[toxcct][VisualCalc 2.20][VCalc 3.0 soon...].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, Premalatha

[toxcct][VisualCalc 2.20][VCalc 3.0 soon...]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); //get the number of characters infile.read(buffer,size); ofstream outfile; outfile.open("new_file.txt"); outfile.write(buffer,size);The syntax might be wrong Kelvin Chikomo -

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".

this file don't seem to be binary (as we can see plainly with notepad for e.g.)

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.

Thanks for ur code i'll try and let u know
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.

Thanks for ur code i'll try and let u know
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! rateep "faith, hope, love remain, these three.....; but the greatest of these is love" -1 Corinthians 13:13
