Re: GlobalRealloc big problem ....

2-Jul-03 3:00

GlobalRealloc() does not necessarily return the same memory handle as the one passed to it - it's value may change. You need to store the new value:

eyeConClients[msg - SOCKET_ID - 1].buffer = GlobalReAlloc((HGLOBAL)eyeConClients[msg - SOCKET_ID - 1].buffer, szTemp, GMEM_MOVEABLE);

If you need to cast your buffer to a HGLOBAL, you will need to cast the return value of GlobalRealloc() to make it fit with your buffer variable. You didn't say what type it was, so I don't know what to cast it to - you'll need to do that.

Hope this helps,

you need to change value of registry key
HKEY_CURRENT_USER\Software\Microsoft\Windows\
CurrentVersion\Policies\explorer\NoDriveTypeAutorun
to (DWORD) 0x0FF disable
or (DWORD) 0x095 enable autoplay

Just to supplement what skaanji said...

For the NoDriveTypeAutorun variable, each bit in the value represents a type of drive. A bit set to '1' disables autorun for that drive type, '0' enables it.

Bit 0 = Unknown drive types
Bit 1 = Drives without a root directory
Bit 2 = Removeable drives (floppy, zip, jazz, etc.)
Bit 3 = Fixed drives (hard drives)
Bit 4 = Network drives
Bit 5 = CD/DVD drives
Bit 6 = RAM drives
Bit 7 = Reserved (always set to 0)

Hope this helps,

Ryan

Dear skaanji and Ryan Binns:
At first, Thanks a lot for you. You have said is correctly. But Because I have a little about register. So maybe it is difficult. Can you give me a example about it? I saw some about Enabling and Disabling AutoPlay articles in Microsoft MSDN. It's tittle is "Enabling and Disabling AutoPlay" . It seems that maybe have other method. Can you see the article for me. I am expecting... Hmmm | :|

welcome to meet you!

I don't think that there is any other way so you need to change the registry but this is what I use:
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\CDRom]
"Autorun"="0" // 0 disable, 1 enable
I also agree with the other posts that suggest that you should not change user settings unless you let them know what you're doing.

It is a VERY BAD IDEA to change people's registry. Look in MSDN for "disable autoplay" and it tells you a way to do it while your program is running without changing people's registry.

I'm going to patent thought. I have yet to see any prior art.

If this is your own computer I would change the registry however if this is a product you should not mess with the user settings in the registry unless you at least inform the user of what you are doing and allow them to cancel your change.

Hi, Sir:
I saw your answer about disable CDROM autoplay function . and I think so that It is a very bad idea to change people's registry. And I have sawn the "Enable and Disable AutoPlay" in MSDN. I do it that:

UINT g_uQueryCancelAutoPlay = 0;
BOOL DialogProc(HWND hwnd, UINT uMsg, WPARAM wParam, LPARAM lParam)
{
switch (uMsg) {
...
default:
if (!g_uQueryCancelAutoPlay)
{
g_uQueryCancelAutoPlay = RegisterWindowMessage(TEXT("QueryCancelAutoPlay"));
}
if (uMsg == g_uQueryCancelAutoPlay)
{
SetWindowLong(hDlg, DWL_MSGRESULT, TRUE);
return 1;
}
}
}

but I can't success. Can you tell me How to do it? I wish to get your reply? Thanks

Does anyone know how to change the standard view in the MDI project with a Property sheet (wizard style)?

You can find a class 'CPropertySheetView' here[^] at CP.
But I have no idea if it can be used as a Wizard.

My opinions may have changed, but not the fact that I am right.

hi
Just declare a member variable of your propertysheet class in the view class, override OnInitialUpdate, create the member propertysheet as a child.

void CMdiView::OnInitialUpdate() <br />
{<br />
	CView::OnInitialUpdate();<br />
<br />
	CMySheet *m_pMySheet = new CMySheet("foooo");<br />
<br />
	m_pMySheet->Create(this,WS_CHILD|WS_VISIBLE,0); <br />
	<br />
}

best wishes..mil10

Salut,

Regarde les CPropertyPage et les CPropertySheet, cela te permet de gérer un tabctrl.
Tu crées ton CPropertySheet et dedans tu mets autant de CPropertyPage que tu as besoin.

Hello,

Inside a formview, i've got the reader activex :

- Is it possible to remove some of the icons of the toolbar from the pdf.ocx in order to customize it ?
I've tried with the registry but i have always the entire toolbar.

- When i gave up this solution, i succeded to simulate the some of the standard icon (text capture, image capture ...) with windows messages.
That's fine on all the os but i have some problems on XP.
Sometimes it works and sometimes not, certaily a problem with the windows message due to XP ?

Anyone has an idea ?

Thanks.
