COM server exe import

Hi all.. Im importing COM server exe which on the remote machine in my client program..But I'm not able to import..I'm getting fatal error C1083: Cannot open type library file: '\\remotemachinename\FileServer.exe':
This is the import statement:
#import "\\remotemachinename\FileServer.exe"
using namespace FILESERVERLib;


Thank u...

hi,

is it working on same machin ???


-Anant

Yes its working on the same machine..

Actually I do not know what kind of import statement I should specify...

Thank u..

Hi,


check the section "Search Order for filename" in
http://msdn.microsoft.com/en-us/libr...b6(VS.71).aspx

Thank u...I ll go through and let u know...

I have a doudt.. Does importing a tlb file and an exe file differ? Any way the client needs the the location of the COM exe for requesting the interface.. Whats wrong with my import statement ?

Hi,


might be there is any issue with the path specified.. !

Hi.. Can u please help to resolve my problem....

I'm not quite sure, but think the network path for COM server is not good. I never met some explicit instruction that the thing is forbidden, but my impression always was that any kind of COM server must be located locally, unless it's DCOM server (which is totally different story).

BTW, what is your exact intention for having the server's .exe remote?

Actually thats my project... I have been asked to test my COM on a remote machine and to find the solution if network is down or the process itself crashes things like that... But, my initial step itself doesn't work and could'nt proceed further ...First I must try to connect the COM on the remote machine..Do u have any idea like how to do?
Thank u...

Its something similar to DCOM ....

It can't be "something similar", it's either DCOM or not.
In case it's DCOM, an appropriate COM/RPC error must be produced in case of network failure.

FYI: I have placed one of my own out-of-proc COM servers onto network share and compiled my .cpp with #import "" instruction pointed to the server. It has been compiled with no problem.

Actually, the path '\\remotemachinename\FileServer.exe' is something weird in terms of networking. UNC path (which ) is build of following components:

\\server_name\share_name\rel_path

So your path just points to FileServer.exe share on remotemachinename host (and therefore, contains no relative path to a COM server or type library that could be imported). I doubt this is what you had in mind. ;)

Thank u.. But its not the share on remote machine..Through my code i should be able to call a process running on the remote machine...how can i do that?.. Should I have to build proxy/stub ?
Thank u..

Now, finally, is that or is that not a DCOM server? If yes, you register its copy locally (progid, appid, type library, interfaces, CLSIDs, etc.) and then tweak it by means of dcomcnfg.exe utility. Google for "DCOM configuration".

Proxy-stub dll is typically built along with the COM server, you just need to register it.

Hi.. Now a new error has creeped in.. When I'm trying to create instance on remote machine it gives me ACCESS DENIED error... I have set security permissions for the DCOM though...

Thank u

Hi.. I tried the code.. When I'm trying to create an instance on the remote machine I get ACCESS DENIED error.. I have the security permissions for the DCOM though..
Thank U...

Okay, you have access denied error. Do you think this information is enough to solve your problem? Knowing nothing about your server, the precise DCOM settings you set, the code of your client app, all that stuff that really matters for success? You must be kidding...

My advice I always provide in such misty cases:
1. Put aside your current project.
2. Implement a minimalistic application (server and client in your case) that reproduces your problem. As minimal as possible.
3. Solve the problem in your small model.
4. Bring the solution into your real-size project.

Thanks for the offered help... I'm a beginner in VC++... K Let me try out... Thank u once again...
