PathIsValid UDF - Check if the path is valid

[Guest]

Hello, I created a function that checks if the path is valid or not.

The reason I decided to write my own function  is because I found bugs in all the other functions that found here.

So i make my own function.

 

Example:

expandcollapse popup

$Path = "C:"
ConsoleWrite('Example 1 - check path "'&$Path&'"'&@CRLF)
If PathIsValid($Path) Then
    ConsoleWrite("Path is valid"&@CRLF)
Else
    ConsoleWrite("Path not valid"&@CRLF)
EndIf
ConsoleWrite(@CRLF)


$Path = "C:\"
ConsoleWrite('Example 2 - check path "'&$Path&'"'&@CRLF)
If PathIsValid($Path) Then
    ConsoleWrite("Path is valid"&@CRLF)
Else
    ConsoleWrite("Path not valid"&@CRLF)
EndIf
ConsoleWrite(@CRLF)


$Path = "CC:\"
ConsoleWrite('Example 3 - check path "'&$Path&'"'&@CRLF)
If PathIsValid($Path) Then
    ConsoleWrite("Path is valid"&@CRLF)
Else
    ConsoleWrite("Path not valid"&@CRLF)
EndIf
ConsoleWrite(@CRLF)


$Path = "C\"
ConsoleWrite('Example 4 - check path "'&$Path&'"'&@CRLF)
If PathIsValid($Path) Then
    ConsoleWrite("Path is valid"&@CRLF)
Else
    ConsoleWrite("Path not valid"&@CRLF)
EndIf
ConsoleWrite(@CRLF)


$Path = "C:\aaa"
ConsoleWrite('Example 5 - check path "'&$Path&'"'&@CRLF)
If PathIsValid($Path) Then
    ConsoleWrite("Path is valid"&@CRLF)
Else
    ConsoleWrite("Path not valid"&@CRLF)
EndIf
ConsoleWrite(@CRLF)



$Path = "C:\aaa\bbb"
ConsoleWrite('Example 6 - check path "'&$Path&'"'&@CRLF)
If PathIsValid($Path) Then
    ConsoleWrite("Path is valid"&@CRLF)
Else
    ConsoleWrite("Path not valid"&@CRLF)
EndIf
ConsoleWrite(@CRLF)



$Path = "C:\aaa\\bbb"
ConsoleWrite('Example 7 - check path "'&$Path&'"'&@CRLF)
If PathIsValid($Path) Then
    ConsoleWrite("Path is valid"&@CRLF)
Else
    ConsoleWrite("Path not valid"&@CRLF)
EndIf
ConsoleWrite(@CRLF)


$Path = "C:\a/aa\bbb"
ConsoleWrite('Example 8 - check path "'&$Path&'"'&@CRLF)
If PathIsValid($Path) Then
    ConsoleWrite("Path is valid"&@CRLF)
Else
    ConsoleWrite("Path not valid"&@CRLF)
EndIf
ConsoleWrite(@CRLF)


$Path = "C:\\"
ConsoleWrite('Example 9 - check path "'&$Path&'"'&@CRLF)
If PathIsValid($Path) Then
    ConsoleWrite("Path is valid"&@CRLF)
Else
    ConsoleWrite("Path not valid"&@CRLF)
EndIf
ConsoleWrite(@CRLF)


$Path = "C:\  \bbb"
ConsoleWrite('Example 10 - check path "'&$Path&'"'&@CRLF)
If PathIsValid($Path) Then
    ConsoleWrite("Path is valid"&@CRLF)
Else
    ConsoleWrite("Path not valid"&@CRLF)
EndIf
ConsoleWrite(@CRLF)


$Path = "C:\    aaa\bbb"
ConsoleWrite('Example 11 - check path "'&$Path&'"'&@CRLF)
If PathIsValid($Path) Then
    ConsoleWrite("Path is valid"&@CRLF)
Else
    ConsoleWrite("Path not valid"&@CRLF)
EndIf
ConsoleWrite(@CRLF)


$Path = "C:\aaa    \bbb"
ConsoleWrite('Example 12 - check path "'&$Path&'"'&@CRLF)
If PathIsValid($Path) Then
    ConsoleWrite("Path is valid"&@CRLF)
Else
    ConsoleWrite("Path not valid"&@CRLF)
EndIf
ConsoleWrite(@CRLF)



