Receiving data using the device RFCOMM Protocol activate bluetooth

• I have a problem when you try to receive data using the socket connection.

  Hello

  I created a socket connection between a pc (sever, win32) and a blackberry (client) and I have only two questions:

  -When I send a string to the sever I get the unexpected result, I doubt if it's a problem of encoding between platforms.

  -When I try to receive data, (an array of char as a string object), the customer demand freeze (drawing and management of events, so basically the main UI thread), even if I did all the stuff of connection in a separate thread, until I have shut down the server and also no data is received.

  I left the codes below and would assess any response from you.

  C++, win32 console application:

  SOCKET _Socket;

  int _tmain (int argc, _TCHAR * argv)

  {

  If (start_sever (_socket)) {}

  char r_msg [26];

  recv (_socket, r_msg, 26, 0);

  std::cout< "receive="" :="" "="">< r_msg=""><>

  char * s_msg customer = 'welcome ';

  Send (_socket, szMessage, strlen (S_MSG), 0);

  std::cout< "send="" :="" "="">< s_msg=""><>

  Sleep (500);

  Shutdown (_socket, SD_SEND);

  closesocket (_socket);

  WSACleanup();

  } else {}

  std::cout< "cannot="" initialize="">< std::endl="">

  }

  System ("pause");

  return 0;

  }

  BOOL start_sever (socket) {}

  WSADATA WsaDat;

  If (WSAStartup (MAKEWORD (2.2) & WsaDat)! = 0)

  {

  std::cout<"WSA initialization="">

  WSACleanup();

  System ("pause");

  Returns false;

  }

  Socket = socket (AF_INET, SOCK_STREAM, IPPROTO_TCP);

  if(Socket==INVALID_SOCKET)

  {

  std::cout<"Socket creation="">

  WSACleanup();

  System ("pause");

  Returns false;

  }

  SOCKADDR_IN serverInf;

  serverInf.sin_family = AF_INET;

  serverInf.sin_addr.s_addr = INADDR_ANY;

  serverInf.sin_port = htons (8888);

  If (bind (Socket,(sockaddr*) (& serverInf), sizeof (serverInf)) == SOCKET_ERROR)

  {

  std::cout<"Unable to="" bind="">

  WSACleanup();

  System ("pause");

  Returns false;

  }

  Thanks for your help.

  You treat on the thread of events.

  You have the following code:

  UiApplication.getUiApplication () .invokeLater (new Runnable() {}

  public void run() {}

  try {

  open_connection();

  .....

  Now invokeLater essentially tells the operating system that the associated executable must be run on the event Thread.  You need start a separate Thread.  Extend this Thread, add your code in the run() method, and then start the Thread with start(). (not run()).  Then you must run the networking of processing on a separate Thread.

  This will cause you problems updating the user interface.  Take a look at this help:

  http://supportforums.BlackBerry.com/T5/Java-development/update-a-screen-on-the-main-event-thread/TA-...

  Printing, this means that invokelater a separate Thread is a common misconception.  I recommend you to look at this:

  http://supportforums.BlackBerry.com/T5/Java-development/what-is-the-event-thread/Ta-p/446865

  In addition, I recommend that you take a look at the socketDemo which must be included as a sample-, otherwise you can find it on github:

  Hi a. Cook,

  (1) how long have you been faced with this problem?

  (2) is limited to any specific USB device?

  This problem may occur if there are handles open with all the files in the USB (Universal Serial Bus) mass storage device are in use by another program.

  Method 1:

  (a) Download Process Explorer from the link below

  http://TechNet.Microsoft.com/en-us/Sysinternals/bb896653

  (b) click on search, find handle or DLL (Dynamic Link Library) in the tool menu.

  (c) type the drive letter of the USB device in the handle or DLL substring text box and press the search button.

  (d) find the process and its PID (process identifier) in the following box.

  (e) with a view to the processes of the system tree, look for the process according to the dialog box find handle or DLL.

  (f) press Ctrl + H to display the handles in the view in the lower pane.

  (g) find the file according to the drive letter and right click, choose Manage close.

• How to use the device as a simulator.

  Hi all

  Can someone tell me how to use the device (with my development pc) as Simulator.

  Whenever I need to check the appilcation in device of signed files .cod that is compiled in the Simulator.

  Because I got the outofmemory error in the device rather than simulator.

     

  Thus, any solution which signed without how can I check my direct request to the device itself. Any setting in preferences or etc...
  

  Thank you

  Tejas

          
  

  The only way you should not sign the cod is if no controlled classes/interfaces are used. The easy way to find out is to open the SignatureTool and see if your application requires signature. Otherwise this says icefrost1 's good enough solution.

• Issue while loading data using the file Rules Essbase

  Hi all

  I am facing problem while loading data using the Rules file. In the rules file, I rejected several members in two areas (two dimensions). Now if I load the data using the rules file I'm getting errors for all members in the dataload.err file. If I reject mutiple members of a single field, the data load without settling errors in the dataload.err file.

  I want to know how rmany members of several fields of ejection for loading data using the file Rules Essbase? Is it possible?

  Okay, okay... I think that you must assign Global Select / reject Boolean in the parameters of loading data as 'Or':

• Why the message time / date uses the original sent time?

  Hello
  I noticed that emails that are delayed come using the time sent initially, rather than when they reach my server. It is unusual, because it may end with a 'new' message finish well down the list of the other messages sent more recently.
  What's the intended operation?

  Note the following header: This shows up in my Inbox based on time 02:57 was created, even if he won't even let the original that much server later.

  Of workaround applies only to an IMAP account, where only the headers are downloaded. Quite rare really that is not the default.

  The date of receipt is available in the pane always, just right clicking on the headers and select it from the list is all that is needed. Sort by the order received however denies all dates and maintains strict order of the received mail. However, all these things are on the view > menu sort order, including consolidation of beloved today yesterday last week so the sort of Outlook users.

  Curiously, I find everything on Outlook without exchange awkward and somewhat limited, but it's an exchange client really not a customer of general e-mail in my opinion.

• standalone application for the acquisition of data using the NI DAQ card

  I did a stand-alone application in labview GUI for data acquisition and processing of the signal. If I have to run this application in any other computer which should be all installed software other than the labview runtime engine... CD DEVICE DRIVERS OR alone must be installed or do I have to install any other software of data acquisition using the data acquisition card OR?

  Thanks and greetings

  You need only the racing of the engine, the device for the device drivers, maybe need pilots VISA if you make serial or something of this nature, you may need the channels or tasks created in the measures OR and automation if you created the it.

  There may be other things you'll need depending on what you include in your code and what tool kits that you have installed.

• Is it a up date of the device driver to Windows 8 for the second of Audiotrak Midi

  Have successfully used Midi Mate with my digital piano and Sibelius 5.2, but has new laptop Windows 8 and although it recognizes the device it shows a problem and will not work. have you tried the troubleshooting, but it cannot remedy. The problem, it was not until the date of the driver available? (Ads seem to indicate that they can be purchased)

  It says here http://www.esi-audio.com/products/midimate2/> it is supported natively in Win8 with no additional drivers. You can see the FAQ section for possible solutions.

  Have you tried different USB ports?

  What error messages are you getting? Have you looked in the Device Manager to see if he demonstrated a "!" sign next to it? Have you tried "Update drivers" in the Device Manager? Have you looked into the event logs for maybe a little more details on the error messages?
