• Having trouble with fadeIn and fadeOut in IE8 with jQuery

  - by TheDelChop

  Guys, Here is my site: http://www.dreamweddinggroup.com/redesign and I'm having a hell of a tough time figuring out why in gods name my fadeIn, fadeOut and corner() functions won't work in IE8. They were working for a time, but now they have broken and I can't for the life of me figure it out. Can anybody see anything that would cause the problem here? To see what I'm talking about, if you were to click on the "About Us" link at the bottom of the page, you should see the text fade in. Then if you were to click on "Why Dream Wedding Group", the "About Us" text should fade out, and when it fades back in, you would see the new text. Thank you, Joe

• A good web 'desktop' JavaScript, CSS, or both, library that likes ASP.NET Web Forms

  - by ProfK

  I've come across, in passing, several suites of functions, widgets, frameworks, etc. that seek to produce a desktop like experience on the web. Most are JavaScript and CSS tools that handle web content on an emulation of the desktop-paradigmed UI, e.g. TreeView + Content == Explorer. Is there such a library nicely compatible with ASP.NET Forms without weeks of grief? I'll also settle for something similar, but instead of native ASP.NET, a library for any of the open source CMS products for ASP.NET. (Umbraco is at the top of my list, followed by mojoPortal. I aspire to the level of coding their creators easily demonstrate in the product. [PS, I don't want a 'desktop' ux per se, just light and simple dynamic layout for drag 'n drop, dock windows, a dock bar?.. and other fancy magic.

• iPhone SDK Smaller CAF files: lower recording quality with Audio Queues?

  - by Nick

  In my iPhone app I have voice recording functionality the utilizes Audio Queue voice recording functions of the SDK. I'm saving directly to CAF format and using the following settings for the AudioStreamBasicDescription reference: audioFormat.mFormatID = kAudioFormatLinearPCM; I can see that there are other format ids I could use like: kAudioFormatLinearPCM kAudioFormatAppleLossless kAudioFormatAppleIMA4 kAudioFormatiLBC kAudioFormatULaw kAudioFormatALaw My knowledge of sound formats is very limited so my question is... which of these should I use to create the lowest compressed audio recording files? Plus, are there other settings I should apply to lower the quality and filesize even further?

• Using a C#.net DLL in Node.js / serverside javascript

  - by Dve

  I have spent a while playing with node.js and exploring related frameworks such as express and geddy... and I am very impressed, especially with the WebSockets implementation in socket.io. I have a pet project that is an online game, the entire game engine is written in C# and I would like to know if there is anyway I can call the functions of this existing dll from a solution built using node.js, socket.io, express etc? The game engine itself is pretty complete; tested and robust. I am hoping there is some neat way of exposing its functionality without to much overhead. Thanks

• Google Closure Library - Adding non-TreeNode children to a TreeNode

  - by Andreas Jansson

  Hi, I'm using the Google Closure Library and goog.ui.tree in particular to build a tree structure GUI component. It works pretty well out of the box, but I'd like to add a few extra controls to each of the leaves (goog.ui.Checkboxes in particular). The problem is that Component.addChild has been overridden in BaseNode so that each added child is treated as a child tree node as opposed to a child component. In effect plenty of errors are thrown if you try to add anything else than an actual tree node as a child, as these children are traversed and BaseNode-specific functions are called on them. I must admit I'm quite a Closure newb, but I reckon there must be some workaround for this, right? Essentially all I want to do is have a bunch of checkboxes appear next to each leaf in my tree. Thanks, Andreas

• Regex for circular replacement

  - by polygenelubricants

  How would you use regex to write functions to do the following: Replace lowercase 'a' with uppercase and vice versa Where words are separated by whitespaces and > and < are special markers, replace >word with word< and vice versa Replace postincrement (i++;) with preincrement (++i;) and vice versa. Variable names are [a-z]+. Input is just a bunch of these statements. Bonus: also do decrement. Also interested in solutions in other flavors. Note: this is NOT a homework question. See also my previous explorations of regex: Regex split into overlapping strings (Alan Moore's answer is especially instructive) Can you use zero-width matching regex in String split? (my solution exploits a known Java regex bug with regards to non-obvious length lookbehind!)

• Integrate Cppcheck with Emacs

  - by N.N.

