检测可执行文件类型

可以使用API函数：SHGetFileInfo，参数：SHGFI_EXETYPE ************************************
Here is a function from Peter Below:
type
TExeType = (etUnknown, etDOS, etWinNE {16-bit}, etWinPE {32-bit});
function GetExeType(const FileName: string): TExeType;
{ func to return the type of executable or dll (DOS, 16-bit, 32-bit). }
(**************************************************************
Usage:
with OpenDialog1 do
if Execute then
begin
Label1.Caption := FileName;
Label2.Caption := ExeStrings[GetExetype(FileName)];
end;
- or -
case GetExeType(OpenDialog1.FileName) of
etUnknown: Label3.Caption := 'Unknown file type';
etDOS : Label3.Caption := 'DOS executable';
etWinNE : {16-bit} Label3.Caption := 'Windows 16-bit executable';
etWinPE : {32-bit} Label3.Caption := 'Windows 32-bit executable';
end;
***************************************************************)
var
Signature,
WinHdrOffset: Word;
fexe: TFileStream;
begin
Result := etUnknown;
try
fexe := TFileStream.Create(FileName, fmOpenRead or fmShareDenyNone);
try
fexe.ReadBuffer(Signature, SizeOf(Signature));
if Signature = $5A4D { 'MZ' } then
begin
Result := etDOS;
fexe.Seek($18, soFromBeginning);
fexe.ReadBuffer(WinHdrOffset, SizeOf(WinHdrOffset));
if WinHdrOffset >= $40 then
begin
fexe.Seek($3C, soFromBeginning);
fexe.ReadBuffer(WinHdrOffset, SizeOf(WinHdrOffset));
fexe.Seek(WinHdrOffset, soFrombeginning);
fexe.ReadBuffer(Signature, SizeOf(Signature));
if Signature = $454E { 'NE' } then
Result := etWinNE
else
if Signature = $4550 { 'PE' } then
Result := etWinPE;
end;
end;
finally
fexe.Free;
end;
except
end;
end;
procedure TForm1.Button1Click(Sender: TObject);
begin
if OpenDialog1.Execute then
case GetExeType(OpenDialog1.FileName) of
etUnknown: Label_ExeType.Caption := 'Unknown file type';
etDOS : Label_ExeType.Caption := 'DOS executable';
etWinNE : Label_ExeType.Caption := 'Windows 16-bit executable';
etWinPE : Label_ExeType.Caption := 'Windows 32-bit executable';
