  • Python virtualenv questions

    - by orokusaki
    I'm using VirtualEnv on Windows XP. I'm wondering if I have my brain wrapped around it correctly. I ran virtualenv ENV and it created C:\WINDOWS\system32\ENV. I then changed my PATH variable to include C:\WINDOWS\system32\ENV\Scripts instead of C:\Python27\Scripts. Then, I checked out Django into C:\WINDOWS\system32\ENV\Lib\site-packages\django-trunk, updated my PYTHON_PATH variable to point the new Django directory, and continued to easy_install other things (which of course go into my new C:\WINDOWS\system32\ENV\Lib\site-packages directory). I understand why I should use VirtualEnv so I can run multiple versions of Django, and other libraries on the same machine, but does this mean that to switch between environments I have to basically change my PATH and PYTHON_PATH variable? So, I go from developing one Django project which uses Django 1.2 in an environment called ENV and then change my PATH and such so that I can use an environment called ENV2 which has the dev version of Django? Is that basically it, or is there some better way to automatically do all this (I could update my path in Python code, but that would require me to write machine-specific code in my application)? Also, how does this process compare to using VirtualEnv on Linux (I'm quite the beginner at Linux).

  • How should I launch a Portable Python Tkinter application on Windows without ugliness?

    - by Andrew
    I've written a simple GUI program in python using Tkinter. Let's call this program 'gui.py'. My users run 'gui.py' on Windows machines from a USB key using Portable Python; installing anything on the host machine is undesirable. I'd like my users to run 'gui.py' by double-clicking an icon at the root of the USB key. My users don't care what python is, and they don't want to use a command prompt if they don't have to. I don't want them to have to care what drive letter the USB key is assigned. I'd like this to work on XP, Vista, and 7. My first ugly solution was to create a shortcut in the root directory of the USB key, and set the "Target" property of the shortcut to something like "(root)\App\pythonw.exe (root)\App\gui.py", but I couldn't figure out how to do a relative path in a windows shortcut, and using an absolute path like "E:" seems fragile. My next solution was to create a .bat script in the root directory of the USB key, something like this: @echo off set basepath=%~dp0 "%basepath%App\pythonw.exe" "%basepath%\App\gui.py" This doesn't seem to care what drive letter the USB key is assigned, but it does leave a DOS window open while my program runs. Functional, but ugly. Next I tried a .bat script like this: @echo off set basepath=%~dp0 start "" "%basepath%App\pythonw.exe" "%basepath%\App\gui.py" (See here for an explanation of the funny quoting) Now, the DOS window briefly flashes on screen before my GUI opens. Less ugly! Still ugly. How do real men deal with this problem? What's the least ugly way to start a python Tkinter GUI on a Windows machine from a USB stick?

  • Perl - how to get the number of elements in a list (not a named array)

    - by NXT
    Hi Everyone, I'm trying to get a block of code down to one line. I need a way to get the number of items in a list. My code currently looks like this: # Include the lib directory several levels up from this directory my @ary = split('/', $Bin); my @ary = @ary[0 .. $#ary-4]; my $res = join '/',@ary; lib->import($res.'/lib'); That's great but I'd like to make that one line, something like this: lib->import( join('/', ((split('/', $Bin)) [0 .. $#ary-4])) ); But of course the syntax $#ary is meaningless in the above line. Is there equivalent way to get the number of elements in an anonymous list? Thanks! PS: The reason for consolidating this is that it will be in the header of a bunch of perl scripts that are ancillary to the main application, and I want this little incantation to be more cut & paste proof.

