  • C++ vector and struct problem win32

    - by ~james2432
    I have a structure defined in my header file: struct video { wchar_t* videoName; std::vector<wchar_t*> audio; std::vector<wchar_t*> subs; }; struct ret { std::vector<video*> videos; wchar_t* errMessage; }; struct params{ HWND form; wchar_t* cwd; wchar_t* disk; ret* returnData; }; When I try to add my video structure to a vector of video* I get access violation reading 0xcdcdcdc1 (videoName is @ 0xcdcdcdcd, before I allocate it) //extract of code where problem is video v; v.videoName = (wchar_t*)malloc((wcslen(line)+1)*sizeof(wchar_t)); wcscpy(v.videoName,line); p->returnData->videos.push_back(&v); //error here

  • Keeping some files private

    - by user490895
    Hi, I was trying to create a directory of private files that could only be accessed when a user logs in. To do this, I used a folder outside the web directory, and then php to access it, if allowed. Here's an example: function display_movie($file){ printf("<video id='movie' width='960' height='416' controls='controls' onerror='fix()'> <source src='movie.php?file=%s' type='video/ogg; codecs=\"theora, vorbis\"'> </video>", rawurlencode($file)); } This works great for images, but breaks the media player. Also, I've only tested this locally on a Linux machine. Any ideas? Thanks.

  • Why is this consider bad practice? or is it? (ASP.Net)

    - by user318573
    Would this code be considered bad practice: <div id="sidebar"> <% =DisplayMeetings(12) %> </div> This is a snippet of code from the default.aspx of a small web app I have worked on. It works perfectly well, runs very fast, but as always, I am aware of the fact that just because it works, doesn't mean it is OK. Basically, the DisplayMeetings subroutine outputs a bunch of formatted HTML (an unordered list actually), with no formatting, just the requisite html, and then my CSS performs all the necessary formatting. The data for generating the list comes from an SQL server database (the parameter controls how many rows to return) and I am using stored procedures and datareader for fast access. This keeps my front-end extraordinary simple and clean, imho, and lets me do all the work in VB or C# in a separate module. I could of course use a databound repeater (and probably 6 or more other methods) of accomplishing the same thing, but are they any better? Other than loosing the design-time features of VS2010?

    I have this Java object private List<NewAccountObj> dataList; public class NewAccountObj { private int userid; public NewAccountObj(int userid) { this.userid = userid; } public int getUserid() { return userid; } public void setUserid(int userid) { this.userid = userid; } public List<NewAccountObj> getdataList() { return dataList; } What is the proper way to access a value from the object?

  • Shared data in an ASP.NET application

    - by Barguast
    I have a basic ASP.NET application which is used to request data which is stored on disk. This is loaded from files and sent as the response. I want to be able to store the data loaded from these files in memory to reduce the number of reads from disk. All of the requests will be asking for the same data, so it makes sense to have a single cache of in-memory data which is accessible to all requests. What is the best way to create a single accessible object instance which I can use to store and access this cached data? I've looked into HttpApplication, but apparently a new instance of this is created for parallel requests and so it doesn't fit my needs.

  • How to track down a Blue Screen of Death triggered by an (usermode) application

    - by mhenry1384
    We have a .Net application consisting of mixed managed and unmanaged code. We have a number of reports of users getting BSOD while using our application. These blue screens happen on different versions of Windows. Mostly XP but one user claims it happens on Windows 7. Some users see it happening when doing one thing, other see it happening when doing something completely different. Of course, we cannot reproduce the problem. Needless to say, I'm stumped. A user mode application shouldn't be able to blue screen the OS so we are running into a bug in a common kernel space application, perhaps buggy antivirus software? Does anyone have any tips on how to track something like this down? We don't have access to a computer where this is happening so we wouldn't be able to hook up a kernel debugger or anything like that.

