List contents of a directory/folder in Powerbuilder.

Hi there.
I want a way to retrieve a list of all the files in a chosen directory or folder.

Pretty much any format will do, although something like an array of filenames and metadata such as dates would probably be the best.

The overall goal will be to generate a list of .sql files in \\server\folder\ and read the contents of each file so they can be executed against a database.

Using a Windows API call or whatever is fine. I am using Windows 2000.

Thank you for your time.

That does what I want.

Not perfect, since it requires a visual object and bit of playing around, but good enough.

In case anyone else cares, this quick and dirty code (below) will read the first file name. You can adjust it to loop through lb_1.TotalItems() to give you all the filenames.

uint li_filetype
string ls_file_pattern

li_filetype=39
ls_file_pattern = "\\server\share\"
lb_1.Reset ()
if lb_1.DirList ( ls_file_pattern, li_filetype ) then
      lb_1.SelectItem (1)
      //Messagebox ("First item is:", lb_1.SelectedItem ())
else
      Messagebox ("Can't read from:", ls_file_pattern)
end if

In all the years I've been working with pb, I have never seen that function! Probably because I don't use listboxes normally.

Dear Friend,
Try out this, Ive written and used for updating the application at the client system, by a single click of button, which has this following code.

Declare this API-Function in Application's Global Function Declaration Area

Function boolean CopyFile (string lpExistingFileName, ref string lpNewFileName, boolean b) Library "KERNEL32.DLL" Alias for "CopyFileA"

SetPointer(HourGlass!)
String ls_source, ls_dll, ls_pbd, ls_app, ls_all, ls_destination
String ls_path
String ls_complete_path

ls_pbd = '\\souce_system\spts_test\*.pbd'
ls_path = '\\source_system\spts_test\'
ls_destination = "C:\Spts\"

ddlb_dir_details.DirList(ls_pbd, 0)

If ddlb_dir_details.TotalItems() > 0 Then
For ii_row = 1 to ddlb_dir_details.TotalItems()
is_source_file_name = ddlb_dir_details.Text(ii_row)
ls_destination = ls_destination + is_source_file_name
is_source_file_name = ls_path + is_source_file_name
CopyFile(is_source_file_name,ls_destination,False)
SetNull(ls_destination)
SetNull(is_source_file_name)
Next
Else
MessageBox("Error","Copying Default Pbds Failure")
Return
End IF

with the slight modification to this code, you can get the list of files to the list box.

after getting the list of files, you can take the selected file and continue as

String ls_search
ls_search = "c:\abc.txt"
if FileExists(ls_search) then
ls_file = ls_file_2
string ls_shortpath, ls_file_contents
long ll_max_length
ll_max_length = 255
ls_shortpath = space(ll_max_length)
long ll_length
//windows API to get the dos-name(short name) and path if you know the window name
ll_length = GetShortPathName (ls_search, ls_shortpath, ll_max_length)
Integer li_FileNum
//Check out to find the file exists before proceeding, you can use ls_search(window name) or
//ls_shortpath(Dos Name) as you need
li_FileNum = FileOpen(ls_search,StreamMode!,Read!,LockWrite!)
//if exists aplly the wite lock to it
IF li_FileNum > 0 THEN
FileRead ( li_FileNum , ls_file_contents )
FileClose (li_FileNum)
End If
End IF

All the best,
