如何从文本框中获取价值？

我在1周前开始使用C ++，并学到了很多有用的东西。现在我正在编写一个在线游戏的黑客。我这样做了; 

DWORD ENEMY = 0x01516370; //Base address
DWORD ENEMY_OFFSET = 0x4;

void Map1Function(bool fEnable)
{
 if(fEnable)
 {
WritePointer(ENEMY, ENEMY_OFFSET, textbox1->Text);
}
else
 { 
WritePointer(ENEMY, ENEMY_OFFSET, textbox1->Text);
 }
}

如何从文本框中获取价值？感谢。

我的功能：

#include <Windows.h>
bool WritePointer(unsigned long ulBase, int iOffset, int iValue)
{
  __try { *(int*)(*(unsigned long*)ulBase + iOffset) = iValue; return true; }
  __except (EXCEPTION_EXECUTE_HANDLER) { return false; }
}

但是，当我这样做时，它会给出错误^：

c:\users\*\documents\visual studio 2010\projects\tutorial\tutorial\Hacks.h(63): error         C2065: 'textbox1' : undeclared identifier
1>c:\users\*\documents\visual studio 2010\projects\tutorial\tutorial\Hacks.h(63): error  C2227: left of '->Text' must point to class/struct/union/generic type

答案 0 :(得分：2)

它是 textBox1 ，而不是 textbox1 ;变量区分大小写。

此外，这不起作用，您需要将字符串从 Text 属性转换为int值。你需要这个：

private: System::Void button1_Click(System::Object^  sender, System::EventArgs^  e)
{
    int value = Convert::ToInt32(textBox1->Text);
    WritePointer(ENEMY, ENEMY_OFFSET, value);
}

注意textBox1如何在Form1类中使用。这是必要的，因为textBox1是该类的私有。
