Hi,

thanks a lot for your posting and sorry for the stupid question but how can I install it.
I have copied the 2 .dll under the plugin dir but when SmathStudio starts I receive several error messages and the plugin is not loaded.

Thanks in advance for your help and your efforts to improve smath.

The same question,

I also do not know how to make this plugin to work and which one of the dll's from this archive to use and how.
I assumed that I have to copy everything under "plugins" folder in this archive into "plugins" folder of SMath. As Francesco mentioned, severeal error boxes appeared. This is obviously wrong regarding the dates (from 2009) of some of the approprriate dll's (or not?).
Here is one of the error boxes:

Is there maybe some mess with Mathcad's system of user made functions via dll's?

Regards,
Radovan

Try these dlls: mcadefi_20101123.7z
I don't know where a problem. All works for me.

mcadefi.dll and mcaduser.dll must be in the "\plugins\" folder. Path "plugins\userefi\" must exists.
SMath Studio version: 0.89.8 (03 October 2010)

It is working now Biggrinancing:

Thank you uni very much Thank you

BTW, I hope that something could be done in order the new user functions inserted via plugins could have their place under Insert|Function Category. At the moment they can be seen only in the "all" category and via Dynamic Assistance.

Radovan

Mathcad strings are not supported yet and error tables too.

Ah yes, you are right- forgot to mention. I've looked there first to see how many functions the plugin consists of.

Thank you for your efforts. I appreciate it very much.

Thank you, Francesco.

Check new version on your system: mcadefi_20101124.7z
This one completely supports the User EFI interface, with strings and error messages.

I have tried to load the Mathcad EFI plugins for SMath Studio 0.89(build 8) unsuccessfully.

I copied the files "mcadefi.dll" and "mcaduser.dll", and the folder "userefi" (containing the files "bmqcad.dll", DIGAMMA.DLL", "KRONECKR.DLL", and "mathlib.dll"Wink into my SMath Studio directory, namely: "C:\Program Files(x86)\SMath\SMath Studio\plugins".

I keep getting two messages indicating that it couldn't load or assembly "mcaduser.dll".

I am using a Windows Vista Ulimate in a 64-bit Toshiba Satellite laptop.

Any ideas on what I could be doing wrong?

Try to put files (just mcaduser.dll and "userefi\*.*" ) on another path:
"C:\Program Files\SMath\SMath Studio\plugins"

P.S. I am afraid that for a 64-bit platform it will be necessary to recompile the project.

Hmm... Uni could you explain why Avira Virus Lab detects file "bqmcad.dll" as Trojan???


I used online scaner as well: http://virscan.org/repor...d89b784c6534edfd326.html
So only 4 on 37 scanners detect it as something dangerous.
Dry I'm almost sure that is OK but ... maybe you can put some light on it Uni.

I took this file from here:
http://karataev.nm.ru/bqmcad/bqmcad.zip

The author is Evgenie Karatayev (Ekarataev@mail.ru). I don't know why scanners think so.
Here the source code of library: http://karataev.nm.ru/bqmcad/bqmcadsrc.zip
Page: http://karataev.nm.ru/bqmcad/

Possibly such effect gives a splash window:
Code:

void ShowScreen( void)
{
   if( Show)
   {
      // show only copyright message
      MessageBox( 0, strMessage, strCaption, MB_ICONINFORMATION | MB_OK);
      Show = 0;
   }
   return;
};


Anyway you can compile your own library.

have anyone had success with this plugin in Linux? The plugin is disabled and I'm getting an error report when starting SMath:

An exception was thrown by the type initializer for <Module>

And ideas?

It uses an unmanaged code which probably isn't used in Mono. SMath Studio is completely written on .NET platform and Mathcad plugins aren't, mcadefi.dll - the intermediary between managed (.Net, SMath Studio) and unmanaged (Win32API, Mathcad UserEFI interface) code in Windows. Most likely in Linux it will never work.

This plugin only for Windows (like Mathcad).

Hello,

I've noted that Mathcad EFI plugin has its own round(1) function. SMath has round(2). In spite of that the both functions have the same name but different numbers of arguments, when the EFI plugin is active then we can not use round(2). Here is a simple example:

EFI plufin enabled:
c←80/9
c=8.8889
round(c)=9
round(c,3)=9

EFI plugin disabled:
round(c,3)=8.889

Regards,
Radovan

This function from Mathematical library for MathCad v1.2 (Giuseppe Borzì ) which is in the userefi/mathlib.dll file. You can delete mathlib.dll and function round() will disappear without plug-in switch-off. The example with function is given in the Mathlib.pdf (page 3).