  Is it possible to integrate Cppcheck with Emacs in a more sophisticated way than simply calling the shell command on the current buffer? I would like Emacs to be able to parse Cppcheck's messages and treat them as messages from a compiler (similar to how compile works), such as using C-x ` to visit the targets of Cppcheck's messages. Here is some example output Cppcheck: $ cppcheck --enable=all test.cpp Checking test.cpp... [test.cpp:4]: (error) Possible null pointer dereference: p - otherwise it is redundant to check if p is null at line 5 [test.cpp:38]: (style) The scope of the variable 'i' can be reduced [test.cpp:38]: (style) Variable 'i' is assigned a value that is never used [test.cpp:23]: (error) Possible null pointer dereference: p [test.cpp:33]: (error) Possible null pointer dereference: p Checking usage of global functions.. [test.cpp:36]: (style) The function 'f' is never used [test.cpp:1]: (style) The function 'f1' is never used [test.cpp:9]: (style) The function 'f2' is never used [test.cpp:26]: (style) The function 'f3' is never used

• Mutating PDF editable fields programatically

  - by Chris

  Out of tons of questions and answers here about manipulating PDF's with PHP, but none of them seem to fit my requirement. Programmatically, I want to be able to update the content of editable fields. Preferably with PHP. If it matters, the PDF files will be initially hand crafted (as sort of 'template' files that will be copied and filled in over and over again). The list of PDF_* functions on php.net doesn't give me anything that looks (directly) promising. Is this possible with PHP? How?

• R strsplit and vectorization

  - by James

  When creating functions that use strsplit, vector inputs do not behave as desired, and sapply needs to be used. This is due to the list output that strsplit produces. Is there a way to vectorize the process - that is, the function produces the correct element in the list for each of the elements of the input? For example, to count the lengths of words in a character vector: words <- c("a","quick","brown","fox") > length(strsplit(words,"")) [1] 4 # The number of words (length of the list) > length(strsplit(words,"")[[1]]) [1] 1 # The length of the first word only > sapply(words,function (x) length(strsplit(x,"")[[1]])) a quick brown fox 1 5 5 3 # Success, but potentially very slow Ideally, something like length(strsplit(words,"")[[.]]) where . is interpreted as the being the relevant part of the input vector.

• Using DockPanel Suite's XML saving with My.Settings

  - by Cyclone

  In vb.net, how can I use SaveAsXML and LoadFromXML (DockPanel Suite functions) with My.Settings? I know there is a way to save it to a stream, but I don't know enough about System.IO to do this. DockPanel Suite: http://sourceforge.net/projects/dockpanelsuite/ I would very much prefer to store configuration using My.Settings instead of as an XML file. Thanks for the help! EDIT: Since the only person to answer so far has since deleted their answer, I feel I should explain further: Those two methods can both accept a stream object, but I have not used System.IO enough to know how to properly initialize a stream, let alone get a string out of a stream. EDIT: Googling has gotten me nowhere. EDIT: Still waiting for this. I've tried everything...

• It is possible to override a plugin's Controller from another plugin?

  - by fabschu

  I'm developing a plugin (MyPlugin) which combines some security functions to use it as a standard plugin for my next Grails application. It integrates the Spring-Security-Core and Spring-Security-UI plugins, and by its installation all dependencies should be installed automatically by adding the dependencies in the BuildConfig like: plugins { compile: ...} So far everything works fine, but in MyPlugin I'm changing the behaviour of the Spring-Security-UI plugin (password encoding in User Domain), by overwriting the UserController. Executing MyPlugin leads to the expected behaviour and new Users are created using the correct Controller. However, when installing MyPlugin in another Grails application, this behaviour fails and the original UserController of the Spring-Security-Ui plugin is used. I tried to solve this by configuring the dependsOn and loadAfter properties in the GrailsPlugin file, but without any success. Is it possible to fix this? Or is it only possible to overwrite behaviour/controllers in the main application?

