Have you taken a look at the "Returns" and "Diagnostics" sections of the Docs for SQLFetchScroll[^] function? What is the return value, and if it is a failure, what does the diagnostics reveal?
The solution to your issue may be right there.

Hi Every one.
actually It's the first time I use CSpinButtonCtrl in Visual Studio 2008 sp1
But it seems that it's not working with it's buddy control (in fact it does not do anything)
, here is my code in OnInitDialog() method, any Idea if I forgot something here!
CSpinButtonCtrl* pSpinCtrl = (CSpinButtonCtrl*)(this->GetDlgItem(IDC_SPIN1));
pSpinCtrl->SetBuddy(GetDlgItem(IDC_EDIT_SPIN_BUDDY));
pSpinCtrl->SetRange32(10,500);
pSpinCtrl->SetPos32(20);

pSpinCtrl->SetPos32(20);
I don't see any problem with your code. Did you forget to set the "Set Buddy Integer" property of the spin control to true? If not, try that. Additionally, I would recommend that you add a control type member variable to your edit box (the buddy control), say m_Edit and add a control type member variable to the spin control as well (say m_Spin). And then rewrite your code like this:
m_Spin.SetBuddy(&m_Edit);
m_Spin.SetRange(10,40);
m_Spin.SetPos(12); This way, you could avoid the casts, avoid an extra pointer variable, and avoid GetDlgItem[^]

for your information...i'm very new for VS C++ programming..
the program i want to try create program like this:

i want to know either i can create program like this using MFC???

Then I strongly suggest to buy a good book about the MFC and start to learn from the basics. You won't achieve a lot if you don't have at least a basic understanding of the MFC. And learning through a book is usually much faster than asking help from people.

This is a fairly basic question with many samples around, take a look here[^], as a starting point.

Hello Everyone,
This is my 2nd Post regarding the Text extraction from the WebPages.
In my Previous post David Crow suggested me use IHTMLDocument2 interface,
In the code project depository I found this application
Parsing HTML using MSHTML [] by Philip Patrick ..Extracts all the links in the WebPages Using HREF Tag,
Can I use the same application to extract the Text from the Table from the WebPages ?
I searched for Table tag from which I can extract the text, I did not find any information. Can anyone please tell me is it possible to use MSHTML using IHTMLDocument2 interface can I extract the Text from the <table> Tag.
Thanking you,
Naveen HS.

Hello Sir,
Thank you very much for the response.
I have added this lines to the above code.
MSHTML::IHTMLDocument2 *pDoc1 = NULL;
MSHTML::IHTMLElementCollection *pColl = NULL;
pColl = pDoc1->get_all(L"table");
int y = pColl->length;
for(int x = 0; x < y ; x++)
{
}
i am getting the following Error :-
error C2664: 'MSHTML::IHTMLDocument2::get_all' : cannot convert parameter 1 from 'const wchar_t [6]' to 'MSHTML::IHTMLElementCollection **'

This is wrong.
get_all will give you all elements and not all tables.
get_all takes the IHTMLElementCollection pointer as the parameter.
As a general rule, all COM calls in C++ will return an HRESULT.
Except maybe AddRef and Release.
So you will have to check the tag name in a loop to see if they are tables.
So the get_all call would look like this -
pDoc1->get_all(&pColl);
I would recommend using ATL here.
Otherwise you will have to remember to call Release for all these pointers.
So my recommended way would look like this -
CComPtr<MSHTML::IHTMLElementCollection> pColl = NULL;
pDoc1->get_all(&pColl);
You can use the IHTMLElementCollection::item[^] method to get an IDispatch pointer to each element in the collection.
This can in turn be QIed to an IHTMLElement[^] or IHTMLDOMNode[^] interface.
Check the methods of the interfaces to identify the table tags that you need.

Hello Sir,
Thanks a lot for the reply.
I made changes as mentioned by you, but still i am not able to extract the data from the table. can u please tell what change i have to make.
MSHTML::IHTMLDocument2Ptr pDoc;
MSHTML::IHTMLDocument3Ptr pDoc3;
MSHTML::IHTMLElementCollectionPtr pCollection;
MSHTML::IHTMLElementPtr pElement;
HRESULT hr = CoCreateInstance(CLSID_HTMLDocument, NULL, CLSCTX_INPROC_SERVER,
IID_IHTMLDocument2, (void**)&pDoc);
pDoc3 = pDoc;
pDoc->get_all(&pCollection);
pCollection = pDoc3->getElementsByTagName(L"table");
for(long i=0; i<pCollection->length; i++){
pElement = pCollection->item(i, (long)0);
if(pElement != NULL){
m_wndLinksList.AddString((LPCTSTR)bstr_t(pElement->getAttribute("table"),10));
}
}
Error :- error C2660: 'MSHTML::IHTMLElement::getAttribute' : function does not take 1 arguments

The syntax for getAttribute is not correct.
Do it this way -
CComBSTR name("table");
VARIANT result;
pElement->getAttribute(name, 0, &result);

Hello sir,
I added the code , still getting the error.
pDoc->get_all(&pCollection);
pCollection = pDoc3->getElementsByTagName("table");
CComBSTR name("table");
VARIANT result;
for(long i=0; i<pCollection->length; i++){
pElement = pCollection->item(i, (long)0);
if(pElement != NULL){
m_wndLinksList.AddString((LPCTSTR)bstr_t(pElement->getAttribute(name, 0, &result)));
}
}
I am getting the below error :-
error C2660: 'MSHTML::IHTMLElement::getAttribute' : function does not take 3 arguments
