Hi,

I want to write text to a file in SDCard. The code I had written is below:

public EditField editfield;

public String filepath="file:///SDCard/BlackBerry/documents/Test.txt";

try

{

FileConnection fconn=(FileConnection)Connector.open(filepath,Connector.READ_WRITE);

if(!fconn.exists())

{

fconn.create();

}

OutputStream os=fconn.openOutputStream();

os.write(editfield.getText().getBytes());

os.close();

fconn.close();

catch(IOException ioe)

{

}

When I debug the code the file got created;but when i entered some  text data in simulator the data is not written in the file.

Can anyone help me on this.

If possible i want sample code to read  data from the same file.

Did you setup the simulator to emulate an SD card?

When ur code will run at that time ur EditField is Blank. So no data are in the file.

Postur full code.

Yes.

In the Memory of simulator i had specified the path.

Hi!!

Thanks for Reply.

i'm providing the entire code here.

public FileAppMainScreen() 

{

// TODO Auto-generated constructor stub

editfield=new EditField("Enter Text:","");

add(editfield);

try

{

FileConnection fconn=(FileConnection)Connector.open(filepath,Connector.READ_WRITE);

if(!fconn.exists())

{

fconn.create();

}

OutputStream os=fconn.openOutputStream();

os.write(editfield.getText().getBytes());

os.write("testcontentWelcome".getBytes());

//os.close();

}

catch(IOException ioe)

{

}

}

first the data put in the byte array. then try to write that byte array in the file.

I created array of type byte; assigned array to get data from edit field and tried to write the array contents to the file.

No debugging errors but data is not writing to the file.

Thank U

This works for me:

  public String write(String[] textArr,int lengthArr)
  {
    if(checkCard()<2) return("NOK No SDCARD");
         
    String fileUrl = "file:///SDCard/LogFile.txt";
    try
    {
      FileConnection fconn = (FileConnection)Connector.open( fileUrl);
// If no exception is thrown, then the URI is valid, but the file may or may not exist.
      if (!fconn.exists())
         fconn.create();                      // create the file if it doesn't exist
      else
      {
     fconn.delete();                      //Create a new one
     fconn.create();
      }
      OutputStream os =fconn.openOutputStream();
      String record;
      for(int i=0;i<lengthArr;i++)
       {  
     if(textArr[i].endsWith("\n")==false) 
           record = textArr[i]+"\n";
     else
        record = textArr[i]; 
        os.write(record.getBytes());
       } 
      os.close();
      os = null;
      fconn.close();
      fconn = null;
      return "OK";
    }
    catch (IOException ioe)
    {
     return("NOK " + ioe.getMessage());   
    }     
  } 
  private int checkCard()
  { 
   int returnvalue=0; 
   String root = null;
   Enumeration e = FileSystemRegistry.listRoots();
   while (e.hasMoreElements())
    {
     root = (String) e.nextElement();
     if( root.equalsIgnoreCase("sdcard/") )
      {
       returnvalue = returnvalue + 2;
      }  
     else if( root.equalsIgnoreCase("store/") )
      {
       returnvalue = returnvalue + 1;
      }
     } 
    return returnvalue; 
  }
}

The data entered in the Edit field is succsessfully written in to the Text File.
