• how can we apply client side validation on fileupload control in ASP.NET to check filename contain s

  - by subodh

  I am working on ASP.NET3.5 platform. I have used a file upload control and a asp button to upload a file. Whenever i try to upload a file which contain special characterlike (file#&%.txt) it show crash and give the messeage Server Error in 'myapplication' Application. A potentially dangerous Request.Files value was detected from the client (filename="...\New Text &#.txt"). Description: Request Validation has detected a potentially dangerous client input value, and processing of the request has been aborted. This value may indicate an attempt to compromise the security of your application, such as a cross-site scripting attack. You can disable request validation by setting validateRequest=false in the Page directive or in the configuration section. However, it is strongly recommended that your application explicitly check all inputs in this case. Exception Details: System.Web.HttpRequestValidationException: A potentially dangerous Request.Files value was detected from the client (filename="...\New Text &#.txt"). Source Error: An unhandled exception was generated during the execution of the current web request. Information regarding the origin and location of the exception can be identified using the exception stack trace below. how can i prevent this crash using javascript at client side?

• Store the cache data locally

  - by Lu Lu

  Hello, I develops a C# Winform application, it is a client and connect to web service to get data. The data returned by webservice is a DataTable. Client will display it on a DataGridView. My problem is that: Client will take more time to get all data from server (web service is not local with client). So I must to use a thread to get data. This is my model: Client create a thread to get data - thread complete and send event to client - client display data on datagridview on a form. However, when user closes the form, user can open this form in another time, and client must get data again. This solution will cause the client slowly. So, I think about a cached data: Client <---get/add/edit/delete--- Cached Data ---get/add/edit/delete---Server (web service) Please give me some suggestions. Example: cached data should be developed in another application which is same host with client? Or cached data is running in client. Please give me some techniques to implement this solution. If having any examples, please give me. Thanks.

• What we have to measure for measuring server performance If we can't measure the server processing time from client side?

  - by AsadYarKhan

  If we can not measure the server processing time from client side then which attributes will be good to measure in client side for measuring server side performance and What attributes are important ? I know we can get the server response time, latency and Throughput etc,but how do we understand/interpret the result of server side from these attrubutes. How can we analyse that whether my code is taking lots of time,whether Web Server, whether it is because of Server Machine(H/W).how would i know that which thing needs to be upgrade or improve.Please tell me any article or any book something that I need to study or explain here If you can so I can interpret the result of server side using these attributes response time, latency and throughput.You can tell other performance attribute if I need to understand the server result.

• How do I make the manifest available during a Maven/Surefire unittest run "mvn test" ?

  - by Ernst de Haan

  How do I make the manifest available during a Maven/Surefire unittest run "mvn test" ? I have an open-source project that I am converting from Ant to Maven, including its unit tests. Here's the project source repository with the Maven project: http://github.com/znerd/logdoc My question pertains to the primary module, called "base". This module has a unit test that tests the behaviour of the static method getVersion() in the class org.znerd.logdoc.Library. This method returns: Library.class.getPackage().getImplementationVersion() The getImplementationVersion() method returns a value of a setting in the manifest file. So far, so good. I have tested this in the past and it works well, as long as the manifest is indeed available on the classpath at the path META-INF/MANIFEST.MF (either on the file system or inside a JAR file). Now my challenge is that the manifest file is not available when I run the unit tests: mvn test Surefire runs the unit tests, but my unit test fails with a mesage indicating that Library.getVersion() returned null. When I want to check the JAR, I find that it has not even been generated. Maven/Surefire runs the unit tests against the classes, before the resources are added to the classpath. So can I either run the unit tests against the JAR (implicitly requiring the JAR to be generated first) or can I make sure the resources (including the manifest file) are generated/copied under target/classes before the unit tests are run? Note that I use Maven 2.2.0, Java 1.6.0_17 on Mac OS X 10.6.2, with JUnit 4.8.1.