  • Silverlight Windows Phone 7: Load Images From URL

    Hi, I got the code below that is trying to load an image from the web into an Image control, when I run it I get an error on the given line that no network access is allowed: private void button1_Click(object sender, RoutedEventArgs e) { WebClient webClientImgDownloader = new WebClient(); webClientImgDownloader.OpenReadCompleted += new OpenReadCompletedEventHandler(webClientImgDownloader_OpenReadCompleted); webClientImgDownloader.OpenReadAsync(new Uri("http://dilbert.com/dyn/str_strip/000000000/00000000/0000000/000000/80000/5000/100/85108/85108.strip.print.gif", UriKind.Absolute)); } void webClientImgDownloader_OpenReadCompleted(object sender, OpenReadCompletedEventArgs e) { BitmapImage bitmap = new BitmapImage(); bitmap.SetSource(e.Result); // ERROR HERE! image1.Source = bitmap; } Silverlight for Windows Phone 7

  • different ways of getting the IP Address

    - by Sachindra
    I was actually going through the question 1636644 .. and got confused with this " The getenv() function access to any environment variable to get the related value! " Also .. " It would probably be better to use $_SERVER['REMOTE_ADDR']; to prevent incompatibilities between servers. " what kind of compatibility issue can this be ?? Lastly, it says $_SERVER is an array with many elements but I find only the IP Address there .. does this array store anything else too??? apologies for all these questions packed in one .. this is bcoz these are all related ..

  • How to pass a file (read from Java) most effectively to a native method?

    - by soc
    Hi, I have approx. 30000 files (1MB each) which I want to put into a native method, which requires just an byte array and the size of it as arguments. I looked through some examples and benchmarks (like http://nadeausoftware.com/articles/2008/02/java_tip_how_read_files_quickly) but all of them do some other fancy things. Basically I don't care about the contents of the file, I don't want to access something in that file or the byte array or do anything else with it. I just want to put a file into a native method which accepts an byte array as fast as possible. At the moment I'm using RandomAccessFile, but that's horribly slow (10MB/s). Is there anything like byte[] readTheWholeFile(File file){ ... } which I could put into native void fancyCMethod(readTheWholeFile(myFile), myFile.length()) What would you suggest?

  • How to set CSS style colors in GWT

    - by AmaltasCoder
    I have a GWT + AppEngine application that lets users create online polls. I want to let the poll creator choose from a variety of themes for his poll. We will save the theme a poll creator chose on the server and whenever a poll respondent access the poll he will get the questions with the chosen theme. A theme for us means a set of 4-5 colors which we will use to style the poll page. Our client side application is a GWT application with styles set inline in UiBinder templates elements, for example: <ui:style> .header { background: color1; padding: 6px 6px; } .anothercssclass { background: color2; padding: 6px 6px; } </ui:style> Please suggest how we can set the color1 and color2 from the theme saved on server. Please note this is NOT a GWT module theme question.

  • mod_rewrite per-dir redirection returning a 400

    - by Eaterrust
    I moved my images directory to a different folder, and now I want to redirect all images requests from that folder to the new one. I do not have access to the main configuraion file, so I'm doing this in a .htaccess. I tried this, and it works:     RewriteCond %{REQUEST_URI} old_dir/.+.(jpg|png|gif)$     RewriteRule old_dir/(.+[^/]+..+)$ $1 [L,PT] But since they have permanently moved, I want to do a proper redirect, so I added the [R] flag, like this:      %{REQUEST_URI} old_dir/.+.(jpg|png|gif)$     RewriteRule old_dir/(.+[^/]+..+)$ $1 [L,PT,R] But the server gets confused, and returns a 400, so I looked at the log file, and this is what happens:     strip per-dir prefix: C:/wamp/www/natrazyle/old_dir/images/banner.jpg - old_dir/images/banner.jpg     applying pattern 'old_dir/(.+[^/]+..+)$' to uri 'old_dir/images/banner.jpg'     rewrite 'old_dir/images/banner.jpg' - 'images/banner.jpg'     add per-dir prefix: images/banner.jpg - C:/wamp/www/natrazyle/images/banner.jpg     explicitly forcing redirect with http://localhost/C:/wamp/www/natrazyle/images/banner.jpg As you can see, the full local path gets added after localhost I know I'm doing something wrong, I just can't figure it out myself. Any help would be greatly appreciated...

