Problem showing item in TreeView

My application uses a TreeView control and I'm having trouble showing an item. The program compiles perfectly fine, but when I run it, there isn't the item in the TreeView like I thought I programmed in. Any ideas? Here's the code where it adds an element to the TreeView (or at least that I thought would add an element):

Code:

---

void InitTree(void)
{
    TV_INSERTSTRUCT  tvs;
    TV_ITEM          tvi;

    tvs.hInsertAfter = TVI_LAST;
    tvi.mask = TVIF_TEXT;

    tvi.pszText = TEXT("test");
    tvs.hParent = TVI_ROOT;
    tvs.item = tvi;
    hTreeItem = TreeView_InsertItem(hTreeWndCtrl, &tvs);
    hTreeCurrent = hTreeItem;
}

---

Any ideas why I can't get my element to show up? What do I need to change/do?

Thanks!

Any ideas? Do you need to see more code? Please help. :(

I could pretend that I knew this off the top of my head, but the truth is that I spent thirty seconds reading the documentation.

TVIF_TEXT
The pszText and cchTextMax members are valid.

Code:

---

void InitTree(void)
{
    TVINSERTSTRUCT tvs = { 0 };

    tvs.hInsertAfter    = TVI_LAST;
    tvs.hParent        = TVI_ROOT;

    tvs.item.mask      = TVIF_TEXT;
    tvs.item.pszText    = TEXT("test");
    tvs.item.cchTextMax = lstrlen(tvs.item.pszText);

    hTreeItem    = TreeView_InsertItem(hTreeWndCtrl, &tvs);
    hTreeCurrent = hTreeItem;
}

Nope, didn't work. :( Any other ideas? I'm getting desparate now.

I have no idea. Have you checked that hTreeWndCtrl is valid? Called InitCommonControls? I'm sure someone here must have working treeview code. By the way, my last post may have been wrong, you may not need cchTextMax in this situation, although the documentation is unclear.

The MSDN sample shows:

Code:

---

    tvi.pszText = lpszItem;
    tvi.cchTextMax = sizeof(tvi.pszText)/sizeof(tvi.pszText[0]);

---

which is very wrong.
