<p class="MsoNormal"><span style="color:#1F497D">I’ve PythonEngine.SetStandardOutput to an instance of a MemoryStream, and then created a StreamReader off of that MemoryStream.<o:p></o:p></span></p>

<p class="MsoNormal"><span style="color:#1F497D">When I execute Python code with ExecuteToConsole, I get output in my MemoryStream (I can see it by looking in the buffer in the debugger), but my StreamReader doesn’t believe it has data from the MemoryStream

<p class="MsoNormal">Hello,<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I’ve been enjoying using IronPython. <o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I’m now going to embed it in my C# WinForms application to provide a way for users to perform simple ad-hoc scripting. Unfortunately this has been less easy than I thought it would be!<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I’ve built a subclass of TextBox that I can use to display and input the text coming to/from my user. Now I just need to connect it to a PythonEngine.
<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">In the article at <a href="http://blogs.msdn.com/jmstall/archive/2005/09/01/Howto_embed_ironpython.aspx">
http://blogs.msdn.com/jmstall/archive/2005/09/01/Howto_embed_ironpython.aspx</a>, one gets the impression that a PythonEngine has a MyConsole property where one can connect an IConsole. Perfect! Unfortunately, that’s not the case on my 1.1 build.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Digging through the source I find that this stuff exists on IronPythonConsole, but that class appears to be designed for use statically.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Before I go to the trouble of ripping apart IronPythonConsole and likely reinventing the wheel, is there something I’m missing here?<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Thanks,<o:p></o:p></p>
