Q: Executing a FTP-command through WinInet/Win32?
M. S. Mortensen
-I am using MFC to communicate with a FTP-server. I can do the exact same
thing by addressing WinInet directly.
The FTP-server, which I address, has special capabilities; I need to execute
a FTP-command, which –as seen from the regular FTP-command-line
client-program- is a command like ”quote xxx”. This puts the server in a
special state, which I need for uploading and downloading files correctly.
Now, how do I do this? I actually found documentation for a call within
WinInet with a description like this:
INTERNETAPI BOOL WINAPI FtpCommand(HINTERNET hFtpConnect,
BOOL fExpectResponse,
DWORD dwFlags,
LPCTSTR lpszCommand,
DWORD dwContext);
As part of the description, it actually says:
LpszCommand
A string holding an FTP command. For example, "PWD \r\n".
Great! –I can just put my ”quote ...” command in there!?
No, the downside is – the documentation says Windows CE 2.0+. Argh! I need
*exactly* this, but for Windows 9x/NT.
I looked into my VC++ 6.0 into Wininet.h – it does not have the FtpCommand
call. However, I have an older Wininet.h residing on one of my disks (I
guess it is a leftover from my VC++ 5.0 installation...!?), and this *does*
contain the FtpCommand call, it seems... Hmm?
Can anyone help me on this? Is there a call like FtpCommand, which I can
used to execute the command in a simple way? Or am I forced to grab the
TCP/IP socket directly and construct the byte sequence for executing the
command? In the later case, have you got any idea on how to do this?
Help greatly appreciated!

martin...@my-deja.com
to a IBM-mainframe. Ihave found the exact layout at a webpage from
microsoft namely:
http://msdn.microsoft.com/workshop/networking/wininet/reference/function
s/FtpCommand.asp
Using this layout I could use the PWD command as you found in your
documentation, but alas when I tried the "quote site pquan=100" (to set
the primary allocation quantity on the mainframe) I got a command
unknown. When using this command directly on a mainframe to mainframe
FTP-session, this works just fine. Maybe someone else can shine a light
on this.
I hope any of this helps.
Kind regards,

Actually, I have now made the thing work; I can now execute my "quote xxx"
command!
It is a bit tricky, though. Without a updated wininet.h and wininet.lib, I
hack'et the call by GetProcAddress'ing and type-casting to the
function-pointer to match the description. I had a number of problems, but
at last, when I inspected the result of GetLastResponseInfo, it came up with
a variant of "'QUOTE xxx' command unknown"-text. I did NOT write the command
in uppercase - *someone* does some interpretation on this! This lead me to
try "quote quote xxx" by manual FTP. The server responded with the same
text - Aha! So with just the "xxx" as the command, the FTP-server received
the "quote xxx".
I have not tried with e.g. "pwd" as command - but I am kind of believing,
that it is not possible to use such a non-quote command, as the CE version
of the FtpCommand shows as an example... Hmmm?
Anyway, I got it to work!
Now for a new question:
My code is to run within an organisation, where it is absolutely out of the
question to upgrade to IE5. Among other things, it is politics.
==> Can I update the Wininet.dll manually??? <==
Looking at Wininet.dll, it may depend of up to seven other dll's (seven on a
NT4 system; on a Win95 system, there are two dll's less). From guessing, I
would expect that at least shlwapi.dll also has to be updated.
Can anyone tell, if it is possible to manually update the wininet.dll
*including* all dependencies - both on NT4 and Win95 systems?? I hope -but
would no be surprised if not- that I can update dll's without updating other
parts of the system...!
Does anyone have insight into this???
Regards,
Morten S. Mortensen.
