1. Introduction. 1.1 This article is a follow up to my last blog Programmatically Register Assemblies in C#. 1.2 In that article, I mentioned that I will be writing more to explain implementations for the ITypeLibExporterNotifySink interface as used in the context of a call to TypeLibConverter.ConvertAssemblyToTypeLib(). 1.3 I will dive straight into exploring this … Continue reading
1. Introduction. 1.1 After publishing Programmatically Register COM Dlls in C# back in 2011, I received a number of requests for advise on how to register managed assemblies as COM servers. 1.2 In this blog, I will present the reader with a sample C# program that will perform such registration. 1.3 The sample assembly COM-registration … Continue reading
1. Introduction. 1.1 Recently, a friend asked me for advise on a very unusual requirement. 1.2 He needs to replace all UUIDs in a COM DLL with new ones. 1.3 He does not have the source codes to the original COM server so any modifications will have to be done on the binary code. 1.4 … Continue reading
1. Introduction. 1.1.

1. Introduction. 1.1 This blog is the third segment of the series of articles that discusses the problems and workarounds in relation to passing a reference to a SAFEARRAY as parameter to a dispinterface-based event which is fired from an unmanaged COM server to a managed client. 1.2 In part 2, I presented a workaround … Continue reading
1. Introduction. 1.1 This article is a follow up to my earlier blog which outlined the problems with passing a reference to a SAFEARRAY as parameter to a dispinterface-based event which is fired from an unmanaged COM server to a managed client. 1.2 Through this article and the next one to follow, I will demonstrate … Continue reading
1. Introduction 1.1 I recently ran into an unexpected problem with the .NET CLR. 1.2 It appears that its internal internal mechanism for processing COM events inadequately handles reference SAFEARRAYs passed as event parameters. 1.3 In this blog, I will demonstrate the problem with sample codes. It is my hope that interested readers will research … Continue reading