  • What's the syntax to import a class in a default package in Java?

    - by Lord Torgamus
    Possible Duplicate: How to access java-classes in the default-package? Is it possible to import a class in Java which is in the default package? If so, what is the syntax? For example, if you have package foo.bar; public class SomeClass { // ... in one file, you can write package baz.fonz; import foo.bar.SomeClass; public class AnotherClass { SomeClass sc = new SomeClass(); // ... in another file. But what if SomeClass.java does not contain a package declaration? How would you refer to SomeClass in AnotherClass?

  • Unable to make WMI connection from XP Pro machine to another (not in domain, same workgroup) in C#

    - by JCCyC
    I have two XP Pro SP3 machines. I disabled the firewall in both. The workgroup name is WORKGROUP. I have an administrator account with identical username/password in both. My code to connect is the following: ConnectionOptions options = new ConnectionOptions(); options.Username = myUsername; options.Password = myPassword; options.Authority = "ntdlmdomain:WORKGROUP"; // Commenting this or not makes no difference ManagementScope scope = new ManagementScope(String.Format("\\\\{0}\\{1}", hostname, Namespace), options); scope.Connect(); I always get a System.UnauthorizedAccessException with the text: "Access is denied. (Exception from HRESULT: 0x80070005 (E_ACCESSDENIED))" The above code works between two machines that are part of the same AD domain. What am I doing wrong?

  • Elegant way to distinct Path or Entry key

    - by sum1stolemyname
    I have an application loading CAD data (Custom format), either from the local filesystem specifing an absolute path to a drawing or from a database. Database access is realized through a library function taking the drawings identifier as a parameter. the identifiers have a format like ABC 01234T56-T, while my paths a typical windows Paths (eg x:\Data\cadfiles\cadfile001.bin). I would like to write a wrapper function Taking a String as an argument which can be either a path or an identifier which calls the appropriate functions to load my data. Like this: Function CadLoader(nameOrPath : String):TCadData; My Question: How can I elegantly decide wether my string is an idnetifier or a Path to a file? Use A regexp? Or just search for '\' and ':', which are not appearing in the Identifiers?

  • Accessing and encoding of properties files

    - by NoozNooz42
    I'm used to work with properties files, for example from Ant. Where I can simply reference the property file doing something like that: <property file="webapp_DO_NOT_COMMIT.properties"/> (the file is so named because our DVCS is configured as to never commit files containing "DO_NOT_COMMIT" to prevent committing credentials/passwords/etc.) Here's a very simple .properties file example: passwd=brokencleartextpassword Now I want to put some configuration in another, similar, properties file that I need to access from my Java code. How should I go about it? I also have another related question: is the character encoding of .properties file defined by any spec?

  • PHP find if file data is an image

    - by Christian Sciberras
    Imagine I have some file data in a variable $data. I need to determine whether it is an image or not. No need for details such as corrupt images etc. Firs thought would be getting the file mime type by looking at the magic number and then see whether "image" is in the mime type. No such luck, even if I have a "file extension to mime type" script, I don't have a reliable way to get mime from magic number. My next option was to have a reasonable list of image file magic numbers and consult them. However, it relatively difficult to find such magic numbers (gif for instance has different magic numbers, some of which could pretty rare - if memory serves me right). A better idea would be some linux program which can do this kind of thing. Any ideas? I'm running RHEL and PHP 5.3. I've got root access - ie able to install stuff if needed. - Chris.

  • Zend_Soap with attachments (server)

    - by Tom
    i'm trying to build a SOAP service with Zend_Soap. Everything is working great but the client needs the ability to send attachments to the service (not base64 encoded strings, as this service will be called multiple times a day with various file sizes so processing all that in memory is not possible. So I'd like to handle a normal SOAP attachment (DIME/MIME) with the SOAP server in Zend Framework however I'm unable to find documentation about it. Can I access it with $_FILES[] or any other way? Is it even possible in Zend_Soap (as there's not that much info available). SOAP is a must - so thanks for the advice but it has to be SOAP, not REST.

