Hello! I am writing simple application (on VB6 first, then VB.Net and C# with the same result) that uses the control MsRdpClient2 from msrdp.ocx. Everything works well until I install Remote Desktop Connection 6.0 client update (KB925876). My application now said it cannot load this control from msrdp.ocx. Cheking msrdp.ocx file ... and found it's still available in "C:\WINDOWS\system32\web\tsweb\". Then simple test "regsvr32 msrdp.ocx" ... and now my application works again (but seems it's not good idea to do this on any computer except test lab). Doing registry state comparision before and after update installed shows that MsRdpClient2 now lives in mstscax.dll and if I understand correctly it's not now UI control( ). Now seems like I messed up a bit: how can I use this control now Please advise. Thanks.

Terminal Services Control (msrdp.ocx) vs Remote Desktop Client 6.0 (KB925876)

Try to add both references to your project,
add the two controls to your toolbox,
verify that the references DLLs are copied to your project,
It may work, the program will call them from its directory instead of \SYSTEM32.

xyligun,
I suggest you to take a look at the related knowledge on the COM Interop that contains the .NET Framework and COM/COM+ interopation with invoke each other. After that, I believe you will have a better understanding your questions and the answer post provided by aybe.
Here will give you the link in msdn on COM Interop:

There is also a book titled Building Distributed Applications with Visual Basic .NET written by Dan Fox. I am reading this book these days and would like to introduce this book to you. Just share the knowledge :-)
