Hello All,
I have an ASP.Net web application hosted in NLB infrastructure with 2 web servers and 2 app servers. I have 3 web services running in the application server with windows authentication enabled. Other settings as follows
Anonymous authentication is disabled
Basic authentication is disabled
Digest authentication is disabled
ASP.NET Impersonation is disabled.
Windows authentication is enabled
Negotiate is on priority with both Negotiate, NTLM is enabled.
using custom identity : DOmain\UserID2
useAppPoolCredentials set to true
useKernelMode set to TRUE
Registered serviceprincipa1Names for CN-UserID2.CN-Users.DC-XX.DC-XXXX.DC-COM:
HTTP/AppServerName2 : 10443
HTTP/AppServerName1 : 10443
HTTP/AppServerName2 : 443
HTTP/AppServerName1 : 443
As per my observation, user encounter error 401 1 2148074254 when website access a specific webservice(let's say webservice 1) for the first time. When user access the same function again then there is no recurrence of 401 error.
Noticed the Start Mode was set to "On Demand" mode in app pool settings. Tried changing the Start Mode to "Always Running" and Idle Time-Out to "0" but still encountered the same error and the same pattern.

Greetings again.
As you can see from the code below, there are six input parameters and any one of those can be passed to display several rows of data from the database.
There is especially one called call_list_id.
When a value of call_list_id is passed, there are at least 15 records associated with it.
I can confirm this when I run it from SSMS.
However, I will pass same value through my app, only one record is displayed.
What is even more weird is that one record displays as soon as the page loads without even filtering with call_list_id value.
What am I doing wrong?
Many thanks in advance

It may load 15 rows, but each row overwrites the data from the previous row, so only the last row will be displayed.
You need to use a control which is capable of displaying more than one row - for example, the ListView control[^].

Thank you very much Richard for the prompt response.
From the ListView example though, there is only one parameter which is color:
sp:ControlParameter ControlID="ColorList" Name="Color"
I have several parameters. Do I try listing those parameters like:
sp:ControlParameter ControlID="@uuid" Name="uuid", ControlID="@callerlist" Name="call_list_id"...

Awesome.
Thank you very much for your help as always.

Or you can use this as a model
Create your model, this is off the top of my head, I forget how to do this in VB
Public class RecordModel
public property PhoneNumber As String
public property CallerId As String
End Class
Then in the database function, call the function to return a list of the model. After you get your list formatted for Linq, then you can fabricate your HTML elements in a for each loop.
Public Shared DatabaseFunction() As List(Of RecordModel)
Dim Results as New List(Of RecordModel)
While dr.Read()
Results.Add(New RecordModel() With {
PhoneNumber = dr("phone_number"),
CallerId = dr("callerid")
}
End While
Return Results
End Function
This will return the results. If the results if any exist
Dim results = DatabaseFunction()
If results.Any() Then
For Each result in results
'Do something
Next
End If

Oh great.
This seems much easier since all the samples of data source I have seen so far seems very complicated.
I have not done it with more than one parameter before and have not done via binding as the Great Richard suggested.
I have been playing around with Richard's suggestion but I will try this and hopefully, I can get it to work.
Thanks a lot for your help.

I stopped using binding over a decade ago. When they break you have to fix them.
The internet is flooded with outdated information and tutorials and really needs to be cleaned up.
The example I gave you is home grown, sort of a natural evolution I leaned towards and not really in any tutorials. Notice how simple the code is. Using Jet Brains Ultimate Refactor, I learned that I don't have to fully Dim an object and can use Dim like var in c#, or like var or let in TypeScript. Once you carefully craft a good model, it can reused over and over with ease. Then you can use Linq to populate, manipulate, or spawn more copies of the model.
If you start coding like this, then that will pave the way for you to use MVC, then .Net Core, and Angular/React. But it's all in how you craft your model. And a model can be a single record, or a list or records. Or it can be a record with a list of records inside. Create a model, populate it with data, then use the model. Pass the model around to what ever needs it.
The example is really modern coding pratices taken backwards to web or win forms.
Give it a try, it's worth the investment in time.
See yah around Sam!

