[HELP] Invoke InternetReadFile API

[Swellow]

I've tried almost everything to Invoke that API and I always failed...

I suceed with InternetOpen/InternetOpelUrl/InternetCloseHandle but not that one :/

Código [Seleccionar] Expandir

Private Declare Function InternetReadFile Lib "wininet.dll" (ByVal hFile As Long, ByVal lpBuffer As String, ByVal dwNumberOfBytesToRead As Long, lNumberOfBytesRead As Long) As Integer

        bDoLoop = InternetReadFile(hInternetOpen, strArray, Len(strArray), lNumberOfBytes)

Can anyone help please?

Thanks for your answer man but its not that that I want. I want to Invoke the API using CallAPIByName.
