hello everyone =)

can someone help me please to solve somthing..?

I have difficulties in my calculator program.

I am using the 2005/2008 edition of vb express.

I created a calculator with only one textbox, and i can't figure it out how to insert 2 values and make the arithmetic operation work.

i have succeeded to insert one value, but i need that the number on the textbox will remain even if i press the (+,-,/ etc) and just when i will start to insert an other value so the previous one will disappear and the new one will display on the textbox and the secoend variable will get the value so i can make the arithmetic operation.

thanks a lot for your help.
