RS.exe subscribe report with parameters - vb.net

Question

I am trying to create dynamic report subscriptions through rs.exe. How ever I cannot get the parameters to work. The enddate value is data/time, so I think that might be causing it, but I do not know what to do about it. I have tried casting, but the error msg. stays the same.
rs.exe call:
C:\Program Files (x86)\Microsoft SQL Server\130\Tools\Binn>rs.exe -i C:\Users\me\Desktop\rss_gen\subs.rss -s "localhost/ReportserverT"
subs.rss file:
Public Sub Main()
rs.Credentials = System.Net.CredentialCache.DefaultCredentials
Dim desc As String = "Report description"
Dim eventType As String = "TimedSubscription"
Dim scheduleXml As String = "<ScheduleDefinition><StartDateTime>2017-12-08T15:00:00</StartDateTime><WeeklyRecurrence><WeeksInterval>1</WeeksInterval><DaysOfWeek><Thursday>True</Thursday></DaysOfWeek></WeeklyRecurrence></ScheduleDefinition>"
Dim parameters() As ParameterValue
' If you need setup parameters
Dim parameter As ParameterValue
parameter.Name = "enddate"
parameter.Value = "2017-12-30 10:03:01.250" 'this is date/time
parameters(0) = parameter
Dim matchData As String = scheduleXml
Dim returnValue As String
Dim reports() As String = { _
"/My Folder/report"}
For Each report As String In reports
returnValue = rs.CreateSubscription(report, parameters)
Console.WriteLine(returnValue)
Next
End Sub 'Main`enter code here`
Error msg:
C:\Users\mee\AppData\Local\Temp\11\dhexge0m.1.vb(43) : error BC30455:
Argument n ot specified for parameter 'Parameters' of 'Public Function
CreateSubscription(R eport As String, ExtensionSettings As

Let me teach you a trick to program in .Net and in general. It sounds simple, all you need to do is pass functions what they expect. Let me give you a simple example.
With this code I've got a similar error to you:
CS7036 There is no argument given that corresponds to the required formal parameter 'fileName' of 'FileInfo.FileInfo(string)'
The squiggle red line tells you where the problem is. If I type the opening bracket it will give me a tooltip with what it expects:
Ok it needs a string, so I declare a string and give it to the function as it expects:
So the problem you have is because you are not giving the CreateSubscription function the parameters it expects.
Argument not specified for parameter 'Parameters' of 'Public Function CreateSubscription
To fix it provide all the mandatory parameters to the ReportingService2005.CreateSubscription Method:
public static void Main()
{
ReportingService2005 rs = new ReportingService2005();
rs.Credentials = System.Net.CredentialCache.DefaultCredentials;
string report = "/SampleReports/Employee Sales Summary";
string desc = "Send email to anyone#microsoft.com";
string eventType = "TimedSubscription";
string scheduleXml = #"<ScheduleDefinition><StartDateTime>2003-02-24T09:00:00-08:00</StartDateTime><WeeklyRecurrence><WeeksInterval>1</WeeksInterval><DaysOfWeek><Monday>True</Monday></DaysOfWeek></WeeklyRecurrence></ScheduleDefinition>";
ParameterValue[] extensionParams = new ParameterValue[8];
extensionParams[0] = new ParameterValue();
extensionParams[0].Name = "TO";
extensionParams[0].Value = "dank#adventure-works.com";
extensionParams[1] = new ParameterValue();
extensionParams[1].Name = "ReplyTo";
extensionParams[1].Value = "reporting#adventure-works.com";
ParameterValue parameter = new ParameterValue();
parameter.Name = "EmpID";
parameter.Value = "38";
ParameterValue[] parameters = new ParameterValue[1];
parameters[0] = parameter;
string matchData = scheduleXml;
ExtensionSettings extSettings = new ExtensionSettings();
extSettings.ParameterValues = extensionParams;
extSettings.Extension = "Report Server Email";
try
{
rs.CreateSubscription(report, extSettings, desc, eventType, matchData, parameters);
}
catch (SoapException e)
{
Console.WriteLine(e.Detail.InnerXml.ToString());
}
}

As part of the 2005 report service for ms SQL, none of the parameters passed to CreateSubscription are optional. Please refer to the link and update the way you are calling the function. The error is clear, you are missing the parameters which is the last one. Look at the bottom of the page for an example.
