With Persian Diary, you can navigate in Persian Calendar and store your memorandums

Introduction

With this software, you can navigate the Persian Calendar and you can add your memorandum for each day.

Using the Code

I've created this project with .NET Framework 3.5 SP1, so you need to install it to use this project.
I've also used a SQL database(mdf) to store the data, so at least you have to install SQL Express 2008.

Creating the UI

The best way for creating a software UI like this is to use a Stack.

Then we should use UniformGrids and Grids in the Stack to create the UI.
For instance, the XAML code for 1 in the above figure is:

<StackPanel x:Name="stackPanel">
    <StackPanel.BitmapEffect>
        <BlurBitmapEffect Radius="0"/>
    </StackPanel.BitmapEffect>
    <Grid HorizontalAlignment="Stretch" VerticalAlignment="Center" 
        x:Name="header" MinHeight="70">
        <Grid.ColumnDefinitions>
            <ColumnDefinition Width="0.135*"/>
            <ColumnDefinition Width="0.102*"/>
            <ColumnDefinition Width="0.494*"/>
            <ColumnDefinition Width="0.14*"/>
            <ColumnDefinition Width="0.129*"/>
        </Grid.ColumnDefinitions>
        <TextBlock FlowDirection="RightToLeft" Language="fa-ir" 
            FontSize="36" x:Name="TextBlockThisMonth" HorizontalAlignment="Center" 
            Grid.Column="2" VerticalAlignment="Center" Margin="0,0,0,0" 
            FontFamily="Arial">تاریخ</TextBlock>

        <Button x:Name="previousMonth" Content=" ماه قبل &gt; " 
            Grid.Column="3" VerticalAlignment="Center" Click="previousMonth_Click" 
            HorizontalAlignment="Center" />
        <Button x:Name="nextMonth" Content=" &lt; ماه بعد " Grid.Column="1" 
            HorizontalAlignment="Center" VerticalAlignment="Center" 
            Click="nextMonth_Click" />

        <Button x:Name="previousYear" Content=" سال قبل &gt;&gt; " 
            Grid.Column="4" HorizontalAlignment="Center" VerticalAlignment="Center" 
            Click="previousYear_Click" />
        <Button x:Name="nextYear" Content=" &lt;&lt; سال بعد " 
            HorizontalAlignment="Center"  Click="nextYear_Click" 
            VerticalAlignment="Center"  />

I also created a couple of Storyboards to show and hide the below panel.
This panel updates the database with your input data.

The C# Code

In Persian Calendar, we have 12 months that I have shown in the following code snippet:

//Season { MonthName(nomber of days in the month) ...}
Spring { Farvardin(31), OrdiBehesht(31), Khordad(31) }
Summer { Tir(31), Mordad(31), Shahrivar(31) }
Autumn { Mehr(30), Aban(30), Azar(30) }
Winter { Day(30), Bahman(30), Esfand(30 or 29) }

Fortunately there is a class in .NET for creating Persian Calendar and I've used it.

PersianCalendar persianCalendar = new PersianCalendar();

The main method in this project to create a Persian month is calculateMonth.

/// <summary>
/// The main method to show the calendar
/// This method shows `thisMonth` in `thisYear`
/// </summary>
void calculateMonth(int thisYear, int thisMonth)
{
    try
    {
        yearForNavigating = thisYear;
        monthForNavigating = thisMonth;

        DateTime tempDateTime = persianCalendar.ToDateTime(yearForNavigating, 
        	monthForNavigating, 15, 01, 01, 01, 01);

        int thisDay = 1;
        TextBlockThisMonth.Text = "";
        TextBlockThisMonth.Text =
            monthForNavigating.convertToPersianMonth() + " " +
            yearForNavigating.convertToPersianNumber();

        //Different between first place of calendar and first place of this month
        //اختلاف بین خانه شروع ماه و اولین خانه تقویم            
        string DayOfWeek = persianCalendar.GetDayOfWeek(persianCalendar.
        	ToDateTime(thisYear, thisMonth, 01, 01, 01, 01, 01)).ToString();
        int span = calculatePersianSpan(DayOfWeek.convertToPersianDay());

        decreasePersianDay(ref thisYear, ref thisMonth, ref thisDay, span);

        string persianDate;//حاوی تاریخ روزهای شمسی Contains the date of Persian
        string miladiDate;//حاوی تاریخ روزهای میلادی Contains the date of Christian
        string hijriDate;//حاوی تاریخ روزهای قمری Contains the date of Hijri

        string tooltip_context = "";//Contains the text of tooltip

        ////////////////////////////////////

            	thisDay, 01, 01, 01, 01);

            increasePersianDay(ref thisYear, ref thisMonth, ref thisDay, 1);
        }
    }
    catch (Exception ex)
    {
        MessageBox.Show(ex.Message, "Exception", MessageBoxButton.OK, 
        	MessageBoxImage.Error);
    }
}

Then I've used LINQ to update the database.
First I've added a LINQ to SQL class:

Then I designed DataClasses1.dbml:

Then we can update the database easily with a LINQ query.
For instance, I wrote this method to search shamsi table.

/// <summary>
/// Searches the Database shamsi table
/// </summary>
/// <returns>If the input data is found in the table return true, else 
/// return false</returns>
bool searchShamsiTable(int year, int month, int day)
{
    bool result = false;
    try
    {
        int? id = null;
        id = (from q in db.shamsis
              where (q.year == year && q.day == day && q.month == month) 
              	|| (q.anniversary == true && q.month == month && q.day == day)
              select q.id).First();
        if (id != null) result = true;
    }
    catch { result = false; }
    return result;
}

Other methods are simple and easy to learn and I've explained them with some comments.

Point of Interest

The point of interest in this project (for me) was, using a WinForm control in WPF.
I've used a WinForm Masked TextBox for input year.

For using a WinForm Masked TextBox in a WPF App: I added these DLLs to my references:

WindowsFormsIntegration.dll
System.Windows.Forms.dll

Then I added the following line within Window tag in the XAML source:

xmlns:wf="clr-namespace:System.Windows.Forms;assembly=System.Windows.Forms"

At last, I added the MaskedTextBox control to my WPF App with WindowsFormsHost tag.

<WindowsFormsHost Grid.Column="0" FontSize="13" 
	VerticalAlignment="Center" HorizontalAlignment="Center" 
    Width="70" Height = "25">
	<wf:MaskedTextBox x:Name="textBoxYear" Mask="0000"/>
</WindowsFormsHost>

Further reading about WindowsFormHost can be done here.
