Getline错误MFC vs2012(msvcp110.dll) [英] Getline error MFC vs2012 (msvcp110.dll)
问题描述
我有一个问题,使用stvs :: getline函数在vs2012与MFC应用程序。同样的代码在vs2010中运行,这就是为什么我确定它不是代码本身的问题。
void AddImage :: OnClickedIdbAiRegistration(){
CFileDialog file(TRUE,NULL,NULL,OFN_OVERWRITEPROMPT,(* .dat)| * .dat ||
file.DoModal();
UpdateData();
m_ai_file = file.GetPathName();
UpdateData(FALSE);
std :: string buf = m_ai_file;
if(filecnt(buf,Dat)){
std :: ifstream file(buf);
AfxMessageBox(buf.c_str());
std :: getline(file,buf); //这是我的问题
AfxMessageBox(buf.c_str());
file.close();
}
}
第一个AfxMessageBox返回文件路径有效的ASCII文件)。第二个AfxMessageBox从未到达,因为getline产生:
程序中的0x000007FEF7B4AAEE(msvcp110.dll)未处理的异常:0xC0000005:Access违反阅读位置0xFFFFFFFFFFFFFFFF。
和vs11将我重定向到xiosbase行443
< pre =lang-cpp prettyprint-override>
locale __CLR_OR_THIS_CALL getloc()const
{// get locale
return(* _Ploc); / * THIS IS LINE 443 * /
}
对于项目属性,我使用在共享dll中使用MFC和多线程DLL和子系统Windows

错误?
我现在使用VS10解决了这个问题。有算法工作没有任何问题。但是我不认为这可以是解决方案!
它在同一台电脑上与vs10工作告诉我,这不是一个问题与电脑。 / p>
I have a problem to use the std::getline function in vs2012 with an MFC application. The same code was running in vs2010 that's why I am sure that it is not a problem with the code itself.
void AddImage::OnClickedIdbAiRegistration(){
CFileDialog file(TRUE, NULL, NULL, OFN_OVERWRITEPROMPT, "(*.dat)|*.dat||");
file.DoModal();
UpdateData();
m_ai_file=file.GetPathName();
UpdateData(FALSE);
std::string buf=m_ai_file;
if(filecnt(buf, "Dat")){
std::ifstream file(buf);
AfxMessageBox(buf.c_str());
std::getline(file, buf);//Here is my problem
AfxMessageBox(buf.c_str());
file.close();
}
}
The first AfxMessageBox returns the filepath (which is correct and a valid ASCII-file). The Second AfxMessageBox do i never reach because getline produces:
Unhandled exception at 0x000007FEF7B4AAEE (msvcp110.dll) in program.exe: 0xC0000005: Access violation reading location 0xFFFFFFFFFFFFFFFF.
and vs11 redirect me to the xiosbase line 443
locale __CLR_OR_THIS_CALL getloc() const
{ // get locale
return (*_Ploc);/*THIS IS LINE 443*/
}
For the project property i am using "Use MFC in a shared dll" and "Multi-threaded DLL" and Sub-System "Windows"

Anyone an idea what is going wrong?
I have solved the problem now by using VS10. There the algorithm works without any issues. But I do not think that this can be the solution!
That it works with vs10 on the same PC tells me also that it is not a problem with the PC.
