Hi everyone,I was trying to compile the Quantlib Addin on my laptop (OS: Windows XP SP2; Visual Studio 2005 express) and i just got a funny problem:------ Build started: Project: AddinExcelStatic, Configuration: Debug Win32 ------

it just looks like I have some problems with the linker. Having a look around on internet I found out it might be related to a problem importing a c function in a c++ project without using the 'extern "C" ' statement ( http://blogs.msdn.com/vsdteam/archive/2005/11/20/495123.aspx). Is it correct? if it is so, where do I have to modify the code?

Hi, I complied both latest versions of ObjectHandler and QuantlibAddin, but could not load up any *.xll files due to error msg stating that the xll files are NOT of Excel add-in format.

Similar problem here, just that I'm using MS VC++ 2005 Express (8) and MS Excel (Office) 2003.

1. http://www.planatechsolutions.com/xlpfaq/Q0011.htm essentially open your xll in visual studio tool "depends" and see if any dll xll depends on is missing. I suspect log4cxx , oh
dll
may not be in the path. If you do not have depends, go to www.dependencywalker.com. 2. I am hoping that you are not mixing managed C++ and unmanaged C++
as
string in managed C++ are treating differently. Most likely you
are
not doing this. 3. If point 1 does not rescue you, you may be mixing debug/release libraries, just check that you are not doing this. 4. Using DumpBin /Exports should list the DLLs bound statically to
your
code. You need to ensure they are in your path, and not just lying around the target machine.

2) Using automation instead of the C API

XLL technology is getting deprecated. Most of your efforts are likely to be lost in coming
years. For a long time it seemed evident that MS were trying to steer developers away from the API toward newer replacements - VBA/COM/.NET. Many people continue to use the API because for certain tasks it is orders of magnitude faster than the newer alternatives. And now it seems that MS have given up on their attempts to deprecate the API, apparently Excel 2007 will include enhancements to the API: http://blogs.msdn.com/excel/archive/2006/01/03/508985.aspx Regards, Eric CONFIDENTIAL NOTE: The information contained in this email is intended only for the use of the individual or entity named above and may contain information that is privileged, confidential and exempt from disclosure under applicable law.
