在VC ^中更改txt文件的名称 [英] Changing a name of a txt file in VC^

问题描述

您好我有以下代码

Hi I have the following code

CString str1;
CFileDialog   FileDlg1(FALSE," ","ch1",OFN_FILEMUSTEXIST | OFN_HIDEREADONLY | OFN_OVERWRITEPROMPT , "TXT File(*.txt)|*.txt|All(*.*)|*.*|");
if(FileDlg1.DoModal()==IDOK)
{
    ofstream ofs(FileDlg1.GetPathName());
    ofs.write(str1,str1.GetLength());
    ofs.close();
    AfxMessageBox("CH1 Data Saved!");
}

ofstream Data_ch1("ch1.txt", ios::out);

简单地说，它将Data_ch1的数据保存在txt文件中。问题是它使用名称ch1.txt保存数据，如果更改此名称，则文件中将丢失数据。我需要一种方法来更改文件的名称，以便更改内的名称取决于用户。



我尝试了什么：



我试图使用GetWindowText和SetWindowText，但是它们没有用。

what it simply does, it saves the data of Data_ch1 in a txt file. the problem is that it saves the data with the name ch1.txt and if this name is changed the data will be missed in the file. i need a method to change the name of the file so the name inside " " is changed depends on the users.

What I have tried:

I tried to use GetWindowText and SetWindowText but they did not work.

推荐答案

而不是使用硬编码值ch1.txt，使用 FileDlg1.GetPathName（）。这将返回用户选择的文件的名称。

Instead of using the hard coded value "ch1.txt", use FileDlg1.GetPathName(). That returns the name of the file selected by the user.
