Нашел в FAQ"e пример для поиска сетевых компьютеров написанный в Delphi. Пытаюсь подогнать его для использования в C++ Builder и никак не получается - при компиляции ругается на несоотвествие типов данных и т.п.
Поджскажите в чем моя ошибка?

THandle EnumHandle; TNetResource WorkgroupRS; TNetResource Buf[500]; Word BufSize; Word Entries; Word Result; WorkgroupRS.dwScope = 2; WorkgroupRS.dwType = 3; WorkgroupRS.dwDisplayType = 1; WorkgroupRS.dwUsage = 2; WorkgroupRS.lpRemoteName = &Workgroup[0]; WNetOpenEnum( RESOURCE_GLOBALNET, RESOURCETYPE_ANY, 0, &WorkgroupRS, &EnumHandle); // Вот здесь выдает ошибку /* [C++ Error] unetsearchclient.cpp(107): E2034 Cannot convert "unsigned int *" to "void * *" [C++ Error] unetsearchclient.cpp(107): E2342 Type mismatch in parameter "lphEnum" (wanted "void * *", got "unsigned int *") */ do { Entries =1; BufSize = sizeof(Buf); Result = WNetEnumResource( EnumHandle, Entries, &Buf, &BufSize ); // И вот здесь тоже /* [C++ Error] unetsearchclient.cpp(116): E2034 Cannot convert "unsigned int" to "void *" [C++ Error] unetsearchclient.cpp(116): E2342 Type mismatch in parameter "hEnum" (wanted "void *", got "unsigned int") [C++ Error] unetsearchclient.cpp(116): E2034 Cannot convert "int" to "unsigned long *" [C++ Error] unetsearchclient.cpp(116): E2342 Type mismatch in parameter "lpcCount" (wanted "unsigned long *", got "unsigned short") [C++ Error] unetsearchclient.cpp(116): E2034 Cannot convert "unsigned short *" to "unsigned long *" [C++ Error] unetsearchclient.cpp(116): E2342 Type mismatch in parameter "lpBufferSize" (wanted "unsigned long *", got "unsigned short *") */ if (Result == NO_ERROR&&Entries == 1) { Memo1->Lines->Add(AnsiString(Buf[1].lpRemoteName)); } } while (Entries!=1||Result!=NO_ERROR); WNetCloseEnum( EnumHandle ); //И здесь тоже ошибка /* [C++ Error] unetsearchclient.cpp(123): E2034 Cannot convert "unsigned int" to "void *" [C++ Error] unetsearchclient.cpp(123): E2342 Type mismatch in parameter "hEnum" (wanted "void *", got "unsigned int") [C++ Warning] unetsearchclient.cpp(125): W8004 "BufSize" is assigned a value that is never used */
