• Override HTML Anchor Link Target inside iFrame

  - by wag2639

  We're calling an ad from an ad network to dynamically load an add using JavaScript. It makes an iFrame with the actual ad in it, a picture wrapped in an anchor tag with the target=_top. Is there a way from our page to change its target and capture the attempt to change our page. Also, our page is loaded in a C#.net program using a WebControl (I forget the actual control being used since it was a while ago). We can change the C# code but we really prefer not to because then we'd have to test it and everything. Is there a way to do this with JavaScript or JQuery?

• ASP.NET Validator Controls Slowing Down Page

  - by Calvin Nguyen

  Hi all, I have an UpdatePanel that has user controls dynamically added to it. There can be a few dozen user controls at times. The page / UpdatePanel slows down big time on each postback as more user controls are added. After some digging, I was surprised to find the cause is the various CompareValidator, CustomValidator, RegularExpressionValidator and RequiredFieldValidator controls that exist on each user control. Dose anyone have suggestions? It strikes me as very peculiar that inclusion of these ASP.NET controls could have such a horrible effect on performance. Thanks, Calvin

• Javascript Object/Array population question

  - by gnomixa

  Is there a difference between: var samples = { "TB10152254-001": { folderno: "TB10152254", ordno: "001", startfootage: "", endfootage: "", tagout: "Y" }, "TB10152254-002": { folderno: "TB10152254", ordno: "002", startfootage: "", endfootage: "", tagout: "Y" }, "TB10152254-003": { folderno: "TB10152254", ordno: "003", startfootage: "", endfootage: "", tagout: "Y" } }; AND var samples = new Array(); samples["TB10152254-001"] = { folderno: "TB10152254", ordno: "001", startfootage: "", endfootage: "", tagout: "Y"}; samples["TB10152254-002"] = { folderno: "TB10152254", ordno: "002", startfootage: "", endfootage: "", tagout: "Y" }; samples["TB10152254-003"] = { folderno: "TB10152254", ordno: "003", startfootage: "", endfootage: "", tagout: "Y" }; EDIT: I will re-phrase the question: How do I populate the hash dynamically? I can't do something like samples.TB10152254-003 because i TB10152254-003 is dynamic...so, is that even possible?

• Need help with Zend Framework dynamic Namespaces

  - by Marcus Sjölin

  I want to make my system redirect unknown requests such as www.address.com/a_company to the adress www.address.com/companies/company/ and display the company a_company if it exists in the database, otherwise throw the user to a 404 not found page. So in detail, I want to make namespace that is as the first example dynamically, if the company exist in the database, I have no problem connecting to the database and retrieving information or finding a way to parse a company name, I just need help how to make my system check and run a function every time the address doesn't exist and show the second page (/companies/company/).. I am using an Acl as well, but I think it should be fine if the page is /companies/company and then possibly add /?c=a_company or similar. Thank you. /Marcus

• Having trouble with Regular Expression and Ampersand

  - by ajax81

  Hi All, I'm having a bit of trouble with regex's (C#, ASP.NET), and I'm pretty sure I'm doing something fundamentally wrong. My task is to bind a dynamically created gridview to a datasource, and then iterate through a column in the grid, looking for the string "A&I". An example of what the data in the cell (in template column) looks like is: Name: John Doe Phone: 555-123-1234 Email: [email protected] Dept: DHS-A&I-MRB Here's the code I'm using to find the string value: foreach(GridViewRow gvrow in gv.Rows) { Match m = Regex.Match(gvrow.Cells[6].Text,"A&I"); if(m.Success) { gvrow.ForeColor = System.Drawing.Color.Red; } } I'm not having any luck with any of these variations: "A&I" "[A][&][I]" But when I strictly user "&", the row does turn red. Any suggestions? Thanks, Dan

• Best Practices for Managed SalesForce App Development?