• odd problem with jni interacting with dll's - not sure why a change to gc ergonomics fixes it

  - by jim hale

  We were having a problem with our Tomcat jvm blowing up and giving us an hs_* dump at random times but always in the same spot, that wasn't very informative other than saying we had an EXCEPTION_ACCESS_VIOLATION Commenting out various parts of the java that called particular jni functions just made it blow consistently in another spot. By changing our jvm options from: set PAF_OPTS=-Xms1024m -Xmx32000m -server -XX:+UseParallelGC -XX:+UseParallelOldGC -XX:+DisableExplicitGC -XX:+UseCompressedOops -Djava.library.path="%CATALINA_HOME%"\jni -Dcom.sun.management.jmxremote TO set PAF_OPTS=-Xms1024m -Xmx32000m -server -XX:+DisableExplicitGC -XX:+UseCompressedOops -Djava.library.path="%CATALINA_HOME%"\jni -Dcom.sun.management.jmxremote The problem went away. The solution does not give me a warm and fuzzy however and am wondering anyone might understand what's going on under the covers here. Environment: jdk1.6, 64 bit OS and Java, Tomcat, Windows

• onload Event in embedded SVG not calling function in attached script. Scope Issue?

  - by Nick

  Hi So I've got an XHTML page with a script - not inline > <script type="text/javascript" > src="../global/js/scripts.js"></script> and an embedded (I tried embed and object, same behavior) SVG document with a onload="CheckIfLoaded(evt)" attribute. The problem is firefox doesn't call the CheckIfLoaded() function in scripts.js. Firebug gives me "CheckIfLoaded() is not defined" with no reference to any line numbers. I can't find any information regarding the scope of javascript functions with respect to embedded content. Curiously, it works fine in IE. I could of course add a reference to the script into the SVG file as well but I believe that will result in the client downloading the scripts file twice and in addition I have 1000+ svg files and I'd really rather not add one line to all of them, although I suppose I could write a batch file or whatever if I have to. Any one know more about this? Thanks, Nick

• Building an XML editor in java and RichFaces

  - by Mark Lewis

  Hello I'm building an XML editor using the above technologies. In essence, I want to read in a whole XML file to a java object, and refer using this object to each element in the XML node tree (grouped into entries) to display the content locked, have separate padlocks for the user to click to 'unlock' an entry allow overwriting of the data, and to submit this entry. 'Add entry', 'Duplicate entry', 'Delete entry' are also functions I'd like to add. I already use dom4j and XPath to access areas of the XML file so some of the work in theory is already done. Given the above, I was going to use these two together with inplaceInputs to allow the user to edit the XML and JSF validators to check the data coming in. Is this the best way to approach this problem, or is there a more straightforward route than XPathing a whole record? I started looking at jaxb but I'm new at java and jsf but I've got the feeling I won't be by the end.. Thanks

• CUDA: How to reuse kernels in multiple files (for unit testing)

  - by zenna

  How can I go about reusing the same kernel without getting fatal linking errors due to defining the symbol multiple times In Visual Studio I get "fatal error LNK1169: one or more multiply defined symbols found" My current structure is as follows: Interface.h has an extern interface to a C function: myCfunction() (ala the C++ integration SDK example) Kernel.cu contains the actual __global__ kernels and is NOT included in the build: __global__ my_kernel() Wrapper.cu inlcudes Kernel.cu and Interface.h and calls my_kernel<<<...>>> This all works fine. But if I add another C function in another file which also includes Kernel.cu and uses those kernels, I get the errors. So how can I reuse the kernels in Kernel.cu among many C functions in different files. The purpose of this by the way is unit testing, and integrating my kernels with CPP unit, if there is no way to reuse kernels (there must be!) then other suggestions for unit testing kernels within my existing CPP unit framework would be appreciate. Thanks Zenna

• Traversing Scheme function as a list

  - by csl

  Isn't it possible to treat functions in Scheme as any other list? Basically, what I want do to is something like this: (define (foo) "hello") (cdr foo) ; or similar, should return the list ((foo) "hello") I've found a similar discussion about this, and I feel a bit disappointed if this is not possible with Scheme. If so, why is this impossible? Is it possible in other lisps? EDIT: Changed (cdr 'foo) to (cdr foo) -- it was misleading. I'm asking, why can't I access a function as a list?

• Tutorial on Using OpenSSL with pthreads

  - by Sadeq Dousti

  OpenSSL documents state that it can safely be used in multi-threaded applications provided that at least two callback functions are set, locking_function and threadid_func.... I've written programs which use OpenSSL API. Moreover, I know how to use pthreads. However, the OpenSSL documents are written in the form of a manual, and I can't see a step-by-step guide on what I have to do when using OpenSSL in a multi-threaded app. Is there a tutorial on using OpenSSL with pthreads? (I searched the web, but no satisfactory result appeared.) PS: I'm working in Debian Lenny & Ubuntu Lucid/Maverick. PS2: OpenSSL includes a sample, but it's far too complicated to start with.

