C# All Concepts required in form applications

Massked text Box

If(e.keycode == keys.Enter)

MessageBox.Show(“Hello hello”);

If(e.keycode == key.A)

MessageBox.Show(“you have pressed A”);

For clear

dialogResult abc = messagebox.show(“are you sure you want to clear”,”warning”,MessageBoxButtons,YESNo);

if(abc == system.Windows.Forms.DialogResult.Yes)

txtName.Text = txtUniv.Text = txtNIC.Text = “”;

else

MessageBox.Show(“values not Cleared”);

numMeric up down

value = 100

increment 1

through code

in form_Load

numericupdown.Maximum = 15;

numericupdown.Minumum= -5;

numeric up down incement = 2;

numeric up down value =3;

if press esc form is closed;

then we make button close form

and set text btnkillform

eniveroment.Exit();

1 way

in properties there is cancel button where we slect close button

if there is no button

then we declare an event key down

then

if(e.keycode == keys.Escape)

this.close();

way is to  copy this code in all the buttons of text boxes so we can terminate when press escape

how enter key works

if press enter key then show input works

click on form go to accept button then we go to showinputbutton in properties

picturebox

when I press button then image will be showed

I go to form1_load an write

pictureBox1.Visible = true;

how put image in button

then we go to google

accept button in search

then we choose button image then view original image then save it

close the form and then

go to desin then remove text from button image will be clear then go to properties of button then

select back ground image accept button then select stretched then its awesome works

and then we place icon buttons

then combo box

also called drp[ down list

go to properties then go to items and then write

apple pine orange

then I want if I run the option must show

drop down style is drop down list

what I want if I select the and choose button butt press show item is selected.

Messagebox.show(Comboxbox1.Text);

Show respectively

Then I want from code then form1_load

And set autmaticall selected index 2

Comboxbox1.SelectedIndex =2;

List items

Liost box just like combox box items place items

And wirte in form1_load

Listbox.Selectedindex = 2;

In btn show

Messagebox.Show(listbox1.Text);
