What is this control?

This is an attempt to reproduce the functionality of MS Outlook Calendar control as it appears in the Calendar view. It supports similar features as the MS Calendar control. This is a work in progress. Study the code in the demo, there you will see how to access the date item data when overriding clicks and double clicks. Below are a couple of screen shots of the control:

Month view

Week view

Introduction

Like many developers I searched within the CodeProject and other sites for a control similar to this one but could not find one so I decided to create my own. I needed a control with similar functionality, but not exactly the same as the Calendar control found in MS Outlook.

This piece or code/control was developed to help me display appointments and tasks in a Real Estate program that I am developing. I did not like the one that was already available but I wanted the look and feel to be similar to MS-Outlook. I hope you will find this control useful and use it in your applications.

What this code provides

• It is completely written using MFC (no ATL, no Unicode, no .NET). If you want this you are free to modify the code.
• This code has been tested in Win 2000 and Win XP Professional. I have not tested it on any other versions of Windows, but the only function I would worry about is GradientFill, but according to MSDN it is available as of Win 98 so it would work fine from that version on.
• This code compiles successfully in VS 6 and VS .NET 2003.
• This is a work in progress so further additions to the code will be coming.
• Does not support date items of more than one day. This is a feature I will be adding later.
• Does not support drag-and-drop of date items from one date cell to another. This is a feature I will be adding later.

One of the things I learned about the original Outlook Calendar control after I created this control was that it can display week views from 1 to 6 weeks at a time. This is one of the modifications I will be making to this control in the near future.

Background

The code and its classes in this article provide all the functionality to not only display a Calendar control in Week or Month views but also to include and display entries (Appointments/Tasks) for the selected dates. Although this code does not provide the dialog boxes or windows necessary to enter entries it does provide you with the methods, properties and overridables necessary to create, modify and delete these entries.

I know this code is not perfect and that someone may actually find a better way to paint the control. I have done all that I can to make sure the painting of different views are as efficient as possible. Of course, if I make further enhancements or fixes to the code or if any of you come up with fixes, I will update this article.

Using the code

1. The first step in using the CWVDateCtrl class is to add the following files to your project:
   • WVDateCtrl.h/.cpp
   • WVCellData.h/.cpp
   • WVCellDataItem.h/.cpp
2. You will also need to add a library link to the project.
   • For VS 6, click on Project + Settings... (Alt+F7) to display the Project Settings dialog box.
     1. On the Settings For... dropdown ListBox select All Configurations.
     2. Next, click on the Link tab and enter "msimg32.lib" within the Object/library modules. This library is needed to use the GradientFill Windows function, which is used to highlight the current day of the Month or Week.
   • For VS 7, click on the Project + <ProjectName> Properties... menu option to display the Project Property Pages dialog box.
     1. Select All Configurations from the Configuration: dropdown ListBox.
     2. Click on the Linker option from the tree control.
     3. Next click on Input to display the input values.
     4. For Additional Dependencies enter "msimg32.lib". This library is needed to use the GradientFill Windows function, which is used to highlight the current day of the Month or Week.
     5. Click on the OK button.

You also need to add a custom control object within your FormView or Dialog Window. Make sure to name the class: DBSWMDateCtrl.

Visual Studio 6

Visual Studio .NET 2003

Now we create the variable for this control. Assign the variable name m_WVCtrl by pressing the right mouse button on the Dialog or FormView class and clicking the Add Member Variable... menu option. Enter CWMDateCtrl as the variable type and m_WVCtrl as the variable name.

Next, you need to attach the variable name to the custom control. Within the FormView or Dialog class code, locate the DoDataExchange procedure and add the following code anywhere after the //}}AFX_DATA_MAP line:

DDX_Control(pDX, IDC_CALCTRL, m_WMCtrl);

Now, within the FormView or Dialog box (usually within OnInitialUpdate or OnInitDialog) enter the following lines of code. You can initially display the Calendar control in Month or Week view by simply specifying WV_MONTHVIEW or WV_WEEKVIEW. This method is explained in more detail below:

COleDateTime dtS = COleDateTime::GetCurrentDate();
// Display Calendar in Month View

m_WVCtrl.SetCurrentDate(dtS, FALSE, WV_MONTHVIEW);

or

COleDateTime dtS = COleDateTime::GetCurrentDate();
// Display Calendar in Week View

m_WVCtrl.SetCurrentDate(dtS, FALSE, WV_WEEKVIEW);

