Hi, [:)]

I converted MyDicomNet.cpp of DicomMWL example in ClassLibrary folder in Medical Imaging Suite SDK v15 directory to object pascal code and have been testing it's functions in these days.

procedure OnReceiveAssociateAccept(hNet: HDICOMNET; hPDU: HDICOMPDU; pUserData: L_PVOID); stdcall;

...

   case FCommandType of

   MODALITY_WORKLIST_FIND:

CreateAndSetElement(hDS, TAG_SCHEDULED_PROCEDURE_STEP_START_DATE, VR_DA, Global.FSPSStartDate);
CreateAndSetElement(hDS, TAG_SCHEDULED_PROCEDURE_STEP_END_DATE,   VR_DA, Global.FSPSEndDate);

...

SendCFindRequest(
          nPresentationID,
          FUniqueID,
          UID_MODALITY_WORKLIST_FIND,
          COMMAND_PRIORITY_MEDIUM,
          hDS);

 

In above code, I just wanted to find worklist by querying START_DATE and END_DATE.

But,  if Global.FSPSStartDate is '07/05/2007'(Yesterday) and Global.FSPSEndDate is '07/06/2007'(Today) then I can't get any query results. I am using BUNNY test server, and
of course, there exists an worklist items of today and yesterday in it.

How can I solve this problem? Thanks a lot in advance.

In our demo for Query and Retrieve, we do a search based on a date range.  I have copied and pasted the code below:
This starts on line#756 from the file CFind.cs in the project CSDicomFindMoveDemo found in the directory \LEADTOOLS 15\Examples\DotNet\CS\DicomFindMoveDemo

               case FindType.Study:
               {
                  ds.Initialize(DicomClassType.StudyRootQueryStudy, DicomDataSetInitializeType.ExplicitVRLittleEndian);

                  Utils.SetTag(ds, DicomTagType.QueryRetrieveLevel, "STUDY");
                  Utils.SetTag(ds, DicomTagType.StudyInstanceUID, query.StudyInstanceUid);
                  Utils.SetTag(ds, DicomTagType.StudyID, query.StudyID);
                  Utils.SetTag(ds, DicomTagType.AccessionNumber, query.AccessionNo);
                  Utils.SetTag(ds, DicomTagType.PatientName, query.PatientName);
                  Utils.SetTag(ds, DicomTagType.PatientID, query.PatientID);

                  if(DateTime.Compare(query.StudyStartDate, DateTime.MinValue) != 0 &&
                     DateTime.Compare(query.StudyEndDate, DateTime.MinValue) != 0)
                  {
                     StringBuilder range = new StringBuilder();

                     range.Append(query.StudyStartDate.ToString("yyyyMMdd"));
                     range.Append("-");
                     range.Append(query.StudyEndDate.ToString("yyyyMMdd"));

                     Utils.SetTag(ds, DicomTagType.StudyDate, Encoding.UTF8.GetBytes(range.ToString()));
                  }
                  else if(DateTime.Compare(query.StudyStartDate, DateTime.MinValue) == 0 &&
                         DateTime.Compare(query.StudyEndDate, DateTime.MinValue) != 0)
                  {
                     StringBuilder range = new StringBuilder();

                     range.Append("-");
                     range.Append(query.StudyEndDate.ToString("yyyyMMdd"));
                     Utils.SetTag(ds, DicomTagType.StudyDate, Encoding.UTF8.GetBytes(range.ToString()));
                  }
                  else if(DateTime.Compare(query.StudyStartDate, DateTime.MinValue) != 0 &&
                         DateTime.Compare(query.StudyEndDate, DateTime.MinValue) == 0)
                  {
                     StringBuilder range = new StringBuilder();

                     range.Append(query.StudyStartDate.ToString("yyyyMMdd"));
                     range.Append("-");
                     Utils.SetTag(ds, DicomTagType.StudyDate, Encoding.UTF8.GetBytes(range.ToString()));
                  }
               }
               break;
