how can I know if I can put my grid control in charge of loading the data it needs?

i don't know what you're using for your grid, but some of the standard Windows controls allow this. for example, the CListCtrl can act as a "Virtual list control", which means it will send you a message when it needs data for an item. the MSDN has info on this.

Do I have to perform a new query each time?

ideally, you would cache some data.

SWDevil wrote:
Also - won't this solution take a lot of time also? isn't the solution of loading page by page better?

you're only ever loading, at most, the number of lines you can display at once, so the control will load faster and won't be required to maintain a large amount of memory to hold all the items.

PrintWIndow Problems (black squares)

Hi.

I´ve made a screen capture code using the PrintWindow function, been my input parameter the window handle I want to capture. This window has some buttons, labels, ... that as you may know act as child windows for the first.

It all works fine, mostly, but every 500 or 700 grabs I get one or two of them where child elements appear as black rectangles.

I've read [1] about something like this when child windows style is CS_CLASSDC or CS_PARENTDC. Obviously, I do not create the windows I capture, so I can't change that style.

So, I don't know how to face the problem. Maybe a PrintWindow alternative, but I need independence of the z-order (deep) of the window, getting a clear capture even if the window is not foreground.

Thanks in advance.

But GetClientRect() only gives the client area size of the window i want the whole page size of the html document i.e with the scrollbars also.

Supposing you actually need the full size of the HTML document, including the parts out of client area, a possible solution can look like this:

CComPtr< IHTMLDocument3 > doc = (IHTMLDocument3*)GetHtmlDocument();
IHTMLElement * doc_element;
doc->get_documentElement(&doc_element);
CComQIPtr<IHTMLElement2> element = doc_element;
long width;
long height;
element->get_scrollWidth(&width);
element->get_scrollHeight(&height);

Please note that the sizes are available only for fully loaded HTML documents, when GetReadyState() returns an appropriate value.

Hope this is what you need in your HTML-capturing application.

Hi,

I have a program coded in vc++6 and ms access as the database.The data connection is done using DAO.

Suppose I run this program on a computer that does not have microsoft office installed, will it still work? i.e. will it still be able to connect to the database?

If not, will installing the microsoft jet engine be sufficient?

Thanks,
Tara

You dont need to install MS Office, but you have to install MDAC. Jet engine will come as part of MDAC.
