[Windows] VC++ obtains the process running path through PID

To obtain the process running path through the process PID in VC++, you can use the OpenProcess, GetModuleFileNameEx and CloseHandle functions in the Win32 API.

#include <Windows.h>
#include <iostream>
#include <psapi.h>
#pragma comment(lib, "psapi.lib")

int main() {
    // 获取进程句柄
    DWORD pid = 1234; // 替换为您实际的进程PID
    HANDLE handle = OpenProcess(PROCESS_QUERY_INFORMATION | PROCESS_VM_READ, FALSE, pid);
    if (handle == NULL) {
        std::cout << "无法打开进程" << std::endl;
        return 1;
    }

    // 获取进程运行路径
    char path[MAX_PATH];
    DWORD size = GetModuleFileNameEx(handle, NULL, path, MAX_PATH);
    if (size == 0) {
        std::cout << "无法获取进程运行路径" << std::endl;
        CloseHandle(handle);
        return 1;
    }
    std::cout << "进程运行路径：" << path << std::endl;

    // 关闭进程句柄
    CloseHandle(handle);

    return 0;
}

In this example, we first open the process handle using the OpenProcess function. Then, we use the GetModuleFileNameEx function to get the process running path and store it in a buffer.
Finally, output the running path of the process and close the process handle. Note that pid needs to be replaced with your actual process PID.
