• Is it safe to unset PHP super-globals if this behavior is documented?

  - by Stephen

  I'm building a PHP framework, and in it I have a request object that parses the url as well as the $_GET, $_POST and $_FILE superglobals. I want to encourage safe web habits, so I'm protecting the data against SQL injection, etc. In order to ensure users of this framework are accessing the safe, clean data through the request object, I plan to use unset($_GET, $_POST, $_REQUEST); after parsing those variables. I will document this in the method comments, and explain in the framework documentation that this is happening. My question is: Would this be desirable behavior? What are the potential pitfalls that I have not foreseen?

• Calling a WCF WebService in PHP via wsHttpBinding.

  - by Justin Dearing

  I have a WCF webservice I can connect to it via basicHttp, but not wsHttp. I try to conenct to it via wshttp via the following: $service = new SoapClient ("http://service.companyname.local:6666/Service/?wsdl", array( "location" => "http://service.companyname.local:6666/Service/WCF", "trace" => true, 'soap_version' => SOAP_1_2 ) ); The call to the SoapClient constructor returns fine. When I try to call one using $client-FunctionName, the page just sits there loading for quite a while, and eventually returns the error "Error Fetching http headers". What exactly is this supposed to mean and how do I fix it? (Consuming the service from .Net client works perfectly.)

• Question about inserting assembly code in C++

  - by Bruce

  I am working on VC++ compiler. I want to accomplish the following The variables s.AddrFrame.Offset and s.AddrStack.Offset contain the value of EBP and ESP respectively. I want to extract the value of old EBP and the return address. Assuming the address EBP + 1 contains the old 32 bit EBP value and EBP + 5 the return address I wrote the following code: unsigned int old_ebp = 0; unsigned int ret_addr = 0; __asm{ mov old_ebp, DWORD PTR [s.AddrFrame.Offset + 1] mov ret_addr, DWORD PTR [s.AddrStack.Offset + 5] } But this is not compiling xxxx.cpp(1130) : error C2415: improper operand type Please Help

• Controling CRT memory initialization

  - by Ofek Shilon

  Occasionally you meet bugs that are reproducible only in release builds and/or only on some machines. A common (but by no means only) reason is uninitialized variables, that are subject to random behaviour. E.g, an uninitialized BOOL can be TRUE most of the time, on most machines, but randomly be initialized as FALSE. What I wish I would have is a systematic way of flushing out such bugs by modifying the behaviour of the CRT memory initialization. I'm well aware of the MS debug CRT magic numbers - at the very least I'd like to have a trigger to turn 0xCDCDCDCD (the pattern that initializes freshly allocated memory) to zeros. I suspect one would be able to easily smoke out nasty initialization pests this way, even in debug builds. Am I missing an available CRT hook (API, registry key, whatever) that enables this? Anyone has other ideas to get there?

• Classic asp paging and session state

  - by flavour404

  Hi, Working on a classic asp page that uses paging. The error I am having a problem with is this: Lets say that you have 5 pages returned in your record set and you are on page 2. You leave and come back, you then press the link for page 3, the trouble is your session has timed out. I don't know why this happens but the page is reloaded, but the session check is bypassed and of course when the page attempts to retrieve the record set the session variables are now empty so I am getting a message stating: error near ',' line 1, because now the query is defunct. How do I get around this? Thanks, Ron.

• how to draw a Bitmap to a Canvas with a variable alpha

  - by steelbytes

  Hi, I'm trying to draw a Bitmap to a Canvas with a variable amount of alpha. But I only get nothing (when alpha<255) or the 'full' bitmap (when alpha==255). Have also tried loading as a Drawable, and using drawable.setAlpha, but that gave the same result. my init BitmapFactory.Options opts = new BitmapFactory.Options(); opts.inScaled = false; opts.inSampleSize = 1; Bitmap img = BitmapFactory.decodeResource(getResources(),R.drawable.sample,opts); my onDraw() Paint p = new Paint(Paint.ANTI_ALIAS_FLAG|Paint.FILTER_BITMAP_FLAG); p.setColor((alpha<<24)+0xffffff); // alpha in range 0..255 canvas.drawBitmap(img, null, imgRect, p);