• MySQL hangs if connection comes from outside the LAN

  - by Subito

  I have a MySQL Server operating just fine if I access him from his local LAN (192.168.100.0/24). If I try to access hin from another LAN (192.168.113.0/24 in this case) it hangs for a really long time before delivering the result. SHOW PROCESSLIST; shows this process in Sleep, State empty.

• Is there an FTP client for Windows 7 with a text-based UI? (not text-prompt based, like ftp.exe)

  - by Alan B

  Is there such as thing as a text-mode FTP client for Windows 7 ? By 'text-mode' I mean one that runs in a CMD.EXE window as opposed to a Windows GUI application. It also needs to be something along the lines of FileZilla, i.e. menu-driven as opposed to command-entry clients like NcFTP or indeed the built-in one. edit: To avoid confusion, what I mean is an application similar to that pictured (ZTreeWin File Manager), which runs from CMD.EXE and uses text characters for its UI, within the CMD.EXE window. The built-in FTP client, and things like NcFTP offer a prompt at which you issue commands. That's not what I'm looking for.

• git changes modification time of files

  - by tanascius

  In the GitFaq I can read, that Git sets the current time as the timestamp on every file it modifies, but only those. However, I tried this command sequence (EDIT: added complete command sequence) $ git init test && cd test Initialized empty Git repository in d:/test/.git/ exxxxxxx@wxxxxxxx /d/test (master) $ touch filea fileb exxxxxxx@wxxxxxxx /d/test (master) $ git add . exxxxxxx@wxxxxxxx /d/test (master) $ git commit -m "first commit" [master (root-commit) fcaf171] first commit 0 files changed, 0 insertions(+), 0 deletions(-) create mode 100644 filea create mode 100644 fileb exxxxxxx@wxxxxxxx /d/test (master) $ ls -l > filea exxxxxxx@wxxxxxxx /d/test (master) $ touch fileb -t 200912301000 exxxxxxx@wxxxxxxx /d/test (master) $ ls -l total 1 -rw-r--r-- 1 exxxxxxx Administ 132 Feb 12 18:36 filea -rw-r--r-- 1 exxxxxxx Administ 0 Dec 30 10:00 fileb exxxxxxx@wxxxxxxx /d/test (master) $ git status -a warning: LF will be replaced by CRLF in filea # On branch master warning: LF will be replaced by CRLF in filea # Changes to be committed: # (use "git reset HEAD <file>..." to unstage) # # modified: filea # exxxxxxx@wxxxxxxx /d/test (master) $ git checkout . exxxxxxx@wxxxxxxx /d/test (master) $ ls -l total 0 -rw-r--r-- 1 exxxxxxx Administ 0 Feb 12 18:36 filea -rw-r--r-- 1 exxxxxxx Administ 0 Feb 12 18:36 fileb Now my question: Why did git change the timestamp of file fileb? I'd expect the timestamp to be unchanged. Are my commands causing a problem? Maybe it is possible to do something like a git checkout . --modified instead? I am using git version 1.6.5.1.1367.gcd48 under mingw32/windows xp.

• How do I send a client-event asynchronously to a GtkWidget?

  - by fret

  I'm trying to send and receive a client-event using a GtkWidget on the win32 platform. The sending code looks like this: GtkWidget *Wnd; GdkNativeWindow Hnd = #ifdef WIN32 GDK_WINDOW_HWND(Wnd->window); #else GDK_WINDOW_XWINDOW(Wnd->window); #endif GdkEvent *Event = gdk_event_new(GDK_CLIENT_EVENT); // fill out Event params gdk_event_send_client_message(Event, Hnd); Receiving code looks like this: static gboolean MyClientEvent(GtkWidget *widget, GdkEventClient *ev, MyWnd *Wnd) { // breakpoint here... return TRUE; } GtkWidget *Wnd = gtk_window_new(GTK_WINDOW_TOPLEVEL); g_signal_connect( G_OBJECT(Wnd), "client-event", G_CALLBACK(MyClientEvent), this); gtk_widget_add_events(Wnd, GDK_ALL_EVENTS_MASK); I used Spy++ to see the message getting sent, so I know the sending side is ok. The receiving side however doesn't get the client-event. I was expecting my breakpoint in the callback to trigger... but it doesn't. I'm not even sure if a GtkWindow can receive a client-event... from past experience on X11 I thought it was pretty much the same as any other GtkWidget in that respect. Maybe on the win32 platform it's kinda different. But still I'd like to be able to get this working. I would like this to work with asynchronously, and in a thread-safe fashion, so that I can send events from worker threads up to the GUI thread.

