I'm currently trying to use the following code to create an ApiClient connection
mGoogleApiClient = new GoogleApiClient.Builder(this)
.addApi(Wearable.API)
.addConnectionCallbacks(this)
.addOnConnectionFailedListener(this)
.build();
mGoogleApiClient.connect();
but in
#Override
public void onConnectionFailed(ConnectionResult connectionResult) {
Log.d(TAG, "Connection failed");
mGoogleApiClient.reconnect();
}
I'm getting this:
ConnectionResult{statusCode=SERVICE_INVALID, resolution=null}
If I'm reading correctly in the manual, this corresponds to the version of Play being wrong to begin with.
As such, am I missing something from properly connecting running the code on Glass or this is not supported yet?
To give you a rough idea of what I want to do, I want to implement this example.
Google Play Services is not supported on Glass at this time. This is currently being tracked as issue 176 in our issue tracker, so you can follow that for more info in the future.

Is there a way to enable change tracking for couple of entities programmatically? I could not find any api in Dataverse which can help to do this.
You cannot do that with webapi but you can definitely achieve this programatically.
you can either create console application or you can run code now plugin for xrmtoolbox and get this done.
Below code snippet for reference.
UpdateEntityRequest updateBankAccountRequest = new UpdateEntityRequest
{
Entity = BankAccountEntity,
ChangeTrackingEnabled = true //or false here
};
_serviceProxy.Execute(updateBankAccountRequest);
Microsoft docs for ChangeTrackingEnabled
There are a lot of examples on the internet on how to do this with the old JobHost, but none I can find with HostBuilder.
Thanks,
George
For now I didn't found detailed documentation on the new HostBuilder.
However looks like we could use this code to do it. You could find it on github.
.ConfigureServices(services =>
{
// add some sample services to demonstrate job class DI
services.AddSingleton<ISampleServiceA, SampleServiceA>();
services.AddSingleton<ISampleServiceB, SampleServiceB>();
}
And there is an answer about it, which uses the same service to implement it, you could try it.
I'm currently developing a simple application for querying/retrieving data on a PACS. I use DCMTK for this purpose, and a DCM4CHEE PACS as test server.
My goal is to implement simple C-FIND queries, and a C-MOVE retrieving system (coupled with a custom SCP to actually download the data).
To do so, I've created a CustomSCU class, that inherits the DCMTK DcmSCU class.
I first implemented a C-ECHO message, that worked great.
Then, I tried to implement C-FIND requesting, but I got the error "DIMSE No valid Presentation Context ID" (more on that in the next paragraph) from my application, but no other log from DCM4CHEE. I've then used the command tool findscu (from dcmtk) to see if there was some configuration issue but the tool just worked fine. So in order to implement my C-FIND request, I've read the source of findscu (here) and adapted it in my code (meaning that i'm not using DcmSCU::sendCFindRequest but the class DcmFindSU).
But now, i'm facing the same problem with C-MOVE request. My code is pretty straight-forward :
//transfer syntaxes
OFList<OFString> ts;
ts.push_back(UID_LittleEndianExplicitTransferSyntax);
ts.push_back(UID_BigEndianExplicitTransferSyntax);
ts.push_back(UID_LittleEndianImplicitTransferSyntax);
//sop class
OFString pc = UID_MOVEPatientRootQueryRetrieveInformationModel;
addPresentationContext(pc, ts);
DcmDataset query;
query.putAndInsertOFStringArray(DCM_QueryRetrieveLevel, "PATIENT");
query.putAndInsertOFStringArray(DCM_PatientID, <ThePatientId>);
OFCondition condition = sendMOVERequest(findPresentationContextID(pc, ""), getAETitle(), &query, nullptr);
return condition.good();
I've also tried using UID_MOVEStudyRootQueryRetrieveInformationModel instead of UID_MOVEPatientRootQueryRetrieveInformationModel, with the same result : my application shows the error
DIMSE No valid Presentation Context ID
As I understand, a presentation context is concatenation of one or more transfer syntax and one SOP class. I read that the problem could come from the PACS that won't accept my presentation contexts. To be sure, I used the movescu tool (from DCMTK). It worked, and I saw this in the logs from de server DCM4CHEE :
received AAssociatedRQ
pc-1 : as=<numbers>/Patient Root Q/R InfoModel = FIND
ts=<numbers>/Explicit VR Little Endian
ts=<numbers>/Explicit VR Big Endian
ts=<numbers>/Implicit VR Little Endian
That means that the movescu tool does a find before attempting an actual move ?
Therefore, I changed my application context creation with :
OFList<OFString> ts;
ts.push_back(UID_LittleEndianExplicitTransferSyntax);
ts.push_back(UID_BigEndianExplicitTransferSyntax);
ts.push_back(UID_LittleEndianImplicitTransferSyntax);
OFString pc1 = UID_FINDPatientRootQueryRetrieveInformationModel;
OFString pc = UID_MOVEPatientRootQueryRetrieveInformationModel;
addPresentationContext(pc1, ts);
addPresentationContext(pc, ts);
(also tried study root)
But this didn't do the trick.
