• C++ Access violation when calling dll function

  - by Manjoor

  I have a function definition in my VC++ Win32 DLL DEMO2_API void ProcessData(char* i_buff, unsigned short i_len, char* o_buf, unsigned *o_len, unsigned short *errorCode) { __describe (i_buff,&i_len,o_buf,o_len,errorCode); } This dll function is called by a c# application. When called, it generate access violation exception. After reasearching i found, the cause for my problem. http://social.msdn.microsoft.com/Forums/en-US/csharplanguage/thread/6e843243-baf4-4eb1-8a20-c691ad47762c But could not understand what exactly they are doinng in example code. Can someone explain it so me? And what would be P/Invoke signature in c# after externally allocating memory?

• Installing Silverstripe on 000webhost.com (free web host)

  - by benwad

  Hi I'm trying to learn how to work Silverstripe so I extracted the tar file to my free hosting account. I then went on install.php and edited the permissions to meet the requirements set out in install.php but I still get two warnings from the 'webserver configuration' section: I can't tell what webserver you are running. Without Apache I can't tell if mod_rewrite is enabled. I can't tell whether mod_rewrite is running. You may need to configure a rewriting rule yourself. I looked in phpinfo() and mod_rewrite appears to be installed. I contacted the web host and they said it was to do with virtual directory paths, and I should add 'RewriteBase /' to the top of my .htaccess file in the public_html directory. However I did this and still had the same problem. The install.php script says that I can install it even with these warnings but when I press 'install' it just refreshes the install.php page. It doesn't even overwrite the .htaccess file. 000webhost.com says they have successfully installed Silverstripe on their user accounts without much configuration but I can't seem to find out how. EDIT: I managed to get to the next page but now there is another warning which is stopping it installing: Friendly URLs are not working. This is most likely because mod_rewrite isn't configuredcorrectly on your site. Please check the following things in your Apache configuration; you may need to get your web host or server administrator to do this for you: * mod_rewrite is enabled * AllowOverride All is set for your directory I also get this error message from the server: Warning: unlink(mysite/_config.php) [function.unlink]: Permission denied in /home/a2716553/public_html/install.php on line 701

• Debugging mod_rewrite

  - by nickf

  I'm playing around with Apache's mod_rewrite module, and want to know if there is a decent way to output some debugging information? For example, the documentation lists a number of variables available: %{HTTP_USER_AGENT}, %{HTTP_REFERER}, %{HTTP_COOKIE} ... etc Is there a way I could output these just to see what I'm working with? I set up the RewriteLog (Level 2) and have been looking at that, but it'd be nice to be able to see the value of the variables.

• How can I get the name of the uploaded file in HTML::Mason?

  - by marghi

  Recently I've been trying to get some files uploaded on to my server in my HTML::Mason application. All good, no problems there. Apparently Mason returns a filehandle directly in the argument. The problem is that I cannot retrieve the filename from that filehandle in a elegant way. One method of resolving this issue is parsing the filename on the client before sending it to the server and placing the extracted value in a hidden field so that it gets sent upon submit. BUT that is very unsafe!

• mod_deflate Supported Encodings for Compression

  - by sparc

  It seems to me, that mod_deflate in Apache 2.2 will always return: Content-Encoding: gzip and never: Content-Encoding: deflate It was explained to me, that although there may be a deflate algorithm, mod_deflate is named after a file-format, in which the algorithm could be any of: gzip, bzip. pkzip Of those three, mod_deflate provides gzip. It seems as though gzip is the most popular and widely-supported algorithm in web browsers, but I know some web servers and proxies do return Content-Encoding: deflate. Aside from the confusion of the module's name, it true that mod_deflate will only return Content-Encoding: gzip? Thank you.

• Tailing 'Jobs' with Perl under mod_perl

  - by Matthew

  Hi everyone, I've got this project running under mod_perl shows some information on a host. On this page is a text box with a dropdown that allows users to ping/nslookup/traceroute the host. The output is shown in the text box like a tail -f. It works great under CGI. When the user requests a ping it would make an AJAX call to the server, where it essentially starts the ping with the output going to a temp file. Then subsequent ajax calls would 'tail' the file so that the output was updated until the ping finished. Once the job finished, the temp file would be removed. However, under mod_perl no matter what I do I can's stop it from creating zombie processes. I've tried everything, double forking, using IPC::Run etc. In the end, system calls are not encouraged under mod_perl. So my question is, maybe there's a better way to do this? Is there a CPAN module available for creating command line jobs and tailing output that will work under mod_perl? I'm just looking for some suggestions. I know I could probably create some sort of 'job' daemon that I signal with details and get updates from. It would run the commands and keep track of their status etc. But is there a simpler way? Thanks in advance.

