i could use api hooks for CreateWindow and CreateWindowEx!
also for ChangeDisplaySettings and ChangeDisplaySettingsEx if the game changes the screen resolution.

i don't know if it also works with directx games, try it to be sure about this problem!

Hi,

I found a set of animated cursor on the web. It's cool. But how can we use them into a MFC Application?

Thanks

Everything's beautiful if you look at it long enough...

If they are installed, you can use the Mouse applet from Control Panel. Just click on the Pointers tab.

Thanks,

But is there a way to use such a cursor into a MFC App? For example, if a want to use that kind of cursor when it is over a button?

You can either load them from the file system or embed them as resources in your app.

List box containing CWnd derived class as item.

Is it possible ?

I have a complex UI component that I'd like to put in a list box.

I've been reading some of the articles, and none quite gave me the answer that I was looking for.

Most owner draw example I've seen are only drawing graphic things in the item's space.

Thanks.

I dont know if you can add Cwnd classes under listboxes, but you could give each instance of the class a unique ID which the list keeps track of.

ASSERT and Win XP

I have several uses of ASSERT throughout my application. When an assertion is thrown, windows XP invariably asks me if I wish to send debug information to Microsoft. This is getting annoying.

Is there anyway to configure XP to stop doing this?

problem with icon in a dll

Mazdak5-Jun-03 4:02

Mazdak

5-Jun-03 4:02

I am writing dll with ATL and I want to insert an Icon in my dll. So I add an icon in my resources(both 32*32 & 16*16) and in my .rgs file I put DefaultIcon = s '%MODULE%,1' . So it works well and I can see my icon in the place that I want in my program,now the problem is if I change my icon and edit it in my resources I it does not effect and it always show the old icon,even if I unregister my dll and rebuild my project and register it again it shows old icon. Any idea? (I use VC6)

Hi all,
How can I know the user close my program by the ruthless way: End Process? What message will Windows send when the user do that?
Thanks for reading and wait for the reply!

AFAIK, the OS will call the TerminateProcess[^] API call with a handle to your process, and there's no easy way of determining this. You see, the OS was designed so this could be the "emergency" way of stoppping a runaway, maybe malicious process. The most common source for users killing a process is some software that do not give them proper processing feedback nor allow them to properly abort it. Even if you could stop TerminateProcess, remember, the power plug is always near. Smile | :)

Thanks for your documents,
However, the problem is that my program must know when it will is terminated in order to show some suitable warnings or notices to the user!

CListCtrl question

Hi,

What is the notification being sent from the control when a user is resizing the columns ?

The one I usually use is the HDN_ENDTRACK mssage, but you only get this when the finish doing the re-size. You also may need to add this line to get the message maps entries generated by class wizard to work correctly:

m_ListCntl.GetHeaderCtrl()->SetDlgCtrlID(m_ListCntl.GetDlgCtrlID());

Otherwise the HDN_ENDTRACK's all get send with a control ID of 0, and you canbnot tell which came from which control and they also do not map properly unless you change the message map entry.

As long as its the parent window on the control the method should work. The only issue you may have is if you are creating the control yourself dynamically. In such cases you still need that line I mentioned, but just have to add the message map/function prototypes manually:

// meaage map
ON_NOTIFY(HDN_ENDTRACK, IDC_OF_LISTCONTROL, OnEndtrackListControl)

// function ptototype
afx_msg void OnEndtrackListControl(NMHDR* pNMHDR, LRESULT* pResult);

// function...
void CYourWnd::OnEndtrackListControl(NMHDR* pNMHDR, LRESULT* pResult) 
{
	HD_NOTIFY *phdn = (HD_NOTIFY *) pNMHDR;
	// TODO: Add your control notification handler code here
	*pResult = 0;
}

I got all the things you mentioned, but it still does not work.

Does it matter if my listCtrl is part of a splitter window.
My application is a File Manager like with a MainFram that has a TreeView on the left and and listview on the right.

Well, I ended up adding this entry in the message map to compensate for the 0 it sends

ON_NOTIFY(HDN_ENDTRACK, 0, OnEndtrack)

Thanks anyway,

CEdit and CSpinButtonCtrl

CodeBrain5-Jun-03 3:24

CodeBrain

5-Jun-03 3:24

I have a CEdit control and a CSpinButtonCtrl in a form view. There is no problem for me to connect them so that they work as buddies.
But now I have a special task that should be done. The spin button should look like it is connected to the edit control (UDS_ALIGNLEFT style) but it should not change the text in the edit control. So I only need the "visual connections" but not the "data connection".

Can this be done without using the CSpinButtonCtrl::Create method? I would like to use the exisiting resource with the form view and the 2 controls instead of creating and position them at runtime. So I think my probem is that the UDS_SETBUDDYINT is automatically set if I activate the autobuddy function in the resource editor.

Client control device context

Anonymous5-Jun-03 2:22

I use the following code to create a device context in
a static control being part of a CFormView window in
order to draw inside its clients area. This code is in
the OnDraw() method of a CStatic derived class (an instance
of this class in part of CFormView window and OnDraw() is
called in CFormView window OnPaint()).

CWnd* l_pWnd;<br />
l_pWnd = m_pParentWnd->GetDlgItem(m_dwParentId);<br />
CClientDC l_Dc(l_pWnd);

The problem is the following:
my picture is drawn also if its coordinates
are out of client control area. In this way, if my
input data are out of ranges my code paints also the
parent window area.

How can I avoid this problem ?
I'd like that, if picture coordinates are out of
range, it is not drawn !!!

Thanks a lot!
