    <p>i discovered today that Windows 7 comes with a very impressive MathPanel utility, for performing handwriting recognition of equations:</p> <p><img src="https://i.stack.imgur.com/7nlvp.png" alt="enter image description here"></p> <p>Which is fine. (Here i've entered the formula for the part of the sRGB color space gamma conversion)</p> <p>But now i don't seem to be able to <em>do</em> anything with it.</p> <p>There is an <strong>Insert</strong> button. i would assume that clicking <strong>Insert</strong> would insert it into the application that is active behind it (much like the On-Screen Keyboard works):</p> <p><img src="https://i.stack.imgur.com/jY1XX.png" alt="enter image description here"></p> <p>Except i assume it would operate as a Paste operation.</p> <p>i can find no information in the help on what is required by an application to make it work. There is no mention of any special API some software must support. </p> <p>Nor can i find any information on MSDN about what special API is required to accept the insertion of an equation.</p> <p>What API, registration, callback, listener, message, COM Object do i have to implement so that i will receive MathPanel input?</p> <p>The only reason i mention <strong>MathML</strong> is because an answer on <a href="https://superuser.com/a/42146/8169">SuperUser mentioned MathML</a>:</p> <blockquote> <p>Theoretically, any app that supports <strong>MathML</strong> (Mathematical Markup Language) can be used with the Windows 7 Math Input Panel. The Math Input Panel <strong>only works</strong> with programs that support MathML. Here are a few such apps: StarOffice, OpenOffice, Opera and Maple.</p> </blockquote> <p>Well how do i make <em>my</em> program support MathML?</p> <p>As far as i know MathML is a markup language; not a Windows API. It would be like saying, "How do i make my program support HTML?" Html is text, and you can paste it anywhere.</p> <p>MathPad refuses to paste unless i "support" MathML?</p> <hr> <p><strong>Update</strong></p> <p>Inspecting the <code>IDataObject</code> on the clipboard after clicking <strong>Insert</strong>, i see two formats available (neither of which are text, which explains why i do not get any markup):</p> <p>Format 1: </p> <pre><code> CLIPFORMAT cfFormat: "MathML Presentation" (49839) PDVTargetDevice ptd: 0x00000000 DWORD dwAspect: DVASPECT_CONTENT DWORD lindex: -1 DWORD tymed: 1 (TYMED_HGLOBAL) </code></pre> <p>Format 2: </p> <pre><code> CLIPFORMAT cfFormat:"MathML" (49838) PDVTargetDevice ptd: 0x00000000 DWORD dwAspect: DVASPECT_CONTENT DWORD lindex: -1 DWORD tymed: 1 (TYMED_HGLOBAL) </code></pre> <p>So at least now i have some clipboard formats:</p> <ul> <li>"MathML Presentation"</li> <li>"MathML"</li> </ul> <p>i still cannot find anything on MSDN about either clipboard format.</p>

    1. COLooks like is the responsibility of the app to register for clipboard updates then pull off "MathML" entries as XML; http://dpcarlisle.blogspot.com/2010/01/mathml-on-clipboard.html

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
