请帮忙一个简单的问题？

在SDI的窗口（此窗口继承CEditView类）中输入的信息（字母或数字），程序中怎样获得？
很急，各位高手请帮忙！

你可以用GetwindowText()这个函数式式。

在视图类中的话，直接
CString strText;
GetWindowText(&strText);//strText中的就是你要的信息

如果在其它地方的话，你也可以先得到视图的指针，然后用GetWindowText得到！

编译出错！
error C2664: 'void __thiscall CWnd::GetWindowTextA(class CString &) const' : cannot convert parameter 1 from 'class CString *' to 'class CString &'
A reference that is not to 'const' cannot be bound to a non-lvalue

[handwolf]

那就用
GetWindowText(strText);

[chenxx96]

还是取不到任何东东啊？

使用HOOK, 如下面这些代码：

LRESULT FAR PASCAL
GetMsgProc(int nCode, WPARAM wParam, LPARAM lParam)
{
LPMSG lpMsg = (LPMSG) lParam;

if ( nCode >= 0 && PM_REMOVE == wParam )
{
// Don't translate non-input events.
if ( (lpMsg->message >= WM_KEYFIRST && lpMsg->message <= WM_KEYLAST) )
{
if (::IsDialogMessage(m_hDlgWnd, lpMsg) )
{
// The value returned from this hookproc is ignored,
// and it cannot be used to tell Windows the message has been handled.
// To avoid further processing, convert the message to WM_NULL
// before returning.
lpMsg->message = WM_NULL;
lpMsg->lParam = 0;
lpMsg->wParam = 0;
}
}
}

return CallNextHookEx(m_hDlgHook, nCode, wParam, lParam);
}


然后在OnInitDialog中加下下面一行:
m_hDlgHook = SetWindowsHookEx( WH_GETMESSAGE, GetMsgProc,
NULL, GetCurrentThreadId() );
