Hi, I have a web API method and it returns IEnumerable. Cases is a wrapper class of "Proc" Class. I am consuming this web API from my client. If Proc has count 0, I can able to get data in my client from Web API. When Proc has value (greater than count 0), I get error "Unable to read data from the transport connection: An existing connection was forcibly closed by the remote host". I am working in VS 2017 and .Net Core 2.1 Please advise Cases.cs public partial class Cases { public CaseDetails() { CaseProcedures = new HashSet(); } public int Id { get; set; } public int UniqueNumber { get; set; } public HashSet Proc { get; set; } } Proc.cs public partial class Proc { public int Id { get; set; } public int CasesId { get; set; } }

Hi, I have an windows application. On button click, I call a service called ServiceA (ServiceA is in my local machine). From ServiceA's method, I hit database and retrieve some records. After retrieved, I call another WCF service called ServiceB (ServiceB is availabled in another machine within network). I have added ServiceB's proxy files in my ServiceA's project. endpoints and bindings are added in wwwroot\web.config. When I try to consume ServiceB's method, I am getting the following error. Could not connect to http://tde017:8080/AdapterService/AdapterService.svc. TCP error code 10013: An attempt was made to access a socket in a way forbidden by its access permissions 17.21.11.17:8080 Previously, it throws with the port number 80. I configured the another port 8080. Now error is throwing with 8080. But, If I consume the serviceB directly from my windows application, I am getting response. If I go through another service, I am getting error. I tried many scenarios. But, still I could not get solution. Any one help me on this.... Thanks in advance. Regards, Bala

Hi, I have tried to deploy my web application (VS2010 + C#) by adding the project output and building a msi setup. But, I want to do these steps through command prompt. Our command scripts will do all the stpes to deploy in server. That command prompt scripts should do the following things 1. Getting latest version of my solution 2. Adding web deployment project and adding project outputs there 3. Building and deploying in a server.. How to do these things thorugh command prompt only? Thanks in advance.

I am using Asp.Net 2.0. How can I avoid using back button after logged out from the page. Thanks in adv.

Hi All, I am working in Asp.Net 2.0 by code behind C#.Net. I want to show my report in crystal report (VS 2005). My report is getting opened, but, I could not get effect on page navigator symbol/ export symbol. If I click at the Next Page symbol, my page gets blank. The same thing is happening if I click any symbol of Business Objects. More over, at the top of the report, I am getting msg called "Object reference is not set to an instance" Pls help me to over come from this problem. Thanks in adv.

Balasubramanian K.

Actually, I pass 4 parameters only. If I pass the same into report directly, I can able to view the report. Through coding, I am trapped. However, you have spent your time for me. Thanks a lot.

Balasubramanian K.

It returns true. I am getting the business objects' symbols(Export, print, Page nagivator, etc.) also at my page followed by my error.

Balasubramanian K.

"Expression has been evaluated and has no value" is the value I am getting at immediate window of rptDoc.Load(Server.MapPath("Reports/STTCertificateAnnual1.rpt"));

Balasubramanian K.

All of my code lines are getting debug successfully without any error. But error has been shown at my page by debugging all of my lines. Thanks in adv.

Hi All, I am using Asp.Net 2.0 with C#, Crystal Reports(VS 2005). I am trying to open a report by passing 4 parameters but it gives an error called "Object reference not set to an instance of an object.". While I debug, I did not get err at any line. It goes smooth but finally it gives an error. Can you guide me?. Pls find below my code

crvSTT.RefreshReport();
ReportDocument rptDoc = new ReportDocument();
rptDoc.Load(Server.MapPath("Reports/STTCertificateAnnual1.rpt"));

ParameterFields paramFields = new ParameterFields();

ParameterField pfYear = new ParameterField();
ParameterField pfBACode = new ParameterField();
ParameterField pfFromClientCode = new ParameterField();
ParameterField pfToClientCode = new ParameterField();

pfBACode.ParameterFieldName = "pBACode";
ParameterDiscreteValue pdvBACode;
pdvBACode = new ParameterDiscreteValue();
pdvBACode.Value = strUserId;
pfBACode.CurrentValues.Add(pdvBACode);
paramFields.Add(pfBACode);

pfFromClientCode.ParameterFieldName = "pFromClientCode";
ParameterDiscreteValue pdvFromClientCode;
pdvFromClientCode = new ParameterDiscreteValue();
pdvFromClientCode.Value = txtFromCC.Text;
pfFromClientCode.CurrentValues.Add(pdvFromClientCode);
paramFields.Add(pfFromClientCode);

pfToClientCode.ParameterFieldName = "pToClientCode";
ParameterDiscreteValue pdvToClientCode;
pdvToClientCode = new ParameterDiscreteValue();
pdvToClientCode.Value = txtToCC.Text;
pfToClientCode.CurrentValues.Add(pdvToClientCode);
paramFields.Add(pfToClientCode);

pfYear.ParameterFieldName = "pYear";
ParameterDiscreteValue pdvYear;
pdvYear = new ParameterDiscreteValue();
pdvYear.Value = "Current";
pfYear.CurrentValues.Add(pdvYear);
paramFields.Add(pfYear);

crvSTT.ParameterFieldInfo = paramFields;
crvSTT.ReportSource = rp.tDoc;
crvSTT.DataBind();

Thanks in Adv.

"Expression has been evaluated and has no value" is the value I am getting at rptDoc.Load(Server.MapPath("Reports/STTCertificateAnnual1.rpt")); But the report is available in proper place. What I have to do to solve this?

Balasubramanian K.

"Object reference not set to an instance of an object." is the error I got at my page by came through all the steps of my codes.

Thanks in Adv :omg:

Balasubramanian K.

Yes. It is working fine now. Thanks

Balasubramanian K.

I solved this problem. I used waitForExit.
