WPF does not allow text wrapping for label control.Thus to wrap a label with a fixed width,we have to place the TextBlock control inside the label control and set its TextWrapping property to “Wrap”.

<Label Width=”50″>
<TextBlock TextWrapping=”Wrap”> I am label with width 50</TextBlock>
</Label>

In c# for panel there no property to set border color directly.We can only set the border style using BorderStyle.

To set the border color of a panel,

Step 1 : Set BorderStyle property to None.

Step 2 : Draw a rectangle and set the pen color in paint event of the panel

private void panelpanelbordercolor1_Paint(object sender, PaintEventArgs e)
{
  e.Graphics.DrawRectangle(Pens.Red,
  e.ClipRectangle.Left,
  e.ClipRectangle.Top,
  e.ClipRectangle.Width - 1,
  e.ClipRectangle.Height -1);
  base.OnPaint(e);
}

Step 1
Create your own windows application. Create a new Windows application project in C# and named it as Sample.

Step 2

Design your own application. Here we have a simple login form for example.

Step 3
After completing the design and coding, build the solution of the project in release mode.

Step 4
Check the Release folder for the file “ProjectName.exe”. Here in this example we have the project name as sample so we can find a file with the name Sample.exe. Double click the executable file and check the example.

Step 5
Create a Deployment Project. Select the “Other Project Types” -> “Setup and Deployment” -> “Setup project”. Here we have the setup project for example as “SampleSetup”.

Step 6
Add the Sample.exe project application file inside the “Application Folder”.

Step 7

To make a shortcut for the project right click “File System on Target Machine” and create shortcut of the application. Here in this example the project shortcut is created in program files folder.

Step 8
Create the shortcut of the application.

Step 9
Rename the shortcut of the application.

Step 10
Move the Shortcut file to specified target. Note if you need another shortcut for some other target also create use same steps.

Step 11
Now build the solution in release mode.

Step 12
The setup file created in release folder of the project specified path.

Step 13
Run the setup, step the path to extract.

Step 14
The SampleSetup project is extracted and shortcuts are created. Now run your application.

To make the operations such as copy paste using c#,we have to use the Clipboard Class which provides methods to place data on and retrieve data from the system Clipboard.

Example :-

Copy the text from txtCopy to clipboard

 System.Windows.Forms.Clipboard.SetDataObject(txtCopy.Text, true);

Paste the text from clipboard to txtPaste

IDataObject clipData = Clipboard.GetDataObject();
if (clipData.GetDataPresent(DataFormats.Text))
{
txtPaste.Text = clipData.GetData(DataFormats.Text).ToString();
}
else
{
txtPaste.Text = "Could not retrieve data from the clipboard.";
}

We can Convert text to image in c# using System.Drawing namespace.
Here we create a bitmap image and use its Graphics property to convert text passed to image and place the image in a picture box.

private void TextToImage()
{
Color BackColor = Color.White;
String FontName = "Times New Roman";
int FontSize = 25;
int Height = 50;
int Width = 300;
<span style="color: rgb(56, 118, 29);">
//creating bitmap image
<span style="color: rgb(0, 0, 0);">Bitmap </span></span>bitmap = new Bitmap(Width, Height);
 
<span style="color: rgb(56, 118, 29);">//FromImage method creates a new Graphics from the specified Image.</span>
Graphics graphics = Graphics.FromImage(bitmap);
Color color = Color.Gray;
Font font = new Font(FontName, FontSize); 
 
SolidBrush BrushBackColor = new SolidBrush(BackColor);
Pen BorderPen = new Pen(color);
 
Rectangle displayRectangle = new Rectangle(new Point(0, 0), new Size(Width - 1, Height - 1));
<span style="color: rgb(56, 118, 29);">//Drawing a rectangle and filling the background as white
<span style="color: rgb(0, 0, 0);">graphics</span></span>.FillRectangle(BrushBackColor, displayRectangle);
graphics.DrawRectangle(BorderPen, displayRectangle); <span style="color: rgb(56, 118, 29);">
 
//giving the font and color to the string passed</span>
graphics.DrawString(txtEnter.Text,font,Brushes.Red, 0, 0);
