.NET Forum / Languages / Managed C++ / September 2005C++ namespace for Excel application
All, I cannot find any examples of doing Excel automation from a VC++ .Net environment. Does anyone ay least know what the namespace should be to expose the Excel app? i.e. using namespace System::????????????????? TIA, Bill > All, > [quoted text clipped - 3 lines] > > using namespace System::????????????????? Are you doing managed C++ or native (aka unmanaged) C++? For managed, you use the same manage PIAs (Primary Interop Assemblies) and namespaces as you would for C# or VB.NET. For unmanaged, you program Excell through it's OLE Automation (aka COM) interface. Your best bet to get started is to look up the #import compiler directive, and then try #import "progid:Excel.Sheet" The #import directive will create C++ wrappers that allow you to call the OLE interfaces as comfortably as you could from VB6. The declarations will be (by default) placed in a namespace with the same name as the library. IIRC, you may also need to #import one or more common MS Office type libraries (e.g. MSGraph.Application) in order to have full access to the Excel API. -cd I am doing managed C++. I cannot seem to get the reference to the Excel "object". I have the following references: Excel Microsoft.Office.Core I cannot seem to figure out how to declare an Excel app from C++. I also notice that intellisense works with all the references except for Excel. Any pointers to examples that you can share. I have been googling around in my spare time but cannot find anything useful (so far). TIA, Bill > I am doing managed C++. I cannot seem to get the reference to the > Excel "object".

I have no experience controlling Excel from managed C++ (or any managed language, for that matter). You might try posting in microsoft.public.dotnet.framework.interop and/or the VSTO group where you probably have a better chance of finding someone that's been down your particular road before. -cd
