im trying to do some calculations with constants and text boxes.

i want them to multiply the value in the text box to the value in the constant when the user clicks on the menu item.

here is the code i have and some things i have tried:

		   const int a = 15;
			const int b = 50;

			int c = Convert.ToInt32(aTextBox.Text);

i have tried:

a * c;

a * aTextBox.Text;

im still new to C# so anything that isn't obvious escapes me

EDIT i ment a*c not a*b i changed it now

Did it give you any errors? When you debuged what was the value in c?

const int a = 15;
			const int b = 50;

			int c = Convert.ToInt32(aTextBox.Text);
			int results = c*a;

when i try to display the answer i tells me Cannot inplicitly convert int to string.

i tried:
results.ToString();

didnt work though

Is this a console app?

Console.WriteLine(results.ToString());

[lithomander]

no its a windows app as far as i know

Ok try this.

		   int c = Convert.ToInt32(this.aTextBox.Text.Trim());
			int results = c * a;
			MessageBox.Show(results.ToString());

Then put a break point on int c and walk it through and let me know what it does.

that code is brilliant, if i wanted to put it into a .text property would i simply change messagebox.show to textbox.text?

or would it be more complex than that?

[egof]

Yep that easy. aTextBox.Text=??;

[lithomander]

what does this mean:

Error 2 'System.Windows.Forms.TextBox' does not contain a definition for 'text' and no extension method 'text' accepting a first argument of type 'System.Windows.Forms.TextBox' could be found (are you missing a using directive or an assembly reference?)

code:

aTextBox.text = (results.ToString());

[egof]

when your typing your code you need to be lazy let the auto populate work for you it will save you typos. Type in "aTextBox." then view the drop down hit the letter t and I believe Text should popup.

thanks i think that solves the problem
