Goto VB Editor
In the VB Editor, click on Help>Microsoft Visual Basic Help
A dialog box pops up provided you have the VBA help files loaded with
Access.
Click on the "Contents" tab
Double Click on Topic, "Visual Basic Language Reference"
Double Click on Sub-Topic, "Miscellaneous"
There's 2 pages in there, one for ASCII codes 0 - 127 and the other for
ASCII codes 128 - 255.
Between these 2 pages, it will give you a good majority of what each of the
ASCII codes are that you are looking for. However, there are some that it
doesn't give. If you need to know those, you can go into either Excel or
Word, and then press and hold the "Alt" key while you use the "NUMPAD" and
type in the number code of the ASCII code you want with out the leading
zeroes (0s), such as "Alt-3" to bring up a picture of a heart.
