`pdfGetTextFieldValue`

Read a text field's current (/V) and default (/DV)

BOOL32 __stdcall pdfGetTextFieldValue(PPDF IPDF, uint32_t AField, const char* Value, BOOL32* ValIsUnicode, const char* DefValue, BOOL32* DefValIsUnicode);

Delphi

function pdfGetTextFieldValue(const IPDF: PPDF; AField: Cardinal; var Value: PAnsiChar; var ValIsUnicode: LongBool; var DefValue: PAnsiChar; var DefValIsUnicode: LongBool): LongBool; stdcall;

Purpose. Read a text field's current (/V) and default (/DV) values.

Description. **Value/DefValue are output-only var PAnsiChar despite their misleading const char* C declarations (the established disguised-output pattern). Both ValIsUnicode and DefValIsUnicode are always forced False** — QueryTextFieldValue only exposes a narrow (ANSI) form regardless of the field's actual stored encoding, the same one-sided-Unicode limitation already confirmed for pdfGetJavaScript (JavaScript, FDF Import, Usage Rights, and Custom Data) and pdfGetFieldMapName (Field Naming, Identity, and Flags).

Parameters.

Parameter	Description
`IPDF`	Document handle.
`AField`	Target field handle.
`Value`, `DefValue`	Output only.
`ValIsUnicode`, `DefValIsUnicode`	Output: always `False`.

Return value. True if AField resolves; False otherwise.
