Solved Getting the contents of a memory location as a string

[Shadoninja]

I am trying to print out my player's x coordinate to the gui of my dll injected hack.

I know that xposition contains a DWORD of the address containing the player's x position, but I can't get it to assign its contents to the label xposStatus:

What is working (kinda)

xposStatus->Text = xposition.ToString();

This prints out what I wanted it to: the memory location holding my player's x coordinates. But that is only a small proof that I am on the right path.

Attempt 1: (The compiler yells at me)

xposStatus->Text = *xposition.ToString();

Attempt 2: ("Error: invalid type conversion")

xposStatus->Text = *(DWORD *)xposition.ToString();

Attempt 3: (This compiles, but doesn't change the label at all)

int test = *(DWORD *)xposition;
xposStatus->Text = test.ToString();

How can I get that float value contained in xposition?

printf("%f\n", floatVal);

So basically you have a DLL which is injected in the process. This DLL opens a window in which you want to write something. Did I understand that correclty?

Yeah, it opens up a gui created from visual studios built in win32 application support. So the object on the gui that I am trying to change is the Text element of a Label^ object from System::Windows::Forms::Label^;



This is the same structure Fleep uses in one of his tutorials, but he only uses string literals to change certain label's text to "on" or "off." I want real-time information presented, which obviously requires variable input, and the label just isn't having it.

He wants to read a float from memory and convert it to a string

 

[c5]

DWORD position = *(DWORD_PTR*)xposition;
xposStatus->Text = *(float*)position.ToString();

That line is giving me the "Invalid type conversion" error.

xposStatus->Text = *(float*)position.ToString();
      underlined red^  (the carrot is pointing to it)

And the same error happens when I do it like this

char* test = *(float*)position.ToString();
underlined red^

Honestly if there is a better way to set up the gui, I will be happy to do that. Even if its just a console window. I just want to learn a decent way of setting this all up

Order of operations is important, otherwise you'll be trying to deference a float from a string.
https://en.cppreference.com/w/cpp/language/operator_precedence
As you can see here the member access operator has a higher priority than a typecast or a dereference operator so you would need to put those in parenthese.
That said, a native float doesn't have a ToString function.

Give this a try:

xposStatus->Text = Convert::ToString(*(float*)position);
