在windows系统中,可以通过Regsvr32来实现注册ocx或者dl,

编程时,调用Regsvr32来注册,却不能正常执行。尤其是在Win7系统中,需要管理员身份才能运行。

使用下面的代码则能正常注册。

//注册
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 ProcAddrnil then
    begin
      CallWindowProc(ProcAddr,nDllAddr,0,0,0); 
      Result := True;
    end;
    FreeLibrary(nDllAddr);  
  end;                     
end;
 
 
//反注册
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 ProcAddrnil then
    begin
      CallWindowProc(ProcAddr,nDllAddr,0,0,0);
      Result := True;
    end;
    FreeLibrary(nDllAddr);  
  end;                     
end;
