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. CString temp2; //Since the stuff in the textbox is a CString. m_scanPath.GetWindowText(temp2); //Get the directory entered in the textbox. const char * tempString = temp2.GetBuffer(); //Convert it to a const char *. fs::path scanPath(tempString); //This does not work even though the param is a const char *) What am I doing wrong? I imagine it is some type of type casting problem? Thanks in Advance, Ryan --------------------------------- Do you Yahoo!? Express yourself with Y! Messenger! Free. Download now.
What is the value of tempString that is causing the problem? On Sep 8, 2004, at 9:30 PM, RYAN ROSARIO wrote:

Unfortunately the VS debugger is not showing a value for tempString (it is not listed). temp2 looks ok though.
