Re: error : readLine is not a function

[Fabrice Esti�venart]

thanks for your answer that makes me progress...i'm trying this but that 
  makes mozilla completely crash when invoking the "readLine()" 
function(under Win2000) :

		try
		{
			var file = 
Components.classes["@mozilla.org/file/local;1"].createInstance(Components.interfaces.nsILocalFile);
			file.initWithPath("c:\\myFile.txt");

			var fileStream = 
Components.classes["@mozilla.org/network/file-input-stream;1"].createInstance(Components.interfaces.nsIFileInputStream);
			fileStream.init(file,0x01,0444,null);
			
			fileStream = 
fileStream.QueryInterface(Components.interfaces.nsILineInputStream);
			
			var line;
						
			while(fileStream.readLine(line))
			{
				alert(line);
			}
			
			fileStream.close();
		}
		catch(e)
		{
			alert(e);
		}

notice that the variable "fileStream" is not null and seems to be a 
correct implementation of both interfaces : nsIFileInputStream (needed 
to initialise the stream) AND nsILineInputStream (needed to read line by 
line)

thanks for giving me other ideas,
regards,
Fabrice

I think the problem is that you need to query it for a line input
stream... the following code should work...
inputstream.QueryInterface(Components.interfaces.nsILineInputStream);
while (inputstream.readLine(line)) {
        alert (line.value);
}