• Java applet - access denied to file on same web server

  - by me_here

  I've written a simple Java applet to generate a technical image based upon some data in a CSV file. I'm passing in the CSV file as a parameter to the applet: <applet code = "assaymap.AssayMapApplet" archive = "http://localhost/applet_test/AssayMap.jar" height="600px" width="800px"> <param name="csvFile" value="http://localhost/applet_test/test.csv"> </applet> As far as I understood applet security restrictions, an applet should be able to read data from the host they're on. These applets here http://www.jalview.org/examples/applets.html are using the same approach of passing in a text data file as a parameter. So I'm not sure why my own applet isn't working. The error message I get thrown is: Error with processing the CSV data. java.security.AccessControlException: access denied (java.io.FilePermission http:\localhost\applet_test\test.csv read)

• Exclude a URL from rewrite in .htaccess with "last" flag

  - by songdogtech

  WordPress has been installed as a blog into osCommerce. I'm trying to get the WordPress RSS feed to work. All WP core files exist, but I get all kinds of errors accessing the feed at mydomain.com/wordpress/feed/, like 404s, "the feed can't be updated because the source file is no longer available," or even raw php code in the browser from the osCommerce feed file. I think the problem is the rewrite rules for osCommerce, and I'm thinking if I can exclude the WP feed URL from rewrite, it will fix the feed or help find the real issue. Looking around SO, I found a solution to use the "last" flag on a URL to prevent it from being rewritten. Problem is, the existing .htaccess already has a rule with a "last" flag on it: RewriteCond %{REQUEST_FILENAME} !-f RewriteCond %{REQUEST_FILENAME} !-d RewriteRule ^(.*)/$ http://www.mydomain.com/index.php?cPath=$1 [L] Is there a way to not rewrite the WP feed URL? Can another "last" rule be added? I'd like to have some definite things to try before messing with .htaccess to avoid disrupting the site.

• mod_rewrite/GoDaddy problem

  - by John Deerhake

  Ok, so I really don't know much about mod_rewrite and I'm looking over the apache docs and still not figuring this out. Here is my htaccess (which is mostly just copy & pasted from a site I found): .htaccess in base dir: <IfModule mod_rewrite.c> RewriteEngine on RewriteRule ^$ public/ [L] RewriteRule (.*) public/$1 [L] </IfModule> .htaccess in /public dir: <IfModule mod_rewrite.c> RewriteEngine On RewriteCond %{REQUEST_FILENAME} !-f RewriteCond %{REQUEST_FILENAME} !-d RewriteRule ^(.*)$ index.php?url=$1 [PT,L] </IfModule> Basically I'm using the above htaccess files on my current test server and it works great and exactly like I would expect (everything gets seamlessly redirected to public dir). Now when I throw this on my GoDaddy hosting account i get "Internal Server Errror". I've done some searching and I'm fairly certain I should be able to use mod_rewrite with GoDaddy. I suspect this is because I'm not using the base directory to host the site in. The site is in in the folder html/myapp/ (where html is the base directory) and i have a subdomain set up in GoDaddy to look in that folder.

• Access SDExplorer (System Folder) from my C# app

  - by Søren

  Hello everyone I am trying out Windows Live SkyDrive, and I installed SDExplorer (http://www.cloudstorageexplorer.com/) It works by adding my SkyDrive folder to Windows Explorer, but it does not get a drive name or anything, so how can I access that drive/folder from my C# application? When I go into the folder and look at the address bar it says "Computer\SDExplorer". Directory.GetDirectories(@"\Computer\SDExplorer") does not work, because it translates to "C:\Computer\SDExplorer". I would like to be able to create a small application that can create folders and upload files to my SkyDrive account. Anybody know how these special folder/drives work? - I noticed MozyHome appears in the same way in my Windows Explorer.

• restrict access to page to only be allowed from a certain page

  - by controlfreak123

  This question is similar to the one i asked here. But its related because I want to achieve the same effect. I want the users to be restricted to only accessing other pages on the site through the main page. The first page contains a frame for navigation and then a frame for content of the page they navigate to. I want it to be setup so that the only way they can access the content pages is by using this main page. So if the main page is http://intranet/index.html then they cannot get to http://intranet/other_page.html without using the link provided in index.html. Is this possible and if so what would the best technique be? I'm using apache to serve the site and I have php and javascript available.

• Using RouteExistingFiles to block access to existing files even if no route exists

  - by Michael Stum

  In ASP.net MVC 2, I can use routes.RouteExistingFiles = true; to send all requests through the routing system, even if they exist on the file system. Usually, this ends up hitting the "{controller}/{action}/{id}" route and throws an exception as the controller cannot be found. I do not want to use that route though (I have only a few URLs and they are specifically mapped), yet I would still like to prevent access to the file system. Basically I want to Whitelist pages using IgnoreRoute. Is there a built-in way to do this? My current approach is to still have the "{controller}/{action}/{id}" route and generate a 404 when this is hit, but I'm just wondering if something is built-in already?

