What is the value of tempString that is causing the problem?

<excerpt>My MFC has a text box that stores the result from a "choose
directory" dialog box. I encounter problems when I try to create a
path object from the value of this textbox. The debugger shows the
value of scanPath (what I call my path object) to be "" which is then
causing hangs and exceptions...

 

Below is the code I am trying to use. I do not see why the constructor
will not recognize the parameter I am passing to it:

//m_scanPath is a control variable for the textbox containing the
directory.


<smaller>CString temp2;    //Since the stuff in the textbox is a
CString.</smaller>


<smaller>m_scanPath.GetWindowText(temp2);       //Get the directory
entered in the textbox.</smaller>

<color><param>0000,0000,FFFF</param>char</color> * tempString =
temp2.GetBuffer();     //Convert it to a const char *.</smaller>



<smaller>fs::path scanPath(tempString);            //This does not
work even though the param is a const char *)</smaller>


<smaller>What am I doing wrong? I imagine it is some type of type
casting problem?</smaller>
