Hi, Have you generated the ProjectInstaller class? It should look something like: [RunInstaller(true)] public class ProjectInstaller : System.Configuration.Install.Installer { ... } Regards David

Have you read the info at http://msdn.microsoft.com/library/default.asp?url=/workshop/browser/hosting/wbcustomization.asp[^]? Unfortunately, all the examples are unmanaged C++. You may need to implement the GetHostInfo() method so as to return appropriate values in the DOCHOSTUIINFO structure. Also you maybe need to return S_FALSE from the TranslateAccelerator() method. I did implement this interface some time ago in unmanaged C++ and I'm trying to dig up some old source code. Also notice that someone else had a working C# implementation of IDocHostUIHandler at http://www.thescripts.com/forum/thread257999.html[^] Regards, David -- modified at 23:33 Wednesday 28th February, 2007

If you have control over the binary file format, this may help. Make sure that one of the attributes in the fixed length header is the length of the following JPEG image data. You could then create a byte array (byte[]) of the length of the JPEG image and read the specified number of bytes to the byte array using: BinaryReader.Read(byte[], int index, int length)

You could try REGASM Assembly.DLL /CODEBASE. That way the current location of the assembly is recorded in the registry. David
