Hi,everyone. i'm a newbie of VC,i'm sorry if the question bother you（actually it's the second time）...
Here it is:
when i first added the component Microsoft DataGrid Control, Version 6.0(OLEDB), and added a member variable to a class by Class Wizard.i got the following dialog:
"The ActiveX Control "Microsoft DataGrid Control, Version 6.0(OLEDB)" has not been inserted into the project. Developer Studio will do this now and generate a C++ wrapper class for it."
but I didn't do it rightly, so I wanted to delete it. (I think i must delete it in a wrong way and left something!) I navigated to the variable in the header file, and I deleted it.
when I tried to reinsert the variable (once again by using Class Wizard, and choosing Add Member Variable), the former dialog didn't come out,instead, "Add Member Varible" dialog appears and the varible type datagrid1 exsits and i can't use it properly. i have searched in files i can't find string "datagrid" anymore,why does the compiler remember that
it seems the compiler has remembered my option and would't like to give me another choice 
i don't know how to do,and hope someone can help me,Thank you so much!
Best wishes,

At first, i would like to Thank you so much! Dear *Dreamz. You're so kind!
as you said, i checked the DoDataExchange funtion in Dialog' cpp,here it is:
--------------------------------------------------------------
void CStepbystepView::DoDataExchange(CDataExchange* pDX)
{
CFormView::DoDataExchange(pDX);
//{{AFX_DATA_MAP(CStepbystepView)
//}}AFX_DATA_MAP
}
--------------------------------------------------------------
i think no "datagrid" or something else related i don't know how to do,,, could you tell me the next step? Thanks!

When you create a member variable the declaration will come in the Class' .h File and a reference ( like this .. DDX_Control(pDX, IDC_DATAGRID1, m_datagrid1) ) will be there in the DoDataExchange function.
Still i couln't get what can be the problem..
Can you try to delete the varible by the "Delete Variable" button in the "Add Member Variable Dialog"...

At first,Thanks again!
when i now create a new project and do as following steps:
1. Insert ActiveX control: Microsoft DataGrid Control, Version 6.0(OLEDB);
2. Use classwizard bind the IDC_DATAGRID1,and a dialog come out:
"The ActiveX Control "Microsoft DataGrid Control, Version 6.0(OLEDB)" has not been inserted into the project. Developer Studio will do this now and generate a C++ wrapper class for it."
and then i can find :
CFormView::DoDataExchange(pDX);
//{{AFX_DATA_MAP(CStepbystepView)
DDX_Control(pDX, IDC_DATAGRID1, m_datagridctrl);
//}}AFX_DATA_MAP
in DoDataExchange function.
but i don't know the project now i'm running, i Insert ActiveX control but that dialog ""The ActiveX Control "Microsoft DataGrid Control, Version 6.0(OLEDB)" has not been inserted into the project. Developer Studio will do this now and generate a C++ wrapper class for it." didn't come out
maybe because i have added CDataGrid1 class manually before? but now i searched DataGrid in files,i find nothing, i don't known
Thank you again for your help! this question has puzzled me for a long time!
hope to hear good news!

Once you have added the classes this messagebox wont come again...

By default wizard will give you the class name as CDataGrid.Did you change that?

Please check whether all the files are added to your workspace.Else you can add them from the working folder...
Could you add the member variable...??

Delete all the newly added files for the DataGrid from your workspace and from the current working folder...
Delete the include for datagrid.h and Rebuild all...
Open the Project' .dsp file in a notepad.Towards the end of the file there will be some entries for the newly added files for the DataGrid.
eg:
# Section CPTest : {CDE57A43-8B86-11D0-B3C6-00A0C90AEA82}
# 2:21:DefaultSinkHeaderFile:datagrid.h
# 2:16:DefaultSinkClass:CDataGrid
# End Section
Delete all those sections for the classes that we deleted..
Rebuild All...Now do what you want..You will get "Your Message" dialog..
Note:
Dear Dick.lee Solucky...
This is what i tried by created an application like yours...
I am not sure that this is a right way or not...
So if you use this,please make a copy of your application and proceed...please..
I could build the application without any error....
Good Luck

this is tougher time:
my project is using Carlos's ado class,
http://www.codeproject.com/database/caaadoclass1.asp[^]
and now my problem is: i can't find my problem!
Hi, *Dreamz, you know it's you give me strength to ask a question again! i really wanted to give up again(i'm ashamed of that! ), but recalling all your efforts! i think i should continue to battle! ![Rose | [Rose]](https://codeproject.global.ssl.fastly.net/script/Forums/Images/rose.gif)
but this time i really don't know where the problem is!
last time, i thought it's because i added datagrid class in a wrong way, so it din't work, but following your way,i have that dialog and added the class in the right way, but i still can't use this ActiveX control properly.
all things go well when i created a new project,
i just want to share ,,, Thanks! i even didn't know how to ask a question
do u have any suggestions? or i leave my msn, and we talk there?
dick_ltj@hotmail.com
Thank you again!

You must be the man God send you to help me!
Now I can describe what happened: I hope maybe can help you to find the problem out: 
When I delete the Microsoft DataGrid Control, Version 6.0(OLEDB) from my dialog CDataBindDlg, and select in the menu,
//////////////////////////////////
CDataBindDlg databinddlg;
databinddlg.DoModal();
//////////////////////////////////
And the dialog can come out, and if I insert BreakPoint here :
//////////////////////////////////
BOOL CDataBindDlg::OnInitDialog()
{
CDialog::OnInitDialog();
<-- BreakPoint
…
//////////////////////////////////
It can run here.
--------------------------------------------------------------------------
But when I added the Microsoft DataGrid Control, Version 6.0(OLEDB), then I select in the menu, nothing happened, dialog didn't come out,
And also program didn't stop at my breakpoint,
I don't know where the problem is
following code can run properly in my new build project,it's the code to bind Recordset to DataGrid
////////////////////////////////////////////
CString strConnection = _T("Driver={Microsoft ODBC for Oracle};Server=tzcenter;Uid=voice_call;Pwd=voice_call;");
//strConnection = _T("Driver={SQL Server};Server=sysdevpdc;Trusted_Connection=Yes;Database=sysDev;uid=sa;pdw=");
if(m_pDb.Open(strConnection))
{
m_pRs = CADORecordset(&m_pDb);
if(m_pRs.Open("t_ywdm_576", CADORecordset::openTable))
//if(m_pRs.Open("sysTable01", CADORecordset::openTable))
{
m_datagridctrl.SetCaption("Clients");
m_datagridctrl.SetRefDataSource(NULL);
m_datagridctrl.SetRefDataSource((LPUNKNOWN)m_pRs.GetRecordset());
m_datagridctrl.Refresh();
}
}
else
{
AfxMessageBox(m_pDb.GetLastErrorString());
DWORD dwError = m_pDb.GetLastError();
//
return FALSE;
}
//
return TRUE; // return TRUE unless you set the focus to a control

just mean i created a dialog and do nothing, of course it will show when i use "databinddlg.DoModal()"
But when i added the Microsoft DataGrid Control, Version 6.0(OLEDB), dialog didn't come out, and the program also didn't run to -> CDialog::OnInitDialog(); i don't know where it stopped ...
i guess there are some problems of the initialization of Microsoft DataGrid Control, Version 6.0(OLEDB)
