FTP with Harbour / MSVC / FWH issues

[TimStone]

I am running a program built with xHarbour / FWH that must do FTP processes. It works perfectly. I am using the .dll WININET and calling the functions:
INTERNETOPEN
INETCLOSEHANDLE
FTPGETFILE
FTPPUTFILE
INTERNETCONNECT

However, when I build using Harbour / MSVC / FWH, it appears to not recognize the WININET.dll because it gives me unidentified externals when trying to do run a successful build

These are all redefined as follows:

DLL32 FUNCTION InternetOpen( cAgent AS LPSTR, nAccessType AS DWORD, cProxyName AS LPSTR, cProxyBypass AS LPSTR, nFlags ;
    AS DWORD ) AS LONG PASCAL FROM "InternetOpenA" LIB iDLL

DLL32 FUNCTION INETCLOSEHANDLE( hInternet AS LONG ) AS BOOL;
    PASCAL FROM "InternetCloseHandle" LIB iDLL

DLL32 FUNCTION FTPGETFILE( hConnect AS LONG, cRemoteFile AS LPSTR, cNewFile AS LPSTR, nFailIfExists AS LONG, ;
    nFlagsAndAttribs AS DWORD, nFlags AS DWORD, @nContext AS PTR ) AS BOOL PASCAL FROM "FtpGetFileA" LIB iDLL

DLL32 FUNCTION FtpPutFile( hFTP AS LONG, cFileName AS LPSTR, cDestFile AS LPSTR,;
    n1 AS LONG, n2 AS LONG ) AS BOOL PASCAL ;
    FROM "FtpPutFileA" LIB iDLL

DLL32 FUNCTION InternetConnect( hSession AS LONG, cHost AS LPSTR, nPort AS LONG,;
    cUserName AS LPSTR, cPassword AS LPSTR, n4 AS LONG, n5 AS LONG,;
    n6 AS LONG ) AS LONG PASCAL ;
    FROM "InternetConnectA" LIB iDLL
 

iDLL is defined:
PRIVATE iDLL := LoadLibrary( "wininet.dll" )

As I said, this code is fine with xHarbour, but not Harbour. I've tried other approaches but all are problematic. Any ideas on this one ?

Please, check your message and fix it.

Took out the spurious part ..l

The following sample compiles and links fine here (of course it doesn't run):

#include "Fivewin.ch"


STATIC iDLL


FUNCTION MAIN()

    INTERNETOPEN()
    INTERNETCLOSEHANDLE()
    FTPGETFILE()
    FTPPUTFILE()
    INTERNETCONNECT()

    RETURN NIL


DLL32 FUNCTION InternetOpen( cAgent AS LPSTR, nAccessType AS DWORD, cProxyName AS LPSTR, cProxyBypass AS LPSTR, nFlags ;
    AS DWORD ) AS LONG PASCAL FROM "InternetOpenA" LIB iDLL

DLL32 FUNCTION INETCLOSEHANDLE( hInternet AS LONG ) AS BOOL;
    PASCAL FROM "InternetCloseHandle" LIB iDLL

DLL32 FUNCTION FTPGETFILE( hConnect AS LONG, cRemoteFile AS LPSTR, cNewFile AS LPSTR, nFailIfExists AS LONG, ;
    nFlagsAndAttribs AS DWORD, nFlags AS DWORD, @nContext AS PTR ) AS BOOL PASCAL FROM "FtpGetFileA" LIB iDLL

DLL32 FUNCTION FtpPutFile( hFTP AS LONG, cFileName AS LPSTR, cDestFile AS LPSTR,;
    n1 AS LONG, n2 AS LONG ) AS BOOL PASCAL ;
    FROM "FtpPutFileA" LIB iDLL

DLL32 FUNCTION InternetConnect( hSession AS LONG, cHost AS LPSTR, nPort AS LONG,;
    cUserName AS LPSTR, cPassword AS LPSTR, n4 AS LONG, n5 AS LONG,;
    n6 AS LONG ) AS LONG PASCAL ;
    FROM "InternetConnectA" LIB iDLL

Yes, it compiles and links fine ... but then when I run it, it can't find the function. Therein lies the problem.

[Enrico Maria Giordano]

Please, provide a reduced and self-contained sample of the problem.

I have it functioning with xHabour. I want to use Harbour + MSVC + FWH.

Another , how use ftp over TLS ?

hLib = LOADLIBRARY( "wininet.dll" )

hInternet := INETOPEN( "Anystring", 1, 0, 0, 0 )

hConnect := INETCONNECT( hInternet, "www.xtech.com.cn",21, "xxx@xtech.com.cn", "erp6.5", 1, 0,0 )

if !EMPTY( hInternet ).and.!EMPTY( hConnect )
