Hi Everyone,
I made some modifications to muparser that I think may interest some people. I added the possibility to include more that one equation in an expression. For instance one can create a parser object with the following
<pre>
X=A+B
Y=X+A
Z=X+Y
A =Y
</pre>
and if the values of A and B are set to 3 and 10, as a result the values for A, B, X Y and Z will be...

Switching from Unicode to "Not Set" worked like a charm. It compiled and ran fine.
Thank you for the help.

oops forgot to mention the variable declaration is in the Form Class. It is an Windows Form Application in C++.
And there was a typo last message XD I "don't" remember/know enough :) forgot the word don't.

Yeah that is the main reason I switched to Java, then VB.
I haven't programmed C++ in over 7 years and is really rusty.
When I declared the variables as normal variables the C++ wont' compile saying mixed type are not allowed. So I had to make the variables as pointers, initializing them at constructor and delete them at destruction. It is a pain but I remember/know enough about C++ to...

No, but there is a C# wrapper:

You appear to have an affinity for dynamic allocation but C++ is not C#. There is no garbage collector that will clean up for you. Nevertheless the code should compile. I suspect you are using an UNICODE so try std::wstring instead of string or disable UNICODE in the project settings.
a general example is here:

I am very very rusty with C++ and I am trying to figure out how to use DefineFun with a string variable instead of typing the actual name in.
I have
public:
mu::Parser *parser;
string *FunctionName_Ceiling;
string *FunctionName_Floor;
in my class Defintion
then later on in the constructor I have
parser = new mu::Parser();
FunctionName_Ceiling =...
