Hello, According to Melba23, one of the moderators in AutoIt, is a good practice to use this directive to check for syntax: #AutoIt3Wrapper_au3check_parameters=-d -w 1 -w 2 -w 3 -w 4 -w 5 -w 6 Reference: https://www.autoitscript.com/forum/topic/97052-au3-check-parameters/?tab=comments#comment-697751 So, when I use that directive in my script I get some warnings from WinHttp.au3 UDF. Thanks!
