date manipulation!

A question for you...
Well here are my scenario...

User is suppose to enter starting date: dd-mm-yyyy into a textbox provided and enter ending date: dd-mm-yyyy into respective textbox. The program would have to trace the path, dir based on the date entered.

My problems are how am I suppose to let my vb program to create folders consisting of all files from starting date to the ending date? pls advise..thanks

Errr...you want to enter a date and get VB to get all files that were created on that date and place them in another folder?

Woka

Take a look at some of these functions:
MsgBox Format(Now, "MM")
MsgBox Format(Now, "MMM")
MsgBox Format(Now, "MMMM")

Using these you can verify that the entered date is valid.
Also the IsDate(enteredDate) would be useful.


You can add to the dates with:
myDate = DateAdd("m", 1, Now)
which adds 1 month. You can also add hours, days or whatever.


Then the create a folder will need the MKDir function. And possibly the DIR() function to see if it exists already.



--------OR-----------
(if I understand your question another way around)
try these functions

VB Code:

sFile = Dir$(strDirToLookInto)
    Do
        If FileDateTime(sFile) "in the range that you want" Then
                CopyFile sFile,strDestinationFolder & "\" & sFile
        end if
        sFile = Dir$
    Loop

When you have some code almost working, come back for some more specific questions.

Not really...the user will have to enter 2 dates: one for start date and another for end date.
The path and directory for both date folders are located at
start date: C:\PG\CW\01-01-2001\ and
end date: C:\PG\CW\20-01-2001\ respectively.

I need to save all *.dat files from 01-01-2001 folder until 20-01-2001 folder into a A:\ drive. The A:\ will have to generate the sample output as shown below
A:\PG\CW\01-01-2001\a.dat
A:\PG\CW\01-01-2001\b.dat
A:\PG\CW\01-01-2001\c.dat
A:\PG\CW\02-01-2001\a.dat
A:\PG\CW\03-01-2001\a.dat
A:\PG\CW\04-01-2001\a.dat
......until
A:\PG\CW\20-01-2001\a.dat
A:\PG\CW\20-01-2001\b.dat
A:\PG\CW\20-01-2001\c.dat

Is it clear now? How am I suppose to tackle this problem?

I manage to create A:\PG\CW folder but unable to create date folder that the user specified.

Fyi Bck means backup...i need to do backup for the existing folders and files. Below are my snippet for creating folder.

---------------------------------------------------------------------------------
Public Sub PG_Md()

Dim InitPath, BckDir, DirFlag As String

'---------------------------------------------------------
'Initialise Variable
DirFlag = "N"

'Define Search Directory
InitPath = "A:\PG\"
BckDir = Dir(InitPath, vbDirectory)

'Search for PG\CW directory
Do While BckDir <> ""
If BckDir <> "." And BckDir <> ".." Then
If GetAttr(InitPath & BckDir) = vbDirectory Then
If BckDir = "CW" Then
DirFlag = "Y"
End If
End If ' it represents a directory.
End If
BckDir = Dir
Loop

' Create CW if not found
If DirFlag = "N" Then
MkDir "A:\PG\CW"
End If

End Sub
--------------------------------------------------------------------------------
Thanks!

To create the folders with the dates...

VB Code:

'(min_date is the lowest of the two dates, max_date is the highest)
 
Dim tmp_date As Date
 
  tmp_date = min_date
  Do While tmp_date <= max_date
    MkDir "A:\PG\CW\" & Format(tmp_date, "dd-mm-yyyy")
    tmp_date = DateAdd("d", 1, tmp_date)
  Loop

For the error handling on creating the folders there are two main methods - the one you have, and ignoring all errors (by having an extra line just before this code: On Error Resume Next ). In this case I think that your method would be better. (you would be better of making a function to do the Dir bit and MkDir if needed).

You will probably need to make use of the FSO, so add a reference to Microsoft Scripting Runtime.
You will need a process something like:

Code:

---

Set up and validate YourStartDate
Set up and validate YourEndDate
Set up the FSO
Set FolderBase to "C:\pg\cw"
For each thisFolder in FolderBase.Folders
  If thisFolder > YourStartDate
    If thisFolder < YourEndDate
        Check thisFolder is present on A:\PG\CW
        For each file in thisFolder.Files
            CopyFile file to A:\PG\CW & thisFolder
        Next
    End If
  End If
Next

---

Set up routines in VB to:
- enter and validate a date from the user.
- check a folder exists
- Create fodlers as required (see previous post)
- check a date is before or after another date

Thanks a lot..
As a new programmer, I still have doubts for your instructions...
What is FSO and what does it do?
As for your previous code..(the earlier one), it doesn't output the way it should. perhaps you can give me any extra advice...thanks

FSO = File Scripting Object. Allows you to do things with files, like stepping through every file in a folder, or every sub-folder in a folder. Its not strictly needed, but using it will be easier for you than trying to do recursion with DIR() functions.

Yes it does. But it might not output the way you want it to! :-)
Tell us which code, and what you need to be different, AND what you have tried so far so we don't duplicate your work.

Hello here is the attachment of my program, i have highlighted my questions with remarks....the bottom part. The top portion generally works well...
the bottom part, .... I can't seem to get the date right yet. please advise....thanks in advance
