• Can I switch the Visual C++ runtime to another heap?

  - by sharptooth

  My program uses a third party dynamic link library that has huge memory leaks inside. Both my program and the library are Visual C++ native code. Both link to the Visual C++ runtime dynamically. I'd like to force the library into another heap so that all allocations that are done through the Visual C++ runtime while the library code is running are done on that heap. I can call HeapCreate() and later HeapDestroy(). If I somehow ensure that all allocations are done in the new heap I don't care of the leaks anymore - they all go when I destroy the second heap. Is it possible to force the Visual C++ runtime to make all allocations on a specified heap?

• Getting HTMLUnknownElement with jQuery.find() and an XML Document

  - by Tom

  I'm attempting to load up an XML document (specifically an RSS feed) via an Ajax request, parse it, and insert some information based on said feed into my page. The code works fine in Firefox, Opera, Chrome, and Safari, but not IE7. Go figure. After doing some initial debugging, I've found that the XML string is being retrieved via the request, and the specific node type I'm getting when trying to parse nodes out of the document is HTMLUnknownElement. Here's the relevant code: $.get('feed.php', function(oXmlDoc) { var titles = $(oXmlDoc).find('title'); var dates = $(oXmlDoc).find('pubDate'); for(var i = 0; i < 5; i++) { parseNodes(titles[i].firstChild.nodeValue, dates[i].firstChild.nodeValue)); } }); The parseNodes function is never actually being hit because IE cannot access firstChild and, consequently, nodeValue. Thanks in advance for any ideas and/or suggestions on how to address this.

• std::out_of_range error?

  - by vette982

  I'm dealing with a file with a linked list of lines with each node looking like this: struct TextLine{ //The actual text string text; //The line number of the document int line_num; //A pointer to the next line TextLine * next; }; and I'm writing a function that adds spaces at the beginning of the lines found in the variable text, by calling functions like linelist_ptr->text.insert(0,1,'\t'); The program compiles, but when I run it I get this error: terminate called after throwing an instance of 'std::out_of_range' what(): basic_string::at Aborted Any ideas?

• Display indented XML code within a HTML page

  - by Efrain

  I have a programmatically created HTML document on which I would like to show some XML-code, fully formatted with line breaks and tabulators. That is, it should look like if you drag an xml file without a xml-stylesheet directly onto your browser (most browsers do some kind of xml-rendering with some default style sheet). Now, I can of course escape all the characters (like <>, tab and newline) and do the indenting myself (using css styles, for example), but I was wondering whether I couldn't re-use some 'default' xml-stylesheet from somewhere. Preferrably also one that has some javascript node-folding, too. Do you know such a stylesheet/xslt? Or would you suggest another way to achieve this? I'm using C#. PS: I tried to use the XmlNotepad.DefaultSS.xslt from Microsoft's XmlNotepad, but I couldn't really get that working. :T

• Android browser javascript events when minimised

  - by Sirber

  I'm building a webapp for Android smartphones that runs with the OS internet browser. the main interface is to input datas. the data is added to a queue (android 1.5: gears, android 2.x: html5). Each 5 minutes (using setTimeout), the script looks if an internet connection is active, and if so, sends all the queue to the server. If the phone is plugged on the wall and the webpage is ontop, the timeout works. if the browser is minimized or another application runs on top of it, the timeout doesn't work. if the phone is in sleep mode it doesn't work either. can only native apps runs in background?

• Structure of Astar (A*) graph search data in C#

  - by Shawn Mclean

  How do you structure you graphs/nodes in a graph search class? I'm basically creating a NavMesh and need to generate the nodes from 1 polygon to the other. The edge that joins both polygons will be the node. I'll then run A* on these Nodes to calculate the shortest path. I just need to know how to structure my classes and their properties? I know for sure I wont need to create a fully blown undirected graph with nodes and edges.

• How to organize product catalog site in Drupal 6?