The problem seems to lie on the client side, as findPresentationContextID(pc, ""); alwasy return 0, no matter what.
I don't feel like it's possible to adapt the code of the movescu tool, as it appears to be very complex and not adequat for simple retrieve operations.
I don't know what to try. I hope someone can help me understand what's going on. That's the last part of my application, as the storage SCP already works.
Regards
It looks like you are not negotiating the association with the PACS.
After adding the presentation contexts and before sending any command, the SCU must connect to the PACS and negotiate the PresentationContexts with DcmSCU::initNetwork and then DcmSCU::negotiateAssociation.
I am working on a blackberry application. I need to call soap webservices, but I am unable to do so, and am getting null as a response. Following is my code:
private static final String CONNECTION_PARAMS = ";deviceside=true";
SoapObject request = new SoapObject("http://service.action.com/",
"findActiveSecurities");
SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);
envelope.bodyOut = request;
HttpTransportBasicAuth ht =
new HttpTransportBasicAuth("http://myurl.com/ebclient/services/MobileClientService?wsdl"+CONNECTION_PARAMS,
"myusername",
"mypassword");
PropertyInfo propInfo=new PropertyInfo();
propInfo.type=PropertyInfo.INTEGER_CLASS;
//adding parameters
request.addProperty("arg0","NSE");
request.addProperty("arg1","0");
request.addProperty("arg2","100");
envelope.setOutputSoapObject(request);
try {
ht.call(SOAP_ACTION, envelope);
result = (SoapObject)envelope.getResponse();
System.out.println(result);
} catch (IOException e) {
e.printStackTrace();
} catch (XmlPullParserException e) {
e.printStackTrace();
}
I am getting null as a result.Please have a look at the code and help me to correct it.
Thanks in advance
Actually the problem was instead of passing 0 and 100 as String ...
request.addProperty("arg0","NSE");
request.addProperty("arg1","0");
request.addProperty("arg2","100");
I use
request.addProperty("arg0","NSE");
request.addProperty("arg1",new Integer(0));
request.addProperty("arg2",new Integer(1000));
also this link helped me.
also before asking this question I was facing some problem that the Simulator was not recognizing a Library. It shows error message something like "there is no library Ksoap2_j2me.jar" - resolved from this link.
Sorry for poor English but I think this can save time of some other developer.
It's hard to tell from what you're posted, but my guess is that you're having some kind of network problem. I'm guessing that you initialize result = null;, and then your call to ht.call() throws an IOException, leaving result null.
You're using ksoap2, which is a library written for generic J2ME clients. However, BlackBerry networking doesn't work exactly like all other J2ME platforms.
You are controlling the BlackBerry network transport with your connection params string, which is hardcoded:
private static final String CONNECTION_PARAMS = ";deviceside=true";
Unfortunately, this string suffix may not be right for all network conditions (or any, if you don't have device APN settings correct).
I think you have a couple choices:
1. Connection Suffix Strings
You can try dynamically choosing the right suffix string, depending on conditions when your app runs. This can allow the device, for example, to connect via Wi-Fi if it's available, or via BES if that's available. Developers new to BlackBerry may be surprised that app code needs to worry about this (read here for more, or watch this).
If you want to simply replace CONNECTION_PARAMS with a dynamic string, you might check out the implementation here.
2. ConnectionFactory
In OS 5.0, BlackBerry added the ConnectionFactory class, which was a big improvement over the old way of having to assemble connection strings. If you only need to support OS 5.0 and greater, you might choose to rewrite the code to use ConnectionFactory.
Since you have access to the ksoap source code, you could change it. It looks like the connection code is in ServiceConnectionMidp.java:
public ServiceConnectionMidp(String url) throws IOException {
connection = (HttpConnection) Connector.open(url, Connector.READ_WRITE, true);
}
Instead of attaching connection parameters to the url passed to this class, you could change the class to get the connection from a ConnectionFactory, customized to support the network transports you want.
Doing this means that if you ever want to update your code to use a new version of ksoap2, you'll need to make these modifications again. However, given the future of BlackBerry Java, that seems like a reasonable compromise to make.
I am new to C# and would be really grateful if someone could provide some insight on the following problem: I have written a c# app that gets the html content of a website, quite simply using a webclient. The problem is that if I run it for multiple websites I see that sometimes I get no results for some of them, like it was never connected to that website at that instance. I initially thought it was my internet connection but the same happened when I tried on a different wifi. It is worth mentioning that I have the same prob on another of my appcs when trying to connect to a webservice. My question is: does anybody know how can this be fixed? Does it have to do with the timeout time of something like that?
Thank you very much in advance
This is the code but it's not really an issue of coding:
var client = new WebClient();
try
{
var htmlcode = client.DownloadString(site);
int NumberOfTrues = Regex.Matches(htmlcode.ToLower(), key).Count;
}
catch (Exception)
{
messagebox.show("could not be loaded");
}
This was solved by defining the default proxy server in app config.
