• cache problem in asp.net

  - by JoelFan

  I'm seeing an issue of some static pages that are using the browser cache, which is not desired. To prevent caching, I'm setting <clientCache cacheControlMode="DisableCache" /> in the relevant <location> tag in web.config If I open the page in Firebug (in the Net tab), I see that the Response headers have Cache-Control: no-cache which is correct, but the status of the Response is 304 Not Modified! Isn't that a contradiction? How can I get it to stop caching (i.e. always send a 200 with content)?

• Resize and center image in html/css?

  - by Derek

  Is there a way I can resize, crop, and center an image using html/css only? (img tag or css sprite) For example if I have a 500x500 pixel image, I want to resize that to a 250x250 pixel image I want to make the actual visible image to be 100x100, but still have the scale of a 250x250 sized image. I want the center of the image to be at a location x,y. Is that possible with only html/css, if not, how do you propose I go about it with javascript? Edit - ????: For (2), say my scaled image is now 200x200, and I want my visible image to be 100x100: So I guess what I mean is I want the scale and resolution of the image to be 200x200 but I want the visible image to be 100x100 or in other words the visible image would be at coordinates x,y: 0,0; 0,100; 100,0; 100,100; of the 200x200 image. Sorry, but I'm not good at explaining this.

• Figuring out Host's Top Domain with Javascript

  - by timeitquery

  Is there a way to figure out what the top domain for the hostname of the current page is? The problem I have is that the script could be on .com domain, or in an international domain like .co.uk So for: jobs.telegraph.co.uk - top domain is:telegraph.co.uk jobs.nytimes.com - top domain is nytimes.com The problem is that location.hostname , and the document.domain give the entire domain. One route is to have a list of all TLDs (too much to carry around) and parse based on that. Another route was if 2 characters after last ".", than internationaltion - hence last two are the TLD, but that does not hold true for all international domains.

• Finding vars from dynamically created namespaces in clojure

  - by Tom Crayford

  The following test fails: (ns clojure_refactoring.rename-fn-test (:use clojure.test)) (deftest test-fn-location (in-ns 'refactoring-test-fn-rename) (clojure.core/refer-clojure) (defn a [b] (inc b)) (in-ns 'clojure_refactoring.rename-fn-test) (is (not= (find-var 'refactoring-test-fn-rename/a) nil)) (remove-ns 'refactoring-test-fn-rename)) That is, find-var (of a var I've just created, in a namespace I've just create) returns nil. This behaviour doesn't happen at the repl, where typing out the steps of the test works just fine. Am I doing something wrong, or is this just something that doesn't work in clojure right now?

• What environment variables available while starting the script using init.d boot process

  - by raj_arni

  My problem is like this (OS is Sun Solaris): 1) At the boot time I want to start a process using a specific script. I am doing this by putting this script in /etc/init.d (and following other K and S rules) 2) The program which will be called by the script is located at $HOME/xxx/yyy location. 4) I am using 'su - {myuser} -c "{full path of the program}"' in order to execute the script as {myuser} 3) I dont want to hardcode the value of $HOME in the script but want to use the $HOME env variable only. How can I get this $HOME env variable in the shell script? Also what other variables will be available to me?

• need help revising this javascript that opens to a new window on submit/post

  - by Brad

  I have a form that once you select from a drop-down list and select submit, it is suppose to open up to a new window Here is the code that is currently on the page and I think it needs to be completely wiped out or revised, it only works in IE and Firefox <SCRIPT LANGUAGE="JavaScript" TYPE="text/javascript"> //<!-- Hide JavaScript from older browsers // Function to open a window function windowOpen(window_url) { helpWin = window.open(window_url,'','toolbar=yes,status=no,scrollbars=yes,menubar=yes,resizable=yes,directories=no,location=no,width=350,height=400'); if (document.images) { if (helpWin) helpWin.focus() } } // End script hiding --> </SCRIPT>

• Accessing C++ Functions From Text storage

  - by Undawned

  I'm wondering if anyone knows how to accomplish the following: Let's say I have a bunch of data stored in SQL, lets say one of the fields could be called funcName, function name would contain data similar to "myFunction" What I'm wondering is, is there a way I can than in turn extract the function name and actually call that function? There's a few ways I can think of to accomplish this, one is changing funcName to funcId and linking up with an array or similar, but I'm looking for something a bit more dynamic that would allow me to add the data on fly without having to update the actual source code every time I add a call to a new function assuming of course that the function already exists and is accessible via scope location we call it from. Any help would be greatly appreciated.

