  • Installing Python in Windows XP

    - by Sam
    My work PC has restrictions that stop me from adding programs to the start menu so when I try to install Python using the Python 2.6.5 Windows installer it can't complete as it tries to add a shortcut to my start menu. Is there a way around this? I.e another way of installing without the need for a shortcut? Edit: I'll also need to install NumPy which I can't do on the Portable version of Python.

  • Day dreaming about automatic RGB color function in PHP

    - by Sam
    Hello fellow earthlings. A quesion about RGB color and its usefulness in a simple tiny php code: Imagine I have variable $colorA containning a valid six char color. say B1B100, a greenish natural color. Now If I would like to make a new color from that, which is, say, ten steps lighter thatn that original color, roughly. $colorA = B1B100 // original color php code with little color engine lightening stuff up goes here $colorB = ?????? // original color lightened up Is there a php ready function that KNOWS rgb colors something like php function RGB ( input color, what to do, output color) Where what to do could be +/- 255 values of brightness etc etc. Is something like this already possible or am I day dreaming? rgb($colorA, +10, $colorB) If this does not exist, what would be the shortest code for doing this? Link suffices. Suggestions and ideas are answers to me. Thanks.

  • Jquery selectors by CSS class in IE is really slow--workarounds?

    - by Sam Lee
    I have a web app where I have several elements with class="classA". I want to select and apply a function to all of them. I am doing the obvious thing, which is $(".classA").each(function () { ... }). This works just fine in Chrome/Safari/Firefox but is really slow in IE. It turns out IE has serious performance issues when selecting things by CSS class in jQuery. I was wondering if anyone has suggestions on good ways to deal with this. I can't use ID selectors because there can be multiple DOM elements I want to select.

  • Eclipse antRunner command line build has wrong dependency build order

    - by Sam Jones
    My team's Eclipse RCP app builds fine from the Eclipse IDE. When I try to build it from the command line, using the antRunner application, it builds the plugins out of order -- a plugin builds before it's dependencies are built, and so can't resolve some of the needed classes. Where should I look to fix this? As far as I can tell, the dependencies are set up correctly (a feature that depends on a plugin that depends on another plugin). I have my build.properties and folder structure set up as specified here. Is there anything else I should look at?

  • Auto convert java source to use generic rather than raw types

    - by Sam
    Is there a way/tool to auto convert Java source code from using raw types to using generic types? I have some legacy code with 677 references to raw types: ArrayList 47 Vector 420 Hashtable 61 Enumeration 64 Class 7 Iterator 78 TOTAL 677 Now I could manually look through the code to infer the generic types and replace, but that is going to take a long time.

  • VS 2008 hangs(slow) when I select "File > Open > Web Site..."

    - by Sam
    When I try to select the following "File Open Web Site" or use the shortcut key "Shift + Alt + O" (which does the same), Visual Studio 2008 hangs with the loading mouse icon for about 8-10 seconds then the file. But if I do "File Open Project/Solution.." or "File Open File..." the explorer window comes up in under a second, instantly most times.

  • Problem storing a hash in DB using Storable::nfreeze in Perl

    - by Sam
    I want to insert a hash in the db using Storable::nfreeze but the data is not inserted properly. My code is as follows: %rec=(); $rec{'name'} = 'my name'; $rec{'address'} = 'my address'; my $order1 = new Order(); $order1->set_session(\%rec); $self->createOrder($order1); sub createOrder { my $self = $_[0]; my $order = $_[1]; # Retrieve the fields to insert into the database. my $st = $dbh->prepare("insert into order (session,.......) values(?,........)"); my $session = %{$order->get_session()}; $st->execute(&Storable::nfreeze(\%session),.....); $st->finish(); } sub getOrder { ... my $session = &Storable::thaw( $ref->{'session'} ); ..... } The thaw is working fine because I tested it withe some rows that have been inserted correctly, but when I try to get a row that was inserted using the createOrder subroutine, I get an error saying: Storable binary image v36.65 more recent than I am (v2.7) at blib/lib/Storable.pm (autosplit into blib/lib/auto/Storable/thaw.al) line 415 The error comes from the line that have thaw. The nfreeze did not store the hash properly. Can someone point me to what I'm doing wrong in the createOrder subroutine? I know the module version have nothing to do with the problem.

