Re: Monitoring incoming calls 16-Mar-01 7:14 16-Mar-01 7:14  There are plenty of examples in the platform SDK. I did some TAPI work about 3 or 4 years ago. We had an idea for an internet/TAPI product, but it didn't get past the prototype stages. That was using TAPI 2.0, which I don't remember much of. TAPI is up at V3.0 I think so, you'd best look at the docs. I think for callerID you may need a specialist card unless modems can do that now (couldn't when I last tried, but like I said, that was a while ago).

Depending on the environment you must live in, telphony testing can be a pain. I use SAX Comm Objects and it works well for both outbound and inbound calls. I don't think Caller ID is part of Sax Comm. Paul Burton Outgoing calls 28-Apr-01 2:57 28-Apr-01 2:57  How to pass messages over the telephone?

Srinivas How can I prevent the MFC framework from enabling my toolbar buttons? 16-Mar-01 6:44 16-Mar-01 6:44  Hi I've tried to create toolbars with disabled buttons. Doesn't work. I've thrown in a check and discovered that someone enables the button right after my call to CToolBarCtrl::EnableButton. How can I prevent this? I'm quite sure that's the problem because I have hot toolbars working without problems. Is there anything different with using hot toolbars compared to disabled buttons? Re: How can I prevent the MFC framework from enabling my toolbar buttons? Chris Losinger16-Mar-01 7:06 Chris Losinger 16-Mar-01 7:06  you have to use the UPDATE_COMMAND_UI handlers to disable toolbar buttons. like this: void CSAFileMonDoc::OnUpdateWatchStart(CCmdUI* pCmdUI) { pCmdUI->Enable(!m_bRunning); } -c ------------------------------ Smaller Animals Software, Inc. http://www.smalleranimals.com URGENT...winsock oneillci16-Mar-01 6:36 oneillci 16-Mar-01 6:36  I'm new to DirectX programming and I'm doing a breakout clone as a college project. I have to add some network functionality to my game though. I think I've got my server up and running. I've created my socket, bound it and called WSAAsyncSelect with my own eventID and started listening. I just want to connect my client and send simple messages of 2 integers(that's all I need). I just need some help connecting to local host to send messages. On the client I've created my socket, bound it and called WSAAsyncSelect with my own eventID and I'm trying to connect and it is failing here. Can someone please help?

It turns out that the problem existed in my Frame Window's WndProc. You have to return '0' when you handle the frame's WM_SIZE message. Go figure.

Bogdan Registry access from Console App Robert Bushlow16-Mar-01 5:45 Robert Bushlow 16-Mar-01 5:45  I have an existing console app in which I need to get some information from the registry which is placed there by a regular Windows based MFC app. I have tried WriteProfileString(), WriteProfileInt(), GetProfileString(), GetProfileInt(), etc. with no luck. Any suggestions? Thank You. Re: Registry access from Console App Steve Driessens16-Mar-01 16:51 Steve Driessens 16-Mar-01 16:51  G'day Robert, Do you know the full path of the registry key you want to access? If so, you can use the RegOpenKeyEx, RegQueryValueEx, RegCloseKey and other related functions. Hope this helps.

Stephen Printing Problem - WinNT/98 - VC6 Nathan Walker16-Mar-01 5:43 Nathan Walker 16-Mar-01 5:43  I've had some freaky stuff going on with printing for a while. I'm hoping someone can help me out here. I've got a bitmap (technically, I'm trying to write the whole screen) that I'm trying to write out to a network printer. The code I'm working with does the following: Creates a screen-compatible memory DC, then blits the screen into it. Converts that into a DIB, then calls StretchDibBits to the printer DC. Works perfectly, under NT. When I try to run the same code under Win98, I have problems. The blit works fine, but the stretch on the DIB returns an error. The return code indicates I have an "invalid parameter". If I stretch first and then SetDiBits, the code works, but I lose all my color information... I'm completely confused. I've tried everthing I can think of to get this code running. For the moment, I've just put in a check and a message box that indicates this feature is only available under WinNT, but I'd like to fix it if at all possible. Anyone have any ideas? >>>>>>>>>> Nathan If a picture is worth a thousand words, reproducing a bug is worth ten thousand. resize activx into a dialog bogdan16-Mar-01 5:34 bogdan 16-Mar-01 5:34  I have a class for resize my dialog.

Ciaran Still use MFC in new projects? Christian Reichenbach16-Mar-01 1:24 Christian Reichenbach 16-Mar-01 1:24  Hi, I'm planning to realize a new project with Visual C++. It should uses ADO and other COM components. Is it clever to still use MFC with lots of conversions and other disadvantages or should I use a new technology like ATL or WTL? What's your opinion? Thanks in adance Christian Re: Still use MFC in new projects? 16-Mar-01 1:42 16-Mar-01 1:42  I found MFC a lot easier to use and works every well for all of my projects. The latest ATL may be a little better, but we do not have the luxury of upgrading to the latest version of VC++. We are still using VC++ 5.0. ATL in VC++ 5.0 is a pain in the butt for simple things such as adding an event to your com object. A lot of people here will probably tell you different things, though. COM+ & MFC Question Gerry15-Mar-01 22:28 Gerry 15-Mar-01 22:28  1. I'm looking for guidelines for creating a COM+ application using VC++ 5.0. I have knowledge of idl, ATL, VC, & COM. Not sure on how to build this knowledge into a COM+ Application in Windows2000. Is there any good documentation available. 2. Is MFC Dead, is it still supported? Gerry.
