse the code, but can't seem to get it working correctly. What I currently have in the head section of application.html.erb <% content_for :drag_drop_prep do %> <script type="text/javascript" charset="utf-8"> $(document).ready(function () { // declare all DOM elements with class draggable to be draggable $( ".draggable" ).draggable( { revert : 'invalid' }); // declare all DOM elements with class legal to be droppable $(".legal").droppable({ hoverClass : 'legal_hover', drop : function(event, ui) { var c = new Object(); c['die'] = ui.draggable.attr("id"); c['cell'] = $(this).attr("id"); c['authenticity_token'] = encodeURIComponent(window._token); $.ajax({ type: "POST", url: "/placeDie", data: c, timeout: 5000 }); }}); }); </script> <% end %> undo.js.erb $("#board").html("<%= escape_javascript(render :partial => 'shared/board', :locals => { :playable => true, :restartable => !session[:challenge]}) %>") // This is where I want to prepare draggables. <%= javascript_include_tag "customdragdrop.js" %> // assuming this file had the draggables code from above in a prepdraggables() function prepdraggables();

  • Merge Mutliple Excel Workbooks

    - by IRHM
    I wonder whether someone may be able to help me please. I'm trying to use the code below to allow the user to select multiple Excel Workbooks, amalgamating the data into one 'Summary' sheet. Sub Merge() Dim DestWB As Workbook, WB As Workbook, WS As Worksheet, SourceSheet As String Set DestWB = ActiveWorkbook SourceSheet = "Input" startrow = 7 FileNames = Application.GetOpenFilename( _ filefilter:="Excel Files (*.xls*),*.xls*", _ Title:="Select the workbooks to merge.", MultiSelect:=True) If IsArray(FileNames) = False Then If FileNames = False Then Exit Sub End If End If For n = LBound(FileNames) To UBound(FileNames) Set WB = Workbooks.Open(Filename:=FileNames(n), ReadOnly:=True) For Each WS In WB.Worksheets If WS.Name = SourceSheet Then With WS If .UsedRange.Cells.Count > 1 Then dr = DestWB.Worksheets("Input").Range("C" & Rows.Count).End(xlUp).Row + 1 lastrow = .Range("C" & Rows.Count).End(xlUp).Row For j = lastrow To startrow Step -1 Select Case .Range("E" & j).Value Case "Manager", "Lead", "Technical", "Analyst" 'do nothing Case Else .Rows(j).EntireRow.Delete End Select Next lastrow = .Range("C" & Rows.Count).End(xlUp).Row If lastrow >= startrow Then .Range("B" & startrow & ":AD" & lastrow).Copy DestWB.Worksheets("Input").Cells(dr, "B").PasteSpecial xlValues .Range("AF" & startrow & ":AQ" & lastrow).Copy DestWB.Worksheets("Input").Cells(dr, "AF").PasteSpecial xlValues .Range("AS" & startrow & ":AS" & lastrow).Copy DestWB.Worksheets("Input").Cells(dr, "AS").PasteSpecial xlValues End If End If End With Exit For End If Next WS WB.Close savechanges:=False Next n End Sub The code works fine except for one issue which I've been trying to solve for the last few weeks. The following line of code looks in column E of the Source file, and if any of the entries match the values shown in the code it copies that row of data to paste into the Destination file. If Range("E" & j) <> "Manager" And Range("E" & j) <> "Lead" And Range("E" & j) <> "Technical" And Range("E" & j) <> "Analyst" Then Rows(j).Delete The problem I have is that if none of these values are found in the Source file, I receive the following error: Run time error '1004': Delete method of range class failed and in Debug mode it highlights this part of the line as the source of the error, but I've no idea why. Rows(j).Delete I just wondered whether someone may be able to look at this please and let me know where I'm going wrong, or perhaps even suggest a more efficient process of allowing the user to merge the workbooks. Many thanks and kind regards

  • Silverlight ItemsControl - change ItemTemplate

    - by Cornel
    I have an ItemsControl with a list of radio buttons - in this case the ItemTemplate will contain a binded radio button. The problem is that in some cases I need to replace the radio button with a check box without using any C# code. Is this possible?

