I know I can use auto_ptr. I am not really using it in any project. It just feels good to know that you can implement this behavior sometime. Also, gives me a better understanding of the language and everything. Basically, just for educational purposes. That is all Smile | :)

Hey, that's cool - I've often done things to educate myself - experience IS the best way to learn. Just wanted to make sure you weren't implementing it because you didn't know about the already written alternatives!!

Something changed in MFC in VC7.0

Hi!

I recently ported several my projects from VC6 to VC7. I have noticed large memory leaks. After some debugging, I have found out that ExitInstance is not called any more. This is due to fact, that window is destroyed far more earlier (I think) than before. Application exits (quits ,immediately) in CFrameWnd::OnClose() during DestroyWindow() - last line in this method.
What is the reason?

I cannot find any document which describes this issue.
Confused | :confused:

is it possible?

Bitmap with scrolling capability

Hi all,

I have plced a Bitmap in my control in a static frame using the Load Image Function.Now the bitmap is seen as a compressed or expanded one depending on the bitmap selected to load in that frame. How can i make the bitmap to fit in my frame with the full size in such a manner that the visible part of the image is seen on the static frame and the remaining portions are seen when a scroll bar at bottom or side is moved?. In short how can i show a bitmap in a static frame with scrolling using load Image Function?.

With regards

You can't. You'll have to create your own window which supports loading images and scrolling.

Attributes and MFC

I was attempting to use ATL attributes in VS.NET in a MFC project (to hook to an event fired by a COM object) but in order to get it to compile had to include the [module(name="SomeName")] attribute. AFAIK this generates DllMain, DllRegisterServer, and whatnot code, but as an MFC app it already has a WinMain?! Well the app compiles and works, but I am wondering if this is correct or I am doing something wrong?

Dialog windows

I have a small dialog window that is a child of my parent dialog. It has the topmost window style set so I can be doing things in other windows and have my small child window of my app still visible on top of everything. When I click on the title bar to move it around the screen, upon releasing the mouse button, the parent dialog box pops up to right under the child dialog. This isn't the behaviour I'm desiring (I'd like to be able to move the child window around without seeing the parent, but I'm not sure how to get around it, or what to do. Any ideas?

Also, i'm taking a plain dialog resource for it (no controls), and in my OnPaint function for that dialog, calling GetClientRect() and drawing right to that rect. Is this wise?

ShowWindow(SW_SHOW)

-Drawing on that plain dlg that OnPaint (WM_DRAW) message should do no harm

Show popup menu not animated?

Can I create a popup menu (context menu) and make it apear at once, no animation.

Can I get the height of the created menu, I'd like to position it exatcly above a button?

Thanks for help!

1) I think you can't. There is only one way to solve this problem - switch "menu effects" options off in Windows Settings. Of course, you can paint menu manually, but is it worthy of that efforts?

2) Point is that Windows can place popup menus in different directions relative to point that you indicated to menu. It depends on how close this menu is to bounds of screen. If you will adjust menu position manually, it may result a bug in some particular case

I used BCMenu class, but any other ownerdraw menu works too. I need to figure out what makes it non sliding here on WIn9x, but at least it works.

void CBCDialogMenuDlg::OnButtonMenu() 
{
	BCMenu menu;						//create menu with bitmaps
	menu.LoadMenu(IDR_MYTYPE);
	BCMenu* pPopupMenu = (BCMenu*) menu.GetSubMenu(0);
	ASSERT(pPopupMenu != NULL);

    CRect rect;
	m_away.GetWindowRect(rect);

//	pPopupMenu->LoadToolbar(IDR_TOOLBAR_PROPERTY);	//load bitmaps for menu
	pPopupMenu->TrackPopupMenu(TPM_LEFTALIGN | TPM_RIGHTBUTTON, rect.left, rect.top, this);
}

good point. I'll make sure my window is big enough to hold the menu over the button.

When I said "paint menu manually" i indeed meant a ownerdraw menu. But remember that using of ownerdraw menus may lead to refusing from some Windows abilities as WinXP Themes and etc.

Somehow or other, we have found consensus Smile | :)

well.. I tried a bit with CButtonST. I can at least meassure the height of the menu there. Some code.... not finsihed yet, but seems to work:

void BCMenu::GetClientRect(LPRECT lpRect)
{
	lpRect->left=0;
	lpRect->top=0;
	lpRect->bottom=0;
	lpRect->right=0;

	MEASUREITEMSTRUCT MIS;
	BCMenuData *mdata;
	UINT nID;

	int num = GetMenuItemCount();
	for(int i=num-1;i>=0;--i)
	{
		nID=GetMenuItemID(i);
		mdata=FindMenuList(nID);

		MIS.itemData = (DWORD) mdata;
		MeasureItem(&MIS);

		lpRect->bottom += MIS.itemHeight;
		if(MIS.itemWidth > (unsigned) lpRect->right) lpRect->right = MIS.itemWidth;
	}

	lpRect->bottom+=5;	//add some pixels for borders
}

PS: I have choosen ownerdraw menu because I like the possibility bitmaps in menus Smile | :)

'TPM_NOANIMATION' is not declared (MSDN mentions it though).
I run WinME here and can't find this text string in any *.h file (I scanned my harddisk for it)
