Hey Im not a real advanced programer or anything, but when I use Turbo C++ in class, I can include <stdio.h> and freely use gotoxy(int,int); thoughout the program to move the cursor to a certain spot on the screen and print something there. What the hell is up with visual c++. It's telling me that gotoxy(int,int); is an "undeclared identifier". Well Im lost... OMG | :OMG:

I'm looking for a (speedy) class/algorithm to convert Paradox/Excel date serials to a day-month-year value and back.

The Paradox/Excel serial date is the number of days since 1-1-1900. I was wondering if anyone knew a fast algorithm to convert a serial date to day-month year and vise versa...

change the tab font of a property sheet from the same tab.

Hello,

I need to change the font of a property sheet tab from the same tab.

Let's say that in that tab there is the control of alarms and emergencies that can happen in a machine that I control. when a new alarm or emergency happens I want to be able to change the color of the "alarms and emergencies" tab.

As always thank you in advance.

NOTE:
I want only to change the font of the "alarms and emergencies" tab, the other ones should keep the same font than before.

AFAIK, tab controls don't support multiple fonts. You can try to use TCS_OWNERDRAWFIXED style. Check this article for sample program which simulates disabled tabs using owner-draw:

This must be a new feature since I've never seen it. Maybe you'll need to use MFC7?

Which version of CRichEditCtrl do you use (or want to use) ?? If you don't want to use version 1.0, than you have to use

m_hInstance = ::LoadLibrary("RichEd20.dll");

instead of

AfxInitRichEdit();

BTW: I havn't seen this feature before.... Confused | :confused:

Hope this helps a little...

I have a initialized a bitmap with a bitmap info header,which i have mentioned of bitcount=1(monochrome bitmap).I want to get the bits of the bitmap.Is it possible to get the bits by using function called GetDIBits for a monochrome bitmap.

Is there any reason you can't create it as a DIBSECTION ? Then you'll have a pointer to the bits by default.

GSM Programming Woes

I have created an image transfer system using the UK GSM network. When the send and receive ends are both on my desk (both modems in the same GSM cell), then I have no problems at all, the system and the software work perfectly.

However, as soon as the ends are separated by any reasonable distance (in to a new GSM cell) the system falls over. Having done some extensive ~~playing around~~testing I have managed to discover that the modems response to dialing any out of cell number is 'NO CARRIER'. Unfortunately I have very little comm.s experience and even less experience with GSM comm.s.

I can write the most clever code in the world, but if I can't get a call to connect it's a waste. Does anyone have any ideas as to what's occurring here?

Copy & Paste in CView derived classes

How do I do it? :-P

I want to enable copying from a CScrollView derived class the selected data in text format. The clipboard stuff I can do, but what is bugging me is whether I really have to code the selection stuff myself.

Yes, you'll have to do that yourself. What kind of information are you displaying in CYourView?

You may consider switching to CEditView or CRichEditView then.

Still using old 16bit DOS apps? Puh! Sleepy | :zzz:

However, a 16bit app is started as any other app either using ShellExecute(Ex)() or CreateProcess() APIs.

the standard window buttons can't be changed in color... however they can be owner-drawn... check some articles on this site ... Controls - Buttons for example, is a section which contains lots of good info on this subject

Reading unicode strings from a file..

How can i read the unicode string from a file line by line?

Thanks

Re: Reading unicode strings from a file..

Roman Nurik1-Aug-02 21:25

first you check the first two bytes of the file... if they are 0xFF and 0xFE, respectively, the file is little endian unicode... meaning that every character in the string is two bytes and that the value (up to 65535) is a little endian "short"... if the first two bytes are 0xFE and 0xFF then the file is big endian unicode, meaning that each character is a big endian "short" value... if the first two bytes are anything else, it's not unicode

NOTE: i'm not sure about UTF-8, i never figured out the byte pattern for that format
