Hi Qb64pe community

I'm in trouble with a fine couple of QB64 keywords:  _MousemovementX & _MousemovementY

I think that the issue is raising from my bad code or bad knowledge about these two useful keywords...

here the first example taken from the wiki
mousemovementX wiki
mousemovementY wiki

This question pertains to my work on the hardware acceleration lesson in the tutorial.

According to the Wiki _PUTIMAGE should be allowed to use hardware images as either the source or destination. However this is not working for me. Please take a look at the sample code I included below. Am I missing something obvious or does the Wiki need updating?

I have never taken advantage of the Calendar. I see where there would be 2 different types - a public calendar and a private calendar. Was there a particular use intended for the public calendar? Also, on the private calendar, what features are available like color, events v's tasks, personal notifications, can I add photos or documents etc I didn't see any info on the calendar in the wiki, so I apologize if there is a tutorial on it that I missed. thanks

I've been trying to load a font from string memory, like @a740g did HERE, but none of my font string data will work like a740g code does.  i must not be doing it right.  Here's what I'm doing.

I'm first loading the entire .otf font file data into a string named fontdata$.  Then I try to load the font from fontdata$ memory like this.

myfont& = _LoadFont(fontdata$, 32, "memory")
_Font myfont&

Thanks for any help....

Saw this on Discord.  It is ported from a SpecBas program by ZXDunny and is another example of how math can be beautiful:



Screensaver Mode

When I try to print several lines of text, all indented to the same tab point (tab14), the lines are separated by a blank line.
Wiki says "Column tab prints may not always move 9 spaces past the center of the screen. Some may move text to next row.", which seems a bit "iffy". 
Is there a firm rule that applies here, or must I resort to a new Locate command? 

I'm working on the hardware acceleration tutorial lesson.

According to the Wiki _DISPLAYORDER has the following default surface order:

_DISPLAYORDER _SOFTWARE, _HARDWARE, _GLRENDER, _HARDWARE1

_SOFTWARE - I understand
_HARDWARE - I understand
_GLRENDER - I sort of understand
_HARDWARE1 - What is this?

Where does _HARDWARE1 come into play and how would I utilize it?

Also, the Wiki points out that _DISPLAYORDER can be used as:

_DISPLAYORDER [{_SOFTWARE|_HARDWARE|_HARDWARE1|_GLRENDER}][, ...][, ...][, ...][, ...] 

Does this somehow mean that the four surfaces above can be listed and used more than once? If so, how the heck does that work?

elcircle is a pretty quick subroutine to draw filled ellipses (and circles) that doesn't have the problems using Paint does. It's not a fast as fcircle but it's speedy and it can do ellipses.
