Let me explain. As ham radio station beacon on APRS I receive a text line 
contain a position report and sometimes weather info. I store that in a 
database, and display a button on a map indicating the position. I use a 
button because a picture can be displayed on the button. That portion is 
fine. But the buttons (location indicators) need to expire after a certain 
length of time if the location has not been updated. The expiration is where 
I have a problem. I have to have the program look through all the stations in 
the database and find the old buttons and delete them. I store the Buttons 
name and current handle in the database.

My problem is I have not figured out how to delete a button via program code.


     DO WHILE TRUE
        hButton = NEW Button(ME) AS "Station"
        hButton.X = rData!DLongitude
        hButton.Y = rData!DLatitude
        hButton.Raise
        hButton.Text = rData!Station
        hButton.Width = 75
        hButton.Height = 7
        hButton.Font.Size = 6
        hButton.Picture = Picture[rData!Icon]
        hButton.Tag = rData!Statusline
        mCount = mCount + 1



     IF rdata!station = "THORN" THEN
        textbox1.Text = hbutton.name
        i = hbutton.name
        hbutton(i).delete
     END IF



        IF mCOunt = rData.Count THEN
           BREAK
        ENDIF
        rdata.MoveNext
     LOOP
