I'm assuming you're using MFC. Make sure the radio buttons belong to the same group. You can do this by setting the group property of the first radio button to true. And the rest of the radio button must follow the first in order. Now associate an int variable with the first radio button by right clicking on it and selecting "Add Variable". Similarly associate an int variable with the edit box. In the button click handler, first call
UpdateData. This will update the UI selection to the variables just added. Check the value of the radio button variable to determine the option selected. It will be 0 for first, 1 for second and so on. Do your calculation and set the result to the variable associated with the edit box. Finally callUpdateData(FALSE)to set the variables back to the UI.«_Superman_» I love work. It gives me something to do between weekends.

Superman has given a very good explanation on how to implement this problem. Go Ahead and do the implementation. i am sure it is not a difficult task to complete. When you are stuck there are people to help you. On selecting the radio button you can pass the value to the function in the command button which does the calculation and display the result in the textbox.

thanks for the reply... my problem is that i dont have a sample code on how to pass the value of the function to the command button. If i tried to use if else statement the system will say syntax error :( here is my sample code: UpdateData(); if m_button1.Select = true m_edit2 = 0; else m_edit2 = m_edit1 * .9; UpdateData(false); i cant connect to the radio button...please help me... thank you and i will wait for a reply. neil

Create a Global variable. assign the value and then pass the value to the command button. and why are you using an if-else statement for this?

hehehe...that's the reason why i posted this query because i only have little knowledge on c++. I am still on the process of studying this language. Please sir give me website to where i can look for sample codes on c++. I really need samples very badly... thank you again. neil

Lose the calls to
UpdateData(). They are completely unnecessary and only add to your confusion. You can easily have aCButtonmember variable associated with each radio button, and can call the button'sGetCheck()method to see if it is checked or not. BTW, when pasting code snippets, see #5 here. As it is, your code will not compile."Old age is like a bank account. You withdraw later in life what you have deposited along the way." - Unknown

What is this supposed to mean? What is a "command button?"