  • SOAP Messages on iPhone

    - by CocoaNewBee
    Hello everyone !! I have to use several SOAP messages to get data from a web service. I got some examples how to do that but they all have the XML (http://icodeblog.com/2008/11/03/iphone-programming-tutorial-intro-to-soap-web-services/) // ---- LOGIN ----- NSString *soapMessage = [NSString stringWithFormat: @"<?xml version=\"1.0\" encoding=\"utf-8\"?>\n" "<soap12:Envelope xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\" xmlns:xsd=\"http://www.w3.org/2001/XMLSchema\" xmlns:soap12=\"http://www.w3.org/2003/05/soap-envelope\">\n" "<soap12:Body>\n" "<Login xmlns=\"http://tempuri.org/\">\n" "<sUserID>USER</sUserID>\n" "<sUserPw>PASSWORD</sUserPw>\n" "<sDomain>SERVER</sDomain>\n" "</Login>\n" "</soap12:Body>\n" "</soap12:Envelope>\n" ]; NSString *urlToSend = [[NSString alloc] initWithString:@"http://SERVER/DIRECTORY/WSDL_FILE.ASMX"]; NSString *callTOMake = [[NSString alloc] initWithString:@"http://WEBSERVER/Login"]; TWO questions: 1) Does it make sense to read the SOAP Message from a class or a file into xcode?? or sould I just define them thru the code ?? 2) I used SOAPUI & .NET to query the service. It works fine... but when I do it from the iphone simulator it returns the following: 2010-03-10 15:13:54.773 Hello_SOAP[91204:207] soap:ClientServer did not recognize the value of HTTP Header SOAPAction: http://WEBSERVER/DIRECTORY/Login How can I figure out what the issue is that's causing the said error on the simulator??

  • IIS 6+ASP.NET - many temp files generated

    - by moshe_ravid
    I have a ASP.NET + some .NET web-services running on IIS 6 (win 2003 server). The issue is that IIS is generating a lot (!) of files in "c:\WINDOWS\Temp" directory. a lot of files means thousands of files, which get to more than 3G of size so far. The files are generated by this command: C:\WINDOWS\SysWOW64\inetsrv "C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\csc.exe" /t:library /utf8output /R:"C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\Temporary ASP.NET Files\vfagt\113819dd\db0d5802\assembly\dl3\fedc6ef1\006e24d8_3bc9ca01\VfAgentWService.DLL" /R:"C:\WINDOWS\assembly\GAC_MSIL\System.Web.Services\2.0.0.0__b03f5f7f11d50a3a\System.Web.Services.dll" /R:"C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\mscorlib.dll" /R:"C:\WINDOWS\assembly\GAC_MSIL\System.Xml\2.0.0.0__b77a5c561934e089\System.Xml.dll" /R:"C:\WINDOWS\assembly\GAC_MSIL\System\2.0.0.0__b77a5c561934e089\System.dll" /out:"C:\WINDOWS\TEMP\9i_i2bmg.dll" /debug- /optimize+ /nostdlib /D:_DYNAMIC_XMLSERIALIZER_COMPILATION "C:\WINDOWS\TEMP\9i_i2bmg.0.cs" The files in the temp directory are pairs of *.out & *.err, where the *.err file is zero size, and the *.out file contains the compilation output messages. What is causing IIS to generate so many files? How can I prevent it? UPDATE: The problem is that the command i described above (csc.exe) is being executed many (many) times, causing the .out & .err to be generated so many times, until it consumes the disk space. So - my question is: what is causing this command to run so many times? (i don't have that many .aspx & .asmx files in my web app). Thanks, Moe

  • Reverse search in Hibernate Search

    - by Javi
    Hello, I'm using Hibernate Search (which uses Lucene) for searching some Data I have indexed in a directory. It works fine but I need to do a reverse search. By reverse search I mean that I have a list of queries stored in my database I need to check which one of these queries match with a Data object each time Data Object is created. I need it to alert the user when a Data Object matches with a Query he has created. So I need to index this single Data Object which has just been created and see which queries of my list has this object as a result. I've seen Lucene MemoryIndex Class to create an index in memory so I can do something like this example for every query in a list (though iterating in a Java list of queries would not be very efficient): //Iterating over my list<Query> MemoryIndex index = new MemoryIndex(); //Add all fields index.addField("myField", "myFieldData", analyzer); ... QueryParser parser = new QueryParser("myField", analyzer); float score = index.search(query); if (score > 0.0f) { System.out.println("it's a match"); } else { System.out.println("no match found"); } The problem here is that this Data Class has several Hibernate Search Annotations @Field,@IndexedEmbedded,... which indicated how fields should be indexed, so when I invoke index() method on the FullTextEntityManager instance it uses this information to index the object in the directory. Is there a similar way to index it in memory using this information? Is there a more efficient way of doing this reverse search? Thanks

  • How do I find and open a file in a Visual Studio 2005 add-in?

