回复: 【提问】请问QT怎么和外面的程序相连？

我没找到QProcess 这个类丫。。。。

没有找到的话那就使用C库函数吧。
#include
int system( const char *command );
The system() function runs the given command as a system call. The return value is usually zero if the command executed without errors. If command is NULL, system() will test to see if there is a command interpreter available. Non-zero will be returned if there is a command interpreter available, zero if not.

Description
Loads and runs other programs.
The functions in the exec... family load and run (execute) other programs, known as child processes. When an exec... call succeeds, the child process overlays the parent process. There must be sufficient memory available for loading and executing the child process.
path is the file name of the called child process. The exec... functions search for path using the standard search algorithm:
If no explicit extension is given, the functions search for the file as given. If the file is not found, they add .EXE and search again. If not found, they add .COM and search again. If found, the command processor, COMSPEC (Windows) or COMMAND.COM (DOS), is used to run the batch file.
If an explicit extension or a period is given, the functions search for the file exactly as given.
The suffixes l, v, p, and e added to the exec... "family name" specify that th ..

不好意思，本人菜， 再问一下
在qt的程序里#include 就可以么？
g＋＋ 时，－I 了qt的目录了， 是不是#include 就不对了？

那是标准Ｃ库文件，应该都能行的。
