Table locked when trying to update via code called by a form

[gilly]

I am trying to update a database table via a command button on the main form, that uses tabbed sub forms.

The database gets its data from paradox data tables copied our company's
third-party software. These table files are copied from one location to another to stop the paradox database from locking up and giving me errors during the import process of this database. I then link to these files at a pre-determined location on a local computer hard drive.

When I try to run the code below I get the error about the table being
locked by a user or process. As you can see I have tried adding a pause
incase the files are still being copied but this does not seem to be the
problem.

I have used a msg box to confirm that the copying process has completed before starting the make query, but the same error comes up after I click ok.

Can anyone suggest anything else.

As you can see from the simplicity of the code below I am a beginner so take it easy on me, by not taking knowledge for granted.

code:
------------------------------------------------------------

Dim response
Dim stDocName As String
Dim stLinkCriteria As String


response = MsgBox("Are you sure that you want to update xxx with Customer
data from xxx?", vbYesNo, "Perform Update")
If response = vbYes Then

‘pause software to let any pending work to be completed
Sleep (5000)

‘close active form
DoCmd.Close

‘close all active forms
Do While Forms.Count > 0
DoCmd.Close acForm, Forms(0).Name
Loop

‘pause software to let any pending work to be completed
Sleep (30000)

‘delete existing file
Kill "c:\folder\file\ DATA.DB"

‘replace with new file
FileCopy "J:\Folder\new_DATA.DB", " c:\folder\file\ DATA.DB "

‘pause software to let any pending work to be completed
Sleep (40000)

DoCmd.SetWarnings False


stDocName = "Make_DATA"
DoCmd.OpenQuery stDocName, acNormal, acEdit

‘pause software to let any pending work to be completed
Sleep (35000)

stDocName = "Make_DATA_SUMMARY"
DoCmd.OpenQuery stDocName, acNormal, acEdit

‘pause software to let any pending work to be completed
Sleep (35000)

stDocName = "qry_Update_ Status"
DoCmd.OpenQuery stDocName, acNormal, acEdit

‘pause software to let any pending work to be completed
Sleep (35000)

‘open up main form when finsihed
stDocName = "main-form"
DoCmd.OpenForm stDocName, , , stLinkCriteria

DoCmd.SetWarnings True


Else
End If

How are you importing the data?

I see you running some "make table" queries, but no way to import the data. What do the queries look like?

 

[gilly]

I have created links to the paradox data files in Access and then reference these linked tables in the query using just a standard make table query syntax.

Cracked it

Someone suggested to me that I should SQL statements instead of calling Access-built queries, but this didn't help. Instead of deleting and rebuilding the tables via an Access make-table query I used queries to delete the data and append the new data into them.
