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. I'll post it immediately after this post.Īlright, I'm confused.

I had also written a response to meopilite but was having connection problems. This is very specifically known as DLL hell. If any of that is wrong, I'd be delighted to learn how.Īlso, basically, the only (and LARGE) downside to this "version checking" approach is when a newer version of a DLL or OCX changes the way some call works such that it fouls up programs that expect it to work in an older way. And also, it didn't really matter whether the DLL or OCX file was registered through an installer or manually. because tec Windows 'counter' (that register the numer of applications used by the component) will not updated.

Per-machine self-registration information is stored in the registry key HKLM\SOFTWARE\Classes\CLSID, and per-user self-registration information is stored in HKCU\SOFTWARE\Classes\CLSID a merged view of the data is available under HKCR\CLSID. For details, see Self-Registration Methods and InstallShield Self-Registration (ISSelfReg). msi database, and adds some custom actions related to self-registration to your installation Execute sequence. When you mark one or more files as self-registering, InstallShield adds data to a table of your.

In addition, if you use any type of self-registration in a patch, the patch will not be uninstallable. InstallShield self-registration (ISSelfReg) enables you to overcome this limitation.ĭllRegisterServer generally does not register a file with a relative path, as needed by systems that support side-by-side sharing. Self-registration may require COM servers to be registered in a particular order.

ocx file as self-registering, the file’s own registration function ( DllRegisterServer) is called during installation to register it with the target system, and its unregistration function ( DllUnregisterServer) is called during uninstallation to unregister the file. For more information, see Targeting 64-Bit Operating Systems. Tip:If the self-registering file is part of a 64-bit component, 64-bit self-registration occurs on the target machine. For more information, see Dynamic File Link Settings Dialog Box. You can specify that a dynamic link is self-registering. For more information, see File Properties Dialog Box. You can specify that a particular file is self-registering. InstallShield supports different methods for indicating that a COM-related file (.ocx. If you have a COM server that is self-registering, you can call the COM server’s self-registration functions at installation time to register the COM server on the target machine.
