Okay so I am writing a fairly simple dialog based MFC Windows Application and have run into an issue. My dialog contains a few buttons and a list box. When the user clicks one of the buttons, Generate, a text file is opened and its contents are displayed in the list box (m_ctlListBox) line by line. As is, the program builds fine but when the Generate button is pressed the list box seems to disappear and then the app crashes. Any help would be really appreciated!
void CMFCApp_noDLLDlg::OnBnClickedGeneratelist()
{
std::string line;
std::ifstream inFile;
inFile.open("C:/Users/.../SampleText.txt", std::ios::in);
while (!inFile.eof())
{
inFile >> std::ws;
getline(inFile, line);
CString cs(line.c_str());
m_ctlListBox.AddString(cs);
}
inFile.close();
}
