Hi everybody
I have written an ATL 3.0 project including two sample classes named CAttachment & CAttachments. These classes have interfaces IAttachment & IAttachments in order. IAttachments has got a method named "Item" that returns a result of the type of IAttachment. But before returning the IAttachment, I want to call some member functions of the CAttachment class to setup the IAttachment properly. I know how to create the IAttachment interface, but I don't know how to have access to the members of the CAttachment from the Item method. I will be thankful if anybody replies to me.
Regards,
Roozbeh.

It's a hack but you could cast your IAttachment interface to CAttachment and call the methods you desire.
CAttachment a = (CAttachment)piAttachment;
a->SomeMethodNotExposedInIAttachment();
pi->SomeMethodExposedByIAttachment();
Note, this won't work outside your implementation project as outside callers won't have access to the CAttachment class or any of its members not exposed by the IAttachment interface.

How is the CAttachments object producing the interface IAttachment to return?
Presumably you must be making a CAttachment object somewhere, or do you have them already created and you're just holding a list of the IAttachment interfaces?

Ok, sorry for the simple subject and for possibly this simple question, but here is what I want to do:
How do I compile in VC++ 6.0 using the .NET\Vc7\INCLUDE versions of
\Microsoft Visual Studio\VC98\INCLUDE\xlocale
\Microsoft Visual Studio\VC98\INCLUDE\xlocnum
\Microsoft Visual Studio\VC98\INCLUDE\streambuf
\Microsoft Visual Studio\VC98\INCLUDE\xmemory
(how?)
I want to use the same files, except they are from:
\Microsoft Visual Studio .NET\Vc7\include
I also want to do this in only one project of a multiple project VC++ 6.0 workspace.
Thank you for the help.

Just havethe desired path .NET\Vc7\INCLUDE appear before the \Microsoft Visual Studio .NET\Vc7\include in your project "include" directory settings. There's "move up/down functionality in the prop page.

I am compiling in VC++ 6.0, but want to use
C:\Program Files\Microsoft Visual Studio .NET\Vc7\include\xlocale
C:\Program Files\Microsoft Visual Studio .NET\Vc7\include\xlocnum
C:\Program Files\Microsoft Visual Studio .NET\Vc7\include\streambuf
C:\Program Files\Microsoft Visual Studio .NET\Vc7\include\xmemory
When I compile in 6.0, the inclusion of
C:\Program Files\Microsoft Visual Studio .NET\Vc7\include
has no effect.
When I use the Studio IDE or look directly at the .DSP file, i don't see anywere that I can place the Studio.NET-Vc7 version AHEAD OF the 6.0-VC98 version of these files.
Any suggestion?
Thanks.

Do this Tools | Options. Find Projects | VC++ Directories. Change the order of the Include Files (select from the combobox at the upper right). Just move the desired directories to the top, even add new ones if you wish

Hi all,
I am currently doing a project where I need to be able to have a imaging framework.
Although the framework itself runs pretty smooth, the CPaintDC of MFC kills me.
The SetPixelV is extremely slow, so I want to use another way of doing this.
I know it is possible to create a CDC in memory, but how can I put a bitmap created from this CDC put on the surface a CWnd subclassed control?
Any suggestions?

Code snippet to help you (heavily edited and content deleted):
BOOL DoChart(CallContextObj *pCallContextObj)
{
CDC oMemDC;
CBitmap *pOldBmp;
CBitmap oBmp;
long lWidth = 300;
long lHeight = 200;
pCallContextObj->GetParameterValue("ChartWidth",&lWidth);
pCallContextObj->GetParameterValue("ChartHeight",&lHeight);
CRect oBmpSize(0,0,lWidth,lHeight);
oMemDC.CreateCompatibleDC(NULL);
int iOldMapMode = oMemDC.SetMapMode(MM_TEXT);
CWindowDC dcScreen(NULL);
oBmp.CreateCompatibleBitmap(&dcScreen,oBmpSize.Width(), oBmpSize.Height());
pOldBmp = oMemDC.SelectObject(&oBmp);
WORD wChartType = 88;
pCallContextObj->GetParameterValue("ChartType",&wChartType);
BOOL bRetval = FALSE;
char caHeaders[512];
strcpy(caHeaders,"Invalid Chart Type");
switch (wChartType)
{
case 0:
bRetval = DoLineChart(pCallContextObj,&oMemDC,caHeaders,oBmpSize);
break;
case 1:
bRetval = DoBarChart(FALSE,pCallContextObj,&oMemDC,caHeaders,oBmpSize);
break;
case 2:
bRetval = DoBarChart(TRUE,pCallContextObj,&oMemDC,caHeaders,oBmpSize);
break;
case 3:
bRetval = DoOpenHiLowCloseChart(pCallContextObj,&oMemDC,caHeaders,oBmpSize);
break;
case 4:
bRetval = DoPieChart(pCallContextObj,&oMemDC,caHeaders,oBmpSize);
break;
}
if (bRetval)
{
LPSTR cpBuf = pCallContextObj->GetOutputBufferPtr();
long lQuality = 75;
pCallContextObj->GetParameterValue("ImageQuality",&lQuality);
char caContentType[256];
long lDataSize = WriteImage(oBmp,cpBuf,pCallContextObj->GetOutputBufferSize(),caHeaders,(DWORD)lQuality);
if (lDataSize > 0)
{
pCallContextObj->SuppressHeaders();
pCallContextObj->GetMimeType("x.jpg",caContentType);
sprintf(caHeaders,"Content-Type: %s%sContent-Length: %d%s%s",caContentType,cpCRLF,lDataSize,cpCRLF,cpCRLF);
if (pCallContextObj->ServerSupportFunction(HSE_REQ_SEND_RESPONSE_HEADER,"200 OK",0,(LPDWORD)caHeaders) || ::GetLastError() == 10054)
pCallContextObj->WriteClient((LPVOID)cpBuf,(LPDWORD)&lDataSize);
*cpBuf = 0;
}
else
bRetval = FALSE;
}
oMemDC.SetMapMode(iOldMapMode);
oMemDC.SelectObject(pOldBmp);
oMemDC.DeleteDC();
onwards and upwards...

