//Use DLLImport for user32.dll

static extern void FlashWindow(IntPtr a, bool b);
//IntPtr structure:
//It is used to represent a pointer or a handle.

//call the function FlashWindow() passing the Handle property of the
//window to be 'flashed' and boolean value set to true.
void dd(Form w)
FlashWindow(w.Handle, true);
private void Form5_Load(object sender, EventArgs e)
//initialize w variable
Form k = this;


//Output:the form caption bar will blink once. To keep it continuously
//blnking , use a Timer.
