方法一，取回来的都是字符串：
procedure TForm1.ShowVersion;
const
InfoNum = 9;
InfoStr: array[1..InfoNum] of string = (
'ProductName',
'ProductVersion',
'FileDescription',
'LegalCopyright',
'FileVersion',
'CompanyName',
'LegalTradeMarks',
'InternalName',
'OriginalFileName'
);
var
S: string;
BufSize, Len: DWORD;
Buf: PChar;
Value: PChar;
begin
mmo1.Clear;
S := FFileName;
BufSize := GetFileVersionInfoSize(PChar(S), BufSize);
if BufSize > 0 then
begin
Buf := AllocMem(BufSize);
GetFileVersionInfo(PChar(S), 0, BufSize, Buf);
if VerQueryValue(Buf, PChar('StringFileInfo\080403A8\' + InfoStr[1]), Pointer(Value), Len) then
mmo1.Lines.Add('产品名称：' + Value);
if VerQueryValue(Buf, PChar('StringFileInfo\080403A8\' + InfoStr[2]), Pointer(Value), Len) then
mmo1.Lines.Add('产品版本: ' + Value);
if VerQueryValue(Buf, PChar('StringFileInfo\080403A8\' + InfoStr[3]), Pointer(Value), Len) then
mmo1.Lines.Add('文件说明: ' + Value);
if VerQueryValue(Buf, PChar('StringFileInfo\080403A8\' + InfoStr[4]), Pointer(Value), Len) then
mmo1.Lines.Add('合法版权: ' + Value);
if VerQueryValue(Buf, PChar('StringFileInfo\080403A8\' + InfoStr[5]), Pointer(Value), Len) then
mmo1.Lines.Add('文件版本: ' + Value);
if VerQueryValue(Buf, PChar('StringFileInfo\080403A8\' + InfoStr[6]), Pointer(Value), Len) then
mmo1.Lines.Add('公司名称: ' + Value);
if VerQueryValue(Buf, PChar('StringFileInfo\080403A8\' + InfoStr[7]), Pointer(Value), Len) then
mmo1.Lines.Add('合法商标: ' + Value);
if VerQueryValue(Buf, PChar('StringFileInfo\080403A8\' + InfoStr[8]), Pointer(Value), Len) then
mmo1.Lines.Add('内部名称: ' + Value);
if VerQueryValue(Buf, PChar('StringFileInfo\080403A8\' + InfoStr[9]), Pointer(Value), Len) then
mmo1.Lines.Add('原文件名: ' + Value);
FreeMem(Buf, BufSize);
end
else
begin
Application.MessageBox('获取产品信息时遇到致命错误，请尝试重新启动软件。'+ #13 + '若仍未能解决问题，请联系产品服务人员。','错误',MB_OK + MB_ICONSTOP);
end;
end;
方法二，取得都是值：
Type
TVersion = record
Major: Word;
Minor: Word;
Release: Word;
Build: Word;
end;
procedure TForm1.btn1Click(Sender: TObject);
var
foo, VersionSize: dword;
Versionbuf: pointer;
vs: PVSFixedFileInfo;
FileVer: TVersion;
begin
if dlgOpen1.Execute then
begin
FFileName := dlgOpen1.FileName;
end;
VersionSize := GetFileVersionInfoSize(pchar(FFileName), foo);
if VersionSize > 0 then
begin
GetMem(VersionBuf, VersionSize);
if GetFileVersionInfo(pchar(FFileName), 0, VersionSize, VersionBuf) then
begin
VerQueryValue(VersionBuf, '\', Pointer(vs), VersionSize);
with FileVer do
begin
Major := vs.dwFileVersionMS div $10000;
Minor := vs.dwFileVersionMS mod $10000;
Release := vs.dwFileVersionLS div $10000;
Build := vs.dwFileVersionLS mod $10000;
end;
end;
Freemem(VersionBuf);
end;
mmo1.Clear;
mmo1.Lines.Add('Major:' + IntToStr(FileVer.Major));
mmo1.Lines.Add('Minor:' + IntToStr(FileVer.Minor));
mmo1.Lines.Add('Release:' + IntToStr(FileVer.Release));
mmo1.Lines.Add('Build:' + IntToStr(FileVer.Build));
end;
方法三（基本与一类似）：
type
TEXEVersionData = record
CompanyName,
FileDescription,
FileVersion,
InternalName,
LegalCopyright,
LegalTrademarks,
OriginalFileName,
ProductName,
ProductVersion,
Comments,
PrivateBuild,
SpecialBuild: string;
end;
function GetEXEVersionData(const FileName: string): TEXEVersionData;
type
PLandCodepage = ^TLandCodepage;
TLandCodepage = record
wLanguage,
wCodePage: word;
end;
var
dummy,
len: cardinal;
buf, pntr: pointer;
lang: string;
begin
len := GetFileVersionInfoSize(PChar(FileName), dummy);
if len = 0 then
RaiseLastOSError;
GetMem(buf, len);
try
if not GetFileVersionInfo(PChar(FileName), 0, len, buf) then
RaiseLastOSError;
if not VerQueryValue(buf, '\VarFileInfo\Translation\', pntr, len) then
RaiseLastOSError;
lang := Format('%.4x%.4x', [PLandCodepage(pntr)^.wLanguage, PLandCodepage(pntr)^.wCodePage]);
if VerQueryValue(buf, PChar('\StringFileInfo\' + lang + '\CompanyName'), pntr, len){ and (@len <> nil)} then
result.CompanyName := PChar(pntr);
if VerQueryValue(buf, PChar('\StringFileInfo\' + lang + '\FileDescription'), pntr, len){ and (@len <> nil)} then
result.FileDescription := PChar(pntr);
if VerQueryValue(buf, PChar('\StringFileInfo\' + lang + '\FileVersion'), pntr, len){ and (@len <> nil)} then
result.FileVersion := PChar(pntr);
if VerQueryValue(buf, PChar('\StringFileInfo\' + lang + '\InternalName'), pntr, len){ and (@len <> nil)} then
result.InternalName := PChar(pntr);
if VerQueryValue(buf, PChar('\StringFileInfo\' + lang + '\LegalCopyright'), pntr, len){ and (@len <> nil)} then
result.LegalCopyright := PChar(pntr);
if VerQueryValue(buf, PChar('\StringFileInfo\' + lang + '\LegalTrademarks'), pntr, len){ and (@len <> nil)} then
result.LegalTrademarks := PChar(pntr);
if VerQueryValue(buf, PChar('\StringFileInfo\' + lang + '\OriginalFileName'), pntr, len){ and (@len <> nil)} then
result.OriginalFileName := PChar(pntr);
if VerQueryValue(buf, PChar('\StringFileInfo\' + lang + '\ProductName'), pntr, len){ and (@len <> nil)} then
result.ProductName := PChar(pntr);
if VerQueryValue(buf, PChar('\StringFileInfo\' + lang + '\ProductVersion'), pntr, len){ and (@len <> nil)} then
result.ProductVersion := PChar(pntr);
if VerQueryValue(buf, PChar('\StringFileInfo\' + lang + '\Comments'), pntr, len){ and (@len <> nil)} then
result.Comments := PChar(pntr);
if VerQueryValue(buf, PChar('\StringFileInfo\' + lang + '\PrivateBuild'), pntr, len){ and (@len <> nil)} then
result.PrivateBuild := PChar(pntr);
if VerQueryValue(buf, PChar('\StringFileInfo\' + lang + '\SpecialBuild'), pntr, len){ and (@len <> nil)} then
result.SpecialBuild := PChar(pntr);
finally
FreeMem(buf);
end;
end;
