EXCEL registers each of his documents in ROT. Maybe, it's your case: you can enumerate all of EXCEL documents in ROT. PID is wrong way.

In above site(as suggested by superman) ,it is clearly written that EXCEL registers only one instance of EXCEL.EXE in ROT. The other instance can only be retrieved if names of workbooks are known.
Even in the same site, it is mentioned that for multiple instance refer the site:
http://support.microsoft.com/kb/190985
But as per my requirement I need to track all excel.exe's running in processes using MFC(No gui, only exe)application but not setting anything in EXCEL as mentioned in above site.
If you get any clue from above mentioned sites, please let me know.
Thanks in advance.

If you read the first page you link to, you have: However, because Office applications also register their documents in the ROT, you can successfully attach to other instances by iterating the ROT looking for a specific document, attaching to this document, and then getting the Application object from this document. For a code example of iterating the ROT and looking for a document name, click the article number below to view the article in the Microsoft Knowledge Base:...
You don't even have to reference each individual instance as all documents (from all instances of excel) is in the ROT. If you need the application object for a document, it's also there via the document object.

Hi,
We have used the same code as given in
http://blogs.msdn.com/oldnewthing/archive/2004/04/23/118893.aspx
to capture objects under mouse in timer.But we are facing memory leakage problem.
While debuging this code we got the point of leakage is in function
AccessibleObjectFromPoint.
We already using IAccesible::Release function and VariantClear to release memory
but still memory leakage is there.
Any one know ,how to release memory used after AccessibleObjectFromPoint is called.
Please help.
Thanx in advance.

The leak could be from accessing a member function of IAccesible and not freeing its output parameter like the SysFreeString in the link.
You should consider using ATL classes like CComPtr[^] which is a smart pointer and do not need to be released.
Some other useful ATL classes are -
CComBSTR[^]
CComVariant[^]

Hi,
Thanx for reply.
Actualy we had removed all IAccessible function calls to clear that doubt,So now there is only one function call in timer that AccessibleObjectFromPoint() ,But still there is a memory leakage.
If you have any knowledge regarding this please let us know.
Thanx again,

Hi. I call my own external function from html:
my.html
var data = "";
data = window.external.MyOwnDhtmlFunction();
In derived class CMyDhtmlDlg:
1.
CMyDhtmlDlg()
{ EnableAutomation(); }
2.
STDMETHODIMP CMyDhtmlDlg::GetExternal(IDispatch **ppDispatch)
{
*ppDispatch = GetIDispatch(TRUE);
return TRUE;
}
3. BOOL CMyDhtmlDlg::OnInitDialog()
{ SetExternalDispatch(GetIDispatch(TRUE)); }
4.
BEGIN_DISPATCH_MAP(CMyDhtmlDlg, CDHtmlDialog)
DISP_FUNCTION(CMyDhtmlDlg, "MyOwnDhtmlFunction", MyOwnDhtmlFunction, VT_BSTR, VTS_NONE)
END_DISPATCH_MAP()
Its all ok in windows xp sp2 ie 6.0. I can call MyOwnDhtmlFunction from html. But its doesnt work in windows xp sp1 ie. 6.0.  How can i make it work in win xp sp1 under ie 6.0. And one more thing, what are the system requirements for CdhtmlDialog ? Can i use it in windows NT sp6 with ie 6.0 ?

Hi all... in my application i want get the original GetInfoTip() text, after it i want edit and show the new modified Text.
Now i use IQueryInfo for "hook" the GetInfoTip() function and work very well, but i must rewrite all file information tip text myself.. I have added:
NoRemove *
{
NoRemove ShellEx
{
{00021500-0000-0000-C000-000000000046} = s '{MYKEY}'
}
}
It's for all file and i have some trouble for reset the InfoTip text... any mode for get original default?
I have tryed this code:
IShellFolder* shFolder = NULL;
IQueryInfo* pInfo;
LPITEMIDLIST pidl = NULL;
SHGetDesktopFolder(&shFolder);
SHILCreateFromPath(file, &pidl, 0);
if (SUCCEEDED(shFolder->GetUIObjectOf(NULL, 1, (LPCITEMIDLIST*)&pidl, IID_IQueryInfo, NULL, (void**)&pInfo)))
{
pInfo->GetInfoTip(0, &pwszTip);
pInfo->Release();
if (pwszTip)
{
MessageBox(NULL, pwszTip, NULL, MB_OK);
}
}
But it still show the tip text of My Computer icon
Thanks in advance.

