outlook form how to change the textbox value before and after a long p

[AnNguyen]

Hello All

How can i change the textbox value before and after a long process routine? here is my code and the Textbox is preset to blank

Sub cmdShow_ click()
DescriptionMsg.Value = "Scanning in progress... "

showMessages 'long process atleast half a minute

DescriptionMsg.Value = "Scanning finished... "

end sub

The first textbox value never shown up unless there i put a msgBox after it (which is inconvenient).

Is there any way to achieve this without the msgbox statement? and if so how?

Thank you
