NewGuidStringNoBraces

Function NewGuidStringNoBraces: string

Example​

procedure ScriptEvent(var Value: variant);
begin
  Value := NewGuidStringNoBraces;
  // Shape: XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX
end;

Usage​

NewGuidStringNoBraces requests a new Windows UUID and returns uppercase 36-character hyphenated text.

Returns

XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX, with uppercase hex and four hyphens.

Important usage notes

  • No braces are returned, but hyphens remain; this is not a compact 32-character encoding.
  • Casing is uppercase under Velox.
  • UUID-generation status is lost before formatting, exactly as for NewGuid and NewGuidString.
  • The output is not validated as nonzero and is not checked against stored identifiers.
  • Treat it as an identifier, not a secret, token or creation-time-ordered key.

Additional Technical Info​

NewGuidStringNoBraces requests a Windows UUID, formats it through Delphi's standard brace-wrapped representation, then removes the two generated braces. The final form is 36 uppercase hexadecimal/hyphen characters.

The example shows only the nondeterministic result shape. It is source-reviewed and was not executed by the documentation workflow.

Implementation

The exact chain is:

NewGuidStringNoBraces
  -> NewGuidString
  -> GUIDToString(NewGuid)
  -> CreateGUID / Windows UuidCreate (status ignored)
  -> NoBraces(generated 38-character string)

NoBraces has unsafe behavior on arbitrary unbalanced strings, but this call path supplies a guaranteed {...} result from Delphi GUIDToString, so its first/last-character removal is well-defined.

Side effects and errors

One Windows UUID request and short string allocations. No persistent write. Generation status is ignored; DLL/runtime/allocation failures may still propagate.

Performance and concurrency

Constant-size OS generation and formatting work with no Velox shared counter.
