Asp 5 ServerVariables - asp.net-core

I am in the progress of rewriting some code to work with ASP 5.
The old code does the following:
string Local_IP=Request.ServerVariables["LOCAL_ADDR"];
string HTTP_reverse_VIA = Request.ServerVariables["HTTP_REVERSE_VIA"];
How do I get the corresponding information from ASP 5?

HttpContext has the GetFeature method, using this method we can get feature information.
Here we are want to get Server Variables of IIS; check project.json "Microsoft.AspNet.Server.IIS" is used for running ASP.NET 5.
We have to use GetFeature of 'Microsoft.AspNet.Server.IIS' which contains Server variables feature. use the below code
var varibleFeature = Context.GetFeature<Microsoft.AspNet.Server.IIS.Features.IServerVariablesFeature>();
if (varibleFeature != null)
{
var valuesList = varibleFeature.ServerVariables;
//read through valuesList dictionary for Server Variables
}
Since I was running on IIS Express, it gave few variables but not the one mentioned in your question.
Please deploy it on IIS and explore more.

DiffGrams for .NET Core. We are upgrading our project to .NET Core 3.x so need to find the DiffGrams used in the previous version of .NET

We are upgrading our .NET 2.0 application to .NET Core 3.x there's a DiffGrams used to capture the Table field updates (before/after values) used for Auditing purpose. I have to achieve the similar in the .NET Core 3.x. I am not sure which one is the equivalent for .NET Core 3.x.
Could you anyone help me guide on this? Thank you.
DataSet.WriteXml/DataSet.ReadXml method applies to .NET Core 3.x.
The WriteXml method provides a way to write either data only, or both data and schema from a DataSet into an XML document.
private void WriteXmlToFile(DataSet thisDataSet)
{
if (thisDataSet == null) { return; }
// Create a file name to write to.
string filename = "XmlDoc.xml";
// Create the FileStream to write with.
System.IO.FileStream stream = new System.IO.FileStream
(filename, System.IO.FileMode.Create);
// Create an XmlTextWriter with the fileStream.
System.Xml.XmlTextWriter xmlWriter =
new System.Xml.XmlTextWriter(stream,
System.Text.Encoding.Unicode);
// Write to the file with the WriteXml method.
thisDataSet.WriteXml(xmlWriter, XmlWriteMode.DiffGram);
xmlWriter.Close();
}
The resultant XML code is rooted in the <diffgr:diffgram> node and contains up to three distinct data sections, as follows:
<diffgr:diffgram>
<MyDataSet>
:
</MyDataSet>
<diffgr:before>
:
</diffgr:before>
<diffgr:errors>
:
</diffgr:errors>
</diffgr:diffgram>

How to send parameters to Stimulsoft Report in Asp.Net Core 2.0?

I use Asp.net Core 2.0 Web Application.
I have a simple stimulsoft report file.
my report has a parameter Called #ID.
If I Use the report without parameter, it's working well, But When I send parameter to report, it's not working and report loaded empty.
my Code is:
var _Report = new Stimulsoft.Report.StiReport();
_Report.Load(#"C:\temp\report.mrt"); // load report
((StiSqlDatabase)_Report.Dictionary.Databases["Connection"]).ConnectionString = "new connectionString "; // change connection
_Report.DataSources["DataSource1"].Parameters["#ID"].ParameterValue = 5171; // set parameter value
_Report.Render();
Note: I use Asp.net Core version 2.0.
this code is working in asp.net well.
please help me.
thanks.
Wow!!!
solved.
I should use from Value Instead ParameterValue.
Like below:
_Report.DataSources["DataSource1"].Parameters["#ID"].Value = 5171;

JayData oData request with custom headers - ROUND 2

Few month back I was working on some Odata WCF project and I had some problems with parsing custom headers for token auth (apiKey).
At that time, being quite a noob (still am!), I posted this SO question: JayData oData request with custom headers
Today I am working on a new project with Jaydata Odata server and client library and this:
application.context.prepareRequest = function (r) {
r[0].headers['apikey'] = '123456';
};
was working fine till I had to do a MERGE request. I found out that somehow MERGE request was overriding my headers so I investigated further.
It appears at first that in the oDataProvider.js (~line 617) in the _saveRest method the headers are not inherited:
request = {
requestUri: this.providerConfiguration.oDataServiceHost + '/',
headers: {
MaxDataServiceVersion: this.providerConfiguration.maxDataServiceVersion
}
};
but a few lines later we get:
this.context.prepareRequest.call(this, requestData);
which "should" call my own prepareRequest, but doesnt... Instead it still points to:
//Line 11302 jaydata.js
prepareRequest: function () { },
which of course does... nothing! Funnilly enough, when you execute a simple GET the same code supposedly on the same context instance works and points to my prepareRequest override.
I can assert with enough confidence that somehow the context between GET/MERGE is not the same instance. I cant see, however, any place where the context instance is reassigned.
Has anyone got a clue?
PS: this is NOT a CORS issue. My OPTIONS is passing fine and manually feeding the headers in oDataProvider works.
More
I followed the lead on different context instances and found something interesting. calling EntitySet.save() ends up calling the EntityContext constructor. see trace:
$data.Class.define.constructor (jaydata.js:10015)
EntityContext (VM110762:7)
Service (VM110840:8)
storeToken.factory (jaydata.js:14166)
$data.Class.define._getContextPromise (jaydata.js:13725)
$data.Class.define._getStoreContext (jaydata.js:13700)
$data.Class.define._getStoreEntitySet (jaydata.js:13756)
$data.Class.define.EntityInstanceSave (jaydata.js:13837)
$data.Entity.$data.Class.define.save (jaydata.js:9774)
(anonymous function) (app.js:162) // My save()
That explains why I get two different instances...
Hack
Replacing the prepareRequest function direcly in the class definition works, but its ugly!
for now I can cope with this:
$data.EntityContext.prototype.prepareRequest = function (r) {
r[0].headers['apikey'] = '12345';
};
This works fine as long as you only need to talk to a single endpoint.
Final word based on my experience
As much as I like JayData, it is obvious that they created a monster and its getting out of their hands (poor forum, no community, half-documented,...).
I chose JD because I was lazy and wanted to keep working with my old WCF DataService. Switching to Web API seemed wrong or too much work for me.
Also as a .net dev I liked strong typing of my entities and the ability to work with a concrete model generated from the JD tools. However, in the end, I was adding confusion. Every time my server side model changed I had to fetch the new metadata and scaffold a new entityModel.
I ended up by switching to Web Api and migrated my data service layer to Breeze. And seriously! its a breeze to work with it!
The documentation is absolutely brilliant and here on S.O you can always count on Ward or Jay Tarband to reply with a very high amount of professionalism.
In the end I realize this should probably be more a wiki than a Question.....

