Hello i have a problem with event sink. I need to contol a NewWindow when it pops-up (to change if its visible toolbar)
i'm not sure about pDispParams->rgvarg[1].pdispVal; parametr. SOmehow i dont have handle to the new window.
Please help...
Code for NEWWINDOW2 event:
HRESULT __stdcall DWebBrowserEventsImpl::Invoke(DISPID dispIdMember,
REFIID riid,
LCID lcid,
WORD wFlags,
DISPPARAMS __RPC_FAR *pDispParams,
VARIANT __RPC_FAR *pVarResult,
EXCEPINFO __RPC_FAR *pExcepInfo,
UINT __RPC_FAR *puArgErr)
{
if (dispIdMember == DISPID_NEWWINDOW2)
{
//event sink is working because i can get a test message every time a new window pops
//but somehow i cant control a new wondow ?
MessageBox(NULL,"TEST","TEST",NULL);
//////////////////////////////////////////////////////////// this part wont work ?
CComQIPtr< IWebBrowser2> Nwin= pDispParams->rgvarg[1].pdispVal;
Nwin->put_Visible(TRUE);
Nwin->put_MenuBar(TRUE);
Nwin->put_ToolBar(FALSE);
}
return NOERROR;
}

MSDN says about DISPID_NEWWINDOW2:
The user clicks a link while pressing the SHIFT key.
The user right-clicks a link and selects Open In New Window.
The user selects New Window from the File menu.
There is a targeted navigation to a frame name that does not yet exist.
I hope it is not one of above case.
Can you show coclass declaration for this class?

I have a simple VB6 class in a DLL that has two functions , AllocateLargeArray and DeAllocateLargeArray. I am driving the DLL from an MFC App and in this App I have a button that creates an interface to the VB Class and calls the two functions then releases.
If I then look at the Apps Private bytes (VM Size in TM) of the process the value seems to initially increase lots say to 1900k then on subsequent presses of the button drop to 1600k again to 1300k again to 1000k and then shoot back up to 1900k !
Can anyone tell me why is behaviour ?
To aid here is a a snippet of the code in VB.
Thanks.
Option Explicit
Dim mCollection As Collection
Public Function AllocateLargeArray()
Dim loc As MyStruct
Dim ii As Integer
Set mCollection = Nothing
Set mCollection = New Collection
For ii = 1 To 10000
Set loc = New MyStruct
mCollection.Add loc
Next ii
End Function
Public Function DeAllocateLargeArray()
Dim ii As Integer
ii = 1
Do While ii <= mCollection.Count
mCollection.Remove ii
Loop
Set mCollection = Nothing
End Function

I'm no expert in VB, but, while removing loc(MyStruct) from mCollection, shouldn't you set element to be removed to nothing.
i.e.
Do While ii <= mCollection.Count
mCollection.Remove ii
Loop

If it was not deleted surely next time I called the same function the memory would just keep increasing and increasing no ?
I followed what you said and set ever Item to Nothing before removing it from the Collection, but I still get strange memory readings like before though a little different !

Hmmm, I can see that much memory leak, mentioned earlier.
Dont know how you are using it.

