RE: C++ Program on PC execute an ILE program on the iSeries

[Vern Hamberg <vhamberg@xxxxxxxxxxxxxxxxxxxxxxxxx>]

It's almost impossible NOT to have CA (iSeries) Express on your PC these 
days, what with Ops Nav in the mix. So you probably have OLE/DB and ODBC 
already installed. You can also use any ODBC or OLE/DB provider, such as 
Hit Software. The trouble with CAE ODBC is, you have to install the whole 
blame thing, even on machines where all you want is ODBC. At least, it used 
to be. If you use something else, such as Hit, that's all you install. And 
direct calls are part of ODBC or OLE/DB.

Otherwise, CAE does have a lot of ActiveX stuff that's usable from any 
development tool that can use them, such as MS VB, VC++, Delphi, etc. You 
need to install the Toolkit option of CAE to get the libraries and headers, 
etc. The stuff mentioned below is part of this.

If you dare open up the iSeries, you can start the rexec server on the 
iSeries and then use rexec from the PC - STRTCPSVR *REXEC starts the 
server, then use

rexec hostname -l username command-string

to run the command. You'll be prompted for your password. I don't remember 
if there's a way to get the password filled in - I think Unix version have 
a file for this. If there is interactive output, it'll be displayed in your 
command prompt (you have to be in a command prompt to put in the password). 
C++ might end up starting the command prompt, don't know.

Finally, the "quote rcmd" subcommand of ftp can be used. You can build a 
script for this that can contain user id and password (bad security) or it 
can be built by the C++ program on the fly. C++ could run FTP using this 
script. Drawback is lack of control and feedback. There is an FTP type lib 
you can reference, that you might be able to run individual subcommands 
with, getting response codes or errors, but it's not really friendly. 
Delphi has a better one. There are other socket things that could be used 
effectively to the rexecd port, too.
