Read file data into a class
How can I read the data from a file straight into a MFC class using visual c++ 6.0? I know that you can do it using a structure but is there a way to do it using a class?
I tried using infile.read((char*) classname, classname.GetLength());
I tried using infile.read((char*) classname, classname.GetLength());

If classname is a CString, you can use CStdioFile::ReadString to read it into the CString.
Example:
CStdioFile MyFile("data.txt");
CString MyCStr;
MyFile.ReadString(MyCStr);
Example:
CStdioFile MyFile("data.txt");
CString MyCStr;
MyFile.ReadString(MyCStr);

It is also possible to just dump a blob of data into the area where the object keeps its data members (much as it sounds like you might be doing with a struct). But it is never recommended because of the danger of overwriting important areas of memory.
