To get ShortMonth in C#.net

Hi,
Use the below coding to get the short month,
public static string GetShortMonth(object aDate)
{
DateTime actualDate = (DateTime)aDate;
int day = actualDate.Day;
int monthNumber = actualDate.Month;
string month = "";
if (monthNumber == 1)
{
month = "Jan,";
}
else if (monthNumber == 2)
{
month = "Feb,";
}
else if (monthNumber == 3)
{
month = "Mar,";
}
else if (monthNumber == 4)
{
month = "Apr,";
}
else if (monthNumber == 5)
{
month = "May,";
}
else if (monthNumber == 6)
{
month = "Jun,";
}
else if (monthNumber == 7)
{
month = "Jul,";
}
else if (monthNumber == 8)
{
month = "Aug,";
}
else if (monthNumber == 9)
{
month = "Sep,";
}
else if (monthNumber == 10)
{
month = "Oct,";
}
else if (monthNumber == 11)
{
month = "Nov,";
}
else if (monthNumber == 12)
{
month = "Dec,";
}
int year = actualDate.Year;
return month + " " + day.ToString() + " " + year.ToString();
}

To Get ShortDate in C#.net

Hi,
we can get the ShortDate using the following function,

public string GetShortDate(object aDate)
{
DateTime actualDate = (DateTime)aDate;
string shortDate = "";
string month = actualDate.ToLongDateString();
string[] mon = month.Split(',');
string date = mon[1];
string year = mon[2];
shortDate = date + year;
return shortDate;
}

To GetSubString in C#.net

Hi,
We can reduce the length of the string using getSubString function, so that the length of the string is reduced to our required length.

public string GetSubString(Object str,int len)
{
string name="";
name=str+"";
if(name.Length>len)
{
name=name.Substring(0,len);
}
return name;
}

Implementing Paging in Datalist

Hi,
To implement paging concept in DataList use the following coding.
Here PagedDataSource is used to do paging in DataList.
Consider u r having one label named lblPagingTop to list no.of.records per page(eg. 2/6),
two hyperlinks topNextHyperLink,topPrevHyperLink for Paging.

In Code-behind have the following,

public void sampleStudPaging()
{
PagedDataSource sampleStudPagedDataSource = new PagedDataSource();
int currentPage;
try
{
if (sampleStuds.Length == 0)
{
topPrevHyperLink.Visible = false;
topNextHyperLink.Visible = false;
topLinkLabel.Visible = false;
}
if (sampleStuds.Length > 0)
{
sampleStudPagedDataSource.DataSource = sampleStuds;
sampleStudPagedDataSource.PageSize = 2;
sampleStudPagedDataSource.AllowPaging = true;
if (Request.QueryString["p"] != null)
{
currentPage = int.Parse(Request.QueryString["p"].ToString());
}
else
{
currentPage = 1;
}
sampleStudPagedDataSource.CurrentPageIndex = currentPage - 1;
if (!sampleStudPagedDataSource.IsFirstPage)
{
topPrevHyperLink.NavigateUrl = Request.CurrentExecutionFilePath + "?p=" + Convert.ToInt32(currentPage - 1);
}
else
{
topPrevHyperLink.NavigateUrl = "#";
}
if (!sampleStudPagedDataSource.IsLastPage)
{
topNextHyperLink.NavigateUrl = Request.CurrentExecutionFilePath + "?p=" + Convert.ToInt32(currentPage + 1);
}
else
{
topNextHyperLink.NavigateUrl = "#";
}
lblTopPaging.Text = "Page: " + (currentPage).ToString() + " of " + sampleStudPagedDataSource.PageCount.ToString();
SampleStudDataList.DataSource = sampleStudPagedDataSource;
SampleStudDataList.DataBind();
if (currentPage == 1)
{
topPrevHyperLink.Visible = false;
topLinkLabel.Visible = false;
}
if (currentPage == sampleStudPagedDataSource.PageCount)
{
topNextHyperLink.Visible = false;
topLinkLabel.Visible = false;
}
if (sampleStudPagedDataSource.PageCount == 1)
{
topPrevHyperLink.Visible = false;
topLinkLabel.Visible = false;
}
}
}
catch (Exception ex)
{
}
}

To drag image inside PictureBox

Hi,
we can drag image inside the pictureBox.
Please follow the steps one by one.

1. Place PictureBox in the form.
2. Set the following Properties for the PictureBox

• BackColor -> Transparent
• BackgroundImage->Give the image path of PNG file from your system.
• BackgroundImageLayout ->Stretch
• SizeMode -> Autosize

3. Create the Class named DraggableImage and write the following coding that
contains details about Image,Width,Height and Location.
class DraggableImage
{
public Bitmap img;
public Point Loc;
public int Width;
public int Height;
public DraggableImage(Bitmap bmpImg,Point loc)
{
this.img = bmpImg;
this.Loc = loc;
this.Width = bmpImg.Width;
this.Height = bmpImg.Height;
}
}

4. In the Form use the following coding,
public partial class Form1 : Form
{
DraggableImage di = new DraggableImage(Properties.Resources._1, new Point(0, 0));
int mx, my;
[Category("Property")]
[Description("Get and Set the draggable Image")]
public Bitmap DragImage
{
get { return di.img; }
set { di.img = value; Refresh(); }
}

public Form1()
{
InitializeComponent();
this.SetStyle(ControlStyles.AllPaintingInWmPaint, true);
this.SetStyle(ControlStyles.UserPaint, true);
this.SetStyle(ControlStyles.DoubleBuffer, true);
}

private void Form1_Load(object sender, EventArgs e)
{

this.DragImage =(Bitmap)QDOES.ImageOptimizer.ResizeToMaxSize(di.img,
pictureBox1.Width, pictureBox1.Height, 96, 96);
di.Loc = new Point(pictureBox1.Left,pictureBox1.Top);
this.MouseMove += new MouseEventHandler(Form1_MouseMove);
this.MouseDown += new MouseEventHandler(Form1_MouseDown);
this.pictureBox1.MouseDown += new MouseEventHandler(pictureBox1_MouseDown);
this.pictureBox1.MouseMove += new MouseEventHandler(pictureBox1_MouseMove);

}

private void Form1_MouseMove(object sender, MouseEventArgs e)
{
if (e.Button == MouseButtons.Left)
{
di.Loc.X = e.X - mx + di.Loc.X;
di.Loc.Y = e.Y - my + di.Loc.Y;
mx = e.X;
my = e.Y;
Refresh();
}
}

private void Form1_MouseDown(object sender, MouseEventArgs e)
{
mx = e.X;
my = e.Y;
}
protected override void OnPaint(PaintEventArgs e)
{
base.OnPaint(e);
if (di != null)
{
e.Graphics.DrawImage(di.img, di.Loc);
}
}

private void pictureBox1_MouseMove(object sender, MouseEventArgs e)
{
if (e.Button == MouseButtons.Left)
{
di.Loc.X = e.X - mx + di.Loc.X;
di.Loc.Y = e.Y - my + di.Loc.Y;
mx = e.X;
my = e.Y;
Refresh();
}
}

private void pictureBox1_MouseDown(object sender, MouseEventArgs e)
{
mx = e.X;
my = e.Y;

}


}