If you need to change the view of the control at runtime you can use the SetView method:

m_WMCtrl.SetView(WV_WEEKVIEW, TRUE);

or

m_WMCtrl.SetView(WV_MONTHVIEW, TRUE);

When you compile your code and display the window which contains this custom control you should see the Calendar control displayed in Week or Month view.

long CWMDateCtrl::InsertItem(COleDateTime dtStart, COleDateTime dtEnd, CString strLine /*=""*/, int nImage /*=-1*/)

Description

Inserts a date item into the custom control. For an item to be displayed within the control the first parameter of this method should be within range of the date set by the SetCurrentDate method. The next two parameters are optional and are used to specify if the date item time is displayed using regular (FALSE) or military (TRUE) time and which image from an attached image list is used when painting the date item.

Syntax

// Set WVCtrl date for week display

dtS.SetDate(2005, 2, 19);

void CWMDateCtrl::SetCurrentDate(COleDateTime dtDate, BOOL bMilitaryTime /*= FALSE*/, int nView /*= WV_WEEKVIEW*/)

Description

This method is used to specify the date that is to be used as the current date, if we are displaying the date item times using Military or Regular time and the type of view to be used. Using this method you have to specify a date, preferably the current date (this would be the highlighted date within the control). This control would take this date and determine which other dates are to be painted based on the specified view.

Syntax

COleDateTime dtToday = COleDateTime::GetCurrentTime();

// Display calendar in month view and 

// today's date would be highlighted.

m_WVCtrl.SetCurrentDate(dtToday, FALSE, WV_MONTHVIEW);

CBitmap bmpImgSm;
m_ImgList.Create(16, 16, ILC_COLOR24 | ILC_MASK, 0, 1);

// Load 256 color bitmap containing the images...

bmpImgSm.LoadBitmap(IDB_BMPREMINDER);

// Place bitmap into image list...

m_ImgList.Add(&bmpImgSm, RGB(0, 255, 0));

// Attach image list to the Calendar Control

m_WVCtrl.SetImageList(&m_ImgList);

void CWMDateCtrl::SetItemColor(long nItem, COLORREF clrItem)

Description

Use this method to set or change the background color of individual date items. This is useful to identify the type of appointments and tasks based on color.

Syntax

dtSDate.SetDateTime(2005, 8, 6, 12, 00, 0);
// 45 minutes for lunch

dtWDate.SetDateTime(2005, 8, 6, 12, 45, 0);    
// Display as a task, use task image

int nItem = m_WVCrtrl.InsertItem(dtSDate, dtEDate, 
                            "Lunch with Rolando", 1); 
// Set appointment to green color

m_WMCtrl.SetItemColor(nItem, RGB(0, 255, 0)); 


dtSDate.SetDateTime(2005, 8, 6, 8, 30, 0);
// 2 hour appointment

dtWDate.SetDateTime(2005, 8, 6, 10, 30, 0);    
nItem = m_WVCrtrl.InsertItem(dtSDate, dtEDate, 
                             "Sales meeting", 0);
// Set appointment to blue color

m_WMCtrl.SetItemColor(nItem, RGB(0, 0, 255));

void CWMDateCtrl::SetItemData(long nItem, DWORD dwData)

Description

This function sets the 32-bit application-specific value associated with the item specified by nItem.

Syntax

int nItem = m_WVCtrl.InsertItem(dtS, dtE, "Lunch time");
// 999 use this internal value

m_WVCtrl.SetItemData(nItem, 999);

void CWMDateCtrl::SetMilitaryTime(BOOL bMil)

Description

Use this method to set or change the display of date item times. Setting the parameter to TRUE will paint the date item times using Military time, otherwise Regular time is used. This method affects the entire Calendar control.

Syntax

m_WVCtrl.SetMilitaryTime(TRUE);

void CWMDateCtrl::SetView(int nV, BOOL bRedraw /*=TRUE*/)

Description

Use this method to change the way the Calendar control is painted. The values which can be used are WV_WEEKVIEW or WV_MONTHVIEW.

