Hi,
My project is with VC2010 . I use from a dll in this project. i register and use ".tlb" file of this Dll.

#import "C:\Windows\System32\MyDll.tlb" raw_interfaces_only

How do i determine the version of current dll, that is registerd in my system, when i'm compiling the project?

I want:
the exe logs, the version of Dll that exe is compiled with that
I mean:
I want to check Dll Version in compile time, (not runtime!!!)
I want to show "compile time version", in a Static box in about dialog.

What I have tried:

I want to show "compile time version" of Dll, in a Static box in about dialog.

Check the linker logs to see if they provide that information. You may need to use the "verbose" option.

How do you think that can be achieved without writing a program to do it?

You have to create a user defined build step that makes this informatiomn available to your application before compiling. See Understanding Custom Build Steps and Build Events (VS 2010)[^].

A possible solution would be writing a batch / command file that gets the version string from the DLL and creates a header file containing a single line with the definition for the version string. Your about box dialog source file can the inlcude this header file.

To get the version from the DLL you need a command line tool. One solution is using the PowerShell with

(Get-Item path-to-dll).VersionInfo.FileVersion

Another solution is to use the Sigcheck[^] utility from the SysInternal tools.

Or write our own utility that reads the information using the GetFileVersionInfo function (Windows)[^] and creates the header file.