  • Using memcpy to change a jnz to a jmp.

    - by Phil
    Not used memcpy much but here's my code that doesn't work. memcpy((PVOID)(enginebase+0x74C9D),(void *)0xEB,2); (enginebase+0x74C9D) is a pointer location to the address of the bytes that I want to patch. (void *)0xEB is the op code for the kind of jmp that I want. Only problem is that this crashes the instant that the line tries to run, I don't know what I'm doing wrong, any incite?

  • How to clone repository to a remote server/repository with Mercurial

    - by Alex N.
    Found myself quite confused today about this. I create a blank repository locally(hg init), cloned it to working copy, added some code, commited and pushed it(to local repo obviously). Now I need to share that repository with others. There is a server that has mercurial on it, how do I clone my repository to a remote one such that other developers can access it and pull/push code from/to it?

  • prohibiting instantiation as a temporary object (C++)

    - by SuperElectric
    I like using sentry classes in c++, but I seem to have a mental affliction that results in repeatedly writing bugs like the following: { MySentryClass(arg); // ... other code } Needless to say, this fails because the sentry dies immediately after creation, rather than at the end of the scope, as intended. Is there some way to prevent MySentryClass from being instantiated as a temporary, so that the above code either fails to compile, or at least aborts with an error message at runtime?

  • Static lock in Python?

    - by roddik
    Hello. I've got the following code: import time import threading class BaseWrapper: #static class lock = threading.Lock() @staticmethod def synchronized_def(): BaseWrapper.lock.acquire() time.sleep(5) BaseWrapper.lock.release() def test(): print time.ctime() if __name__ is '__main__': for i in xrange(10): threading.Thread(target = test).start() I want to have a method synchronized using static lock. However the above code prints the same time ten times, so it isn't really locking. How can I fix it? TIA

  • Facebook charset detection mechanism?

    - by Void
    Today, I have looked into HTML code of facebook.com, and found something like this: <input type="hidden" value="€,´,€,´,?,?,?" name="charset_test"/> It's repeated two times inside the <form>...</form>. Any idea what this code might be useful for - some kind of server-side client charset detection? As far as I know, browser charset is being transmitted in HTTP request anyway (an "Accept-Charset" header).

  • Javascript: Inline function vs predefined functions

    - by glaz666
    Can any body throw me some arguments for using inline functions against passing predefined function name to some handler. I.e. which is better: (function(){ setTimeout(function(){ /*some code here*/ }, 5); })(); versus (function(){ function invokeMe() { /*code*/ } setTimeout(invokeMe, 5); })(); Strange question, but we are almost fighting in the team about this

  • GCC how to block system calls within a program?

    - by CMPITG
    Does anyone tell me how to block system calls within a program, please? I am building a system which takes a piece of C source code, compiles it with gcc and runs it. For security reasons, I need to prevent the compiled program from calling system calls. Is there any way to do it, from the source code level (e.g. stripping the header files of gcc, detecting malicious external calls, ...) to the executable level?

  • What is the difference between these Pentium Extreme Edition CPUs?

