I want to check if the link is exists orno

is there any  function or a way to  do this?
Thanks in advance

InetGetSize() returns 0 if the file does not exist (or is empty, for which you can check that @error is non-zero).

Hello.

 

As stated in the help file, some servers do *NOT* return the file size, IIRC then the result is ZERO as well.

 

Not all servers will correctly give the file size, especially when using a proxy server.

 

If the returned size is > 0, the file should exist.

 

if not, you could just *START* the download to check with InetGetInfo(), if its download could be started, then abort it.

 

See help file for INetGet()

 

Notes about the "background" Parameter

By default the function waits until the download has finished before returning. If the background parameter is set to $INET_DOWNLOADBACKGROUND (1) the function returns immediately and the download continues in the background. The function InetGetInfo() can be used to check the status of the download. It takes the handle returned from InetGet().

Multiple downloads are supported if they are started in background mode.

To abort a download call InetClose() and pass it the handle returned by InetGet().

By default AutoIt forces a connection before starting a download. For dial-up users this will prompt to go online or dial the modem (depending on how the system is configured). The options value $INET_FORCEBYPASS (16) disables this behavior. Disabling the behavior can be useful for persistent connects (Broadband, LAN). However, it is also required to work around certain issues in Windows Vista and Windows 7.

Regards, Rudi.

@rudi, thanks for the heads-up. can you test what @error you get in that scenario from FileGetSize()?

Hello orbs,

Hm, currently I have no URL handy to check. I'll bookmark this and post an update, when I come across a download *NOT* presenting the final file size in the download list of IE/FF/Chrome.
