DialogBox fuction not executing its procedure [SOLVED]

[coco243]

Can you please tell me where these adjustments were? So I can take a look at me? Teach me how to fix that problems, where to look. Because it can be from the dialog resource to not load properly the DialogBox and not to go to the Dialog procedure from that reason. Where can be the problem on me? ( I am using VS 2010 and I did't had problems with it until now). Thank you,

I do not think they will help since they are just there to simulate what is provided by VS2010. However you can add them to the beginning of the .rc file to see what happens:

#include #define APSTUDIO_INVOKED
#define LBX_NOINTEGRAL_HEIGHT LBS_NOINTEGRALHEIGHT

Hmmm.... When I am creating a new empty project, when I choose to add a new .rc file, in this .rc file it's added automatically some code in that file, I was glad to see that, BUT!!! :mad:, it's appears that somewhere here was some problems or I wasn't pay attention on something, now I have copied exactly the content of the .rc file provided with the book, and now when I run the project, it's appearing an empty dialog box, it is emty, without the ListWiew, but it's a great start. I will put tomorrow the content of the file from the book because I am very tired now, and for shure we will see the critical diferences and for shure I will learn from that. Whoa, I am so glad, we will find and figure out what the clue is, thank you Richard for your patience. Thank you,

Comed back with the differences: Automated .rc file produced by VC with code introduced by me in bad position:

I just added your corrected .rc file to the project I have and it builds correctly. And when I run it, it shows the (empty) ListBox as expected.

I have now modified the Dlg_OnInitDialog function as below and the ListBox gets populated with file and directory names.

BOOL Dlg_OnInitDialog(HWND hwnd, HWND hwndFocus, LPARAM lParam)
{
RECT rc;
char szPath[MAX_PATH]; // reserve space for the path

// Associate an icon with the dialog box.
//chSETDLGICONS(hwnd, IDI\_DIRWALK, IDI\_DIRWALK);
SendMessage(hwnd, WM\_SETICON, TRUE, (LPARAM)LoadIcon(GetWindowInstance(hwnd), MAKEINTRESOURCE(IDI\_DIRWALK)));
SendMessage(hwnd, WM\_SETICON, FALSE, (LPARAM)LoadIcon(GetWindowInstance(hwnd), MAKEINTRESOURCE(IDI\_DIRWALK)));

GetClientRect(hwnd, &rc);
SetWindowPos(GetDlgItem(hwnd, IDC\_TREE), NULL, 0, 0, rc.right, rc.bottom, SWP\_NOZORDER);

**strcpy(szPath, "< path to the directory to search >");
DlgDirList(hwnd, szPath, IDC\_TREE, 0, DDL\_DIRECTORY | DDL\_READWRITE); // populate the ListBox**
return(TRUE);

}

Note that the DlgDirList function needs to write into szPath so it must be created in the way I have shown.

Yes, My Listbox was empty and I was't observed that it was a Listbox. Thank you, see you soon with new topics.
