问题描述
Hi;
I have an edit control that takes string input from user and a CButton 'Record' to record that input. I want to catch the control and disable it when the user input is empty. I want to make sure that this enable/diable happens with the click of CButton.
void CCTRL::OnBnClicked() // code for Cbutton
{
CString txt;
if(!end)
{
IsCorrect(s); // comparing and checking user input
m_input.SetCheck(0);
if(Check())
Run();
}
}
IsCorrect() is where user input is checked and compared with correct text.
编辑控件是受时间驱动的，需要先禁用一段时间，然后用户才能再次单击它.
在显示控件之前，一旦某些文本输入到编辑控件中，cbutton可能会被禁用并变为启用状态.
等待建议.
预先感谢.
The edit control is time driven and need to be disabled for a certain time before user can again click it.
Could it be possible that before display of control, cbutton is disabled and becomes enable once some text is input into edit control.
Waiting for suggestions.
Thanks in advance.