Syntax

if (m_WVCtrl.GetView() == WV_WEEKVIEW)
    m_WVCtrl.SetView(WV_MONTHVIEW);
else
    m_WVCtrl.SetView(WM_WEEKVIEW);

Override functions

Currently, there are only two messages that you can override in order to interact with this control. The Calendar control will notify the parent window with a NM_CLICK and NM_DBLCLK. To override these notification messages follow these instructions:

1. Add the following PROTECTEDmember function to your FormView or dialog box to process double click notifications from the Calendar control:

   afx_msg void OnCellDblClick(NMHDR *pNotifyStruct, 
          LRESULT* pResult); (Left mouse Double click)
   afx_msg void OnCellClick (NMHDR *pNotifyStruct, 
                 LRESULT* pResult); (Left mouse Click)

2. Next add the following line to your message map:

   ON_NOTIFY(NM_DBLCLK, IDC_CALCTRL, OnCellDblClick)
   ON_NOTIFY(NM_CLICK, IDC_CALCTRL, OnCellClick)

3. Edit the OnCellDblClick/OnCellClick member function. To access the Calendar information you need to cast pNotifyStruct to NM_WVCELLDATA.

   NM_WVCELLDATA *pData = (NM_WVCELLDATA *)pNotifyStruct;

NM_WVCELLDATA notification structure

typedef struct tagNM_WVCELLDATA {
    NMHDR hdr;
    CWVCellData *pCell;
    CWVCellDataItem *pItem;
    int   iRow;
    int   iColumn;
    BOOL bDNFClicked;
    long nItem;
} NM_WVCELLDATA;

CWVCellData *pCell;

This member variable contains all the information regarding the actual date cell of the Calendar control. You have access to many functions and procedures which directly affect the appearance and behaviour of the Calendar date cell.

Take a look at the WVCellData.h and WVCellData.cpp files for more information on this Calendar object. I believe all the procedures and functions are self explanatory.

CWVCellDataItem *pItem;

This member variable is usually NULL unless the user clicks or double clicks on a data item within a date cell of the Calendar control. You have access to functions and procedure which directly affect the particular date item data.

Take a look at the WVCellDataItem.h and WVCellDataItem.cpp files for more information on this Calendar date item object. I believe the procedures and functions are self-explanatory.

int iRow;

int iCol;

These two member variables contain the mouse pointer coordinates where the actual click or double click has occurred.

BOOL bDNFClicked;

This is a special member variable. This member variable will have a value of TRUE only when the user clicks on the Does Not Fit rectangle which is located at the bottom right part of any Calendar date cell which can't display all of the date items within the available cell area.



When the user clicks on this object, the Calendar control will notify the parent window as if the user has double clicked the cell at which point this member variable will be set to TRUE. It is up to you to decide how you want to handle this. I use this feature to change the Calendar view from Month to Week view.

long nItem;

This is the ID number given to the Calendar date item (pItem) when the InsertItem function is used.

Look at the OnCellClick and OnBtndeleteitem member functions within the demo program to find out how I have used this member variable (CalCtrlDlg.cpp).

SetTime() shows DATE instead of TIME in both controls... AlexEvans 23:09 27 Aug '08   Hi Rolando, In the small pop-up dialog, it shows correctly the TIME in your sample application, BUT - after copying te required files into my application this shows the DATE instead, in both the FROM and TO fields. I checked ALL the attributes of this doalog in the sample, and in my application, and they are the same. I did make a small change in the OnInitDialog() just so that it shows the DATE in thye caption in dd/mm/yyyy format instead of the US format, but even after changing it back, it still missbehaves... Below is the code fragment of the OnInitDialog(), I am checking the return value as you can see, and it returns '1' in both cases... Hope you can help me figure out why and how to fix it. Thanks in advance Alex BOOL CDlgDateItem::OnInitDialog() { CDialog::OnInitDialog(); CString strBuf; BOOL bRC = 0; if (bAddMode) strBuf.Format("Add Date Item - %s", dtSDate.Format("%d/%m/%Y")); else strBuf.Format("Modify Date Item - %s", dtSDate.Format("%d/%m/%Y")); SetWindowText(strBuf); m_Subject.SetWindowText(strSubject); bRC = m_FromTime.SetTime(dtSDate); bRC = m_ToTime.SetTime(dtEDate); Sign In·View Thread·PermaLink 2.00/5 (1 vote) NIce job, but...

