Hi all - hope someone can help I dont know where to start.I've got a cmd button that imports data from a excel sheet - that actual code is working fine, however when it runs it causes Access to freeze.
The data in imported correctly - so it must complete the process but Access locks up and has to be ended via task manager.
Any one got any clues why this is happening and how I can stop it?
This is an Access 97 database running mainly on NT and 2000
Code:
Private Sub LoadActualsDataButton_Click() On Error GoTo Err_LoadActualsDataButton_Click
' This procedure performs a two file match between the Actuals table (the Master file) and ' The Actuals spreadsheet file (the Transaction file).
'
' Keys : Study Code|Work Package|Period
'
' If the Master key < Transaction key then
' Read the next Master record.
' If the Transaction key > Master key then
' Add the transaction record to the Master file
' Read the next Transaction record.
' If the Master key = Transaction key then
' Update the value on the Master record with the value on the Transaction record
' Read the next Master Record
' Read the next Transaction record.
'
' End of File processing
' At End of File on the Master file, set the Master key to "ZZZZZZ"
' At End of File on the Transaction file, set the Transaction key to "ZZZZZZ"
' Continue processing until both keys are equal to "ZZZZZZ"
