[Qt-interest] Segmentation fault while converting from QString to char*

[prashant bhutani]

Hi,
sorry for previous one.
On using statement, *char *cstr = qstr.toStdString.c_str();*
i got *‘qt_file_name.QString::toStdString’ does not have class type*

while on using char *cstr = qstr.toStdString();
i got *cannot convert std::string to char **

Regards,
Prashant
