TreeView change item

[nym313]

Hi
Using the following code I defined that when Im loading the Announcements into the program it marks the some of them with various icons in the TreeView. This was fairly easy, because when I pasted a new element into the tree (hTemp = GetTreeCtrl().InsertItem(pDoc->m_pAnnouncements[ann].m_cAnnouncementName, SecondParentItem, TVI_LAST), I got the tree element back into the hTemp variable, and I could easily change the picture.
My question would be that how could I go through the Announcements and modify their icons, but without clicking anywhere in the tree.
Thanks for any help in forward!
Screenshot and code follows:

for(int ann = 0; ann < pDoc->m_iAnnouncements; ann++)
	{
		hTemp = GetTreeCtrl().InsertItem(pDoc->m_pAnnouncements[ann].m_cAnnouncementName, hSecondParentItem, TVI_LAST);
		GetTreeCtrl().SetItemData(hTemp, TREEITEM_TE_ANN_ANN);
		
		CString sSelItemText;
		sSelItemText = GetTreeCtrl().GetItemText(hTemp);
		DWORD type = GetTreeCtrl().GetItemData(hTemp);

		int iAnnId;
		for(j = 0; j < pDoc->m_iAnnouncements; j++)
		{
			if(pDoc->m_pAnnouncements[j].m_cAnnouncementName == sSelItemText)
			{
				iAnnId = pDoc->m_pAnnouncements[j].m_iAnnouncement;
				break;
			}
		}

		int iCount = -1;
		for(i= 0; i < pDoc->m_iNodes; i++)
		{
			int iNodeindex = -1;
			for(int t=0;t<pDoc->m_iNodeTypes;t++)
			{
				if((UINT)pDoc->m_pNodeTypeData[t].m_iNodeType == pDoc->m_pNodes[i].m_iNodeType)
				{

			{
				//ExitProcess(-12);

You need to use the GetItem() member function to iterate through the item of the Tree control and then use the SetItem() member function to change the image index for the tree item. The image index is a integer inde in to the tree control's image list.