    - by Charles Randall
    I'm making an add-in with Visual Studio 2005 C# to help easily toggle between source and header files, as well as script files that all follow a similar naming structure. However, the directory structure has all of the files in different places, even though they are all in the same project. I've got almost all the pieces in place, but I can't figure out how to find and open a file in the solution based only on the file name alone. So I know I'm coming from, say, c:\code\project\subproject\src\blah.cpp, and I want to open c:\code\project\subproject\inc\blah.h, but I don't necessarily know where blah.h is. I could hardcode different directory paths but then the utility isn't generic enough to be robust. The solution has multiple projects, which seems to be a bit of a pain as well. I'm thinking at this point that I'll have to iterate through every project, and iterate through every project item, to see if the particular file is there, and then get a proper reference to it. But it seems to me there must be an easier way of doing this.

  • How to restrict a content of string to less than 4MB and save that string in DB using C#

    - by Pranay B
    I'm working on a project where I need to get the Text data from pdf files and dump the whole text in a DB column. With the help of iTextsharp, I got the data and referred it String.

  • How to get application context path in spring-ws?

    - by Dhaliwal
    I am using Spring-WS to create a webservice. In my project, I have created a Helper class to reads sample response and request xml file which are located in my /src/main/resource folder. When I am unit-testing my webservice application 'locally', I use the System.getProperty("user.dir") to get the application context folder. The following is a method that I created in the Helper class to help me retrieve the file that I am interested in my resource folder. public static File getFileFromResources(String filename) { System.out.println("Getting file from resource folder"); File request = null; String curDir = System.getProperty("user.dir"); String contextpath = "C:\\src\\main\\resources\\"; request = new File(curDir + contextpath + filename); return request; } However, after 'publishing' the compiled WAR file to the ../webapps folder to the Apache Tomcat directory, I realise that System.getProperty("user.dir") no longer returns my application context path. Instead, it is returning the Apache Tomcat root directory as shown C:\Program Files\Apache Software Foundation\Tomcat 6.0\src\main\resources\SampleClientFile I cant seem to find any information about getting the root folder of my webservice. I have seen examples on Spring web application where I can retrieve the context path by using the following : request.getSession().getServletContext().getContextPath() But in this case, I am using a Spring web application where there is a servlet context in the request. But the Spring-WS, my entry point is an endpoint. How can I get the context path of my webservice application. I am expecting a context path of something like C:\Program Files\Apache Software Foundation\Tomcat 6.0\webapps\clientWebService\WEB-INF\classes Could someone suggest a way to achieve this?

  • How to tell what account my webservice is running under in Visual Studio 2005

    - by John Galt
    I'm going a little nuts trying to understand the doc on impersonation and delegation and the question has come up what account my webservice is running under. I am logged as myDomainName\johna on my development workstation called JOHNXP. From Vstudio2005 I start my webservice via Debug and the wsdl page comes up in my browser. From Task Manager, I see the following while sitting at a breakpoint in my .asmx code: aspnet_wp.exe pid=1316 UserName=ASPNET devenv.exe pid=3304 UserName=johna The IIS Directory Security tab for the Virtual Directory that hosts my ws.asmx code has "Enable Anonymous access" UNCHECKED and has "Integrated Windows Authentication" CHECKED. So when the MSDN people state "you must configure the user account under which the server process runs", what would they be refering to in the case of my little webservice described above? I am quoting from: http://msdn.microsoft.com/en-us/library/aa302400.aspx Ultimately, I want this webservice of mine to impersonate whatever authenticated domain user browses through to an invoke of my webservice. My webservice in turn consumes another ASMX webservice on a different server (but same domain). I need this remote webservice to use the impersonated domain user credentials (not those of my webservice on JOHNXP). So its getting a little snarly for me to understand this and I see I am unclear about the account my web service uses. I think it is ASPNET in IIS 5.1 on WinXP but not sure.

