Hallo,
irgendwann mal im Netz gefunden:
| C++: |
//-----------------------------------------------------------------
// Klasse zum Auslesen der Versionsinformationen aus den Windows-Exe und DLLs
//-----------------------------------------------------------------
// Verwendung:
// Füllen einer Memo-Komponente mit Vesions-Informationen des
// Windows-Notepads:
VerInfo * pVer = new VerInfo("C:\\WINDOWS\\NOTEPAD.EXE");
for(int ilCount = 0; ilCount < 10; ilCount++)
{ Memo1 -> Lines -> Add(pVer -> GetVerInfo(ilCount)); }
if(pVer != NULL) { delete pVer; pVer = NULL; }
// Anstatt ilCount kann der Funktion GetVerInfo()-Funktion eine der unten
// aufgelisteten Konstanten übergeben werden
//-----------------------------------------------------------------
--- xyz.h ---
//----------------------------------------------------------------
// Konstanten für die Verwendung als Parameter mit der
// Funktion GetVerInfo(int ilId):
//-----------------------------------------------------------------
const int VI_COMPANY_NAME = 0; // Firmen-Name
const int VI_FILE_DESCRIPTION = 1; // Dateibeschreibung
const int VI_FILE_VERSION = 2; // Versionsnummer
const int VI_INTERNAL_NAME = 3; // Interner Name
const int VI_LEGAL_COPYRIGHT = 4; // Copyright-Info
const int VI_LEGAL_TRADEMARKS = 5; // Warenzeichen
const int VI_ORIGINAL_FILENAME = 6; // Orig.-Dateiname
const int VI_PRODUCT_NAME = 7; // Produktname
const int VI_PRODUCT_VERSION = 8; // Produkt-Version
const int VI_FILE_COMMENTS = 9; // Kommentare

--edit-- VCL.h noch includieren
