Hello Thomas

I notice your response to Eric with some code snippets after I posted my
initial reply. :-) I¡¯m starting to build an Outlook 2000 environment to
test it. Based on my experience, Thomas, I feel the problem may lie in your
code line:
hIcon = theApp.CRL_GetIcon(lIcon, CRL_ENABLED | CRL_SIZE_SMALL);
What¡¯s your implementation of CRL_GetIcon?

Below is a workable example of Copy2clipboard for Outlook 2000. I wrote &
tested it when I was dealing with the thread mentioned in my last reply. I¡¯ve
also attached its project to this reply, and you may download it with
Outlook Express or Windows Mail.

Good morning, Thomas. Welcome to office.developer.com.add_ins newsgroup!
My
name is Jialiang Ge [MSFT].



I once handled a very similar issue, where a customer said his
CommandBarButton icon cannot be shown only in Outlook 2000. That problem
turned out to be caused by the code:

HBITMAP hSrcBmp = LoadBitmap(AfxGetResourceHandle(),

MAKEINTRESOURCE(IDB_BITMAP1));

The method LoadBitmap has been superseded by the LoadImage function
because
it is incompatible with some device context. Thus, the resolution was to
replace the line with:

HBITMAP hSrcBmp = (HBITMAP)::LoadImage(GetModuleHandle(NULL),

MAKEINTRESOURCE(IDB_BITMAP1), IMAGE_BITMAP,0,0,LR_CREATEDIBSECTION);



Thomas, because you did not mention how you loaded the bitmap icon or
provided any code snippet for test, I cannot quickly figure out the reason
for this specific issue. But I suggest you read the above-mentioned
thread:

http://office-outlook.com/outlook-fo...60/#msg_209360



And if the thread does not help, would you please show us some code
snippets? I'd be very happy to test it for you.

Hi all,

I have a problem with an Outllok AddIn.

Our AddIn creates a CommandBar and adds some buttons to it.
Depending on the context of the user actions (ie which message type is
highlighted, is a contact highlighted..) some buttons
are enabled or disabled. This runs flawlessly on most of our customers
enviroments.
We now have one customer where the following problems occur:

On some or most buttons the icons are missing. The button is there and
can
be used, but there is no icon.
We have a 'restore Toolbar' option in our settings dialog wich, under the
hood, removes all buttons from
the CommandBar and then adds them again. Interstingly, after each hit on
the restore-button, a different set of
Icons is displayed on the CommandBar until finally, after a non
deterministic count of tries, all icons are displayed.
This ist not quite the way we would like this to function.

The enviroment is Windows Server 2003, Terminal Server Mode, Citrix
Metaframe and Outlook 2000 SR3

Any hints are strongly appreciated...

Heallo Jialiang,

thanks for your extensive posts on my issue.

test it. Based on my experience, Thomas, I feel the problem may lie in
your code line:
hIcon = theApp.CRL_GetIcon(lIcon, CRL_ENABLED | CRL_SIZE_SMALL);
What¡¯s your implementation of CRL_GetIcon?

We use a resource dll for whitelabeling the application which implements
the function like this:

extern "C" HICON CALLBACK CRL_GetIcon(DWORD nID, DWORD dwFlags)
{
// Tell MFC to use our own resources not those of the loading module
// (must be used for every exported function that loads resources).
#ifdef _AFXDLL
AFX_MANAGE_STATE(AfxGetStaticModuleState())
#endif

// Size?
INT cx = CrlGetSize_(dwFlags);

// Enabled or disabled icon?
LPCTSTR pszName = MAKEINTRESOURCE(dwFlags & CRL_DISABLED ? nID +1 : nID);

// Note that LoadImage() does not require a subsequent DestroyIcon() in
Win32.
// Important: If the icon can't be found, return the icon 'empty' to avoid
// program crashes when returning NULL as HICON.
hIcon = (HICON)LoadImage(
AfxGetResourceHandle(),
pszName,
IMAGE_ICON,
cx, cx,
LR_DEFAULTCOLOR);

// LoadImage fails to load 128x128 icons on some Win9X systems, so use the
64x64 as fallback.
if(!hIcon && (cx == 128))
hIcon = (HICON)LoadImage(
AfxGetResourceHandle(),
pszName,
IMAGE_ICON,
64, 64,
LR_DEFAULTCOLOR);
if(!hIcon)
hIcon = (HICON)LoadImage(
AfxGetResourceHandle(),
MAKEINTRESOURCE(IDI_CRL_MISC_UNKNOWN_ID),
IMAGE_ICON,
cx, cx,
LR_DEFAULTCOLOR);

// LoadImage fails to load 128x128 icons on some Win9X systems, so use the
64x64 as fallback.
if(!hIcon && (cx == 128))
hIcon = (HICON)LoadImage(
AfxGetResourceHandle(),
MAKEINTRESOURCE(IDI_CRL_MISC_UNKNOWN_ID),
IMAGE_ICON,
64, 64,
LR_DEFAULTCOLOR);
return hIcon;
}

The main difference in our handling seems to be that we load the icon
as an icon first and convert it to a bitmap afterwards.
We chose this approach to use a generic way to load the icons.
Maybe there is a fault in this conversion...

Hello Thomas,

In fact, my code was written by referencing the VB code in the KB article
http://support.microsoft.com/kb/288771/en-us. It demonstrates how to create
a transparent picture for Office CommandBar buttons. But because your code
is importing an icon, instead of a bitmap resource, I suggest you read this
KB article:

How To Add a Transparent Icon to a Toolbar Button
http://support.microsoft.com/kb/260850

It provides the workable way to copy icon to bmp for Outlook 2000 system.
Though the sample code is in VB, the calls of API are the same in VC.

Hello Thomas

I'm writing to check whether the icon-bmp conversion method in my last
reply help you or not. If you need my help to translate those VB code
(http://support.microsoft.com/kb/260850) to VC, please let me know.
