[Copied code from below comment]

void CEditBox_1Dlg::OnBnClickedButton1()
{
    // TODO: Add your control notification handler code here
    CString csSamplFreq;

    char carrSamplFreq[50],csTemp[50];
    char *pcSamplFreq = NULL;
    pcSamplFreq =(char*)carrSamplFreq;

    m_CntrlDisplay.SetFocus();
    m_CntrlDisplay.GetWindowText(csSamplFreq);
    strcpy(carrSamplFreq,(LPCSTR) (CStringA)csSamplFreq);
    pcSamplFreq += usCurPos;
    sprintf(csTemp,"%s",pcSamplFreq);
    for(short sLoop = 0;sLoop<strlen((char*)csTemp);sLoop++)
    {
        *pcSamplFreq =csTemp[sLoop]; pcSamplFreq++;
    }
    *pcSamplFreq = '\0';
    csSamplFreq.Format(L"%s",carrSamplFreq);
    m_CntrlDisplay.SetWindowText(csSamplFreq);
    usCurPos++;
    m_CntrlDisplay.SetSel(usCurPos,usCurPos);
    //m_CntrlDisplay=atoi(carrSamplFreq);
    m_TxtSamplingFrequency = carrSamplFreq;
    UpdateData(false);
}

推荐答案

Quote：

strcpy（carrSamplFreq，（LPCSTR）（CStringA）csSamplFreq）;

strcpy(carrSamplFreq,(LPCSTR) (CStringA)csSamplFreq);

这不是分配（宽） CString 内容到字符数组。





This is not the correct way for assigning a (wide) CString content to character array.



引用：

pcSamplFreq + = usCurPos;

sprintf（csTemp，％s，pcSamplFreq）;

pcSamplFreq += usCurPos;
sprintf(csTemp,"%s",pcSamplFreq);

我想 usCurPos 在那里失控。





我认为在你的情况下，如果你告诉我们想要实现什么而不是坚持修复丑陋的 CString-character数组混合物，那可能会更好。

I suppose usCurPos is out-of-control there.


I think in your case it would probably better if you tell us what are trying to achieve instead of insist on fixing the ugly CString-character array mixture.
