See if This Works:
1. Create a Text File Containing all Abr & Explanations
DEPT ; Department
CLS ; Clear Screen
. ; .
Blah ; Blah
Then Read the pairs into an Array
Dim prs()
Open sFile For Input As #99
cnt = 0
While Not EOF(99)
cnt = cnt + 1
Line Input #99, myLine
LineArray = split(myLine,";")
redim Preserve prs(2,cnt)
prs(0,cnt) = lineArray(0)
prs(1,cnt) = lineArray(1)
Wend
Close #1
now you can populate the combobox from prs(0,n)
for xx = 1 to cnt
me.ComboBox1.AddItem prs(0,xx)
next
finally you can display the definition of the selected abr.
. . . inside click event
for xx = 1 to ubound(prs,2)
if me.ComboBox1.Text = prs(0,xx) then
msgbox prs(0,xx) & " = " & prs(1,xx)
end if
next
Hope this helps
