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.

ClipCursor() is used for this.

Check, Is this Api Help [BlockInput]

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...

I wonder if that functionality does not depend exclusively on the graphic driver, and is not part of the Windows API. Should it be true, you have no chance to write such an application, without using the API of the driver (if exists!). But perhaps someone else can confirm/contradict my guess.

Yes, I have deleted the body but I haven't deleted the header
Thanks in advance

Looks like you deleted your OnInitialUpdate function in the view class (CMyAppView), but didn't delete the declaration from the header file.

|

You're right
Thanks in advance

Are you using GDI+ ? You're trying to get the DPI settings for an image, or from a printer ?
