Hi everyone.
I have a guid that's in string format. I would like to convert it to a
GUID. I'm doing this on the unix platform, so it will apply to only to
GCC/G++.
#include "stdafx.h"
#include <iostream>
#include <iomanip>
#include <string>
using namespace std;
typedef struct _GUID
{
unsigned long l;
unsigned short s1;
unsigned short s2;
unsigned char c[8];
} GUID;
int main() {
GUID g;
//String is in hex format.
string s1 = ("7B41464136344 430382D35413242 2D34");
//how do i get g = s1?!
}
Also, is working with GUIDs without using MFC/ATL/.NET a viable
strategy? 3 18293

Depends on your intended usage. If you need to secure a long unique id,
then why not? If your universe is much smaller, perhaps a 32-bit id
will be sufficient, which will also be easier to calculate on.

Actually, it doesn't matter on Win32. rpc api provides Uuid*
family of functions for obtaining GUIDs and converting them
to/from string/binary form. I believe that MFC/ATL/.NET just use
this service through rpc api (look up in msdn for details).
Just one note though. Win32 used string guid/uuid representation
with dashes: xxxxxxxx-xxxx-xxxx-xxxxxxxxxxxxxxx . Isn't it
standard in unix world as well?

For linux, do 'man uuidgen', or see: http://linux.about.com/library/cmd/blcmdl1_uuidgen.htm http://linux.about.com/library/cmd/blcmdl3_libuuid.htm This thread has been closed and replies have been disabled. Please start a new discussion. Similar topics |

I have the the folllowing code that works when Option Strict is Off:
Dim SearchID as string = "2F0B92F1-23E5-4CFA-B8D6-FAFEADE90EBC"
Dim SearchGUID As Guid
SearchGUID = GetConverter(SearchGUID).ConvertFrom(SearchID)
GetConverter is used with the following Imports Object:

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
Here is my compilation command:

Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
