I need to grab the text from the browser that is selected by the user through mouse & keyboard action, and display this dynamically in the plugin's treeview. how do I do this? My idea is to hook up to DHTML events, but I'm not sure. how do I get the selected text from IE + determine what part of HTML/DHTML element it is? TIA, I'm an alien, I'm an alien it's a beautiful life.... Bush Re: dynamically displaying content in IE Plugin Erik Thompson24-Jul-01 7:24 Erik Thompson 24-Jul-01 7:24  Amit, I and another person (can't remember who) have already created explorer bars that are treeview explorers of the current html page being displayed. Mine sits on the left and the other guy's sits on the bottom of the IE window. I haven't released it but I can send you a copy of the plugin if you're interested. Cheers, -Erik ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ My thoughts are my own and reflect on no other. Instantiate a COM DLL remotely? Matt Philmon23-Jul-01 18:13 Matt Philmon 23-Jul-01 18:13  Sorry, first time for this and I'm not sure which direction I need to take... I have an ATL COM DLL that wrappers parts of another COM component written in Java provided by another vendor. It works great running on the same server as the Java component. However, the intent is to have the ATL component connect remotely to the Java component. I don't really care how the problem is solved... instantiating the ATL object on the server (Web server) from the client (how?) or having the ATL component which is currently downloaded to the client remotely instantiate the Java component (how?). The only direction I know to look is DCOM but that's not the direction I wanted to go. For one thing, with DCOM I'd have to setup (from a web browser) the Java component on the client so I can select it using dcomcnf to go to the server to run instead (that's the only way I could select the option that I saw). Could anyone point me in the right direction? I'm a little lost... Thanks, Matt Re: Instantiate a COM DLL remotely? Jesse Rosalia16-Aug-01 19:47 Jesse Rosalia 16-Aug-01 19:47  Actually, I think DCOM is the way you want to go. You can programmatically set everything DCOMCNFG does (look into CoCreateInstanceEx for specifying server, and the AppId registry keys and LSA functions for security settings if they apply). Might I suggest, if you are going to use multiple clients off this server, that you turn your COM dll into an exe. COM dlls require a surrogate (very thin wrapper that does nothing really but provide an executable layer) to run on a remote machine, because frankly they themselves arnt enough to sustain an independant process. DCOM provides a default surrogate, DllHost.exe, which isnt bad, but if your goal is to service multiple clients off that remote server, my suggestion would be to turn your DLL into an EXE. One thing I dont understand is who is the client? If its a web browser, all your objects will be "running" on the server, so you dont need to make your client aware of the objects. If its an application, then there isnt really any issue in just registering the needed classes on that client computer, is there? Hope this helps. -Jesse IDispatch 23-Jul-01 15:12 23-Jul-01 15:12  How to start several Excel books at the same time with IDIspatch? I know how to start only one Excel book using C.

Active X Control - Redrawing Jared Allen23-Jul-01 3:32 Jared Allen 23-Jul-01 3:32  I'm having some trouble with screen flickering when the browser window (or active X test control container) is scrolled. It is really quiet bad, Is ther any way to get better redrawing? with less flickering? I've tried some double buffering but it doesn't seem to work. Especially with the CDC that the OnDraw function gives me. It is an MFC base Active X control. Any ideas, would be great thanks, JAred. Re: Active X Control - Redrawing 23-Jul-01 8:21 23-Jul-01 8:21  It is probably EraseBackground that causing this excessive flicker. Try to intercept WM_ERASEBKGND and return 1. Worked for me. Re: Active X Control - Redrawing 23-Jul-01 21:18 23-Jul-01 21:18  If you BitBlt a bitmap to the background through the WM_ERASEBKGND and the bitmap is bigger than the dialog it will flicker. Make sure the bitmap is exactly the size of your rect or smaller.

How do I call functions of MyCtrl? I can get the CWindow of that control but I need the CMyCtrl object !!! For regular controls I found the "atlcontrols.h" file in the MSDN, but I don't know how to call functions of a new control I wrote like: m_myCtrl.SetBitmaps(IDB_HELLO); Any help will be appreciated.

Re: ActiveX control in an Composite Control Not Active22-Jul-01 10:18 Not Active 22-Jul-01 10:18  Your control is CONTAINED by the composite control. You need to expose the interfaces on your controls through the composite control, or have a method on the composite control that returns an interface to your control. Re: ActiveX control in an Composite Control 22-Jul-01 21:37 22-Jul-01 21:37  Hello, I don't need a client to use the inner control. Only the composite control uses the ActiveX control. I've dragged the control on to the composite dialog and now I want in the code of the composite dialog to call functions of the control. How do I do that? Thank you, Penina. Re: ActiveX control in an Composite Control 23-Jul-01 8:50 23-Jul-01 8:50  Try GetDlgControl to get IUnknown for control your are interested in. It should be easy once you have IUnknown. As an alernative you can use custom windows messages to comunicate with hosted control.

Ammending previously written code, so i have little knowledge of the technical details of DCOM. What I wish to do is return a series of records, 3 strings to be precise. I was thinking of having one function to return a block of Record Keys. And then having one function to get individual records. Is there are any better ways of doing this? Cheers Rich IDL file and special structs 18-Jul-01 4:01 18-Jul-01 4:01  Hi, I have an ATL interface (IOLEDBConnectionPool) for which I want to expose a function (Initialize) with a DBPROPSET (an OLEDB propertyset struct) but the MIDL compiler doesn't recognize the DBPROPSET. If I use another variable-type and compile and then change the corresponding .c and .h files afterwards it works just fine but it is not a nice solution so what can I do to make the .IDL file compile (see extract from .IDL-file below)? import "oaidl.idl"; import "ocidl.idl"; [ object, uuid(D5602000-F5DA-45A0-9A14-066B0D23AAE1), helpstring("IOLEDBConnectionPool Interface"), pointer_default(unique) ] interface IOLEDBConnectionPool : IUnknown { [helpstring("method Initialize")] HRESULT Initialize([in] DBPROPSET *pPropSet); }; .... Johannes Re: IDL file and special structs Not Active20-Jul-01 2:57 Not Active 20-Jul-01 2:57  There are two ways you can get around this. One, add the definition of the DBPROPSET struct to your IDL so it know what you mean. This will work if the clients are C++, VB, VBScript and the like won't. Two, since the param you are passing is a pointer just use a LONG and convert in into a DBPROPSET* when you get it. This would be the prefered method. Passing data 17-Jul-01 20:40 17-Jul-01 20:40  Hi I need to pass many variables from a client written in VB to a COM server written in VC++. My idea is to modify them by reference in the server. Is there any way to send a structure or a class, containing my variables? The types are int string and bool.
