1. add an item to the context menu from a right click in the background of a folder in explorer (not a right click ON a folder)
2. add an item to the context menu from a right click on an exe file
First question is... can I do this with ONE shell extension or does it have to be two separate modules? I'm really hoping I can do it all at once.
Secondly, I'm wondering what the best way to "package" a shell extension is (for easy installation later). Right now the DLL is being accessed from my project folder but that is just a temporary solution. I need to install it somewhere....where should it live and what's the best way to get it there? Should I create an installer of some sort?
You could do that with one or two extensions. IShellExtInit::Initialize() is called with different parameters when you click on a file versus the background, so you can tell those two cases apart. Check out part 1[^] and part 7[^] of my shell extension series for more details.
Having two extensions doesn't mean you need two DLLs. Each extension is just a coclass, and there's nothing preventing you from having multiple coclasses in one DLL.
Thanks Mike! I figured this was possible so I'll keep working on it. I've looked at your part7 tutorial, and you created two separate classes that derive from IShellExtInit, so I'll need to do this as well, right? It seems like I'll need one to handle right clicking on a file, and one to handle right clicking in the background. I don't see how else IShellExtInit::QueryContextMenu can differentiate.
In the case where you right-click files, Initialize() gets an IDataObject* that contains the list of selected items. In the case where you right-click the background, Initialize() gets a PIDL that tells you the folder.
Is there any way to get the instance of EXCEL.EXE from Process ID using COM?
Similar to GetActiveObject, is there any other thing through which we can get the instances of multiple EXCEL.EXE running in Task Manager?
After getting handle to each EXCEL.EXE, I want to track all workbooks and sheets. I am using EXCEL automation to do this using C++. Getting all workbooks and sheets is done. But after getting PID of EXCEL.exe's , how to get that object?
I am getting PID for each process using psapi.h.
I think I am not asking a question, which I am not supposed to or I shouldn't ask.
In C#.net we have BinkToMoniker to get the object. Is there any such thing in C++(unmanaged).
