Thanks for Pointing me to my Mistake.... I forget to add that you can handle Wm_CTLCOLOR message in the Derived class Itself so no need to handle that in the main Class. If He (i.e. Vikas) don't want to go for WM_CTLCOLOR solution.. AFAIK that not possible.. if possible point me to link too

Hi,
Can anybody tell why wifstream doesnt take TCHAR string asit parameter though its meant for it???
wifstream infile(wszfile); //where wszfile = L"C:\\myfile.txt"
it gives me error
"can not convert parametre 1 from 'std::wstring' to 'const cahr *' "
any solution to avoid this error ???
thanks n regards

wifstream takes WCHARs as stream inputs. The filename you pass to create the stream has to be passed as a simple string, not wstring.
You can convert your 'wszfile' to a simple string with WideCharToMultibyte() first.

TCHAR is not a multi-byte character type. it is ONLY IF UNICODE macro is defined !!!
it's defined quite that way :
#if defined(UNICODE)
#define TCHAR wchar_t
#else
#define TCHAR char
#endif
you see now that if UNICODE is not defined, your TCHAR is a simple char.
on the other hand, wifstream always waits for a wchar_t...

it seems u have defined it
TCHAR *wszfile;
wszfile=L"C:\\myfile.txt";
rather than define it as
wchar_t *wszfile;
reason has been very well explained by TOXCCT

Even if I do,
wchar_t *wszfile = L"c:\\a.txt";
wifstream infile(wszfile);
it gives me same error  I had tried it...
any suggestion?
Thanks a lot

ACtually,the other parts are all ready.The right Operation just wait the buffer filled with the welcome voice...I just want the way to do it.But thank you at all,I will check TAPI later.Thank you.

See FindFirstFile, FindNextFile, and FindClose.

In continuation with Blake V Miller
u can use
CFileFind, CFileFind::FindFile ,CFileFind::FindNextFile <br />

Hi,
I'm asked to write an application which should
1-listen on a phone line ,
2-in response to a call gives user some options and services corresponding to some digits (like: Please press 1, if you want a car! )and
3-ask him/her to press a digit if he/she wants a service
4-act on his/her option selection.
Any clue for a start , please. Where or what technology shoul I look for? TAPI? anything links?
Thank you very much.

TAPI would be good, and you also need to determine if you are supporting multiple lines, in which case you need to go higher end with a voice card like one from Dialogic http://www.intel.com/design/network/products/telecom/index.htm[^] because a modem is less reliable and only handles one call at a time.
Try to stick with TAPI, it will probably make your application more portable to different hardware and easier to write in the first place.
If you want to see a data/fax/voice application I helped write over 1o years ago, then go here and download the sample, although it works only with modems, as I recall... http://www.v3inc.com/[^]
Spend the money and time and read this book, too...

Use the TAPI protocol and that will do all for u ,
additionaly u need a card that lets u decode the
DTMF key tones during the conversation .
One of my coulige did if before 2 years using the TAPI.

Hey, thanks in advance for the help.
I am taking over a project that someone else originally designed some time ago and I haven't worked in C++ for a long time. It's a tabbed dialog application.
On one dialog there are several bitmaps (basically status lights). These each have member variables which are used to show/hide them.
I've added a new bitmap control (from the toolbar) and tied it in to one of the existing light bitmaps.
If I compile and run everything works fine. Now when I add a member variable to it through the Class Wizard, it will compile but on run it gives a debug assertion failure and crashes out.
It looks like the only additions being made to the code by Class Wizard are the member variable declaration (CStatic) and the DDX statement. Each of these are in the same places as the other declarations and DDX statements.
Yet, the debug assertion failure occurs.
Any ideas? Thanks. Jim

Which doesn't mean a whole lot until you indicate what line of what file asserted.

David thanks a lot for the quick response! I'm not at work anymore so I'll have to check tomorrow and update the thread. I thought it might be something obvious someone has come across when adding member variables. It's obviously not. I'll update tomorrow.
thanks,
Jim

Generally, if you actually go the line of code in MFC where the assert occurs, you'll see what the problem is.

Are you using threads? Are you doing any operations on the controls before the window for them was created?
