MORE INFORMATION

Steps to Reproduce Behavior

The following sample program demonstrates the behavior.

*-- Begin Program
*-- Create an array from which to load records in a table.
LOCAL ARRAY aBunchONums[3,1]
*-- Create a table
CREATE TABLE testtube FREE (number n(14,4))
*-- Load three records in the table with random numbers.
=RAND(-1)
FOR i = 1 to 3
     aBunchONums[i] = RAND()*SECONDS()*VAL(sys(11, date()))/100
ENDFOR
APPEND FROM ARRAY aBunchONums
GO TOP
*-- Instantiate a form based on custom form class, TestForm.
frmMyForm = CREATEOBJECT("TestForm")
*-- Add a text box to the form with format and picture clause.
     frmMyForm.addobject("txbFooBox", "TEXTBOX")
          WITH frmMyForm.txbFooBox
               .ControlSource = "testtube.number"
               .Format        = "KZ^"
               .InputMask     = "999999999.9999"
               .Top           = 5
               .Left          = 15
               .Visible       = .T.
               .Width         = 100  && <== change this value
          ENDWITH
*-- Display the form.
frmMyForm.show

READ EVENTS

*-- Define a custom class based on the FORM baseclass.
DEFINE CLASS TestForm AS FORM
     CAPTION     = "SciNot Test"
     AUTOCENTER  = .T.
     HEIGHT      = 120
     WIDTH       = 140
*-- Add command button to move between records.
     ADD OBJECT cmdNext AS COMMANDBUTTON ;
          WITH ;
          TOP            = 50, ;
          LEFT           = 20, ;
          HEIGHT         = 24, ;
          CAPTION        = "Next"
*-- Add command button to exit the program (form).
     ADD OBJECT cmdQuit AS COMMANDBUTTON ;
          WITH ;
          TOP            = 80, ;
          LEFT           = 20, ;
          HEIGHT         = 24, ;
          CAPTION        = "Quit"
*-- Add custom code to the Click event of cmdNext.
     PROCEDURE cmdNext.click
          SKIP
          IF EOF()
               GO TOP
          ENDIF
          THISFORM.REFRESH
     ENDPROC
*-- Add custom code to the Click event of cmdQuit.
     PROCEDURE cmdQuit.click
          THISFORM.Release
          CLEAR EVENTS
     ENDPROC

ENDDEFINE
*-- End custom class definition.
*-- End program.
				

Run this program. Press the TAB key until the text box has focus. Note the displayed value changes when you move into the text box.

With the contents of the text box selected, press the HOME key on your keyboard. Now, you can see the leading characters of the scientific notation expression in the text box.

Edit the program. Go to the line that contains the comment, "<== change this value." Change the line of code to read:

     .Width         = 120
				

Run the changed program. Press the TAB key until the text box has the focus. Now the displayed value does not change when you move into the text box.
