I am wondering how I can use a DOS-based pic. converter from a self-made program.
I have not made the program I am going to use it in, but I am probably  going to use VC++. One of the things my program is going to do is to take a picture in Targa format and convert it to another format. There are only one program that can convert to the format I need and it is a DOS-program.
The syntax for using it is: converter.exe pic.tga pic.fff

So my question is:
Can this be done?
And if it can:
How?

It is easier to use the system command.

system("converter.exe pic.tga pic.fff");

Using system(), you will see the black command window. Using CreateProcess(), you are able to hide it.
