You might be in all probability writing extra Microsoft Entry programming code then that you must. This implies wasted coding time, extra code upkeep and potential debugging. This text applies to all variations of Microsoft Entry, not simply Entry 2007, however many new options of Entry 2007 help you do zero coding to do duties reminiscent of bulk emails, type management resizing, scheduling duties, date choosing, formatting, and so on.
I’ve reviewed tens of hundreds of strains of programmers’ code, not simply in Entry 2007, and have discovered that many strains of code are being written in areas the place a lot much less code was wanted to do the identical job. Here is the method that can save a lot time.
Do you know that your knowledge tables in Microsoft Entry 2007 can be utilized to regulate your Entry 2007 program and write code for you, in the event that they include metadata.
Metadata is knowledge about knowledge. You’ve truly been storing and utilizing metadata because you began utilizing Entry 2007. If you select a colour for a type textbox label, you might be instructing Entry 2007 to recollect this colour and run program code that creates that colour every time that label is proven.
Okay, right here is an instance of how you might save your self from writing many strains of code through the use of metadata that you’ve got saved in an Entry 2007 knowledge desk.
Here is an instance of utilizing metadata. You’ve some stories to be printed each Tuesday and a few that must be printed each Friday. You could possibly write some Entry 2007 code to print the Tuesday stories by writing:
If Weekday(Date) = 3 then ‘It is Tuesday
DoCmd.OpenReport “Tuesday Report A”
DoCmd.OpenReport “Tuesday Report B”
DoCmd.OpenReport “Tuesday Report C”
DoCmd.OpenReport “Tuesday Report D”
DoCmd.OpenReport “Tuesday Report E”
Finish if
You’d then write some extra code for Friday stories:
If Weekday(Date) = 6 then ‘It is Friday
DoCmd.OpenReport “Tuesday Report A”
DoCmd.OpenReport “Tuesday Report B”
DoCmd.OpenReport “Tuesday Report C”
DoCmd.OpenReport “Tuesday Report D”
DoCmd.OpenReport “Tuesday Report E”
Finish if
Now let’s write these 14 strains of code with one line 7 strains of code.
Dim rs As DAO.Recordset
Set rs = CurrentDb.OpenRecordset(“Desk Identify Containing Metadata”)
Do Till rs.EOF
If ![DayOfWeek] = Weekday(Date) Then
DoCmd.OpenReport ![ReportName]
Finish If
rs.MoveNext
Loop
These 7 strains of code wouldn’t must be modified or added to even when the ten stories improve to 50 stories in Entry 2007 or every other model of Entry.
The Entry 2007 knowledge desk would solely must retailer the report identify and the day of week, simply two fields of information. This implies straightforward upkeep and no future code adjustments.
This method can be utilized for operating a set of queries with a specified sequence. Use metadata when linking to exterior knowledge sources by together with paths, file or desk names, and specs. You possibly can automate importing or exporting knowledge by storing import and export specs, codecs, and storage paths.
Need extra examples of this time saving strategy? Let me know. Suggestions is all the time appreciated.
