• Simulating a contains If-Else using RewriteCond

  - by hlissner

  Hi! I'm trying to get my head around RewriteCond, and want to rewrite any requests either to a static html page (if it exists), or to a specific index.php (so long as the requested file doesn't exist). To illustrate the logic: if HTTP_HOST is '(www\.)?mydomain.com' if file exists: "/default/static/{REQUEST_URI}.html", then rewrite .* to /default/static/{REQUEST_URI}.html else if file exists: {REQUEST_FILENAME}, then do not rewrite else rewrite .* to /default/index.php I don't seem to have much trouble doing it when I don't need to test for the HTTP_HOST. Ultimately, this one .htaccess file will be handling requests for several domains. I know I could get around this with vhosts, but I'd like to figure out how to do it this way. Here's where I am at now: RewriteCond %{HTTP_HOST} ^(www\.)?mydomain\.com$ [NC] RewriteCond /default/static/%{REQUEST_URI}.html -f RewriteRule . /default/static/%{REQUEST_URI}.html [L,NC] RewriteCond %{REQUEST_FILENAME} !-f RewriteRule . /default/index.php [L,QSA] I'm not too familiar with some of the other flags, will any of them be of use here (like chain|C, next|N or skip|S)? Thanks in advance!

• When is factory method better than simple factory and vice versa?

  - by Bruce

  Hi all Working my way through the Head First Design Patterns book. I believe I understand the simple factory and the factory method, but I'm having trouble seeing what advantages factory method brings over simple factory. If an object A uses a simple factory to create its B objects, then clients can create it like this: A a = new A(new BFactory()); whereas if an object uses a factory method, a client can create it like this: A a = new ConcreteA(); // ConcreteA contains a method for instantiating the same Bs that the BFactory above creates, with the method hardwired into the subclass of A, ConcreteA. So in the case of the simple factory, clients compose A with a B factory, whereas with the factory method, the client chooses the appropriate subclass for the types of B it wants. There really doesn't seem to be much to choose between them. Either you have to choose which BFactory you want to compose A with, or you have to choose the right subclass of A to give you the Bs. Under what circumstances is one better than the other? Thanks all!

• From Sinatra Base object. Get port of application including the base object

  - by Poul

  I have a Sinatra::Base object that I would like to include in all of my web apps. In that base class I have the configure method which is called on start-up. I would like that configure code to 'register' that service with a centralized database. The information that needs to be sent when registering is the information on how to contact this web-service... things like host and port. I then plan on having a monitoring service that will spin over all registered services and occasionally ping them to make sure they are still up and running. In the configure method I am having trouble getting the port information. The 'self.settings.port' variable doesn't seem to work in this method. a) any ideas on how to get the port? I have the host. b) is there a sinatra plug-in that already does something like this so I don't have to write it myself? :-) //in my Sinatra::Base code. lets call it register_me.rb RegisterMe < Sinatra::Base configure do //save host and port information to database end get '/check_status' //return status end //in my web service code require register_me //at this point, sinatra will initialize the RegisterMe object and call configure post ('/blah') //example of a method for this particular web service end

• PHP OOP singleton doesn't return object

  Weird trouble. I've used singleton multiple times but this particular case just doesn't want to work. Dump says that instance is null. define('ROOT', "/"); define('INC', 'includes/'); define('CLS', 'classes/'); require_once(CLS.'Core/Core.class.php'); $core = Core::getInstance(); var_dump($core->instance); $core->settings(INC.'config.php'); $core->go(); Core class class Core { static $instance; public $db; public $created = false; private function __construct() { $this->created = true; } static function getInstance() { if(!self::$instance) { self::$instance = new Core(); } else { return self::$instance; } } public function settings($path = null) { ... } public function go() { ... } } Error code Fatal error: Call to a member function settings() on a non-object in path It's possibly some stupid typo, but I don't have any errors in my editor. Thanks for the fast responses as always.

