取得某一dll所有输出函数名 - DELPHI
在uses里加上ImageHlp

 

procedure ListDLLFunctions(DLLName: String; List: TStrings);

type

chararr = array [0..$FFFFFF] of Char;

var

H: THandle;

I,

fc: integer;

st: string;

arr: Pointer;

ImageDebugInformation: PImageDebugInformation;

begin

List.Clear;

DLLName := ExpandFileName(DLLName);

if FileExists(DLLName) then

begin

H := CreateFile(PChar(DLLName), GENERIC_READ, FILE_SHARE_READ or

FILE_SHARE_WRITE, nil, OPEN_EXISTING, FILE_ATTRIBUTE_NORMAL, 0);

if H<>INVALID_HANDLE_VALUE then

try

ImageDebugInformation := MapDebugInformation(H, PChar(DLLName), nil, 0);

if ImageDebugInformation<>nil then

try

arr := ImageDebugInformation^.ExportedNames;

fc := 0;

for I := 0 to ImageDebugInformation^.ExportedNamesSize - 1 do

if chararr(arr^)[I]=#0 then

begin

st := PChar(@chararr(arr^)[fc]);

if Length(st)>0 then

List.Add(st);

if (I>0) and (chararr(arr^)[I-1]=#0) then

Break;

fc := I 1

end

finally

UnmapDebugInformation(ImageDebugInformation)

end

finally

CloseHandle(H)

end

end

end;

 

procedure TForm1.Button1Click(Sender: TObject);

var

List: TStrings;

I: integer;

S: String;

 

begin

List := TStringList.Create;

 

ListDLLFunctions('c:\windows\system\Abcsda.dll', List);

showmessage(inttostr(list.count));

S := 'List of functions';

for I := 0 to List.Count - 1 do

S := S #13#10 List[I];

ShowMessage(S);

 

List.Free

end;
