This is a simple example of using Win32 api in .NET. I'll use the FlashWindow() API from user32.dll so as to make the window go flashing and get attention.
Take a simple Windows form and add a button to it. Add a reference to System.Runtime.InteropServices namespace. And heres the code.
// --------- code -----------
[DllImport("user32")]
public static extern int FlashWindow(int hWnd, int bInvert);
public
partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}
private void button1_Click(object sender, EventArgs e)
{
FlashWindow(this.Handle.ToInt32(), 1);
}
} // -------- code ends
This was nice and simple for the start.

Thinking of where to start from with millions of topics in mind. I will dedicate this blog to unmanaged code. As a .NET programmer, I will be illustrating use of Win32 native code in managed .NET code.
Right form the start, I was really interested in exploring the Interop framework of .NET.
So this blog will be a mix of both, unmanged in managed world.
