In MDIParent :

Aryan.CallApplication = aa;//word.document
frmCallApplication App = new frmCallApplication();
App.MdiParent = this;
App.WindowState = FormWindowState.Maximized;
App.Show();

this code call the frmCallApplication, where i have written the code as follows:

private void frmCallApplication_Load(object sender, EventArgs e)
{

if (Aryan.CallApplication == "402000000")
{
if (axOffice.IsInstalled("Word.Document"))
{
axOffice.CreateNew("Word.Document");
}
else
{
MessageBox.Show("MSWord Not Installed, Install it First !");
}
}
}