  • How to change the value of progressbar in C#?

    - by shekhar
    Hi, I want to add an progress bar into my C# based application. I would like to know what is the good way of updating its value at particular events? My problem is, I have single function in UI which does all the processing.This function in turn calls many more functions, creates objects, updates database, etc. (basically performs all the work) and returns values in an output file. I have access to that function only. So in this how to update the progressbar's value at the end of each step? What is the best practice for this kind of situation? What is the good way to keep UI logic and business logic seperate? I want to avoid writting progressbar related code in my library code. Please suggest some solution. Thanks and Regards,

  • Why is Zend Framework (Zend_Db_table) rejecting this SQL Query?

    - by Michael T. Smith
    I'm working on a simple JOIN of two tables (urls and companies). I am using this query call: print $this->_db->select()->from(array('u' => 'urls'), array('id', 'url', 'company_id')) ->join(array('c' => 'companies'), 'u.company_id = c.id'); which is out putting this query: SELECT `u`.`id`, `u`.`url`, `u`.`company_id`, `c`.* FROM `urls` AS `u` INNER JOIN `companies` AS `c` ON u.company_id = c.id Now, I'd prefer the c.* to not actually appear, but either way it doesn't matter. ZF dies with this error: SQLSTATE[42000]: Syntax error or access violation: 1064 You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '' at line 1" but I can run that query perfectly fine in my MySQL CLI. Any ideas how to fix up this query?

  • securing a webservice for use from a custom iphone app only

    - by mme
    I want to create an iphone application which consists of two parts: The app itself and a server side component. On a users request, the app sends data to the server which is to be handled by human operators. To prevent abuse from an iphone app user, the id of the iphone is sent along with the request, and the operators can blacklist pranksters to deny their iphone access to the service. So far so good. Now the problem is: Someone could easily discover the address of the serverside component, and write a script to send bogus requests, using multiple IP addresses etc. So my question is: how can I defend myself against this? Captchas to protect against scripted attacks or requiring the user to register himself are not an option for this particular application. If I had control of the download, I would associate a unique ID with each downloaded app, but obviously this is not an option with the appstore. What would be your approach to make the server side part more secure?

  • How to change a particular element of a C++ STL vector

None of the other vector methods seem to fit. I have used vector as I need random access functionality in my code (using l.at(i)).

  • Get a return value from a screen'd command

    - by AndyMac
    I'm running a process in a screen (on Ubuntu 13.10, if it matters). I can execute a command within that screen with: screen -p 0 -X eval 'stuff \"$command\"\015' I'm not 100% sure what this command is doing to begin with, though it's functioning correctly. The reason behind it is I'm running a Minecraft server (still) and this screens in to the correct screen, and throws the command on the running command line. So that's good, so far. But what I'd like is to be able to run this command with a return value. So for example, if I were to run a "list" command, it'd tell me how many people and who is online, but I need to capture that output and put it somewhere. Anyone know of a way to accomplish this? I can't tell the minecraft server command line to redirect the output somewhere else since it doesn't have direct command line access, so the only way I could do this would be to grab all output of the screen while I'm connected ... but I'm not sure if that's possible.

  • How can I treat a sequence value like a generated key?

    - by Jeff Knecht
    Here is my situation and my constraints: I am using Java 5, JDBC, and DB2 9.5 My database table contains a BIGINT value which represents the primary key. For various reasons that are too complicated to go into here, the way I insert records into the table is by executing an insert against a VIEW; an INSTEAD OF trigger retrieves the NEXT_VAL from a SEQUENCE and performs the INSERT into the target table. I can change the triggers, but I cannot change the underlying table or the general approach of inserting through the view. I want to retrieve the sequence value from JDBC as if it were a generated key. Question: How can I get access to the value pulled from the SEQUENCE. Is there some message I can fire within DB2 to float this sequence value back to the JDBC driver?
