Practical No.5
Aim: Design Standard Calculator in Windows Mobile.
1)To create new project
File>>New Project
2)Select Programming language
3)Edit Project name
4)Select Device application
5)Drag Controls as per need
Add Text boxes
Note-Add three text boxes and name it as txt_fn(For first number),txt_sn(For second number) and
txt_opr(For operator).Keep txt_fn and txt_opr text boxes disabled(or Enbled = False) so user cant edit
it.
Add Button & edit Properties
6)Double Click on button & add code
Code for button 1 Click:
privatevoid btn_1_Click(object sender, EventArgs e)
{
txt_sn.Text = txt_sn.Text + "1";
}
Code for button 2 Click:

Insert one tab control and add tabs from tabPages Property from property window
Change the text property of tab pages and add button in that tabpage also change the name and text
property of button to the desired names
For eg in tab 1 the text of the tabpage is changed to “TEXT” and name of the button is changed to
“btn_text”
Right click on form1 and click view code
Add the following function in class Form1
private void DrawString()
{