Hi..
I have problems with makeing a scale in GDI.
What i make is : I draw on a memory DC then BitBlt on a window..
I want to make 2 things :
1-Set the origin of the memory DC to lower left corner instead of upper left.
2-change the scale : for example when i call LineTo(hdc,0,10) it draws 100 PX for example not 10.
after drawing on memory DC I BitBlt on the window that may or may not has its coordinates systems changed.
can this be done using SetViewportExtand SetWindowExt?
thank you in advance

Will SetViewportOrg() or SetWindowOrg() help?

This sounds like a map mode issue. Check out SetMapMode().

thank you
SetMapMode() is not enough..
using it I can set the mapping mode to MM_ANISOTROPIC but then i must use SetViewportOrg() or SetWindowOrg() to set the scale ..
the question is how ?

Hello!
I have got task to write easy security tool for MS Windows 98. It must deny access to specified local CD-ROM device. I think one of the possible solution is to stop corresponding device driver on demand. So the question is: which win32 functions should i use for enumerating devices and stopping drivers? Or should it be done by other way? Or may be you know the right "search string" for MSDN or Google to find good explanation?
Sorry for my bad English.
Thank you!

You can do it with Windows Management Instrumnetation(WMI) classes. Search fot it in MSDN or google.

The Platform SDK has plenty of TAPI samples.
You can also try
http://www.julmar.com/samples.htm[^]
or search this forum for TAPI as there have been many similar questions answered.

I'm creating own file browser based on CListCtrl - report mode.
I need to display the same folder's icon as windows explorer do.
I'm using SHGetFileInfo() to get the image.
My problem is that (in Windows XP - not tested in older systems)
the image is displayed with ugly solid black shadow around icon, (my list control has white background)
where system displays nice gradual shadow of the icon.
But when I set this icon into icon static control, it is displayed correctly.
Code I use to create image list :
m_listImg.Create(16,16,ILC_COLOR32|ILC_MASK,0,10);
CBitmap bmpTmp;
bmpTmp.Attach(::LoadImage(AfxGetResourceHandle(), MAKEINTRESOURCE(IDB_FILELIST),
IMAGE_BITMAP, 0, 0, LR_CREATEDIBSECTION|LR_LOADTRANSPARENT));
m_listImg.Add(&bmpTmp, RGB(255,0,255));
SHFILEINFO fi;
SHGetFileInfo("C:\\",0,&fi,sizeof(fi),SHGFI_ICON|SHGFI_SMALLICON);
m_listImg.Replace(9,fi.hIcon);
Any ideas ?
Thank you !

I generally just use the shell's image list, rather than copying the images into my own. First, set the list control to use shared image lists (so you don't delete the shell's list!) by setting the LVS_SHAREIMAGELISTS style. Then:
UINT uFlags = SHGFI_USEFILEATTRIBUTES|SHGFI_SYSICONINDEX|SHGFI_ICON|SHGFI_SMALLICON;
SHFILEINFO sfi;
HIMAGELIST hIL = (HIMAGELIST)::SHGetFileInfo(_T("BogusFilename.dat"),
FILE_ATTRIBUTE_NORMAL, &sfi, sizeof(sfi), uFlags);
if ( NULL != hIL )
m_ListCtrl.SetImageList(CImageList::FromHandle(hIL), LVSIL_SMALL);
if ( NULL != sfi.hIcon )
::DestroyIcon(sfi.hIcon);
Then, just use the SHGFI_SYSICONINDEX flag in your call to SHGetFileInfo() to find the index into the shell's list of the icon you want.
Oh yeah, one more thing - make sure your program includes a manifest so that the new WinXP controls are used. Otherwise, they won't know how to handle alpha channels...

This is working, thank you !
But the problem is that i need to display not only system icons, but also couple of my icons, co I can't directly use system image list

I'll try to duplicate and then rebuild system's image list
Seems that CImageList::Create() will always create image list with 1-bit mask, which is not enough for alpha channel

Hi,
I just upgraded a portion of my code from int to __int64, everything looked fine but the only problem is that it looks like this data type could not be serialized.....
Anyone know a 64bit data type in MFC that can be serialized ?

error C2679: binary '>>' : no operator defined which takes a right-hand operand of type '__int64' (or there is no acceptable conversion)
