MFC 编辑控件更新
我尝试更新编辑控件的文本,使用它添加的变量,这是一个 CString
,但我失败了.
I try to update an edit control's text, using it's added variable, which is a CString
but i'm failing it.
m_sNrAuto = "some text";
UpdateData(TRUE);
我也尝试过使用 UpdateWindow()
,但编辑控件仍为空白.我知道我可以通过使用 SetWindowText()
来做到这一点,但我也看到了一些片段,其中 SetWindowText()
没有使用,更新是通过将值传递给附属的 CString.
I also tried using UpdateWindow()
, but the edit control remains blank. I know i can do it by using SetWindowText()
, but i also saw some snippets where SetWindowText()
it's not used, the update is done by passing a value to an affiliated CString.
推荐答案
试试 UpdateData(false);
true
表示 Control=>数据
true
means Control=>Data
false
表示数据=>控制
有时你必须这样做
UpdateData(true); // snapshot ALL controls data
m_sNrAuto = "some text"; // tweak the one you actually need updated
UpdateData(false); // this pushes ALL data, not just the one you tweaked
