"Registering" a dll usually means calling a certain function inside the dll by the name of 'DllRegisterServer'.
COM servers could be contained in dlls and the 'DllRegisterServer' function is responsible for creating the register keys and values that are related to the server in question. Those keys and values are ProgID, ClassID, TypeLibID, interface IDs, threading model, proxy/stub and so on.
Diana Fernandez wrote: Which are the dlls to be registered?
All dlls that needs to be registered. 
Seriously, the install program takes care of this when you purchase a product.
If you are the developer you have to know whether your dll needs to be registered or not. Basically you can say "if 'DllRegisterServer' can be found in the dll it should be registered to be safe".
If you're asking for a list of dlls that are supposed to be registered I can tell you that there is no such thing. Dlls that require registring are developed each day by developers all over the world. There is no "book keeping" of all these dlls.
Hope this helps

Hello,
I dont know, how to implementate a registration script
"hInstance needs to be the module / instance handle
of the module that contains your server registration
script (resource ID 102) .."
the server registration script is importand to
register my OPC Server.
RegisterServer()
HRESULT RegisterServer(void)
Return Values S_OK upon success, otherwise the result code
returned from the ATL registrar component.
The success of this operation is dependent on the application
including a registry script resource as part of its EXE.
The resource ID MUST be 102. An example resource script
is shown below:
HKCR
{
NDI.SimulationSvr.1 = s 'NDI Simulation Server'
{ CLSID = s '{1E52DE00-FA5E-11d2-91C6-F8E932000000}'
...
Best regards

Never used ATL COM, but today I came across a little ATL COM test program, it is created by ATL COM AppWizard, all the settings are by default. a new ATL object was added into the project, and a new property Score with it.
STDMETHODIMP CContrl::put_Score(float newVal)
{
MessageBox("afsf");
return S_OK;
}
Then I inserted this ActiveX Contrl into another Dialog base project, and when Score property value was changed, the message box was prompted.
But the problem is when I add this contrl to a webpage inside Frontpage and going through the same process, the message box doesn't shows up

Hello,
I have a question related to interop between .NET and COM objects.
Many of the .NET apps I develop make use of a COM object that is accessed through the Mentor Graphics PADS software.
The PADS executables act as COM servers, allowing a VB or .NET program to "connect" to a PADS application object and its document object as a client.
The PADS applications are SDI apps, so there's always only one document object associated to the application object.
The problem I am having is that users want to be able to select one of multiple PADS servers, in case they have multiple PADS applications open. When I do a GetObject, I don't have any control over which COM object it gets.
Do you know how I can get the COM object associated to a specific server application, using Windows API or function calls, or can you point me in the direction to look for information?
Thanks,

Hi,
I wrote a word addin (Office developer 2000 - VBA) that loads at startup of Ms Word. In the document with which Ms Word starts (document 1) everything is OK. I can also run the addin several times within Document 1. When I open another (new or saved) document, document 2, the addin will not run anymore. The commandbarbutton is visible en enabeled in the commandbar, but when I click on it nothing happens.
Any help will be appreciated.
Thanks,

Hi,
We are working on development of a solution based on the RTC Client API v1.3 SDK. We want that the application we are developing should work as a service.
So we first tried to run the 'RTCSample' application as a service. For this we used a third party application that starts normal windows application through service.
Installing the service and starting the 'RTCSample' application through this service was not a problem. But using the sample application started with this way, we have not been able to connect to the LCS server.
We have confirmed that all the LCS related settings are correct. If we run that application without service it does not cause problem and we are able to connect to the LCS.
We want to run 'RTCSample' application as a service. So can you please help us how to make it as a service?
If there are any limitations on the RTC API regarding the service mode, please let us know.

I am having trouble with running one of my ASP.Net application. The problem is that the application runs another exe application using the process object and the exe in turn generates some output files but the output files are missing while running under ASP.net application scope. It runs fine when run through a console application or asp application. It is a problem specific to ASP.NEt application. Maybe something related to user permission under which the application is executing but i an not able to figure out the problem. Anybody out there know how to solve it please help.
thanks Ramendra

Any help would be appreciated...

What does this have to do with COM ? How do you call the exe ? Does it fail ( i.e. does it blow up, or can you just not see the result ) ? Can you control the exe to see what's going on ?

It has nothing to do with COM. I am calling the exe using the process object of the .net framework. It doesn't fail just returns without creating the output files. It doesn;t blow up. I dont know what you mean by controlling the exe. I call the exe application using the process object.

Well, why did you ask in the COM forum then ? :P

What is the exe ? Did you write it ? If so, can you change it to help you work out what the problem is ?

I mean, is it yours/do you have the source code.

No i didn;t write the exe and cannot change it. I have to use as is and make it work.

Then you need to check the debugger to make sure it's being called properly, and apart from that, just check that the asp.net process has permissions to create files where you're trying to create them.

I was wondering whether we can FTP from different host (places)using TAPI .basically,all knows TAPI usually used for telephone action & also can be use for dial up,but for FTP, is it possible to use it.Actually, if using via internet, this of course can be done,but for security purpose,we intend to use dial-up only.
so,anyone with that knowledge,please enlighten me

I think RAS will do what you want to do, which I'm assuming is establish a TCP/IP connection over dial-up.

Try asking in the C# forum instead of the COM forum.

I would like my COM object to expose the functionality to export itself into different binary representations into an output stream. E.g. to render itself into a stream as PDF or as JPEG, etc. The functionality itself is already available, but I don't know how to expose this function in terms of standard COM interfaces.
I looked at the IPersistXXX interfaces but they don't allow to specify the target format but assume that the format is inherent to the object. Also for every output format there are potentially format dependent options that need to be passed in.
IPersistMoniker looked promising but I am not sure if the intent of this interface is the export into different formats.
I would like to reuse existing COM interfaces if possible rather than defining my own interface.
What do you recommend?
Best regards
Carsten

There is the IPersistFile which has Load(filename) and Save(filename).

Hi Vita.
Right, but how does the interface allow me to export my object? I would guess the correct format by evaluating the file extension, but that won't work if want to stream the content instead of writing it to a file (IPersistStream). Also IPersistFile does not allow me to pass extra information to configure the export process, such as target width/height of an exported bitmap or the compression ratio for JPEG.

Right, but how does the interface allow me to export my object?
As usual IPersist* interface. If you try to find some export interface, so you can use the exact IPersistFile. If you aren't able to choice the export interface, you should implement the exact one required by client.
I would guess the correct format by evaluating the file extension, but that won't work if want to stream the content instead of writing it to a file (IPersistStream).
The stream stores the binary data which presents this object (see OleLoadFromStream). There is no matter which format the object used to be stored.
With best wishes,
Vita
