Removing the Title bar of external application using c#
<p>My application starts up another application. whereby, i want to remove the title bar of the application which is started using c#.</p>

<p>What is the feasibility and how ?</p>

<p><strong>After all comments, i got some idea to implement. The below code works fine :</strong></p>

<p>//Finds a window by class name
    [DllImport("USER32.DLL")]
    public static extern IntPtr FindWindow(string lpClassName, string lpWindowName);</p>

<pre><code>//Sets a window to be a child window of another window
[DllImport("USER32.DLL")]
public static extern IntPtr SetParent(IntPtr hWndChild, IntPtr hWndNewParent);

//Sets window attributes
[DllImport("USER32.DLL")]
public static extern int SetWindowLong(IntPtr hWnd, int nIndex, int dwNewLong);

//Gets window attributes
[DllImport("USER32.DLL")]
public static extern int GetWindowLong(IntPtr hWnd, int nIndex);

[DllImport("user32.dll", EntryPoint = "FindWindow", SetLastError = true)]
static extern IntPtr FindWindowByCaption(IntPtr ZeroOnly, string lpWindowName);


//assorted constants needed
public static int GWL_STYLE = -16;
public static int WS_CHILD = 0x40000000; //child window
public static int WS_BORDER = 0x00800000; //window with border
public static int WS_DLGFRAME = 0x00400000; //window with double border but no title
public static int WS_CAPTION = WS_BORDER | WS_DLGFRAME; //window with a title bar

public void WindowsReStyle()
{
    Process[] Procs = Process.GetProcesses();
    foreach (Process proc in Procs)
    {
        if (proc.ProcessName.StartsWith("notepad"))
        {
            IntPtr pFoundWindow = proc.MainWindowHandle;
            int style = GetWindowLong(pFoundWindow, GWL_STYLE);
            SetWindowLong(pFoundWindow, GWL_STYLE, (style &amp; ~WS_CAPTION));
        }
    }
}
</code></pre>
