Have a look here: ManagedXLL

Try running http://dependencywalker.com/ on your XLL to see what's missing on those machines.

No problem here If it really doesn't work, simply load the .XLL as a .DLL - there is no difference!

<t>The answer depends heavily on the consuming application on the UNIX machine. If possible, try to compile your code on UNIX. This should be straightforward for "pure" C and C++ code. The equivalent of a DLL is a shared library - Google is your friend. There are solutions for DCOM on UNIX, but it m...

Automation add-ins are not available in Excel 2000 and limited in features compared to XLLs. Visual Studio Tools for office does not have support for add-in functions. See http://www.stochastix.de/ for an alternative supporting Excel 97-2003.

groberts is right, but you must enter SUM(ABS(range)) as array function returning a 1x1 array. Although not documented, most worksheet functions can be used as array functions.

use SUMIF to add positive and negative values separately

http: no. maybe an UNC path like \\MACHINE\SHARE but I haven't tried this. See "NET USE /?" on how to map a share programmatically. However, you should really consult your administrators before...

<t>You must map a network drive to do that - which might be unreliable or cause delays when included in the path. Manipulating the system's default requires Administrator permissions and has severe security implications. I wouldn't do that. Do speak with your admins if they can not provide a better ...

<t>First, is it possible to access a DLL (to be used by excel) remotely over the internet, and if it is, how do you go about doing it?You must map the DLL's folder somehow, e.g. using a file share, http(s) (install Novell's NetDrive!), etc.Second, how can the PATH environment variable be set from ex...

How could you plug C# addin in Summit , Murex that are C/C++ native software under unix without their support? Host the .NET or Mono run-time!?

AFAIK, Sourceforge tries to force email servers to follow certain policies - which your adminsitrator might have chosen not to (had the same problem once). Try to subscribe from e.g. gmail, and redirect incoming email to your cooperate account.Jens.

My tool is bigger than yours (It's always amazing that such a crappy subject can attract so many people.)

agree with Dominic, Pascal is for ....Turbo Pascal was really good for creating DOS applications and isn't such a bad language. After all, Turbo Pascal's creator, Anders Hejlsberg, is the man behind C# and you will recognize some concepts and keywords...
