solution:
First, declare the external function:
Subroutine KeyBD_EVENT (int BVK, Int Bscan, Ulong Dwflags, Ulong Dwextrainfo) library "user32.dll"
First, if you don't want to use the left and right keys to edit content in DW, you can switch to other cells as long as one button is pressed.
New UE_KEY corresponds to PBM_DWNKEY, the code is as follows:
IF key = keyftarrow! then
KeyBD_Event (16, 0, 0) // Press the Shift button
KeyBD_Event (9, 0, 0) // Press Tab
KeyBD_Event (9, 0, 2, 0) // Release the Tab button
KeyBD_EVENT (16, 0, 2, 0) // Unnumped SHIFT
Return 1
Elseif key = keyrightarrow! Then
KeyBD_Event (9, 0, 0) // Press Tab
KeyBD_Event (9, 0, 2, 0) // Release the Tab button
Return 1
END IF
Second, if you want to use the left and right keys to edit content in the cell of DW, you can only switch to other cells when you empty or completely elect, you can:
New UE_KEY corresponds to PBM_DWNKEY, the code is as follows:
Integer li_len, li_len_selected
li_len = len (this.getText ())
li_len_selected = le (this.selectedText ())
IF not (isnull (this.gettext ()) or this.gettext () = "" or li_len = li_len_selected) THEN RTURN
IF key = keyftarrow! then
KeyBD_Event (16, 0, 0) // Press the Shift button
KeyBD_Event (9, 0, 0) // Press Tab
KeyBD_Event (9, 0, 2, 0) // Release the Tab button
KeyBD_EVENT (16, 0, 2, 0) // Unnumped SHIFT
Return 1
Elseif key = keyrightarrow! Then
KeyBD_Event (9, 0, 0) // Press Tab
KeyBD_Event (9, 0, 2, 0) // Release the Tab button
Return 1
END IF
