Hi guys,
I am calling a managed dll build in 2.0 from a vb 6.0 application, the dll runs well under clr 2.0 but the vb application breaks.
I was previously using managed dll built with 1.1, and that was working fine. i have framework 1.1 and 2.0 installed with windows server 2003.
can u guys tell me what could be the problem??
Thank You.

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

Hi,
How to know how many clients are connected to the COM Component at pirticular time
Thanks
Nandu

To know no. of clients connected to your COM component, you need to create a COM+ Application.
1)->Control Panel->Admi. Tools->COM+ Applications->Computers->My COmputer->Applications->Create an empty application
2)Add your component in it, in it's components node. then
3)Export that aplication, select Application Proxy option, it will create .msi and .zip files
4)Install this .msi file on required clients.
When this component if being accessed by cleints, you can view the count of active objects of that component in
Control Panel->Admi. Tools->COM+ Applications->Computers->My COmputer->Applications->Your Aplication Name->Components
then select "detail view".
If this solves yr. problem pl. Replay me.

There is a library "COM+ 1.0 Admin Type Library" using which you can check and set state of various COM+ Application's state such like checking status and adding components to it at runtime as well as exporting application etc.
To do that you can set reference of that library in VB 6.0 IDE and check various Methods and Properties it supports.
Some of Useful Methods are
Dim loApp As New COMAdmin.COMAdminCatalog
loApp.GetComponentVersionCount(,,,)
loApp.GetMultipleComponentsInfo()
