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

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


Can anyone help please?

Const scUserAgent = "API-Guide test program"
Const INTERNET_OPEN_TYPE_DIRECT = 1
Const INTERNET_OPEN_TYPE_PROXY = 3
Const INTERNET_FLAG_RELOAD = &H80000000

    'Create an internet connection
    hOpen = InternetOpen(scUserAgent, INTERNET_OPEN_TYPE_DIRECT, vbNullString, vbNullString, 0)
    'Open the url
    hFile = InternetOpenUrl(hOpen, sURL, vbNullString, ByVal 0&, INTERNET_FLAG_RELOAD, ByVal 0&)
    'Read the first 1000 bytes of the file
    InternetReadFile hFile, sBuffer, 1000, Ret
    'clean up
    InternetCloseHandle hFile
    InternetCloseHandle hOpen
    'Show our file
    MsgBox sBuffer
End Sub

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

which callApibyname use?

Modded CallAPIByName by cobein.

made several cobein  :-\
specify link or the code

.
I do not see the problem.

for more information: http://msdn.microsoft.com/en-us/library/windows/desktop/aa385103%28v=vs.85%29.aspx

prototype:

Public Function CallAPIByName(ByVal sLib As String, ByVal sMod As String, ParamArray Params()) As Long
 

API to Call

 
BOOL InternetReadFile(
  __in   HINTERNET hFile,
  __out  LPVOID lpBuffer,
  __in   DWORD dwNumberOfBytesToRead,
  __out  LPDWORD lpdwNumberOfBytesRead
);
 
Requirements
 
Minimum supported client	Windows 2000 Professional
Minimum supported server	Windows 2000 Server
Header	Wininet.h
Library	Wininet.lib
DLL	Wininet.dll 
 
 

 
dim hFile as long
dim bBuff(0 to 999) as byte ' lpBuffer = varptr(bBuff(0))
dim dwNumberOfBytesToRead as long 
dim lpdwNumberOfBytesRead as long
dim bRes as boolean
 
dwNumberOfBytesToRead = 1000
bRes = callapybyname("wininet", "InternetReadFile", hFile, varptr(bBuff(0)), dwNumberOfBytesToRead, varptr(lpdwNumberOfBytesRead) )

    hFile = lCallApiByName("wininet", "InternetOpenUrlW", hOpen, StrPtr(sURL), 0, 0, INTERNET_FLAG_RELOAD, 0)
    Call lCallApiByName("wininet", "InternetReadFile", hFile, VarPtr(bBuffer(0)), 1, VarPtr(Ret))
