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;
2. POPUP dialog mode with detailed info;
3. BANNER mode with simple popup window.

Plug-in recognizes Installer's Silent mode and this case hides any output (this feature requires NSIS 2.03 or later). 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.

Command line parameters (NSIS script)

InetLoad::load [/PROXY IP:PORT] [/USERNAME PROXY_LOGIN /PASSWORD PROXY_PASSWD]
[/NOPROXY] [/NOCANCEL] [/POST TEXT2POST] [/TIMEOUT INT_MS] [/SILENT TEXT2DISPLAY]
[/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.

/NOPROXY

Disables proxy settings for this connection (if any)

/NOCANCEL

Prevents download from being interrupted by user (locks Esc, Alt-F4, Cancel handling)

/POST

Sets POST http mode and defines text string to be used in the POST (http only). Disables auto re-get. No char replaces used (%20 and others).

/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). Sets TEXT2DISPLAY to 1006 control, if /silent "" - displays "InetLoad plug-in" default. 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 translating plug-in text in the POPUP or "old style" (NSISdl) modes (see Readme for parameters). In the BANNER mode text is also customizable.

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.
