I assume that you have only one active field of one character on your form. You can't use When-Validate-Item trigger on this field to perform a Close-Form unless you use a 'timer'.

I don't understand how you can use 'L' for LOV as you can't tell the difference between a data 'L' and control 'L'. The only time I have seen asci characters used for control is on a control only or flash screen.

Thanx david for the Answer at least
The situation is that

i want that whenever user press
suppose S

The Form of Student record should open ..

Can i do this
like i have a main form which contain menu baar

which has differnt links to different forms. .like students, teacher , books etc ..

Can i use shortcut key to navigate in forms. .llike if i press S
the student form should be viewed..

if i press suppose T .. teacher form should be viewd..
is this possible..

This is possible in Visual Basic to use or pick up Key ascii values and work accordingly..

suppose if C has ascii value of suppose 67..

we can catpture this value on key press event in Vb and work accordking

suppose if Key ascii = 67 then
for exapmple open form ( child)

suppose ..this was just an exampe..

hope to see some good replies

thanx alot
best regards

In the menu you can specify 'hot keys' basically "alt+x" where 'x' is an asci character. You can use it the same way as you use any windows menu. The character specified will have an underscored displayed when the menu drops-down. Oracle treats upper and lower case equally when selecting the alt+key but only underscores the cahracter in the drop-down if the case in the displayed name is the same as the hot-key definition.

Normally this facility is only used for navigating between forms, leave the LOV stuff to a button on the icon bar.