Your code seemed really labor intensive. Maybe that's why Richard suggested binding.
Here's a sample to give you an idea of how you can condense and shorten your code. This code has been Jet Brains Ultimate Refactored to be as small as possible. You can feed as many parameters you want. This passes a model into the function, and returns another model as the result.
You just need to change the connection type and string and parameter type for whatever db server technology your using.
Private Shared Function Get_FI_Customer_SAInvoices(
ByVal sFi As FreeInvoice) As List(Of InvoiceIndex)
Dim pResults As New List(Of InvoiceIndex)
Dim dbPath = RegistryShared.Read_HKCU_DataPath()
Dim connString As String = "Provider=" & My.Resources.DBProviderOLE & "; Data Source=" & dbPath & "; Extended Properties=dBASE IV"
Const queryString As String =
"SELECT " &
" h.FINVNO " &
"FROM ARADD01H.dbf h" &
" WHERE h.FCOMPANY = @FCOMPANY " &
" AND h.FCITY = @FCITY " &
" AND h.FZIP = @FZIP " &
"UNION ALL " &
"SELECT " &
" v.FINVNO " &
"FROM ARADD01.dbf v" &
" WHERE v.FCOMPANY = @FCOMPANY " &
" AND v.FCITY = @FCITY " &
" AND v.FZIP = @FZIP "
Using connection As New OleDbConnection(connString)
Using command As New OleDbCommand(queryString, connection)
command.Parameters.Add(New OleDbParameter("@FCOMPANY", OleDbType.VarChar)).Value = sFi.FCUSTOMER_NAME
command.Parameters.Add(New OleDbParameter("@FCITY", OleDbType.VarChar)).Value = sFi.FADDRESS.City
command.Parameters.Add(New OleDbParameter("@FZIP", OleDbType.VarChar)).Value = sFi.FADDRESS.PostalCode
Try
connection.Open()
Using reader As OleDbDataReader = command.ExecuteReader()
While reader.Read()
If Not reader.IsDBNull(0) Then
pResults.Add(New InvoiceIndex() With {
.InvoiceNumber = reader.GetValue(0),
.InvoiceDate = DateTime.Now
})
End If
End While
reader.Close()
End Using
Catch ex As Exception
ErrorLogging.NLog_Exception(ex, "Db_FI_CustomerAdvByDate")
Finally
connection.Close()
End Try
End Using
End Using
Return pResults
End Function

Hello,
Still having issues with the code from @jkirkerx. It is me, not the code, I am sure.
So, I decided to go the Richard route by switching back to binding to ListView datasource.
However, the code is not giving an error but when enter a vaue say for Caller List and click "Generate Report", nothing happens.
I just flickers for a second.
I know I am missing something critical but have been looking at this now for two days with no success.
I have decided to post some relevant HTML markup and some VB. Hopefuly, you guys can put me out of my misery.
Thank you very much.

Well the code I gave you is concept code, and not actual code.
To perfect my code, you have to do one step at a time.
So the first step would be to write the database code. And confirm that the proper data is returned in the model that you designed.
Once confirmed, you can move to the next step, which is to plug the code into your page code behind and reconfirm that the data model is still intact.
The last step would be to do a small sample in HTML, to confirm that you understand how to transfer the model from the code behind to the asp.net web form.
But this should be the same process as what Richard suggested.
What I do sometimes, is startup a new project or open a test project on a really small scale, and isolate the new code in a fresh environment. Most times it works correctly, which tells me that some other code is the problem.
I totally get the frustration. You don't know how bad I needed help with a project that I just could not figure out, and knew posting here would not help. I wished someone could of done a remote terminal on my project. But using a test project and plugging the code in 1 section at a time solved it for me.
I haven't work with web forms in over 4 years now. I would create a new form on a smaller scale, and work with 1 or 2 columns first and get that working. Then expand a couple columns at a time. It might be a miss typed column name or wrong data type and you got a silent crash.

Ok thank you so much for your encouragement.
Can you please explain this code just a bit mor.
I see that you are passing one param InvoiceIndex to your function.
But I also see three other variables that are part of the WHERE predicate.
I understand the variables are part of the search filters but I am a bit confused by them.

I didn't go back and delete the extra parameters. I thought I might need them to narrow down the customer in case of a duplicate.
I passed a model into the database function, and returned a model out of the database function.
So I made a model called "Invoice", then called a database function to populate the Invoice.
Then passed the "Invoice" model to another database function to get the rest of the invoice data.
I kept everything in models because it was just easier to do and less code to write. Rather than Dim more space, I just used the existing space I already made. I'm just populating the model, so I can pass it to the presentation layer and consume it.
You just seem to be having trouble at an unknown point and need to isolate the problem.
So you can write code to get the data, package it and confirm it.
Then write fake data and pass it to the presentation layer, or your code behind and the web form to confirm that.
And you should see your mistake.

