Solution to the problem that OCX controls do not receive direction keys and other keyboard messages in the modeless dialog box of IE

If the OCX control contains a non-modal dialog box, when OCX is displayed in IE, it often does not receive tabs, direction keys, and backspace keys. All these messages are intercepted by the IE container. For this problem, Ms provides a solution: first: Int cmyactivexctrl: oncreate (maid)
{
If (colecontrol: oncreate (lpcreatestruct) =-1)
Return-1;
Onactivateinplace (true, null); // = UI-activate the control
Return 0;
}
Activate the control to receive keyboard messages.Second, tracking and forwarding messages // Trap keys and forward on to the control
Bool cmyactivexctrl: pretranslatemessage (MSG * PMSG)
{
Switch (PMSG-> message)
{
Case wm_keydown:
Case wm_keyup:
Switch (PMSG-> wparam)
{
Case vk_up:
Case vk_down:
Case vk_left:
Case vk_right:
Case vk_home:
Case vk_end: Case vk_tab:
: Sendmessage (PMSG-> hwnd, PMSG-> message, PMSG-> wparam, PMSG-> lparam );
// Windowless controls won't be able to call sendmessage.
// Instead, just respond to the message here.
Return true;
}
Break;
}
Return colecontrol: pretranslatemessage (PMSG );
}Note that use send instead of post. Other References: http://support.microsoft.com/kb/q168777/http://www.microsoft.com/msj/0795/dilascia/dilascia.aspx
