(IMG:style_emoticons/default/compute.gif) Access Tips: Query and Filter Criteria. When constructing a query or a filter, you need to tell Access what to look for in each field.
You do this by defining criteria - typing something (an "expression") into the Criteria cell of the query or filter grid. If you do not define any criteria for a particular field, Access assumes that you are applying no constraints and will display everything it has. This means that you only have to define criteria for those fields you are interested in. Here are some examples of the more common types of criteria. Often Access will complete the expression so that you need only type the text you want to match. The list of examples below is not exhaustive. This tutorial is arranged in the following sections: Matching Text. Microsoft Access. Help using Access visual basic modules and documenting your database. Export an Access query as an HTML Web Page. Sub MakeHTMvacancies() '* Create an HTML page displaying the query: Vacancies Dim MyDB As Database, MySet As Recordset Dim MyFileName As String, MyCurrentGroup As Stringe ' declare variables for running totals of numeric fields Dim Var As Single, Bud As Single, Wkd As Single, Con As Single, Vac As Single DoCmd.Hourglass True Set MyDB = CurrentDb() Set MySet = MyDB.OpenRecordset("vacancies", dbOpenDynaset) MyFileName = "R:\vacancies.htm" Open MyFileName For Output As #1 MySet.MoveFirst MyCurrentGroup = "x" ' on each change of the field MySet!

Prompt For Saving a Record with VBA. Prompt For Saving a Record Microsoft Access automatically saves any changes we make to a record, whether we close the form or move to a new record.
I will show you a way of prompting a user to save the changes. Here is my form before I make any changes to the record. Now I add the word ‘Test’ into the ‘Last Name’ field. I then move to the next record and get the message informing me that the record has changed and do I want to save it. If I answer ‘Yes’ the changes will be saved. If I answer ‘No’ my changes will not be saved. In order to do this I added a bit of VBA code. Go into form design and bring up the form properties. Click on the top part of the form: Go up to the ‘View’ menu and select ‘Properties’: We want to look at the event properties, specifically the ‘Before Update’ event: Click the small button with the dots, the ellipsis (...), to bring up the code window:
