I need to prevent a user from entering in any TEXTBOX on the FORM either of these characters: ^ ~
I know I can trap them in the EN_CHANGE for each Textbox but was hoping I could trap them in the FF_PUMPHOOK Function. There doesn't appear to be a %VK_ for those characters probably because the require the shift key to type them.
Any suggestions how I can trap them and not allow them to type into any Textbox on the form. ???
Haven't tested, but in inc file:
%VK_OEM_3 = &HC0 ' "`~" for US
The other would probably need to check for 6 key with Shift. May be easier to wait and get the Char instead of Keypresses using WM_CHAR.
If you use FF's built in WM_CHAR for the textbox the chCharCode will be the ascii of the char. Something like below will block the 'a' key:
If chCharCode = 97 Then Function = 1
You will need to handle when they paste too or block it.
Textbox custom:
If wMsg = %WM_PASTE Then Function = 1
Thanks Roger. I will play with those suggestions tonight. And if I can make them work.
It looks like the shift key is &H10 and the tilde is &H7E and ^ is &H5E. These are all for keypress. The keyUp code changes for the 2 keys (&HC0 and &H36 respectively).
Maybe this will get you started.
