hi every one
please help me for this problem

This is a specific Maple 2016 question: I find that plots no longer remember their attributes (like size on the screen) upon re-execution of a worksheet, even though I have set the appropriate flag in the Interface pane of the preferences.

Can someone confirm this; or am I just being dense? Is this an OS X issue? An El Capitan issue?? Maple 2015 on Yosemite behaves as expected.

Maple 2016.1 on Mac OS X 10.11.5.

Thanks,

M.D.

hi .please help me for this error

i work on Maple 18 and recently maple standard worksheet interface not run properly.

i already have  uninstall and again i have same problems

I try to connect Maple with C# by using OpenMaple at http://www.mapleprimes.com/posts/38048-Using-OpenMaple-With-C

But OpenMaple just excuted in x64 mode, I want to excute OpenMaple in "Any CPU" mode. How can I do this?

P/s: I'm using Windows 7 Ultimate x64 and Visual Studio Ultimate 2013.

if i install maple 2015 in amazon cloud, activate with my license

and i do not use amazon after several trial, 

will the license be used and can not activate in future if i use amazon cloud again in future?

any command or configure needed when using large amount memory such as 100GB memory?

hi everyone..i would like to ask,why do we need to type in (101-100λ) in our maple program..why do we need the continuation..thanks in advance for answering..

Hi 

Sometimes this happen to me.

why ?  and how can I fix it?

DEAR SIR,

PLEASE HELP ME WITH THAT QUESTION

I have a gensym routine (gensym = generate symbol) which appends Chinese characters to some base symbols to create 'new' symbols.  This works well on Windows, Mac and tty maple.  But I get all square boxes in the linux GUI.

I know the fonts exist as, on the same machine, it works in tty.  But I have no idea how to tell the GUI to go and use those fonts.  Nor why it isn't.

Amusingly, if I try to paste something from the GUI as MapleMath here on Primes, in the 'paste' box, it shows just fine, but then it says it is invalid Maple.

For example, from the GUI I see

but the same thing in TTY is

(x三0不 + x三1下)^(-M)

and I just did cut-and-paste of the same thing.  By this I mean that I took that output with boxes above, put it into a terminal window, re-copied that, pasted it in here, and voila!

So clearly the issue is with the GUI, and only on linux (Ubuntu 16.04).

I watched a webinar training:   Maple Training for Engineers, Researchers, and Scientists.

The file demonstrated topics and used collapsible regions with a colored band across the document and a + / - sign on the left to open/close the section or region.  Different than the document gray down arrow.

I have searched all the documentation and can not find how to do this.   I have done this in other programs like MathCAD to close and lock a region from viewing or editing of specific formulas.

Any help always appreciated.

Regards,

Bill

I'm currently working on building a Grid Layout for a project, and I'm having trouble coding in the RunWindow and GetFile elements into buttons under the grid layout. I've gone through the overviews and examples for them, but had no luck. I'm using Maple 2016.1 for OS X.

Additionally, the structure of the code is slightly different as to how many of the example worksheets structure their Grid Layout code, since the code originated from a Maplet Builder file. I.e. in the example worksheets they would follow as:

maplet := Maplet('onstartup' = 'Action1', 'reference' = 'Maplet1',
         BoxLayout('background' = "#D6D3CE", 'border' = 'false', 'halign' = 'center', 'inset' = '5', 'reference' = 'BoxLayout1', 'valign' = 'center', 'vertical' = 'false', 'visible' = 'true',
                       BoxColumn( BoxCell('hscroll' = 'never', 'value' = 'Button1', 'vscroll' = 'never'),
         GridLayout('background' = "#D6D3CE", 'border' = 'false','halign'='center','inset'='5', 'reference' = 'GridLayout1', 'valign' = 'center', 'visible' = 'true',
                   GridRow('valign' = 'top', GridCell('height' = '1', 'hscroll' = 'never', 'value' = 'BoxLayout1', 'vscroll' = 'never', 'width' = '1' ))),
         Window('layout'= 'GridLayout1', 'reference' = 'W1', 'resizable' = 'true', 'title' = "Maplet"),
          Action('reference' = 'Action1', RunWindow('window'= 'W1'))

However the structure for the code I am working with has action at the very start of the code, follwed by the the code for the buttons then layouts/window.  E.g. (the code has been shortened)

with (Maplets[Elements]):
maplet :=
Maplet('onstartup'='Action1','reference'='Maplet1',
Action('reference'='clickButton1'),
Action('reference'='clickButton9',
Evaluate('function'='plot3d(x^2*cos(y),x = -1 .. 1,y = -2*Pi .. 2*Pi)','target'='Plotter1','waitforresult'='true')),
Action('reference'='clickButton11'),
Action('reference'='clickButton12'),
Action('reference'='clickButton10'),
Button('background'="#D6D3CE",'caption'="Insert Molecular Geometry",'enabled'='true','foreground'="#000000",'onclick'='clickButton1','reference'='Button1','visible'='true'),

....

BoxLayout('background'="#D6D3CE",'border'='false','halign'='center','inset'='5','reference'='BoxLayout1','valign'='center','vertical'='false','visible'='true',
BoxColumn(
BoxCell('hscroll'='never','value'='Button1','vscroll'='never'),
BoxCell('hscroll'='never','value'='BoxLayout2','vscroll'='never'),
BoxCell('hscroll'='never','value'='BoxLayout3','vscroll'='never'),
BoxCell('hscroll'='never','value'='BoxLayout9','vscroll'='never'),
BoxCell('hscroll'='never','value'='BoxLayout14','vscroll'='never')),
BoxColumn(
BoxCell('hscroll'='never','value'='Label3','vscroll'='never'),
BoxCell('hscroll'='never','value'='Plotter1','vscroll'='never'),
BoxCell('hscroll'='never','value'='Slider1','vscroll'='never'))),
GridLayout('background'="#D6D3CE",'border'='false','halign'='center','inset'='5','reference'='GridLayout1','valign'='center','visible'='true',
GridRow('valign'='top',
GridCell('height'='1','hscroll'='never','value'='BoxLayout1','vscroll'='never','width'='1'))),
Window('layout'='GridLayout1','reference'='Window1','resizable'='true','title'="Maplet"),
Action('reference'='Action1',
RunWindow('window'='Window1'))):

Maplets[Display](maplet);

If anyone would be able to provide an example of code or some guidance I could follow that would be greatly appreciated! 

MAPLE 15 on Windows 10

I have a file on which I can no longer open. This happened after my computer made me long on again after being gone for a little while. Maple was not running when I got back on. This is not unusal and I just clinck on the file and restart.

This time this did not work.

It comes up with a message asking me to select an input mode. Whatever I select even 'Plain text' it just hangs.

I'd send you an image, but I don't see how to do it. The button provide only allows for something with  url and the snip I made is on my desktop.

I need to get thiis worksheet back. I've put a lot of effort into it.
