Hey everybody.
i've just programmed an activex control using c++ and mfc. now i've got the problem that it doesn't show up in my html page. the weird thing is that i can load the page from my harddisk and everything is fine. However when loading from my server the activex area just displays a white box with a little x in the upper left corner.
more weird stuff to follow:
when i open my offline document and THEN browse to my online page the activex control DOES show up correctly. O_o
I've already debugged my ocx and can say the following:
When not showing up, the module is still loaded (CMyApp::InitInstance is called) it's not unloaded prematurely (CMyApp::ExitInstance is called upon closing explorer only) CMyCtrl::OnCreate is not called... what could it be? The control was successfully VeriSign'ed by the way
Any Help is very appreciated.
Thanks in advance,
Stephan Unverwerth
UPDATE:
The problem occurs even with a blank project from the MFC ActiveX Wizard!!!

Stephan - did you ever resolve this issue? Sounds like an activation issue.

Error indicates, Linker is not able to find definition of WebLock::GetWeakReference. If it is you class, then provide one, or link the lib having information in.

I have a problem with COM ( object is Internet Explorer )
I designed a form with Internet Explorer object. Everything seem OK but when I surf a website contain inline frame ( the inline frame's location is in other domain ), I met a problem. With the main page, I can do everthing with it such as view HTML source, list links ..etc.. but with the inline frame, I can't do anything with it ! All request return message "access denied".
Thought, the error came from something about security reason of IE ( may be cross domain ? ). I can't find a way to solve this problem. I tried to set some config on IE but nothing except "access denied" message return .
Anyone can help me ? Thanks lot !
p/s : I have admin privillige to run this program.
My English's so bad, butI hope you'll understand my question !

That's the reason for the access-denied error. Allowing data to pass between different domains would lead to cross-site scripting[^] attacks.
|
|
|
|
|
Oh yeah ! I knew that but want to ask how to disable ( or bypass ) this security method.
Because I have full privillige and I know which website's safe to surf so I want to bypass this unvalue security method. Can you help me ?
I tried on Regmon to reconize which key contain enable/disable this security method but what a sad result !

Got the answer -
objCOM = Activator.CreateInstance(Type.GetTypeFromCLSID(New Guid("{4B117F12-37D1-4C19-93C8-4B318594E2A3}")))

i used builder 6 and got the whole cppbrowser to work but now i want to save the html into a text file,how do i convert the IDispatch to string?
this is what the help tells me.but honestly i don't understand
"Use Document to access an IDispatch interface for manipulating the contents of the HTML document through the COM object model. If there is no active document, Document is NULL. That is, you must first load a document using the Navigate or Navigate2 method before you can manipulate it using the Document interface.
For more information about this interface, see the document object section of Microsoft’s Dynamic HTML reference."
|
|
|
|
|
IDispatch is the standart interface, why you need it save?
The help just known you that Document inherited from IDispatch.
If you want to save html look for methods in Document that allow you to get HTMLBody as string and after that save it.
|
|
|
|
|
there where no methods for getting the string.but i got it working.
why i wanted to save the html was for the "background" history on the pc just for fun.

Hi,
I am trying to create a user in WinXP using ADSI.
I am facing problems in executing ADsGetObject.
When I try binding to LDAP using WKGUID, it gives an error.
Part of my code is:
--------------------------------------------------------
hr = ADsGetObject(TEXT("LDAP://10.175.80.24/rootDSE"),
IID_IADs,
(void**)&pRoot);
// Function written above works fine.
if (FAILED(hr)) {
wprintf(L"Bind to rootDSE failed: 0x%x\n", hr);
return hr;
}
hr = pRoot->Get(L"defaultNamingContext",&var);
wcscpy(adsPath,L"LDAP://<wkguid=");
wcscat(adspath,l"aa312825768811d1aded00c04fd8d5cd");
wcscat(adspath,l",");
wcscat(adspath,var.bstrval);
wcscat(adspath,l">");
hr = ADsGetObject(adsPath, IID_IADs, (void**) &pIADs);
// This function written just above is failing: hr is a negative value/
// pIADs comes as NULL
hr = pIADs->Get(L"distinguishedName",&var);
//At this point application crashes obviously as pIADs is NULL.
-------------------------------------------------
The 'adspath' gives the correct path as :"LDAP://<wkguid=aa312825768811d1aded00c04fd8d5cd,dc=patni,dc=com>"
I used ADsGetLastError to check the return code. But return code is success (i.e. zero)
Im unable to understand where am I going wrong.
Can anyone please help me resolving this problem?
Thanks,
Manasi