• Problem with increment in inline ARM assembly

  - by tech74

  Hi , i have the following bit of inline ARM assembly, it works in a debug build but crashes in a release build of iphone sdk 3.1. The problem is the add instructions where i am incrementing the address of the C variables output and x by 4 bytes, this is supposed to increment by the size of a float. I think when i increment at some such stage i am overwriting something, can anyone say which is the best way to handle this Thanks C code that the asm is replacing, sum,output and x are all floats for(int i = 0; i< count; i++) sum+= output[i]* (*x++) asm volatile( ".align 4 \n\t" "mov r4,%3 \n\t" "flds s0,[%0] \n\t" "0: \n\t" "flds s1,[%2] \n\t" //"add %3,%3,#4 \n\t" "flds s2,[%1] \n\t" //"add %2,%2,#4 \n\t" "subs r4,r4, #1 \n\t" "fmacs s0, s1, s2 \n\t" "bne 0b \n\t" "fsts s0,[%0] \n\t" : : "r" (&sum), "r" (output), "r" (x),"r" (count) : "r0","r4","cc", "memory", "s0","s1","s2" );

• OOP question about functions that struck me all of a sudden.

  - by Nitesh Panchal

  Hello, May be my question is stupid. But i would like to get it cleared. We know that functions are loaded in memory only once and when you create new objects, only instance variables gets created, functions are never created. My question is, say suppose there is server and all clients access a method named createCustomer(). Say suppose all clients do something which fired createCustomer on server. So, if the method is in middle of execution and new client fires it. Will the new request be put on wait? or new request also will start executing the method? How does it all get managed when there is only one copy of function in memory? No book mentions answers to this type of questions. So i am posting here where i am bound to get answers :).

• When are referenced Assemblies loaded?

  - by Daniel

  I wrote a program that makes a reference to Microsoft.Web.Administration.dll, which is not present on Windows Server 2003. The program checks for the os and does not reference the dll if the os is 2003. if(OSVersion == WindowsServer2003) //do the job without referencing the Microsoft.Web.Administration.<br> else if(OSVersion == WindowsServer2008) //reference the Microsoft.Web.Administration.dll file.<br> When I tested this program on Windows Server 2003, an error occured telling me it couldn't locate the Microsoft.Web.Administration.dll. But when I separated the if-else block into 2 different methods as below, and the error did not occur. if(OSVersion == WindowsServer2003) //do the job without referencing the Microsoft.Web.Administration.<br> else if(OSVersion == WindowsServer2008) //DoIt2008Style(); So I wanted to know about reference file loading time in more detail. could you point me to some resources?

• Using Components.utils.import in a firefox extension

  - by jamesatha

  I am trying to create some global variables in a firefox extension. In my content folder, I have two javascript files: 1) Main JS file that holds the functions for the different events, etc 2) A file that stores only an object with the pieces of state I want to maintain. Also, I set the array EXPORTED_SYMBOLS. I am having issues with the following line found in my main JS file: Components.utils.import("resource:///globalVariables.js"); When it is at the top of the file, nothing seems to work. If I move it into the function where I need the variable, the rest of my code works, but the function with this line does nothing. Any advice that would help me with this problem would be great. Thanks

• How can I wait for the image to load in my new window before printing via child.print()?

  - by libertas

  $("#print").on('click', function () { var child = window.open("image.jpg", "_blank", "location=0,toolbar=0,scrollbars=1,fullscreen=1,menubar=0"); //any way to know/wait for image to load? child.print(); }); Any way for my parent window to know that the child window has completed loading the image prior to calling .print()? If they were trigger happy they would end up printing a blank page. I've tried both: child.attachEvent("onload", function () { child.print(); }); and child.attachEvent("DOMContentLoaded", function () { child.print(); }); //(found this online, apparently it's Firefox only, still didn't work)

• How do I stop intellij from adding specific jars to the classpath when debugging?

