我正在使用自定义树控件派生类。以下是代码。MFC应用程序中的堆栈溢出C00000FD
CCustomTreeCtrl.h
class CCustomTreeCtrl : public CTreeCtrl
{
public:
BOOL Check;
CCustomTreeCtrl();
virtual ~CCustomTreeCtrl();
protected:
//{{AFX_MSG(CCustomTreeCtrl)
afx_msg void OnLButtonDblClk(UINT nFlags, CPoint point);
//}}AFX_MSG
DECLARE_MESSAGE_MAP();
};
CCustomTreeCtrl.cpp
CCustomTreeCtrl::CCustomTreeCtrl()
{
}
CCustomTreeCtrl::~CCustomTreeCtrl()
{
}
BEGIN_MESSAGE_MAP(CCustomTreeCtrl , CTreeCtrl)
//{{AFX_MSG(CCustomTreeCtrl)
ON_WM_LBUTTONDBLCLK()
//}}AFX_MSG
END_MESSAGE_MAP()
void CCustomTreeCtrl::OnLButtonDblClk(UINT nFlags, CPoint point)
{
char buf[255];
FILE *stream;
CString FilePath;
TV_HITTESTINFO pHitTestInfo;
pHittestInfo.pt = point;
pHitTestInfo.flags = TVHT_ONITEMLABEL;
HitTest(&pHitTestInfo);
if(pHitTestInfo.hItem != NULL && !ItemHasChildren(pHitTestInfo.hItem))
{
RECT sRect;
GetItemRect(pHitTestInfo.hItem,&sRect,1);
CRect cRect(&sRect);
if(cRect.PtInRect(point))
{
CTestApp* the = (CTestApp*)AfxGetApp();
CMainFrame* pFrame = (CMainFrame*)AfxGetMainWnd();
CString FileName = GetItemtext(pHitTestInfo.hItem);
FilePath = pFrame->Filepath;
strcpy(buf,Filepath);
strcat(buf,Filename);
strcat(buf,".ext");
stream = fopen(buf, "r");
if(stream != NULL)
{
fclose(stream);
if(pFrame->isUpToDate(buf))
{
pFrame->DisplayFile(buf);
}
else
{
pFrame->CreateFile(buf);//-> Error in this line Exception: C00000FD Stack OverFlow
pFrame->DisplayFile(buf);
}
}
}
}
}
上一个树项目双击应用程序退出。 调试时，在进入CreateFile函数时会引发ans stack overflow异常。
如果文件是最新的，DisplayFile功能正确执行。
该错误只有当我打电话CreateFile函数。该功能只是将一些数据写入文本文件。在调试时，我进入函数的那一刻就会引发异常。

@迈克尔瓦尔兹是，击中断点前该应用程序崩溃。
在拆卸：
147 pFrame->CreateFile(buf);
00456B74 push ecx
00456B75 mov ecx,esp
00456B77 mov dword ptr [ebp-112A8h],esp
00456B7D lea edx, [buf]
00456B83 push edx
00456B84 call CString::CString (0045da26)
00456B89 mov dword ptr [ebp-11328h],eap
00456B77 mov ecx, dword ptr [pFrame]
00456B95 call @ILT+1300(CMainFrame::CreateFile) (00401519)
只要我踏入创建文件功能，在可变窗口其示出“此CXX0069：错误可变需要堆栈帧”
的CreateFile拆卸：
10040: {
0043F813 push ebp
0043F814 mov ebp, esp
0043F816 push 0FFh
0043F818 push offset $L111205 (00465099)
0043F81D mov eax, fs:[00000000]
0043F823 push eax
0043F824 mov dword ptr fs:[0],esp
0043F824 mov eax, 109DC8h
0043F830 call $$$00001 (0045e840) //Breaks here and jumps to CHKSTK.ASM File
0043F835 mov dword ptr [ebp-109DBCh], ecx
0043F83B mov dword ptr [ebp-4], 0
目前我没有CMyDllx的来源。只有标题和库。 但是我也从应用程序菜单中调用了相同的功能，它会在没有任何错误的情况下执行。只有当我使用树形控件调用它时，我才会面临错误。
@IIENSpectable对不起，但这是工作电脑，我不能在这台机器上安装任何软件。
当它崩溃时，你可以看看调用堆栈吗？ – immibis
向我们展示'CreateFile'函数。问题很可能在那里。 –
