Подключение lcomp.dll - VB

Формулировка задачи:

Уважаемые гуру в программировании помогите горю.В VB6 новичёк . Есть плата ввода/вывода на PCI шину и lcomp.dll с одной функцией (CreateInstance),есть примеры на C++ и Pascal , но я в них ни чего не смыслю.Может кто поможет c переводом на VB6.

 //////////////////////////// Это пример на С++ - Create cpp. //////////////////////////////////////
 
 CREATEFUNCPTR CreateInstance;
 HINSTANCE  CallCreateInstance(char* name)
 {
 HINSTANCE hCoponent=::LoadLibrary(name);
  if (hComponent==NULL);
 {
 return 0;
 }
 CreateInstance=(CREATEFUNCPTR)::GetProcAddress(hComponent,"CreateInstance");
  if (CreateInstance==NULL)
 {
 return 0;
 }
 return 1;
 }
/////////////////////////////////// Это реализация //////////////////////////////////////

trace("Get IUnknown pointer");
 CallCreateInstance("lcomp.dll");
 LUnknown* pIUnknown=CreateInstance(slot);
 if (pIUnknown ==NULL)  {trace("CallCreateIstance  failed") ; return 1;)
 trace("Get IdaqLDevice interface")
 IdaqLDevice* pI;
 
 HRESULT hr=pIUnknown->QueryInterface(IID_ILDEV,(void**)&pI);
  if (! SUCCEDED(hr)) {trace("Get IdaqLDevice failed"); return 1;}
 trace ("IdaqLDevice get success");
 trace("Free IUnknown");
 pIUnknown->Release();
 
 pI->OpenLDevice();
 pI->LoadBios("XXX");
