用程式碼實現註冊Ocx和Dll
在windows系統中,可以通過Regsvr32來實現註冊ocx或者dl,
程式設計時,呼叫Regsvr32來註冊,卻不能正常執行。尤其是在Win7系統中,需要管理員身份才能執行。
使用下面的程式碼則能正常註冊。
//註冊
function RegisterDllServer(FileName: string): boolean;
var
nDllAddr: integer;
bstr: string;
ProcAddr: Pointer;
str: PAnsiChar;
begin
Result := False;
if not FileExists(FileName) then
exit;
nDllAddr:=LoadLibrary(PWideChar(FileName));
if nDllAddr <> 0 then
begin
bstr:='DllRegisterServer'+chr(0);
str := PAnsiChar(AnsiString(bstr));
ProcAddr := GetProcAddress(nDllAddr,str);
if ProcAddr<>nil then
begin
CallWindowProc(ProcAddr,nDllAddr,0,0,0);
Result := True;
end;
FreeLibrary(nDllAddr);
end;
end;
//反註冊
function UnRegisterDllServer(FileName: string): boolean;
var
nDllAddr: integer;
bstr: string;
ProcAddr: Pointer;
str: PAnsiChar;
begin
Result := False;
if not FileExists(FileName) then
exit;
nDllAddr:=LoadLibrary(PWideChar(FileName));
if nDllAddr <> 0 then
begin
bstr:='DllUnregisterServer'+chr(0);
str := PAnsiChar(AnsiString(bstr));
ProcAddr := GetProcAddress(nDllAddr,str);
if ProcAddr<>nil then
begin
CallWindowProc(ProcAddr,nDllAddr,0,0,0);
Result := True;
end;
FreeLibrary(nDllAddr);
end;
end;