• Any useful suggestions to figure out where memory is being free'd in a Win32 process?

  - by LeopardSkinPillBoxHat

  An application I am working with is exhibiting the following behaviour: During a particular high-memory operation, the memory usage of the process under Task Manager (Mem Usage stat) reaches a peak of approximately 2.5GB (Note: A registry key has been set to allow this, as usually there is a maximum of 2GB for a process under 32-bit Windows) After the operation is complete, the process size slowly starts decreasing at a rate of 1MB per second. I am trying to figure out the easiest way to quickly determine who is freeing this memory, and where it is being free'd. I am having trouble attaching a memory profiler to my code, and I don't particularly want to override the new/delete operators to track the allocations/deallocations (IOW, I want to do this without re-compiling my code). Can anyone offer any useful suggestions of how I could do this via the Visual Studio debugger? Update I should also mention that it's a multi-threaded application, so pausing the application and analysing the call stack through the debugger is not the most desirable option. I considered freezing different threads one at a time to see if the memory stops reducing, but I'm fairly certain this will cause the application to crash.

• Horizontal histogram won't accept input after the first input

  - by vincentbelkin

  So I'm making a program which is supposed to print a horizontal histogram of the lengths of words in its input. I don't know if most of it is OK since the main problem is it won't accept any input after the first one. Oh I also put comments on the parts I'm having some trouble with, like how to print "-" multiple times in order to represent histogram. I've tried making other versions of the code but I couldn't check if I'm close to getting it because again it won't accept another input after the first input. /*Write a program to print a histogram of the lengths of words in its input. It is easy to draw the histogram with the bars horizontal*/ #include <stdio.h> #define MAX 30 #define IN 1 #define OUT 0 int main() { int a,c,i,k,state,word[MAX]; a=0; k=0; state=OUT; for(i=0;i<MAX;i++) word[i]=0; while((c=getchar())!=EOF) { if(c==' '||c=='\t'||c=='\n') state=OUT; else state=IN; while(state==IN) a++; if(state==OUT) { word[i]=a; i++; } /*This part is hard for me, I don't know how to print X multiple times!*/ if((c==getchar())&&c==EOF) { for(i=0;i<MAX;i++) { for(i=0;i<=word[i];i++) putchar('-'); putchar('\n'); } } } }

• Javascript tr click event with newly created rows

  - by yalechen

  I am very new to web development. I am currently using tablesorter jquery plugin to create a dynamic table, where the user can add and delete rows. I am having trouble with changing the background color of newly created rows upon clicking. It works fine with rows that are hard coded in html. Here is the relevant code: $(document).ready( function() { $('table.tablesorter td').click( function (event) { $(this).parent('tr').toggleClass('rowclick'); $(this).parent('tr').siblings().removeClass('rowclick'); }); } ) rowclick is a css class here: table.tablesorter tbody tr.rowclick td { background-color: #8dbdd8; } I have tried adding the following to my javascript function that adds a new row: var createClickHandler = function(newrow) { return function(event) { //alert(newrow.cells[0].childNodes[0].data); newrow.toggleClass('rowclick'); newrow.siblings().removeClass('rowclick'); }; } row.onclick = createClickHandler(row); The alert correctly displays the text in the first column of the row when I click the new row. However, my new rows do not respond to the css class. Anyone have any ideas? Thanks in advance.

• Installing django on dreamhost (help a newb out)

  - by augustfirst

  I'm trying to get django running on my dreahost account. I've been trying to sort of use two tutorials at once: the one on the dreamhost wiki and the one in the django book. I installed django using the script on the wiki page, but I ran into trouble immediately while trying to work through the django book. It says: To start the server, change into your project directory (cd mysite), if you haven’t already, and run this command: python manage.py runserver This launches the server locally, on port 8000, accessible only to connections from your own computer. Now that it’s running, visit 127.0.0.1:8000 with your Web browser. You’ll see a “Welcome to Django” page shaded in a pleasant pastel blue. It worked! Those instructions seem to assume that you're developing locally, not on a shared server. Where the heck am I supposed to look for the "Welcome to Django" page after starting the server? In my webroot? No dice. Anyway, I tried to blunder ahead through the django book to its hello world tutorial (chapter 3). But once I've edited the view file and the URLconf, I don't get a nice clean "hello world" text. Instead (as you can see) I get an "import error". Any help would be greatly appreciated.

