registering uccapi

[kumarnitesh]

I have an application which need to start the audio/video settings on a button click. I have written code for that: ************start of code********************************************** HRESULT hr = CoInitialize(0); if (FAILED(hr))//CoInitialize failed return hr; //Obtain a pointer to the IUccPlatform interface //by way of the cocreatable UccPlatform class. CComPtr <IUccPlatform> pIUccPlatform; hr = CoCreateInstance ( __uuidof(UccPlatform), NULL, CLSCTX_INPROC_SERVER, __uuidof(IUccPlatform), (LPVOID *)&pIUccPlatform ); if (FAILED(hr)) { AfxMessageBox(IDS_STR_ERROR_COCREATE_INSTANCE); return hr; } CComBSTR bstrAppName = _T("application"); hr = pIUccPlatform->Initialize( bstrAppName); if (FAILED(hr)) { AfxMessageBox (IDS_STR_ERROR_INITIALIZE); return false; //device settings } CComPtr<IUccMediaDeviceSettings> spMediaDeviceSettingsPtr; pIUccPlatform->QueryInterface( &spMediaDeviceSettingsPtr ); spMediaDeviceSettingsPtr->InvokeTuningWizard((OAHWND)theApp.m_pMainWnd->m_hWnd, UCCTWP_AUDIO | UCCTWP_AUDIO_NONPRIVATE | UCCTWP_AUDIO_NOTIFICATION); //AfxMessageBox(IDS_STR_ERROR_INVOKE_TUNING_WIZARD); pIUccPlatform->Shutdown(); *****************End of Code************************ and as I know we have to add the three dlls(UCCAPIRES.dll,UccApi.dll,RTMPLTFM.dll) in application project, I have done that and I also got success in that. But when I run my application on other system after clicking button to start the audio/video settings I got an error message "Error CoCreateInstance ". If any idea then please share. Configuration for apllication is WindowsXp C++ .net2005
