Set all Controls TabIndex Property as in order. If the control is comboBox or dateTimePicker we can use Control Key plus Up Key to go to previous Control and use only Enter Key to go to next Control.Ĭreate a Form with some text boxes and one ComboBox and One DateTimePicker. If you want to go next control (textbox, comboBox, dateTimePicker.etc) you can press Enter Key or Down Key and if you want go to previous control you can press Up Key. In this article I am describing some tricks that are very useful in Windows Form Application Development, as this minimizes the use of mouse and maximizes the functionality of your application.

( Opening, closing AutocompCombobox for getting it working and whats the cause for the BINGS which normally signs me that an error occurs or some actions should be ended before leaving the window ? In the VB Testprogram so I can compare the functions and their events I have done a VB usual ComboBox just next Pushing the TabKey still gets a BING ( sound ) Although leaving the AutocompcomboBox by pressing EnterKey ( when programmed to do so in VB ) }Now the events are working in VB, but when I push TabKey it can be seen in KeyDown ( which is not in a normal Combobox, you only get it in KeyPress eventĪnd before I implemented OnChar it was not fired in KeyUp, Keydown event ! Void CAutoCompComboEditCore::OnChar(UINT nChar, UINT nRepCnt, UINT nFlags) M_control->m_comboIntern.SetSelectedItem() Void CAutoCompComboEditCore::OnKillFocus(CWnd* pNewWnd) M_control->KeyUp(&m_Ke圜ode,m_lastControlSign) Void CAutoCompComboEditCore::OnKeyUp(UINT nChar, UINT nRepCnt, UINT nFlags) M_control->KeyDown(&m_Ke圜ode,m_lastControlSign) ĬEdit::OnKeyDown(nChar, nRepCnt, nFlags) M_lastControlSign |= (shift = BT_ALT) ?ěS_ALT : 0 M_lastControlSign |= (shift = BT_CONTROL) ?ěS_CONTROL : 0 M_lastControlSign |= (shift = BT_SHIFT) ?ěS_SHIFT : 0 If ((shift = BT_SHIFT) || (shift = BT_CONTROL) || (shift = BT_ALT)) In the derived Class of CEdit I did as you can see hereĬode: void CAutoCompComboEditCore::OnKeyDown(UINT nChar, UINT nRepCnt, UINT nFlags) Then I created Userdefined KeyUp, KeyDown and KeyPress events. Opening and Closing the AutoCompCombobox then again pressing TabKey it is again setting Focus to next control as it should.īecause of this I was also subclassing the CEdit Box of this ComboBox in OnCtlColor() as I found out a some Microsoft Help with a selfcreated Class derived from CEdit and built new by clicking to my control with the mouse,) and again using TabKey a BING occurs Going back with Focus again to AutocompComboBox ( e.g. If Focus is in AutoCompComboBox, done nothing else and pushing Tab Key -> Focus changes to next control as ist should do. Testing the ComboBox in a Basic Testapplication, I have written only for this purrpose I had the following troubels: My problem is: Stockproperties like KeyUp, Keydown KeyPress didn't work. In Visual C++ I work with Visual using the Visual C++ 7.0 Compiler for this programming. I have tried to program an Autocomletion ComboBox which I have to use in VB 6.0 Maybe an easy problem for them who knows: I'm a newbie in programming Active X so please be patient with me.
