Tree-View Control

[dit6a9]

I'm developing a simple Window application which tries to use TreeView Control (http://msdn.microsoft.com/library/default.asp?url=/library/en-us/shellcc/platform/commctls/treeview/treeview.asp).

The main routines are (I don't write the full code because it would make the post a little bit unreadable):

hwndDialog = CreateDialog(GetModuleHandle(NULL), "DIALOG_0", hwnd, dialogProc);
CreateATreeView(hwndDialog, "");
...
...
HWND CreateATreeView(HWND hwndParent, LPSTR lpszFileName)
{
RECT rcClient;
HWND hwndTreeView;

InitCommonControls();
GetClientRect(hwndParent, &rcClient);

hwndTreeView = CreateWindowEx(
0,
WC_TREEVIEW,
"Tree View",
WS_VISIBLE | WS_CHILD | WS_BORDER | TVS_HASLINES,
0,
0,
rcClient.right,
rcClient.bottom,
hwndParent,
(HMENU)ID_TREEVIEW,
hInstance,
NULL);

return hwndTreeView;
}

BOOL InitTreeViewImageLists(HWND hwndTreeView)
{
HIMAGELIST himl;
HICON hIcon;

if ((himl = ImageList_Create(32, 32, FALSE, 2, 0)) == NULL)
return FALSE;

hIcon = LoadIcon(NULL, "folder.ico");
if (hIcon==NULL) return FALSE;
ImageList_AddIcon(himl, hIcon);

hIcon = LoadIcon(NULL, "folder_closed.ico");
if (hIcon==NULL) return FALSE;
ImageList_AddIcon(himl, hIcon);

TreeView_SetImageList(hwndTreeView, himl, TVSIL_NORMAL);

return TRUE;
}


I'm using Dev-C++ 5.0 beta 9 (4.9.9.0) with Mingw/GCC 3.3.1.

After including commctrl.h I tried to build de proyect and I got the following error:

Compilador: Default compiler

Somehow I concluded (I don't remember why, because I spent a lot of time trying and trying different things and reading tutorials and articles) that I had to add the comctl32.lib to the proyect. Was I right? I don't know. The first problem was that I had no idea about where I could find comctl32.lib. I searched my PC, just for trying, and since I got installed Microsoft Platform SDK (http://www.microsoft.com/msdownload/platformsdk/sdkupdate/), I found out that comctl32.lib was in the "\Microsoft SDK\Lib" folder.

After including comctl32.lib to my proyect I got the following errors:

Compilador: Default compiler

Then I said to myself that maybe I had to use the CommCtrl.h within the Platform SDK so I changed:

#include <commctrl.h>

and I wrote:

#include "..\..\Archivos de programa\Microsoft SDK\include\CommCtrl.h"

...and I got more and more errors:

What am I missing? Can't Tree-View control be used?

As you can see by the length of my post, I'm going a little bit crazy. Any help would be wellcomed. Thanks in advance.

If I remember well, gcc recomends not to link the *.lib files for DLLs but link to the DLLs directly. That is include the comctl32.dll into the project instead of comctl32.lib and see what happens...

The main routines are (I don't write the full code because it would make the post a little bit unreadable):
It is unreadable already. I think you would be better off posting your project.

You can also use code tags. This makes it alot more readable.
