 |
|
hi dear builders,
I need a little function that displays all ascii-codes as TButton (caption)
in a 2nd form,
OnEvent Click they should insert the ascii code in the 1st form's TEdit
box...
How can I do that ? Isn't there a possibility to create TButton dynamicly
via Cast < > (I forgot the syntax...) where each TButton representing a
ascii-code ??
something like this should work for diplaying the ascii codes:
char x;
for (int i = 0; i < 255; i++)
{
// char = i // ??? wrong...
}
Have someone a idea for me..?
Oren

Dynamically? Why??? If you want a form with 256 buttons then
build it thus. There is nothing dynamically about it!

Think that should be:
Edit1->SelText = (char)B->Tag;
or
Form2->Edit1->SelText = (char)B->Tag;
moreover you forgot to assign the eventhandler, add:
aBtn[ Index ] = GenericButtonClick;
Well Oren, could you please tell us how this all works ?
Hans.
