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.
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
