Do you mean the "parent of a tree control" or the "parent of a node in a tree control"?

(item's parent) of (a tree control),
|
|
|
|
|
In that case ... if you're using CTreeCtrl, you need to call GetParentItem and pass it the handle of the item (HITEM) you want to know the parent of. It will return the item handle of the parent item, or NULL if it doesn't exist.
If you are using raw Win32, you need to use Treeview_GetParentItem and pass it the window handle (HWND) of the tree control and the item handle of the item you want to know the parent of. It will also return the item handle of the parent item, or NULL if it doesn't exist.
Hope this helps

I am wondering what class to use to have a toolbar appear when a child window is created in a MFC MDI application. I want it so that the main window contains a child frame and a floating toolbar. Thanks.

Hi
I just wanted to create a dll that works together with the Internet Explorer (the so called BHO-Browser Helper Object)
I created the file as described here: http://www.microsoft.com/mind/defaulttop.asp?page=/mind/0598/browhelp.htm&nav=/mind/0598/inthisissuecolumns0598.htm
In Debug mode, the dll compiles quite fine, but if I choose to compile in Release-mode (ReleaseMinSize or ReleaseMinDependency), I get one linker error:
unresolved external symbol _main (translated from german)
why the hell does my dll not compile, although it does in debug mode? 
regards

remove the _ATL_MIN_CRT preprocessor macro from your release projct.
|
|
|
|
|
it works
thanks a lot

Look at Q165076 in the knowledge base. You may need to remove the _ATL_MIN_CRT preprocessor define if it is present in you release configuration. This is often the cause of unresolved external errors in ATL .dll's. You will find this in the Project Settings dialog, C/C++ tab, the preprocessor selection in the dropdown.
Hope that helps,
Aaron

You'll have to override PreTranslateMessage in CYourDlg. Inside the function, call ::TranslateAccelerator.
BOOL CYourDlg::PreTranslateMessage(MSG* pMsg)
{
if (::TranslateAccelerator(m_hWnd, m_hAccelTable, pMsg))
{
return TRUE;
}
return CDialog::PreTranslateMessage(pMsg);
}
Init m_hAccelTable in OnInitDialog - call LoadAccelerators.

I am interested in understanding how to change the capture resolution of a webcam without using the property pages (i.e., dialog boxes). I want to be able to set this in my program independently of the dialog boxes. Does anyone know how to do this? I am using the DirectShow interface for capturing. Any help would be appreciated.
Thanks,
John

Hi,
I am developing activeX control in VC++.
My control is built with usage of two other OCX files so I pack three OCX files and INF file in one single CAB file.
It is being placed on the web page with CODEBASE tag and class id of my control.
It works fine but I need to get USER_LOGON to verify user's permissions to access database (this is INTRANET application)
to get user login I am using VBScript:
<%
full_user_id = Request.ServerVariables ("LOGON_USER")
Response.Write full_user_id
i=InStrRev(full_user_id,"\",-1,vbTextCompare)
if i>0 then
user_login = Right(full_user_id,len(full_user_id)-i)
else
user_login = full_user_id
end if
%>
and i get the proper string in 'user_login'
the question is - how can I pass this user_login variable to my C++ code ?
i would guess by setting :
<param name="web_user_name" value="<%" response.write="" user_login="" %="" />>
Am I on the right track ? Does anyone know how to pass USER_LOGON variable from the html page to activex control's code (VC++) ?
thank you

You could set a property in your ActiveX and use JavaScript or VBScript code to assign it at the HTML side, but it isn't a good way to do that.
This is my advice!...
In the HTML page you could use the PARAM tag of your ActiveX like this.
<object id="YourActiveX" classid="CLSID:11111111-2222-3333-4444-555555555555" viewastext="">
<param name="USER_LOGON" value="user_login" />
...
At your VC++ ActiveX code, all you have to do is to create an internal member variable, for example "CString m_sUserLogin"
In the method,
void DoPropExchange(CPropExchange* pPX) {
// ...
// all you have to do is to append the next line
PX_String(pPX, _T("USER_LOGON"),m_sUserLogin, _T(""));
}
Ok, that's it!
I hope it solves your problem.

I have a CTreeView and a member m_TreeCtrl which is of CTreeCtrl type.
Everytime I use m_TreeCtrl.DeleteItem() to remove an item from the tree, all of the items will be collapsed automatically!!!
Have any of you met this problem? How could I solve this problem?
Thanx in advance.

No, I haven't set the TVS_SINGLEEXPAND. Here is the code:
if (!m_TreeCtrl.Create( WS_VISIBLE | WS_CHILD |
TVS_HASBUTTONS | // Adds a button to the left of each parent item.
TVS_HASLINES | // Has lines linking child items
// to their corresponding parent items.
TVS_LINESATROOT | // Has lines linking child items to
// the root of the hierarchy.
TVS_EDITLABELS | // Allows users to edit the labels of tree view items.
TVS_SHOWSELALWAYS,// Causes a selected item to remain selected when
// the tree-view control loses focus.
rc,
this,

Thank you!
