hi

I have below statement in my code but for some reason the trap is not
catching the error. Any reason why ??

function CheckFolder()
{
trap
{
write-Host "[ Error ] " + $_ -foreground green
continue
}

test-Path "E:\Scripts\W:"


}
Greet

but you haven't error. Test-Path will never generate error and allways will
return True or False if only path not contains semicolon character in middle
(if semicolon is the last character, error will not generated and if
semicolon is the first character you will be promted for path). Check this:
[vPodans] test-path sdlkfvdsaflkdsfalkdsfasdkflwmdafa
False
[vPodans] test-path sdkjsad;
False
[vPodans] test-path sdkj;sad
False
The term 'sad' is not recognized as a cmdlet, function, operable program, or
script file. Verify the term and try again
..
At line:1 char:19
+ test-path sdkj;sad <<<<
+ CategoryInfo : ObjectNotFound: (sad:String) [],
CommandNotFoundException
+ FullyQualifiedErrorId : CommandNotFoundException

[vPodans] test-path ;sdkjsad

cmdlet Test-Path at command pipeline position 1
Supply values for the following parameters:
Path[0]:

so, if semicolon character is in path middle, then your Trap will works.

also error will be generated if path contains space. But if path is enclosed
in quotes, then any character inside will be accepted and True or False will
returned.

Apparently your default error action is to continue.
Try this.

function CheckFolder($name){
trap {
write-Host "[ Error ] " + $_ -foreground green
continue
}
test-Path $name -ErrorAction stop
}

Test-Path cmdlet generates an exception [RuntimeException] if the Path
parameter is not in a supported format.
In all over cases returned [Boolean], depending on whether specified
path is exist.
And, of course, you must set $ErrorActionPreference in Stop or
Inquire.
Try this variant:

function foo()
{
param($name)

try
{
if( Test-Path $name -ErrorAction 1 ){ $TRUE }
else{ throw( New-Object IO.DirectoryNotFoundException ) }
}
catch [Management.Automation.RuntimeException],
[IO.DirectoryNotFoundException]
{
$_.exception.message
}
}
