<p>I would like to keep the overhead at a minimum. Right now I have:</p>

<pre><code>// Launch a Message Box with advice to the user
DialogResult result = MessageBox::Show("This may take awhile, do you wish to continue?", "Warning", MessageBoxButtons::YesNo, MessageBoxIcon::Exclamation);

// The test will only be launched if the user has selected Yes on the Message Box
if(result == DialogResult::Yes)
{
    // Execute code
}
</code></pre>

<p>Unfortunately my client would prefer "Continue" and "Cancel" in place of the default "Yes" and "No" button text. It seems like there should be an easy way to do this.</p>

You can use "OK" and "Cancel"
By substituting
```
MessageBoxButtons::YesNo
```
with
```
MessageBoxButtons::OKCancel
```
MessageBoxButtons Enum
Short of that you would have to create a new form, as I don't believe the Enum can be extended.