  • How do I set an absolute include path in PHP?

    - by Nathan Long
    In HTML, I can find a file starting from the web server's root folder by beginning the filepath with "/". Like: /images/some_image.jpg I can put that path in any file in any subdirectory, and it will point to the right image. With PHP, I tried something similar: include("/includes/header.php"); ...but that doesn't work. I think that that this page is saying that I can set include_path once and after that, it will be assumed. But I don't quite get the syntax. Both examples start with a period, and it says: Using a . in the include path allows for relative includes as it means the current directory. Relative includes are exactly what I don't want. How do I make sure that all my includes point to the root/includes folder? (Bonus: what if I want to place that folder outside the public directory?) Clarification My development files are currently being served by XAMPP/Apache. Does that affect the absolute path? (I'm not sure yet what the production server will be.)

  • Android - Two different programs at the same time in an emulator

    - by Léa Massiot
    I'm new to Android development. My OS is WinXP. I'm trying to install two different applications on an Android Device Emulator in command line. I have two Android projects "ap1" and "ap2". In the "ap1" project directory, I ran "ant debug". I got an "ap1.apk" executable. In the "ap2" project directory, I ran "ant debug". I got an "ap2.apk" executable. I created an Android Virtual Device: cmd_line android create avd -n avd1 -t 1 --abi x86 I launched the emulator: cmd_line emulator -avd avd1 -verbose The "adb devices" command returns: List of devices attached emulator-5554 device I installed the first program on the emulator: cmd_line adb -s emulator-5554 install "ap1.apk" I ran the program: cmd_line adb shell am start -a android.intent.action.MAIN -n my.pkg.android/.Activity1 = It worked. I installed the second program on the emulator: cmd_line adb -s emulator-5554 install "ap2.apk" I ran the program: cmd_line adb shell am start -a android.intent.action.MAIN -n my.pkg2.android/.AnotherActivity1 = It worked. All this works except that the second executable "replaced" of the first one. If I try to run the first executable, I get an error: cmd_line adb shell am start -a android.intent.action.MAIN -n my.pkg.android/.Activity1 Starting: Intent { act=android.intent.action.MAIN cmp=my.pkg.android/.Activity1 } Error type 3 Error: Activity class {my.pkg.android/my.pkg.android.Activity1} does not exist. It looks like I can't have the two apps at the same time in the emulator. What do you think? What do I have to do to have the two apps available (at the same time) in the emulator? Thank you for helping. Best regards.

  • Enumerating computers in NT4 domain using WNetEnumResourceW (C++) or DirectoryEntry (C#)

    - by Kevin Davis
    I'm trying to enumerate computers in NT4 domains (not Active Directory) and support Unicode NetBIOS names. According to MSDN, WNetEnumResourceW is the Unicode counterpart of WNetEnumResource which to me would imply that using this would do the trick. However, I have not been able to get Unicode NetBIOS names properly using WNetEnumResourceW. I've also tried the C# rough equivalent DirectoryEntry using the WinNT: provider with no luck on Unicode names either. If I use DirectoryEntry on Active Directory (using the LDAP: provider) I do get Unicode names back. I noticed that during some debugging my code using DirectoryEntry and the WinNT: provider, the exceptions I saw were of type System.Runtime.InteropServices.COMException which tends to make me believe that this is just calling WNetEnumResourceW via COM. This web page implies that for some Net APIs the MS documentation is incomplete and possibly inaccurate which further confuses things. Additionally I've found that using the C# method which certainly results in cleaner, more understandable code also yields incomplete results in enumerating computers in domains\workgroups. Does anyone have any insight on this? Is it possible that computer acting as the WINS server is mangling the name? How would I determine this? Thanks

  • Why does my CGI script keep redirecting links to localhost?

