Hi Pradeep,

first of all FindFirstFile and FindNextFile are not C++ functions. They are probably something your implementation provides, but since you're not giving enough context, it's unlikely you'll get a precise answer. So, the best (most generic) answer is that you use boost (http://www.boost.org) to do what you need:

1) "boost filesystem" offers portable file system operations. The official tutorial (http://www.boost.org/doc/libs/1_55_0/libs/filesystem/doc/tutorial.html) shows a directory iteration example as listing tut3.cpp.

2) Once you have a filename, CSV files are just text files, with values separated by commas. Reading a text file line by line is explained in any C++ primer, e.g. http://www.cplusplus.com/doc/tutorial/files.

3) Splitting each line at the comma can be done in many ways. The latest C++ standard offers support for regular expressions. If your compiler doesn't support it, boost also includes a portable regular expression library. If your input is really just plain comma-separated files, something like this should do: http://stackoverflow.com/questions/10058606/c-splitting-a-string-by-a-character .

Your question was really more about googling that about programming.

Cheers,

Filippo

FindFirst() and FindNext() are Windows/OS2 API calls. They are some what

analogous to doing the standard loop of opendir(); while(readdir()); closedir(); under

Unix and the C language. All they do is return the filename.

Once you have the filename, then you will need to issue an fopen(filename,"r") do

your processing, and then fclose().

Firstly, set current directory to the required. use system programming to ls >file.txt

open file.txt

for(file.txt.open ; string != EOF;readline to string)

{

system ("gedit" +" " + stringname);

}
