<h1>Working with memory</h1>

<p>You can inspect and change process memory.</p>

<p>The Memory view supports the same addressing as the C and C++ languages. You can address memory using expressions
such as:</p>

<ul>
 <li><samp>0x0847d3c</samp></li>
 <li><samp>(&amp;y)+1024</samp></li>
 <li><samp>*ptr</samp></li>
</ul>

<p> You can configure your output to
display hexadecimal, ascii and/or signed/unsigned decimal. You can also set the
size of the rendering columns. You can configure each memory monitor renderings
independently.</p>

<p> You can customize the Memory view to colors and fonts displayed.  </p>

<p>To monitor process memory:</p>
<ol>
<li> In the Debug view, select a debug session. Selecting a thread or stack frame automatically
selects the associated session.</li>

<li> Select <strong>"Add Memory Monitor"</strong> in the context menu of the Memory Monitors pane.
The <strong>"Memory Monitor"</strong> dialog appears.</li>

<li> Type the address or expression that specifies the memory section you want to monitor and
press <strong>"OK"</strong>. The monitor appears in the monitor list and the Memory Renderings
pane displays the contents of memory locations beginning at the specified address.</li>

</ol>
<p>To view memory in a different rendering: </p>
<ol>
<li> Select <strong>"Add Rendering"</strong> in the context menu of the Memory Renderings pane.
The <strong>"Add Memory Rendering"</strong> dialog appears.</li>

<li> Select renderings from the list and press <strong>"OK"</strong>.</li>
</ol>
<p>To change process memory:</p>

<p><strong>Warning:</strong>
Changing process memory can cause a program to crash.</p>

<ol>
 <li> In the Debug view, select a debug session. Selecting a thread or stack frame automatically
     selects the associated session.</li>
 <li> In the Memory Monitors pane, add a new monitor or select an existing monitor.</li>
 <li> In the Memory Renderings pane add a new rendering or select an existing one.  </li>
 <li> Type a new value for memory.  </li>
</ol>