• Ruby Alias and module_function

  - by Jesse J

  I'm trying to debug someone else's code and having trouble figuring out what's wrong. When I run rake, one of the errors I get is: 2) Error: test_math(TestRubyUnits): NoMethodError: undefined method `unit_sin' for CMath:Module /home/user/ruby-units/lib/ruby_units/math.rb:21:in `sin' This is the function that calls the method: assert_equal Math.sin(pi), Math.sin("180 deg".unit) And this is what the class looks like: module Math alias unit_sin sin def sin(n) Unit === n ? unit_sin(n.to('radian').scalar) : unit_sin(n) end alias unit_cos cos def cos(n) Unit === n ? unit_cos(n.to('radian').scalar) : unit_cos(n) end ... module_function :unit_sin module_function :sin module_function :unit_cos module_function :cos ... end (The ellipsis means "more of the same"). As far as I can see, this is valid Ruby code. Is there something I'm missing here that's causing the error, or could the error be coming from something else? Update: I'm wondering if the problem has to do with namespaces. This code is attempting to extend CMath, so perhaps the alias and/or module_function isn't actually getting into CMath, or something like that....

• Why is the exception thrown on memcpy using during copying LPBYTE to LPTSTR (clipboard)?

  - by user46503

  Hello, I have a LPBYTE array (taken from file) and I need to copy it into LPTSRT (actually into the clipboard). The trouble is copying work but unstable, sometime an exception was thrown (not always) and I don't understand why. The code is: FILE *fConnect = _wfopen(connectFilePath, _T("rb")); if (!fConnect) return; fseek(fConnect, 0, SEEK_END); lSize = ftell(fConnect); rewind(fConnect); LPBYTE lpByte = (LPBYTE) malloc(lSize); fread(lpByte, 1, lSize, fConnect); lpByte[lSize] = 0; fclose(fConnect); //Copy into clipboard BOOL openRes = OpenClipboard(NULL); if (!openRes) return; DWORD err = GetLastError(); EmptyClipboard(); HGLOBAL hText; hText = GlobalAlloc(GMEM_MOVEABLE, (lSize+ sizeof(TCHAR))); LPTSTR sMem = (TCHAR*)GlobalLock(hText); memcpy(sMem, lpByte, (lSize + sizeof(TCHAR))); The last string is the place where the exception is thrown. Thanks a lot

• Checking if a console application is still running using the Process class

  - by Ced

  I'm making an application that will monitor the state of another process and restart it when it stops responding, exits, or throws an error. However, I'm having trouble to make it reliably check if the process (Being a C++ Console window) has stopped responding. My code looks like this: public void monitorserver() { while (true) { server.StartInfo = new ProcessStartInfo(textbox_srcdsexe.Text, startstring); server.Start(); log("server started"); log("Monitor started."); while (server.Responding) { if (server.HasExited) { log("server exitted, Restarting."); break; } log("server is running: " + server.Responding.ToString()); Thread.Sleep(1000); } log("Server stopped responding, terminating.."); try { server.Kill(); } catch (Exception) { } } } The application I'm monitoring is Valve's Source Dedicated Server, running Garry's Mod, and I'm over stressing the physics engine to simulate it stopping responding. However, this never triggers the process class recognizing it as 'stopped responding'. I know there are ways to directly query the source server using their own protocol, but i'd like to keep it simple and universal (So that i can maybe use it for different applications in the future). Any help appreciated

• MSBUILD batch targets

The output looks like this: Deployment to server done here. Deploying to server: Notice there is no server name, nor is done more than once. There are 2 lines in DenormDevServers.txt

• In Powerpoint 2007, how can I position a Callout's Tail programatically?

