Introduction
Not much to say but to create this tool to capture any part and size of the screen you want, is very simple and can be accomplish in a few minutes.

Creating the application
1 - Create a new windows application project in Visual Studion, for this example I called it ScreeCapture, add a button and an OpenFileDialogue to the form.

2 - Add these using to the namespace

Code: Select all

using System;
using System.Drawing;
using System.Drawing.Imaging;
using System.Threading;
using System.Windows.Forms;
3 - Add variable to store output file name

Code: Select all

private string strFilename;
4 - Add Property for storing and retrieving output file name

Code: Select all

public string filename
        {
            get { return strFilename; }
            set { strFilename = value; }
        }
5 - Now that we declare all the needed variables go to the form design and double click the button and this will create Click event of the button1 control.
Now lets define the proprety for the OpenFileDialogue
Add this in the button event

Code: Select all

saveFileDialog1.Filter = 
 "JPG File (*.jpg)|*.jpg|BMP File (*.bmp)|*.bmp|PNG File (*.png)|*.png|GIF File(*.gif)|*.gif|Tiff File (*.tif)|*.tif";

saveFileDialog1.FilterIndex = 1;
saveFileDialog1.RestoreDirectory = true;
Now lets add a check if user clicked OK button and Get the file name and store it in are variable

Code: Select all

if (saveFileDialog1.ShowDialog() != DialogResult.Cancel)
            {
                // Get the filename and store it
                filename = saveFileDialog1.FileName;
            }
            else // If Cancel was selectedreturn
                return;
6 - Now that we have the file name the user want to save the capture lets create the graphic to hold the capture.
Add

Code: Select all

// Creating new bitmap with the size of the form                    
Bitmap bmp = new Bitmap(this.Width, this.Height, PixelFormat.Format32bppArgb);

// Creating graphic object from the image
Graphics gr = Graphics.FromImage(bmp);
7 - Now lets take the snapshot

Code: Select all

gr.CopyFromScreen(this.Left, this.Top, 0, 0, this.Size, CopyPixelOperation.SourceCopy);
8 - Now the only thing left to do is to save the capture under the given file name

Code: Select all

switch (saveFileDialog1.FilterIndex)
                    {
                        case 1:
                            bmp.Save(filename, ImageFormat.Jpeg);
                            break;
                        case 2:
                            bmp.Save(filename, ImageFormat.Png);
                            break;
                        case 3:
                            bmp.Save(filename, ImageFormat.Bmp);
                            break;
                        case 4:
                            bmp.Save(filename, ImageFormat.Gif);
                            break;
                        case 5:
                            bmp.Save(filename, ImageFormat.Tiff);
                            break;

                    }
