Question

I have numerous methods returning voids that I written for my program in C# forms which I use all the time. Since I need to use them on multiple forms, I figure there must be better way to save them in some Class, Data rather then copying them for every form individually… I am quite new at this so I am looking for advice. What to do?

Sample: I’ve created methods similar to these:

private void NewBtn(string nName, int locX, int locY)
private void NewPic(string nName, int locX, int locY, int SizX, int SizY, Image Img)

Now, instead of copying them in every form I want to write them in some other file and still be able to call them in any new form I add. Suggestions?

Answer 1

Ok everyone else has taken a shot at this I might as well too.
I think this answer has been suggested but maybe not explained clear enough.

add a new class to your project
in Visual C# you would go
Project -> add Class

Give your Class a name and click ADD

Normally I name this class Tools

then inside the Tools.cs file

EDITED:
I was looking at some of your other questions and I think I found the actual method you are trying to implement. As someone had commented in that thread you really need to use better names, I have made changes to the method to hopefully simulate what you are going for. For anyone trying to understand this please see C# graphics, paint, picturebox centering

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Windows.Forms;

namespace MyNameSpace //Make sure this matches your projects namespace
{
    class Tools
    {
        //Because this is outside the form that is calling it, you cannot access
        //the actual form or panel where you wish to place the button(PictureBox)
        //so instead of returning void (which is nothing) we return the newly
        //created Button(PictureBox)



        public static PictureBox NewBtn(string nName, int locX, int locY)
        {
            Font btnFont = new Font("Tahoma", 16);
            PictureBox S = new PictureBox();
            //You need to specify a size for your pictureBox
            S.Width=100;
            S.Height=100;

            S.Location = new System.Drawing.Point(locX, locY);
            S.Paint += new PaintEventHandler((sender, e) =>
            {
                var size = g.MeasureString(Name, btnFont);
                e.Graphics.DrawString(Name, btnFont, Brushes.Black,
                  (S.Width - size.Width) / 2,
                  (S.Height - size.Height) / 2));
            }
            return S;
         }
    }
}

Now in one of your forms

Panel1.Controls.Add(Tools.NewBtn("btn1",200,200));

or
PictureBox myButton=Tools.NewBtn(“btn1”,200,200);

I did not compile this or test it in anyway, there may well be a typo, please let me know if there is something obvious so I can edit out the errors
