Introduction

Last week I saw a Windows 2000 server user's management.  I have seen in the session planning a control. I think that this control is very important for applications which use planning tasks. And the best use of this control is in Internet/Network applications. This article demonstrate using of window messages to create controls. This article uses WM_LBUTTONUP, WM_LBUTTONDOWN, WM_MOUSEMOVE. And demonstrate how to have a good method of drawing by repainting only the area which is modified. This is my first article for Code Project.

Usage

Simply include the header file.

#include "WeekHours.h"

Then you insert in the dialog a static control and enable the notify property (window styles). And modify the control ID, for e.g. IDC_SESSIONS_PLANNING (if you don't modify the IDC_STATIC, class wizard won't let you create variable). Then create a variable for this control (the type will be CStatic) change the type to CWeekHours .

//{{AFX_DATA(CTimeTestDlg)
enum { IDD = IDD_TIMETEST_DIALOG };
CWeekHours m_WeekHours;
...
...
...
//}}AFX_DATA

To initialize the control

The initialization of the control will be in OnInitDialog or constructor of the dialog. The set state order is important.

	
BOOL CTimeTestDlg::OnInitDialog()
{
    CDialog::OnInitDialog();

    ...
    ...
    ...

    // TODO: Add extra initialization here

    // select a language for the week days
    m_WeekHours.m_Language = LNG_ENGLISH;       

    // Selection button text
    m_WeekHours.m_SelBtnText = "Autorised connection";  
    
    // Deselection button text
    m_WeekHours.m_DeSelBtnText = "Refused connection";  


    // Select the 8 hour in all week days
    m_WeekHours.SetHourDaysState(8, HST_SELECTED);  

    // Select the 9 hour in all week days
    m_WeekHours.SetHourDaysState(9, HST_SELECTED);  

    // Select the 10 hour in all week days  
    m_WeekHours.SetHourDaysState(10, HST_SELECTED); 

    // Select the 11 hour in all week days
    m_WeekHours.SetHourDaysState(11, HST_SELECTED); 

    // Disible the Thursday hours
    m_WeekHours.SetDayHoursState(5, HST_DESIBLED);  

    // Disible the Friday hours
    m_WeekHours.SetDayHoursState(6, HST_DESIBLED);  
}

To get state of hour

Use the function GetHourState(int iDay, int iHour) to get the state of the hour. The class provide different functions to manipulate the state of a hour and block of hours.

// Get state of a hour
int GetHourState(int iDay, int iHour);		

// Set the state of a hour
void SetHourState(int iDay, int iHour, int State);	

// Set the state of the day hours
void SetDayHoursState(int iDay, int State);	

// Set the state of the hour in all week days
void SetHourDaysState(int iHours, int State);	

Conclusion

This article can show how to create own control from basic MFC window class. And demonstrates how to exploit a simple window message to create controls. If you use this control or you fixed bugs, sending mail for me will be a nice idea. Thanks.