  - by Fiid

  We're developing applications for AppExchange and are trying to figure out the best way to do development and release management. There are several issues around this: 1) Package Prefixes. We are developing code in unmanaged mode and releasing as managed, so we have to add all the package prefixes into the code. Is there a way to do this dynamically at runtime? Right now we're using an Ant script, which stops us benefitting from the force.com IDE plugin. 2) Resource files... We are doing some ajax-ey stuff and as a result have a few different resource files we upload, some of which are multiple file resources (zip files). Has anyone automated the building of these resources using ANT, and does that work well? Our environment seems very fragile and works for some developers and not others; have other people had this problem? How did you resolve it?

• Recursive TreeView in ASP.NET

  - by waqasahmed

  I have an object of type list from which I wish to use to populate a treeview in asp.net c#. Each object item has: id | Name | ParentId so for example: id | Name | ParentId ------------------------- 1 | Alice | 0 2 | Bob | 1 3 | Charlie | 1 4 | David | 2 In the above example, the parent would be Alice having two children Bob and Charlie. David is the child of Bob. I have had many problems trying to dynamically populate the treeview recursively in c# ASP.NET Does any one have a simple solution? Btw: you can use People.Id, People.Name and People.ParentId to access the members since it is an object belonging to list. I can post you my code so far (many attempts made) but not sure how useful it will be.

• JavaScript: Reference a functions local scope as an object

  - by eBusiness

  When I call a function, a local scope is erected for that call. Is there any way to directly reference that scope as an object? Just like window is a reference for the global scope object. Example: function test(foo){ var bar=1 //Now, can I access the object containing foo, bar, arguments and anything //else within the local scope like this: magicIdentifier.bar } Alternately, does anyone have a complete list of what is in the global scope on top of custom variables? Background: I'm trying to get down to a way of completely shifting to global scope from within a function call, the with statement is a joke, call works a little better, but it still breaks for anything declared in function scope but not in global scope, therefore I would declare these few cases in global scope, but that requires me to know what they are. The IE function execScript makes a complete shift, but that only solves the problem for IE. Note: To anyone loading JavaScript dynamically, setTimeout(code,1) is a simple effective hack to achieve global scope, but it will not execute immediately.

• Efficiently Combine MatchCollections in .Net Regex

  - by Laramie

  In the simplified example, there are 2 Regular Expressions, one case sensitive, the other not. The idea would be to efficiently create an IEnumerable collection (see "combined" below) combining the results. string test = "abcABC"; string regex = "(?<grpa>a)|(?<grpb>b)|(?<grpc>c)]"; Regex regNoCase = new Regex(regex, RegexOptions.IgnoreCase); Regex regCase = new Regex(regex); MatchCollection matchNoCase = regNoCase.Matches(test); MatchCollection matchCase = regCase.Matches(test); //Combine matchNoCase and matchCase into an IEnumerable IEnumerable<Match> combined= null; foreach (Match match in combined) { //Use the Index and (successful) Groups properties //of the match in another operation } In practice, the MatchCollections might contain thousands of results and be run frequently using long dynamically created REGEXes, so I'd like to shy away from copying the results to arrays, etc. I am still learning LINQ and am fuzzy on how to go about combining these or what the performance hits to an already sluggish process will be.

• IDataServiceMetadataProvider / ResourceType.... what for dynamic types with no CLR type?

  - by TomTom

  Hello, I try to expose a database via ADO RIA for which we have only an ODBC based interface. The "database" is a server and new elements are developped all the time, so I would like the server to check metadata at start (using the odbc schema methods) and then expose what he finds via RIA services.... clients can the nregenerate when they need access to new elements. As such, I dont ahve any CLR types for all the tabled developped. ResourceType tableType = new ResourceType( typeof(object), ResourceTypeKind.EntityType, null, "Martini", table_name, false ); tableType.CanReflectOnInstanceType = false; I can somehow not put in NULl as CLR element type, and entering typeof(object) seems to result in reflection errors when trying to access the properties. Any documentation on how to do that? I dont really want to get into having types... though if I have to, I probably will dynamically generate some via bytecode emit.

• 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

• Windows Forms Autosizing in .NET

  - by mcoolbeth

  My C# project contains a form. There are some controls across the top of the form and some controls across the bottom of the form, as well as a FlowLayoutPanel in the center, all of which have been placed with the Visual Studio Form Designer. During runtime, controls are dynamically added to and removed from the FlowLayoutPanel, and both the panel and the form itself are configured to automatically fit the size of they're contents. However, since some controls were placed with the designer above and below the FlowLayoutPanel, the desired resizing fails to take place when new controls are added to the FlowLayoutPanel. Does anybody know of a convenient remedy for this problem?