Did You check this code for any other type of files (.cpp, .h or anything else) ?
May be Shell does not analyze registry entry *.

Our company has an created an ActiveX control using Visual Basic 6 that allows users to view TIFF images in a web page. When Office 2007 is installed, the error "component not correctly registered" shows up when this web page is loaded and the ActiveX control calls the AsyncRead function. We do not see this error when other versions of Office are installed; it will work just fine with Office 2000 and Office 2003. Also, the applications in Office 2007 do not need to be running for this error to occur.
I have tried removing the control from the Downloaded Program Files folder and downloading it again, but I am still getting the same error.
Any help would be appreciated.

|

Does the control have any dependency on any of the office components?
If so you may need to release a separate version of your control that works with Office 2007.
Otherwise try and install (register) your control after installing Office 2007.

I think your ActiveX control has dependency on Office 2003 Web component 1.1..If so then you need to update your ActiveX com.

i need to create a web interface to control (enter the multicast address, set playlist,start/stop streaming) the multicast settings of the windows media services, in server 2003.so that an admin can log in from any machine in the network and control the main streaming server.
it is for my project and its very urgent.
can anyone help me we it?some tell me to go with a COM, but i have no idea how to do it.any alternatives?please, im desperate.
thank you

Hi All,
now I get connected in my main.cpp file to the server. I hope this will be correct. But how can I get now an event from the server? The server sends some events. I can see that because an Message Dialog will be opened from the server.
Now my questions are the following:
a)
Is the code until now correct? Is it possible to make a test if I get the correct connection or anything else?
b)
How can I get in the main.cpp an event (OnShowMessageDlg) or any message from the server? Do I need to add something to the sink class?
c)
Must I add something in the Sink class to get the an event in the invoke function? Or how should this work?
Let me know If you need any more information.
Once more, thanks for any help.

Yes, you need to add code into the Invoke methods that looks at the dispid that's passed and maps that to the method you need to call. In addition, you need to unpack the parameter values from the struct pointed at by pDispParams.
Also, that thread needs to be in a window message dispatch loop - my understanding is that COM method calls are passed from other threads and processes into your thread using windows messages.
I know you can't/don't want to use ATL and I can totally understand that...but ATL does make this sort of thing REALLY easy

Hi Stuart,
thanks a lot for your reply. Do you know if there will be an example about the invoke theme? I didn't know how this function will/must be called and how my functions then will be called / how I can get a message from the COM server above this invoke functions.
I know and I heared also from other people that it will be easier to work with ATL. But in this project I can't use ATL.

OK - the Invoke method is called when an event is raised by the server. It will tell you which method it's calling using the dispidMember parameter. The parameters to the call will be in the structure pointed at by pdispparams. You can pass back a result in pvarResult.
So, you could implement your Invoke using a switch statement and parameter transformation like this:
STDMETHODIMP CSink::Invoke(DISPID dispIdMember, REFIID riid, LCID lcid,
WORD wFlags, DISPPARAMS* pDispParams,
VARIANT* pVarResult, EXCEPINFO* pExcepInfo,
UINT* puArgErr)
{
if ((riid != IID_NULL))
return E_INVALIDARG;
HRESULT hr = S_OK;
switch (dispIdMember)
{
case 1:
if (pDispParams->cArgs != 1) return E_INVALIDARG;
if (V_VT(&pDispParams->rgvarg[0]) != VT_BOOL|VT_BYREF) return E_INVALIDARG;
OnConfigurationApply(V_BOOLREF(&pDispParams->rgvarg[0]));
break;
case 2:
break;
}
return hr;
}
HTH!

The problem I have before is that the Invoke Function will not be called. What must I do that this function will be called from the Server when an event is raised?
I can see that an event is raised from the server because an dialog will be opended. But the invoke function will not be called.
