Right-click on the Dialog class that contains the spin control. In the window that appears, select the IDC of the control you want to receive notifications about, in the "Class or object to handle" listbox.
UDN_DELTAPOS should appear, along with NM_OUTOFMEMORY, in the "New Windows messages/events" listbox on the left hand side.
There you go!
Sliders receive both the WM_HSCROLL and WM_VSCROLL messages. You can either handle them in the control itself, or through the parent dialog.
The kindest thing you can do for a stupid person, and for the gene pool, is to let him expire of his own dumb choices.

Hi,
I want to create 4 radio buttons of which two form one group and other two form another group on a dialog.I should be able to select one button from each group(i..e two buttons in total).How can I do this?

You need to set the windows style WS_GROUP on the first radio button in each group, and make sure that the tab order has each pair together.

Lay out your dialog.
Select every control on the dialog.
Set the WS_GROUP flag.
Set the tab order so that the buttons in each grouping follow each other.
Select all the buttons in one group, except the first.
Clear their WS_GROUP style.
Repeat for second grouping.
Test, Enjoy, read up on WS_GROUP.
Iain.

Hallo!
I have to export analysis-data from a MFC-application to an Excel-Sheet. I use Excel 2000 (Version 9) and have created several classes to make data-exchange within C++. To write the data into the sheet is not the problem, I´ve got the problem to send an Excel-formula from the application to the Excel-Sheet in several ranges. I tried to send a simple formula with the code below. The result ist that the string appears in the cells in Excel but isn´t executed automatically. I tried other ways, too but nothing happened or errors were given. Has someone experience in sending and executing formulas from MFC/C++ to an Excel-sheet? I would be very happy! Thank you.
VARIANT vVar;
long index[2];
DWORD numFields[2];
COleSafeArray saCell;
m_oBooks=m_oExcel.get_Workbooks();
m_oBook=m_oBooks.get_Item(COleVariant((short)1));
m_oSheets=m_oBook.get_Worksheets();
m_oSheet=m_oSheets.get_Item(COleVariant((short)1));
...
m_oRange=m_oSheet.get_Range(COleVariant("A3"),COleVariant("D3"));
m_oRange=m_oRange. get_Resize(COleVariant((short)1),COleVariant((shor
t)(4)));
numFields[0]=1;
numFields[1]=4;
saCell.Create(VT_BSTR,2,numFields);
index[0]=0;
index[1]=0;
vVar.vt=VT_BSTR;
csStr.Format("=WENN(A2=0;1;99)");
vVar.bstrVal=csStr.AllocSysString();
saCell.PutElement(index,vVar.bstrVal);
m_oRange.put_Formula(COleVariant(saCell));

When I'm using a class derived from CSocket in a class derived from CWinThread
the CMyClass::OnReceive(nErrorCode); does not triger.
Can someone explain the reason in some other projects it trigers.

Hello,
I want to save a Message(such as an EMail or maybe it must be an EMail) in the Inbox(or in a folder that is under the inbox) of Outlook whithout sending it as an EMail.
I have to do it in C++.
I have created wrapper-classes by using the typlibraries from outlook 2000...
Please send me help.
Thanks a lot,
JohnX

Since you've created a wrapping, I'm assuming you have looked through what's available. Basically, just create a new item of the appropriate type (any type of item, be it standard or custom with the correct form associated). Get a reference to the Inbox folder (several ways are possible using the namespaces). Then just add the item. This is possible with any folder.
I don't have any code samples since I haven't done this in a long time but the idea is still the same and it works. The Inbox is still just a folder, so just add the item to it.

To create an new item is not the problem.
My problem is who can I get a reference to the inbox folder.
There are no documentations ! How can I do this ?

Using Outlook's type library:
COleVariant vtOptional((long) DISP_E_PARAMNOTFOUND, VT_ERROR),
vtTrue((short) TRUE);
_Application app;
_NameSpace ns;
MAPIFolder folderInbox;
if (app.CreateDispatch("Outlook.Application") == TRUE)
{
ns = app.GetNamespace("MAPI");
ns.Logon(vtOptional, vtOptional, vtOptional, vtTrue);
folderInbox = ns.GetDefaultFolder(6);
}

i don't want a dialog box to be displayed..

it doesn't work out if the outlook window is not opened..
how to solve it..i tried using new sesion also..anddd..logon ui also..
it doesn't work!

Then use:

even when use the new session..
am able to read the mails only one at a time!
and also....

the fourth parameter being the pointer to the message identifier seed..
i'm [passing as Nul in the beginning to read the first unread mail..
how should i use it later??
