Navigate window to import txt

[Macallan60]

Hello,



I need to import severla txt files daily with different names. The names of the files are are never the same. They are completely random.

I am hoping that there is a macro or vb code that will open a window that will alow me to navigate to the file location and allow me to choose the txt file. I already have the import specifications saved.

I am now using Access 2007 on WinXP.

thanks in advance, Kevin

Hi Paul,

Thanks for your fast reply. Sorry about all the typos above. I can't type worth crap.

What I would like to do is modify the code below to allow me to choose the txt file I need:

'------------------------------------------------------------
' Proc_1_macro_Run_Process
'
'------------------------------------------------------------
Function Proc_1_macro_Run_Process()
On Error GoTo Proc_1_macro_Run_Process_Err
DoCmd.SetWarnings False
DoCmd.OpenQuery "01 delete KBASE Table", acViewNormal, acEdit
DoCmd.SetWarnings False
DoCmd.TransferText acImportDelim, "KBASE Import Specification", "KBASE", "C:\Documents and Settings\williamsonk\My Documents\KBase FTP\447351.txt", False, ""

Proc_1_macro_Run_Process_Exit:
Exit Function
Proc_1_macro_Run_Process_Err:
MsgBox Error$
Resume Proc_1_macro_Run_Process_Exit
End Function

Please let me know your thoughts.

Thanks, Kevin

I understood what you wanted. You can use code from that link to get the path into a variable, then use that variable in the TransferText line.

[Macallan60]

Thanks for you help Paul. However, since I'm a Access newby, that code is way over my head. Sorry I bothered you.

[pbaldy]

No bother, and the code is pretty much copy/paste, with an example of how to use it. Dive in and get your feet wet. You won't learn how to swim without jumping in the pool. Post back if you have trouble.

Below is the code from the link. Where do I add the import specification and the table name?

You have it backwards. You don't add anything to their code. Just copy/paste it into a standard module. Then your code calls theirs:

  Dim strFilter               As String
  Dim strInputFileName        As String

  strFilter = ahtAddFilterItem(strFilter, "Text Files (*.txt)", "*.txt")
  strInputFileName = ahtCommonFileOpenSave( _
                     Filter:=strFilter, OpenFile:=True, _
                     DialogTitle:="Please select an input file...", _
                     Flags:=ahtOFN_HIDEREADONLY)

  DoCmd.TransferText acImportDelim, "KBASE Import Specification", "KBASE", strInputFileName, False, ""

Here's what I've done so far:
- I copied/pasted the large code in a module and called it module1
- Then I copied the code from your reply and called it module2
-When I double clicked on module2 from Access, a vb window opened.
-I clicked the green arrow button (Run sub/User form).
-A dialog box appeared called "Macro" and asked for a macro name.

What mistake have I made? Sorry, you are dealing with a VB stupid person here. First time I every touched it.

[pbaldy]

Given what you've described, I'd expect your code to be behind a button, though it could be in a module. Here's a primer:

http://www.baldyweb.com/FirstVBA.htm

If you want to test it in the module, place the cursor in the code and then click on Debug/Step Into.

[Macallan60]

I'm not using a form in the database (I'm assuming the command button is in a form). In the past, I use the macro to run all my queries by double clicking on the macro itself.

[pbaldy]

If you want to initiate it with a macro, make sure your code is a public function, then use the RunCode action to run it.
