同一个文件内的东西都用不成？
void __fastcall TForm1::FormCreate(TObject *Sender)
{
HANDLE hProcess = OpenProcess(PROCESS_ALL_ACCESS, 0, pid);
}

void __fastcall TForm1::Timer1Timer(TObject *Sender)
{
ReadProcessMemory (hProcess, (LPVOID)0xADBC80, &h, 4, NULL );
}
=========================================================

结果提示[C++ Error] Unit1.cpp(51): E2451 Undefined symbol 'hProcess '
这是怎么回事啊？

[解决办法]
TForm1的头文件中

private:
HANDLE hProcess;

——————————————————————————————————
cpp中改：
void __fastcall TForm1::FormCreate(TObject *Sender)
{
hProcess = OpenProcess(PROCESS_ALL_ACCESS, 0, pid);
}
