Hi! How to use tabcontrol?
I just build a resource file with my resource editor and put a tabcontrol on the dialog, but how to use it?

Thanks!

Well, first of all - read carefully "Tab control reference" and related in win32.hlp
Then you have to create several tab items (TCM_INSERTITEM) and also, corresponding controls as a children of the tab control. Only one of them have to be visible at a time.
Store the handles of the children in corresponding tab item using lParam member of TCITEM structure.
Then process TCN_SELCHANGE and TCN_SELCHANGING notification messages (WM_NOTIFY) and on every new selected tab, hide the previous visible child and show the new one.
Of course you have to handle WM_SIZE of the parent to ensure the size of the tab control itself and the size of the children will fit exactly in the client area. You should use TCM_ADJUSTRECT to get the tab control client area, clear for children.

You can see pretty clear example in Fresh sources, file "editorhost.asm" - especially read WM_NOTIFY message handle and EHM_DOCKWINDOW (from the label .addtotabs) and _EHM_SETACTIVETAB (note that Windows doesn't send notification messages if the tab is selected through TCM_SETCURSEL message, so you have to send them yourself).

Regards.

fasmw also uses a tab control, you may want to browse thru the source

Just replace the first line of source with:
Code:
include '%fasminc%\win32ax.inc'

The prototype (not checked) would look like this:
Code:
        FIRST_CHILD_WINDOW_ID = 1
       ;...
        uglobal
          ChildWindowHandles:
            .Child1 dd ?
            .Child2 dd ?
            .Child3 dd ?
            .Child4 dd ?
           ;...
            .Childn dd ?
            NB_OF_WNDS = (($-ChildWindowHandles)/4)
        endg
       ;...
        ; creating all windows
        push    esi edi ebx
        mov     edi, ChildWindowHandles         ; all window handles will be stored there
        mov     esi, NB_OF_WNDS                 ; counter
        mov     ebx, FIRST_CHILD_WINDOW_ID      ; windows' IDs
     @@:
        invoke  CreateDialogParam, [hInstance], ebx, [hMainWindow], ChildWndProc1, 0
        stosd
        inc     ebx
        dec     esi
        jnz     @B
        pop     ebx edi esi
       ;...
        invoke  ShowWindow, [ChildWindowHandles.Child1], SW_SHOW
       ;...
        ; in window procedure
        cmp     [.uMsg], WM_NOTIFY
        jz      .notify
       ;...
        ; check if notify message is about tab control
  .notify:
        mov     eax,[.lParam]
        cmp     [eax+NMHDR.code], TCN_SELCHANGE
        jz      .selchange
        return
      .selchange:
        ; hide last window
        mov     eax, [LastShowedTab]
        invoke  ShowWindow, [ChildWindowHandles+eax*4], SW_HIDE
        ; show newly selected window
        invoke  SendMessage, [hTabControl], TCM_GETCURSEL, 0, 0
        mov     [LastShowedTab], eax
        invoke  ShowWindow, [ChildWindowHandles+eax*4], SW_SHOW
        return

This thread was very helpful for me, and finally i could compile the tabctrl example of veach1, which helped me a lot! But i have a question regarding the child-windows of the tabs. Veach1 creates elements by invoking CreateWindowEx, but since you often have more content in those child-windows than a button or an edit-box, i wanted to create the child-windows by invoking DialogBoxParam... which crashes successfully.
So could anyone please give me a hint of how one can create "complex" child-windows using resources? Thank you!

P.S. I ALREADY had a look into the Fresh-editorhost.asm file.

EUPHORIA!! I have now found out how to include "resource"-dialogs into the different tabs: For that i invoke the function CreateDialogParam.
The program "Sorting algorithms in Assembler", found on this site: http://www.codingcrew.de/marty/win32asm.php helped me out! Thank you dear program Wink