I am still working on this issue but I have made good progress.
Right now, I am using GridView control which seems to be displaying more than one, several rows as a matter of fact.
My issue now is with embedded query.
There are 6 input parameters and a user can search with one or more at same time.
The query is not results based on input parameter.
For instance, if I select an item from the call_type dropdownList, I expect results based on the selected item from the dropdownList.
The query is not doing that. It is displaying ALL the records.
Same is the case with the rest of the parameters; the filtering is not working and I believe it has to do with the WHERE clauses in the query.
Can you please, please help?

I have an OData api and I wanna have a client side software to send request to this api and recieve answer. I used simple odata client but it gives me the answer in dictionary. I need the answer in object. Some people told me to use microsoft-odata-client and I search for it and I cannot fined any good answer for my problem. Anybody can help me?

According to the documentation, you should be able to feed the API a JSON string and receive one back. The JSON returned should be able to be cast to your model being Linq capable.
Actions and Functions in OData v4 Using ASP.NET Web API 2.2 | Microsoft Docs
Here is a sample Http Response header in the documentation. The returned data is in JSON format.
HTTP/1.1 200 OK
Content-Type: application/json; odata.metadata=minimal; odata.streaming=true
OData-Version: 4.0
Date: Sat, 28 Jun 2014 00:44:07 GMT
Content-Length: 85
{
"@odata.context":"http://localhost:38479/$metadata#Edm.Decimal","value":50.00
}
This is simple JSON. It may look like a dictionary but it's not. It's similar to YAML as well.
"@odata.context":"http://localhost:38479/$metadata#Edm.Decimal",
"value":50.00
You can test with Postman; send a request and inspect the response in raw format to confirm if it's your code or the API result.
The Basics of Using Postman for API Testing - YouTube
But I think your just mistaking this for Dictionary, because I can't see a dictionary as being capable of HTTP transport.
Now you need to make a model of the result to convert the JSON result. or use var result = callapi();

Hi
I have an existing class that sits in a library project that is used natively for handling data object instances and also serialized/deserialized for use with json, xml and datasets. Changing the class looks to be tricky without compromising other projects.
I'm trying to put a SOAP wrapper around some of the class logic but running into problems because the class has multiple Subclasses with the same name.

End Class
Public Class ProduceOrder
Public Class ResponseSet

Public Property TransactSucceed As Boolean
Public Property TransactCode As String
Public Property TransactDescription As String
Public Property StaffID As String
Public Property PurchaseOrder As String
End Class
End Class
End Class
End Class
I've been looking for solutions but so far I haven't found anything that has enabled me to use my existing class without alteration.
Does anyone know of any tricks that can be done in the ASMX to make it work?

I was going to answer this a couple of days ago when I was compiling; sorry about that. Had to test it.
You really just have a bad design and should change it. If your using this for soap you should decorate the class with serializable, so the data sent back to the client can be encoded.
I would of wrote it like this to make ResponseSet reusable.
Public Class DataModel
[Serializable()]
Public Class HardwareOrder
Public Class ResponseSet
Public Property TpxID As String
Public Property ResponseHeader As List(Of ResponseHeaderRow)
End Class
End Class
[Serializable()]
Public Class ProduceOrder
Public Class ResponseSet
Public Property StaffID As String
Public Property ResponseHeader As List(Of ResponseHeaderRow)
End Class
End Class
[Serializable()]
Public Class ResponseHeaderRow
Public Property TransactSucceed As Boolean
Public Property TransactCode As String
Public Property TransactDescription As String
Public Property TransactionReference As String
End Class
End Class
Or perhaps add a property to the ResponseHeader called ID, a generic name and drop your property of TpxId. But if you do that then there is no need to have HardwareOrder and ProduceOrder because they become the same model. Technically this can just become
[Serializable()]
Public Class Order
Public Property Id As String
Public Property TransactSucceed As Boolean
Public Property TransactCode As String
Public Property TransactDescription As String
Public Property TransactionReference As String
End Class

