Only spent a few minutes looking at this. I don't remember any of these APIs anyways.

Maybe this has something to do with it:

std::string Memory::ReadStr(DWORD dwBase, INT iOffset) {
	ULONG_PTR* ulBase = (ULONG_PTR *)dwBase;

			return *(std::string*)((*(int*)ulBase) + iOffset);
	return 0;
};


You can't reinterpret a C-string as a std::string and expect it to be valid. Instead, construct a new one:
1
2
 
char const* cstring = reinterpret_cast<char const*>(*(int*)ulBase) + iOffset);
return std::string(cstring);

i still get the same error with that code
'ToString': is not a member of 'std::basic_string<char,std::char_traits<char>,std::allocator<char>>'
 
 
textBox1->Text = lib->getName().ToString();
Ganado (6784)
std::basic_string<char,std::char_traits<char>,std::allocator<char>>
is just how the bad-UI compiler internally sees std::string.

So, that particular error is pretty clear: std::string does not have a method called ToString.

Are you using Microsoft's "C++\CLI"? .NET's Object::ToString() is a different beast than the standard library's std::strings. But you don't appear to be using C++\CLI, rather just the Win32 API, so I don't think you'll have access to .NET objects or methods.

I do not see your definition of "textBox1", or your definition of "lib". What are those? What types are they? What are they defined as?

sorry for late reply and yes im using c++/cli
 
 
Library *lib = new Library(false);

this defines lib
Carat1 (50)
ideas anyone?
Ganado (6784)
If you want to use the ToString() method, don't use std::strings. Use System::String^. Or, you can still use std::strings, but then convert each string to a System::String^ before calling ToString()

Here's an SO post about converting std::strings and C++/CLI strings https://stackoverflow.com/questions/946813/c-cli-converting-from-systemstring-to-stdstring

std::string model(lib->getIGN());
				String^ MyString = gcnew String(lib->getIGN().c_str());
				richTextBox1->Text = MyString;

thanks!!!!!!!!!! thanks a lot! i just converted std::string to System::String^
