问题描述

调用此函数将垃圾字符显示为UNICODE类型项目中的最后一项

Calling this function showing junk charecter as last item in an UNICODE type project

//Member Function to Read Data From File And Store it in List Control
void CDataFunction::WriteFunction(CListCtrl* pListCtrl,CString* m_pFileName)
{
    m_VFlag=TRUE;
    m_VNumlist=1;
    m_VFileName = (m_pFileName->GetString());
    //Clear All Data In List Control
    pListCtrl->DeleteAllItems();
    WCHAR m_VStrBuf[256],m_VTemp[100];
    //Read All The Data in File and Store in a Buffer
    GetPrivateProfileString(_T("List1"),NULL,NULL,m_VStrBuf,256,m_VFileName);
    //Insert the Read Data into The List Control
    for(int i=0;i<=256;i++)
    {
        if(m_VStrBuf[i]!='\0')
        {
            m_VFlag=TRUE;
            for(int j=0;m_VFlag==TRUE;j++)
            {
                m_VTemp[j]=m_VStrBuf[i+j];
                if(m_VStrBuf[i+j]=='\0')
                {
                    m_VTemp[j+1] ='\0';
                    pListCtrl->InsertItem(m_VNumlist,m_VTemp);
                    m_VNumlist++;
                    m_VFlag=FALSE;
                    i=i+j;
                }
            }
        }
    }
}

推荐答案

GetPrivateProfileString()函数返回缓冲区中存储的字符数，您已将其忽略.捕获该值并将其用作字符串限制，而不是假设您将收到以null结尾的字符串.

The GetPrivateProfileString() function returns the number of characters stored in the buffer, which you have ignored. Capture that value and use it as the string limit rather than assuming that you will receive a null terminated string.

尝试替换

for(int i=0;i<=256;i++)

与

with

for(int i=0;i<256;i++)

-----编辑-----

您的评论暗示您实际上想要从垃圾中区分出返回的值.然后，您应考虑此函数的返回值，如其所述规范 [ ^ ].它还可以告诉您何时提供的缓冲区太小(因此256个字节不足)

----- EDIT -----

Your comment implies that you actually want to distinct returned values from junk. Then you should consider this function return value, as described it its specification[^]. It can also tell you when buffer provided is too small (so 256 bytes are not enough)
