Dicom server not receiving the "C-STORE" information

Hello,
We are developping an "SCP" sofware based on "Medical Imaging suite v15"
We are trying to learn about this component by reading help file and exploring the sample projects, such as "CSDicomServerDemo" project.
We plan to make our own software based on this sample.
Our software doesn't work fine : we are facing some problems with the "OnReceiveData" Event

---
protected override void OnReceiveData(byte presentationID, DicomDataSet cs, DicomDataSet ds)
{
if(server.SaveCSReceived && cs != null)
{
server.LogCS(this, cs)\\;
}
}

---

When we run in debug mode the "CSDicomServerDemo" project provided as sample project by leadtools, "cs.InformationClass"
property is set to "Cstore" when receiving data

When we run in debug mode our project, "cs.InformationClass" property is set to "undefined" when receiving data.

We are using the same software to send the dicom file (we use the sample software provided by leadtools : DicomStr_original.exe

We have made so much debbuging processes without any success. We try to solve this problem for several days.

Somebody in the leadtools suport team told us to check about properties not well initialized (a property shoul be "false" ) but I don't know if it is a server or a client property and have no more information about that...

Is there something usual we should have missed, for exemple Before the "SendAssociateAccept" method ?

Thank you for your help.

We have included in our project the "scp" and "base" class provided in the samp "CSDicomServerDemo" directly, without any modifications.
Is there a "client" well known property that can be the problem ?

Any help welcome ...

A little up to have some help on this problem...

In the software we have made, the "OnReceiveData" event is raised with, as parameter, "cs.InformationCommand=undifined" and "ds=null". How is it possible to get an OnReceiveData, raised by leadtools assembly, with these parameters, when sending, with leadtools sample program "DicomStr_Original.exe" a dicom file that contains data

Is it because the "Clients" collection is not well initialized? Becaus of a constructor not made in client or server class ?

protected override void OnReceiveData(byte presentationID, DicomDataSet cs, DicomDataSet ds)
{
if(server.SaveCSReceived && cs != null)
{
server.LogCS(this, cs);
}
}

We really need help for this problem : we have search for a solution so many times...

Thank you

Do we have to pay leadtools to have some help ?
Can a support team member tell us what to do to get a solution ?

I think it's not too hard for thoose who developped the samples to find our problem, that might be a very simple problem.

We don't know what to do...

If you need immediate assistance, please send a message to support@leadtools.com instead of posting to the forums.
We answer forum post when we can, but we always reply to support emails.

With your issue there are many reasons you are not getting the OnReceiveData event.  You need to start debugging each step towards this event.  For instance, first make sure you are getting an OnConnect event.  Make sure you have the CallingAE and CalledAE parameters correct.  Make sure you're specifiying the IP Address of the correct machine.  Make sure the port#'s are correct.

Make sure you're accepting the connection, and associating the connection.  Only after you have done all this will you then be able to process a C-Request.

If all else fails, make sure you OS's firewall is not blocking your application from listening for connections. 

Thank you for sending the project. We have found the issue. In your ServerConnection class's constructor you are calling the base class DicomNet constructor base(null, DicomSecurityMode.None, false)

When you use this constructor you must also call DicomNet::Initialize to initialize the object with more security options. However, in your code you were not doing this.

Add this to your code or use the other constructor and this should resolve the issue