  - by AlecZorab

  When I debug an application in intellij, it insists on including all the jars in side my jre/lib folder and sub folders. Unfortunately, one of the libraries I use manually loads each class on the classpath at startup to reduce loading times during operation. As a result, debugging my app immediately results in the process spinning at 100% and then eventually dying. If I take the command line intellij uses and remove the jars in the lib folder from the classpath, the application executes as expected. How do I make intellij not include the jre libs?

• Selenium Webdrivers: Load Page without any resources

  - by Biffy

  I am trying to prevent Javascript from changing the site's source code I'm testing with Selenium. The problem is, I can't just simply turn Javascript off in the Webdriver, because I need it for a test. Here's what I'm doing for the Firefox Webdriver: firefoxProfile.setPreference("permissions.default.image", 2); firefoxProfile.setPreference("permissions.default.script", 2); firefoxProfile.setPreference("permissions.default.stylesheet", 2); firefoxProfile.setPreference("permissions.default.subdocument", 2); I don't allow Firefox to load any Images, Scripts and Stylesheets. How can I do this with the Internet Explorer Webdriver and the Chrome Webdriver? I have not found any similar preferences. Or is there even a more elegant way to stop the webdrivers from loading the site's JS Files after all? Thank you!

• Netbeans 7.2 not starting

  - by Buddhika Ariyaratne

  I recently installed Netbeans 7.2 beta and it worked fine. Then I installed Netbeans 7.2 final release on top of beta and during the installation, Netbeans 7.1 and Netbeans 7.12 were there. Now when I launch Netbeans, it does not go beyond "loading modules" stage. Simply the Netbeans screen disappear few seconds after the launch. Then I did the following. Uninstalled all the Netbeans versions and re-installed Netbeans 7.2 Deleted AppData/Netbeans folder Deleted User/.nbi folder Searched the registry and deleted Netbeans related entries. (But only one entry was found) Deleted Netbeans Folder in Program Files folder. Uninstalled and Re-installed in a separate drive. Uninstalled and Re-installed under another user account. None of the above worked, the only thing I did not try was to re-install the Windows XP operating system. It there any option to try before re-installing the operating system?

• .htaccess - deny downloading of files

  - by user317005

  I keep several fonts in the directory "/fonts/" on my server which I then load into my css files via @font-face. However, I want to make sure that people cannot download the file just by simply going to http://www.domain.com/fonts/fontname.ttf. Can I somehow prevent this, and still be able to load the font files into my css files? Because I think putting deny from all into the .htaccess file will even prevent the css files for correctly loading the fonts. I hope this makes sense.

• Breaking from for loop in MATLAB GUI

  I have a for loop in the opening function of a GUI in MATLAB and I'm trying to use a callback button to break the loop. I'm new to MATLAB.

Anyone know what's going on? Thanks.

• Build a Sitemap but webpages don't use links

  - by THX1138.6

  Folks I am trying to build a sitemap (we need one badly) for a huge multi-page web app. Technically its not much more than a collection of php/MySQL web forms that use javascript instead of traditional linkage to access the many pages. >td width="100" align="center" ONMOUSEOVER="this.className='bgover'" ONMOUSEOUT="this.className='bgout'" onclick="location.href='../main.php'">Main Page</td> Above is code sample of how the links are currently managed. I know I can search through the various pages, nearly a 1000, and find these "location.href" variables and that will help me a sitemap for each section. But maybe there is an easier way? WE use Trac and SVN so perhaps I am going about this the wrong way? Any advice would be appreciated.

• Where is Python support for PEM + RSA + DES3?

  - by jasonjs

  I need a Python library that supports PEM files and both RSA signing and DES3 encryption. pycrypto doesn't seem to support PEM, and its mechanism for loading existing keys is undocumented and cryptic. m2crypto doesn't seem to support DES/DES3, oddly. I've been running an openssl subprocess, but I'd rather have something built in and preferably fast. Does this exist? (Failing that, I hesitate to ask, but are there high-level enough C apis available for this that I could write a special-purpose extension without killing myself/introducing vulns?)
