Re: Problems iterating through a std::map

My wild stab in the dark would be that if they both point to the same address, then _Nil is what's changing and therefore it seems your copying only the first element between dll's. _Nil obviously changes, have you actually asked the map how many elements it has ?

How can _Nil be changing since it is defined static?

static _Nodeptr _Nil;

and is initialized with 0

template<class _K, class _Ty, class _Kfn, class _Pr, class _A>
        _Tree<_K, _Ty, _Kfn, _Pr, _A>::_Nodeptr
                _Tree<_K, _Ty, _Kfn, _Pr, _A>::_Nil = 0;

I have checked, it has the same number of elements and I can find them all if I put the map in the watch and expand the _Left, _Right and _Parent correspondents... Cry | :((

You are right after all Chrstian. _Nil changes, but why?

Here is what happens:
class A is in A.dll and class B : public A is in B.dll
Class A has a map as its member. (I'll call it MyMap)

1. I am now in a method of class B. Here MyMap._Tr._Nil is NULL (0x00000000)

2. This method will call a parent method from class A. Just stepping into that method (withought touching the map object) I will find that MyMap._Tr._Nil is no longer NULL. I can work with the MyMap fine, inserting elements and iterating through it.

3. I return to the method described at 1. Now MyMap._Tr._Nil is NULL again Confused | :confused:

. Now playing with the map screws up my application.

Any idea?

Alexandru Savescu

Sorry for replying for the third time to the same method. I found the solution and I thought you might want to know:

Get an updated version of xtree from Dinkumware. Also, VC.NET does not need this patch.

hello..

as a background process, i should print pdf files...

does anybody know any good library (commercial should be no problem) for this?
i tried messing around with the activeX - component.. but it should be a plain c++ file, without any dialogs, the best would be even without mfc...

thanks in advance (i have to say that i am ont able to response until monday.. because my weekend starts in 5 minutes)

You can buy a PDF print driver direct from Adobe. Then you can create a printer DC as normal and print as you require. We use it embedded in our software to generate PDF files.

i need it the other way round... a background process should print pdf files out..

first a normal printout from an application (with barcodes..)
then some pages from a pdf file..
(and this should be a background process.. so no gui..)

Program icon when minimized app

ViolaCase11-Jul-02 23:20

11-Jul-02 23:20

Situation: I built a dialog based mfc-win32-app.
Because the app works with skins, the main dialog has no borders nor caption.
Problem: The program DOES show the program icon when the app is minimized and shown in the Windows main task bar WITH border/caption, but NOT without it. This seems very odd to me Confused | :confused:

I really want the program icon shown...
Solution:? Unsure | :~

Hmmmm. I just created a dialog based app using VC++ 6, removed the title bar and set the border style to none. I ran the program and promptly got the task-bar icon. Something else is the problem in your case.

Thx for your reply Nish.
But...I just created a dialog based app using VC++ 6, set style to 'popup' and the border style to 'none'. All the other fields but 'visible' are left blank.
I ran the program and did NOT get the task-bar icon.
I run under win98 4.10.98. Might that be the problem?

Mmmhhh ... so i tried following, and that´s really weird :

dialog based mfc app have an extra code in OnPaint() to draw the icon in the task bar, and this has to work no matter whether there is a caption or there is no caption. So i put a breakpoint into the onpaint method, and discovered that ... the IsIconic() method does not respond properly WTF | :WTF:

(return FALSE even if the app is minimized)!!! So there must be another piece of code which draws icons in the task bar...

I´ve copied the code in a OnButton method (because without border there is no minimialize button, so i´ve created one), so that i have :

void CTestDlg::OnButton() 
{
	
	ShowWindow(SW_MINIMIZE);
	
	WINDOWPLACEMENT* lpwndpl=new WINDOWPLACEMENT;
	GetWindowPlacement(lpwndpl);
	CPaintDC dc(this); // Gerätekontext für Zeichnen

        SendMessage(WM_ICONERASEBKGND, (WPARAM) dc.GetSafeHdc(), 0);

	// Symbol in Client-Rechteck zentrieren
	int cxIcon = GetSystemMetrics(SM_CXICON);
	int cyIcon = GetSystemMetrics(SM_CYICON);
	CRect rect;
	GetClientRect(&rect);
	int x = (rect.Width() - cxIcon + 1) / 2;
	int y = (rect.Height() - cyIcon + 1) / 2;
	// Symbol zeichnen
	dc.DrawIcon(x, y, m_hIcon);
}

and here the GetClientRect(&rect); returns {0,0,0,0} Confused | :confused:

!! So, I´m quite as lost as ViolaCase now Big Grin | :-D

. Can Someone explain how this minimize thing functions, and why the overrided OnPaint() method is not used ??

comboboxex with edit vs tooltip

real name11-Jul-02 23:18

real name

11-Jul-02 23:18

why my comboboxex doesn't show tooltip with mouse over editctrl? (cursor is edit's)
all difference i see comparing to another functional example is i have comboboxex, OnToolHitTest fills still absolutely the same, in calling function gets to TTM_ACTIVATE and HWND_TOP but nothing happens
(i tried when is over edit return edit's or comboboex's id etc. but all failed)
all is fine when mouse is not over edit resp. when i open it without edit (CBS_DROPDOWNLIST only)
has someone this problem?

I've been looking at Memory Leak detectors and I've found this one 'Memory Sleuth 3' by Turbo Power. You can get a trial version here ...

http://www.turbopower.com/trialrun

They say 'Trial-Run Editions of TurboPower products are fully-working versions of our software. The only restriction is that your compiler's IDE is running. In other words, you cannot deploy your applications with the Trial-Run Editions.'

This sounds pretty handy to me, am I missing the catch?

Just in case anyone missed me going on about Memory Detectors recently, I found this one called GlowCode which I realy like, and you can get a free time limited trial here ....

http://www.glowcode.com/update.htm

If you are looking for this kind of tool too, try them and let me know what you think, because I can't decided which to choose.

Have you looked at the one Software Verification advertise on CP ? I got a copy for winning the C# screensaver contest, and while I've not had a chance to look at it too deeply, I'm impressed with what I have seen. I believe Rama won one as well, and so did James, maybe ask them also.

I seem to recall you are in the UK, and they are too, so that's probably a plus as well, in terms of support.

Hi,

I have seen some rulers designed by VC++, but is there a
ruler designed as a timecode (hour, minute, second and frame,
with 1 second = 30 frames)?

Did you have any purpose or ideas?

Thanks in advance!

How to use MFC CDialog in a DLL ?

Yo Yo~~11-Jul-02 21:31

Yo Yo~~

11-Jul-02 21:31

Hello, folks,

I got some trouble using MFC CDialog class in my DLL (MFC static linked DLL).
Though my DLL is made MFC static linked, when I use MFC classes to create a dialog (pop-up or child), I always got a window creation error.

I know I can create dialog using win32 SDK (i.e, using CreateDialog(..) or DialogBoxParam(..), I did them before !), but I still want to use MFC to create my dialog. Because I also have something like CListCtrl or CListView on that dialog.

Could anybody help me ? Or I should use win32 SDK instead ?
And, are "list control" and "list view" same ?

Any response would be appreciated.
