Two articles from Microsoft:
Automating Excel from C++ with MFC or without.

Yes. Just move it into the loop


for(i=0; i<=2; i++)
{
printf("Please enter the the text you want to see in the .txt file: ");
fflush(stdin);
gets(string1[i]);
fputs(string1[i],pfile); ...

I don't see why you need the temp arrays. You could simply write:



if( found == 0 )
{
delete[] stockNames[c];
delete[] stockFullName[c];
delete[] stockPrice[c];

If you can't find a direct way of doing this you can try the same approach used by unlocker i.e finding which processes have locked the drive and unlocking/killing them.
Or if you're into reverse...
