I think you need Copy Hook Handlers[^]

Copy Hook Handlers seem to be the trick.. Until you notice that they only work for folders and not for files 
|
|
|
|
|
How about SHChangeNotifyRegister, FindFirstChangeNotification/FindNextChangeNotification or ReadDirectoryChangesW
I had actually done this hooking but it's been more than three years now so I don't really recollect how I did it. all I remember is using some of the above API's 
Let me know if this helps

Dear All,
I need to develop COM Component. I know the basics of COM functionality.
But I dont know how to develop an interface for my program.
Can anybody help to develop that interfaces ?
bye

I would argue that if you don't know how to make a COM interface you don't know the basics of COM. Interfaces are the cornerstone all of COM is build from.
That said, the normal starting point (in C++) is to create an .IDL file that describes your interface. This file is then compiled by MIDL which creates the type library and header files which you consume using C++. Your IDE will be able to do some of this work for you.

Please help me.
My problem is that I developed a COM component. I can use
REGSVR32 c:\COMDLL\AuthEngineCOM.dll
to register the COM in a computer which has Microsoft Visual Studio .NET 2003. But when I use
REGSVR32 c:\COMDLL\AuthEngineCOM.dll
in a computer without Microsoft Visual Studio .NET
a error appear:
LoadLibrary ("c:\COMDLL\AuthEngineCOM.dll") failed - The specified can not be found.
Could somebody tell me which dependence that I missing?
Thanks,
William

Hi
You just copy your dll file "AuthEngineCOM.dll" and paste it into C:\\WINDOWS\System32\
After that try Run->regsvr32 AuthEngineCOM.dll

Hi,
I have Visual Studio 2005 and my regsvr32 also fails with the message "testdll.dll was loaded, but the DllRegisterServer was not found".
I have copied it to the Windows/System32 folder as well.
Kindly help me out here.
Thanks

Hi
Every Dll file should contain DllRegisterServer Function.
Here your Dll file test.dll might not have that DllRegisterServer Function inside.
If so you can not register that file through RegSvr32.exe .
|
|
|
|
|
DllRegisterServer is one of the key function that needs to be implemented in a COM server (.DLL). This function needs to be exported from this DLL.
Please check if you have exported this function from your DLL. Also, you can use Dependency Walker[^] to see the dependencies of your DLL as well the functions that are exported.
I hope this helps. Let me know if you need more information.

At a guess you've built using the dll runtime and it's not present on the machine. Use a dependency viewer on the target machine and make sure all the DLLs you're component depends on are present. One can found here[^].

You can use Dependency Walker [^] to see the dependencies of your DLL. You can find the missing dependencies using this.

Hi William,
try to use depend.exe with your dll in order to find the missing dependecy.
Cheers Carlo

Hi
I think the problem is the COM (dll) dependencies, maybe your COM has references to another dll that doesn't not exist in target pc.
You can see referencias with Dependency Walker (Visual Studio Tools)

Hello William,
I also had this problem.
I solved it by using a tool called DependencyWalker. It is provided
with the VisualStudio IDE. Analyze your COM-Dll with this tool and you
will see the modules/dlls that are missing on your system.
Cheers,
Norbert

To all the gurus at Code Project I'm running into an issue using VB.NET DLL withing Powerpoint VBA code.
I created a comClass object in VB.NET, built the DLL and in Powerpoint I'm referencing this DLL and class object.
The very first time the "Call VBNETComClass.GetID" line of code is executed, it takes 10-15 seconds for the code to actually execute. Does anyone have any idea on 1) What is causing this issue, and 2) How do you fix it?
If you stay in Powerpoint and call this comClass again the second time, WHAM...opens up instantaneously.
Thanks so much!!!

No need to respond to this issue anymore as it has been resolved.
I created the problem by copying a comClass object in the Solution Project, and then doing a paste to create "another" comClass object. When I tried to build the solution, I got a "duplicate GUID's" error. DUH!! So, what did I do next? I created another comClass object, took it's generated GUID'S and loaded them into the comClass I just pasted (so now the GUID's are unique and the Solution built). NO CAN DO!!!! Those GUID's I copied into the pasted comClass we're and always will point to the generated comClass. So, when you reference the DLL and its classes in VBA, and do your first instantiation, it's looking for the wrong GUID's. So it goes through the whole registry, finally finding the correct object.
