ChartView.Images Method (ExOrgChart)

The user can add images at design time, by drag and drop files to combo's image holder. The ImageSize property defines the size (width/height) of the icons within the control's Images collection. Use the ReplaceIcon method to add, remove or clear icons in the control's images collection. Use the Image property to assign an icon to a node. Use the Picture property to load a picture to a node.

The following VB sample uses the Microsoft Image List control:

ChartView1.Images ImageList1.hImageList

The following VB sample loads icons and pictures using the BASE64 encoded strings:

Run the sample and you get:

The following C++ sample loads a collection of icons from a BASE64 encoded string:

m_chartview.GetRoot().SetImage( 1 );

The following C++ sample loads the system's image list ( used by Windows Explorer ):

SHFILEINFO sfi; ZeroMemory( &sfi, sizeof(sfi) );
m_chartView.Images( COleVariant( (long)SHGetFileInfo(_T("C:\\"),  0, &sfi, sizeof (SHFILEINFO), SHGFI_SMALLICON | SHGFI_SYSICONINDEX  ) ) );

If you are using the CImageList class, you should use the HIMAGELIST operator of the CImageList class, to pass to the Images method like described:

m_chartView.Images( COleVariant( long( pImageList->operator HIMAGELIST() ) ) );

		Type	Description
		Handle as Variant	The Handle parameter can be: A string expression that specifies the ICO file to add. The ICO file format is an image file format for computer icons in Microsoft Windows. ICO files contain one or more small images at multiple sizes and color depths, such that they may be scaled appropriately. For instance, Images("c:\temp\copy.ico") method adds the sync.ico file to the control's Images collection (string, loads the icon using its path) A string expression that indicates the BASE64 encoded string that holds the icons list. Use the Exontrol's ExImages tool to save/load your icons as BASE64 encoded format. In this case the string may begin with "gBJJ..." (string, loads icons using base64 encoded string) A reference to a Microsoft ImageList control (mscomctl.ocx, MSComctlLib.ImageList type) that holds the icons to add (object, loads icons from a Microsoft ImageList control) A reference to a Picture (IPictureDisp implementation) that holds the icon to add. For instance, the VB's LoadPicture (Function LoadPicture([FileName], [Size], [ColorDepth], [X], [Y]) As IPictureDisp) or LoadResPicture (Function LoadResPicture(id, restype As Integer) As IPictureDisp) returns a picture object (object, loads icon from a Picture object) A long expression that identifies a handle to an Image List Control ( the Handle should be of HIMAGELIST type ). On 64-bit platforms, the Handle parameter must be a Variant of LongLong / LONG_PTR data type ( signed 64-bit (8-byte) integers ), saved under llVal field, as VT_I8 type. The LONGLONG / LONG_PTR is __int64, a 64-bit integer. For instance, in C++ you can use as Images( COleVariant( (LONG_PTR)hImageList) ) or Images( COleVariant( (LONGLONG)hImageList) ), where hImageList is of HIMAGELIST type. The GetSafeHandle() method of the CImageList gets the HIMAGELIST handle (long, loads icon from HIMAGELIST type)
