如何获取文件的版本信息？

[redlegend_126_com]

用一下这几个函数,就可以搞定了!
Getfileversioninfosize()
getfileversioninfo()
verqueryvalue()

[dregs2002]

使用TVerInfoRes类；封装了三个函数：1.GetFileVersionInfoSize;
2.GetFileVersionInfo;
3.VerQueryValue;

[torble]

type
TFileInfo = packed record
CommpanyName: string;
FileDescription: string;
FileVersion: string;
InternalName: string;
LegalCopyright: string;
LegalTrademarks: string;
OriginalFileName: string;
ProductName: string;
ProductVersion: string;
Comments: string;
VsFixedFileInfo:VS_FIXEDFILEINFO;
UserDefineValue:string;
end;

///UserDefine就是用户自定义的了，返回值保存在Info.UserDefineValue中

function GetFileVersionInfomation(const FileName: string; var info: TFileInfo;UserDefine:string=''):
boolean;
const
SFInfo= '\StringFileInfo\';
var
VersionInfo: Pointer;
InfoSize: DWORD;
InfoPointer: Pointer;
Translation: Pointer;
VersionValue: string;
unused: DWORD;
begin
unused := 0;
Result := False;
InfoSize := GetFileVersionInfoSize(pchar(FileName), unused);
if InfoSize > 0 then
begin
GetMem(VersionInfo, InfoSize);
Result := GetFileVersionInfo(pchar(FileName), 0, InfoSize, VersionInfo);
if Result then
begin
VerQueryValue(VersionInfo, '\VarFileInfo\Translation', Translation, InfoSize);
VersionValue := SFInfo + IntToHex(LoWord(Longint(Translation^)), 4) +
IntToHex(HiWord(Longint(Translation^)), 4) + '\';
VerQueryValue(VersionInfo, pchar(VersionValue + 'CompanyName'), InfoPointer, InfoSize);
info.CommpanyName := string(pchar(InfoPointer));
VerQueryValue(VersionInfo, pchar(VersionValue + 'FileDescription'), InfoPointer, InfoSize);
info.FileDescription := string(pchar(InfoPointer));
VerQueryValue(VersionInfo, pchar(VersionValue + 'FileVersion'), InfoPointer, InfoSize);
info.FileVersion := string(pchar(InfoPointer));
VerQueryValue(VersionInfo, pchar(VersionValue + 'InternalName'), InfoPointer, InfoSize);
info.InternalName := string(pchar(InfoPointer));
VerQueryValue(VersionInfo, pchar(VersionValue + 'LegalCopyright'), InfoPointer, InfoSize);
info.LegalCopyright := string(pchar(InfoPointer));
VerQueryValue(VersionInfo, pchar(VersionValue + 'LegalTrademarks'), InfoPointer, InfoSize);
info.LegalTrademarks := string(pchar(InfoPointer));
VerQueryValue(VersionInfo, pchar(VersionValue + 'OriginalFileName'), InfoPointer, InfoSize);
info.OriginalFileName := string(pchar(InfoPointer));
VerQueryValue(VersionInfo, pchar(VersionValue + 'ProductName'), InfoPointer, InfoSize);
info.ProductName := string(pchar(InfoPointer));
VerQueryValue(VersionInfo, pchar(VersionValue + 'ProductVersion'), InfoPointer, InfoSize);
info.ProductVersion := string(pchar(InfoPointer));
VerQueryValue(VersionInfo, pchar(VersionValue + 'Comments'), InfoPointer, InfoSize);
info.Comments := string(pchar(InfoPointer));
if VerQueryValue(VersionInfo, '\', InfoPointer, InfoSize) then
info.VsFixedFileInfo := TVSFixedFileInfo(InfoPointer^);
if UserDefine<>'' then
begin
if VerQueryValue(VersionInfo,pchar(VersionValue+UserDefine),InfoPointer,InfoSize) then
info.UserDefineValue:=string(pchar(InfoPointer));
end;
end;
FreeMem(VersionInfo);
end;
end;

procedure TForm1.Button1Click(Sender: TObject);
var
info: TFileInfo;
begin
if OpenDialog1.Execute then
begin
if GetFileVersionInfomation(opendialog1.FileName, info,'WOW Version') then
////我必须知道'WOW Version'才能知道有这么一个自定义的串。如果用户定义的是'abc'我就没有办法取得了。
////而资源管理器的版本信息中就不一定需要知道。它可以找出所有的版本信息。
begin
Listbox1.Items.Add(OpenDialog1.FileName);
ListBox1.Items.Add('Comments:' + info.Comments);
ListBox1.Items.Add('CommpanyName:' + info.CommpanyName);
ListBox1.Items.Add('FileDescription:' + info.FileDescription);
ListBox1.Items.Add('FileVersion:' + info.FileVersion);
ListBox1.Items.Add('InternalName:' + info.InternalName);
ListBox1.Items.Add('LegalCopyright:' + info.LegalCopyright);
ListBox1.Items.Add('LegalTrademarks:' + info.LegalTrademarks);
ListBox1.Items.Add('OriginalFileName:' + info.OriginalFileName);
ListBox1.Items.Add('ProductName:' + info.ProductName);
ListBox1.Items.Add('ProductVersion:' + info.ProductVersion);
ListBox1.Items.Add('UserDefineValue:' + info.UserDefineValue);
if boolean(info.VsFixedFileInfo.dwFileFlags and vs_FF_Debug) then
listbox1.Items.Add('Debug:True')
else
ListBox1.Items.Add('Debug:False');
ListBox1.Items.Add('');
end;
end;
end;

实际上就是实现资源管理其的文件属性--〉版本 中的功能。
实际上就是枚举文件的所有的用户自定义的版本信息字符串。