• what are the vulnerabilities installing openvpn client on a customer's unattended server?

  - by senorsmile

  We run Pfsense as our primary firewall. We also have OpenVPN server running on that box to allow us to remotely connect to our network. My question is: if we have a customer's mostly unattended server that we want to access remotely, what security vulnerabilities are there to installing openvpn on the customer's server as a client connecting to our network. Presumably, we would want to limit/restrict that server's access to the rest of our network. How do we lock openvpn down and are there ways to detect abnormal activity coming from an openvpn client?

• How can I unit test a PHP class method that executes a command-line program?

  - by acoulton

  For a PHP application I'm developing, I need to read the current git revision SHA which of course I can get easily by using shell_exec or backticks to execute the git command line client. I have obviously put this call into a method of its very own, so that I can easily isolate and mock this for the rest of my unit tests. So my class looks a bit like this: class Task_Bundle { public function execute() { // Do things $revision = $this->git_sha(); // Do more things } protected function git_sha() { return `git rev-parse --short HEAD`; } } Of course, although I can test most of the class by mocking git_sha, I'm struggling to see how to test the actual git_sha() method because I don't see a way to create a known state for it. I don't think there's any real value in a unit test that also calls git rev-parse to compare the results? I was wondering about at least asserting that the command had been run, but I can't see any way to get a history of shell commands executed by PHP - even if I specify that PHP should use BASH rather than SH the history list comes up empty, I presume because the separate backticks executions are separate terminal sessions. I'd love to hear any suggestions for how I might test this, or is it OK to just leave that method untested and be careful with it when the app is being maintained in future?

• Should I close sockets from both ends?

  - by Roman

  I have the following problem. My client program monitor for availability of server in the local network (using Bonjour, but it does not rally mater). As soon as a server is "noticed" by the client application, the client tries to create a socket: Socket(serverIP,serverPort);. At some point the client can loose the server (Bonjour says that server is not visible in the network anymore). So, the client decide to close the socket, because it is not valid anymore. At some moment the server appears again. So, the client tries to create a new socket associated with this server. But! The server can refuse to create this socket since it (server) has already a socket associated with the client IP and client port. It happens because the socket was closed by the client, not by the server. Can it happen? And if it is the case, how this problem can be solved? Well, I understand that it is unlikely that the client will try to connect to the server from the same port (client port), since client selects its ports randomly. But it still can happen (just by chance). Right?

• Creating C++ client app for some abstract windows server - how to manage TCP connection to server speed?

  - by Kabumbus

  So we have some server with some address port and ip. we are developing that server so we can implement on it what ever we need for help. What are standard/best practices for data transfer speed management between C++ windows client app and server (C++)? My main point is in how to get how much data can be uploaded/downloaded from/to client via his low speed network to my relatively super fast server. (I need it for set up of his live stream Audio/Video bit rate) My try on explaining number 3. We do not care how fast is our server. It is always faster than needed. We care about client tyring to stream out to our server his media. he streams encoded (via ffmpeg) live video data to our server. But he has say ADSL with 500kb/s of outgoing traffic. Also he uses some ICQ or what so ever so he has less than 500 kb/s per second. And he wants to stream live video! So we need to set up our ffmpeg to encode video with respect to the bit rate user can provide. We develop server side and client side. We need a way of finding out how much user can upload per second currently (so value can change dynamically over time)

• Java sockets: multiple client threads on same port on same machine?

