How to register .tlb file silently

[Harry_Potter]

I hav developed a DCOM application which requires a .tlb file of my component to be registerd on client machine, i know how to do it manually can someone help me with the silent unstallation part like installer itself takes care of registering .tlb files without user intervention.

Do you mean during the installation process? If so, read:

ms-help://MS.VSCC/MS.MSDNVS/vsintro7/html/vbtskCreatingInstallerForYourApplication.htm

If you mean you want to associate a file extension with an application OUTSIDE of the installation process, that's really just a registry entry. For example if you create a file with the extension ".Fribbleglixy" and Open With -> Notepad.exe, with Always Use checked, the following is added to your registry (exported from mine):

Windows Registry Editor Version 5.00

[HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\FileExts\.Fribbleglixy]
"Application"="NOTEPAD.EXE"

[HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\FileExts\.Fribbleglixy\OpenWith List]
"a"="NOTEPAD.EXE"
"MRUList"="a"

No i meant when you compile a com component as a remote component, u get a .vbr and a .tlb file u need to register ur type library with the client to use that component. we can do it with clireg but that' s an attended app but i want it to be unattended

I don't know then - but I strongly suspect it's still just a registry entry which you could duplicate. If you don't find the "right" way to do it I'd bet you could get the same result by manipulating the registry...
