Visual C ++从Cedit获取字符串 [英] Visual C++ get string from Cedit

问题描述

这可能是一个非常基本的问题，但我似乎无法理解.我在一个visualC ++项目上工作，我基本上想从GUI中获取一个字符串，然后将其用作文件名.到目前为止，我已经写了以下内容，其中IDC_FILE_NAME是编辑控制框的ID，但是我不确定这是否是实现此目的的方法.

This is probably a pretty basic question, but I can't seem to get it. I am working on a visualC++ project and I basically want to get a string from a GUI and then use that as a filename. I have written the following thus far, where IDC_FILE_NAME is the ID of the edit control box but I'm not sure if that is even the way to accomplish this.

m_pFileName = (CEdit*)GetDlgItem( IDC_FILE_NAME );

CString fName =_T(" ");
GetDlgItemTextA(IDC_FILE_NAME, fName);

答案是是和否. 是，如果使用得当， 不，不是像您那样做. 除非要强制使用UNICODE或ANSI，否则不要使用UNICLODE/ANSI特定版本的函数. 您的代码应如下所示:

The answer is YES and NO. YES if properly used, NO, not as you do it. Do not use UNICLODE/ANSI specific versions of functions unless you want to force UNICODE or ANSI. Your code should look like:

    CString csText;
    GetDlgItemText(IDC_FILE_NAME, csText);

注意 GetDlgItemText
