ABC: Set a value in a browse without a form or Edit in Place
2004-02-04 -- Arnor Baldvinsson
 
A friend of mine asked me how he could update a single field in a browse without calling the form or use Edit in Place. The field in question was a simple byte field which was shown in the browse with a checkbox icon, on or off depending on the value of the field. This is the code I came up with and it seems to work just fine. Put this code into the BrowseClass ASK method, before the parent call: 
   If ?Browse:1{PROPLIST:MouseDownField} = 1 ! First column only
     BRW1.UpdateBuffer
     CUS:isrecordtagged = Choose(CUS:isrecordtagged=False,True,False)
     If Access:Customers.Update() = LEVEL:Benign
       BRW1.ResetFromFile
       RETURN(LEVEL:Benign)
     End
     RETURN(LEVEL:Notify)
   End

This will make double clicks on the first column toggle the CUS:isrecordtagged and then it updates with the correct checkbox icon automatically. The record is then updated and the browse refreshed from the file and the method returns. Double clicking on any other column will call the form.

If you want this on a window without update buttons, you need to manually call the ASK method. Add the following code to the TakeKey method of the Browse object: 

 If KeyCode() = MouseLeft2
   ThisWindow.Update            ! This will locate the browse on the current record
   SELF.ASK(ChangeRecord)       ! Call the ASK method with ChangeRecord
 End
That's it!

Fix to a problem with double clicking

Reported by Kelly E Major:

I created a quick test program and this code works, but it has a problem.  If
you try to use one of the update buttons after double clicking to change a field
it will change the field of the active record in the list instead of calling the
form.  I added this line of code right after the first if...

?Browse:1{PROPLIST:MouseDownField} = 0

and it seemed to resolve that problem but I have not tested extensively.  Now I
just need to get it working with a single click and my clients will be happy.
