ListView is not working!

When I put this code under my WM_CREATE area, the listview is displayed as a big empty white client-edged box. Why is this not making the columns?

Code:

---

        InitCommonControls();
        CreateCtrl(WC_LISTVIEW, NULL, WS_VSCROLL, WS_EX_CLIENTEDGE, ID_LIST, 0, 0, 0, 0);
        lvColumn.mask = LVCF_FMT | LVCF_TEXT | LVCF_WIDTH;
        lvColumn.fmt = LVCFMT_LEFT;
        lvColumn.cx = 100;
        lvColumn.pszText = "File Name";
        ListView_InsertColumn(GDI(ID_LIST), 0, &lvColumn);
        ListView_Update(GDI(ID_LIST), 0);
        lvColumn.mask = LVCF_FMT | LVCF_TEXT | LVCF_WIDTH;
        lvColumn.fmt = LVCFMT_LEFT;
        lvColumn.cx = 100;
        lvColumn.pszText = "File Size";
        ListView_InsertColumn(GDI(ID_LIST), 1, &lvColumn);
        ListView_Update(GDI(ID_LIST), 1);

CreateCtrl() is a working macro I made. So is GDI(). And I have the program set the size of it under WM_SIZE, which is also working great. I have already tried it with and without the update calls.

EDIT:
I changed ListView_SetColumn() to ListView_InsertColumn() but it's still not working. Please help.

EDIT 2:
Okay, nevermind, I see now. I was under the impression that the "SysHeader32" class was a part of the "SysListView32" class. Sorry for the bunk thread.

Okay now I have a question. How do I put items under other columns? By defualt it keeps placing them in the first one. (I'm using ListView_InsertItem().)

See ListView_SetItem

ListView_InsertItem() can do anything ListView_SetItem() can. Regardless though, I have already checked it out, how do I use it to place text under other coloumns??

Oh nevermind, I see what you mean; thanks for the help Joelito!