Hi Jkirkerx
Thanks for your posting. I tried it the code compiles fine but the same error I described earlier arises from the asmx at runtime
Error
Types 'Library.DataModel.HardwareOrder.ResponseSet' and 'Library.DataModel.ProduceOrder.ResponseSet' both use the XML type name, 'ResponseSet', from namespace 'http://MyTest.com/'. Use XML attributes to specify a unique XML name and/or namespace for the type.
When serializing to xml or json the class works fine but in SOAP things start to get a little ugly.
I found a solution that makes it work by adding the following XmlElement tags to the routines.
<WebMethod()>
Public Function SubmitHardwareOrder(<XmlElement("Parameters", Namespace:="http://MyTest.com/HardwareOrder.Parameters")> Parameters As DataModel.HardwareOrder.Parameters) As XmlElement("ResponseSet", Namespace:="http://MyTest.com/HardwareOrder.ResponseSet")> DataModel.HardwareOrder.ResponseSet
End Function
<WebMethod()>
Public Function SubmitProduceOrder(<XmlElement("Parameters", Namespace:="http://MyTest.com/ProduceOrder.Parameters")> Parameters As DataModel.ProduceOrder.Parameters) As XmlElement("ResponseSet", Namespace:="http://MyTest.com/ProduceOrder.ResponseSet")> DataModel.ProduceOrder.ResponseSet
End Function
I note that yes the above makes it work but its not beautiful because when you generate your web reference in visual studio the generated class does not have levels eg not not do this "DataModel.ProduceOrder.ResponseSet" instead its just "ResponseSet" and so next time it sees another class called "ResponseSet" it renames it to "ResponseSet1" and next time "ResponseSet2" and so on. So if you are working of a large complicated namespace/class with many levels the web references created wont be overly intuitive if naming is not unique.
Clearly SOAP (Simple Object Access Protocol) is just that simple and this endeavor hits it's limitations bang on.
The foreseeable options are
-consume the webservice as per my above example with the inconvenience of none intuitive naming
-modify the class or create a separate duplicated class just for SOAP webservice
-use SOAP differently with passing/returning literals/datasets not strictly working of object model
-modify or build the wsdl class manually (this is the biggest time waster! I stay well away from wsdls that dont work as is especially if not generated by visual studio)
-just use xml or json and stream the data back via a handler
-use something else WCF?

I wrote mine like this, but used serialized classes and not actual XML
Then tested it calling the API in the browser, and getting that white and blue page that shows the all the WSDL services.
I remember seeing my class outputted on the screen, but can't remember if it was XML. But I wrote a Win App to call this web service and it worked really well.
<WebMethod(EnableSession:=True)>
Public Function customers_load(
ByVal CustomerRequest As ws_customers_Request) As ws_customers_Response
Dim customer As New ws_customers_Response
Dim customerList As List(Of ws_customers_list) = Nothing
Dim dwXCode As Integer = crm_ef_login.administrator_Login(
CustomerRequest.Credentials_Key,
CustomerRequest.Credentials_Password
)
If (0 = dwXCode) Then
If CustomerRequest.PageIndex = 0 Then CustomerRequest.PageIndex = 1
If CustomerRequest.PageSize = 0 Then CustomerRequest.PageSize = 25
Dim m_count As Integer = crm_ws_ef_customers.customers_Load(
CustomerRequest.PageIndex,
CustomerRequest.PageSize,
customerList
)
If (m_count > 0) Then
customer.response_Code = "OK"
customer.response_Text = m_count & " subscribers have loaded successfully"
customer.customerList = customerList
Else
customer.response_Code = "E001"
customer.response_Text = "No subscribers exist in the database"
customer.customerList = customerList
End If
Else
customer.response_Code = "E000"
customer.response_Text = "Failed Authentication"
customer.customerList = Nothing
End If

Hi,
Want to develop a software by which view and print the sql data by searching data by specific name , date and time. Can anyone guide me ?

Hello,
I am trying to share a few API's between multiple sites on the same server (IIS 8.5).
In a simple architecture, I would have each site on its own port, and each API on its own port, with the sites pointing to the API's they need.
Unfortunately, we have a restriction that forces us to have the actual API's "under" the main site, by using "add application" in IIS, and using aliases for each API.
This works fine actually.
What I would like to now is to have other sites use the same API's, also by having aliases, but without physically duplicating the API's either on disk, or even in memory.
Put simply, it looks like this:
localhost:1000/index.html = site1
localhost:1000/aliasAPI1/… = api1
localhost:1000/aliasAPI2/… = api2
…
and I would like:
localhost:2000/index.html = site2
localhost:2000/aliasAPI1/… = api1 = same as on site 1, in the same physical folder
localhost:2000/aliasAPI2/… = api2 = same as on site 1, in the same physical folder
The reason being that site 1 is fully intranet, and site 2 will be visible from the outside world via junctions created somewhere else on the network, and where we want to enable only 1 port to reach site 2.
I actually made a test simply by adding applications under site 2, and pointing physically to the same API folders, and it works, but it shows that the API's are ran twice in memory.
Tried both in the same application pool, and in separate pools.
Is there a way to really share the API's in a configuration like this one ?
I've Googled the issue.. but couldn't find anything relevant 
Any help would be appreciated 
Fred
