<p>I am trying to call a COM object from PHP using the COM interop extension. One function requires an OLE_COLOR as an argument? Is there any way to pass this kind of value from PHP?</p>
<p>I have tried passing a simple integer value with no success.</p>

$myComObject->Myfunction( myVar1, myVar2, 'my string var');

<p>I just changed my nozzle on my Anet A8 after it was fully used up. When I started printing with my new 0.4 mm nozzle (same as before) my <a href="https://imgur.com/a/2x42LTB" rel="nofollow noreferrer">extrusion</a> was VERY bad and inconsistent, even so bad I couldn't continue printing because it would pull the... | <p>Your good extrusion look also a little bad , and the bad extrusion looks like a big feeding problem. for this you need:</p>

As I assumed that there were no other changes during the nozzle exchange process, then there is a risk of a gap inside throat and nozzle that just builds up and blocks the extrusion.</p>

<p>I am using the <code>MonthCalendar</code> controls in a Windows Forms application.
I want to gray out the dates older than the control's MinDate (or give the user some visual clue about which dates are not valid for selection).
The control has no property for getting the behaviour I expect.
I have tried the <code>Ul... | <p>The MonthControl seems to already do what you're looking for. Setting the minDate property removes the invalid days/years from the calendar so they can't be selected. Works in .NET 2.0 and 3.5.</p>
