阅读更多关于 How to show progress on status bar when running a sequence of queries in MS Access

I have a macro in MS Access 2010 in Windows 7 which runs a sequence of quite slow Make Table and Update queries. I want it to show on the status bar which query it is running, as the usual message "Run query" does not give the query name. I have written the following VBA: Function RunQueryAndReportStatusWithMsgBox(QueryName As String) Dim RetVal As Variant On Error GoTo ErrHandler PutStatusBarBack MsgBox "About to run query" Application.Echo False, "Executing " & QueryName & " ..." DoCmd.OpenQuery QueryName, acViewNormal, acEdit On Error GoTo 0 Exit Function ErrHandler: Select Case Err Case

I have an Access 2010 database with all tables linked to SQL Server 2014 tables. I have an Excel 2010 (.xlsx) file (though it starts as a .csv, and I could leave it that way), that I need to import into a SQL Server table via VBA code. I know that there are import tools available to do this, however, I have 20+ XLS files per month to import, and would rather have an automated method of doing this. All my VBA code resides in the Access database, and all the examples of VBA code I've been able to find are for pushing data from Excel (i.e. the code is in Excel) not pulling from Access (i.e. the

Does anybody have an further details on this? For example, can they created in code (ACEDAO, SQL DDL, etc)?

阅读更多关于 How do I create copies of CurrentDb using VBA

问题 I need to create copies of the CurrentDB using VBA (approx. 12 copies). The copies need to be clones of the master database containing all the same forms, queries, etc. except only a limited dataset. DoCmd.CopyDatabaseFile seems to be made for this, but only works if you are using it to copy the DB to an MS SQL Server.

Is there a way to do this using either a query or VBA code? 回答1: Here is a snippet of VBA code I used to call a DB2 stored procedure. The same technique should work for any

问题 Just getting to grips some VBA (this stuff's new to me so bear with us!)

I'm then going to use this grouped list as way of cycling through the same query again, but passing through each unique entry as a filter on the whole recordset and export each filtered recordset to its own Excel

Writing a routine to create sequential records

阅读更多关于 Writing a routine to create sequential records

问题 I would like to write a routine which will allow me to take dated events (records) in a table which span accross a set time frame and in the cases where no event took place for a specific day, an event will be created duplicating the most recent prior record where an event DID take place. For example: If on September 4 Field 1 = X, Field 2 = Y and Field 3 = Z and then nothing took place until September 8 where Field 1 = Y, Field 2 = Z and Field 3 = X, the routine would create records in the