  - by Rorschach

  I'm looking at the XML and this is what it has for the Callout object's coordinates and geometry: <p:spPr> <a:xfrm> <a:off x="2819400" y="5181600"/> // X,Y Position of Callout Box <a:ext cx="609600" cy="457200"/> // Width,Height of Callout Box </a:xfrm> <a:prstGeom prst="wedgeRectCallout"> <a:avLst> <a:gd name="adj1" fmla="val 257853"/> // X Position Of Tail <a:gd name="adj2" fmla="val -532360"/> // Y Position of Tail </a:avLst> </a:prstGeom> <a:solidFill> <a:schemeClr val="accent1"> <a:alpha val="50000"/> </a:schemeClr> </a:solidFill> </p:spPr> What I'm having trouble with is the formula for telling it to place the tail at a particular coordinate on the slide. I've tried this to calculate it, but it does not work correctly. //This gives me the distance between the Coordinate and the Center of the Callout. DistanceX = Coordinate.X - (Callout.X + Callout.X_Ext)/2 DistanceY = Coordinate.Y - (Callout.Y + Callout.Y_Ext)/2 But, the geometric value is not the distance between the two points. Anybody know what the formula is for calculating this?

• How do I build a filtered_streambuf based on basic_streambuf?

  - by swestrup

  I have a project that requires me to insert a filter into a stream so that outgoing data will be modified according to the filter. After some research, it seems that what I want to do is create a filtered_streambuf like this: template <class StreamBuf class filtered_streambuf: public StreamBuf { ... } And then insert a filtered_streambuf<> into whichever stream I need to be filtered. My problem is that I don't know what invariants I need to maintain while filtering a stream, in order to ensure that Derived classes can work as expected. In particular, I may find I have filtered_streambufs built over other filtered_streambufs. All the various stream inserters, extractors and manipulators work as expected. The trouble is that I just can't seem to work out what the minimal interface is that I need to supply in order to guarantee that an iostream will have what it needs to work correctly. In particular, do I need to fake the movement of the protected pointer variables, or not? Do I need a fake data buffer, or not? Can I just override the public functions, rewriting them in terms of the base streambuf, or is that too simplistic?

• Android: FragmentAdapter and pageview do not update the view

  - by user1240937

  My trouble is: when i get new data, my viewpager that use my custom adapter do not update view. I discovered that many programmer got same bug, so i tried a lot of suggestion but no way works for me. So tired. One more time, read my source and help me understand why i fail with updating view pleaseee! Here is my FragmentAdapter: private class SwipeyTabsPagerAdapter extends FragmentPagerAdapter implements SwipeyTabsAdapter { private final Context mContext; private String[] datas; public SwipeyTabsPagerAdapter(Context context, FragmentManager fm, String[] ds) { super(fm); this.mContext = context; datas=ds; } @Override public int getItemPosition(Object object) { return POSITION_NONE; } @Override public Fragment getItem(int position) { Log.e("new item:", datas[position]); return SwipeyTabFragment.newInstance(datas[position]); } @Override public int getCount() { return datas.length; } public TextView getTab(final int position, SwipeyTabs root) { TextView view = (TextView) LayoutInflater.from(mContext).inflate( R.layout.swipey_tab_indicator, root, false); view.setText(datas[position]); view.setOnClickListener(new OnClickListener() { public void onClick(View v) { mViewPager.setCurrentItem(position); } }); return view; } } and here is where i set adapter: SwipeyTabsPagerAdapter adapter = new SwipeyTabsPagerAdapter(getApplicationContext(), getSupportFragmentManager(),dicts); mViewPager.setAdapter(adapter); mTabs.setAdapter(adapter); mViewPager.getAdapter().notifyDataSetChanged(); By logcat, can see clearly that: only first time, newItem be processed, so view can not be update.