  • Android Google-Shopping API force closes while parsing

    - by Sam Jackson
    I'm trying to send a request to the Google-Shopping API with the following static method which I think is working: public static String GET_TITLE(String url) throws JSONException { InputStream is = null; String result = ""; JSONObject jArray = null; // http post try { HttpClient httpclient = new DefaultHttpClient(); HttpPost httppost = new HttpPost(url); HttpResponse response = httpclient.execute(httppost); HttpEntity entity = response.getEntity(); is = entity.getContent(); } catch(Exception e) { Log.e("log_tag", "Error in http connection "+e.toString()); } The URL I'm passing is this BTW: https://www.googleapis.com/shopping/search/v1/public/products/country=US&q=shirts&alt=json &rankBy=relevancy&key=AIzaSyDRKgGmJrdG6pV6DIg2m-nmIbXydxvpjww Next I try to parse this response (where I think the problem comes in) in the same method: try { jArray = new JSONObject(result); } catch(JSONException e){ Log.e("log_tag", "Error parsing data "+e.toString()); } JSONObject itemObject = jArray.getJSONObject("items"); JSONObject productObject = itemObject.getJSONObject("product"); String attributeGoogleId = productObject.getString("googleId"); String attributeProviderId = productObject.getString("providerId"); String attributeTitle = productObject.getString("title");*/ String attributePrice = productObject.getString("price"); JSONObject popupObject = productObject.getJSONObject("popup"); return attributeTitle; } This has been so frustrating, I know it should be simple but everywhere I look I just can't quite get it to work, I'm not exactly sure what the error is since I'm testing it on my HTC Desire because my emulator gives an 'invalid command-line parameter' error when starting, but that's a different issue, anyway, thanks in advance! EDIT: The first one makes it look like there's a problem with the URL, should I change it and see if it makes a difference? 04-01 12:09:05.142: ERROR/log_tag(24968): Error in http connection java.net.UnknownHostException: www.googleapis.com 04-01 12:09:05.142: ERROR/log_tag(24968): Error converting result java.lang.NullPointerException 04-01 12:09:05.142: ERROR/log_tag(24968): Error parsing data org.json.JSONException: End of input at character 0 of 04-01 12:09:05.142: DEBUG/AndroidRuntime(24968): Shutting down VM 04-01 12:09:05.142: WARN/dalvikvm(24968): threadid=1: thread exiting with uncaught exception (group=0x400259f8) 04-01 12:09:05.152: ERROR/AndroidRuntime(24968): FATAL EXCEPTION: main 04-01 12:09:05.152: ERROR/AndroidRuntime(24968): java.lang.RuntimeException: Failure delivering result ResultInfo{who=null, request=0, result=-1, data=Intent { act=com.google.zxing.client.android.SCAN flg=0x80000 (has extras) }} to activity {com.spectrum.stock/com.spectrum.stock.CaptureActivity}: java.lang.NullPointerException 04-01 12:09:05.152: ERROR/AndroidRuntime(24968): at android.app.ActivityThread.deliverResults(ActivityThread.java:3734) 04-01 12:09:05.152: ERROR/AndroidRuntime(24968): at android.app.ActivityThread.handleSendResult(ActivityThread.java:3776) 04-01 12:09:05.152: ERROR/AndroidRuntime(24968): at android.app.ActivityThread.access$2800(ActivityThread.java:135) 04-01 12:09:05.152: ERROR/AndroidRuntime(24968): at android.app.ActivityThread$H.handleMessage(ActivityThread.java:2166) 04-01 12:09:05.152: ERROR/AndroidRuntime(24968): at android.os.Handler.dispatchMessage(Handler.java:99) 04-01 12:09:05.152: ERROR/AndroidRuntime(24968): at android.os.Looper.loop(Looper.java:144) 04-01 12:09:05.152: ERROR/AndroidRuntime(24968): at android.app.ActivityThread.main(ActivityThread.java:4937) 04-01 12:09:05.152: ERROR/AndroidRuntime(24968): at java.lang.reflect.Method.invokeNative(Native Method) 04-01 12:09:05.152: ERROR/AndroidRuntime(24968): at java.lang.reflect.Method.invoke(Method.java:521) 04-01 12:09:05.152: ERROR/AndroidRuntime(24968): at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:868) 04-01 12:09:05.152: ERROR/AndroidRuntime(24968): at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:626) 04-01 12:09:05.152: ERROR/AndroidRuntime(24968): at dalvik.system.NativeStart.main(Native Method) 04-01 12:09:05.152: ERROR/AndroidRuntime(24968): Caused by: java.lang.NullPointerException 04-01 12:09:05.152: ERROR/AndroidRuntime(24968): at com.spectrum.stock.JSONResponse.GET_TITLE(JSONResponse.java:61) 04-01 12:09:05.152: ERROR/AndroidRuntime(24968): at com.spectrum.stock.CaptureActivity.onActivityResult(CaptureActivity.java:78) 04-01 12:09:05.152: ERROR/AndroidRuntime(24968): at android.app.Activity.dispatchActivityResult(Activity.java:3931) 04-01 12:09:05.152: ERROR/AndroidRuntime(24968): at android.app.ActivityThread.deliverResults(ActivityThread.java:3730) 04-01 12:09:05.152: ERROR/AndroidRuntime(24968): ... 11 more 04-01 12:09:05.162: WARN/ActivityManager(96): Force finishing activity com.spectrum.stock/.CaptureActivity

  • Can't append space at end of UITextView

    - by Sam V
    I have a UITextView in which I want the initial value to be "@username " (notice the space after the username). This way the user can start typing right away without having to tap space. So I do: textView.text = [NSString stringWithFormat:@"@%@ ", username]; But it seems like it's impossible to have the UITextView text property ending with a space (it always gets stripped out). Am I correct? Is there any workaround for this? I tried using the \s char and no success.

