Query related to DllInstall()
-
Hi, I have a third party dll which I registered with /i option. Like regsvr32 /i:"someGUID" "DllPath" .registration succeeded. I could notice that With /i option DllInstall function is also called with DllRegisterServer. Now for me to use this dll I should call a function of it with the "someGUID" which it compares and returns successfully. 1)I would like to know what it does internally? Where does it store the GUID for comparing? The dll has some function which takes strings(file paths) as input. and displays as a list when we call another function of it. Now I close my application and register the same third party dll with another GUID to use it in another application.I have repeated the above process. When I got the list of all strings that it has it also shows the strings which it stored from the first application.I tried to find them in registry and also for any text files in the directory where the dll resides but of know use. 2)I would like to know where else can we save strings in windows other than files and registries. Thanks Satya

The source code to regsvr32 is here: INFO: How Regsvr32.exe Registers and Unregisters COM DLLs[^] Ultimately the COM interface information is stored in the registry database: HKEY_CLASSES_ROOT\CLSID HKEY_CLASSES_ROOT\AppID HKEY_LOCAL_MACHINE\Software\Classes\CLSID HKEY_CURRENT_USER\Software\Classes\CLSID

I dont understand the question, the registry is also a file. Are you asking where to save information other than a hard drive. Best Wishes, -David Delaune
