We have implemeneted C-Store as part of Query Retrieve, that stores all involved SOP instances to the SCP. This is done asynchronous. For some reasons the SCP (Windows XP) does not accept the association at certain points.

My questions:
1. Is asynchronous storing of images advised?
2. Is there a limitation of connections to a SCP running Windows XP when using asynchronous C-store?

Are you using our high-level PACS Framework or our low-level DICOM (Leadtools.DicomNet namespace) methods? Also, what version of the SDK are you testing with?

If I'm understanding correctly, you're sending all of the images in one association without waiting for the CStore response. This isn't an industry standard practice, and by doing this, you'll face issues with third party PACS systems. Typically, you would need to create multiple parallel associations to store the images simultaneously.

Asynchronous mode of communication is supported with the SDK, but may not be currently supported with our high-level framework.

See the following methods:
DicomAssociate.SetAsynchronousOperations()
DicomAssociate.IsAsynchronousOperations
DicomAssociate.InvokedOperationsCount
DicomAssociate.PerformedOperationsCount

I'd like to test this out further here. Please send us a small sample project (not your entire application) which isolates this issue so that we can look into this matter further. Small sample projects are generally one or two button forms that easily illustrate the issue.

NOTE: If you are attaching a project or file to the forums...
1.) Zip the file(s) up.
2.) Make sure it is less than 5 MB.  If it is larger, please send an email to support@leadtools.com and we'll send you FTP instructions.
3.) Remove ANY AND ALL unlock codes/license files and LEADTOOLS DLLs.
4.) Do not click the preview button, the attachment will not show up when you post it.

If you do not wish to post your file(s) on the forum since they are publicly viewable, please send an email to support@leadtools.com and make sure that you include a link to this forum post.
