Description

MS WinInet API based plug-in for http and ftp downloads with better proxy support (compare to NSISdl plug-in). Command line may include few URL/File pairs to be downloaded. Plug-in supports 3 "download in progress" display modes:

1. old NSISdl style - additional embedded progress bar and text on the INSTFILES page; # POPUP dialog mode with detailed info; # BANNER mode with simple popup window.

Plug-in recognizes Installer's Silent mode and this case hides any output. Program implements simple re-get functionality - host reconnect and download from current position after short pause. NSISdl code fragment was used for progress bar displaying in the "old style" mode. Requires NSIS 2.03 or later.

Command line parameters (NSIS script)

InetLoad::load [/PROXY IP:PORT] [/USERNAME LOGIN /PASSWORD PASSWD]
[/TIMEOUT INT_MS] [/SILENT] [/RESUME RETRY_QUESTION]
[/POPUP PREFIX | /BANNER CAPTION TEXT] [/TRANSLATE LANG_PARAMS]
URL1 local_file1 [URL2 local_file2 [...]] [/END]

/PROXY

Overwrites current proxy settings, not required in most cases. IE settings will be used by default.

/USERNAME

Proxy username (http only).

/PASSWORD

Proxy password (http only). For server (http/ftp) authentication it is possible to use URL encoded name and password, for example http://username:password@nsis.sourceforge.net.

/TIMEOUT

Sets INTERNET_OPTION_CONNECT_TIMEOUT, milliseconds, default - IE current parameter value.

/SILENT

Key hides plug-in' output (both popup dialog and embedded progress bar). Not required if 'SilentInstall silent' mode was defined in script (NSIS 2.03 option).

/RESUME

On the permanent connection/transfer error instead of exit first displays message box with "resume download" question. Useful for dial-up connections and big files - allows user to restore connection and resume download. Default is "Your internet connection seems to have dropped out!\nPlease reconnect and click Retry to resume downloading...".

/POPUP

Mode displays detailed download dialog instead of embedded progress bar. Very useful in .onInit function (i.e. not in Section).

/BANNER

Displays simple popup dialog (MSI Banner mode) and sets dialog CAPTION ("NSIS Installer - InetLoad" is default) and TEXT (up to 3 lines using $\n).

/END

Allows to limit plug-in stack reading (optional, required if you stores other vars in the stack).

/TRANSLATE

Allows to translate plug-in text in the "old style" mode (see Readme for parameters). == Examples ==

InetLoad::load "http://dl.zvuki.ru/6306/mp3/12.mp3" "$EXEDIR\12.mp3" \
               "ftp://dl.zvuki.ru/6306/mp3/11.mp3" "$EXEDIR\11.mp3"
Pop $0

InetLoad::load /BANNER "" "Cameron Diaz download in progress..." \
"http://www.dreamgirlswallpaper.co.uk/fiveyearsonline/wallpaper/Cameron_Diaz/camerond09big.JPG" \
"$EXEDIR\cd.jpg"
  Pop $0
  StrCmp $0 "OK" dlok
  MessageBox MB_OK|MB_ICONEXCLAMATION "Download Error, click OK to abort installation" /SD IDOK
  Abort
dlok:
  ...

Plug-in returns "OK" string if successful, error description string if failed (see included InetLoad.cpp file for a full set of status strings). Usage and result processing samples are included to the package.
