    I need to make a calcualtor (must be able to add, subtract, divide, and multiply). Two text boxes allow you to enter numbers which in turn does the math and prints to a seperate :confused:

          Which is what? You've got to be more specific about what your problem is in order for us to help. For example, I commented that in your first post the sentence ended midstream. So we can only guess or assume what you want. You have two text boxes. I'm assuming you have a bunch of buttons. +, -, /, * I'm assuming you have a textbox or label for the result. What part isn't working? What have you tried already? ColinMackay.net Scottish Developers are looking for speakers for user group sessions over the next few months. Do you want to know more?

            i have two text boxes, and four buttons. Each text box allows for numbers, the buttons are teh math function. They then print the answer onclick to a seperate label. I have tries adding the strings which simply put the two numbers in the box next to one another. I have tries sending the text.tostring function to the label.......

                You need to convert it to an int before you can add them. Use this method: int x = Convert.ToInt32(//put string number in here); int y = Convert.ToInt32(//put string number in here); // do your calculations (x*y, x+y, etc); Wacky waving inflateable arm flailing tube man! - Family Guy

                                He is referring to the fact that you coded:

                                Convert.ToInt32.txtFirstNum;

                                When the example clearly used brackets and specified you needed to pass in a string.

                                Convert.ToInt32(txtFirstNum.Text);

                                ColinMackay.net Scottish Developers are looking for speakers for user group sessions over the next few months. Do you want to know more?

                                  Then you can take the result and assign it to the Text property of your Label. (Remember to convert it to a string when you do that) Does this help?