• (PHP)how to hold javascript alertbox on screen

• subviews show confused rotated state after a modal dialog is displayed

  - by deafgreatdane

  I've created a custom UIViewController that mimics the UISplitViewController. It manages two child view controllers that get displayed in the left & right body area while in landscape and hides the left to show in a popover when in portrait. It works fine, using the didRotateFromInterfaceOrientation: and willRotateToInterfaceOrientation: messages to reset the location and sizing of the child views. All the views and child controllers are loaded from a nib. This custom view controller is shown inside a UINavigationController. The trouble arises after one of the child view controllers uses presentModalViewController. If the device was rotated after the views were initialized (but before the modal controller is shown), after the modal dialog is dismissed, the left and/or body views will be re-rendered in a different rotation than they were before the modal dialog was changed. I'm wondering if folks have had a similar problem, and what the solution is. I'm sure sample code would be helpful, but it'll take a bunch of work to distill it into a runnable sample.

Then when a user clicks on an item i need a popup with options to route there using google maps navigation, or view mobi site, phone, or email. I am new to android. Please assist. Have gone through the overlay tut but no indication on how to get the info from db. Is there a tut somwhere so i can see some example code to do this?

• How suitable is a DVCS for the corporate environment?

  - by Matt Brailsford

  I've been using SVN for some time now, and am pretty happy with how it works (but I can't say I'm an expert, and I haven't really done much with branches and merging). However an opportunity has arisen to put in some new practises on a new team and so I thought I'd take a look at DVCSs to see if it's worth making the jump. The company I work for is a pretty standard company where we all work in the same location (or sometimes at home) and we want to keep a central store of all code. My question is: if all you are doing with a DVCS is creating a central hub that everyone pushes their changes to, is there really any benefit to moving to a DVCS and its extra overheads in this sort of environment?

• Drupal questions - customizing form_altered modules

  - by bert

  This week I have figured out how to modify form elements in the location module using form_alter and the custom element hook_elements() see: see http://stackoverflow.com/questions/2637052/need-some-tips-on-drupal-form-value I was able to to hide elements using unset eg: unset($element['locpick']['user_latitude']); Also added css with drupal_add_css to hide unwanted groups, and change margins, borders & padding However, I have a few questions - how can I add additional text header between fields? - how can I change input field length? - is it possible to move fields around or put them in a table? reference: http://tinyurl.com/y6ugwtd

• iPhone developing FOR jailbroken devices (not USING jailbroken devices!)

  - by Marek

  I would like to dig into developing for jailbroken devices, just to test what the device could do. I would like, for instance, to alter the ipod music based on geo-location, so i have to program a new daemon that runs in background and fetch gps informations at regular interlavs and then make something with them. Longitude, longitude, for instance, does exactly this, even when the device is locked, and then upload the informations on google latidude. I have some experience as an iphone developer, but i'm not sure on where to find documentation to accomplish such a task. I know about the books "iphone open application development" and "the iphone developer's coockbook", but i don't own them and i'm not sure they have what i'm looking for. Any advice on this?

• Simple, Custom Parsing with c++

  - by bradkovach

  Hi! I have been reading SO for some time now, but I truly cannot find any help for my problem. I have a c++ assignment to create an IAS simulator. Here is some sample code... 0 1 a 1 2 b 2 c 3 1 10 begin 11 . load a, subtract b and offset by -1 for jump+ 11 load M(0) 12 sub M(1) 13 sub M(3) 14 halt Using c++, I need to be able to read these lines and store them in a "memory register" class that I already have constructed... For example, the first line would need to store "1 a" in register zero. How can I parse out the number at the line beginning and then store the rest as a string? I have setup storage using a class that is called using mem.set(int, string);. int is the memory location at the beginning of the line and string is the stored instruction.

• Can VBScript determine the most recently modified (or added) file in a particular folder?

  - by Jimminy

  Hello, I have a script (or more accurately WILL have a script) that checks a folder and copies a file from this folder to a different location (will run once per day). The fileName that I'd like to copy from, however, changes based on the date. Basically, instead of setting the "strFilePath" to "C:\somePath\somePath2\myFile.txt" I would like to simply take the most recently modified (or added - does this make a difference in terms of the script??) in the "somePath2" folder and copy it to the destination. Bonus (but not completely necessary) would be to check in the script if the file was modified/added in the last 24 hours and only copy it over in that case. Thanks for your help!

