How to get the gif file hosted by using the Http connection?


I have an application that downloads animation gif from a server by using the http connection. Here is the code I use to download the image.

try {

            httpConnection = (HttpConnection), Connector.READ_WRITE);            httpConnection.setRequestMethod(HttpConnection.GET);

            if (httpConnection.getResponseCode() == HttpConnection.HTTP_OK) {                DataInputStream dS = httpConnection.openDataInputStream();

                byte[] data = new byte[dS.available()];      ;

                gifImage = (GIFEncodedImage) EncodedImage.createEncodedImage(data, 0,data.length);

            } else {                throw new Exception("ResponseCode:" + httpConnection.getResponseCode());            }        } catch (Exception e) {                        gifImage = null;            e.printStackTrace();        }

the problem with this code is, when the gif file is 1175 bytes above, it does not load the gif.

example:-If the gif on the server is 1500 bytes, this code retrieves only 1175 bytes.

I think that the rest of the bytes are sent in a different package. But how to get them.

can someone please provide a code for buffering the inputstream?

any help is appreciated.



Hmm, nobody seems to know how to do, it seems. Here's how I did it.

            httpConnection = (HttpConnection), Connector.READ_WRITE);

            int responseCode = httpConnection.getResponseCode();
            if (responseCode == HttpConnection.HTTP_OK) {
                inputStream = httpConnection.openInputStream();
                ByteArrayOutputStream byteArrayOutputStream = new ByteArrayOutputStream();

                byte[] buffer = new byte[256];
                int len = 0, imageSize = 0;

                while (-1 != (len = {
                    imageSize += len;

                byte[] imageData = byteArrayOutputStream.toByteArray();

                gifImage = (GIFEncodedImage) EncodedImage.createEncodedImage(imageData, 0, imageSize);

  • HP 9470 m Ultrabook, Win8 - how to get the 3G connection?


    I got a Ultrabook 9470 m of work with Win7 installed. Everything works, cool, but I wated Win8 (64 bit) for my own stuff. So, I installed Win8 (dual-boot) for my use personal. Of course, I have no HP drives or whatever it is. -No worries, I found all drivers for Win8-64 in this site ok. And now everything is recognized correctly.

    But I don't know how to get the 3G card to connect. On Win7 HP connection manager takes care of that. But there is no connection manager for Win8. And google results only direct me to choose the network in the bar 'charm '. Great, but there are only available WiFis appear...

    ... --- ...

    Well, I finally got this resolved. -As usual, it'S just a driver issue, as always with Windows... I suppose that there is nothing new under the stars.

    In any case. Thanks for Cloud_Strider to point to the firmware upgrade. I did, but it alone did not help. BUT I don't know if it was still a part of the solution. So, thank you!

    Unfortunately, Ericsson or Navatel drivers broadband did the trick. -It's the only ounces available on the site of HP support for this laptop. = (Fortunately, I had (finally) look in Device Manager to see what drivers are installed. Seems that this braodband card is a HP un2430. Looking for these drivers for WIndows 8 on Google showed me finally good page on HP which she link to fresh (from March 2013) drivers for this card.

    After removing the old drivers (+ restart) and new (+ reset) installation, broadband is now available. I now write this with happiness through 3 G connection. =)

  • How to get the best connectivity WLan on Satellite U200

    I wonder if everyone is disappointed by the scope of the U200 wireless.

    I always find that my laptop shows 2 bars for their my BT hub (on the floor) when my eeepc located beside the laptop displays 5.

    I also found in other places that my partners laptop detects wireless networks much more that I do.

    I would prefer to explore the possibility of increasing my wireless connection before moving my BT hub to give me a better reception. being able to find the hub with my laptop wherever I am at home (like my partners)

    Anyone got any ideas please?

    OK, a few points of view but no ideas... I've now experimented with an external wireless adapter

    I have a toshiba satellite pro u200 with built in WiFi. I have also 2 adsl providers in the House (one is cancelled as soon as I am happy with the new - but I'll take the opportunity to experiment at the mo to try to resolve some problems)

    I have a wireless router in my office (the service of Virgin Media 2 MB - VM), the other is upstairs (BTHomehub 8 mb - BT)

    Using the built-in tosh Wireless adapt if I'm sitting 2 laptops side by side on my desk both pick up VM 100%. (tosh and eeepc)-c' is the case that the router slot in the Office!

    If I'm sitting the same 2 latops on my desk and get them to connect to BT, the onlys tosh gives 2 bars, the eeepc 100%. (by bars, I mean view available networks - see 5 bars to show the strength of connection)

    If I then plug an external 108Mbps Netgear WG111T Wireless USB 2.0 for the tosh connection adapter improves to 4 bars.

    can I do the built in WiFi on the tosh to improve things or am I better to use an external adapter. If I use the outside how tosh knows which adapter to use? as I have the switch wireless to the position we don't if this activate the integrated?

