Hi All,
I want to enumerate menu item identifiers of MS-Office apps. I found all MS-Office apps share resources stroed in some dll (MSO.dll, may be wrong). I like to disable some menu items by using subclassing or something else. So can anybody help to enumerate these id's.
Thanks a lot!

STDMETHODIMP TestMacroInterface::ProcessStringArray(SAFEARRAY**ppOutputArray)
{
HRESULT hresult;

aDim[0].lLbound = 0;
aDim[0].cElements = 3;
aDim[1].lLbound = 0;
aDim[1].cElements = 2
BSTR HUGEP *pbstr;

Change this to,
SAFEARRAYBOUND aDim[3]
aDim[0].lLbound = 0;
aDim[0].cElements = 3;
aDim[1].lLbound = 0;
aDim[1].cElements = 3
aDim[2].lLbound = 0;
aDim[2].cElements = 3
BSTR HUGEP *pbstr;
*ppOutputArray=SafeArrayCreate(VT_BSTR , 3, aDim);
if (*ppOutputArray==NULL)

Hi all,
I want to develop add-in for OUTLOOK, In that for event handling use IDispEventSimpleImpl Interface, and declare handler function (fn) for the specified event using SINK_ENTRY_INFO, but whenever that particular event occurs my handler function gets call two times! why it happens so? I want to call it only single time....
MY code is.....
class ATL_NO_VTABLE CConnect :
public CComObjectRootEx<ccomsinglethreadmodel>,
public CComCoClass<cconnect, &clsid_connect="">,
public IDispatchImpl<addindesignerobjects::_idtextensibility2, &addindesignerobjects::iid__idtextensibility2,="" &addindesignerobjects::libid_addindesignerobjects,="" 1,="" 0="">,
public IDispEventSimpleImpl<1,CConnect,&__uuidof(Outlook::ExplorerEvents)>,
{
public:
BEGIN_SINK_MAP(CConnect)
SINK_ENTRY_INFO(1,__uuidof(Outlook::ExplorerEvents ),0xf002,onFolderChange,&OnSimpleEventInfo)
END_SINK_MAP()
public:
//type defination to avoid compilation 'ambigous call' errors
typedef IDispEventSimpleImpl<1,CConnect, &__uuidof(Outlook::ExplorerEvents)> ExpEvents;
void __stdcall onFolderChange();
}
Any idea about this, please suggest me...
Thanks & Regards,
Shyam

Hi,
I have a component in vb.net. In this component i have app.config file from which I am reading the connection settings and settings for enterprise libarary exception handling.
If I use this component form .NET application it works fine but when I try to use this component from asp by registering the dll, the copmponent is not able to read any settings from app.config file.
Please provide solution to this problem i searched everywhere but not able to get the working solution.
|

|

To my knowledge a DLL cannot have app.config
because app.config is only for individual applications (like windows / console)
i.e. it should not be a DLL
however a DLL can read ....
for example : 1. sum.dll is reffered in math.exe
2. then sum.dll can read from app.config of math.exe
3. sum.dll cannot have it's own app.config.

Hi, all!
I have a following problem, and i can't find a right solution.
Description:
There is a COM server written on C++ and it works through IDispatch and it does't have a TYPELIB. And from another side there is a COM client developed on C#. Through LATE BINDING it uses a COM server
and COM server sends different events to client, but i can't implement COM event handling mechanism.
Please, anybody can help me?!
Thanks in advance!

If you have a look in the registry below HKEY_CLASSES_ROOT\CLSID\{<clsid of the server>}, does it contain a key named 'TypeLib'?
If not, do you have an .idl file where the interfaces of the server are defined?
"It's supposed to be hard, otherwise anybody could do it!" - selfquote

maybe you could check whether server app contains typelib using vs2005 ,like wlm.

Hi all,
I am been having trouble with finding an answer to this question but here goes:
Is there any way to write to MSWORD without automation through ASP.NET in C# (maybe write to an existing word document without opening it)?
I am pulling my hair out! I have tried adding IUSR, ASPNET to the web server, I have tried Identity Impersonate = True in the web.config.
My code for opening word looks like this:
object isVisible = true;
object readOnly = true;
I get a Macro storage error on the open statement. I have put a lot of time into figuring this out and I really dont want to do a TOTAL 180.
wordDoc = WordObj.Documents.Open2000(ref fileName, ref missing, ref readOnly, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing, ref isVisible);
I appreciate any ideas or suggestions given!

I have a Local Server created in MFC. It displays a modal dialog with a "logout" button. It also contains a COM coclass "A" to which clients are connected. Everything works fine till all clients follow proper reference count rules.
But if a client terminates abnormally, then this coclass "A" has an outstanding reference count on Local server. When user clicks "logout" button, the application dialog closes but the server continues running in background because of this outstanding reference count.
I understand that when the proxy no longer exists in this case, the stub will do a cleanup automatically but after few minutes.
But the requirement is to force the application to shutdown completely when "logout" button is clicked. I have thought of few ways to do it, but I would like to know your thoughts on this so I can choose the best possible solution.
Thank you for your time.
