如何获取在编辑框中输入的数据? [英] How to get the data entered in an edit box?

问题描述

CString lpstring;
    m_cedit.GetWindowText(lpstring.GetBuffer(),20);
	EndDialog(IDD_EDITBOX_DIALOG);
    lpstring.ReleaseBuffer();

我已经在OnOk() 函数中尝试过此操作，因为我想将此值保存在数据库中.但是我在运行程序时遇到一些错误，例如调试断言错误.

I have tried this in the OnOk() function because I want to save this value in the database. But I am getting some error while I am running the program like Debug assertion error.

推荐答案

您应该在对话框中使用类变量和CDialog类的DoDataExchange方法中的DDX宏.请参见此处 [

You should use the class variables in your dialog and the DDX macros in the DoDataExchange method of your CDialog class. See here[^] for further information.