• Update frequency for dynamic favicons

  - by rosscowar

  I wanted to learn how to dynamically update the favicon using the Google Chrome browser and I've noticed that the browser seems to throttle how often you can update the favicon per second and that sort of makes things look sloppy. The test page I've made for this is: http://staticadmin.com/countdown.html Which is simply a scrolling message displaying the results of a countdown. I added an input field to tweak how many pixels per second are moved by the script and I've eyeballed the max to be about 5 frames per second smoothly in Google Chrome and I have not tested it in any other browsers. My question is what is the maximum frequency, are there any ways to change, is there a particular reason behind it? NOTE: I've also noticed that this value changes based on window focus as well. It seems to drop to about 1 update per second when the browser's window isn't in focus and returns to "max" when you return.

• IComponentActivator Instance

  - by jeffn825

  How can I use an IComponentActivator instance for a component, not just specifying a type. That is, instead of Component.For<XYZ>.Activator<MyComponentActivator>(); I want to be able say Component.For<XYZ>.Activator(new MyComponentActivator(someImportantRuntimeInfo)); Also, is there a way I can choose an activator dynamically for a non specifically registered component? That is, I want to have an activator that looks at the type being resolved, decides if it can activate it, and if not, responsibility for activation should be passed on to the default activator. So basically I want a global IComponentActivator that has the following logic: Create(Type type){ if (ShouldActivate(type)){ DoActivate(type); } else{ // do default activation here somehow } } Thanks!

• Using malloc/free in Objective-C object

  - by Itamar Katz

  I have a class AudioManager with a member of type AudioBufferList *. (This is a struct declared in the CoreAudio framework). Since AudioBufferList is not a NSObject, I cannot retain it, so I have to alloc/free it (correct me if I'm wrong). My question is, where is the 'right' place to free it? Currently I am doing it in the dealloc method of AudioManager. If I understand correctly, this method is invoked automatically once the release message is sent to the instance of AudioManager --- is that true? Is there any other recommended practice regarding using alloc/free on non-objects members of Objective-C objects? Edit: From Apples documentation: Subclasses must implement their own versions of dealloc to allow the release of any additional memory consumed by the object—such as dynamically allocated storage for data or object instance variables owned by the deallocated object. After performing the class-specific deallocation, the subclass method should incorporate superclass versions of dealloc through a message to super: Which makes things a little bit clearer - but more insights are appreciated.

• UILabel not updating

  - by iFloh

  Sorry the basic question, but this bugs me for a while now. I create a details view from a UITable and try to dynamically set its labels, but they are not updating: - (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath { myObject *tmpObj = [[myObject objectAtIndex:indexPath.section] objectAtIndex:indexPath.row]; myViewController *tmpVC = [[myViewController alloc] initWithNibName:@"NIBfile" bundle:nil]; [tmpVC.myLabel setText:tmpObj.myTitle]; // The debugger shows the text: myTitle = "myText" NSLog(@"%@", tmpVC.myLabel); // NSLog SHOWS NULL [self.navigationController pushViewController:tmpVC animated:YES]; [tmpObj release]; } any ideas why the value is not coming through?

• Get Specific part of a String in Javascript

  - by streetparade

  I have a string containing something like this "Hello bla bla bla bla ok, once more bla können. // this is static: it doesn't change This is a text, this also a text. // this is dynamically added text it can change each time My name mysurename // this is also static text www.blabla.com " Now I have content and I have to get the first part of the string and the third part, I want to be able to have 3 parts, I think I have to split it using something like split(); string1 = "Hello bla bla bla bla ok, once more bla können.; string2 = ""; // i have this part string3 ="My name mysurename"; If it helps the first part ends with "können. " and the third part ends with the url above // its a fictional URL

• using second level cache vs pushing objects into the session

  - by AhmetC

  I have some big entities which are frequently accessed in same session. For example, in my application there is a reporting page which consist of dynamically generated chart images. For each chart image on page, client makes requests to corresponding controller and the controller generates images using some entities. I can either use asp.net's session dictionary for "caching" those entities or rely on nhibernate's second level cache support with using cached queries for example. What is your opinion? By the way I will use shared hosting, is second level cache hosting friendly? Thanks.