    - by Noah Brainey
    Visit this page http://online-file-sharing.net/tos.html and click one of the bottom footer links. It redirects you to your localhost in the address bar. I have no idea why it does this. This is in the main script that my entire website revolves around: upload.cgi $ENV{PATH} = '/bin:/usr/bin'; delete @ENV{'IFS', 'CDPATH', 'ENV', 'BASH_ENV'}; ($ENV{DOCUMENT_ROOT}) = ($ENV{DOCUMENT_ROOT} =~ /(.*)/); # untaint. #$ENV{SCRIPT_NAME} = '/cgi-bin/upload.cgi'; use lib './perlmodules'; #use Time::HiRes 'gettimeofday'; #my $hires_start = gettimeofday(); my (%PREF,%TEXT) = (); No file is displayed when someone visits the root directory, although I have a .htaccess file saying to open my upload.cgi file which is located in my root directory. When I point my browser directly to the CGI file it works but it brings me to my localhost again. I'm hosting this website on my own server, which is this computer, and using XAMPP if this information helps. I'm also using DynDNS as my nameservers. I hope you can give me some insight.

  • Taking my ASP.NET from my local comp to the server

    - by Andrew G. Johnson
    Hi All, So I have been developing a small ASP.NET web app in C# for my company over the past few weeks and now I am trying to push it onto our Rackspace server. First step was to create a virtual directory because we want it to be www.ourdomain.com/appname/ and most of the stuff on ourdomain.com is currently in classic ASP. So I did this and then uploaded my stuff to the new folder. I *think* I did this at least semi-right because the error message I am getting is that nice puke color (ASP.NET style instead of classic ASP style) -- problem is it is generic and just saying runtime error. I tried just copy/pasting <customErrors mode="On" /> into the web.config file in the /appname/ directory but nothing changed So the actual questions are: How can I get a more descriptive error, when I was developing locally I just pushed the "play button" in VS2010 and it would either show me the app or tell me where I screwed up Is there anything else I'm doing wrong that may be causing this? If there's things I need to check lemme know!

  • Why am I getting a permission denied error on my public folder?

    - by Robin Fisher
    Hi all, This one has got me stumped. I'm deploying a Rails 3 app to Slicehost running Apache 2 and Passenger. My server is running Ruby 1.9.1 using RVM. I am receiving a permission denied error on the "public" folder in my app. My Virtual Host is setup as follows: <VirtualHost *:80> ServerName sharerplane.com ServerAlias www.sharerplane.com ServerAlias *.sharerplane.com DocumentRoot /home/robinjfisher/public_html/sharerplane.com/current/public/ <Directory "/home/robinjfisher/public_html/sharerplane.com/public/"> AllowOverride all Options -MultiViews Order allow,deny Allow from all </Directory> PassengerDefaultUser robinjfisher </VirtualHost> I've tried the following things: trailing slash on public; no trailing slash on public; PassengerUserSwitching on and off; PassengerDefaultUser set and not set; with and without the block. The public folder is owned by robinjfisher:www-data and Passenger is running as robinjfisher so I can't see why there are permission issues. Does anybody have any thoughts? Thanks Robin PS. Have disabled the site for the time being to avoid indexing so what is there currently is not the site in question.

  • Issues with intellisense, references, and builds in Visual Studio 2008

    - by goober
    Hoping you can help me -- the strangest thing seems to have happened with my VS install. System config: Windows 7 Pro x64, Visual Studio 2008 SP1, C#, ASP.NET 3.5. I have two web site projects in a solution. I am referencing NUnit / NHibernate (did this by right-clicking on the project and selecting "Add Reference". I've done this for several projects in the past). Things were working fine but recently stopped working and I can't figure out why. Intellisense completely disappears for any files in my App_Code directory, and none of the references are recognized (they are recognized by any file in the root directory of the web site project. Additionally, pretty simple commands like the following (in Page_Load) fail (assume TextBox1 is definitely an element on the page): if (Page.IsPostBack) { str test1; test1 = TextBox1.Text; } It says that all the page elements are null or that it can't access them. At first I thought it was me, but due to the combination of issues, it seems to be Visual Studio itself. I've tried clearing the temp directories & rebuilding the solution. I've also tried tools -- options -- text editor settings to ensure intellisense is turned on. I'd appreciate any help you can give!