• How would I go about sharing variables in a C++ class with Lua?

  - by Nicholas Flynt

  I'm fairly new to Lua, I've been working on trying to implement Lua scripting for logic in a Game Engine I'm putting together. I've had no trouble so far getting Lua up and running through the engine, and I'm able to call Lua functions from C and C functions from Lua. The way the engine works now, each Object class contains a set of variables that the engine can quickly iterate over to draw or process for physics. While game objects all need to access and manipulate these variables in order for the Game Engine itself to see any changes, they are free to create their own variables, a Lua is exceedingly flexible about this so I don't forsee any issues. Anyway, currently the Game Engine side of things are sitting in C land, and I really want them to stay there for performance reasons. So in an ideal world, when spawning a new game object, I'd need to be able to give Lua read/write access to this standard set of variables as part of the Lua object's base class, which its game logic could then proceed to run wild with. So far, I'm keeping two separate tables of objects in place-- Lua spawns a new game object which adds itself to a numerically indexed global table of objects, and then proceeds to call a C++ function, which creates a new GameObject class and registers the Lua index (an int) with the class. So far so good, C++ functions can now see the Lua object and easily perform operations or call functions in Lua land using dostring. What I need to do now is take the C++ variables, part of the GameObject class, and expose them to Lua, and this is where google is failing me. I've encountered a very nice method here which details the process using tags, but I've read that this method is deprecated in favor of metatables. What is the ideal way to accomplish this? Is it worth the hassle of learning how to pass class definitions around using libBind or some equivalent method, or is there a simple way I can just register each variable (once, at spawn time) with the global lua object? What's the "current" best way to do this, as of Lua 5.1.4?

• XForms relation of 'constraint' and 'required' properties

  - by Danny

  As a reference, the most similar question already asked is: http://stackoverflow.com/questions/8667849/making-xforms-enforce-the-constraint-and-type-model-item-properties-only-when-fi The difference is that I cannot use the relevant properties since I do want the field to be visible and accessible. I'm attempting to make a XForms form that has the following properties: It displays a text field named 'information'. (for the example) This field must not be required, since it may not be necessary to enter data. (Or this data will be entered at a later time.) However, if data is entered in this field, it must adhere to the specified constraint. I cannot mark the field as not relevant since this would hide the field and some data may need to be entered in it. The trouble now is that even though the field has no data in it, the constraint is still enforced (i.e. even though it is not marked as 'required'). I have taken a look at the XForms 1.1 specification, however it does not seem to describe how the properties 'required' and 'constraint' should interact. The only option I see, is to add a part to the constraint such that an empty value is allowed. e.g.: . = '' or <actual-constraint However, I don't like this. It feels like a workaround to add this to every such field. Is there any other way to express that non-required fields should not need to match the constraint for that field? (Am I missing something?)

• Populating an array into a TableView - Thanks in advance.

  - by tssav

  Hello Developers, View not being populated with the array. I would really appreciate if I could get some help. Thanks!! In a tableView I have the following: NSDictionary *cat = [category objectAtIndex:indexPath.row]; cell.textLabel.text = [cat valueForKey:@"reference"]; This populates the tableView with the content of the array from an XML file. There is another array “data” that prints out the content to the debug console and I want to populate another view with this content. But I am having lot of trouble populating the next view with the data array. NSLog(@"cellForRowAtIndexPath-- Reference:%@: Verse:%@", [cat valueForKey:@"reference"], [cat valueForKey:@"data"]); The didSelectRowAtIndexPath method looks like this: Verse *vvc = [[Verse alloc] initWithNibName:@"VerseView" bundle:nil]; vvc.verses = [[category objectAtIndex:indexPath.row] valueForKey:@"verse"]; [self.navigationController pushViewController:vvc animated:YES]; [vvc release]; [tableView deselectRowAtIndexPath:indexPath animated:YES]; In the cellForRowAtIndexPath of the next view I have the following: NSDictionary *cat = [verses objectAtIndex:indexPath.row]; cell.textLabel.text = [cat valueForKey:@"data"]; What I would like is to have the “data” in a textView. I don’t know what’s wrong. Any help would be appreciated!