However, I am working on a project for a friend and I would very much like to use this control. I am a C# programmer of moderate knowledge and I have been trying to create a workable Windows form control or something so that I can utilize this Calendar Control in my C# project. Has anyone already built a COM for this control that can be used in VS 2005? If not, can anyone give me a bit of guidance on how I would go about making one myself? I have tried creating an MFC DLL. I am able to compile but unable to actually use the dll once created... perhaps I'm missing something obvious. I have tried creating a CLR Windows Form Control Library. Which won't even compile (generating 480+ compile errors). Thank you for your time...

Willem_Le_Roux 6:12 10 Jul '06   Hey Ronaldo! Great control! It looks smashing and I am looking forward to using it in my own applications. I have seen on the boards that you are thinking about incorporating the day view into your application. Super idea! Keep me posted! Now, there are a few questions that I would like to ask. If I am in the month view and I filled up all the space with appointments/tasks, how do I have a look at the appointments/tasks that is not visible? You say that you use “BOOL bDNFClicked” to switch to week view. If already in week view, could you make it switch to day view? Could you perhaps make a little list appear with all the appointment items that are not displayed? And then when you click on an item in that list, it shows the details for those specific entries. I LOVE your control and please keep me posted as to when you are planning any updates! I like it A LOT! I see you have won an award for this one as well! Congratulations! Willem Le Roux Sign In·View Thread·PermaLink Re: Wow! Excellent control! Rolando E. Cruz-Marshall 16:05 10 Jul '06   Hey Willem! Thanks for your kind words. As fas as the Day View goes, I worked on it for a while but the coding approach was wrong since the control took a while to draw itself. I also had scrolling problems. Unfortunately I have not continued development on this control and I currently do not have the time for it. I can suggest that when clicking on the DNF button, on the bottom right corner of the month cell, you can query the database and display a dialog box with the list of all items for the day cell. You could do the same in the week view, if you want. The control notifies the parent window when this button is clicked. (Make sense? ) I am currently developing a new version of a program I've developed and will propably be using this control. If I make any changes to the code I will post it here once again.

Rolando Sign In·View Thread·PermaLink Small bug in GetDateRange Tom Archer - MSFT 15:55 19 Feb '06   Great class! It's definitely made my app much better looking and usable. Having said that, I have found one small bug in GetDateRange. It correctly "walks" back from the current date until the day == Monday (which to COleDateTime::GetDayOfWeek is 2). COleDateTime dtDate = dtCurrentDate; while (dtDate.GetDayOfWeek() != 2) dtDate -= 1; pStartData = GetCellByDate(dtDate); However, for end date, it then tries to walk forward until the COleDateTime::GetDayOfWeek == 7. The problem with that is that the calendar displays Sunday as the last day of the week and 7 for the COleDateTime control is Saturday. Therefore, in cases where the current day is Sunday, the control incorrectly returns the following week's Saturday as the end of the current week. In my own version of the class, I solved this by simply adding 6 to the correctly determined start of week value. dtDate += 6; pEndData = GetCellByDate(dtDate); Tom Archer (blog) Program Manager MSDN Online (Windows Vista and Visual C++) MICROSOFT Sign In·View Thread·PermaLink Re: Small bug in GetDateRange Rolando E.

Sign In·View Thread·PermaLink Re: Use in VB yangyancheng 20:09 7 Jul '06   First ,use vs2005. then use VC.NET 2005 to write a .net usercontrol which contains this mfc control .(because VC 2005 can use both clr and mfc in the same project) third invoke the .net usercontrol in vb.net. I have done this these days, and the vb program works well. sfcyyc Sign In·View Thread·PermaLink 3.50/5 (2 votes) Way to go Rolando! c0d3m@n 14:38 8 Feb '06   This was just what I was looking for. You mentionned that you were going to add multi-day event support and drag and drop... I'd be super duper interested in those extra features. Have you had the chance to add those yet? Will you share them as well? =) Thank you so much! Again, terrific job and congratulations on the award!

Rolando Sign In·View Thread·PermaLink Showing a different month TWS_Dave 4:25 17 Jan '06   Hi Like most of the other comments I think this control is great, but I would like some advice on the best way to show a month other than the current month. The only way I can see to do this is to set the current date to a date within the month to be shown but this would highlight a cell as if it were today and I would like to avoid this. Has anybody got any other ideas - Am I missing something obvious here?? Thanks for your help Dave Sign In·View Thread·PermaLink 2.00/5 (2 votes)
