I need help with sending strings to a ListBox

[Nobody/Anonymous]

Hi, im sending a string to a list box like this:
SendMessage(hwndLB01, LB_ADDSTRING, 0, (LPARAM) (LPCTSTR) string01); Its kindda of a log window, in the start of all my important functions, i will send a messages to the ListBox saying "Function X() was called" and at the end of the functions ill send a message "function x() returned 0", or returnet 1, etc...

I have that already working, no problems at all. But what i want now is to place date/time the string was send to the ListBox, right before the String itself. Lines at the ListBox would now  look like "XX/XX HH:MM:SS - Function X() was called.". 

It would have to be something like that:

printDebug() {
datetime() {
//Here we get Date and Tiem and set at datetimestr
}
SendMessage(hwndLB01, LB_ADDSTRING, 0, (LPARAM) (LPCTSTR) , datetimestr, string01);
}

But, as i could see in all my lameness theres no way to send a LB_ADDSTRING message with two strings. And if i send two Messages, one with each string, they go in the ListBox in separated lines.

Can anyone give me some help on that please?

Thank you :)

I'm programming with DEV C++.
I creatred one form with 3 listboxes, but only on the first I can add items (rwos), the others two seems to be active but not managed by the program.

To create the listboxes I worte, under the WM_CREATE:

hWndListBox1 = CreateWindowEx(0,"LISTBOX", NULL, WS_VISIBLE | WS_CHILD | WS_VSCROLL | WS_BORDER,
30, 30, 200, 800, hwnd, (HMENU)IDC_LISTBOX_TEXT1, (HINSTANCE)GetWindowLong(hwnd, GWL_HINSTANCE), NULL);
if (!hwnd)
MessageBox(NULL, "ListBox 1 Failed.", "Error", MB_OK | MB_ICONERROR);
SendDlgItemMessage(hwnd, IDC_LISTBOX_TEXT1, WM_SETFONT, (WPARAM)hFont_list, TRUE);

hWndListBox2 = CreateWindowEx(0,"LISTBOX", NULL, WS_VISIBLE | WS_CHILD | WS_VSCROLL | WS_BORDER,
330, 400, 200, 418, hwnd, (HMENU)IDC_LISTBOX_TEXT2, (HINSTANCE)GetWindowLong(hwnd, GWL_HINSTANCE), NULL);
if (!hwnd)
MessageBox(NULL, "ListBox 2 Failed.", "Error", MB_OK | MB_ICONERROR);
SendDlgItemMessage(hwnd, IDC_LISTBOX_TEXT2, WM_SETFONT, (WPARAM)hFont_list, TRUE);

hWndListBox3 = CreateWindowEx(0,"LISTBOX", NULL, WS_VISIBLE | WS_CHILD | WS_VSCROLL | WS_BORDER,
600, 400, 200, 418, hwnd, (HMENU)IDC_LISTBOX_TEXT3, (HINSTANCE)GetWindowLong(hwnd, GWL_HINSTANCE), NULL);
if (!hwnd)
MessageBox(NULL, "ListBox 3 Failed.", "Error", MB_OK | MB_ICONERROR);
SendDlgItemMessage(hwnd, IDC_LISTBOX_TEXT3, WM_SETFONT, (WPARAM)hFont_list, TRUE);

The first listbox runs with the call:
SendMessage(GetDlgItem(hwnd, IDC_LISTBOX_TEXT1), LB_ADDSTRING, 0, (LPARAM)Testo_Val1);

To add items on the listbox 2 I use:
SendMessage(GetDlgItem(hWndListBox2, IDC_LISTBOX_TEXT2), LB_ADDSTRING, 0, (LPARAM)Testo_Val2);

but on the listbox 3 I tried with:
SendMessage(hWndListBox2, LB_ADDSTRING, 0, (LPARAM)Testo_Val2);

I also tied with:
SendMessage(GetDlgItem(hwnd, IDC_LISTBOX_TEXT3), LB_ADDSTRING, 0, (LPARAM)Testo_Val2);

but without any result.

I can't understand why the listboxes 2 and 3 aren't managed.

NOTE:

char Testo_Val1[25];
char Testo_Val2[25];
char Testo_Val3[25];

Thanks in advance for any help!!!