  - by espcorrupt

  I am new to Socket programming in Java and was trying to understand if the below code is not a wrong thing to do. My question is: Can I have multiple clients on each thread trying to connect to a server instance in the same program and expect the server to read and write data with isolation between clients" public class Client extends Thread { ... void run() { Socket socket = new Socket("localhost", 1234); doIO(socket); } } public class Server extends Thread { ... void run() { // serverSocket on "localhost", 1234 Socket clientSock = serverSocket.accept(); executor.execute(new ClientWorker(clientSock)); } } Now can I have multiple Client instances on different threads trying to connect on the same port of the current machine? For example, Server s = new Server("localhost", 1234); s.start(); Client[] c = new Client[10]; for (int i = 0; i < c.length; ++i) { c.start(); }

• Why can I not access any file or directory created by PHP from FTP-client?

  - by user43053

  Hello there, If I create a directory with mkdir(), or create a file with fopen(), file_put_contents() or SimpleXMLElement::asXML(), I am unable to access the file with my FTP-client or c-Panel File Manager. If I try to delete or edit them, I get errors. Dreamweaver suggests it is a permission problem or a network or filesystem fault (but I've set the permissions with chmod() to 0777, and when I check the cPanel, it confirms chmod 777. I also tried to use fileowner() and the function returns int(99), the same owner as those files that I could access with my FTP-client. It seems files and directories created with PHP can only be modified or be deleted with PHP. I thought this must be a server setup related issue, so I write it here. I am on a shared server, and I have no idea about setting up servers. Thank you for your time. Kind regards Marius

• is it better to test if a function is needed inside or outside of it?

  - by b0x0rz

  what is the best practice? call a function then return if you test for something, or test for something then call? i prefer the test inside of function because it makes an easier viewing of what functions are called. for example: protected void Application_BeginRequest(object sender, EventArgs e) { this.FixURLCosmetics(); } and private void FixURLCosmetics() { HttpContext context = HttpContext.Current; if (!context.Request.HttpMethod.ToString().Equals("GET", StringComparison.OrdinalIgnoreCase)) { // if not a GET method cancel url cosmetics return; }; string url = context.Request.RawUrl.ToString(); bool doRedirect = false; // remove > default.aspx if (url.EndsWith("/default.aspx", StringComparison.OrdinalIgnoreCase)) { url = url.Substring(0, url.Length - 12); doRedirect = true; } // remove > www if (url.Contains("//www")) { url = url.Replace("//www", "//"); doRedirect = true; } // redirect if necessary if (doRedirect) { context.Response.Redirect(url); } } is this good: if (!context.Request.HttpMethod.ToString().Equals("GET", StringComparison.OrdinalIgnoreCase)) { // if not a GET method cancel url cosmetics return; }; or should that test be done in Application_BeginRequest? what is better? thnx

• Is anyone working on an encfs client for windows?

  - by snth

  I've been looking into encfs as a solution to encrypt my personal data. However I want to access this data both on Linux and Windows on different machines (synced through Dropbox). So far all Google searches have brought up pages which specify that there is no Windows client that reads encfs. Therefore my question is: is anyone working on a Windows client for encfs? It would be really useful if someone was and it seems to be a common enough issue raised that I have a glimmer of hope that someone might be working on it.

• How to setup Apache 2.2 (prefork) with mod_fcgid to test a C++ application?

  - by skyeagle

  I have written my first fastcgi application (C/C++), and I need to test it to ensure that it is behaving the way I expect it to. I have searched for examples on setting up Apache 2.2. with mod_fcgid, but all of teh tutorials etc I have seen, relate to PHP, Python, Perl etc. Is anyone aware of a resource that shows how I may setup Apache to use mod_fcgid (NOT mod_fastcgi) to test my binary? If no online resource is available (I'd be surprised), then could someone please point out the steps required to do the testing?

