Function parameter Sly66699918-Sep-04 6:35 Sly666999 18-Sep-04 6:35  I am trying to code a (Visual Studio)C# test program in order to control an ActiveX component. The connection between the component and my test program is done. The component exposes methods that use a parameter System.object. I don't know how I should make such a parameter. In the activeX component (coded in C++), this parameter is described as a pointer to a DISPATCH object (a IDataContainer type). As I'm quite new to COM and ActiveX, and I haven't found any information about how to make this function call? thanks in advance, See you, SlY Re: Function parameter darkbyte20-Sep-04 6:31 darkbyte 20-Sep-04 6:31  Hope you know how to handle variants, First, use a VARIANT as input parameter, Then, check that input field type is Dispatch type Next, QueryInterface the dispatch member of the variant field Sorry, no time for sample, im at work. Download Progress Callback (activeX) AssemblySoft17-Sep-04 3:46 AssemblySoft 17-Sep-04 3:46  Can someone point me in the right direction for creating download progress information while an activeX control is installing. presume it's some kind of callback but would appreciate some help. I've used similar Callbacks for standalone apps, but not sure how the connections is made as i want information about myself as i'm downloading. hmmm - Confused! thanks in advance Carl ATL Control SafeForScripting / Initialisation AssemblySoft16-Sep-04 23:01 AssemblySoft 16-Sep-04 23:01  Hi, I've created an ATL control with a full control (activeX) added to it. It is downloading and registering properly, but Internet Explorer says the control is NOT marked safe for scripting. I've doen this with an MFC based control but don't know what to do for my ATL version.

At this time I’m only using the ActiveX technology to publish my MFC application on the net. I’m about to make a call to may webpage like this: http://www.mypage.com?user=bill&password=12345 How may I pass the “user” and the “password” into my ActiveX? All suggestions are helpful. _____________________________ ...and justice for all APe Re: Make a call to my ActiveX from my webpage. darkbyte17-Sep-04 15:42 darkbyte 17-Sep-04 15:42  how do you access your activex object ? is it using the < object > tag ? if so, how about you use the other tags that it can use (i cant remember the syntax) < param user='< %=Request("user")%>' > < param password='< %=Request("password")% > ' > if you instantiate your control server side: < % myActiveX = new ActiveX("MyProg.Id"); myActiveX.User = String(Request("user")); or myActiveX.SetUser(String(Request("user")), String(Request("password"))); % > my script code is in JScript since this is the flavor i prefer, but the same can be achieved using VBScript.

COM+ Transaction Problem ProffK16-Sep-04 4:21 ProffK 16-Sep-04 4:21  I have a simple test object with one method that opens an ADO connection, performs an insert, and closes the connection. When I enlist the object in a transaction I incur a delay of about 15 seconds in destroying my closed connection object, both explicit using 'set cn = nothing' and implicitly if I omit the set and the object goes out of scope.

I don't know is this the right place for this question, so my apologies if it isn't. I have project written in C#, and now my new requirenment is that I must embed IE (i think that wizard generates ActiveX control?) in one of the forms. That control loads some html which has JavaScript code with which I must comunicate. If anyone can shed some light on how to attack the problem, or point me the right way, I'll be grateful. And I promise if I get it to work I'll publish the code on CodeProject. Thnx in advance. Re: Comunicate with IE Antti Keskinen15-Sep-04 3:05 Antti Keskinen 15-Sep-04 3:05  For a C++ implementation, see this[^] article here on CodeProject. It shows you how to use the IHTMLDocument2 interface to enumerate and execute JavaScript functions coded on a HTML page. As it uses a lot of COM, it may be difficult to port this to C#. The process how to call JS functions is precisely the same, though. The required functions and variables differ, though. But reading the article will give you an idea how to execute JS functions by using COM. Next step is to implement this approach using C#. Happy coding -Antti Keskinen ---------------------------------------------- The definition of impossible is strictly dependant on what we think is possible.

In one of the threads I am creating an instance of IGlobalInterfaceTable and calling RegisterInterfaceInGlobal(..). It returns S_OK. If I unmarhsall this interface in the same thread somewhere down the line, it works properly. But when I create instance of IGlobalInterfaceTable in another thread, and call GetInterfaceFromGlobal(..), it returns me HRESULT of 0x8000FFFF which is Catastrophic failure. Can anyone help?
