MadCoder Posted May 24, 2010 Share Posted May 24, 2010 I creating a small self update downloader for our out sourced beta testers and I need to check wheither a file exist and if so delete it before downloading the latest day's build. Where would I start? Link to comment Share on other sites More sharing options...
taietel Posted May 24, 2010 Share Posted May 24, 2010 (edited) This should do it: If FileExists("FilePath\file.ext") Then FileDelete("FilePath\file.ext") ;code for download Else ;place your code for download EndIf Edited May 24, 2010 by taietel Things you should know first...In the beginning there was only ONE!

jchd Posted May 24, 2010 Share Posted May 24, 2010 That may fail flat on its nose and duplicates the download part uselessly. Always check for errors! If FileExists("FilePath\file.ext") Then Local $ret = FileDelete("FilePath\file.ext") If Not $ret Then ; inform user of error and exit EndIf EndIf ; your code for download This wonderful site allows debugging and testing regular expressions (many flavors available).

taietel Posted May 24, 2010 Share Posted May 24, 2010 @jchd You're right: If the file cannot be deleted then error (I didn't thought at that!). Then if it's ok, go to download. It's good to learn from mistakes! Thanks jchd! Things you should know first...In the beginning there was only ONE! And zero...

jchd Posted May 24, 2010 Share Posted May 24, 2010 You're welcome. It's important writing correct and robust simple code: not only is it important per se, but it also greatly help when you're into more complex pieces of software. If you don't force you early into good habits, you're easily lost when things get more involved. This is completely orthogonal to the language and has even broader applications than just languages and computers.