  - by user319366

  Hello there, please advice me how to organize product catalog site with such structure (this is pages which should be in site map): - Home page - About Us -- Team -- Contacts - Products -- Category --- Product ---- Overview ---- Photo gallery ---- Variants -- Category --- Subcategory --- Product ---- Overview ---- Photo gallery ---- Variants I know that i can use Page nodes for general pages like About page. And i can prepare Product node with CCK with needed fields. Then i can use taxonomy vocabulary for product categories/subcategories. Is this a right way to do such functionality? Or better to use just child/parent nodes? And how i can show subpages menu on product page? How i can organize menus? I need one menu with primary links, second menu below it, for secondary links (except Products catalog) and sidebar menu for Products catalog. Please advice. May be this is easy questions, but i just learning Drupal (but i have experience with other CMS). Thanks a lot.

• Why are some strings displayed as garbage when I scroll my read-only multiline Win32 edit control ve

  - by sharptooth

  In my native C+ Win32 GUI application I have a property sheet with two property pages. One of the property pages contains an edit box: EDITTEXT IDC_EDIT_ID,x,y,width,height,ES_MULTILINE | ES_READONLY | NOT WS_BORDER | WS_VSCROLL | WS_HSCROLL | NOT WS_TABSTOP,WS_EX_STATICEDGE I set a multiline text to this edit box. The text has more lines than the edit can fit, so some of the text is clipped and a vertical scroll bar appears. When I scroll up with the mouse the lines that come "from under clip area" are drawn as garbage - it looks like first one line is drawn, then some other line is drawn on the same place without first painting the background. The lines that just move up - ones that were visible before scrolling and remain visible after scrolling are displayed allright. What's the reason and workaround for this behavior?

• Tomcat thread waiting on and locking the same resource

  - by Adam Matan

  Consider the following Java\Tomcat thread dump: "http-0.0.0.0-4080-4" daemon prio=10 tid=0x0000000019a2b000 nid=0x360e in Object.wait() [0x0000000040b71000] java.lang.Thread.State: WAITING (on object monitor) at java.lang.Object.wait(Native Method) - waiting on <0x00002ab5565fe358> (a org.apache.tomcat.util.net.JIoEndpoint$Worker) at java.lang.Object.wait(Object.java:485) at org.apache.tomcat.util.net.JIoEndpoint$Worker.await(JIoEndpoint.java:458) - locked <0x00002ab5565fe358> (a org.apache.tomcat.util.net.JIoEndpoint$Worker) at org.apache.tomcat.util.net.JIoEndpoint$Worker.run(JIoEndpoint.java:484) at java.lang.Thread.run(Thread.java:662) Is this a deadlock? It seems that the same resource (0x00002ab5565fe358) is both locked and waited on - what does it mean?

• How do I create a create and execute an SQL command using OleDB directly?

  - by Pagis

  I want to use the OleDB interfaces directly to open a connection to a DB, create a command and executing it (for example using the ICommandText interface). The main thing I can't find is how to create the connection and the command object and how to connect the object that implements the ICommandText to the connection. In ADO I would just use the ActiveConnection property but I want to do this directly on the OleDB interfaces. Also, if anyone can recommend a tutorial to OleDB, ether online or a book, free or not that would be great (but a tutorial and not just a reference / API) I'm using C++ but any native code would be fine.

• Blackberry browser problem

  - by nhd

  Hi all, I have one site to test, when I run it with my BrowserFieldDemo (in JDE sample)m just display text site, but with the same link, run on Blackberry native browser, it displays properly, and have Zoom in function to zoom. I think the problem here is the size of my site, it's too large. I've tried some different sites and see that the result is same on two browsers, but with this test site, it's unexpected result. Anyone can suggest some solutions for me to fix it? Or explain for me how Blackberry browser can know to resize web page automatically (when it loads the large web page). Thank for any help,