• Top level window on X Window System

  - by La Chamelle

  Hello, i want to print on the screen the informations about Top level windows under Linux. I use the xlib functions. I successfully recurse from the root window to print all the informations about all the element on display. But i need only the Top-Level window. I don't find any good way to filter. From wikipedia : The top-level windows are exactly the direct subwindows of the root window. With that definition , I have some windows like: gnome-session, seahorse-daemon,notify-osd or icons, on my list and i don't want them. I also find a function : XmuClientWindow, but i don't understand it's goal. Thanks to help me.

• How to map old paths to Drupal paths

  - by kidrobot

  I'm converting a Wordpress blog to Drupal and need to map the WP paths to the new Drupal ones. What's the best practice for doing this? There are only around a hundred pages to map. I've been experimenting with the URL Alter module, which provides an alternative to messing with custom_url_rewrite functions settings.php but keep getting 404. Waiting to hear back from the module maintainer if this is what the module is intended for. In the meantime I am wondering how others do this? Should I be using .htaccess?

• Is .NET support for Win32 Code Interop?

  - by Usman

  Hello, I need to InterOp Win32 code (unmanaged Win32 DLL's and Exe) completely with .NET. I need to call Win32 unmanaged code(DLL exported functions) at runtime i.e (knowing the types of data types in Win32 signatures and need to pass data according to that type at runtime). This is 100% possible in case of COM. You can convert COM unmanaged code to managed assemblies using tlbimp.exe and use now reflection API to work with those managed types(actual were unmanaged types now converted managed using tlbimp). But same functionality I need to get in terms of Win32(i.e) in .NET framework. How?? I know MS provided Export table reading API ..but I couldn't find exact API for InterOp of Win32 unmanaged code Regards

• Compile OpenSSL from source using Xilinx EDK

  - by Asanka

  I want to use openSSL functions in my xilinx C++ project. So i downloaded the source and tried to compile using the makefile. But unfortunately the linux box I was provided did not contained the required software (perl5, make, etc) to compile the source using makefile. So as the second option i tried to compile the source as a shared library. So i made a new project using existing openSSL source. But all the attempts were failed since it gave lots of errors including missing headers, unknown defines etc. If someone knows how to compile openssl as a shared library using Xilinx toolchains please help me. It would be really helpful if someone can provide the complete project which can be opened using Xilinx EDK. If better alternative exists to use openssl with xilinx toolchains please explain that also. Thanks in advance....

• How can I bind a winforms Opacity to a TrackBar (slider)

  - by Allen

  I've got a winform with a BindingSource that has an int property named Opacity in its DataSource. I also have a TrackBar on the winform that I want to use to control the Opacity of the winform. I've bound the Value property on the TrackBar to the Opacity and that functions just fine, sliding the TrackBar will change the variable from TrackBar.Minimum (0) to TrackBar.Maximum (1). I've also bound the Opacity property of the winform to this value, however, since the TrackBar's values only go from Minimum to Maximum in +/-1 rather than +/- .1 or so (like Opacity does), it doesn't properly fade the winform. Instead, 0 will turn it opaque and 1 will turn it fully visible. I need a way to work within the architecture described above, but get the TrackBar to change its value from 0 to 1 in defined increments smaller than 1.

• EMail Signing (Outlook) Using Smartcard Minidriver [Windows]

  - by Baget

  Hi I'm developing a Smart card Minidriver and I'm trying to Sign an Email using Outlook 2007. I have implemented all of the necessary functions in the minidriver. I'm able to create a "Smartcard User" certificate and save it and it's private key on the smartcard (using Microsoft Certificate Services via the Minidriver). When I try to sign an EMail via Outlook I'm getting Error Message (Internal Error), the last call to the minidriver is for ReadFile with "cmapfile" When I try to sign an EMail via Outlook with a difference non-smartcard certificate it's work fine. When I try to sign a Data using CryptoAPI (based on Windows SDK Sample) it's working fine. I'm using Windows 7. someone got any idea how to debug this issue? I tried to enable the CAPI2 eventlog, it don't give me any good information.
