xll

I wrote a very simple xll file in VC++ 2010, and the Excel I am using is Excel 2007. The library contains only one function: extern "C" LPXLOPER12 WINAPI tsMkErr() { static XLOPER12 x; x.xltype = xltypeErr; x.val.err = xlerrNull; return &x; } and the necessary xlAutoOpen function. I compiled and dll file, change the name to xll, and double click it to open in Excel. Everything works just as I expected. However, if I am trying to open this file on another PC, the Excel just keeps telling me that: The file you are trying to open, '.xll', is in a different format than specified by the file

I am just discovering the world of programming XLLs for Excel using XLW under Visual C++ 2010 and everything has been smooth so far using the template provided with the XLW package, I have a few questions: I found out that I can register an XLL by double-clicking it. What other ways are there, especially from VBA or the Excel menu? How can I unregister an XLL, both via the Excel GUI and VBA? I assume this has to be done each time I rebuild the Xll under Visual Studio. Does Excel 2010 64-bit require XLLs compiled and linked for 64-bit? Thanks, Steve I usually use below as I have to loan/unload

I have no idea how to handle XLOPER type variable in VBA. There are plenty of web pages explaining the relationship between Xloper variable , c++ DLL and XLL add-in, however i need to write c++ function in a dll returning a xloper directly to VBA without XLL framework. (No need of User Defined Function since functions from the dll will be called by the VBA code - not by Excel users). Indeed i'm coding a Excel VSTO and i need to call c++ code from it. I found that xloper variable are very useful for XLL so i would like to use this variable type in VBA/VB.Net directly. So is it possible? my

I have developed a excel UDF. One of the UDF parameters has known possible values (A, B, C). So instead of asking all my users to find out what the possible values are I want to provide a option1 (hyperlink) in excel function wizard just like the Bloomberg's BDH function as shown in the screenshot. I know I have to somehow hook upto win32 api and override the call/window when the function wizard is invoked. When I look into SPY++ I see that there is a insert function window and function arguments window . I have broken down the task at hand into 4 sub tasks: Subclass the window “Function

I'm trying to write an array constructor for Excel as a worksheet function using the C API. Goal: =array_cons(1, 2, 3) => {1, 2, 3} However, I am not initializing the XLOPER12 correctly. In Excel, my function currently returns #NUM . I am taking the argument list and packing it into a vargs array via macros then trying to return the part of the array that was supplied. #include <windows.h> #include <xlcall.h> #include <framewrk.h> #include <boost/preprocessor.hpp> #define VARG_COUNT 250 #define VARG_FORMAT(Z, A, B) B##A, #define VARG_DEF_LIST(N) BOOST_PP_REPEAT(N, VARG_FORMAT, LPXLOPER12 varg)

I have a few mathematical simulations in unmanaged C++ and now I need to integrate them with Excel (so that it is possible to call the functions from Excel and get the values back). I don't want to use any VBA, so I guess I have to implement an XLL addin. I would like to use as few third party additional frameworks as possible. Could someone point me to a good tutorial? Starting out with the SDK can be a bit unpleasant. I'd suggest you try one of the toolkits: XLW ( http://xlw.sourceforge.net/ ) is a standard open-source C/C++ wrapper.

I have developed an Excel XLL using ExcelDNA and C#. I am at the point where I would like to begin testing the deployment, but cannot find much information that actually provides steps that work. My project was developed as a Class library with ExcelDna references. In the .dna file, I have the code below that will pack all resources into a packed version of the XLL (i.e. the Pack="true" attribute). <DnaLibrary Name="ExcelXLL" RuntimeVersion="v4.0" Language="C#"> <ExternalLibrary Path="ExcelXLL.dll" LoadFromBytes="false" Pack="true" /> I would like to deploy the packed XLL to the target machine