  • Auto Generate Objects in DBIx::Class ORM in Perl

    - by Sam
    Hello, I started learning DBIx::class and I reach the point where you have to create the Objects that represents tables. Should this classes be created manually ( hard coding all the fields and relationships.....) or there is a way to generate them automatically using the database schema. I read something about loaders, but i did not know where they are really used. Please advice. Thanks

  • How do you get Eclipse/Mylyn to fill out your commit messages for you?

    - by Sam Hasler
    I've setup the following: Installed Mylyn in Eclipse Installed the Bugzilla connector Installed Subversive SVN Integration for the Mylyn Project I've gone to Windows - Preferences - Tasks - Team and clicked Change Set Management and left it with the default Commit Comment Template: ${task.status} - ${connector.task.prefix} ${task.key}: ${task.description} ${task.url} However, if I activate a bugzilla bug in the Task List, and then edit a file, when I commit the changes the commit message isn't filled in. Also, in the Synchronisation perspective there isn't a change set for the task I'm working on. I've tried following the instructions on the Eclipse wiki's Mylyn FAQ for Why does task change set not appear when I modify files? but the bullet point: * Verify that the configured Synchronize View is configured for change sets. points to a section that is no longer in the document. I have a Show Change Sets button, but clicking it only shows me incoming change sets, there aren't any outgoing change sets. What am I missing?

  • No IntelliSense for c++/cli in visual studio 2010?

Is there any way to get this back? It is rather useful...

  • Rails form with a better URL

    - by Sam
    Wow, switching to REST is a different paradigm for sure and is mainly a headache right now. view <% form_tag (businesses_path, :method => "get") do %> <%= select_tag :business_category_id, options_for_select(@business_categories.collect {|bc| [bc.name, bc.id ]}.insert(0, ["All Containers", 0]), which_business_category(@business_category) ), { :onchange => "this.form.submit();"} %> <% end %> controller def index @business_categories = BusinessCategory.find(:all) if params[:business_category_id].to_i != 0 @business_category = BusinessCategory.find(params[:business_category_id]) @businesses = @business_category.businesses else @businesses = Business.all end respond_to do |format| format.html # index.html.erb format.xml { render :xml => @businesses } end end routes map.resources What I want to to is get a better URL than what this form is presenting which is the following: http://localhost:3000/businesses?business_category_id=1 Without REST I would have do something like http://localhost:3000/business/view/bbq bbq as permalink or I would have done http://localhost:300/business_categories/view/bbq and get the business that are associated with the category but I don't really know the best way of doing this. So the two questions are what is the best logic of finding a business by its categories using the latter form and number two how to get that in a pretty URL all through RESTful routes in Rails.

  • Unsuccessful error detection of improperly declared method in GCC 4.2 compiler

    - by sam
    I am using C++ compiler GCC 4.2 in XCode 3.2.2. I have noted that the compiler will successfully compile a method foo even though there are no ellipses. The header and method are properly declared as foo(), but when I do a find and replace either by file or by program-wide it will miss approximately 2-3% of the changes [foo to foo(). This would not be critical if the compiler did not give an erroneous successful build. I have not found that this to occur with: foo(any parameter). Does anyone have any solution? Thank you.

  • Is it possible to have a Ocaml function that accepts only integer lists?

    - by Sam
    I'm writing a recursive function in Ocaml that's supposed to count the number of items in an integer list (Yes I know there's a List.length function but I'm trying to do it myself). However the Ocaml compiler/interpreter forces me to use alpha list all the time. So is it wrong to say that, when a function accepts a list as a parameter, the type of that list must always be alpha? Thanks EDIT: the reason why it's inconvenient for me to use alpha lists is because i can't compare the head of the alpha list with an integer value due to type-matching complaints

  • TFS Folders - Getting them to work like Subversion "Trunk/Tags/Branches"

    - by Sam Schutte
    I recently started using Team Foundation Server, and am having some trouble getting it to work the way I want it to. I've used Subversion for a couple years now, and love the way it works. I always set up three folders under each project, Trunk, Tags, and Branches. When I'm working on a project, all my code lives under a folder called "C:\dev\projectname". This "projectname" folder can be made to point to either trunk, or any of the branches or tags using Subversion (with the switch command). Now that I'm using TFS (my client's system), I'd like things to work the same way. I created a "Trunk" folder with my project in it, and mapped "Project/Trunk/Website" to "c:\dev\Website". Now, I want to make a release under the "tags" folder (located in "Project/Tags/Version 1.0/Website", and TFS is giving me the following error when I execute the branch command: "No appropriate mapping exists for $Project/tags/Version 1.0/Website" From what I can find on the internet, TFS expects you to have a mapping to your hard drive at the root of the project (the "Project" folder in my case), and then have all the source code that lives in trunk, tags and branches all pulled down to your hard drive. This sucks because it requires way too much stuff on your hard drive, and even worse, when you are working in a solution in Visual Studio, you won't be able to pull down "Version 2.0" and have all your project references to other projects work, because they'll all be pointing to "trunk" folders under the main folder, not just the main folder itself. What I want to do is have the root "Project/Website" folder on my hard drive, and be able to have it point to (mapped to) either tags, branches, or trunk, depending on what i'm doing, without having to screw around with fixing Visual Studio project references. Ideas?
