You don't need all this code (not professional) to play GIF files in Windows.
Animated GIF is native with Win32 COM SH interfaces (used by IE...)

Could someone direct me to a source of information on how is F1 key processed in "standard" MFC application. I would like to intercept other function keys to change focus to various controls in CFormView derived view. I have been experimenting with PreTranslateMessage and OnHelpInfo but need some guidance here.
Thanks for you help
Cheers Vaclav

There is some information concerning context-sensitive help support of MFC on MSDN. You may want to examine MFC source files like winfrm.cpp, winfrmx.cpp and apphelpx.cpp for CFrameWnd and CWinApp classes.

You may use accelerator table resources to intercept other keys like F1 below.

IDR_MAINFRAME ACCELERATORS PRELOAD MOVEABLE PURE 
BEGIN
    VK_F1,          ID_CONTEXT_HELP,        VIRTKEY, SHIFT
    VK_F1,          ID_HELP,                VIRTKEY 
END

You may also benefit from mnemonic keys for form controls.

SOLVED MFC and F1 help using PreTranslateMessage [modified]

Found a solution thanks to the forum using PreTranslateMessage in CFormView. Also found Q222829 article very helpful but confusing. Is it really necessary to run TranslateAccelerator ? Also I do not see why Accelerator resource is also in the picture.

Addendum - Apparently it is necessary to use TranslateAccelerator and other functions when the accelerator key is in menu.

I am including (for review only – it is redundant) two ways to retrieve the VK_F2 (function key F2 ) , they both accomplish same result.

Of course the de-reference symbol is as always “->” and not “-&gt;”. I really do not know why, but is it not my mistake!

Thanks guys Vaclav

BOOL CFD2008View::PreTranslateMessage(MSG* pMsg)
{
     // TRACE("\n BOOL CFD2008View::PreTranslateMessage(MSG* pMsg) ");

   if (m_hAccelTable) {

             {
         if(pMsg-&gt;wParam==VK_F2)
               {
                    TRACE("\nBOOL CFD2008View::PreTranslateMessage(MSG* pMsg)   VK_F2");
                    m_edit.SetFocus();

               }
            return(TRUE);
             }

         }
   }

     if(pMsg-&gt;message == WM_KEYDOWN)
     {
                 if(pMsg-&gt;wParam==VK_F2)
               {

Alias an Array of Pointers

Skippums17-Jun-09 11:00

17-Jun-09 11:00

Hello. I would like to create an alias to an array of pointers, but don't know the syntax for such an operation. For example, to create an alias, "b", to an integer, "a", I would do the following:

int a;
int &b(a);

Here changing either b or a also modifies the other. However, how do I do this if the type of a is an array of double* const, as in the following:

double* const a[2];
double* const (&b)[2](a);

Is the second line doing what I want it to, and creating an alias for a? If this is not correct, does anyone know how to do this? Thanks,

Sounds like somebody's got a case of the Mondays

The way to make it easier to parse (by you, not the compiler!) is to split the type definition from the reference declaration:

typedef double* const MyArrayType[2];

MyArrayType a = { whatever };

MyArrayType& b = a;

Simpler, no?

Whenever you're responsible for allocating/deallocating resources.

Which (for my programs, at any rate) is 90% of the time.

For COM, use _com_ptr_t (in the guise of COM_SMARTPTR_TYPEDEF). For BSTR, use _bstr_t. For 'normal' pointers, use Boost smart pointers[^].

ATL Server Web Service on Vista / IIS 7 and VS2005

Hi There !!!
Let's find someone who could help me on this problem.

I have created on VS2005 under Windows Vista a new Visual C++ ATL Server Web Service Project with:
Blob Cache
Session Services (Memory-backed session-state service)
I compiled the project sucessfully. Then, i opened IExplorer and access de URL to generate the WSDL.
The WSDL of the web service was generated with sucsess.

This is my problem:
With this simple and basic project, i changed the configuration properties to support Common Language Runtime Suport, Old Syntax (/clr:oldSyntax)
The compilation of the project was made successfully.
The problem was when i go to access the web service to generate the WSDL via web browser.
I access the URL (something like: http://localhost/ATLWS1/ATLWS1.dll?Handler=GenATLWS1WSDL) on IExplorer, and the web browser hangs and no result is returned.
Just a page indicating that "Internet Explorer cannot display the webpage".

There some dependency or configuration missing to support CLR ?? I tried the same scenario on Windows XP and this works fine.

User detailes from Outlook

Hi All,

I am working on a project with MFC and i need one of my windows to display the user detailes(First Name, Last Name, WorkPhone and Personal Phone) who logged into the computer. I Can use MAPI or CDO for this, access the address book, iterate thru the users and get the detailes.

Is there a way that i can use to identify the current user address book detailes instead of iterating thru the address book.

Some sample codes will help me.

Thankyou,
Kasi

here i have a clue. but not sure weather it suits your requirement.
take the scroll bars outside your control,
in the on hscroll and on vscroll events, or on hitting the arrows,
increment/decrement the co ordinates of the image wrt. the control appropriately.
i remember, long back, when i had to display a big city map on my dialog,
i had to do the same thing for panning and zooming the map.
good luck.

You better use scrollbars in a scrollview. (it is complicated enough)
