I've always done it in OnCancel and OnOK as I described, but I thought OnKeyDown would work. If not, the you'll need to override PreTranslateMessage and supress the keyboard messages altogether.

Yeah overriding PrepTranslateMessage() is exactly the way that solves my problem. Thanks alot for your enlightenment.

you can overload the dialog member function OnOk() and OnCancel().then i think you will deal with your problem.

Hello,
I am getting two linker warnings when I compile my dialog based program written in VStudio 6.0. I am using DAO connectivity in my program.
The warnings that I am getting are --
LINK : warning LNK4098: defaultlib "LIBC" conflicts with use of other libs; use /NODEFAULTLIB:library
LINK : warning LNK4089: all references to "SHELL32.dll" discarded by /OPT:REF
In my project settings under Link Tab, I have following information --
kernel32.lib user32.lib gdi32.lib winspool.lib comdlg32.lib advapi32.lib shell32.lib ole32.lib oleaut32.lib uuid.lib odbc32.lib odbccp32.lib ddao35.lib ddao35D.lib ddao35U.lib ddao35UD.lib /nologo /subsystem:windows /incremental:no /pdb:"Release/TDMS2000.pdb" /machine:I386 /out:"Release/TDMS2000.exe"
Please advise how and if I need to change my project settings. Thanks !
Anjum.

aren't ddao35.lib and ddao35D.lib the release and debug versions of the same lib? you should only link to one of them, depending on the debug/release configuration of your project.

Hi,
I created a project using a CEditView .. If I press any key ( writing a text in CEditView) when I finish the application appear a Box asking if I want to save this text ( I think that this is because Serialization is actived ) .. Do you know how can I desactive this function ?
Tks a lot

Hello,
I am getting the strangest error. I have a VC++ Dialog-based
application using VC++ 6.0. At one point in my
application, if I press "Enter" the application just
quits. If I press anything else of click the button to go
on a next screen etc. .. it works fine. IF I press the "X"
on top corner to quit, it asks me if I want to quit and
quits normally. But if I press Enter on that screen it
just suddenly terminates, completely blimps out!!
I doesn't happen if I press space. If I press Esc then a messagebox comes and and asks me if I want to quit the application. ...
I do have OnOk() function over ridden. and when I press Enter, the application quits before it even enters the over ridden OnOk() function. I have changed the declaration of OnOk in my .h file in many different ways. I do not have an event handler explicitly declared for OnOk function.
It doesn't happen if the focus is on one of the buttons. Then that buttons click event gets executed. It doesn't happen if I set one of the buttons to be Default Ok .. then by pressing Enter that button gets executed.
But if I have focus on any text or combo box .. and press Enter .. it just terminates the application with no warning or message.
Please help. I will really appreciate any insight into
this. Thanks
Sincerely,
anjum Gupta.

You should override OnOK() not OnOk() (capitalization matters). This is covered in the VC forum FAQ.

Hi,
With a locally defined buffer, the following works fine: but I want to use doc variable to fill my list with, and it crashes:
if(NULL != m_list1.GetSafeHwnd())
{
CTrain1Doc* pDoc = (CTrain1Doc*) GetDocument();
char* pc;
CString string;
int nListIndex = 0;
for (pc = pDoc->m_buffer ; *pc ; pc = strchr(pc,0) + 1) //////crashes here in debug...
{
char* pc1 = strchr(pc,','); // search for a comma, returns a null pointer if not found
if (pc1) *pc1 = 0; // if we find a comma we replace it with a null character, if we didn't find a comma then the word is already null-terminated
string = pc;
int nItem = m_list1.InsertItem(nListIndex,string);
nListIndex ++;
}
}

You should call GetBuffer on a CString before accessing it like this.
Overall I would discourage you from using char * like this, you're better off using the member functions of CString ( if you must ) or std::string.
If you use std::string, I reckon you could write a function object to do this more nicely.

Hi.
I began to start MFC Windows programming via Jeff Prosise close to seven months ago. I believe it is an excellent MFC reference for beginner MFC Windows programmers.
I am to the point where I have ideas about upcoming projects, but there are some uncertainties including MFC issues. I would like to know whether there is an intermiate to pro level MFC book? Please post recommendation only if are believe the book and author present information that are more advanced than that from Jess Prosise book. Information could including overriding key MFC classes and functions. So basically, I am looking at a look that could help you begin modifiying MFC to whatever you want.
Thanks,
Kuphryn

MFC Internals is a good book, if a little dated. You should probably just download some MFC extensions from a web site, if you can find one that offers such a thing :P. Have a look at some code on CP and read some articles here, is my advice. Although MFC's days are most certainly numbered IMO.

Got to agree with Christian's recommendations.
MFC Internals is a good book for finding out what's going on inside MFC. Also reading the MFC source code will give you an excellent starting point.
Downloading code from CodeProject will also help to give you an understanding about what is and isn't possible.

Thanks.
I have read reviews of MFC Internals at Amazon. I many reviewers recommend Programming Windows with MFC before going with MFC Internals. I think it is just about right to study from MFC Internals.

In my view class I did GetClientRect and got a height of 334.
I went over to my mainframe class, got a pointer to the activeview and did
pView->GetClientRect(&rect);
This was so bizzare, but I got 504 instead!!! FRom looking at the view, 504 is more accurate, but why did I get two different heights? The view I'm looking at is active, so I have the right pointer.ANy ideas why?
Thank you very much,
Very puzzled,
ns

It's not wierd at all - one is the size of the view, the other the size of the frame. The frame includes the non client area of the view, the menu, the toolbars, etc.

I'm missing something!
I did pView->GetClientRect(&rect);
which is to say get the views client area (not plain old GEtClientRect which would be the frames area), so as I understand it,
getting the height in view and storing it in a variable to give to mainframe is the same as getting the rect with the pointer to the view.
Am I lost in a haze of confusion here? I do so want to understand your response,
Thanks,
ns

In that case, I dunno. You're sure both functions were called at the same time, or when the view was the same size ? It's not an MDI app and they were two different views ?

Its an MDI app with 2 views but when I'm doing all this, the second view isnt even spawned. I'll be puzzling over this I guess....
Thanks so much for answering though! Have a good weekend!

If I want to set a member variable of my inactive view from the mainframe class, how do I get a pointer to it? I was doing GetActive View but that obviously wont work if my view is inactive. Thanks,

if you have a pointer to your doc, you can use CDocument::GetFirstViewPosition (and GetNextView) to get a list of all your views.

The only way i saw to get a doc pointer from the mainframe calss was to go through activeview->getdocument which is I suppose what i have to do, to get to the inactive view. Is this correct?
Luckily Ihave only two views. What is the heirarchy of views, what is the order and how do I know when I've got to the one I want (in case I had 4-5 views?)
Thanks so much for the response,
ns

you can always use the IsKindOf function to tell the class of each CView pointer you get:
if (pView->IsKindOf( RUNTIME_CLASS( CMyView ) ) )
{
...
}

I have a menu item "Display" that has COMMAND handled by the mainframe. I want a menu item "Switch" handled in my view, to disable "Display". I am thinking that I could set a flag in my "search" menu handler, and in the automatic updateUI that runs when idle, disable or enable the "display" menu. Any commments on the soundness of my approach?
Thanks,
ns
