On files, I use GetFileTime() function and it is
working property, but on folder, it returns null.

checkbox check problem

c. s.7-Jul-05 7:11

7-Jul-05 7:11

I am a beginner in the windows programming world, and am having a bit of trouble figuring out how to determine the state of my checkbox when it's ownerdraw.
If I use BM_GETCHECK it always returns 0, even if I send BM_SETCHECK a line above passing BST_CHECKED. I also tried ORing BS_CHECKBOX and/or BS_AUTOCHECKBOX with BS_OWNERDRAW but BM_GETCHECK still returned 0.
I then attempted to use BM_SETIMAGE as general storage (a pointer) but BM_GETIMAGE always returns 0 as well.
Is it due to the fact my checkboxes are ownerdraw, or is there some other problem I'm unaware of?

thanks

hTempWnd = CreateWindowEx (
										0,										// no extended style
										"Button",	
										"Compression",							// toggles chunk compression
										WS_VISIBLE | WS_CHILD | BS_OWNERDRAW,	// make a visible child window, that we draw ourself (see void DrawCheckbox)
										clientRect.right - MM_DBUTTON_WIDTH - MMPADDING_RIGHT,		// create it near the top right corner
										clientRect.top + MMPADDING_TOP + MM_GROUPPADDING_BOTTOM,
										MM_DBUTTON_WIDTH, MM_DBUTTON_HEIGHT,	// use our standard checkbox button height and width
										hWnd,									// our parent window is this popup menu
										(HMENU) MMENU_BUTTON_COMPRESSION,
										GetModuleHandle ( NULL ),
										NULL									// pass no extra parms on creation
									) ;

LPDRAWITEMSTRUCT lpdis from lParam in WM_DRAWITEM

long lResult = 0;

		lResult = SendMessage ( lpdis->hwndItem, BM_GETCHECK, (WPARAM) 0, (LPARAM) 0 ) ;
		if ( lResult == BST_CHECKED ) ...

When I was trying BM_GETIMAGE I used the same procedure as the second code snippet

edit: It seems that BM_GETCHECK and BM_SETCHECK just don't work with ownerdraw, so that solves that issue, but I'm still unsure why BM_SETIMAGE doesn't work.

David Crow7-Jul-05 8:02

7-Jul-05 8:02

What happens if you create a checkbox like:

CreateWindowEx(..., WS_VISIBLE | WS_CHILD | BS_AUTOCHECKBOX, ...);

In other words, does the owner-draw style have any affect? I wouldn't think so but I'm just trying to pare the problem down.

I have tried using BS_AUTOCHECKBOX with BS_OWNERDRAW (I do draw them myself so I need that) but it doesn't seem to have an effect, and BM_GETCHECK still always returns 0.

Right, but does the problem persist for non owner-drawn checkboxes?

According to this[^], an owner-drawn button "has no predefined appearance or usage. Its purpose is to provide a button whose appearance and behavior are defined by the application alone."

Furthermore, your call to Create isn't even specifying one of the possible check box styles (BS_CHECKBOX, BS_AUTOCHECKBOX, BS_3STATE, BS_AUTO3STATE), so it's no wonder the control doesn't react to BM_SETCHECK messages. Try adding BS_CHECKBOX, and if that doesn't work (which may be due because of the owner draw style), I suggest subclassing the control so that you can handle the BM_GETCHECK and BM_SETCHECK messages yourself.

Hope that helps,

I was hoping to avoid using my own storage, but it seems not too feasible.
I will subclass it and see how it turns out, thanks all.

Well, subclassing it would have an additional benefit, since it would allow you to handle the drawing in the control, rather than doing so in the parent. That's in my opinion a better alternative because it's easier to reuse the control with different parents.

Good luck Smile | :)

Greetings:

I have a simple ListCtrl box in Report mode. I want the parent window (a dialog) to be notified when any vertical scroll operations are requested.

I can't see anyway to do this. Is it a WM_NOTIFY? If so, which code ID is used?

Thank you,
Mark

In Windows XP, you have LVN_BEGINSCROLL / LVN_ENDSCROLL:
Check it in MSDN[^]

Is that what you are looking for?

What's your need exactly? I mean, you said you need a parent window to receive notifications about scrolling in a listview, but what do you need this for? Perhaps there's another way to do what you actually need.

For example, would subclassing the control with a class derived from CListCtrl help? Doing that would allow you to handle any windows message...

Hi Jose:

My problem is that I must provide a list control in report mode that displays records with about five sub-items per row. This view must potentially display a LARGE number of records, sometimes over 200,000. Normally, if the record count was lower, I would just insert all the rows I need and fill out all of the records then the user is free to scroll away. But when the number of records is large, it takes WAY too long to initialize all of those records.

I found that if I simply create the number of rows that I need without filling out any of the record data in the columns, then the amount of time it takes is tolerable (like 30 seconds with a friendly progress bar to amuse the user in the mean time).

My next move, if I can figure out how to do this, is to simply fill out only the records that are currently visible in the view window. Each time the user scrolls by whatever means, I would fill out any rows that become exposed but have not been filled out. This all hinges on me being notified when the user has caused the list control to scroll and to then find out which rows are now visible.

That's my plan. Feel free to rip it apart.

Thanks,
Mark

I figured it was something like that, hence the question Smile | :)

This article seems to be what you need:
Using virtual lists[^]

I haven't tried it, but it's the approach I'd suggest in your case (letting the list ask you for the info as it needs it).