Application name is not set. Call Builder#setApplicationName. error

Application: Connecting to BigQuery using BigQuery APIs for Java
Environment: Eclipse, Windows 7
My application was running fine until last night. I've made no changes (except for restarting my computer) and my code is suddenly giving me this error:
Application name is not set. Call Builder#setApplicationName.
Thankfully I had a tar'd version of my workspace from last night. I ran a folder compare and found the local_db.bin file was different. I deleted the existing local_db.bin file and tried to run the program again. And it worked fine!
Any idea why this might have happened?
Hopefully this will help anyone else who stumbles upon this issue.
Try this to set your application name
Drive service = new Drive.Builder(httpTransport, jsonFactory, null)
.setHttpRequestInitializer(credential)
.setApplicationName("Your app name")
.build();
If you are working with only Firebase Dynamic Links without Android or iOS app
Try this.
builder.setApplicationName(firebaseUtil.getApplicationName());
FirebaseUtil is custom class add keys and application name to this class
FirebaseDynamicLinks.Builder builder = new FirebaseDynamicLinks.Builder(
GoogleNetHttpTransport.newTrustedTransport(), JacksonFactory.getDefaultInstance(), null);
// initialize with api key
FirebaseDynamicLinksRequestInitializer firebaseDynamicLinksRequestInitializer = new FirebaseDynamicLinksRequestInitializer(
firebaseUtil.getFirebaseApiKey());
builder.setFirebaseDynamicLinksRequestInitializer(firebaseDynamicLinksRequestInitializer);
builder.setApplicationName(firebaseUtil.getApplicationName());
// build dynamic links
FirebaseDynamicLinks firebasedynamiclinks = builder.build();
// create Firebase Dynamic Links request
CreateShortDynamicLinkRequest createShortLinkRequest = new CreateShortDynamicLinkRequest();
createShortLinkRequest.setLongDynamicLink(firebaseUtil.getFirebaseUrlPrefix() + "?link=" + urlToShorten);
Suffix suffix = new Suffix();
suffix.setOption(firebaseUtil.getShortSuffixOption());
createShortLinkRequest.setSuffix(suffix);
// request short url
FirebaseDynamicLinks.ShortLinks.Create request = firebasedynamiclinks.shortLinks()
.create(createShortLinkRequest);
CreateShortDynamicLinkResponse createShortDynamicLinkResponse = request.execute();

How to read xml file from a relative path in RIA Service?

I am trying to read an XML file in RIA Service and I am getting the following error.
Load operation failed for query 'GetSummaryList'. Could not find a part of the path 'C:\WINDOWS\SYSTEM32\CoreResources\SumaryListDS.xml'.
I am using Silverlight 4 which is using RIA service. I am trying to read the SumaryListDS.xml located in the bin\CoreResources folder. But the application insted of looking for the file under bin\CoreResources, its trying to read it from C:\WINDOWS\SYSTEM32\CoreResources.
I am just wondering how to read a file using relative path in RIA Service with Silverlight front end?
Thanks,
Vinod
You should be able to use .. to go up one directory, such as ../CoreResources/GetSummaryList.xml
Here is how I resolved my problem. Its been implemented in one of the layers of business tier, which can be used by variety of clients (ASP.NET, Console App, Windows Client, Silverlight hosted inside ASP.NET). So when GetSummaryXml is called, previously it used to be
public DataSet GetSummaryXml()
{
var dsReport = new DataSet("Report");
var summaryListXmlPath = "CoreResources/SumaryListDS.xml";
dsReport.ReadXml(summaryListXmlPath);
return dsReport;
}
I started getting an error when I started consuming it in RIA Domain Service to be used by Silverlight 4 client.
ERROR:
Load operation failed for query
'GetSummaryList'. Could not find a
part of the path
'C:\WINDOWS\SYSTEM32\CoreResources\SumaryListDS.xml'.
But SumaryListDS.xml located in the bin\CoreResources, not WINDOWS\SYSTEM32\CoreResources
So I modified GetSummaryXml to...
public DataSet GetSummaryXml()
{
var dsReport = new DataSet("Report");
var currContext = HttpContext.Current;
var summaryListXmlPath = "CoreResources/SumaryListDS.xml";
if (currContext != null)
summaryListSchemaPath = currContext.Server.MapPath(#"../bin/" + summaryListXmlPath);
dsReport.ReadXml(summaryListXmlPath);
return dsReport;
}
And now its working fine. I am not sure if this is a perfect solution thou.
