What the....GUIDS????

Recommended Posts

Hey, i know what GUID''s are but the book I bought didn''t come with it(the software called GUID). Does anyone know where I can get it? Or is there a better way to making id''s for your com objects? Thanks for your time.

DirectX objects inherit the IUNKNOWN interface, and as long as you link dxguid.lib, that should do it for you!

You also should #define INITGUID in one of your apps, and call CoInitialize(NULL); at the top of your WINMAIN file, and CoUninitialize(); after the shutdown of your app.

guidgen doesn''t come with Windows; however, it does come with the Platform SDK (and ships with MSVC).

But, you don''t need guidgen to create a new GUID. Create a program and call the CoCreateGuid() function in objbase.h or the UuidCreate() function in Rpcdce.h to create a new GUID and then use UuidToString() to output the GUID that you can then use in your programs.


  
#include <windows.h>
#include <rpcdce.h>
#include <iostream>

int main(void) {
UUID id;
unsigned char * id_string;

UuidCreate(&id);
UuidToString(&id, &id_string);

std::cout << id_string << std::endl;

RpcStringFree(&id_string);

return 0;
}

Requires rpcrt4.lib, so with MinGW you''d compile it with
g++ -o guid.exe guid.cpp -lrpcrt4
