获取 EXE 文件版本信息

以下演示如何将获取一个可执行文件的版本信息，并将其放入 ListBox：

{
Usage:
VersionInformation(ListBox1)
}

{Pads or truncates a String and
Justifies Left if StrJustify=True}
Function StringPad(
InputStr,
FillChar: String;
StrLen: Integer;
StrJustify: Boolean): String;
Var
TempFill: String;
Counter : Integer;
Begin
If Not (Length(InputStr) = StrLen) Then
Begin
If Length(InputStr) > StrLen Then
Begin
InputStr := Copy(InputStr,1,StrLen) ;
End
Else
Begin
TempFill := '';
For Counter := 1 To StrLen-Length(InputStr) Do
Begin
TempFill := TempFill + FillChar;
End;
If StrJustify Then
Begin
{Left Justified}
InputStr := InputStr + TempFill;
End
Else
Begin
{Right Justified}
InputStr := TempFill + InputStr ;
End;
End;
End;
Result := InputStr;
End;


Function VersionInformation(
ListBox : TListBox): Boolean;
const
InfoNum = 11;
InfoStr : array [1..InfoNum] of String =
('CompanyName', 'FileDescription', 'FileVersion',
'InternalName', 'LegalCopyright', 'LegalTradeMarks',
'OriginalFilename', 'ProductName', 'ProductVersion',
'Comments', 'Author') ;
LabelStr : array [1..InfoNum] of String =
('Company Name', 'Description', 'File Version',
'Internal Name', 'Copyright', 'TradeMarks',
'Original File Name', 'Product Name',
'Product Version', 'Comments', 'Author') ;
var
S : String;
n, Len, j : Integer;
Buf : PChar;
Value : PChar;
begin
Try
S := Application.ExeName;
ListBox.Items.Clear;
ListBox.Sorted := True;
ListBox.Font.Name := 'Courier New';
n := GetFileVersionInfoSize(PChar(S),n) ;
If n > 0 Then Begin
Buf := AllocMem(n) ;
ListBox.Items.Add
(StringPad('Size',' ',20,True)+' = '+IntToStr(n)) ;
GetFileVersionInfo(PChar(S),0,n,Buf) ;
For j:=1 To InfoNum Do Begin
If VerQueryValue(Buf,PChar('StringFileInfo\040904E4\'+
InfoStr[j]),Pointer(Value),Len) Then
Begin
Value := PChar(Trim(Value)) ;
If Length(Value) > 0 Then
Begin
ListBox.Items.Add
(StringPad(labelStr,' ',20,True)+' = '+Value) ;
End;
End;
End;
FreeMem(Buf,n) ;
End
Else Begin
ListBox.Items.Add
('No FileVersionInfo found') ;
End;
Result := True;
Except
Result := False;
End;
End;
