Re: A question about Microsoft DataGrid Control, Version 6.0(OLEDB) IsaacLitingjun13-Dec-04 14:09 IsaacLitingjun 13-Dec-04 14:09  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! Best Wishes, --------------------------- You will when you believe! ------------------------ Re: A question about Microsoft DataGrid Control, Version 6.0(OLEDB) *Dreamz13-Dec-04 17:13 *Dreamz 13-Dec-04 17:13  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"... Re: A question about Microsoft DataGrid Control, Version 6.0(OLEDB) IsaacLitingjun13-Dec-04 18:44 IsaacLitingjun 13-Dec-04 18:44  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!

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....
