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

没有足够的信息来回答这个问题的细节。最常见的原因是：您正在尝试读取未分配的内存。



我建议你阅读：分析崩溃以查找应用中的安全漏洞 [ ^ ]。

请调试程序并检查错误。

There is not enough information to answer this question with details. The most often reason is: you're trying to read unallocated memory.

I would suggest you to read this: Analyze Crashes to Find Security Vulnerabilities in Your Apps[^].
Please, debug you program and check for errors.

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.

Bin sprintf 并删除任何数组和指针。了解如何使用 std :: stringstream 和 std :: string 。如果你还有问题，那就回来再问一遍。

Bin sprintf and get rid of any arrays and pointers. Learn how to use std::stringstream and std::string. If you've still got a problem then come back and ask again.
