In exactly the same way you would in any other application.

After you've got a DSN created (see here for an example), use ClassWizard to derive a class from CRecordset.

PostNcDestroy() question

ns3-Apr-06 2:57

3-Apr-06 2:57

I have

CDialog::PostNcDestroy();

m_pParentWnd->SendMessage(UDM_LISTCLOSED,0,0);

delete this;

and in the .h file

// Overrides
	// ClassWizard generated virtual function overrides
	//{{AFX_VIRTUAL(CTargetInfo)
	public:
	virtual BOOL OnInitDialog(); // called first time after construct

	protected:
	virtual void DoDataExchange(CDataExchange* pDX);    // DDX/DDV support
	virtual void PostNcDestroy();

	//}}AFX_VIRTUAL

The dialog was created by:

if(!m_tgtInfo)
{
    m_tgtInfo = new CTargetInfo(this, caseStudy);
    if(!m_tgtInfo) return true;
    m_tgtInfo->Create(IDD_DLGTGTINFO, (CWnd*)this);
    m_tgtInfo->ShowWindow(SW_SHOW);
}

When I close this modeless dialog, execution does not enter the PostNcDestroy function. However if I close the whole app, then the code does go into this function. What am I missing? I looked at sample code and there does not seem to be anything else I need to do... Confused | :confused:

thanks,
sb

Switch these two statements.

Have you called m_tgtInfo->DestroyWindow()?

When am I supposed to call m_tgtInfo->destroyWindow()? The user closes m_tgtInfo at which point I was trying to send a message to the parent (which instantiated m_tgtInfo)
thanks for helping,

When you want to dismiss the modeless dialog.

A miscommunication, I think.
The user closes the m_tgtInfo dialog using the system menu at the upper right corner (the cross). I don't dismiss it with code. Am I still missing your point? When the cross is clicked, I thought the postNcDestroy() function would run, but it doesn't. Thanks for your patience.

Do you have the following:

void CTargetInfo::OnOK()
{
    DestroyWindow();
}
 
void CTargetInfo::OnCancel()
{
    DestroyWindow();
}
 
void CTargetInfo::OnClose()
{
    DestroyWindow();
}

And when you will find a job and that you will be asked to do something, will you also ask people to do the job for you ?

Start working on your homework, and when you get stuck, come back here and post SPECIFIC questions.

Hi 0300
This is not the proper way to ask. We all are here to help each other.
As Cedric said whenever you stuck to any problem and don't find the solution you can post your queries. No one here is going to provide the full source code.

So first start yourself .

Hi 0300
for another modes
you should fisrt start to write your program and then asked a question
or if you have a problem.

after openning a file one of my friend told me that use the following steps:

1) declare an _bstr_t variable say bstr in your CDocument
2) then, bstr = m_pIDomDoc->xml;
3) then, in the OnDraw method, write

CYourDocument* pDocument = (CYourDocument*)GetDocument();
CString xml (pDocument->bstr);
pDc->DrawText(xml, 0,0 );

first step is ok.
but what abt second step.where i have to write this line & what is xml.
Please tell me.
