C++如何将系统序列号传递到变量中？

我已经能够检索我的系统序列号，但如何将序列号本身传递到变量中？

    int main()
    {
        char newSerial;
        int (*ptr) (const char[]);

        ptr = system;

        ptr("wmic bios get serialnumber");      
    }

运行我的代码后，屏幕显示：

    SerialNumber
    xxxxxxxxxxxxx

完全像这样。但我想要的是将“x”传递到 char 变量中，因为它里面有一个破折号。程序到底从哪里调用序列号？有什么建议吗？（Windows 7 x64）

I've been able to retrieve my system serial number, but how do I pass the serial number itself into a variable?

    int main()
    {
        char newSerial;
        int (*ptr) (const char[]);

        ptr = system;

        ptr("wmic bios get serialnumber");      
    }

After running my code, the screen displays:

    SerialNumber
    xxxxxxxxxxxxx

exactly like this. But what I want is to pass just the "x's" into a char variable since it has a dash in it. Where exactly is the program calling the serial number from? Any suggestions? (Windows 7 x64)

通过 C++ 以编程方式访问 WMI 的官方认可方法是 WMI 的 COM API。具体请参阅 WMI 下的示例C++ 应用示例。

另一方面，如果您希望快速访问序列号，请在程序中添加以下内容：

#include <stdio.h>
#include <stdlib.h>

/*...*/

system("wmic bios get serialnumber > sn.txt");
wchar_t sn[16];

FILE* fp = fopen("sn.txt", "r, ccs=UTF-8");
fgetws(sn, 16, fp); //dummy read of first line
fgetws(sn, 16, fp); //`sn` now contains 2nd line

fclose(fp);          //cleanup temp file
remove("sn.txt");

printf("The serial Number is: %ws\n", sn);

The officially sanctioned way to get programatic access to WMI through C++ is the COM API for WMI. See specifically the examples under WMI C++ Application Examples.

If on the other hand, you want quick access to the serial number, add something along these lines to your program:

#include <stdio.h>
#include <stdlib.h>

/*...*/

system("wmic bios get serialnumber > sn.txt");
wchar_t sn[16];

FILE* fp = fopen("sn.txt", "r, ccs=UTF-8");
fgetws(sn, 16, fp); //dummy read of first line
fgetws(sn, 16, fp); //`sn` now contains 2nd line

fclose(fp);          //cleanup temp file
remove("sn.txt");

printf("The serial Number is: %ws\n", sn);

这是一种不使用文本文件的更好方法

QProcess proc;
//proc.start("cscript " + path, QIODevice::ReadWrite);
proc.start("wmic bios get serialnumber",QIODevice::ReadWrite);
//qDebug() << path;
proc.waitForFinished();
QString uID = proc.readAll();
qDebug()<<uID; // serial number of the laptop

Here is a better approach without using text file

QProcess proc;
//proc.start("cscript " + path, QIODevice::ReadWrite);
proc.start("wmic bios get serialnumber",QIODevice::ReadWrite);
//qDebug() << path;
proc.waitForFinished();
QString uID = proc.readAll();
qDebug()<<uID; // serial number of the laptop

    ShellExecute(NULL, L"open", L"cmd.exe", L"/c wmic bios get serialnumber > sn.txt", NULL, SW_HIDE);

wchar_t sn[16];
FILE* fp = fopen("sn.txt","r, ccs=UTF-8");
fgetws(sn,16,fp); //dummy read of first line
fgetws(sn,16,fp); //now sn contains 2nd line

fclose(fp);          //cleanup temp file
remove("sn.txt");  

printf("The serial Number is: %ws\n",sn);

    ShellExecute(NULL, L"open", L"cmd.exe", L"/c wmic bios get serialnumber > sn.txt", NULL, SW_HIDE);

wchar_t sn[16];
FILE* fp = fopen("sn.txt","r, ccs=UTF-8");
fgetws(sn,16,fp); //dummy read of first line
fgetws(sn,16,fp); //now sn contains 2nd line

fclose(fp);          //cleanup temp file
remove("sn.txt");  

printf("The serial Number is: %ws\n",sn);
