    Cool CFileDialog Compile Error. thanks.

    HI

    Good day.

    I plan to creat a small tool which for convert Ascii file to UTF-8 file.
    I already find the piece of convert code.(in C++)

    Now i plan to build the simple form.
    When i click the "Select Source File" button, I want to select the source(ASCII) file.

    I add the below button1_click function at Form1.h file, but it compiled fialed.

    Code:
    	private: System::Void button1_Click(System::Object^  sender, System::EventArgs^  e) {
    
    		   // Create an Open dialog; the default file name extension is ".my".
    
    		   CFileDialog fileDlg (TRUE, _T("my"), _T("*.my"),
    
    			  OFN_FILEMUSTEXIST| OFN_HIDEREADONLY, _T("MyType Files (*.my)|*.my|All Files (*.*)|*.*||"), this);
    
    
         		   // Display the file dialog. When user clicks OK, fileDlg.DoModal() 
    		   // returns IDOK.
    		   if( fileDlg.DoModal ()==IDOK )
    		   {
    
        		           CString pathName = fileDlg.GetPathName();
    
    			  // Implement opening and reading file in here.
    
    			  //Change the window's title to the opened file's title.
    
    			  CString fileName = fileDlg.GetFileTitle ();
    
    			  //SetWindowText(fileName);
    		   }
    		}
    Compiled Output

    MFC and Windows Form do not work together.
    Switch to native C++ or use the file dialog of C++/CLI.