  • LNK 1104 error to lib file - Continues despite removing includes and links

    - by user1556594
    A link error to a lib file popped up out of the blue in a c++ application of mine after code was working fine in my last session. Error 1 error LNK1104: cannot open file '..........\Program Files (x86)\FMOD SoundSystem\FMOD Programmers API Windows\api\lib\fmodex_vc.lib' I triple checked my project directories were set up correctly to link to the lib file, that the file existed in said directory and that it was a working version of the .lib. My next step was to remove the includes to the file and the links to bypass the error and work on the rest of my code until the problem was solved. The error remains, however, despite: Commenting out absolutely every include relating to the lib. Commenting out absolutely every line of code dependant on the includes. Removing the directory from VC++ Directories in the project properties. Checking the Additional Library Directories field was also clear of references. To my understanding this should have made the library and related code virtually non-existant to the compiler. What am I missing? The library itself is fmodex_vc.lib - part of the FMOD API for providing sound to interactive applications. Again, the application was working one session, but failed to compile the next. I hadn't touched the code since so this led me to believe some aspect of VS is at fault. I'd like to avoid the time involded in re-installing if possible as I'm on the clock for a review tomorrow evening and there are a few more things I'd like to smooth out before then. If necessary, however, I won't hesitate. Very much appreciate the help.

  • Make Errors: Missing Includes in C++ Script?

    - by czy1985
    i am a newbie learning sml and the question i am thrown with involves IO functions that i have no idea how it works even after reading it. Here is the 2 questions that i really need help with to get me started, please provide me with codings and some explaination, i will be able to trial and error with the code given for the other questions. Q1) listdir(filename,directoryname), which given the name of a directory, list its contents in a text file. The listing is in a form that makes it easy to seperate filenames, dates and sizes from each other. (similar to what msdos does with "dir" but instead of just listing it out, it places all the files and details into a text file. Q2) readlist(filename) which reads a list of filenames (each of which were produced by listdir in (Q1) and combines them into one large list. (reads from the text file in Q1 and then assigning the contents into 1 big list containing all the information) Thing is, i only learned from the lecturer in school on the introduction section, there isnt even a system input or output example shown, not even the "use file" function is taught. if anyone that knows sml sees this, please help. Thanks to anyone who took the effort helping me. Thanks for the reply, current I am using SMLNJ to try and do this. Basically, Q1 requires me to list the directory's files of the "directoryname" provided into a text file in "filename". The Q2 requires me to read from the "filename" text file and then place the contents into one large list. Duplicate of: smlnj listdir

  • How might I wrap the FindXFile-style APIs to the STL-style Iterator Pattern in C++?

    - by BillyONeal
    Hello everyone :) I'm working on wrapping up the ugly innards of the FindFirstFile/FindNextFile loop (though my question applies to other similar APIs, such as RegEnumKeyEx or RegEnumValue, etc.) inside iterators that work in a manner similar to the Standard Template Library's istream_iterators. I have two problems here. The first is with the termination condition of most "foreach" style loops. STL style iterators typically use operator!= inside the exit condition of the for, i.e. std::vector<int> test; for(std::vector<int>::iterator it = test.begin(); it != test.end(); it++) { //Do stuff } My problem is I'm unsure how to implement operator!= with such a directory enumeration, because I do not know when the enumeration is complete until I've actually finished with it. I have sort of a hack together solution in place now that enumerates the entire directory at once, where each iterator simply tracks a reference counted vector, but this seems like a kludge which can be done a better way. The second problem I have is that there are multiple pieces of data returned by the FindXFile APIs. For that reason, there's no obvious way to overload operator* as required for iterator semantics. When I overload that item, do I return the file name? The size? The modified date? How might I convey the multiple pieces of data to which such an iterator must refer to later in an ideomatic way? I've tried ripping off the C# style MoveNext design but I'm concerned about not following the standard idioms here. class SomeIterator { public: bool next(); //Advances the iterator and returns true if successful, false if the iterator is at the end. std::wstring fileName() const; //other kinds of data.... }; EDIT: And the caller would look like: SomeIterator x = ??; //Construct somehow while(x.next()) { //Do stuff } Thanks!

