I have almost finished a "find and replace" program and I want the capability to be abe to drag the text file to be modified directly into the program. How could I signal to my program: "this file is trying to acess you, read it's contents and recognize it's file path"?
Code:#include <cmath> #include <complex> bool euler_flip(bool value) { return std::pow ( std::complex<float>(std::exp(1.0)), std::complex<float>(0, 1) * std::complex<float>(std::atan(1.0) *(1 << (value + 2))) ).real() < 0; }
Here's a hint. It has to do with argc and argv
Try declaring main like so:
int main(int argc, char **argv)
If argv[1] is not null, use argv[1] as the file naame to read.
The box said 'Windows NT or better', so I installed Linux.
It works I would guess because of the command shell.
argv[0] is the executable filename: program.exe
argv[1] is the name of the text file.
Try using argv[1] to open the file 'if condition' it exists.
Infact you should perform several tests to make sure that the file is a valid textfile.
Play around with it and run some tests.

I compile code with:
Visual Studio.NET beta2
Aaargv!
It was right under my nose!
Thanks Guys!