$Path = "C:\aaa          aaaa\bbb"
ConsoleWrite('Example 13 - check path "'&$Path&'"'&@CRLF)
If PathIsValid($Path) Then
    ConsoleWrite("Path is valid"&@CRLF)
Else
    ConsoleWrite("Path not valid"&@CRLF)
EndIf
ConsoleWrite(@CRLF)



$Path = "C:\aaa          aaaa    \bbb"
ConsoleWrite('Example 14 - check path "'&$Path&'"'&@CRLF)
If PathIsValid($Path) Then
    ConsoleWrite("Path is valid"&@CRLF)
Else
    ConsoleWrite("Path not valid"&@CRLF)
EndIf
ConsoleWrite(@CRLF)

Example + Code:

PathIsValid.au3

 

Enjoy!

I hope you find it useful!

Maybe this will give you some idea of how to get rid of the loop >> >_StringIsValid()

[Exit]

Nice try, ... but you flag some path as invalid, but they are valid.

"C:/" and "C:/" and "C:" and "C:/" are equal to "C:" and valid.
"C:aaabbb" is the same as "C:aaabbb"
"C:a/aabbb" is the same as "C:aaabbb"

Just try it in a CMD prompt.

Here a screenshot.

Interesting.

but i do not think it's critical bugs as I found in other functions.

"C:/" and "C:" and "C:/" are really not valid if i test it with windows explorer.

I get these messages:

http://prntscr.com/3fhone

http://prntscr.com/3fhosy

http://prntscr.com/3fhpbs

But "C:/" is unexpectedly working and you right about this case.

I tested also "C:aaabbb" (after i created the path) with explorer and the result is error.

but "C:aaa/bbb" is working..

So windows explorer (not cmd) also flag "C:/" and "C:" and "C:/" as not valid as my script.

only "C:aaa/bbb" and "C:/" are flaged as valid by windows explorer and not by my script.

I do not think it is critical to my case. You can fix it if you want

Maybe this will give you some idea of how to get rid of the loop >> >_StringIsValid()

 

Thank you.

Maybe I'll check it out.

I'd rather not fix what works.

Just because it works doesn't mean it's the right way and clearly your function needs a little bit of tweaking. Oh well.

C: is a valid path, yet this is flagged as invalid.

[guinness]

ConsoleWrite(_FilePathIsValid("C:") & @CRLF)

Func _FilePathIsValid($sFilePath, $sPattern = '*?|:<>"/')
    Return StringRegExp($sFilePath, '(?i)^[a-z]:([^\Q' & $sPattern & '\E]+)?(\\[^\Q' & $sPattern & '\E\\]+)?(\.[^\Q' & $sPattern & '\E\\\.]+|\\)?$') ; Not the author.
EndFunc   ;==>_FilePathIsValid

I fixed this bug.

Check Again

So please give an example if you want.

I see no reason to tweak this because it takes less than a quarter of a second..

You didn't upload/change anything on what's been posted, C: is still showing as invalid

This is strange. I downloaded the script again and I run it and this is my result:

 

Example 1 - check path "C:"

Path is valid

Example 2 - check path "C:"

Path is valid

Example 3 - check path "CC:"

Path not valid

Example 4 - check path "C"

Path not valid

Example 5 - check path "C:aaa"

Path is valid

Example 6 - check path "C:aaabbb"

Path is valid

Example 7 - check path "C:aaabbb"

Path not valid

Example 8 - check path "C:a/aabbb"

Path not valid

Example 9 - check path "C:"

Path not valid

Example 10 - check path "C:  bbb"

Path not valid

Example 11 - check path "C:    aaabbb"

Path not valid

Example 12 - check path "C:aaa    bbb"

Path not valid

Example 13 - check path "C:aaa          aaaabbb"

Path is valid

Example 14 - check path "C:aaa          aaaa    bbb"

Path not valid

 

I using autoit 3.3.10.2 .

what autoit version you are using? did you runned the script in your head?

So please give an example if you want.

I did.

I using autoit 3.3.10.2 .

First, it would be "ran the script in your head", and I'm not sure where you're from exactly, but in the U.S. even the properly translated question does not make much sense.

I also got the same result as the others on 3.3.10.2
