Does Delphi have anything built-in to generate UUIDs?

program Guid;

{$APPTYPE CONSOLE}

uses
SysUtils;

var

Uid: TGuid;
Result: HResult;

begin
Result := CreateGuid(Uid);
if Result = S_OK then
   WriteLn(GuidToString(Uid));
end.

Under the covers CreateGuid() calls one of the various APIs, depending on the platform. For example on Windows, it nowadays calls UuidCreate.

SysUtils.CreateGUID Function, CreateGUID sets Guid to a new-created Globally Unique Identifier. Note: Under Windows //This example demonstrates the usage of some GUID related routines along with //the type itself. // void __fastcall Delphi Examples: Copy Code. (Delphi ActiveX) Generate UUID Demonstrates how to generate a random UUID string (also known as GUID) having the standard UUID format such as "de305d54-75b4-431b-adb2-eb6b9e546014".

Also, if you need a GUID for an interface declaration, hit ctrl+shift+g in the code editor to insert a GUID at the caret.

If you're using one of the latest version of Delphi, and include SysUtils, you can call TGuid.NewGuid to generate a new guid.

NewGuid is actually implemented in a helper class for TGuid (TGuidHelper), which is declared in SysUtils.

This function calls the CreateGUID method (also in SysUtils and already mentioned in the answer by Mitch Wheat), which is actually a cross platform function that calls different libraries depending on the platform it runs on.

How to create GUID at runtime, To create a GUID (Globally Unique Identifier) at runtime I have two different ways of doing this. First Method Add ComObj unit to the uses clause� A simple GUID generator function for Delphi Here is a little code sample, that I run into the other day. The actual URL is here , but since the original site is now closed, I thought that I could save this posting on my blog as well.

Yes TGUID, see this example

program Guid;

{$APPTYPE CONSOLE}

uses
SysUtils;

begin
  WriteLn(TGUID.NewGuid.ToString());
end.

Gerenating a GUID using Delphi 7 |, In Delphi, GUID values are represented with the TGuid record defined in the System For example, '123ABC45-65DE-F0F0-4242-A1B2C3D4E5F699' is a valid� To create a GUID (Globally Unique Identifier) at runtime I have two different ways of doing this. First Method Add ComObj unit to the uses clause, if not already there, then to create the GUID as a string just do the following:

Delphi DLL Generate UUID, (Delphi DLL) Generate UUID. Demonstrates how to generate a random UUID string (also known as GUID) having the standard UUID format such as� { This example demonstrates the usage of some GUID related routines along with the type itself. } procedure TForm2.FormCreate(Sender: TObject); var MyGuid0, MyGuid1 : TGUID; begin { Create a new GUID from the string representation } MyGuid0 := StringToGUID('{00020400-0000-0000-C000-000000000046}'); Memo1.Lines.Add('The GUID is: ' + GUIDToString(MyGuid0)); { Accessing GUID's internal fields.

uuid generator in python Code Example, Get code examples like "uuid generator in python" instantly right from your google search Delphi queries related to “uuid generator in python”. I have a very simple piece of test code to generate and display a GUID on the screen every time a user clicks on a button on a form. When I compile the program and run the executable on my Windows 2000 machine, I get a unique GUID every time I click the button, which is what I expect from the documentation.

Delphi UUID generator?, Delphi UUID generator? Also, if you need a GUID for an interface declaration, hit ctrl+shift+g in the code editor to insert a GUID at the caret. Note. where each x is a hexadecimal digit (0 through 9 or A through F). On Windows, the Type Library editor automatically generates GUIDs for new interfaces. You can also generate GUIDs by pressing Ctrl+Shift+G in the Code editor. TGUID provides a structured access to this GUID : D1 maps to the first 8 hexadecimal digits.

Comments
  • That is a fast way to do, helped me a lot.
  • is this cross platform?
  • @MehmetFide - you can check yourself the documentation docwiki.embarcadero.com/Libraries/Tokyo/en/…
  • This was what I was looking for, but it didn't fully work. Since it is a class helper for TGUID, actually calling TGuidHelper.NewGuid doesn't work. You need to call TGuid.NewGuid. And that only works if you explicitly include SysUtils, because TGuid is system, but the helper is in SysUtils. I hope you don't mind that I updated the answer with this information.
