How can i get value from textbox? - c++-cli

Question

I've started C++ 1 week ago and learnt a lot of useful things. Now i'm coding a hack for an online game. i did it like that;
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);
}
}
How can i get value from textbox ? Thanks.
My function :
#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; }
}
But it gives that error when i do it like that ^ :
c:\users\*\documents\visual studio 2010\projects\tutorial\tutorial\Hacks.h(63): error C2065: 'textbox1' : undeclared identifier

Answer 1

It's textBox1, not textbox1; variables are case sensitive.
Also, this won't work, you need to convert the string from the Text property to an int value. You will need this:
private: System::Void button1_Click(System::Object^ sender, System::EventArgs^ e)
{
int value = Convert::ToInt32(textBox1->Text);
WritePointer(ENEMY, ENEMY_OFFSET, value);
}
Notice how the textBox1 is used within the Form1 class. It is necessary because the textBox1 is private to the class.
