  <li>Added new OPC event handler to all OPC-enabled components: OnBeforeNewOPCData.&nbsp; 
  This event passes the index of the OPC item and the variant data value by reference 
  (pointer reference) so that you can modify or scale the value before it is passed 
  to the component and before the standard event handlers are called.</li>
  <li>Added independent Cursor and Legend data point value formatting to the Plot 
  Pack axis objects.&nbsp; Each channel is associated with a Y-Axis and X-Axis.&nbsp; 
  Each axis is responsible for specifying the formatting of displayed data for values 
  associated for that axis.&nbsp; This goes for channel data displayed in other 
  objects, such as in the cursor and/or legend objects.&nbsp; By default, all objects 
  display X and Y values formatted as shown in the respective axis.&nbsp; For example, 
  if the X-Axis is formatted as date/time &quot;hh:nn:ss&quot;, then X-values displayed in 
  the Data Cursor are displayed formatted the same way.&nbsp; You can now override 
  this default formatting, and specify that the formatting be different when displayed 
  in either the Legend or Data Cursor Objects. The following new properties in the 
  X and Y-Axis objects...<br>

  <li>Updated installer to support Delphi 7 VCL and CLX components.</li>
  <li>Upgraded Plot Pack to correctly display long labels in the X and Y-axes so 
  that they are not &quot;cropped&quot; when near the edge of the component.&nbsp; This has 
  resulted in a change in the layout of the plot component objects, particularly 
  the Legend and Label objects.&nbsp; Now, the Label object and Legend object top/bottom/left/right 
  margin properties are strictly interpreted.&nbsp; This will result in the gap 
  between the Legend and the Data View as well as Labels and the Data View shrinking 
  to be exactly the margin specified by the top/bottom/left/right margin properties.
  <br>
  <br>
  Since the default top/bottom/left/right margins for the Legend are set at a default 
  of one character, the margin between the Data View and the Legend will now be 
  exactly one character.&nbsp; Since the default top/bottom/left/right margins for 
  the Label is set at a default of zero characters, the margin between the Data 
  View and the label will now be exactly 0 characters (plus font specific kerning).&nbsp; 
  This means that with most fonts, there will be a kerning gap (extra space added 
  below the baseline to accommodate characters that are generally drawn below the 
  baseline such as &quot;j&quot; or &quot;g&quot;), but letters&nbsp; that go below the kerning baseline 
  will now touch the Data View.&nbsp; To fix this, we recommend setting the margin 
  nearest the Data View to 0.25 characters (or alternatively setting all margins 
  for all labels to 0.25 characters).&nbsp; This change should not affect most users 
  in a negative way, but will slightly change the visual layout of some objects.</li>
  <li>iObjectCanvas now supports loading images into a built-in image list that 
  can also stream into your form.&nbsp; You can also load image lists from resources 
  using name or ID.</li>
  <li>Added GetDisplayXToPixelsX and GetDisplayYToPixelsY to iObjectCanvas.&nbsp; 
  Allows conversion between the component&#39;s display units and pixels on the component.</li>
  <li>Added new iImageDisplay component.&nbsp; Allows loading of multiple bitmap 
  frames, and controllable animation framerate.</li>
  <li>Updated Plot Pack component backgrounds to support gradient colors.</li>
  <li>Added new iPipe component.&nbsp; Includes 3d straight pipe and animation capabilities.</li>
  <li>Added new iPipeJoint component. To be used with the iPipe component.</li>
  <li>Added new iIntegerOutput component.&nbsp; Similar to iAnalogOutput, but supports 
  Integer only output.&nbsp; Supports Integer, Hex, Binary, and Octal formatting 
  styles.</li>
  <li>Added new iScope Component.&nbsp; True Analog/Digital Oscilloscope component 
  with built-in Trigger.</li>
  <li>New VCL/CLX, ActiveX WinHelp, and ActiveX HTML Help for MSDN (Pre January 
  2002 Editioin) Files including many corrections.</li>
  <li>Added new iLCDMatrix component.&nbsp; Includes 5x7 built-in character font 
  for displaying 5x7 dot-matrix display text.&nbsp;&nbsp;&nbsp; Also supports loading 
  external character sets of custom size.&nbsp; Several additional 5x8 character 
  sets are included.&nbsp; An external font editor is available for download from 
  our website.</li>
  <li>Added new iMotor component.</li>

<h4>ActiveX and VCL/CLX Version 2.1.2 Service Pack 6</h4>
<h4>Bug Fixes:</h4>
<ol>
  <li>Fixed &quot;Interface Not Supported&quot; exception in Visual Basic.NET and C#.NET that 
  occurred with the Plot Pack. </li>
  <li>Fixed problem where popup dialogs and runtime property editors would block 
