I've uploaded ExcelDna version 0.11 to http://exceldna.typepad.com/blog/files/ExcelDna-0.11.zip.
This version should fix the mysterious loading errors reported since version 0.8. The problem was related to Visual Studio 2005 Service Pack 1, which has a new version of the C runtime libraries. The
embedded manifest in recent versions of ExcelDna.xll required the new version of the CRT to be loaded with ExcelDna. I have now changed the manifest that is embedded to require the RTM version as before.
Please let me know if you still have errors loading ExcelDna with this version, also on Excel 2007.
Other significant features and fixes since version 0.7:
* Fixed bug when library had function with object and object[,] arguments.
* Fixed bug when more that 20 arguments. (At most 20 argument descriptions are allowed.)
* Methods can be dynamically registered in the AutoOpen method of an AddIn.
ExcelDna.Integration.XlLibrary.RegisterMethods(..) takes a list of MethodInfos to register. See sample08.dna for an example.
* Arguments of type object and double now also accept single column values. If the range passed in has exactly one column, that column is used as the array. If more than one column is passed, the first row is used, as before. object[,] and double[,] have not changed.
As always, your feedback is much appreciated. Please post your comments or questions at the ExcelDna Google Group.