• shutil.rmtree fails on Windows with 'Access is denied'

  - by Sridhar Ratnakumar

  In Python, when running shutil.rmtree over a folder that contains a read-only file, the following exception is printed: File "C:\ActivePython32Python26\lib\shutil.py", line 216, in rmtree rmtree(fullname, ignore_errors, onerror) File "C:\ActivePython32Python26\lib\shutil.py", line 216, in rmtree rmtree(fullname, ignore_errors, onerror) File "C:\ActivePython32Python26\lib\shutil.py", line 216, in rmtree rmtree(fullname, ignore_errors, onerror) File "C:\ActivePython32Python26\lib\shutil.py", line 216, in rmtree rmtree(fullname, ignore_errors, onerror) File "C:\ActivePython32Python26\lib\shutil.py", line 216, in rmtree rmtree(fullname, ignore_errors, onerror) File "C:\ActivePython32Python26\lib\shutil.py", line 216, in rmtree rmtree(fullname, ignore_errors, onerror) File "C:\ActivePython32Python26\lib\shutil.py", line 216, in rmtree rmtree(fullname, ignore_errors, onerror) File "C:\ActivePython32Python26\lib\shutil.py", line 221, in rmtree onerror(os.remove, fullname, sys.exc_info()) File "C:\ActivePython32Python26\lib\shutil.py", line 219, in rmtree os.remove(fullname) WindowsError: [Error 5] Access is denied: 'build\\pyhg_trunk-win32-x86-hgtip27\\image\\feature-core\\INSTALLDIR\\tcl\\tcl8.5\\msgs\\af.msg' Looking in File Properties dialog I noticed that af.msg file is set to be read-only. So the question is: what is the simplest workaround/fix to get around this problem - given that my intention is to do an equivalent of rm -rf build/ but on Windows? (without having to use unxutils or cygwin)

• Apache deflate with chucked encoding

  - by hoodoos

  I'm expiriencing some problem with one of my data source services. As it says in HTTP response headers it's running on Apache-Coyote/1.1. Server gives responses with Transfer-Encoding: chunked, here sample response: HTTP/1.1 200 OK Server: Apache-Coyote/1.1 Content-Type: text/xml;charset=utf-8 Transfer-Encoding: chunked Date: Tue, 30 Mar 2010 06:13:52 GMT And problem is when I'm requesting server to send gzipped request it often sends not full response. I recieve response, see that last chunk recived, but then after ungzipping I see that response is partial. So my question is: is it common apache issue? maybe one of it's mod_deflate plugins or something? Ask questions if you need more info. Thanks.

• Access Violation Exception only appearing when running C# app without debugger attached

  - by Jon

  I have an application that works fine in Visual Studios 2008, and I am trying to get it into VS 2010 in order to use .NET 4, and I have a really weird problem. When I run the code from either Release mode or Debug mode with the debugger attached (F5), I have no problems running the program. However, when I run the program from either Release or Debug without the debugger attached (Shift+F5), I get an Access Violation Exception when I attempt to run some code in a dll from GDCM. I've created the dlls by using CMake and Swig and following the instructions here adjusting the instructions where necessary to build for VS 2010 and .NET 4. Does any one have any ideas why this is happening and how I can fix it?

• Access to Apache::DBI from DBI

  - by hpavc

  Is it possible to access a Apache::DBI database handle from a perl script (that isn't running under mod_perl). What I am looking for is database pooling for my perl scripts, I have a fair number of database sources (oracle/mysql) and a growing number of scripts. Some ideas like SQLRelay, using Oracle10XE with database links and pooling, and or convert all scripts to SOAP calls, etc are becoming more and more viable. But if there was a mechanism for reusing Apache::DBI I could fight this a bit. I have no non-perl requirements, so we don't have a php/jdbc implementation or similar to deal with. Thanks

• Access Adobe InDesign files

  I need some directions for the following problem: I have a lot of InDesign files and i have to setup a process that will track if a certain paragraph or text block has changed between diferent versions of the file. If the text block has changed i want to extract that text block in a "portable" format (html, pdf, txt). Is there an Adobe product that would do that ? Is there any public API to access an InDesign file ? Is there the posibility to export InDesign to, say, html ?

• "Could not load file or assembly" error on trying to access auxillary assemblies from COM

  - by Codex

  We have the project structure as follows: COMExposedCCW.dll -refers- BusinessLayer.dll -refers- Utils.dll COMExposedCCW.dll -refers- Utils.dll The COMExposedCCW.dll has been registered for COM interop. From the COM application{Excel} we can successfully create the CCW object and access its properties, but when we try to invoke methods that refer to the Business/Utils layer, it throws an exception that the file or assembly{Business/Utils} could not be found. The Business/Utils dlls are present in the same folder as the CCW. On copying the Business/Utils to the COM application directory it works fine. I've tried the following: Set "HintPath/" in the CCW project I dont want to dynamically load the assemblies using Reflection {there should be a more elegant solution} Thanks in advance.
