stupid question here?
where would I start to get an editbox receiving strings one line at a time to display the last line. example
1<br />
2<br />
3<br />
4<br />
5<br />
6<br />
7
right now line 6 and 7 are out of view in the editbox, but I want the editbox to show 6 and 7, and hide 1 and 2. In other words just auto display the last messages sent to the editbox.
thanks,
JoeSox

Did you try out CEdit::LineScroll(...)?
from msdn:
void LineScroll(int nLines, int nChars = 0);<br />
<br />
Parameters:<br />
nLines <br />
Specifies the number of lines to scroll vertically. <br />
nChars<br />
<br />
Specifies the number of character positions to scroll horizontally. This value is ignored if the edit control has either the ES_RIGHT or ES_CENTER style.

just use WM_VSCROLL like this:
::SendMessage(WM_VSCROLL,hWnd,SB_BOTTOM,0);
the hWnd is the handle of edit box;
good luck!

Hi,
Did any one know how to get a message in Visual C++ when a smart card was inserted or removed ?
Thanks Very much
|
|

I don't know the answer but asking the questions 3 times in two days isn't going to help you get an answer.
Why don't you just read all of the messages posted on this board for the last two weeks? I do that all the time and I seem to recall someone asking a question about how to detect new hardware inserted and registering your application for notification from the operating system.
As a last resort, do a search. Though, I know that can be hard getting the right keywords.

How to view in messagebox
sample file: http://dziennik.naczasie.pl/testfile.txt
if I try messagebox return only """
|
|
|
|
|
Load file contents to the string (CString or simply char*), then display it. Consider scrollable edit box or some decent UI instead of a MessageBox, unless the file is always small and formatted in a way that MessageBox can handle.

BB

hello,
I just recently got visual studio given to me. I am very interested in programming and I would be very appreciative if someone could point me in the right direction. I know nothing about C++ or any other computer language for that matter. Please help me.
My AIM screen name(s) are: Orch1d 7, FiveInchesOfFury
Thank you

download a c++ book (from any University for free), read line by line, try line by line.
then come back to post second question.

I'd strongly recommend Beginning Visual C++ 6 by Ivor Horton. It starts off with a pretty good introduction to the C++ language, and it has some very nice examples for you to try. The God-forsaken painting program the author focuses on throughout the book is a little frustrating (unless the sole reason you bought Visual C++ was to write a simple painting program), but it covers most major topics pretty well. I'd also recommend buying the physical book. I really hate reading books from PDFs, but maybe that's just me.
Also be sure to check online for examples. If you have a problem to solve, there is almost certainly at least a partial solution somewhere online.
As for Visual Studio .NET (you didn't say which version you got for free), I don't own any books on it, so I can't really comment on any of them.
Good luck and asincludeh10 said, do post more questions

add few message handlers in some suspected windows (i.e. main-frame) to see where the message is sent.
it must be somewhere, then transfer it from the window to required place.
includeh10
|
|
|
|
|
sorry,but can u explain more .
how i can handel meassage and which message??
|
|
|
|
|
i.e. the button ID is ID_TEST, add a menu item as ID_TEST.
in main-frame, wait for the message (messge=WM_COMMAND, wParam=ID_TEST).
"wait" means u put a messagebox there then click the menu to see if the message is processed to the window.

ok,i will try it.

I have an unusual task: slow down process in Windows(I have only executable(s) of this process.
If there's no way to slow down stand-alone process, I could slow down oll system. What is the better way to do it? Is it effective to make infinite loop process with real time priority.