    - by Giffyguy
    The CPU in question is the Pentium Extreme Edition 955. Intel's website shows four "versions", but for the most part they all look identical. They even share the same set of ordering codes. But one of them has a substantially lower TDP, which is seemingly unexplainable - since everything else is the same. Two of them say "LGA775, Tray" and I have no idea what "Tray" means either. Also, two of them have a different SPEC code. What I need to know is: What does "LGA775, Tray" mean? Why does the one CPU have a lower TDP? And what does that mean for me? Does that mean lower maximum power consumption? Does it mean the CPU may be more stable/endurant, because of a lower heat output? Why do two of them have a different SPEC code, and what does this mean? Finally, what does PLGA775 (as opposed to LGA775) mean, and do I need to be worried about that? Information from Intel's wbsite: Intel® Pentium® Processor Extreme Edition 955 (4M Cache, 3.46 GHz, 1066 MHz FSB) with SPEC Code 1 Boxed Intel® Pentium® Processor Extreme Edition 955 4M Cache, 3.46 GHz, 1066 MHz FSB LGA775 PLGA775 B1 95 Watts BX80553955 SL94N 2 Intel® Pentium® Processor Extreme Edition 955 4M Cache, 3.46 GHz, 1066 MHz FSB LGA775, Tray PLGA775 B1 130 Watts HH80553PH0994M SL94N 3 Boxed Intel® Pentium® Processor Extreme Edition 955 4M Cache, 3.46 GHz, 1066 MHz FSB LGA775 PLGA775 B1 130 Watts BX80553955 SL8WM 4 Intel® Pentium® Processor Extreme Edition 955 4M Cache, 3.46 GHz, 1066 MHz FSB LGA775, Tray PLGA775 B1 130 Watts HH80553PH0994M SL8WM

  • API sanity autotest help needed

    I am trying to auto-generate Unit Tests for my C code using API sanity autotest. But, the problem is that it is somewhat complex to use, and some tutorials / howto / other resources on how to use it would be really helpful. Have you had any luck with API sanity autotest? Do you think there's a better tool that can be used to auto-generate unit tests for C code?

  • Issues adding search to iPhone app

    - by Graeme
    Hi, Basically I'm trying to add a search function to my iPhone app, but I'm not having much luck at the moment. I've downloaded the Apple provided Table Search app, and have copied across the code to mine. It builds OK, but here's the problem. Unlike the Apple example, all my data is stored in an array, that is accessed by calling [ciParser.currentArray]. Any ideas on how to change the code to suit my needs? I'm getting an error "Terminating app due to uncaught exception 'NSRangeException', reason: '* -[NSCFArray objectAtIndex:]: index (0) beyond bounds (0)'" whenever I click on the search bar and the app exits. Below is the code in particular that the debugger highlights as being troublesome. Apparently this error means the database trying to be searched is empty, but I could be wrong. FYI my app downloads and parsers an RSS feed using a class which is referenced by ciParser - which in turn stores the downloaded content in an array that I need to search. // Customize the appearance of table view cells. - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { static NSString *CellIdentifier = @"Cell"; UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier]; if (cell == nil) { cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] autorelease]; } /* If the requesting table view is the search display controller's table view, configure the cell using the filtered content, otherwise use the main list. */ CurrentItem * nextCurrentItem=[ciParser.currentArray objectAtIndex:indexPath.row]; if (tableView == self.searchDisplayController.searchResultsTableView) { (Code which debugger points to as being wrong) nextCurrentItem = [self.filteredListContent objectAtIndex:indexPath.row]; } else { nextCurrentItem = [ciParser.currentArray objectAtIndex:indexPath.row]; } NSString*settingValue = [[NSUserDefaults standardUserDefaults]stringForKey:@"state"]; if ([settingValue isEqualToString:@"New South Wales"]) { cell.textLabel.text=nextCurrentItem.title; } else if ([settingValue isEqualToString:@"Western Australia"]) { cell.textLabel.text=@"The FESA does not provide any Current Incident reports."; } else if ([settingValue isEqualToString:@"Victoria"]) { cell.textLabel.text=nextCurrentItem.title; } else if ([settingValue isEqualToString:@"South Australia"]) { cell.textLabel.text=nextCurrentItem.title; } else if ([settingValue isEqualToString:@"Tasmania"]) { cell.textLabel.text=nextCurrentItem.title; } // Set up the cell... [cell setAccessoryType:UITableViewCellAccessoryDisclosureIndicator]; return cell; }
