Most probably the tlb is stored in the dll as a resource. If you have visual studio open the dll and select the open type to be Resources. That way you can view the TLIB resource section and export from it. Some versions of VS dont support this, but it used to work with VC6 for example. I guess the Express editions dont provide resource editing.

BTW, a simpler way that might work is to use 7-zip to extract the dll and find the tlb there. I havent tried it for TLB but it works for other resources like icons.

You could use the "OLE/COM Object Viewer" (oleview.exe) that ships with Visual Studio to extract the TLB.

Both of these ways are correct but I am looking for a command like tlbexp (which work only for managed DLL) becuase I want to extract tlb at runtime and use it.

you can use 7zip exe or dll (SDK) for that.

And as a last resort, write some code to  extract it.
