Call GetDeviceCaps(hdc, LOGPIXELSX) on any device context that refers to the screen. You can use GetDC to get a device context for a given window.

This was answered for you more than once. Once here by Rick York, once here by me, and once here by Mike Dimmick. What part are you not understanding?

Help me! Blimey!
When my CDialog, which contains 3 CListCtrls, is first minimized and later restored the lists are gone away in the case there was an update of the lists during the minimizing time. I have tried to manual invalidate,redraw (-items),update the lists and also the whole dialog by catching the restore event in OnSysCommand - but nothing works. I can reenable the lists in two ways: 1. automatic with the next update, 2. manual change the content of the lists with a button with some filter action in the background. As an ugly workaround i also tried to simulate this manual action by direct calling of the functions but that also doesn't work - i must do an mouseclick. Befor the next step is to simulate that mouseclick (i hope no one will ever see that), i hope somone can help me with right action for that case. !
Greetings

and

do the same... but what do they do??

Dunno if that'd been answered before, but looks to me like it'd disable the keyboard. Do I get a prize?

CListCtrl controle
Look for CListCtrl::ModifyStyle(....) for values
LVS_SORTASCENDING : for sorting in ASCENDING order
LVS_SORTDESCENDING : for sorting in DESCENDING order
and remove both property to disable sort

I would try to use CListCtrl::ModifyStyle too, but by playing with the style LVS_NOSORTHEADER instead.

Hi all.
I am embedding media player 6.4 in my MFC ActiveX control.
It can successfully be used in any app.
Problem: (happens in XP only it seems)
When I embed my control in a web page, it works, but when the page is unloaded, or iexplore is closed, the application crashes and says:
Unhandled exception in IEXPLORE.EXE (WMPDXM.DLL): 0xC0000005: Access Violation.
The last code I can get to is:
File: comip.h
void _Release() throw()
{
if (m_pInterface != NULL) {
---> m_pInterface->Release(); <----- Here. line 662
}
}
If I release the IMediaPlayerPtr m_pPlayer; I got using QueryInterface:
IUnknownPtr pUnk;
pUnk = m_Player.GetControlUnknown();
pUnk->QueryInterface(IID_IMediaPlayer,(void**)&m_pPlayer);
like this: m_pPlayer->Release();
myself, then it crashes on this line.
I am using VC6 on xp.
This question belongs to the COM forum, but since it seems dead.
Thanks for your help.
this is this.

Something is better than nothing.
In the destructor, I used this hack.
try
{
m_pPlayer = NULL;
}
catch(...)
{
}
Instead of m_pPlayer->Release().
Ok, I know this is real bad code, but it seems to work. The release version does not crash, neither does debug version.
HeHe.
this is this.

Hello!
Is there a way to keep the mouse from moving in a particular direction? Here's my situation:
I have a dialog with two controls. I have a home-made splitter betwee the two controls (my splitter is simply a CRect that I create to fill the space between the two controls). I have minimum widths for each of the controls. When a minimum width for one of the controls has been reached, and the user still has the left mouse button down, I want to keep the mouse from continuing to move in the direction that would continue to make the window smaller.
Does that make sense? Basically, I only want the mouse to be able to go as far as the splitter can go (as long as the left button is still down).
Thanks!

Thanks God, no, AFAIK no software can stop your mouse from working. What you should do is to stop the splitter, but let the mouse run free.

MSDN:
The BlockInput function blocks keyboard and mouse input events from reaching applications.
That basically means that no input is received until (if you read further) the blocking state is removed by calling the function again. So the message that he is waiting for (the WM_LBUTTUNUP) or the messages that the mouse is moving into the other direction, don't arrive either.
So basically he disables the entire app and starts waiting for an event that will never arrive...
