InternetGetLastResponseInfo when GetLastError returns ERROR_INTERNET_EXTENDED_ERROR

[martin]

If an FTP function fails, say FTPCommand, then I see what the last error is, and if it is ERROR_INTERNET_EXTENDED_ERROR (=12003) then I should be able to get the information on the error using

something like this

$LenErrMsg = stringlen($ErrMsg)

$res = DllCall('wininet','int','InternetGetLastResponseInfo','int_ptr',$Errnum,'str',$ErrMsg,'int_ptr',$LenErrMsg)

which doesn't work. It returns no error and doesn't change the $Errnum or $ErrMsg variables.

Does anyone know how to use InternetGetLastResponseInfo?

The info on InternetGetLastResponseInfo is here

The wininet.dll is not loaded into AutoIt at all times. You must open this DLL yourself and keep it open for the duration of your usage session. Otherwise, each function will load the DLL, do something if it can and then unload it again. This DLL keeps internal state data. When the DLL is unloaded, this data is lost.

Yes, thanks Valik. I should have mentioned that I have already done this in my script like this

Func onautoitstart()

$hDll = DllOpen("Wininet.dll") ;have to do this for the ftp routines to work

if $hDll = -1 then

msgbox(0,'Error','Could not open WIninet.dll')

exit

EndIf

EndFunc

Func onAutoitExit()

if $connected then _FTPClose($Open)

if $hDll <> 0 then DllClose($hDll)

EndFunc

Since the script is a special FTP client this seemed like e reasonable approach to me.

All the other FTP functions I use work OK. I can copy filesand directories from the server, I can move files and directories on the server, but if I try to delete a directory I will get an error if the directory is not empty. By checking the error I intend to recursively empty the contents of the directory if needed and then delete it. The problem is I can't get the information on the error using InternetGetLastResponseInfo. So I imagine I am doing the wrong thing with the call to wininet.dll. Am I correct in using 'str' for a pointer to a string?

DllCall('wininet','int','InternetGetLastResponseInfo','int_ptr',$Errnum,'str',$ErrMsg,'int_ptr',$LenErrMsg)

Bumped to try again
