Capturing screenshot using shortcut keys

Question

Hi there.
I have this application that basically captures a screenshot
of the active window. In essence, if I double-click the application from
its folder, it will capture a screenshot of the folder. If I create a shortcut
to the application and double-click the shortcut it still Works perfectly.
However, if I use shortcut keys to start the shortcut, it captures the process
bar(start menu, systray etc.) and not the "active folder". I use
windows 8, Visual Studio 2012. I have tried to build both in .net framework 3,5
and 4,5. I hope that anyone can help me, my code is below: using System;
using System.Data;
using System.Diagnostics;
using System.Drawing;
using System.Runtime.InteropServices;
using System.Threading;
using System.Windows.Forms;
namespace HardCopy
{
public partial class HardCopy : Form
{
Bitmap screenShotBMP;
Rectangle rect = new Rectangle ();
[ DllImport ( "user32.dll" )]
static extern IntPtr GetForegroundWindow();
[ DllImport ( "user32.dll" , SetLastError = true )]
static extern bool GetWindowRect( IntPtr hWnd, out Rectangle lpRect);
[ StructLayout ( LayoutKind .Sequential)]
public struct RECT
{
public int Left;
public int Top;
public int Right;
public int Bottom;
}
public HardCopy()
{
InitializeComponent();
}
private void Form1_Load( object sender, EventArgs e)
{
this .Hide();
Thread .Sleep(200);
GetWindowRect(GetForegroundWindow(), out rect);
screenShotBMP = new Bitmap (rect.Width - rect.X, rect.Height - rect.Y);
using ( Graphics gr = Graphics .FromImage(screenShotBMP))
{
gr.CopyFromScreen(rect.Location, Point .Empty, rect.Size);
}
pictureBox1.Image = screenShotBMP;
this .Show();
}
}
}

have you try something like this.
void takingscreenshot(int savename)
{
string s2 = savename.ToString();
Rectangle bounds = this.Bounds;
using (Bitmap bmpScreenCapture = new Bitmap(Screen.PrimaryScreen.Bounds.Width,         Screen.PrimaryScreen.Bounds.Height))
{
using (Graphics g = Graphics.FromImage(bmpScreenCapture))
{
g.CopyFromScreen(Screen.PrimaryScreen.Bounds.X,
Screen.PrimaryScreen.Bounds.Y,
0, 0,
bmpScreenCapture.Size,
CopyPixelOperation.SourceCopy);
}
bmpScreenCapture.Save("D://" + s2 + ".jpg",         System.Drawing.Imaging.ImageFormat.Jpeg);
}
}
