CreateDirectoryView()

Here is some code I was working on to create a Directory View - please use as much as you want, and adapt it likewise, but I do request some sort of small credit (You don't have to, but it would be nice) and If you use the code, do tell me, as I am interested in how it could be used. It could be set to read a cirtain area only and get a level selector, there are many possiblities.

Anyway, do tell me what you think, I know it's slow, but I can't see any way of fixing that.

; Below are the two functions to add if you wish to use.

Function CreateDirectoryView(window,drive$,startx,starty,width,height,viewfiles)

main=CreateTreeView(startx,starty,width,height,window)
root1=TreeViewRoot(main)
folder=AddTreeViewNode(drive$,root1)

AddFolderContents(drive$,file$,folder,viewfiles)

End Function


Function  AddFolderContents(drive$,file$,folder,viewfiles)

dir=ReadDir(drive$+""+file$)

While MoreFiles(dir)

file2$=NextFile(dir)

If file2$ <> "." Then
If file2$ <> ".." Then 

If FileType(drive$+""+file$+""+file2$) = 2 Then

folder2=AddTreeViewNode(file2$,folder)

drive2$=drive$+""+file$

AddFolderContents(drive2$,file2$,folder2,viewfiles)

Else

If viewfiles=True Then folder2=AddTreeViewNode(file2$,folder)
