  • vb.net program cannot connect to wampserver

    - by user225269
    I have a vb.net program that uses mysql as its database. And it works when the computer has wampservr installed. But the program gets an unhandled exception error when the computer where its running does not have a wampserver. The only thing that is installed in it is the mysql connector net. How do I make it work. I just want the two programs to access the same mysql database. I already opened port 20 by configuring firewall. Both in TCP and UDP. What do I do? Do I have to tweak the codes?

  • Drawing a path with a line in OpenLayers using JavaScript

    - by Andreas Grech
    I have seen the examples presented here of how to draw a line but the examples only show how to do it with the mouse, by clicking. What I want to do is draw the line manually using JavaScript given a list of Longitude and Latitude coordinates. The reason I cannot work on the source provided in the link above is because they are only calling activate on the feature, and then let the user point and click on the map. Has anyone ever drew a path on an OpenLayers map programatically? What I want to do is exactly this: http://openspace.ordnancesurvey.co.uk/openspace/example4.html, but without using OpenSpace.

  • Removing Divider Line from UISplitViewController

    - by tilomitra
    Guys, I know a similar question exists but the thread seems to be inactive, and I really would like this question to be answered. It's been annoying me for a few days now. I'm wondering how to remove the divider line between the Master and Detail view in the UISplitViewController. I know its possible to remove/hide/cover it up because I see some apps in the store without that line. I have tried setting backgroundColor to clearColour on my views but to no avail. So SO community, you're my only hope!

  • Writing to a new line of a file in Objective-C

    - by Kulpreet
    For some strange reason, the \n and \r escape sequences do not seem to be working in my code. I want to write each NSString on a new line of the file, but it just appends it the last string on one line. Here's the code: for (Entry *entry in self.entries) { NSString *path = @"/Users/me/File.txt"; NSString *string = (@"%@\r\n", [entry thisEntry]); NSFileHandle *fh = [NSFileHandle fileHandleForWritingAtPath:path]; [fh seekToEndOfFile]; [fh writeData:[string dataUsingEncoding:NSUnicodeStringEncoding]]; [fh closeFile]; } Am I doing something wrong? Forgive me as I am new to Objective-C.

  • Is url.openStream harmful?

    - by Casebash
    I was using the java.net.URL.openStream() method to retrieve content from the server. I recently ran into an issue where the HTTP Response code indicated an error, but instead of throwing an exception, the stream still was read anyway. This caused the error to appear much later in the execution and proved to be a red herring. As far as I can see, when you have opened a stream using this method, there is no way to check the HTTP response code. The only way I could find to handle this properly was to use code such as: HttpURLConnection conn=(HttpURLConnection) url.openConnection() if(conn.getResponseCode()!=HttpStatus.SC_OK) //Raise Exception; InputStream in=conn.getInputStream() So do you agree? Is it possible to use openStream safely, or is it a method that should be avoided at all costs. It is worth noting that Sun uses the method in their tutorial code for reading directly from a URL. Then again, the code throws Exception so it isn't exactly a bastion of good coding practices.

  • Makefile error: Unexpected end of line seen

    - by Winston C. Yang
    Trying to install Git, I ran configure and make, but got the following error message: make: Fatal error in reader: Makefile, line 221: Unexpected end of line seen The Makefile looks like: 218: GIT-VERSION-FILE: FORCE 219: @$(SHELL_PATH) ./GIT-VERSION-GEN 220: -include GIT-VERSION-FILE 221: 222: uname_S := $(shell sh -c 'uname -s 2>/dev/null øø echo not') What's causing the error? The following information may or may not be relevant: I tried to install Git 1.7.0.3 on SunOS 5.9 (Solaris 9) in a directory in my account. The gcc version is 3.4.2 (older then the version of 3.4.6 stated by sunfreeware.com). I don't have root privileges.

  • linux: disable using loopback and send data via wire between 2 eth cards of one comp

    - by osgx
    Hello I have a comp with 2 eth cards, connected with patch-cord (direct eth. cable from 1st to 2nd). The linux is installed, I want to send data from 1st network card to 2nd. And I want to force the packet to pass via cable. I can set up any ip on cards. With ping I get counters on cards constant. Is it possible with tcp/ip sockets? PS. I need to write a program. which will send packets via eth, so stackoverflow-related question. There can be some OS-dependent way, they will help me too

  • How to check server connection is available or not in android

    - by Kalai Selvan.G
    Testing of Network Connection can be done by following method: public boolean isNetworkAvailable() { ConnectivityManager cm = (ConnectivityManager) getSystemService(Context.CONNECTIVITY_SERVICE); NetworkInfo networkInfo = cm.getActiveNetworkInfo(); if (networkInfo != null && networkInfo.isConnected()) { return true; } return false; } But i don't know how to check the server connection.I had followed this method public boolean isConnectedToServer(String url, long timeout) { try{ URL myUrl = new URL(url); URLConnection connection = myUrl.openConnection(); connection.setConnectTimetout(timeout); connection.connect(); return true; } catch (Exception e) { // Handle your exceptions return false; } } it doesn't works....Any Ideas Guys!!

  • How can you change Network settings (IP Address, DNS, WINS, Host Name) with code in C#

    - by rathkopf
    I am developing a wizard for a machine that is to be used as a backup of other machines. When it replaces an existing machine, it needs to set its IP address, DNS, WINS, and host name to match the machine being replaced. Is there a library in .net (C#) which allows me to do this programatically? There are multiple NICs, each which need to be set individually. EDIT Thannk you TimothyP for your example. It got me moving on the right track and the quick reply was awesome. Thanks balexandre. Your code is perfect. I was in a rush and had already adapted the example TimothyP linked to, but I would have loved to have had your code sooner. I've also developed a routine using similar techniques for changing the computer name. I'll post it in the future so subscribe to this questions RSS feed if you want to be informed of the update. I may get it up later today or on Monday after a bit of cleanup.

  • How do I check if output stream of a socket is closed?

    - by Roman
    I have this code: public void post(String message) { output.close(); final String mess = message; (new Thread() { public void run() { while (true) { try { output.println(mess); System.out.println("The following message was successfully sent:"); System.out.println(mess); break; } catch (NullPointerException e) { try {Thread.sleep(1000);} catch (InterruptedException ie) {} } } } }).start(); } As you can see I close the socket in the very beginning of the code and then try to use it to send some information to another computer. The program writes me "The following message was successfully sent". It means that the NullPointerException was not thrown. So, does Java throw no exception if it tries to use a closed output stream of a socket? Is there a way to check if a socket is closed or opened? ADDED I initialize the socket in the following way: clientSideSocket = new Socket(hostname,port); PrintWriter out = new PrintWriter(clientSideSocket.getOutputStream(), true); browser.output = out;

  • Multimedia files written over WAN are getting truncated

    - by Dean
    I use the windows Multimedia API to create .wav files. 1. Open file with mmsioOpen 2. Creates WAVE,frm and data chunks using mmioCreateChunk 3. Write audio data using mmioWrite 4. Ascend out of the chunks using mmioAscend 5. Close file using mmioClose The file is being written into a temporary location, so after it has been closed it gets copied to another location using the CopyFile. This program is written in C++ and works great until the file it is writing resides over a WAN in a different city or country. The end result is a wav file that should be 20-30 seconds long ends up being 4 secodns long. It is always the last bit that is missing, so when you play it back it just stops before then of the recording. I initially thought that maybe I was copying the file too soon so as a test I put in a pause of 30 seconds after closing the file using Sleep(30000), but this made no difference to either it being truncated or by how much. I have modified the program to write to a file in parrallel using CreateFile and WriteFile, and the result is the same, so it is not an issue specifically with the mmio API's. Does anyone have any ideas why this is happening and if there is a work-around to it? I suspect that I may end up having the temporary location on the local drive, but this is quite a big change to the application as well as existing deployments. thanks for everyones time Dean

  • How to debug packet loss ?

    - by Gene Vincent
    I wrote a C++ application (running on Linux) that serves an RTP stream of about 400 kbps. To most destinations this works fine, but some destinations expericence packet loss. The problematic destinations seem to have a slower connection in common, but it should be plenty fast enough for the stream I'm sending. Since these destinations are able to receive similar RTP streams for other applications without packet loss, my application might be at fault. I already verified a few things: - in a tcpdump, I see all RTP packets going out on the sending machine - there is a UDP send buffer in place (I tried sizes between 64KB and 300KB) - the RTP packets mostly stay below 1400 bytes to avoid fragmentation What can a sending application do to minimize the possibility of packet loss and what would be the best way to debug such a situation ?

  • bash tips needed for understanding how to escape characters in command-line

    - by Jesper Rønn-Jensen
    My knowledge of commandline bash is missing on a particular area: I constantly forget how to properly escape characters. Today I wanted to echo this string into a file: #!/bin/env bash python -m SimpleHTTPServer echo "#!/bin/env bash\npython -m SimpleHTTPServer" server.sh && chmod +x server.sh -bash: !/bin/env: event not found That's right: Remember to escape ! or bash will think it's a special bash event command. But I can't get the escaping right! \! yields \! in the echoed string, and so does \\!. Furthermore, \n will not translate to a line break. Do you have some general tips that makes it easier for me to understand escaping rules? To be very precise, I'll accept an answer which tells me which characters I should escape on the bash command line? Including how to correctly output newline and exclamation mark in my example.

  • Unit Testing a Java Chat Application

    - by Epitaph
    I have developed a basic Chat application in Java. It consists of a server and multiple client. The server continually monitors for incoming messages and broadcasts them to all the clients. The client is made up of a Swing GUI with a text area (for messages sent by the server and other clients), a text field (to send Text messages) and a button (SEND). The client also continually monitors for incoming messages from other clients (via the Server). This is achieved with Threads and Event Listeners and the application works as expected. But, how do I go about unit testing my chat application? As the methods involve establishing a connection with the server and sending/receiving messages from the server, I am not sure if these methods should be unit tested. As per my understanding, Unit Testing shouldn't be done for tasks like connecting to a database or network. The few test cases that I could come up with are: 1) The max limit of the text field 2) Client can connect to the Server 3) Server can connect to the Client 4) Client can send message 5) Client can receive message 6) Server can send message 7) Server can receive message 8) Server can accept connections from multiple clients But, since most of the above methods involve some kind of network communication, I cannot perform unit testing. How should I go about unit testing my chat application?

  • Amazon EC2 - network issues

    - by Algorist
    Hi, We are launching hadoop cluster on amazon ec2 and recently we are having network issues like master unable to connect to slave. We thought the reason is due to amazon throttling the network connections over a limit. So, we tried to establish a connection after a random delay from each slave node. But, that didn't help. Are there any other suggestions? Thank you Bala

  • OAuth request token for an installed application

    - by Andres
    Hi all I'm trying to use/understand Google request token mechanism. I intend to use it for an application I've start to develop to access Orkut data using OpenSocial API. I read this document that explains the steps to obtain a token for an installed application. This document tells you to use the OAuthGetRequestToken method from Google OAuth API to acquire a request token . Accessing the manual of this function (available here). But the parameter oauth_consumer_key, which is required, asks for the "Domain identifying the third-party web application", but I don,t have a domain, it is an installed application. So my question is, what should I put in this parameter in that case? I'm using oauth_playground to run my tests. Thx
