Thank You In Advance

Praveen as per my understanding I am writing some steps below. Please once go through below steps:

Step-(01.) Add a winform and from their property select IsMdiContainer = True.

Step-(02.) From toolbox drag & drop 1 MenuStrip control on your MDI form.

Step-(03.) Now on your MDI form add different menu items as per your requirements.

Step-(04.) Add different winforms in your application as per your requirement.

Step-(05.) Now double click on every menu items you will get code like below.

private void formNO01ToolStripMenuItem_Click(object sender, EventArgs e)

{

// You have to write some code here

}

Step-(06.) Take a static variable on your MDI form.

public static int OpenFormCount = 0;

Step-(07.) Inside all menu item click event check & show your forms as per your requirement like below.

if (OpenFormCount <= 5)

{

Form1 frm = new Form1();

frm.Show();

OpenFormCount++;

}

else

{

MessageBox.Show("Allready you have opened 5 form. If you would like to open other form then please close any one form");

}

Step-(08.) Now for your all winforms on FormClosing event decrease the "OpenFormCount" variable like below:

private void Form1_FormClosing(object sender, FormClosingEventArgs e)

{

OpenFormCount--;

}

Now I think you can do your rest jobs. Like adding panel on MDI form and LINK label.

And at the place of showing message in my code you can add your LINK label text.