hi
I am working killing a process using WMI iam using the following code .
HRESULT hres;
BSTR ClassName = SysAllocString(L"Win32_Process");
/* YOU NEED TO CHANGE THE NUMBER VALUE OF THE HANDLE
(PROCESS ID) TO THE CORRECT VALUE OF THE PROCESS YOU
ARE TRYING TO TERMINATE (this provides a path to
the class instance you are tying to terminate). */
BSTR ClassNameInstance = SysAllocString(
L"Win32_Process.Handle=\"\1418\"");
_bstr_t MethodName = (L"Terminate");
BSTR ParameterName = SysAllocString(L"Reason");
IWbemClassObject* pClass = NULL;
hres = m_pIWbemService->GetObject(ClassName, 0, NULL, &pClass, NULL);
IWbemClassObject* pInParamsDefinition = NULL;
IWbemClassObject* pOutMethod = NULL;
hres = pClass->GetMethod(MethodName, 0,
&pInParamsDefinition, &pOutMethod);
if (FAILED(hres))
{
cout << "Could not get the method. Error code = 0x"
<< hex << hres << endl;
}
IWbemClassObject* pClassInstance = NULL;
hres = pInParamsDefinition->SpawnInstance(0, &pClassInstance);
// Create the values for the in parameters
VARIANT pcVal;
VariantInit(&pcVal);
V_VT(&pcVal) = VT_I4;
// Store the value for the in parameters
hres = pClassInstance->Put(L"Reason", 0,
&pcVal, 0);
// Execute Method
hres = m_pIWbemService->ExecMethod(ClassNameInstance, MethodName, 0,
NULL, pClassInstance, NULL, NULL);
if (FAILED(hres))
{
cout << "Could not execute method. Error code = 0x"
<< hex << hres << endl;
VariantClear(&pcVal);
SysFreeString(ClassName);
SysFreeString(MethodName);
pClass->Release();
pInParamsDefinition->Release();
m_pIWbemService->Release();
//pLoc->Release();
CoUninitialize();
return 1; // Program has failed.
}
it is working fine ,but here iam gicing the Process ID which has to be terminated like 1418.
Instead of ProcessID i want to use process Name like CAlc.exe or notepad.exe
but when IAm tring to change the code with the process name like
SysAllocString(
L"Win32_Process.Name=\"\notepad.exe\"");
notepad is not terminating . can you please help me to solve it.
Thanks in Advance

pItem1Ptr->put_innerHTML(L"");
The code above is to change something in the HTML.
It works well in IE6,I can get the gif picture successfully.
But when I run my code in IE7, this code can't work........and I found that, if I replace c:\\float.gif into http://somesite/somepic.gif It can work nice. So I think there maybe something changed in IE7, can anyone tell me how to show my c:\\float.gif picture in IE7????

Try using "file:///c:/float.gif" (as you should if file paths are used).

well,thanks for your reply.
but both your method or mine get the same result.
I use get_innnerHTML ,and print the result:
It seems just ok.
But whatever,I can't see the picture.
The propertis of picture I just can see:
Protocol: Not Available
Type: Not Available
Address: Not Available
Size: Not Available

Hi All,
Recently I got some doubts regarding Connection Points. Please replay the mail, if you know the answers.
1. What are the main drabacks (except implementation difficulties). Suppose client requested the server for some operation and doing its wone work. In the time of server doing work, if some problem occurred on the server. Then how server inform the client saying that operation failed.
My doubt is how server inform client sink, when server fails to do the operation.
2. Why Microsft intraduced delegates, while we are having Connection points. I know delegates are type safe, object oriented. But why elemenated Connection points.
3. VB internally uses Sink Map, IConnectionSimpleImple or not.
Thanks

Have a debug failure when creating a window of my COM 3d imager. I think its an issue with passing my OLE control through my sub classes.
When I created my 3d imager window inside my application…
bRet = m_pSatMap->Create("Internal_DB_SAT_Map", 0, Rect, pMainFrm, ID_SAT_MEM_MAP, NULL, FALSE);
I got an assertion error from ENSURE(afxOccMgr != NULL)”. After researching this I found that this would occur when AfxEnableControlContainer() was not call. However it is in my main but not in my subclass where the Create is called. So I added it to that class, and now I have another assertion problem. Now “ASSERT(pWndCtrl->m_pCtrlSite == NULL)” is failing.
I think I’m looking for a site that speaks to how to pass afx control to classes inside an application.
Thanks for any help

Hi Community,
for my next project, I need a kind of data grid in my application. Is there a handy ActiveX-control which I can use on a FormView, or is there a way to use the Windows Forms DataGridView in my MFC-App?
Thanks,
Frank.

