Hi all,
In my win32 application,I want to createa window with 3 column & N rows.By using Listview control (Report style)How can i create this table.Please give me some sample code

Ill assume you want to put this in your main window.
Here is an example: (This is your WndProc for your window)

#define LISTVIEW 101        // Listview resource handle

LRESULT CALLBACK WndProc(HWND hwnd, UINT msg, WPARAM wParam, LPARAM lParam) {
    switch (msg) {
        case WM_CREATE: {
            hwnd hListView;        // Listview window handle
            LVCOLUMN LvCol;        // List column data structure
            char temp[256];        // Temporary data to store the title in.

            // Create the ListView control
            hListView = CreateWindowEx(WS_EX_CLIENTEDGE,
                                       WS_VISIBLE | WS_CHILD | LVS_REPORT,
                                       0, 0, 100, 100,         // These don't really matter
                                       hwnd,
                                       (HMENU)LISTVIEW,  // The resource value for the handle
                                       GetModuleHandle(NULL),
                                       NULL);
            if (hListView == NULL)        // Couldn't create listview for some reason.
                MessageBoxA(hwnd, "Could not create listview.", "Error", MB_OK | MB_ICONERROR);

            ZeroMemory(&LvCol, sizeof(LVCOLUMN));    // Clear the memory
            LvCol.mask = LCVF_TEXT;            // Only using text for the titles
            LvCol.cx = 0x66;                // Width of the columns

            // Get the column name from a string table
            LoadString(GetModuleHandle(NULL), IDS_COLUMN1, temp, 256);
            LvCol.pszText = temp;

            // Insert the column
            SendMessage(hListView, LVM_INSERTCOLUMN, 0, (LPARAM)&LvCol);

            // Add 2 more columns
            for (int i = 1; i < 3; i++) {
                LoadString(GetModuleHandle(NULL), IDS_COLUMN1 + i, temp, 256);
                LvCol.pszText = temp;
                SendMessage(hListView, LVM_INSERTCOLUMN, i, (LPARAM)&LvCol);
            }
        } break;

        case WM_SIZE: {            // When the window is resized
            HWND hListView;        // Handle to the listview
            RECT rcClient;            // Size of the client window
            int nListHeight;        // Stores the height of the listview.

            GetClientRect(hwnd, &rcClient);        // Get the height of the window
            nListHeight = rcClient.bottom - rcClient.top;    // Fit the ListHeight inbetween.

            hListView = GetDlgItem(hwnd, LISTVIEW);        // Get the handle for the listview
            // Set the listview size to fill the screen completely.
            SetWindowPos(hListView, NULL, 0, 0, rcClient.right, nListHeight, SWP_NOZORDER);
        } break;

        // (... Other things go here ...)

        default:        // Let windows process unhandled messages
            return DefWindowProc(hwnd, msg,wParam, lParam);
    }

    // Let windows know we handled the message ourselves.
    return 0;
}

Your CreateWindowEx call is missing the class name and window name??

Anyway, the code below runs.
- You have to call InitCommonControlsEx before you try and create a List View
- And you have to get your flags write for LVM_INSERTCOLUMN
- etc

I am also using the List View macros rather than the messages, e.g. ListView_InsertColumn rather than SendMessage with LVM_INSERTCOLUMN (as shown here:
