无法在类成员函数中执行CreateProcessA函数

Question

我正在开发一个代码，它将使用win32 api函数CreateProcess执行另一个exe。

#include <iostream>
#include <windows.h>

using namespace std;

int main()
{
    STARTUPINFO startupinfo;
    PROCESS_INFORMATION process_information;
    startupinfo.dwFlags = 0x1;
    startupinfo.wShowWindow = 0x0;
    startupinfo.cb = sizeof(startupinfo);
    if (CreateProcessA ("test.exe", NULL, NULL, NULL, FALSE, 0, NULL, NULL, &startupinfo, &process_information))
    {
        cout << "[+] We have successfully launched the process\n" ;
        cout << "[+] PID: " << process_information.dwProcessId;
        WaitForSingleObject(process_information.hProcess, INFINITE);
        CloseHandle(process_information.hProcess);
        CloseHandle(process_information.hThread);
    }
    else {
         cout << "[-] Error Code: " << GetLastError();
         Sleep(3000);
    }  
    return 0; 
}

上面的代码就像一个魅力，但我想在这个项目中应用OOP概念。所以我写了......

#include <iostream>
#include <windows.h>

using namespace std;

class CppDBG
{
    public:
        void load_exe();
};

void CppDBG :: load_exe()
{
    STARTUPINFO startupinfo;
    PROCESS_INFORMATION process_information;
    startupinfo.dwFlags = 0x1;
    startupinfo.wShowWindow = 0x0;
    startupinfo.cb = sizeof(startupinfo);
    if (CreateProcessA ("test.exe", NULL, NULL, NULL, FALSE, 0, NULL, NULL, &startupinfo, &process_information))
    {
        cout << "[+] We have successfully launched the process\n" ;
        cout << "[+] PID: " << process_information.dwProcessId;
        WaitForSingleObject(process_information.hProcess, INFINITE);
        CloseHandle(process_information.hProcess);
        CloseHandle(process_information.hThread);
    }
    else {
         cout << "[-] Error Code: " << GetLastError();
         Sleep(3000);
    }   
}

int main()
{
    CppDBG dbg;
    dbg.load_exe();
    return 0;
}

上面的代码编译正确但运行不正确。

我错过了什么？
