COM technology is also a standard way to package downloadable code (which is what ActiveX controls do). Even methods of interacting with the native OS can be specified using COM, for example, in Windows and Windows NT, where new APIs are used, most of which are defined as COM objects. It can be seen that COM, although originated from compound documents, but it is effective for many software problems, it is at the bottom of the basic technology. In a word, COM is a language-independent component

AxHost.Next you had to add the control to the form's Controls collection so it was visible and usable. You cannot call any interface methods until the control instance are created, that doesn ' t happen until you ' ve added the CO Ntrol and the form ' s Load event has fired.Next you has to use reflection or the dynamic keyword to obtain a reference to the interfaces implemented by the control, In the need to set properties or call methods. That's difficult to get right, and you'll want to write

It is said that delphi5 has always had this bug with Delphi7, and I don't know if it has been changed in a later version. I use Delphi7. I don't know much about delphi. ocx is also used to catch ducks. I cannot understand the cause of this bug, but I did solve the problem. I will explain the solution below (in fact, I also searched the website and sorted it out a little) 1. Go to the Delphi installation directory and find the source \ VCL

How to solve? Method One:Re-register the following DLL file, you point "start", "Run" on the desktop: regsvr32 Shdocvw.dll regsvr32 Shell32.dll (Note this command) regsvr32 Oleaut32.dll regsvr32 Actxprxy.dll regsvr32 Mshtml.dll regsvr32 Urlmon.dll Note: The second command does not have to lose, you can restart Windows after you finish the command, and then re-enter the second command if it is found to be invalid. Method Two:It is also invalid if a method is used to re-register regsvr32 Olea

It is worth noting that this problem is encountered during the development of OCX controls. The debug version of the program can be compiled to run normally, but the release version when the registration failed, prompted not to find the module, using Depends view, Missing libraries such as Avcodec-54.dll, which are used in ffmpeg, are already in the program directory, and debug compiled programs can correctly Identify these libraries and register t

1. Open vc6.0, create a project, and select "MFC ActiveX controlwizard". The default setting is as follows; 2. on the classview, you can see that there are mainly ** app \ ** CTRL \ ** progpage classes, and the interfaces are mainly implemented in ** ctrl, you can use the automation page of MFC classwizard (CTRL + W) to create interface functions; 3. The interface function is external, so pay attention to the parameter type definition. I generally use the lpctstr character, as shown in the f

1. Set the initial widget size. First, we need to set the initial size of the control to its static size using the COleControl::SetInitialSize method. This should be done in your control's constructor like this://////////////////////////////////////

Custom messages cannot be defined in ATL as in MFC, because there is no concept of MSG map in standard ATL, and if you are doing ActiveX, you can msg to window, ATL provides macros of the BEGIN_MESSAGE_MAP category: First, define the message ID:
