Setting Fonts on Edit Box Control

• Create a CFont global variable.

  CFont font;

• Then use method CreatePointFont() to create a font. The size of the font is measured in one tenths.

  font.CreatePointFont(100,"Courier New");

• Then get the Edit Box Control variable and set the font using the SetFont() function.

  editBoxControl.SetFont(&font);

Preventing Dialog Box from closing when ESC or ENTER is pressed

• Overload the OnOK() and OnCancel() functions in your dialog class.

      class CInventoryStoreDlg : public CDialog
      {
          // Construction
  	public:
  	CInventoryStoreDlg(CWnd* pParent = NULL);	// standard constructor
  	void OnOK() {}
  	void OnCancel() {}
          ...
          ...
      };

• But now you have to provide your own way to close the dialog.

  void CInventoryStoreDlg::OnSysCommand(UINT nID, LPARAM lParam)
  {
  	if ((nID & 0xFFF0) == IDM_ABOUTBOX)
  	{
  		CAboutDlg dlgAbout;
  		dlgAbout.DoModal();
  	}
  	if ((nID & 0xFFF0) == SC_CLOSE)
  	{
  		exit(1); // or another method to close dialog.
  	}
  	else
  	{
  		CDialog::OnSysCommand(nID, lParam);
  	}
  }

Type Converstions

• Converting a char * to int.

  // function to convert char * to int
  int returnInt( char i[] )
  {
  	int integer;
  	integer = atoi(i);  // must include cstdlib (stdlib.h) 
  	return integer;
  }

• Converting a char * to double.

  // function to convert char * to double
  double returnDouble(char i[])
  {
  	double floaty;
  	floaty = atof(i);  // must include cstdlib (stdlib.h) 
  	return floaty;
  }

• Converting a int to CString.

  // function to convert int to CString
  CString returnCString( int i )
  {
  	CString s;
  	s.Format( ("%-15d"), i );
  	return s;
  }

• Converting a double to CString.

  // function to convert double to CString
  CString returnCString( double i )
  {
  	CString s;
  	s.Format( ("%-14.2f"), i );
  	return s;
  }
