visualBasicMacroName + " (ExecuteVisualBasicMacro)";
****WCHAR methodName [1000];
****charToWchar (visualBasicMacroName.c_str (), methodName, sizeof

****AutoWrap (DISPATCH_METHOD, & result1, pExcelWorkbooks, methodName,
errorMsg, 0);

Is the VBA method in a 'module', i.e. not a sheet.

As a visibility test, can you call it from somewhere else, say PowerShell?
