kaylanreilor:

The error means that the class is not registered, so when you use regsvr32 what is the message ?

02.11.2008 at 04:50AM PST, ID: 20865810

kaylanreilor:

I suppose that when you use tlbimp you write something like this:
tlbimp sapi.dll /out:NETSapi.dll
And then in your .Net project you add a reference on NETSapi.dll ?

godwindotnet:

Hi thanks for your quick response.

I got this message. When I register the com component regsvr32 sapi.dll
"DllRegisterServer in sapi.dll succeeded." appears at messagebox.
I tried your second suggestion also.
TlbImp sapi.dll /out:speechlib.dll ,
but that also not worked for me. Somebody is telling that I should register as DCOM object I tried that by dcomcnfg tool but I don't know how register as DCOM object. And also I tried installing as COM+ service in dcomcnfg tool.
Please tell help me out.

02.11.2008 at 05:14AM PST, ID: 20865955

kaylanreilor:

You have to register it if it is supposed to be used from another machine.

I just realize that you don't need any Type Library Importer tool because SpeechLib.dll should already exist on your machine.

If I add a reference on SpeechLib.dll and I do something like the following, it works for me :

        private void SampleControl_Load(object sender, EventArgs e)
        {
            SpeechLib.SpInprocRecognizer rec = new SpInprocRecognizer();
            SpeechLib.SpCustomStreamClass sp = new SpCustomStreamClass();
        }
    }
}

Just a small correction:
"You have to register it if it is supposed to be used from another machine." => I meant registering AS DCOM OBJECT.

02.12.2008 at 03:13AM PST, ID: 20873889

godwindotnet:

Hi,
No I don't find any dll speechLib.dll in my system.
I know normal regsv32 registration, How do I register as DCOM object?
Thanks,
R. Pandiarajan.

02.12.2008 at 04:59AM PST, ID: 20874311

kaylanreilor:

Open Visual Studio 2005 Command Prompt. Navigate to where sapi.dll is located.
Then execute this line:
tlbimp sapi.dll

=> tell me what's happen but the principal result is that the last line displayed should be "Type Library imported to SpeechLib.dll"

02.12.2008 at 05:00AM PST, ID: 20874320

kaylanreilor:

I don't understand why your interested in DCOM. Is the sapi.dll supposed to used on another machine ?

02.12.2008 at 05:17AM PST, ID: 20874418

kaylanreilor:

Lauch OleView. In Object Classes expand "All Objects". Look for the object you want to set its properties. I've taken the example of SpCustomStreamClass.
Check the box "Use Surrogate Process" => will allowed this object to be instanciated from another process and this will be loaded in dllhost.

But really, I still don't understand why you want to register anything as a "DCOM" object.

godwindotnet:

Hi,
When I click the class, Its showing "Unsupported operation was attempted". Whatever the concept it is I am needing to run the component. I am stick to DCOM.

I installed sapi via "C:\WINDOWS\inf\sapi5.inf" but now it shows different errors.

Creating an instance of the COM component with CLSID {3BEE4890-4FE9-4A37-8C1E-5E7E12791C1F} from the IClassFactory failed due to the following error: 80004027.

Thanks Again Please help me.

                       
             RecognizerObj = new SpSharedRecognizer(); // error occurs here.
            stream = new SpCustomStreamClass();
            MyASRStream = new ASRStreamClass();
            objRecoContext = new SpSharedRecoContext();

>> I am stick to DCOM.
Sorry I am not stick to DCOM, whatever the concept it is What I need is a solution.

02.13.2008 at 05:35AM PST, ID: 20883974

kaylanreilor:

Your error means : The Component or application containing the component has been disabled.
I don't know what happenned on your machine but I would like to talk about this later if needed.

But anyway, did you exactly do what I've said in my post #20874311 ?
Open Visual Studio 2005 Command Prompt. Navigate to where sapi.dll is located.
Then execute this line:
tlbimp sapi.dll
=> tell me what's happen but the principal result is that the last line displayed should be "Type Library imported to SpeechLib.dll"

If you have a SpeechLib.dll generated on your machine you can then go back to the post #20865955.

godwindotnet:

Hi,
How can I get 20874311 post and 20865955 posts. I searched in experts-exchange it shows my current post only. Please Help me.

Regards,
R. Pandiarajan.

This is in THIS discussion, just above. I wrote :
Open Visual Studio 2005 Command Prompt. Navigate to where sapi.dll is located.
Then execute this line:
tlbimp sapi.dll
=> tell me what's happen but the principal result is that the last line displayed should be "Type Library imported to SpeechLib.dll"

Please, for the third time, just do that and tell me if you got the newly created SpeechLib.dll.

If yes, do what I post in #20865955 (in THIS thread) four days ago.

godwindotnet:

Thanks for response.
I tried by using tlbimp that didn't help me. Again the same problem. Actually I formatted and reinstalled everything , now it is working. I installed DirectX SDK, Platform SDK and then Speech SDK. That fixes this problem, But I don't know how it is working...!

R. Pandiarajan.