• Stop ssh client from offering all the public keys it can find?

  - by Rory McCann

  Like most sysadmins I use openssh all the time. I have about a dozen ssh keys, I like to have a different ssh key for each host. However this causes a problem when I am connecting to a host for the first time, and all I have is a password. I want to just connect to the host using a password, no ssh key in this case. However the ssh client will offer all the public keys in my ~/.ssh/ (I know this from looking at the output of ssh -v). Since I have so many, I will get disconnected for too many authentication failures. Is there some way to tell my ssh client to not offer all the ssh keys?

• Cannot make a static reference to the non-static type MyRunnable

  - by kaiwii ho

  Here is the whole code : import java.util.ArrayList; public class Test{ ThreadLocal<ArrayList<E>>arraylist=new ThreadLocal<ArrayList<E>>(){ @Override protected ArrayList<E> initialValue() { // TODO Auto-generated method stub //return super.initialValue(); ArrayList<E>arraylist=new ArrayList<E>(); for(int i=0;i<=20;i++) arraylist.add((E) new Integer(i)); return arraylist; } }; class MyRunnable implements Runnable{ private Test mytest; public MyRunnable(Test test){ mytest=test; // TODO Auto-generated constructor stub } @Override public void run() { System.out.println("before"+mytest.arraylist.toString()); ArrayList<E>myarraylist=(ArrayList<E>) mytest.arraylist.get(); myarraylist.add((E) new Double(Math.random())); mytest.arraylist.set(myarraylist); System.out.println("after"+mytest.arraylist.toString()); } // TODO Auto-generated method stub } public static void main(String[] args){ Test test=new Test<Double>(); System.out.println(test.arraylist.toString()); new Thread(new MyRunnable(test)).start(); new Thread(new MyRunnable(test)).start(); System.out.println(arraylist.toString()); } } my questions are: 1\ why the new Thread(new MyRunnable(test)).start(); cause the error: Cannot make a static reference to the non-static type MyRunnable ? 2\ what is the static reference refer to right here? thx in advanced

• how to handle db concurrency in client-server application in C#?

  - by RAJ K

  I am developing an application in C# WPF which will have Client-Server architecture (Client will do products sales billing). I am novice in this area and I asked this question to start my development process. Click here to view question. So, ultimately I have selected MySQl, WCf & WPF. Now I have one silly question. Do i need to handle DB concurrency explicitly in my application (like 3 clients inserting data same time) or MySQl will handle this without any conflict? To accomplish my project i thought, I will create a service in WCf which will do DB queries from client application. Do you have any suggestion to improve my application performance.

• Can I use WCF NET.TCP Protocol from Silverlight 4 for a public website ?

  - by pixel3cs

  Does anyone know if the new NET.TCP feature of Silverlight 4 can be used for public websites ? From what I know, in the Silverlight 4 Beta they announced that WCF NET.TCP can only be used for intranet applications. The reason I am asking this is because I want to recode my Silverlight multiplayer chess game (build with SL 3 Sockets support) based on the new SL 4 WCF TCP communication protocol. My Socket implementation is build from scratch and have big issues with thread safe and few unsolvable bugs from my side. I am sure that SL 4 team did a great job and they simplified all hard part for me, letting us, developers, concentrate more on the game code instead on underlying communication layers.

• Would using a MemoryMappedFile for IPC across AppDomains be faster than WCF/named pipes?

  - by Morten Mertner

  Context: I am loading and executing untrusted code in a separate AppDomain and am currently communicating between the two using WCF (using named pipes as the underlying transport). I am exchanging relatively simple object graphs using a reasonably coarse-grained API, but would like to use a more fine-grained API if it does not cost me performance-wise. I've noticed that 4.0 adds a MemoryMappedFile class (which doesn't need a physical file, so could be entirely memory based). What kind of performance gains could I expect to see (if any) by using this new class? I know that it would take some "infrastructure code" to get the request/response behavior of WCF, but for now I'm only interested in the performance difference.
