So far I have tried ISpy and received "This file does not contain a managed assembly." I also tried PEBrowse but couldn't even open it without getting an error
mshtml.dll is the rendering core of Internet Explorer. It is written in native code, not .NET so therefore it cannot be decompiled as "managed assembly". It is "unmanaged" code.
If you are reverse engineering some module, you may treat the call to MSHTML a native call.

Hi this may sound like a dumb question, but I am trying to use the NReco PDF library in my VB.NET Win Form application, and I am getting this error when I try to compile my code:
NReco.PdfGenerator.HtmlToPdfConverter' is not defined
I added the reference to the DLL and when I first wrote this code:
Dim converter As New NReco.PdfGenerator.HtmlToPdfConverter
It recognized the NReco namespace and everything seemed fine, but whenever I try to compile it acts like the DLL is missing. I know this library is written in C# but the site just said it was a .NET library, and I have used other libraries written in C# with no problem.
Any ideas on why this isn't working?
I never could figure out why NReco wasn't working, but I did find a pretty awesome alternative that works very well.
Nuget Package: https://www.nuget.org/packages/Pechkin/
Source Code: https://github.com/gmanny/Pechkin
This library uses WebKit Engine to convert HTML to PDF and it does a very nice job of rendering things correctly thanks to WebKit.
It is relatively easy to use and it is free to use under the creative commons license. I highly recommend this library for anybody wanting this functionality for free.
I'm trying to reference a com component and it is throwing the below error.
Creating an instance of the COM component with CLSID {xxx} from the IClassFactory failed due to the following error: 800a0153.
Specifically the error gets thrown when I try to instantiate an object. I checked that
The project being built for x86 processors which it is
The com object is registered using regsvr32, and is available in the registry.
I can also see the methods in the object browser, so I know .net is finding it.
Any ideas on what I'm missing?
This is an error code that's specific to the component. If you don't have documentation that explains what the code might mean then you'll need support from the vendor.
As noted in my comment to Hans' answer, this error code is FACILITY_CONTROL, which is supposed to relate to OLE/ActiveX controls, and has an error code which lies in the standard range (i.e. for Microsoft use) defined in OleCtl.h, but is not documented in the Win32 header files so is probably internal to a Microsoft product such as Visual Basic.
Can you tell us anything else about the COM component you are trying to use?
If the COM component was written using Visual Basic, I think it's probable that what you are seeing is equivalent to the Runtime Error 339 which users of Visual Basic see if they try to reference an OCX control which has some of its dependencies missing. You might look at the dependencies of the COM server's DLL/EXE using Depends.exe and see whether you have them all present on your machine.
Back when I had to do a lot of COM work, I used COM Explorer quite a bit from these guys:
http://download.cnet.com/COM-Explorer/3000-2206_4-10022464.html?tag=mncol;lst
I had to install it last year to debug a bizarre COM registration issue with Office plugins.
Also, I have no affiliation with these guys whatsoever (and it looks like the company might be toast anyway).
When creating dlls (Add-ins) for a third party program that loads Native DLLs dynamically, is there a way, in a Mixed Mode DLL (C++/cli) to natively catch the fact that the .Net framework is not available. So that the Parent program that is dynamically trying to consume this DLL does not throw an error?
It might be possible to do something with a custom entry point in the dll, but I expect you are walking in 'undocumented' territory.
The only 'simple' way I can think to do this would be to create a native shim dll that performs the check and handles the condition in whatever way you see fit. If the framework is present it in turn loads the real plugin DLL and mirrors all calls through to it.
How easy this is will depend on the complexity of the plugin interface you are working with.
I am using C# and Visual Studio 2008.
I have a class that will turn on the scanner of my Windows Mobile Device and then will capture the read of the scanner when pressed. It will also shut down appropriately and cleanly. I am using a vendor provided SDK to do a lot of the heavy lifting.
I have this working correctly in a Mobile App, but I also need the dll to be able to be called via COM/ActiveX from a web site. I have been going around and around about how to do this. I've bounced between various settings and project types. I've tried converting it over to C++ and ATL. But so far nothing works.
I get conflicting information depending upon where I look. I need help. Can only C++ do this? Is there something I'm missing? I can't be the only person needing to do this. How can I do this?
You cannot create ActiveX/COM components in managed code with the Compact Framework. There is not EE Hosting support, so it simply cannot be done. You will have to write this in C++ (not managed C++, but old-fashioned native).
As a side note that is sometimes overlooked on COM controls, you also have to implement IObjectSafety for the control to work in a browser.
I have a interesting problem: Where I work we've built a home-grown ERP system in VB6 that we are slowly moving over into vb.net. There are some projects have are in .net: we have a hand-held C# project that uses a web service to talk to our database, I've built some reporting screens using Crystal and some smaller maintenance screens.
Well as we have been plotting the conversion out, we want to have a way to separate our business logic and UI so that the UI can be a win/web form or a Smart Device project. Is this even possible? I try to reference the DLL in a test I have and it gives me this error when trying to debug using a emulator
Deployment and/or registration failed with error: 0x8973190e. Error writing file '%csidl_program_files%\smartdeviceproject1\system.windows.forms.dll'. Error 0x80070070: There is not enough space on the disk.
I'm not sure what it's doing... I take my DLL out and it works fine. Does anyone know of a way I can create a DLL that can target all of these UI without may changes?

helped me alot. Using a linked projects with conditional complation would seem to work in my case.
