hey, I have a script that I want to use a conditional on to determine how to execute it. I want to have WScript.Arguments(1) IsNull int he script to check whether a 2nd argument was passed to the script from the command prompt. I have tried several variations and keeping getting syntax error messages or "Object is required"
I have tried IsEmpty(), IsNull(), Wscript.Argument(1) Is Null. I have passed the contents of wscript to x then used the functions on x and checked if it = '' but keep getting problems. SOmetimes the condition is ignored and the script executed anyway.
Does anyone know how to check if an argument is null or empty?
I did not post the code as I do not really think it is specific to my code. I want to know if it could be done in general, so I could use it in this code and future scripts. Even basic code like:
If IsNull(WScript.Arguments(1)) Then WScript.Echo "Hello" Else WScript.Echo "Goodbye" End If
I hope you can see what I mean by this. I tried IsEmpty in place of IsNull and ='' but got nothing.
I have googled this and found nothing to help me either.
I haven't tried count, never even thought of that! Though it may work in this instance, I would stil like to know if anyone knows a method similar to the one I have shown above.
WScript.Arguments is an array (for all practical purposes), that contains the space delimited arguments from the command line. If there are no parameters, the array will be empty:
- remember VBScript arrays are zero-based. Of course it can't be 0, null, or empty, because then it couldn't be in the array. In general: passing n arguments/options will result in an array of Count/Length == n with n non empty strings (Len(WScript.Arguments( i ) > 0) accessible via index 0 ... (n-1).