• Trying to override onbeforeunload in first step of form wizard

  - by Dirty Bird Design

  This pertains to a form wizard with 5 steps, I don't want the user to hit back and lose form data in any step 2-4. I have added a flag for the submit function and need to add this one for the first step. If they get there by accident and try and leave I dont want the cofirm dialog popping up. <script type="text/javascript"> $(document).ready(function(){ var action_is_post = false; $("form").submit(function () { action_is_post = true; }); //this is the trouble spot. on the first step the "navigation" of the form has a class of current (on step one = current) $(this).ready(function () { if ($("#stepDesc0").is(".current")) { action_is_post = true; } ); window.onbeforeunload = confirmExit; function confirmExit() { if (!action_is_post) return 'Using the browsers back, refresh or close button will cause you to lose all form data. Please use the Next and Back buttons on the form.'; } }); </script>

• PHP Ampersand in String

  - by John

  Hello. I'm having a bit of a problem. I am trying to create an IRC bot, which has an ampersand in its password. However, I'm having trouble putting the ampersand in a string. For example... <?php $var = "g&abc123"; echo $var; ?> I believe this should print g&abc123. However it's printing g. I have tried this as well: <?php $arr = array("key" => "g&abc123"); print_r($arr); ?> This prints it correctly with the g&abc123, however when I say echo $arr['key']; it prints g again. Any help would be appreciated. I'm running PHP5.3.1. EDIT: Also, I just noticed that if I use g&abc123&abc123 it prints g&abc123. Any suggestions?

• JSP:Include not rendering the page correctly

  - by sreekanth

  am having trouble with including a jsp page with tag. This is what is happening. I making changes to a portlet application running on Websphere 7 server. This is the hierarchy of the jsp pages. blankPage.jsp --bookingViewTabs.jsp -- availableRooms.jsp meaning blankPage is included in bookingViewTabs which is inturn included in availableRooms.jsp I have 2 problems with this. (1). The blankPage.jsp does not render correctly on the screen. It gets cutoff (2). The other is in blankPage.jsp there is a form called "guestProfileSearchResultsFormId". this form has several hidden fields for data. example, "guestId" which is a child of that form and can be accessed formname.fieldname, but when i include that page into another jsp as the first include(there are several includes on the page) under the another form tag, the form field is not being rendered as a child of the form, but as a sibling of the form. If i change the order and include some other page and include this, it is working as it is supposed to have. meaning with children intact. I don't understand this behavior. I HAVE ATTACHED A GIF IMAGE OF WHAT I SEE ON THE BROWSER Any help is greatly appreciated. Thanks in advance

• Schema for element with Attributes and Child nodes

  - by Matthew

  I am trying to write xsd type schema for an element that has a custom type to include addition attributes to extend a base type. I am running into trouble getting the syntax right. <xs:element name="graphs"> <xs:complexType> <xs:sequence> <xs:element name="graph" minOccurs="1" maxOccurs="unbounded" type="graphType"> <!-- child elements --> </xs:element> </xs:sequence> </xs:complexType> </xs:element> <xs:complexType name="graphType"> <xs:simpleContent> <xs:extension base="xs:string"> <xs:attribute name="title" type="xs:string"/> <xs:attribute name="type" type="xs:string"/> </xs:extension> </xs:simpleContent> </xs:complexType> I thought this would be something very common, but having read many tuts and forums, I cant seem to find an answer that works for me.
