Capturing a 'delete' key press
delphi, delphi-2009, keypress
Solution
You should handle the `OnKeyDown` instead of the `OnKeyPress` event. If you do that then `VK_DELETE` should work for you. Note that the parameter for `OnKeyDown` and `OnKeyUp` is a `Word`, not a `Char` as for `OnKeyPress`.
Problem
I can't figure out how to capture the Deletekey press. I found out that in ASCII code table, it is at 127 place, but `if (Key = #127) then` got me nowhere. Then I checked the value of `VK_DELETE` which was 47. Tried to use that, but it didn't work. The `KeyPreview := true` is set in my form. I tried to add the `ShowMessage(IntToStr(Ord(Key)))` to the Forms KeyPress event, but I never got the message popup while clicking the Delete key. I need to handle the Delete key press in dynamicaly created Edit fields. I want to control what part of the text user can erase in that field, and I know how to handle the text deletion using Backspace key, now need to figure out how to do it with Delete key. Thanks
