How to get left click notification on an edit control? - c++

Question

I want to track event of single left-click on edit control.
I override PretranslateMessage function as below:
BOOL CMyClass::PreTranslateMessage(Msg* pMsg)
{
switch(pMsg->message)
case WM_LBUTTONDOWN:
{
CWnd* pWnd = GetFocus();
if (pWnd->GetDlgCtrlID == MY_EDIT_CTRL_ID)
{
//Do some thing
}
break;
}
}
The problem is that when I click on the edit control, all other control become disabled (for example buttons don't respond to clicks etc.)
How can I fix this problem? Or how can I track click notificationN on edit box?

You need this:
BOOL CMyClass::PreTranslateMessage(MSG* pMsg)
{
switch(pMsg->message)
{
case WM_LBUTTONDOWN:
{
CWnd* pWnd = GetFocus();
if (pWnd->GetDlgCtrlID() == MY_EDIT_CTRL_ID) // << typo corrected here
{
//Do some thing
}
break;
}
}
return __super::PreTranslateMessage(pMsg); //<< added
}
BTW its a bit awkword to use a switch statement here. Following code is cleaner IMO, unless you want to add morecases than only WM_LBUTTONDOWN:
BOOL CMyClass::PreTranslateMessage(MSG* pMsg)
{
if (pMsg->message == WM_LBUTTONDOWN)
{
CWnd* pWnd = GetFocus();
if (pWnd->GetDlgCtrlID() == MY_EDIT_CTRL_ID)
{
//Do some thing
}
}
return __super::PreTranslateMessage(pMsg); //<< added
}
