I don`t realy understand your question, but from what i understand i suggest you open your file in binary mode and write it to a nuew file with a .txt extension.

ifstream infile;

infile.open("file_name.lnr", ios::bin);<br />
//get the number of characters <br />
<br />
infile.read(buffer,size);<br />
<br />
<br />
ofstream outfile;<br />
outfile.open("new_file.txt");<br />
outfile.write(buffer,size);

The syntax might be wrong

That won't work: this will just take everything that is in your file and paste it exactly the same in a text file. So you will be able to open your file directly with notepad but the contents will be exactly the same. There is no way of doing what you want without knowing how the data is stored in the file. That is: they saved first this variable (a float), then this string, then this integer value, ... quite difficult to know without having the sources files of the program itself.

well premlatha,the .lrn file that u have mentioned would follow a structure......
Find out the structure/class.....
then read the file thru that object.....
then open up an another file and write the the members using text formatted functions like fprintf.....

if you were to simply copy the file as it is in binary mode and then write it down in an anoter file ,all u get is a duplicate of the original file!

cheerz!

Thanks very much for your help, I were busy on my work just now and couldn't see the reply on time, i am sorry.
I tried your solution and i found it couldn't work properly.
The WM_DEVICECHANGE message is just useful while the device have actions. If the CD/DVD-ROM have disk inside, it couldn't work as what i wonder.
So I just wanna know how to judge the door, opened or closed?
Someone give me some tips that I have to SendCommand to the CD/DVD-ROM, and the return code will the me the status of it. But i don't know how to do it even i tried to see the document about "SFF Committee Information Specification for ATAPI DVD Devices" which distrubite at June 5, 2003 with the edition Rev 5.5.
