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. ActiveX Control in an Composite Control 22-Jul-01 6:00 22-Jul-01 6:00  Environment: Windows 2000, VC++ 6.0 Hello, I wrote an ActiveX control: MyCtrl. I wrote a composite control that uses MyCtrl. 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. HRESULT GetDlgControl( int nID, IUnknown** ppUnkCtrl ); Extending SIP 21-Jul-01 10:47 21-Jul-01 10:47  Hello, How would it be possible to "extend" any SIP of any appplication ? I mean I would like to insert a processing that would modify/verify each user input from any kind of SIP, of any application, before the input string is sent to the application currently owning the SIP. Do I have to write a DLL, how could it work ? I plan this of course under Windows CE. Do one need something related to hooking (I know that is very restricted under Windows CE) ? Thank's in advance. --Francois COM in kernel mode? M Bandu19-Jul-01 9:28 M Bandu 19-Jul-01 9:28  Hi, Can I call COM object from device driver (from kernel mode)? I would like to do is to load up COM, so I can hook it up later. Thanks BD REPORT GENERATION USING MFC 18-Jul-01 23:35 18-Jul-01 23:35  I am preparing a dialog based application in VC++(MFC).In that I want to prepare a report based on some sql query.I am trying to use "msdbrptr.dll" and "msdbrpt.dll" and "msde.dll". Now when I try this code _DataReportPtr pDr(__uuidof(_DataReport)) It throws an exception "class not registered" .Send me the sample code explaining how to print a report(data report)using mfc. if there is any other way to prepare a report (with print option) then please let me know. I don't want to use crystal reports. Returning Records From DCOM AJ12318-Jul-01 4:13 AJ123 18-Jul-01 4:13  Hi, I am adding function to DCOM Clients and Servers. 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. Tips or links to articles/examples would be greate. thanks Open an ADE file with CDataSource Robbie Grundel17-Jul-01 15:40 Robbie Grundel 17-Jul-01 15:40  Can i open an ADE file with CDataSource to check it's status. Have tried various provider strings etc. any ideas Robbie G Where is cabarc.exe on VC++ 6.0 (Pro Edition) Gary Barwick17-Jul-01 13:19 Gary Barwick 17-Jul-01 13:19  I have built an activex control that I need to sign and package for network (&internet) delivery. MSDN make references to cabarc.exe and a Cabinet SDK as beening the only way to make cabinet files yet does not provide them on VC++6.0 only on VC++ 5.0 CD set. Is there a new way to make cab files that MSDN eludes to tell me about? Where on Microsoft site can I download cabarc.exe? I am lost! Many Thanks Gary, Re: Where is cabarc.exe on VC++ 6.0 (Pro Edition) Michael Dunn17-Jul-01 14:21 Michael Dunn 17-Jul-01 14:21  The CAB SDK used to be at http://msdn.microsoft.com/workshop/management/cab/cabdl.asp but alas in the Great MSDN Reorganization of 2001(tm) that link doesn't work anymore. --Mike-- http://home.inreach.com/mdunn/ Sometimes, arming yourself with a big pointy stake just won't do you any good. Re: Where is cabarc.exe on VC++ 6.0 (Pro Edition) Gary Barwick17-Jul-01 15:08 Gary Barwick 17-Jul-01 15:08  Thanks Mike, I spent a few hours yesterday chasing my tail on the MSDN site. A fellow developer suggested searching www.download.com (cnet site). There were a few CAB utilities there that seemed to do the trick so I am out of deep water for now! (Freeware/Shareware once again does the trick... many thanks to all producers of such software) Gary. drag and drop an url Am400017-Jul-01 8:28 Am4000 17-Jul-01 8:28  hi anybody has any code to drag and drop a url/link from a IE control. the code would be in c++ and com api. thanks.

The VC 6.0 compiler says the proxy requires at least NT 4 to run. This server should run on 9x, NT 4/5
