Recently Started working on MSComctlLib TreeView and ImageList
want to figure out how to use images in my TreeView, also how to set background to my TreeView object;
using C# windows application, writing addon for sap b1 which has ActiveX support.
so what I did
loaded MSComctlLib.TreeCtrl.2 object
loaded MSComctlLib.ImageListCtrl.2 object
code snippet for ImageList
var type = Type.GetTypeFromProgID("MSComctlLib.ImageListCtrl.2"); var inst = Activator.CreateInstance(type) as MSComctlLib.ImageList; var image = Image.FromFile("Images/folder.bmp"); //tried with .png as well
then created IPictureDisp object using Microsoft.VisualBasic.Compatibility.VB6 namespace
var imgObj = Support.ImageToIPictureDisp(image); inst.ListImages.Add(ref ind, ref key, imgObj1); //here getting error
but when I'm trying to add imgObj to ListImages getting
Catastrophic failure (Exception from HRESULT: 0x8000FFFF (E_UNEXPECTED)) at MSComctlLib.IImages.Add(Object& Index, Object& Key, Object& Picture)
I want to create ListImage instance to use it in my TreeView ImageList. set background of TreeView but can't figure out how to make all this work.
looked in http://www.virtualsplat.com/tips/visual-basic-treeview-control.asp
Also tried using Resource file with images. This way getting invalid picture.
object ind = 1; object key = "1"; inst.ListImages.Add(ref ind, ref key, Properties.Resource.folder_bmp);
P.S. Is there any other alternative to ImageToIPictureDisp? because this library is already obsolete and working only on 32bit processes
