you need to use
CImageList* SetImageList( CImageList * pImageList, int nImageListType );
before you do insertitem and in that pass the index in the imagelist you need to display .

I test this code and it work (you need to a resource(bitmap))

<code>
	TVINSERTSTRUCT	TreeCtrlItem;
	CBitmap Bmp;
	CImageList *m_ImageList;
	HTREEITEM hTreeItem1;
	m_ImageList = new CImageList();
	m_ImageList->Create(50,50, ILC_COLORDDB,0,0);
		Bmp.LoadBitmap(IDB_BITMAP1);//resource bitmap with 5 image on it

		m_ImageList->Add(&Bmp,RGB(155,155,155));

	TreeCtrlItem.hParent = TVI_ROOT;
	TreeCtrlItem.hInsertAfter = TVI_LAST;
	TreeCtrlItem.item.mask = TVIF_TEXT |TVIF_IMAGE|TVIF_SELECTEDIMAGE;

	TreeCtrlItem.item.pszText = CA2T("(A)");;//if you use from VS2005 instead CA2T use LPTSTR();
	TreeCtrlItem.item.lParam = 0;
	TreeCtrlItem.item.iImage=0;
	TreeCtrlItem.item.iSelectedImage=0;
	hTreeItem1 = m_Tree1.InsertItem(&TreeCtrlItem);
		m_Tree1.SetImageList(m_ImageList, LVSIL_NORMAL);

	TreeCtrlItem.hParent = hTreeItem1;
	TreeCtrlItem.item.pszText = CA2T(" (B)");
	TreeCtrlItem.item.lParam = 1;
	TreeCtrlItem.item.iImage=1;
	TreeCtrlItem.item.iSelectedImage=1;
	m_Tree1.InsertItem(&TreeCtrlItem);
	m_Tree1.SetImageList(m_ImageList, LVSIL_NORMAL);

_endthreadex()

I have an application that uses threads. The purpose of one thread is to Listen for any communication request from other machines. This has an infinite while loop. There have to be 2 stopping conditions for the same. One is when it receives a Stop boolean variable, it stops the whole application.

The other condition I want to add is that if it sees a global boolean variable is set (which needs to be set by some other thread of the same application) it should end that particular listen thread only (not the whole application). If I use _endthreadex() how will the other thread form which the boolean variable was set know that the listen thread has actually ended?

I was using TerminateThread() to end the Listen thread because it accepts the handle of the thread as an argument so that I was able to end the thread from some other thread but I see it is not cleaning up after Terminating the thread.

program listen thread something line this

g_bEndListenThread=FALSE;
while(1)
{
if(g_bEndApplication==TRUE)
   // End listen thread
     return 0; or _endthreadex();

if(g_bEndListenThread==TRUE)
   // End listen thread
     return 0; or _endthreadex();

// Do normal functioning

}

If a thread or process terminates, the OS-internal thread/process object is set to signaled state - the state you can use to wait for with e.g. WaitForSingleObject(). So if hThread is your thread handle, the following would wait until the thread has actually terminated:

WaitForSingleObject( hThread, INFINITE )

The point is that you might also use the waiting functions to test if an object (in this case the thread) is in signaled state (in this case has terminated) by just using 0 as the timeout value:

if( WaitForSingleObject( hThread, 0 ) == WAIT_TIMEOUT ) {
// not terminated yet
}

In call of TerminateProcess api, system will close the thread, without releasing any of it memory and related stuff. there might be case the system hang indefinatly at the call of WaitForSingleObject api!

to disable the pushbutton if no item is selected in the list you can do this
m_button.EnableWindow(false);
if you select an item enable the window
m_button.EnableWindow();

For your question on is there any other way.......editor
See Here[^]

Somethings seem HARD to do, until we know how to do them.

m_button.EnableWindow(false);
if you select an item enable the window
m_button.EnableWindow();

You need to disable the button when you are showing the dialog.
Can you tell how are you creating your dialog? (using which API if not in the resource editor)

yeah sure. I will try my level best to solve your problem
First search in your code that are you using the CreateDialog() to create the dialog or CreateDialogIndirect()

Somethings seem HARD to do, until we know how to do them.
