Creating a simple calculator in Visual Basic 2015


Hello Jessica!

In this program I will use most of the arithmetic operators that we can use in VB. You just need few controls to make this work. You just need the following controls in your form.

1. 3 Label controls – “1st Value:”, “2nd Value:”, “Answer” for the name properties that is similar above.

2. 3 text boxes – str1 for the name property of the first text box, str2 for the second, and strans for the last box.

3. 6 command buttons – name it according to the operator that you will use for the command buttons like, “cmdadd”, cmdsubtract, etc.

The codes should look like this.

For cmdadd_click() type this:

strans.Text = Val(str1.Text) + Val(str2.Text)

For cmdsubtract_click():

strans.Text = Val(str1.Text) – Val(str2.Text)

For cmddivide_click()

strans.Text = Val(str1.Text) / Val(str2.Text)

For cmdmultiply_click()

strans.Text = Val(str1.Text) * Val(str2.Text)

For cmdmod_click()

strans.Text = Val(str1.Text) MOD Val(str2.Text)

for cmdexponent_click()

strans.Text = Val(str1.Text) ^ Val(str2.Text)

Notice that we used the “Val” to get the numerical value of the string that will be placed in the text boxes.
