Using or creating a ppp network connection
Post by acexbe on Feb 4^th, 2011, 09:21am

I need to transfer files using ftp through a serial ppp connection.
I created a new network connection and set it up as ppp.

The transfer works ok (see Wiki: Uploading files to an FTP server and MSDN WinINet).

But I have to start the ppp connection first.
Is there a possibility to start a preconfigured network connection (in this case the ppp one)?
Or even better, would it be possible to handle the creation and startup of a ppp in software.

Thanks,

Manuel

Can you configure the PPP subsystem to connect on demand?

No, I have to login each time.

Hello, I found the system command to start the ppp-connection, its "rasdial".
Here are 3 ways to do it. (thanks to the BB4W documentation)

1) REM execute the systemcommand
REM last parameter: 1=cmd visible 0= cmd not visible
REM no exit info
REM BB4W does not wait for the command

SYS "ShellExecute",@hwnd%,0,"rasdial", "name_of_ppp_connection ppp_password","c:",0


2) REM do systemcommand with visible cmd screen
REM gives the exit info
REM BB4W does not wait for the command



program$="name_of_ppp_connection ppp_password"
PRINT"Command started"


F%=OPENOUT"RUN.BAT"
PRINT#F%,program$:BPUT #F%,10
PRINT#F%, "ECHO %ERRORLEVEL% > EXITCODE.TXT":BPUT#F%,10
CLOSE#F%
*RUN RUN.BAT
F%=OPENIN"EXITCODE.TXT"
INPUT #F%,exitcode$
CLOSE#F%
exitcode%=VAL(exitcode$)
PRINT"Exit code= ";exitcode%


3) REM do systemcommand invisible
REM returns the exit info
REM waits until the command is executed


exitcode%=FNexecuteandwait("rasdial","name_of_ppp_connection ppp_password","c:",0)
PRINTexitcode%
IF exitcode%=0 PRINT"Connected"
IF exitcode%=623 PRINT"Wrong connection name"
IF exitcode%=691 PRINT"Wrong username or password"
IF exitcode%=777 PRINT"No serial connection"
WAIT 400
exitcode%=FNexecuteandwait("rasdial","PPP /disconnect","c:",0)
PRINTexitcode%
IF exitcode%=0 PRINT"Disconnected"

END



DEF FNexecuteandwait(prog$,parm$,cdir$,show%)
LOCAL sei{}, res%
DIM sei{cbSize%,fMask%,hwnd%,lpVerb%,lpFile%,lpParameters%,lpDirectory%,nShow%, \
\ hInstApp%,lpIDList%,lpClass%,hkeyClass%,dwHotKey%,hIcon%,hProcess%}
prog$ += CHR$0
parm$ += CHR$0
cdir$ += CHR$0
sei.cbSize% = DIM(sei{})
sei.fMask% = 64 : REM SEE_MASK_NOCLOSEPROCESS
sei.hwnd% = @hwnd%
sei.lpFile% = !^prog$
sei.lpParameters% = !^parm$
sei.lpDirectory% = !^cdir$
sei.nShow% = show%
SYS "ShellExecuteEx", sei{}
IF sei.hProcess% = 0 THEN = 1067
REPEAT
SYS "WaitForSingleObject", sei.hProcess%, 100 TO res%
UNTIL res%<>258 : REM WAIT_TIMEOUT
SYS "GetExitCodeProcess", sei.hProcess%, ^res%
SYS "CloseHandle", sei.hProcess%
=res%

Solution 3 is the way to do it.

Regards,

Manuel
