A  The main GUI thread will run endlessly on the call to Application Run  so your while loop will never be reached  B  You would never want to have an endless loop like that  the while true  loop  - it would simply freeze the thread  Not really sure what you re trying to achieve there   I would create and show the  main   initial  form in the Main method  as Visual Studio does for you by default   Then in your button handler  create the other form and show it as well as hiding the main form  not closing it   Then  ensure that the main form is shown again when that form is closed via an event  Example   public partial class Form1   Form     public Form1           InitializeComponent               private void button1 Click object sender  EventArgs e                Form2 otherForm   new Form2        otherForm FormClosed    new FormClosedEventHandler otherForm FormClosed       this Hide        otherForm Show                 void otherForm FormClosed object sender  FormClosedEventArgs e          this Show

Anything after Application Run    will only be executed when the main form closes   What you could do is handle the VisibleChanged event as follows   static Form1 form1  static Form2 form2   static void Main          Application EnableVisualStyles        Application SetCompatibleTextRenderingDefault false       form2   new Form2        form1   new Form1        form2 Hide        form1 VisibleChanged    OnForm1Changed      Application Run form1       static void OnForm1Changed  object sender  EventArgs args         if    form1 Visible                 form2 Show

i believe the following code will only run after form1 is closed   while  true                if  form1 Visible    false              form2 Show            Why not start your form2 from form1 instead   Form2 form2   new Form2     private void button1 Click 1 object sender  EventArgs e                if  richTextBox1 Text    null                        form1 Visible false              form2 Show                       else MessageBox Show  Insert Attributes First

To link to a form you need    Form2 form2   new Form2            form2 show     this hide      then hide the previous form

The While statement will not execute until after form1 is closed - as it is outside the main message loop   Remove it and change the first bit of code to   private void button1 Click 1 object sender  EventArgs e            if  richTextBox1 Text    null                    this Visible false          Form2 form2   new Form2            form2 show                else MessageBox Show  Insert Attributes First             This is not the best way to achieve what you are looking to do though   Instead consider the Wizard design pattern   Alternatively you could implement a custom ApplicationContext that handles the lifetime of both forms   An example to implement a splash screen is here  which should set you on the right path   http   www codeproject com KB cs applicationcontextsplash aspx display Print