• How to separate model and view with Core Data?

  - by andrewebling

  I have a subclass of UIView which draws itself based on data held in a corresponding model class, which is a subclass of NSManagedObject. The problem is, some fields in the data model (e.g. the position of the view) are already held in the view (i.e. the frame property in this case). I then have a data duplication/synchronization problem to solve. To complicate matters further, the view needs to update in response to changes made to the data model and the data model needs to be updated in responses made to the view (e.g. the user dragging it to a new location). What's the best way to solve this? Using KVO and references in both directions? Or is there a better approach?

• Right-click on a Listbox in a Silverlight 4 app.

  - by AngryHacker

  I am trying to implement what I used to take for granted in Winforms applications. I am a Silverlight noob, so hopefully all this is elementary. I have a listbox in a Silverlight 4 app. I'd like to do the following: Right-click on the listbox Have the item under the location where I click highlight itself I'd like a context menu to popup (with my own items in the context menu) From my research so far, it appears that there is no ContextMenu construct in Silverlight, instead we have to build up a Grid/Canvas structure and attach it to a Popup object, which is what is then popped up. My questions are as follows: To accomplish #2, I need some kind of hit test on the listbox. I can't figure out how to do that and my google-fu isn't helping. Once I do identify the index under the mouse, how do I actually select the item? Is there a reusable Context menu component somewhere that I can use? Extra credit if the component allows arbitrary sub-menus.

• MyLocationOverlay dissappears, is not there onResume.

  - by Paul

  I have a mapView to which I add a MyLocationOverlay. It displays fine when the app starts from scratch (goes through onCreate). If I exit the app (back button) and then start it again (onResume), the overlay is gone. I have tried to fix this for 10+ hours. All sorts of messing with re-adding the overlay. Resetting the overlays. Changing the maps location so it's forced to redraw. Trying to manually invalidate or force a redraw of the overlay. NOTHING has worked. From the way the code looks, the Overlay object exists and everything is working fine - but it's just not on the map. Is anybody else having this problem? (Droid Incredible, 2.2)

• CruiseControl.NET Silverlight Unit Tests Interact with Desktop Windows Server 2008

  - by user292195

  Hi, Currently we have CCService running as a Domain account because the build scripts deploy to a network location. However this causes any unit tests that test the view to fail. Due to not being allowed to interact with desktop. I can change the CCService to run as local system which works however i loose network connectivity. I also have tried setting up a /interactive cmd.exe but this has been deprecated in Windows Server 2008. Any Ideas on this one? Thanks Jeremy

• Java EE and JDK

  - by user269799

  I want to move from Java SE to Java EE. I will be using some of the sample projects that come with the Java EE. I have uninstalled the JDK but I think this may have been a mistake? When I download the latest Java EE (6), upon installation it asks me for the location of the JDK (which is uninstalled). I was under the impression that the JDK was specific to each version of Java i.e. SE or EE. Am I wrong here? I would have thought that when I download Java EE 6 that it was actually the EE JDK? Can anybody please clarify this for me? GF

• Upload a .pdf file to a Sharepoint Document Library using Access vba

  - by Jim Shaffer

  Within an Access 2007 application, I'm creating a static report in .pdf format. I want to create it, then export the static report (not the data itself) to a Sharepoint Document Library. The intent is for it to be a public repository, no versioning. Each report will carry a unique name. I'm a seasoned vba programmer, but using Sharepoint services is new to me. How do I go about doing this? Assume I can identify the file name and location after I've generated it, and I know the Sharepoint library URL, and have permissions. Where do I go from there?

• How can I use computer vision to find a shape in an image?

  - by Ryan

  I have a simple photograph that may or may not include a logo image. I'm trying to identify whether a picture includes the logo shape or not. The logo (rectangular shape with a few extra features) could be of various sizes and could have multiple occurrences. I'd like to use Computer Vision techniques to identify the location of these logo occurrences. Can someone point me in the right direction (algorithm, technique?) that can be used to achieve this goal? I'm quite a novice to Computer Vision so any direction would be very appreciative. Thanks!
