And also, it didn't really matter whether the DLL or OCX file was registered through an installer or manually.

In this way, programs (during installation) could update DLLs and OCXs without (hopefully) disrupting other programs that also used them.
Rather, the way I've always understood things is that, any application that needs a particular DLL or OCX, simply looks in the registry for it, checks that its version is equal to or greater than the one it needs, and then uses it (based on the registry information). I wasn't under the impression that a DLL or OCX kept track of how many applications used it.

because tec Windows 'counter' (that register the numer of applications used by the component) will not updated. You may be thinking that all this makes the task very difficult or tedious – I totally agree. (IMO for VB6, that line should be drawn rather liberally). Somewhere in that mapping you can draw a line between what you need to deploy and what the operating system or other runtime environment can be relied on to provide. So really you need to "walk the links" of all the dependencies until you build up a complete mapping of what is required.
Alternative for no source code: as in the case above. #Download oppo launcher code
You also need to know what the configuration state will be on the PC that runs the code - which DLL files are registered, assuming a manifest is not used.
To identify: You have to look at the source to know what might happen. The activation context is established by the app manifest file (if there is one) or the Windows registry otherwise (the normal default for VB6 programs). Which DLL will be used to provide the class will be determined by the process’s activation context. Classes can be loaded arbitrarily using eg VB6 CreateObject() calls. Alternately if you don't have the source you could use tools like Process Explorer and/or Process Monitor to observe a running instance and see what DLLs actually get loaded. DLLs can be loaded arbitrarily using Win32 API such as LoadLibrary(). NET would be using ILMerge to combine assemblies.Īt Runtime for traditional DLLs (not COM) Something like a C linker could use libraries like this. As far as I am aware, this is not possible for VB6 programs. Therefore there is no runtime dependency to anything external. Library code is included in the EXE or DLL which is being compiled. You might need to look up some GUIDs from there in the registry to see what actual DLL files are used.Īt Compile time for statically-linked libraries (not COM, not DLLs) To identify (alternate): If you don't have the VBP or source code, these dependencies can generally be revealed by by IMPORT statements in OLEView. 
To identify: These are listed in the project VBP. Note that the dependency is actually on the COM class or interface GUID, and not explicitly on the DLL file itself. This includes VB6 code which has explicitly set a reference to a DLL or OCX. In VB6 this is known as “early binding”. To identify without sources: These can be detected by a tool like Dependency Walker. NET this would mean calling out into “native code”) 
This includes VB6 code which has used a statement like: Declare Function … Lib …. Files are (as their name suggests) dynamically loaded at runtime based on the linking process done at the end of compilation. 
Mechanisms which establish runtime dependencies:Īt Compile time for traditional dynamically-linked libraries (DLLs which are not COM) This answer is specific to VB6 but many other programming languages would work similarly. Ideally you would need to account for all of them: There are many ways in which runtime dependencies on DLLs (or OCX files) can be established.