    Allow the pc show the network show the icon when connected and can see the speed to 54Mbps - whatever that means?

    shouldn't I expect to see 108 Mbit/s if that's what the external netgear is capable of?

    I'm a total beginner, and my problem is I can get a connection without wire only when I'm really close to my BT hub.
    My son has a laptop and gets a good connection anywhere in the House and even outside.

    He thinks I have a dodgy wireless adapter, this could be the problem?
    Can I fix it myself?

    Maybe download a new driver?
    Any suggestions would be much apreciated.



    Your ad is not really useful.
    I mean that there is no detail about your problem
    You should first check if the laptop supports the wireless network card.
    This can be done in the Device Manager.

    Usually the WLan card must appear in Manager devices-> network adapters.
    If it s are not it is that the WLan card is not built in or the driver WLan is not installed. If the WLan driver is not installed then you should see yellow exclamation (or unknown device).

    But if the wireless network adapter is listed correctly then you should check if the WLan notebooks have been enabled. In order to activate the WLan you have to press FN + F8 and you put the switch on IT until the small LED flash.

    Finally, to configure the WiFi connection (right name WLan, encryption settings, etc...)

    Hello world

    How to get the string (specified by row and column) of txt file with labview


    As far as I know, a text file has no column.  Be more specific.  Do you mean something like the 5th word on line 4, where the words are separated by a space, and lines are separated by a newline character?  You can read from the spreadsheet String function and set the delimiter to a space.  This will produce a 2D channels table.  Then use the table to index and give the line number and column number.

  • How to get the parameter values of a step type custom when I create file and adding a type of step seq

    I use lv 8.5 and teststand 4.0.

    I did a step type custom and recorded at the MyTypes.ini in pallets of type.

    I specified a default module by opening the properties of the custom step of *.ini type window, then I put some values of the parameters.

    T1) when I open teststand and I add the custom step type manaully in seq file, the labview module parameter values are represented.

    But, if to use file (create and add support prototype stage), the labview module parameter values has the default value.

    Using joint file, how to get the setting custom step type values I put in *.ini?

    Q2) each type of step are automatically by name through the use of LoadTypePaletteFilesEx. When I open teststand and I add the custom step type manaully in seq file, the module is loaded automatically. Inside the attachment, I use a prototype of charge and a fixed path where the module labview is to load the labview module.

    Can I load module automatically without using a prototype of charge or how can I get a dynamic path of type step?

    I solved Q1 for myself by using the mapping tab of the parameter within the configuration to the default module window.

    Everyone knows Q2?

  • How to get the host name of the physical computer inside a virtual machine until the user logs in Windows?

    I don't know if this is the right place to post this question, I develop software to support VMWare PCoIP and need to know how to get the host name of the physical machine (which manages the virtual machine and View Client) within a virtual machine before the user logs in Windows of the virtual machine.

    I understand there are two ways to read the host name, via the HKEY_CURRENT_USER\Volatile Environment registry and environment variables, but they are available once the user is connected. I need info before the user connects.

    Is there a VMware API that can be called or asked the host name?

    Thank you.

    Not on the broker, but there are the startup scripts to log on to the computer virtual itself:

    Note that these executed when a virtual desktop computer allocated connection, not to the point that the client connects - it is possible for the customer to not complete the connection (crash, cancel, network failure) and so any what solution you design must handle this.

    During the import of my camera or a file in Lightroom 5 my pictures are too exposed by 1-2 stops, while they are well exposed on the screen of the device. How to get the "right-exposed images on the screen?

    There is an option in your Lightroom preferences, under the general tab, "treat JPEG files next to raw in form of images". If you have this option is checked, then Lightroom will import and view your first two and JPEG files. You use the active D-lighting on your camera? If you are, you must disable this feature.

  • How to get the path of the vmdk to a VM stop file?

    Hi guys,.

    How to get the path of the vmdk to a VM stop file in ESX Server via the VIX API?

    I try to get it via the VixVM_ReadVariable() function. but it seems that this function requires that the virtual machine is power on.

    I don't want to go the virtual machine started, I just want to know if I can get the path of the vmdk file when a virtual machine is power off.

    Thanks in advance.

    Sorry, I don't have any samples.

    However, if you look at the layoutEx of the managed object VirtualMachine field, you will see that the VirtualMachineFileLayoutEx data object has a field "files" which should contain the paths of affected files.

    I hope that it should be able to help get started.
