I have a char array
when i incremnt the pointer to the array
it increments 4 bytes not 1 byte.
Is it that a console application takes anytype of padding for char array .

Since groupboxes are also buttons, I guess you have to owner draw(not me Poke tongue | ;-P

MSDN about group box: The control is created as a BUTTON class with the BS_GROUPBOX, WS_CHILD, and WS_GROUP styles.

.LRN file is a binary file which contains some float values of different parameters.

Eg:
max_ceiling : 47000
plan_area : 516
mach_cr : 0.63

Otherwise just tell me how to convert a binary file into a text file

Thanks & Regards,

For me, this looks not like a binary file. It is simple text format, the only thing is that it doesn't have a txt extension. If that bother you, you can still change the extension manually but I don't think this is a good idea. If you want to open it, you just have to right click on it and choose "open with".

Actually this is the text file format of that LRN file.

Geez, why don't you explain clearly your problem when asking your question ?

And, why do you want to change this file into text file ?
The only way to do it is to know EXACTLY what is stored in the file, in which order, ... So you'll have to do EXACTLY the same operation as done for creating the file but in the other way (so extract the data). Then when you have extracted all the data, you can print them in another file (with fprintf for example, or using the streams from the STL).

But I think you don't know what is the exact file format, am I right ? So, you can't do what you are trying to do. Or, you'll have to search on internet for the descritption of the file format and then load it yourself.

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
