You need to specify the std:: namespace: std::cout << …. << std::endl;; Alternatively, you can use a using directive: using std::cout; using std::endl; cout << …. << endl; I should add that you should avoid these using directives in headers, since code including these will also have the symbols brought into the global namespace. Restrict … Read more
Make sure your Com is public and visible. To do this, add these tags to your Com class: [ClassInterface(ClassInterfaceType.AutoDual)] [Guid(“41E90F3E-56C1-4633-81C3-6E8BAC8BDD70”)] [ProgId(“……….”)] [ComVisible(true)] public class MyCom { Make sure your COM has been registered. You can do this using the command line: C:\WINDOWS\Microsoft.Net\Framework\v4.0.30319\regasm “C:\…….\xxx.dll”
You might be calling the workSheets method from within a static function. Try moving it out. Or, have you tried explicitly declaring the data type of ‘Worksheets’ WorkSheets :: Int -> Int or (whatever type is should be).
According to Windows Vista Security Model Analysis you will need to use shared objects such as a named pipe to go between the different IL. Also, the shared object should have an IL equivalent to your lowest IL being used.
Workaround rowCnt := UsedRange.Rows.Count; colCnt := UsedRange.Columns.Count; for Row := 1 to rowCnt do begin for Col := 1 to colCnt do begin v := UsedRange.Item[Row, Col].Value; end; end; This also works (and may help you find a workaround in more complicated use cases): function ColCount(const range: ExcelRange): integer; begin Result := range.Columns.Count; end; for … Read more
I was trying to do similar thing. I concluded that the COM library provided by Microsoft is incomplete. I don’t use it because the doc mentioned that “Note: This topic is pre-release documentation and is subject to change in future releases”. So, I decided to take a look at what IISExpressTray.exe is doing. It seems … Read more
When a DLL is registered, the DllRegisterServer method entry point in your DLL is invoked. Similarly, DllUnregisterServer is invoked when a DLL is unregistered. As described in this MSDN article: Instructs an in-process server to create its registry entries for all classes supported in this server module. If this function fails, the state of the … Read more

If I recall correctly — and my memory on this is a bit fuzzy, it has been a long time since I took the Excel PIA apart — it’s like this. An event is essentially a method that an object calls when something happens. In .NET, events are delegates, plain and simple. But in COM, … Read more