  other threads from accessing the component while they were visible.&nbsp; Unnecessary 
  Lock and Unlocks by these dialogs were removed.</li>
  <li>Redesigned the Iocomp Theme Panel component in the Iocomp Design-Time property 
  editors to fix a bug under Windows 95/98/ME operating systems when applying changes.&nbsp; 
  Nested panel components within the theme panel were causing conflicts with the 
  Windows API combo boxes that were used.</li>
  <li>Redesigned the Iocomp Theme Panel auto-centering code for compatibility under 
  CLX.</li>
  <li>Fixed bug in iModeComboBox VCL component where the OnChange and OnChangeUser 
  events would not fire under Delphi 4-5 and C++ Builder 4-5.</li>
  <li>Fixed bug in Plot Pack Annotations when used with logarithmic axes.&nbsp; 
  The annotation would size logarithmically instead of linearly when doing manual 
  sizing with the mouse at runtime.</li>
  <li>Fixed ActiveX compatibility issues with Microsoft Visual Studio.NET.&nbsp; 
  Components now successfully stream and function with managed VB.NET and C#.NET 
  applications.&nbsp; ActiveX components already were compatible with Visual C++.NET.&nbsp; 
  See the Iocomp ActiveX Release Notes for any issues with porting older Visual 
  Basic 5/6 applications to VB.NET using our ActiveX components.</li>
  <li>Fixed absolute positioning bug in Internet Explorer.&nbsp; Component would 
  always be positioned at the origin (upper left-hand corner) of the web page if 
  absolute positioning was used with our components.</li>
  <li>Fixed misspelling for default filename in the Plot Pack Save JPEG/BITMAP/Metafile 
  dialog.</li>
  <li>Limited DateTime format dates to years between 1400 to 9000.&nbsp; This resolves 
  zooming errors that occurred when trying to zoom past these limits.</li>
  <li>Fixed multiple pointer streaming issue in the ActiveX Gauge Components.&nbsp; 
  If multiple pointers were setup at Design-Time, they would not be streamed correctly 
  to the form. </li>
  <li>Fixed problem with Plot Pack zooming when using Logarithmic scales.</li>
  <li>Fixed Plot Pack Differential Interpolation drawing algorithm problem.&nbsp; 
  The last data point should draw to infinity.&nbsp; If the last data point went 
  out of view, the infinity line would incorrectly disappear.</li>
  <li>Fixed problem where an additional pointer would be added to our gauge components 
  every time you loaded the project in Visual Basic.</li>
  <li>Fixed Theme problem where width and height of preview component would be switched 
  if the orientation of the component was opposite of the default setting.</li>
  <li>Fixed GetBytes JPEG memory leak and speed issues.</li>
  <li>Fixed recursive painting bug when using stacked axes in the Plot Pack.&nbsp; 
  This only became obvious with large, viewable data sets.</li>
  <li>Fixed OPCItem browser limitation of 256 computers when browsing a Windows 
  computer domain.&nbsp; The limit has been upgraded to support approximately 1000 
  computers per domain when browsing.</li>
  <li>Fixed bug during development under Windows 95a/b where the component would 
  appear to be unlicensed.&nbsp; This did not affect deployed applications under 
  Windows 95a/b, only development.</li>
  <li>Fixed runtime property editor bug with plot pack when running under large 
  fonts.&nbsp; Form would not automatically scale properly to large fonts.</li>
  <li>Fixed memory leak in iKeyboard drawing algorithm.</li>
  <li>Corrected ActiveX sizing problem in RSView.</li>
  <li>Fixed iObjectCanvas OnClickObject event.&nbsp; The event handler was not firing 
  correctly.</li>
</ol>
<h4>New Features:</h4>
<ol>
  <li>Added to iPlotChannelCustom, DrawStartIndex and DrawStopIndex that inform 
  you of the data point indexes that are currently visible in the Data View.</li>
  <li>Added OnBeforeLoadProperties and OnAfterLoadProperties events added to Plot 
  Pack Components.</li>
  <li>Added Width, Height, Left, and Top properties for ActiveX containers that 
  do not provide these properties by default.&nbsp; These properties are specified 
  in pixels.&nbsp; If the container overrides these properties&nbsp; then the container 
  will be responsible for these properties.&nbsp; For example, Visual Basic overrides 
  these properties and replaces them with its own container properties.&nbsp; Its 
  container properties are specified in Twips by default and not in Pixels.</li>
  <li>Added UserCanAddRemoveChannels property.&nbsp; This property controls whether 
  the Add/Remove buttons are shown in the Runtime Property Editor.</li>
  <li>Added SaveAnnotationsToFile and LoadAnnotationsFromFile methods to the Plot 
  Pack Components.&nbsp; This method should be called after loading properties from 
  a file since the loading of properties clears out the entire control.</li>
