Viewing memory address
Author
Hi
What casting I should use to make a pointer of any type prints to a MessageBox second parameter.
For example
struct sFrame{}
sFrame *sFrame1;
MessageBox(NULL,sFrame1,""MB_OK);
Well, I want to know the memory location for sFrame1.
ManyThanks
You need to create a string with the address, not do a cast (unless you use boost::lexical_cast).

#include <sstream>struct Foo {};Foo f;int main(){ // create an output string stream std::ostringstream oss; // write the address of f to the stream oss << &f // or possibly oss << (void*)&f // extract the string from the stream, // then pass it as a const char* string to MessageBox MessageBox( NULL, oss.str().c_str(), "", MB_OK ); // clears the flags in oss (if the object is reused) oss.clear(); // clear the string in oss (if the object is reused) oss.str(""); }; Documents [ GDNet | MSDN | STL | OpenGL | Formats | RTFM | Asking Smart Questions ]

Try using sprintf() and then passing the buffer that you got from that to the MessageBox().
I know printf() can do addresses so sprintf() should be able to also.
Er.. I just noticed the one above me says how to do it also...
Well, this is just a different way. Take your pick
