I need to scroll the CFormView derived view to the top of the form. When I use OnScroll with SB_TOP the form scrolls only one line up after each ESC key press. However, using SendMessage function works just fine.
Am I doing something wrong? (VC 6.0)
Yes, I was not reading "fine print"!
As always please ignore the dereferencing symbol, it is actually "->".
Any constructive comments are appreciated.
Cheers Vaclav
if(pMsg->message == WM_KEYDOWN)
{
if(pMsg->wParam==VK_F2)
{
TRACE("\nBOOL CFD2008View::PreTranslateMessage(MSG* pMsg) VK_F2");
m_edit.SetFocus();
}
if(pMsg->wParam==VK_ESCAPE)
{
TRACE("\nBOOL CFD2008View::PreTranslateMessage(MSG* pMsg) VK_ESCAPE");
ShowWindow(SW_HIDE);
int iPos = 0 ;
SetDlgItemText(IDC_EDIT1,"");
C_ResetCompletionFlags();
SendMessage(WM_VSCROLL, SB_TOP,0); // works OK
OnScroll(SB_TOP,iPos,TRUE); // scrolls one line up only
ShowWindow(SW_SHOWMAXIMIZED);
m_edit.SetFocus();
}

The first parameter of OnScroll() is composed of two parts; a low-order byte for horizontal scrolling, and high-order byte for vertical scrolling.
For vertical scrolling to top, you should use like that.
OnScroll(MAKEWORD(0, SB_TOP), 0, TRUE);
But. if the form has horizontal scrollbar, you will have another problem because of design of that function. SB_LINEUP or SB_LINELEFT is defined as 0. And the function runs in both direction at one whack. That means 0 in high-order byte will be interpreted horizontal line left at the same time. So, you will have unwanted left scroll with above call.
You may have to call again to keep the horizontal position unchanged.
OnScroll(MAKEWORD(SB_LINEDOWN, 0), 0, TRUE);
However, top for both direction will work well.
OnScroll(MAKEWORD(SB_TOP, SB_TOP), 0, TRUE);
Or if there is no horizontal, there won't be any problem.
Otherwise, IMHO, SendMessage(...) way is more appropiate.

Can't you use web browser control [^]for rendering HTML in your MFC application?
If you're trying to have a core rendering engine, you can use Webkit [^] Open Source rendering engine.

Thank you for your reply.
In a word, I want to develop an application like Klipfolio dashboard where I have multiple HTML control areas in which content is updated via C++ which talks directly to JAVASCRIPT which in turn talks to HTML.
I solved the issue of C/C++ - Javasccript communication via this module : http://www.mozilla.org/js/spidermonkey/[^]
But still unable to do all the chain.
In case you do'nt want to download and test Klipfolio, this is screenshot I uploaded to my gallery. You can see how the application renders content as HTML and and is able to intercept its events and acts on it too from the host C++ application.

Can I acheive that with Webkit ?

Our software has some fields where users enter email addresses. We don't actually send any email. A later process picks up those email addresses and sends out notices.
Bad email addresses with things such as spaces, quotes, or double '@' signs can cause serious problems for the system sending out the notices, so we are already validating for some of those things.
But we want to tighten up our validation of the email addresses as much as possible when they are entered. We're not going to go as far as trying to determine if they are valid addresses, but at least want to confirm that they are of valid 'format'.
We're not certain what all of the rules are, but someone here had the idea of tapping into Outlook. I was playing around with calling CMapiSession::Resolve() on the email addresses, and it appears that an address gets 'resolved' if it's of valid format, even if it's not in your Address Book, so exactly what we need. (Of course it will also resolve a name or id that's found in your address book, so need to either make sure there's also an '@' symbol, or replace the name with the email address for them).
But, here's the thing that I find slightly annoying. That little dialog that pops up asking the user to "allow access" to their Outlook. I would love to avoid that, and again, since we aren't actually sending an email, and don't even really need to access their Address Book, it seems like we should be able to avoid asking for access. We are only trying to make use of Outlook's validation of address format, not the part that actually tries to resolve whether it's in their address book.
Does anyone know if it's possible to separate out that functionality? Or find and swipe that chunk of code??? We'd like to make sure our format validation is consistent with Outlook's validation.
Other suggestions also welcome...
Thank you.

Ummm - leave MAPI - just use a regex[^]. Or this one[^] on CodeProject.
Or you could look at the definitive standard[^]?

No, useless.
Simply use the api from MS Acc DLL to validate email address (1 line of code...)

Hello
I am working on VS 2003 and getting compiler warnings saying that those 2 above mentioned functions are depreciated. I know VS 2008 they have sprintf_s and other more safer functions. But there's no way for me to upgrade to 2008.
So can anyone tell me how to get those compiler warnings go away, without setting the warning level to low priority.
That is, i would like to use a wrapper around the sprintf function which will do the type checking to make sure the buffer is of valid size.
Is there any function like that i can use VS2003?
Any help is welcome.

If the compiler is telling you they are deprecated, then is it also telling you what to use instead? I find it hard to believe that the compiler would know enough to complain, yet not provide any means by which to correct the problem.
In any case, you might have to use _CRT_SECURE_NO_WARNINGS.

Hi,
you probably know the signature and functionality of the safe functions; why wouldn't you start using them: implement them yourself, it only takes a couple of lines of code to come up with something that satisfies the interface and is a lot safer than the old unsafe stuff.

StringCchCopy()[^] is a safer alternative to sprintf. You will need to #include "strsafe.h" and link to strsafe.lib.
You might want to take a look at String functions[^]

You just need to download the latest SDK. Can't you?

Rajesh,
Is this function a replacement for sprintf, strcpy , strcat? I mean, is there similar replacement fuctions?
Also am not sure whether i will be able to download latest SDK, unless its free from Microsoft.
Do you think this will satisfy the compiler?
I know that if i use sprintf_s in place of sprintf, the compiler will be happy. But unfortunately my working environment is VS2003 and there is no way of updating to 2008.
Do you know of any wrapper for sprintf, which will do the similar kind of work that sprintf_s will do? So that i can make sure that i will sprintf only once.

Did you read my reply or not? I clearly mentioned that StringCchPrintf is a replacement for sprintf and it is a secure function. Please read it properly again. I also gave you a link to a set of string functions that are safe, which you should have a look at.
If you try to use any of those functions, you will know what it does.
SDK is free for download and the latest one is available here: http://www.microsoft.com/downloads/details.aspx?FamilyId=F26B1AA4-741A-433A-9BE5-FA919850BDBF&displaylang=en[^]

You should report the line, as it is (and probably more relevant code), in order to get any help.

Thank you very much for replying my question. I found out the problem.
It is wired. I add one file from firebird DLL project to my app project. Then everything works.
Best regards,
