Loading a Data Set (C#)

Take the following steps to start a project and to add some code that loads a DICOM Data Set and prints information about the data set:

1.	Start Visual Studio .NET.
2.	Create new Windows Application C# project.
3.	Add the LEAD COM Objects to your project.
	On the Tools pull-down menu, use the Add/Remove Toolbox Items... option, select the COM Components Tab, then select the LEAD Raster View Control (14.5).
	On the Project pull-down menu, use the Add Reference... option, select the COM Tab, then select the following: LEAD Raster Object Library (14.5) LEAD Raster Variant Object Library (14.5 LEAD Raster Process Object Library (14.5) LEAD Raster IO Object Library (14.5) LEAD DICOM Kernel COM Object Library (14.5) LEAD DICOM DS COM Object Library (14.5).
4.	Select the LEAD Raster View Control, then add the control to your main form.
5.	Add a button to your form and name it as follows:
	Name	Text
	LoadImage	Load Image
6.	Add the following initialization code to the main form's Load event handler. In online help, you can use the Edit pull-down menu to copy the block of code.

//class data-members

private LTDICLib.LEADDicomDS LEADDICOM1 = new LTDICLib.LEADDicomDSClass();
private void Form1_Load(object sender, System.EventArgs e)
{
   //Unlock DICOM support.
   //Note that this is a sample key, which will not work in your toolkit.
   LTDicomKernelLib.LEADDicomFactory Factory = new LTDicomKernelLib.LEADDicomFactory();
   LTDicomKernelLib.LEADDicomKernel DicomKernel = null;
   string szLic = null;
   szLic = "LEADTOOLS OCX Copyright (c) 1991-2005 LEAD Technologies, Inc.";
   DicomKernel = (LTDicomKernelLib.LEADDicomKernel)Factory.CreateObject("LEADDicomKernel.LEADDicomKernel", szLic); LEADDICOM1 = (LTDICLib.LEADDicomDS) Factory.CreateObject("LEADDicomDS.LEADDicomDS", szLic);
   DicomKernel.UnlockSupport((short)LTDicomKernelLib.DicomSupportLockConstants.L_SUPPORT_MEDICAL, "TestKey");
}

7.	Code the LoadImage button's click procedure as follows:

private void LoadImage_Click(object eventSender, System.EventArgs eventArgs)
{
   short nRet = 0;
   short lCount = 0;
   bool result = false;
   LEADDICOM1.EnableMethodErrors = false;
   nRet = LEADDICOM1.LoadDS("D:\\lead14\\dist\\images\\dicom\\image1.dic", 0);
   if (nRet != (short)LTDicomKernelLib.DicomErrorCodes.DICOM_SUCCESS)
      MessageBox.Show("Error " + System.Convert.ToString(nRet) + " loading file!");
   lCount = (short)LEADDICOM1.GetModuleCount(); LEADDICOM1.FindIndexModule(0);
   result = LEADDICOM1.SetCurrentElement(LEADDICOM1.get_CurrentModule().get_Element(0).hElement);
   if (result == true)
      MessageBox.Show("There are " + System.Convert.ToString(lCount) + " modules in this data set." + ('\r') + "The first module has " + System.Convert.ToString(LEADDICOM1.get_CurrentModule().ElementCount) + " elements." + ('\r') + "The first element has: " + ('\r') + "Tag number:" + System.Convert.ToString(LEADDICOM1.get_CurrentElement().Tag, 16).ToUpper() + ('\r') + "VR: " + System.Convert.ToString(LEADDICOM1.get_CurrentElement().VR, 16).ToUpper());
   LEADDICOM1.EnableMethodErrors = true;
}

8.	Run your program to test it.
9.	Save the project to use as a starting point for other tasks in this tutorial.
