I am developing a .NET application (using C#) that needs to massage some Adobe InDesign files and output their content as PDFs. I could use InDesign's scripting but the COM interfaces seem a bit cleaner for this non-interactive work. Unfortunately, I have to guess at the semantics of InDesign's COM interfaces because I don't know where ...

I have a VCL gui developed in Codegear. I have created a DropTarget for the mainform and the DropTarget object implements the IDropTarget interface which allows me to drag and drop files from explorer.

I have a VC++ COM component with a type library. The type library of this component declares an interface and a co-class: [ object, uuid( ActualUuidHere), dual, nonextensible, oleautomation, hidden, helpstring( ActualHelpStringHere ) ] interface IWorkflow : IDispatch { //irrelevant properties here } ...
Hi, I encountered strange behaviour of my application. I would like to close frame window in MDI application, so I send WM_SYSCOMMAND (SC_CLOSE) to that window. After that, I receive OnSysCommand. Then I call CMDIChildWnd::OnSysCommand to proceed processing. The problem is, that sometimes base implementation of OnSysCommand calls OnCl...
In the Microsoft.Office.Interop.Visio library each entity (for e.g Shape), is described as a class (ShapeClass) and an interface, Shape. So for each element you have: interface Shape { ... } class ShapeClass : Shape { ... } interface Page { ... } class PageClass : Page { ... } ... Why is it designed like this? ...

..for an out-of-process-server, or can I call a dispatch interface without registering a proxy/stub? The interface in question is very high level, so performance is a non-issue, and I could make the whole thing registration-free, which is a big plus ...
I have an Exchange server with lots of mountpoints. Given the path to the database files is there a way to find out what volume they are on? The problem is that they are typically not at the volume mount point, but further down the tree. I'm using Powershell, so I need a solution preferably using WMI but could also use any .NET or COM...
I guess I do have to release also late bound COM objects. But how is this done directly? In my situation I use the following code from C# to get the focused point from Google Earth (simplified): Type oClassType = Type.GetTypeFromProgID("GoogleEarth.ApplicationGE"); object oGE = Activator.CreateInstance(oClassType); object oCamera = oGE...
Hi, I'm experimenting with writing ActiveX controls and noticed that I can't seem to create an ActiveX control in Visual Basic (6.0) which features slightly more sophisticated controls. Simple controls like labels, buttons and check boxes seem to work fine, but as soon as I try to add e.g. a tree control to my form, the ActiveX control ...

Ok, I understand th...