  • PHP + CURL How to get file name

    - by Gunjan
    I'm trying to download users profile picture from facebook in PHP using this function public static function downloadFile($url, $options = array()) { if (!is_array($options)) $options = array(); $options = array_merge(array( 'connectionTimeout' => 5, // seconds 'timeout' => 10, // seconds 'sslVerifyPeer' => false, 'followLocation' => true, // if true, limit recursive redirection by 'maxRedirs' => 2, // setting value for "maxRedirs" ), $options); // create a temporary file (we are assuming that we can write to the system's temporary directory) $tempFileName = tempnam(sys_get_temp_dir(), ''); $fh = fopen($tempFileName, 'w'); $curl = curl_init($url); curl_setopt($curl, CURLOPT_FILE, $fh); curl_setopt($curl, CURLOPT_CONNECTTIMEOUT, $options['connectionTimeout']); curl_setopt($curl, CURLOPT_TIMEOUT, $options['timeout']); curl_setopt($curl, CURLOPT_HEADER, false); curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, $options['sslVerifyPeer']); curl_setopt($curl, CURLOPT_FOLLOWLOCATION, $options['followLocation']); curl_setopt($curl, CURLOPT_MAXREDIRS, $options['maxRedirs']); curl_exec($curl); curl_close($curl); fclose($fh); return $tempFileName; } The problem is it saves the file in the /tmp directory with a random name and without the extension. How can I get the original name of the file (I'm more interested in the original extension) The important things here are: The url actually redirects to image so i cant get it from original url the final url does not have the file name in headers

  • How to debug an external library (OpenCV) in Visual C++?

    - by neuviemeporte
    I am developing a project in VC++2008. The project uses the OpenCV library (but I guess this applies to any other library). I am working with the Debug configuration, the linker properties include the debug versions of the library .lib's as additional dependencies. In VC++ Directories under Tools|Options i set up the include directory, the .lib directory, the source directories for the library as well. I get an error while calling one of the functions from the library and I'd like to see exactly what that function is doing. The line that produces the error is: double error = cvStereoCalibrate(&calObjPointsM, &img1PointsM, &img2PointsM, &pointCountsM, &cam1M, &dist1M, &cam2M, &dist2M, imgSize, &rotM, &transM, NULL, NULL, cvTermCriteria(CV_TERMCRIT_ITER + CV_TERMCRIT_EPS, 100, 1e-5)); I set up a breakpoint at this line to see how the cvStereoCalibrate() function fails. Unfortunately the debugger won't show the source code for this function when I hit "Step into". It skips immediately to the cvTermCriteria() (which is a simple inline, macro-kinda function) and show its contents. Is there anything else I need to do to be able to enter the external library functions in the debugger? EDIT: I think the cvTermCriteria() function shows in the debugger, because it's defined in a header file, therefore immediately accesible to the project.

  • How to install Zend Framework on Windows

    - by sombe
    "installing Zend Framework is so easy!!!!" yeah right... Ok I'm working with a beginner's book and the ONE thing that is not excessively detailed is the most important part: Installing the darn thing. After browsing the quickstart guide for hours, all it said was: "download Zend [...] add the include directory (bla bla) and YOU'RE DONE!" right, i'm done using Zend. Ok, not really, not yet anyway. I beg of you people, I wanna go to bed, please tell me how (in simple 6th grade detail) to install the framework. I've got the unzipped folder in my htdocs directory, and I placed zf.bat+zf.php in the htdocs root. What's next? thank you so much. EDIT: Thanks guys for all the answers. Unfortunately I haven't been able to work with this or find a good enough resource to explain it to me in plain english. It seems that this framework adheres more so to programmers than to beginners. I've since yesterday read a little on CakePHP and found that it was incredibly easy to install and tune. As oppose to Zend Framework, where I had to dig in my "environment variables", configure "httpd.conf" and almost tie the knot between my computer driver cables to just get it running, CakePHP has already allowed me to put together a nice newbie application. In conclusion, I very much appreciate all of your help. I hope someone else venturing on ZF will be more successful with it. Thanks!