• Azure Service Bus Scalability

  - by phebbar

  I am trying to understand how can I make Azure Service Bus Topic to be scaleable to handle 10,000 requests/second from more than 50 different clients. I found this article at Microsoft - http://msdn.microsoft.com/en-us/library/windowsazure/hh528527.aspx. This provides lot of good input to scale azure service bus like creating multiple message factories, sending and receiving asynchronously, doing batch send/receive. But all these input are from the publisher and subscriber client perspective. What if the node running the Topic can not handle the huge number of transactions? How do I monitor that? How do I have the Topic running on multiple nodes? Any input on that would be helpful. Also wondering if any one has done any capacity testing with Topic/Queue and I am eager to see those results... Thanks, Prasanna

• How to Create a Virtual Windows Drive

  - by HyLian

  Hello, I'm trying to create a Windows Virtual Drive ( like c:\ ) to map a remote storage. The main purpose is to do it in a clear way to the user. Therefore the user wouldn't know that he is writing/reading from another site. I was searching for available products, and i find that FUSE is not an option in Windows and WebDAV maps directly the drive, and i would like to build a middle layer between windows and remote storage to implement some kind of services. Another alternatives exists, such as Dokan, that is very expensive, and System.IO.IsolatedStorage Namespace, that doesn't seem to explicity create a new Windows Drive. Probably pismo ( http://www.pismotechnic.com/ ) is the thing that mostly matches my requirements but I would know if there is another alternative, including some Windows ( C++ or .NET ) native API to do that. Thanks for reading :)

• Seek a jQuery-based inplace HTML editor

  I just stepped over to http://plugins.jquery.com/search/node/editor - lots and lots of choices - and if to judge by the dates, many new offerings. I'm hoping someone can help me narrow down the field according to these priorities... Stability & Well-formed XHTML (might argue against some of the most recent unless they are revisions with a clear track-record) Inplace editing Good AJAX integration For internal / admin / CMS usage so it can be as bloated as it needs to be long as it's easy to implement the basics: bold ital indents lists No need for tables but dropdowns that show relevent CSS selectors would be nice. thnkx

• Upload file from client machine to server - prepopulate file picker path?

  - by user246114

  Hi, I'd like to upload a file from a client machine to my server. The user would have to specify the file to upload as I understand it, using a form that looks like: <input type="file" name="datafile" size="40"> This pops up a native file picker, which is great. The problem I'm having is that it's a real pain (for most users) to go looking around their machine for the file I'm interested in. Is there a way I can initialize the file picker with a path to make it more convenient for the user? Like I know some users will be on a windows machine, so I could prepopulate the picker by already sending them to the My Documents folder for example. I don't see how this is possible, just wondering if something like that exists, Thank you

• Why does C++ linking use virtually no CPU? (updated)

  - by John

  On a native C++ project, linking right now can take a minute or two, yet during this time CPU drops from 100% during compilation to virtually zero. Does this mean linking is primarily a disk activity? If so, is this the main area an SSD would make big changes? But, why aren't all my OBJ files (or as many as possible) kept in RAM after compilation to avoid this? With 4Gb of RAM I should be able to save a lot of disk access and make it CPU-bound again, no? update: so the obvious follow-up is, can VC++ compiler and linker talk together better to streamline things and keep OBJ files in memory, similar to how Delphi does?

• concurrent doubly-linked list (1 writer, n-readers)

  - by Arne

  Hi guys, I am back in the field of programming for my Diploma-thesis now and stumbled over the following issue: I need to implement a thread-safe doubly-linked list for one thread writing the list at any position (delete, insert, mutate node data) and one to many threads traversing and reading the list. I am well aware that mutexes can be used to serialize access to the list, still I presume that a naive lock around any write operation will be less than optimal. I am wondering whether there are better variants. (I am well aware that 'optimal' has not much of a practical meaning as long as no exact measure/profiling are available but this is an academic thesis after all..) I am very gratefull for code-samples as well as references to academic granted these have at least a tiny bit of practical relevance. Thanks at lot
