c++ - Getting Hex Value from Editbox and using it to read memory

Question

I'm trying to read memory, and get the values from Editbox's in my program, The caption part is working i tested it by putting a Valid address instead of MyAddress, and it worked fine. So the only problem i have is MyAddress, heres the code.

HANDLE hProcess;
DWORD ProcessId;
int Base = 0;
char MyCaption[300];
char MyAddress[300];
GetDlgItemText(hDlg, 2, MyCaption, sizeof(MyCaption));
GetDlgItemText(hDlg, 3, MyAddress, sizeof(MyAddress));
HWND hWindow = FindWindow(NULL, MyCaption);
GetWindowThreadProcessId(hWindow, &ProcessId);
hProcess = OpenProcess(PROCESS_VM_OPERATION|PROCESS_VM_READ|PROCESS_VM_WRITE, FALSE, ProcessId);
ReadProcessMemory(hProcess, (void*)MyAddress, &Base, 4, NULL);
SetDlgItemInt(hDlg, 5, Base, TRUE);

I was hopeing a function would work. Manually putting a address in works.

void write(LPVOID addy) {
    int Base = 0;
    ReadProcessMemory(hProcess, addy, &Base, 4, NULL);
    WriteProcessMemory(hProcess, (void*)(Base + 0x728), "\x88\x13\x00\x00", 4, NULL);
}

void ReadOpen(HWND hDlg)
{
    DWORD ProcessId;
    int Base = 0;
    int Base2 = 0;
    char MyCaption[300];
    GetDlgItemText(hDlg, 2, MyCaption, sizeof(MyCaption));
    HWND hWindow = FindWindow(NULL, MyCaption);
    GetWindowThreadProcessId(hWindow, &ProcessId);
    hProcess = OpenProcess(PROCESS_VM_OPERATION|PROCESS_VM_READ|PROCESS_VM_WRITE, FALSE, ProcessId);
    int address = GetDlgItemInt(hDlg, 3, NULL, FALSE);
    write((LPVOID)0x67FBF8);
}

using address doesnt work

void write(LPVOID addy) {
    int Base = 0;
    ReadProcessMemory(hProcess, addy, &Base, 4, NULL);
    WriteProcessMemory(hProcess, (void*)(Base + 0x728), "\x88\x13\x00\x00", 4, NULL);
}

void ReadOpen(HWND hDlg)
{
    DWORD ProcessId;
    int Base = 0;
    int Base2 = 0;
    char MyCaption[300];
    GetDlgItemText(hDlg, 2, MyCaption, sizeof(MyCaption));
    HWND hWindow = FindWindow(NULL, MyCaption);
    GetWindowThreadProcessId(hWindow, &ProcessId);
    hProcess = OpenProcess(PROCESS_VM_OPERATION|PROCESS_VM_READ|PROCESS_VM_WRITE, FALSE, ProcessId);
    int address = GetDlgItemInt(hDlg, 3, NULL, FALSE);
    write((LPVOID)address);
}

using &address doesnt work.

void write(LPVOID addy) {
    int Base = 0;
    ReadProcessMemory(hProcess, addy, &Base, 4, NULL);
    WriteProcessMemory(hProcess, (void*)(Base + 0x728), "\x88\x13\x00\x00", 4, NULL);
}

void ReadOpen(HWND hDlg)
{
    DWORD ProcessId;
    int Base = 0;
    int Base2 = 0;
    char MyCaption[300];
    GetDlgItemText(hDlg, 2, MyCaption, sizeof(MyCaption));
    HWND hWindow = FindWindow(NULL, MyCaption);
    GetWindowThreadProcessId(hWindow, &ProcessId);
    hProcess = OpenProcess(PROCESS_VM_OPERATION|PROCESS_VM_READ|PROCESS_VM_WRITE, FALSE, ProcessId);
    int address = GetDlgItemInt(hDlg, 3, NULL, FALSE);
    write((LPVOID)&address);
