Here is a chart I put together which shows all possible Visual Basic KeyAscii values along with the character which they represent. VB KeyAscii values can range from 0 to 255. To type out any of these characters without pressing the actual character you can hold down the left ALT key on your keyboard and use the number pad on the right of your keyboard to type in the corresponding ASCII value. For instance, typing ALT+66 will yield B. For numbers above 127 use "0 + the number". For instance to find the character which corresponds to KeyAscii value 134 you would type ALT+0134 which yields †. I also have a VB KeyCode chart, a VB KeyCode Constants Chart and a seperate program I've written called VB KeyAscii & KeyCode Finder that can tell you the KeyAscii and KeyCode value for any character.
