  • optimizing operating systems to provide maximum informix performance.

    - by Frank Developer
    Are there any Informix-specific guides for optimizing any operating system where an ifx engine is running? For example, in Linux, strip-down to a bare minimum all unecessary binaries, daemons, utilities, tune kernel parameters, optimize raw and cooked devices (hdparm). Someday, maybe, informix can create its own proprietary PICK-like O/S. The general idea is for the OS where ifx sits on have the smallest footprint, lowest overhead impact on ifx and provide optimized ifx performance.

  • read user Input of custom dialogs

    - by urobo
    I built a custom dialog starting from an AlertDialog to obtain login information from a user. So the dialog contains two EditText fields, using the layoutinflater service I obtain the layout and I'm saving a reference to the fields. LayoutInflater inflater = (LayoutInflater) Home.this.getSystemService(LAYOUT_INFLATER_SERVICE); layoutLogin = inflater.inflate(R.layout.login,(ViewGroup) findViewById(R.id.rl)); usernameInput =((EditText)findViewById(R.id.getNewUsername)); passwordInput = ((EditText)findViewById(R.id.getNewPassword)); Then I have my overridden onCreateDialog(...) : { AlertDialog d = null; AlertDialog.Builder builder = new AlertDialog.Builder(this); switch(id){ ... case Home.DIALOG_LOGIN: builder.setView(layoutLogin); builder.setMessage("Sign in to your DyCaPo Account").setCancelable(false); d=builder.create(); d.setTitle("Login"); Message msg = new Message(); msg.setTarget(Home.this.handleLogin); Bundle data = new Bundle(); data.putString("username", usernameInput.getText().toString());// <---null pointer Exception data.putString("password", passwordInput.getText().toString()); msg.setData(data); d.setButton(Dialog.BUTTON_NEUTRAL,"Sign in",msg); break; ... return d; } and the handler set in the Message: private Handler handleLogin= new Handler(){ /* (non-Javadoc) * @see android.os.Handler#handleMessage(android.os.Message) */ @Override public void handleMessage(Message msg) { // TODO Auto-generated method stub Log.d("Message Received", msg.getData().getString("username")+ msg.getData().getString("password")); } }; which for now works as a debugging tool. That's all. The Question is: what am I doing wrong? Because when I reach the line highlighted in the code ( the line in which I read the fields in the dialog ) I always get a null pointer exception. Could somebody please tell me the reason why it is so? And give some guidelines to work with dialogs. Thanks in advance!

  • R/XLL: Interface to call XLL method in R

    - by Neerav
    I am trying to call the methods defined in the XLL addin(for Excel) from R. Something similar to this Python code: import os from win32com.client import Dispatch Path = 'myxll.xll' xlApp = Dispatch("Excel.Application") xlApp.RegisterXLL(Path) # function call from excel # =xllfunction("param1","param2",...) result = xlApp.run('xllfunction', "param1","param2",...) Is there any library in R that does the XLL interface? Thanks for your help.

  • Debugging in XCode as root

    - by Anton
    In my program I need to create sockets and bind them to listen HTTP port (80). The program works fine when I launch it from command line with sudo, escalating permissions to root. Running under XCode gives a 'permission denied' error on the call to binding function (asio::ip::tcp::acceptor::bind()). How can I do debugging under XCode? All done in C++ and boost.asio on Mac OS X 10.5 with XCode 3.1.2.

  • Go - How to read/write to file?

    - by Seth Hoenig
    I've been trying to learn Go / Golang on my own, but I've been stumped on trying read and write to ordinary files. I can get as far as: inFile,_ := os.Open(INFILE,0,0); but actually getting the content of the file doesn't make sense, since the read function takes a []byte as a parameter?? func (file *File) Read(b []byte) (n int, err Error)

  • How to simulate a USB drive

    - by rursw1
    Hi all, Is it possible to simulate a USB drive with software only? I mean, for example, to expose a local memory space to the OS so the device manager will recognize it as a USB device. I'm not familiar with hardware implementation, but I'm sure that it is possible somehow to emulate the USB protocol. I began with this book - USB Design By Example. Can anyone please give me additional references to begin with? Thank in advance!
