Re: [Dev-C++] Network monitor - Question

[Per W. <pw...@ia...>]

DWORD GetIpNetTable(
  PMIB_IPNETTABLE pIpNetTable,  // buffer for mapping table
  PULONG pdwSize,               // size of buffer
  BOOL bOrder                   // sort by IP address
);

Are you setting your dwSize to the size of the buffer before calling
GetIpNetTable()? Else the call might overwrite the buffer, and thereby
destroy other variables in your program.
