1. Based on the dialog box dlgA, put hooks in its called Installhook OnInit
2 open notepad, input
3. Press F4 tuning up a modal dialog g_pDlg, g_pDlg have an edit box m_editCode
The steps above normal
4. Adjustable g_pDlg later, looking at the cursor on the m_editCode box, but the data content is displayed in the open notepad before

Now the problem is to input content on m_editCode,
Trying several set focus ways can set the input to the m_editCode,
Trouble great god give directions, thank you

CodePudding user response:

Try sending a message set the focus changes to the API
SetFocus (g_pDlg - & gt; M_editCode. GetSafeHwnd ());

CodePudding user response:

If (( wParam==WM_CHAR ) & amp; & (HC_ACTION==nCode))

WM_CHAR is the result of the Up and Down

CodePudding user response:

Cursor blink, focus should be false