Hi everybody,
I've got a strange thing using my DCOM application(s).
I wrote both server and client, and one of the last issues I can't resolve is the following:
On the server machine (EXE Server with MFC) I have the following class method (with implementation):
STDMETHODIMP CAugVisionEngine::ReadText(BSTR CharSetName, int pTop, int pLeft, int pHeight, int pWidth, BSTR *OcrString)<br />
{<br />
AFX_MANAGE_STATE(AfxGetStaticModuleState())<br />
...[code omitted here for brevity]
...
char* strTemp = (char*) malloc(sizeof(OcrReport_tmp->readString)+1);<br />
strcpy(strTemp, OcrReport_tmp->readString); <br />
*OcrString = W2BSTR(A2W(strTemp));<br />
<br />
return S_OK;<br />
}
where the last parameter, the BSTR, is the return value of the function (just [out], not [out, retval])
When I call the function from the client (for now MFC application, just to test, but the release will be a console application), in a way like this:
BSTR OCRBSTR;<br />
<br />
pIVE->ReadText ("C:\\Patterns\\3260\\05042800\\1235.abc",40, 249, 48, 83, &OCRBSTR);
I get that the server constructs the BSTR correctly (at least, it seems to do it, since a logfile is populated correctly), but my client retrieves nothing...
I'm stuck...
Any ideas?
Thanks in advance,
Morenz.

your code doesn't seem to have problem.
morenz wrote: *OcrString = W2BSTR(A2W(strTemp));
As you said, this value you are writing in log file, isn't it?

|

yes, I'm writing it in a file as a string. When I debug it, I see that the BSTR has the correct value, too...
For now I workarounded it, making the client open the file directly on the server and getting the string itself, but it's not elegant...

Hello,
I can't figure out how to derive a class from an interface with pure functions side by side a class that implements those functions and use those functions in place of the pure ones. That is:
interface BaseInterface : public IUnknown
{
};
interface DerivedInterface : public BaseInterface
{
STDMETHOD_( INT, AddNumbers )( INT LHS, INT RHS ) PURE;
};
class BaseInterfaceImpl : public BaseInterface
{
STDMETHOD_( ULONG, AddRef )()
{
return S_OK;
}
STDMETHOD_( ULONG, Release )()
{
return S_OK;
}
STDMETHOD( QueryInterface )( REFIID RefIID, LPVOID *ppObject )
{
return S_OK;
}
};
class DerivedInterfaceImpl : public DerivedInterface, public BaseInterfaceImpl
{
public:
STDMETHOD_( INT, AddNumbers )( INT LHS, INT RHS )
{
return LHS + RHS;
}
};
MSVC gives me the error:
c:\documents and settings\todd\my documents\visual studio
2005\projects\whitehall\toying with c++\toying.cpp(72) : error C2259:
'DerivedInterfaceImpl' : cannot instantiate abstract class
due to following members:
'HRESULT IUnknown::QueryInterface(const IID &,void **)' : is
abstract
d:\program files\microsoft visual studio
8\vc\platformsdk\include\unknwn.h(113) : see declaration of
'IUnknown::QueryInterface'
'ULONG IUnknown::AddRef(void)' : is abstract
d:\program files\microsoft visual studio
8\vc\platformsdk\include\unknwn.h(117) : see declaration of

'ULONG IUnknown::Release(void)' : is abstract
d:\program files\microsoft visual studio
8\vc\platformsdk\include\unknwn.h(119) : see declaration of
'IUnknown::Release'
I've got the source code of my dummy-test scenario at
http://lanlocked.net/junk/toying.cpp. I managed to get it to work by
deriving DerivedInterface from BaseInterfaceImpl but I don't see this
as a solution, rather a workaround (I'd like to keep the interfaces
"clean" and 100% pure). If it's impossible to do what I'm trying to do,
what are the other methods of inheriting in COM?
Thanks in advance,
Todd

Can you explain this ?

It is because, compiler doesn't find definition of this function. Dont combine it with one in BaseInterfaceImpl.

Dear All,
I am new to this COM usage in VB6. I created a COM object and it was given me a dll file and also installed to the computer so I can get the dll in References in VB6.
