[Windows Form with visual C#] - Problem with data conversion
-
Hello to all, now I expose my problem: I'm developing a program with Visual C# express to calculate the ratio of my radio-controlled model! How do I enter the following input data: Number of teeth of spur gear (int), internal ratio (float), and ratio that you want to get (float). I need as output the number of teeth of the pinion to use. The pinion is obtained with the following formula: Pinion = (Spur Gear * Ratio) / Internal Ratio My problem is that I don' t know how to operate the data conversions, because obviously I can' t write:
Int SpurGear = textbox1.Text;
Float Ratio = textbox2.Text;
Float InternalRatio= textbox3.Text;
Float Pinion = (SpurGear * Ratio) / InternalRatio;
label1.text= Pinion;Etc Etc Someone can help me?

Try:
Int SpurGear = int.Parse(textbox1.Text);
Float Ratio = Float.Parse(textbox2.Text);
Float InternalRatio= Float.Parse(textbox3.Text);
Float Pinion = ((Float) SpurGear * Ratio) / InternalRatio;
label1.text= Pinion.ToString();No trees were harmed in the sending of this message; however, a significant number of electrons were slightly inconvenienced. This message is made of fully recyclable Zeros and Ones

Most of the value types have Parse method for data conversion. Don't forget to have a look at TryParse methods too :)

Hi, a TextBox contains text, so Text returns a string, not a number. converting strings to some numeric type is called parsing, use the Parse or TryParse method of the target type, e.g.
double.TryParse(...), see documentation. :)Luc Pattyn
