Controls:

With consecutive pushing of this button you can choose: "1", delimiter of the number ",", "square root - sqrt", "n-th root - nthroot", "integral - int", "function to find roots of equations - solve". To lock any variant just stop pushing this button 1 second.
-
With consecutive pushing of this button you can choose: "number related to the button", "symbols related to this button". To lock any variant just stop pushing this button 1 second.

With consecutive pushing of this button you can choose: "plus operator", "minus operator", "multiplication operator", "division operator", "exponentiation operator", "plus/minus operator", "factorial", "vector multiplication operator". Also with this pushed button you can highlight the part of equation by using Left/Right buttons.

By "clicking" on this button program will numerically calculate equation (this means "="); by pushing button more than 0,4 sec. program will symbolically calculate equation (this means "->"). Also, if the cursor located on the right of the not defined variable or not defined function this button will create a definition operator (this means ":=" ).

Removing last character (Backspace). In the mathematical reference book this button means "Back".

Congratulations for release 0.8! Maybe it is possible to describe the solved bugs (especially those which produced calculation errors) more in detail (I mean what was the error, and why), just to increase reliance because this may be a little problem (unfortunatelly!).
But although, really nice work and keep going!!
Jakob

No problems, here is something that I remember:

Thank you for the new release. Very interested in the Portable Version!
I have a few questions:
* Were units added?
* I love the fact that you made SMATH compatible with MathCAD (I use at work) Problem is that .xmcd file-format not as well supported. Even on the MathCad collab, they request you post to .mcd file for greater audience. Personally, at work, I have set up to software to save to "MathCAD Compressed XML Document .xmcdz" In short, support for these two file formats would be appreciated
* Did you add literal subscripts? MathCad would be the period key?
Insignificant bugs in portable version.
* In the about, your date is 12/31/1999 with application components also showing 1999
* settings.INF file generated shows SMATH version .78

Thank you for the great software

Hello, ElSid.

1) Units not implemented yet;
2) XMCD supported just partially, it can't be fully parsed, because MathCad and SMath Studio has too much differences. But I allways work to increase compatibility. Regarding to .xmcdz: I'll check it;
3) No subscript yet. Will work on it later;
4) 1999: this is known bug. I just had no time to debug it. Next version, I hope, will be with right time represented;
5) Yes, I forgot to change it

Thank you.

Hi,

Would you develop SMath for Smartphone 2003, pls...
I can't install .Net Framework 2.0 on Smartphone 2003 (SP 2003 only support .Net framework 1.0).

Thank you.

Hello.

Sorry, but unfortunately this is impossible. Smartphones on Windows Mobile 2003 will never be supported.

Hello,
this is my first post. Don't expect a lot more
I am a winPenPack Team member. We deal with portable software, and I already signaled your program in our forum. Today I found the (good) news about a Portable version, so I tested it with Regshot for verify its portatility...
Unfortunately, it is still far from a real portability (the non-portable version modifies the PC configuration much less...). I think that the problem is Xenocode itself, that creates following (empty) registry keys


and creates also this folder (with all subfolders)


Did it is possibile to delete both registry keys and folder(s) on program exit? I think that these objects must exist only during program execution and can be deleted after...
Best Regards

Thank you for the detailed information. You are right, described is Xenocode's features.
Later today or tomorrow I will try to find out a way to exclude these system changes.

ZioZione, unfortunately, changing of the XSandbox location - all that I can do.

Hello,
first of all, thank you very much for your attention!
I tried your new release but it behaves as previous one:

Registry keys added:
Folder added (with all related subfolders)
I searched by myself some informations and I found an interesting link (I think is what you was talking about) here (see section related with USB device).
As you can see, it should be enough (if possible) to substitute "@APPDATALOCAL@" with "@APPDIR@" in the path you depicted above, allowing Xenocode to save everything into program folder. I don't know, indeed, how to avoid the creation of the registry keys: Xenocode should allow to use a virtual registry, but I don't know (at this moment - I never used it before, but I will search some hint - ) how to manage Xenocode own registry keys.
Hope this helps.
Best Regards
ZioZione

Congragtulations and thank you for A great and wonderful work sir!

Keep up the good work.. and thankyou for giving the software for free..
Your software helps me in some of my simple mathematics computation..

Best regards
