You could just do: 

<pre><code class="code-1 nolinks" id="code-261609">if (MessageBox.Show(&quot;This record is locked for editing in ddddd\n Do you want to open the record in view only mode&quot;, &quot;HART&quot;, MessageBoxButtons.YesNo, MessageBoxIcon.Question) == DialogResult.Yes)
{
 // ...show your other form...
 Form2 f2 = new Form2();
 f2.Show();
}
</code></pre>
</div>

<div>
No matter what, you should always dispose it out of memory. &nbsp;It may get stuck and if the garbage collection cannot reap the unused memory, you will end up with a memory leak.

Dispose of WHAT crokeefe28? 
 
The author states that when No is selected: 
 
&nbsp; &nbsp; &quot;I want the user to remain in the orginal form where the message was genertaed from&quot; 
 
Calling this.Dispose() would close the main form...probably not the desired effect! &nbsp; =\
</div>

<div>
The message box, and it should only dispose of the box itself.

Well...the code in that link is using a CUSTOM MESSAGEBOX (which is a Form). &nbsp;It is disposing of the static member: 
 
&nbsp; &nbsp; static MyMessageBox newMessageBox; 
 
Otherwise we would have a MyMessageBox instance in memory unnecessarily. 
 
In this case, we are just calling a STANDARD messagebox from a regular form. &nbsp;Calling &quot;this.Dispose&quot; in the above code would cause the calling form to close. 
 
The built in messagebox dialogs dispose of themselves...

<div>
The rest of the code is still beign executed 

<pre><code class="code-10 nolinks" id="code-262560"> MsgBoxAnswer2 = MessageBox.Show(&quot;This record is locked for editing in gggg by &quot;+checkLocks()+&quot; \n Do you want to open the record in view only mode&quot;,
 &quot;Tager&quot;, MessageBoxButtons.YesNo,
 MessageBoxIcon.Question).ToString();
 }
 if (MsgBoxAnswer2 == &quot;Yes&quot;)
 {
 button1.Enabled = false;
 
 }
 
 switch (MsgBoxAnswer2)
 {
 
 case &quot;No&quot;:
 this.Dispose();
 break;
 }
</code></pre>
</div>

<div>
...???... 
 
How about? 

<pre><code class="code-10 nolinks" id="code-262572"> DialogResult result = MessageBox.Show(&quot;This record is locked for editing in gggg by &quot;+checkLocks()+&quot; \n Do you want to open the record in view only mode&quot;, &quot;Tager&quot;, MessageBoxButtons.YesNo, MessageBoxIcon.Question);
 switch (result)
 {
 case DialogResult.Yes:
 button1.Enabled = false;
 break;
 
 default:
 this.Dispose();
 break;
 
 };
</code></pre>
