Discussion on dialog resizing in source code forum

[Jules Marchildon]

Hi Mike,

Are you still having trouble with sizing a control inside a fixedd dialog?
Email a sample snippet and I'll fix it for you. jmXpressATlookDOTca

Very Nice Carlo,

How would you modify it to allow you to resize on of the ListViews
inside the window WITHOUT resizing the window?

------------------
Kind Regards
Mike

[Carlo Pagani]

Thanks for making the changes Chris.

Hi Jules,

Thanks for nice comments.

Not meant to compete with Lance, just intended to provide a usefull tool to newbies
starting off with PB to make life a little easier. For me resizing was a big hurdle in moving
to windows so I thought I'd share these fairly simple routines in exchange for all the good
stuff I've got out of this forum in the past.

Regards - Carlo

Very Nice!

I use Lance's custom Resize32 DLL, it's the cat's meow of resize controls!

Regards,
Jules

Carlo,

I added the fixes you noted and then I added code to free all
the properties, when the dialog is destroyed. There shouldn't be
a memory leak anymore.

I reposted the fixed program.

Thanks Chris,

I thought everyone had moved to V7 However your version does not work for me
on W2K and PB6.11 or 7. The whole dialog goes grey as soon as I resize
------------------

OK - Chris, found problem - pse edit your code to use MAKLNG for Get/SetProp
Also note that a small memory leak may be created without using RemoveProp when exiting the dialog.

SUB Rz_SetUser(BYVAL hDlg&, BYVAL ControlID&, BYVAL N&, BYVAL UData&)
    IF N&<1 OR N&>4 THEN EXIT SUB
    IF ControlID&=0 THEN
        SetProp hDlg&, BYVAL MAKLNG(App_UserDataAtom&(N&), 0), UData&
    ELSE
        SetProp GetDlgItem(hDlg&, ControlID&), BYVAL MAKLNG(App_UserDataAtom&(N&), 0), UData&
    END IF
END SUB

FUNCTION Rz_GetUser(BYVAL hDlg&, BYVAL ControlID&, BYVAL N&) AS LONG
    IF N&<1 OR N&>4 THEN
        FUNCTION=0
        EXIT FUNCTION
    END IF
    IF ControlID&=0 THEN
        FUNCTION=GetProp(hDlg&,BYVAL MAKLNG(App_UserDataAtom&(N&), 0))
    ELSE
        FUNCTION=GetProp(GetDlgItem(hDlg&, ControlID&),BYVAL MAKLNG(App_UserDataAtom&(N&), 0))
    END IF
END FUNCTION

Very impressive Carlo !!!

It seemed ashame though that your code could only be used with
PB 7.0, so I did a conversion of your program by adding 3 more
routines to the inc file, so it can be used with PB 6.0/6.1 .
(see: Source Code Forum)

I converted the CONTROL SET USER, CONTROL GET USER, DIALOG GET USER
and DIALOG SET USER commands (only in PB 7.0) to custom functions
which use properties. The properties are accessed using Atoms, so
they are quite fast.

Now everybody can benefit from your efforts !