• Help me with a solution for what could be solutioned by virtual static fields... in FPC

  - by Gregory Smith

  Hi I'm doing an event manager in Freepascal Each event is an object type TEvent (=object), each kind of event must derive from this class. Events are differentiated by an integer identificator, assigned dynamically. The problem is that i want to retrieve the event id of an instance, and i can't do it well. All instances of a class(object) have a unique id = so it should be static field. All classes have a diferent id = so it should be virtual. Event ids are assignated in run time, and can change = so it can't be a simple method In sum, I can't put all this together. I'm looking for an elegant solution, i don't want to write a hardcoded table, actualizing it in every constructor... etc, i'd prefer something taking advantage of the polymorphism Can anyone help me with another technical or design solution? I remark I don't want to use class instead of object construct.(property doesn't work on objects? :(

• Reference app relative virtual paths in .css file

  - by bravo9

  Assume I have an "images" folder directory under the root of my application. How can I, from within a .css file, reference an image in this directory using an ASP.NET app relative path. Example: When in development, the path of ~/Images/Test.gif might resolve to /MyApp/Images/Test.gif while, in production, it might resolve to /Images/Test.gif (depending on the virtual directory for the application). I, obviously, want to avoid having to modify the .css file between environments. I know you can use Page.ResolveClientUrl to inject a url into a control's Style collection dynamically at render time. I would like to avoid doing this.

• search array and get array key

  - by SoulieBaby

  Hi all, I have an array, which I'd like to search for a value in and retreive the array key if it exists, but not sure how to even go about doing that. Here's my array: Array ( [hours] => Array ( [0] => 5 [1] => 5 [2] => 6 [3] => 6 [4] => 8 [5] => 10 ) ) So I'd like to search the hours array for 10, if 10 exists in the array, I want the key (5) to be returned. If that makes sense? Am trying to do it dynamically so the search string (10) will change, but I figure if I can get it working for number 10, I can get it working with a variable number :)

• How do I make a google larger by scale

  - by Hultner

  I've just started using google charts and want to use it in a small project I'm workin on but I've bumped into a problem. The thing is I want the charts rather big at a static size and look good but I'm generating the charts dynamically with php. Now the problem is that I can't get it to scale properly in width but height is perfectly fine. Here's an example chart I've generated: Parameters: cht=bvo&chs=400x400 chd=t:1,4,1 chxr=2,0,4,1 chds=0,4 chco=4d89f9 chxt=x,x,y,y chxl=0:|3|7|26|1:|Correct+answers|3:|People You see how the chart fills the 400px of height but not the width. I've searched and look through the api but I can't get it right.

• How to specify a SEO friendly url like twitter www.twitter.com/<name> using YII framework

  Hi, I am currently using the Yii framework, and I would like to know if anyone has any clue on how to setup a SEO friendly url like www.twitter.com/ automatically in Yii? I know how to do so this manually in the config/main.php but I would like to be able to dynamically generate it. I have been able to do it in Grails as well. In Yii, what I know of is that you need to have another parameter like www.twitter.com/l/, but I do not want that parameter, anyone can share? Thanks.

• Showing all a Gem's build flags

  - by Rob

  This is more a curiosity than necessity question. I've just installed nokogiri again with RubyGems and it is saying "WARNING: Nokogiri was built against LibXML version 2.7.5, but has dynamically loaded 2.7.6" This is easy enough to fix, but it lead to a more general question: how do I see all the configuration options for a rubygem before installing it? I found the easiest way I know how is to visit the gem folder an run "ruby nokogiri-0.0.0/ext/nokogiri/extconf.rb -h" and that shows me it, but there has to be an easier way, right? I was expecting some kind of "sudo gem install nokogiri -- --help" command that would show the build flags. I've searched around a bit but didn't see anything, anybody know how to do this before I go digging into RG's source :)?
