A Question about DDT, SetParent and Messages

[LRantanen]

Hi all,

this time I'd like to ask following question from you more seasoned PB/DLL programmers.

I have a DDT created dialog where I add Image controls. However, I like to have these image controls inside another control (which I think VB programmers know as Panel). I do all this in following code

    ' Add container window for bitmaps
    CONTROL ADD LABEL, hDlg, %CONTAINER, "", 5, 15, 150, 20 , %WS_THICKFRAME OR %SS_NOTIFY
    CONTROL HANDLE hDlg, %CONTAINER TO hWndBrowse
	    
    ' Add image controls for the bitmaps
    FOR i = %FIRST_BMP TO %LAST_BMP
        sBmp = "#"+TRIM$(STR$(i))
        CONTROL ADD IMAGE,  hDlg, i, sBmp, _
                            0, 0,16,16, _
                            %WS_TABSTOP OR %SS_NOTIFY
        CONTROL HANDLE hDlg, i TO hWndTemp
        SetParent hWndTemp, hWndBrowse
        MoveWindow hWndTemp, 5 + (i - %FIRST_BMP) * 18, 5, 16, 16, %TRUE
    NEXT

That works OK.

Now the problem to me is how to intercept the messages these Image controls send?

If I comment out SetParent and MoveWindow statements following code does what I want

	SELECT CASE CBMSG
       CASE %WM_COMMAND
            SELECT CASE CBCTL
                CASE %FIRST_BMP TO %LAST_BMP
                     IF CBCTLMSG = %STN_CLICKED THEN
                        IF iSelected > 0 THEN
                            CONTROL SET IMAGE CBHNDL, iSelected, "#"+TRIM$(STR$(iSelected))
                        END IF
                        iSelected = CBCTL
                        CONTROL SET IMAGE CBHNDL, CBCTL, _
                                          "#"+TRIM$(STR$(iSelected + nOffsetToHilightedBmps))
                     END IF
 
                ' Other cases
 
            END SELECT
    END SELECT

Can anybody give me some advice how to approach this in case I have changed the parent window of Image controls? I'd like to continue using DDT when creating the dialog.

TIA

Once again, too complicated approach. The way to achieve what I was after is to use LINE control supplied, no need for SetParent and stuff. So - ignore this question.

Sorry about wasting bandwidth,
