C++调用SetEnvironmentVariable没起作用吗？sockscap老是跳出用户名和密码的输入框，怎么永久设定？
比如SetEnvironmentVariable(SOCKS5_USER,"admin")&&SetEnvironmentVariable(SOCKS5_PASSWD,"123456")

c++

SetEnvironmentVariable
The SetEnvironmentVariable function sets the value of an environment variable for the current process.

BOOL SetEnvironmentVariable(
  LPCTSTR lpName,  // address of environment variable name
  LPCTSTR lpValue  // address of new value for variable
);

Parameters
lpName
Pointer to a null-terminated string that specifies the environment variable whose value is being set. The operating system creates the environment variable if it does not exist and lpValue is not NULL.
lpValue
Pointer to a null-terminated string containing the new value of the specified environment variable. If this parameter is NULL, the variable is deleted from the current process's environment.
Return Values
If the function succeeds, the return value is nonzero.

If the function fails, the return value is zero. To get extended error information, call GetLastError.

改为这样试试？

SetEnvironmentVariable(_T("SOCKS5_USER"),_T("admin"))&&SetEnvironmentVariable(_T("SOCKS5_PASSWD"),_T("123456"))
