Hi folks,
I've built an ActiveX control successfully, can view it in OleView, it's working fine.
I'd like to embed it in an HTML web page. Obviously, users that don't have this installed will need to run my MSI installer program that registers the ActiveX control, writes some things to the registry, etc. How do I tell the web page to use my MSI installer if the user doesn't have the ActiveX control already installed?

I have a dll written in C++ running in a Linux machine. Now i want to move that dll to a Windows system and use it with a Windows application.
How can i do that?
Can you please tell what all are the performance issues i face?
What all are the dependencies?
Thanks in advance

- The source code needs to be made compatible across the platforms and compilers used on Linux and Windows (Boost & STL are usefull in this case and versions of it are available for Win/Linux compiler environments)
- Platform specific APIs need to be conditionally compiled (to retain the same code base across environments) or replaced
- On Windows you'll need to write some DLL module code (DllMain mostly) and expose your codes functions as DLL exports (decorate a function with __declspec(export) or use the .DEF file method)
- Compile the code and link as a DLL (library)

A COM server accepts typed data. So, in principle you have to do some workaround to obtain generality.

I am using following code
COSERVERINFO serverinfo;<br />
COSERVERINFO* pServerInfo = new COSERVERINFO;;<br />
COAUTHINFO* pCOMAuthInfo = new COAUTHINFO;<br />
<br />
serverinfo.dwReserved1 = 0;<br />
serverinfo.dwReserved2 = 0;<br />
serverinfo.pwszName = m_strServerAddress.AllocSysString();<br />
pCOMAuthInfo->dwAuthnLevel = RPC_C_AUTHN_LEVEL_NONE;<br />
serverinfo.pAuthInfo= pCOMAuthInfo;<br />
<br />
if (m_strServerAddress.IsEmpty())<br />
pServerInfo = NULL;<br />
else<br />
pServerInfo = &serverinfo;<br />
<br />
MULTI_QI qi = {&IID_ICRSObj, NULL, 0};<br />
<br />
hr = CoCreateInstanceEx(CLSID_CCRSObj,NULL, CLSCTX_ALL, <br />
pServerInfo, 1, &qi);
but when i call CoCreateInstanceEx i get the error : hr 0x800703e6 Invalid access to memory location.

Hi all!
I want to pass the object(say studentobj having members:id,name,sub1mark,sub2mark)from VB client to the method of interface.
requirements:
1) I want that the passed object's should be stored in COM servers student class (a class added in the com server) other than the interface class.
2) COM Server is having a method in interface that returns the student object that has got the 1st rank among the other student.
All I want to know is only how to pass and return objects to and from COM Servers.
Thanks in Advance.

Hi I created an ASP.NET application in VS 2005, IIS 5.1 (which would login to a site like gmail.com after taking the user & password details), using vb.I am using interop.shdocvw.dll to invoke the internet explorer through which i am navigating the elements of the html document and passing the values(User Name And Password). When I run this URL in the windows 2003 server machine (local host where application is installed) it works fine ,but when i am trying to access the same url from other client machines ,it is promting me to enter username & password for the windows 2003 server.
How do I bypass the user / password validation for windows 2003.

I have one Coclass named CXNode which is implementing methods of interface IXNode. I want IXElement to be derived from IXNode as I want methods of IXNode. In IXElement I have two extra methods GetAttribute and SetAttribute. I don't want to rewrite methods which are already written in CXNode.
Thanks in advance!!!

Hence derive from CXNode.

But in COM you can't derive a coclass from another coclass.
|
|
|
|

You don't need that. You have just to derive the implementation from the C++ class (or make the CoClasses both inherit from the same C++ class, Oh yes, multiple inheritance, ATL docet).
