Dir function

[pvbangera]

hi all,

in vb6, when i required list of all txt files in a directory, i used the following code:

DirArray(1) = Dir("c:\mydir\*.txt")
        For ArrCnt = 2 To UBound(DirArray) - 1
            DirArray(ArrCnt) = Dir() 'here's the problem with dir function
        Next

but in vb.net, the dir function is not working without the pathname. in my xp pc, which is my development pc, no error is generated. but in client pc, which is win 98 se, it shows the error.

pls guide, what to do?

regards,

prakash

Use the static Directory Class to get files with specific pattern .

Dim files() As String = IO.Directory.GetFiles("c:\", "*.txt")
        For Each file As String In files
            MessageBox.Show(file)
        Next

Hi,

Imports System
Imports System.IO

ListBox1.DataSource = Directory.GetFiles("C:\")

Have a nice day

[pvbangera]

What's the error message ?

[pvbangera]

it gives some error that 'you cannot use dir() function without pathname.

Umm , you mean it complains if you provided a variable instead of pathname ? I'm afraid I couldn't get it .

[pvbangera]

no, not like that. if i use dir() function without any arguments, then it shows error.

strPath = "c:\temp\*.txt"
strFile = dir(strPath) 'No problem
strFile = dir() 'Error occurs

strFile = dir() 'Error occurs

When you use it this way , what do you think dir() function would return ???????? .

You must specify path name .

[pvbangera]

my dear friend,

i need not tell u that in vb6 when u say

Text1 = dir("c:\*.txt")

it will return 1st txt file in the path and next time when u say

Text1 = dir()    'without any argument

it returns next txt file in the directory. i want to say that this is not working in vb.net.

i hope, i am clear.

eeh , Do you really have to use that function (which is basically for compatibility code with VB6) . Have you checked IO.Directory.GetFiles() function ??

well well! thank you for your information, but I think people knwo that hehe
my suggestion as well as others, dont use the dir() function, its just for backwards compatibility I believe. Try to only use the classes provided in the .NET framework (excluding the visualbasic compatibility crap). yulyos and Pirate already told you how to use them


btw pirate you're getting used to start your sentences with "eeh" too ha? I dont know where I got that habit from but it seems like it's getting into your too

[pvbangera]

eeh (me too)

my purpose was solved by pirate's 1st post. but i had a question after that which i guess u ppl forgot.

but just for info, anybody please tell me why the error was not thrown on xp pc, unlike win 98se.

i dont want to use dir() function anymore. just for info sake i want the answer for the above question. thats all

I don't know but it might be dumb enough if I say it has some issue with the OS and FS (NTFS vs FAT32) . I don't know what inside this function . I just check MSDN , and there's no note about supporting OS .
