Question

我的应用程序在Visual Studio内部运行时工作正常，但如果我使用EXE文件运行它会崩溃。 [调试exe]

当应用程序到达这行代码时出现问题：

            nmax=2*(nrows+rows);
            create_progrcntl(L"Processing please wait"); // Crashes here
            pgr->m_pgr.SetRange32(1,nmax);
            pgr->m_pgr.SetStep(1);

create_progresscntl函数是：

 void import::create_progrcntl(CString header)
{

 pgr = new CPgr;
 pgr->Create(IDD_PROGRESS,this);
 pgr->SetWindowTextW(header);
    pgr->ShowWindow(SW_SHOW);    
}

我也将这个功能用在其他几个地方，它不会造成任何错误。它仅用于崩溃的函数import::processENSAT_MasterSlave()。

它在VS内部运行良好，但如果我在外面运行EXE则会崩溃。

我将进程附加到VS调试器。这是我的调用堆栈，就在崩溃之后：

已解决：buf初始化为buf=new char[6];。后来读入了21个字节。非常感谢@atzz
