Try-Catch-End Try in VBScript doesn’t seem to work
Handling Errors A sort of an “older style” of error handling is available to us in VBScript, that does make use of On Error Resume Next. First we enable that (often at the top of a file; but you may use it in place of the first Err.Clear below for their combined effect), then before … Read more

Getting current directory in VBScript

You can then use string manipulation (jscript example) : scriptdir = WScript.ScriptFullName.substring(0,WScript.ScriptFullName.lastIndexOf(WScript.ScriptName)-1) Or get help from FileSystemObject, (vbscript example) : scriptdir = CreateObject(“Scripting.FileSystemObject”).GetParentFolderName(WScript.ScriptFullName)
