A loop in a Sub - 3/14/2008 7:29:28 AM

I am having trouble constructing a loop in this sub, or figuring out a way to do this. This is what I am trying to do. Inside the C:\Windows\Somefolder are a number of subfolders and the names of the subfolders are random, only the file names are known (and there are way more than 2). Hence the recurse.
The problem with the code below is that if the file named TEST.DLL is found the script ignores the TEST2.DLL file and ends out of the Sub. Of visa-versa. If the files are found in the same Subfolder, then there is no problem. But if the files are located in different Subfolders, then the sub ends. I'm out of ideas, so any help would be greatly appreciated.

Your script is only going one level deep...you need to call the sub for each subfolder if you want it to find more....

you could also write what you have now like this...

Thanks for your suggestion. Your version is better written than mine.

I only need it to go one level deep in C:\Windows\Somefolder. There are a number of Subfolders, but none of the Subfolders have Subfolders of their own, only files.

I was hoping to be able to do this without recalling the sub a number of times.

"I was hoping to be able to do this without recalling the sub a number of times. "

Why?

If there are 10 or 15 files in 10 random subfolders under C:\Windows\somefolder then that would require rewritting the sub 10 to 15 times

Actually no it would not. That is the whole point to recursion. Search the forim for examples of recursion.

I thought my script was a recursion.

Thank you

I will keep looking

Your code is an iteration. An iteration does exactly that, it iterates through the items in a collection. A recursion is an iteration that calls itself for some or all of the items in a collection. So in pseudo-code here is an example of folder recursion:

RecurseFolder RootFolderName

Sub RecurseFolder(strFolderName)
   Do something with the files in the folder
   For each sub-folder in the folder
        Call RecurseFolder Sub-Folder Name
   Next
End Sub

So what will happen is that this would do something to all the files in all the folders in a folder tree no matter how deep the tree goes.
