This function should enable you to download any file from any url.



.... where 'from$' is the full url, and 'to$' is the full download path on your harddrive. The function returns a value of 0 if it succeeded, 1 if it failed.

You could also precompile it in hidden mode too, and execute it from your main application so that it runs in the background without affecting your main app.

It will probably trigger the user's firewall, asking for permission before it downloads anything - so any kiddies out there looking for ways to download code secretly onto a users machine - this isn't for you!

Handy, though it's cheating a bit using URLDownloadToFile. If you do it manually you can just store the data in memory rather than having to write it to a file, although this way is a lot quicker and may be desired.

Unless of course they use the command in Multisync that puts the program in Windows Firewall's allow list. Though a lot of people use another firewall I guess...

.... it's not cheating - it's making good use of available resources!

That is true.

Have you already realised that you can pass GET values to PHP scripts like this? I was thinking of making a plugin to do this the other day, forgetting that it could be done as simply as this.

I have passed GET values to a php script using the execute file command, and executing a url, which opens a browser window. I haven't figured out how to do it using urlmon, though - would be good if it could be done without opening a browser window. Any ideas? I hate the msdn website - I usually find it quite confusing!

Easy, just pass the same URL you would anywhere else:



POST values, on the other hand, require doing it a different way.

Oops - of course! Sometimes something is so simple you don't spot it!
