Saving file without dialog
<p>I have looked everywhere and can't find the thing I am looking for. What I want is code for the saveToolStripMenuItem_Click event handler on the "Save" menu (NOT "Save As...") and have my app check to see if:</p>

<ol>
<li><p>The current file has already been saved, therefore already has a filename.</p></li>
<li><p>The current file has been modified since being opened.</p></li>
<li><p>Overwrite (or append, as needed) the existing file without bringing up the "Save As" dialog.</p></li>
<li><p>Brings up the "Save As..." menu if the file does not already exist.</p></li>
</ol>

<p>My "Save As..." menu already works properly. Everything I have found tells me how to create a "Save As.." dialog, which I already know. Every sample program I have downloaded does not have this functionality.</p>

<p>Any help would be appreciated.</p>
