Strange as this code worked fine for me (i.e., both produced 542). I wonder if it could be a buffering problem (as I see your edited post, this is most likely the problem). Try calling function_2() first and note the result. Also try putting an endl at the end of each cout statement.

You are right it does work. I tried in a clean Doc/View program too.
Odd that it doesn't work in the current program I am working on.
I have OnDraw calling a function to draw but CRect and CPoint value just disappear. I even output the value before the function is called but as soon it's called the value is gone.
This is what happen I use Debug to trace into it
CXX0069: Error: variable needs stack frame

Are you using cout in a GUI application?

Ooops disregard the debug error message. I breakpoint too early.
No cout I am drawing a graph and basically I have it
CPoint pt declare in the View header
int dummy declare in the header also
OnDraw(CDC* pDC){
CRect final;
int x =6, y = 7;
pt = (3, 2);
dummy = 9;
// At this point 3, 2 is still valid
final = function(x, y);
// pt, 3, 2 returns
// Draw final rectangle
}
CRect function{int x, int y){
// pt x = 0, y = 0;
// dummy = 7
CRect temp;
temp = (CPoint(pt.x+x, pt.y+y), CSize(3,3));
return temp;
}
Something like that. I don't understand why my function is having problem accessing pt value but if I declare it as int it would be fine Grrr. pt.x was orignally an int and it worked fine but when I changed it to CPoint pt.x it stopped working.

Are you sure this is right? Set a breakpoint on this statement and notice that the x and y member variables are not what you think they should be. Use an explicit assignment, or use something like:
pt = (2 << 16) + 3; Anonymous wrote:
CRect function{int x, int y){
Is this a member of the view class? In either case, the left curly brace does not match the right parenthesis.
Anonymous wrote:
temp = (CPoint(pt.x+x, pt.y+y), CSize(3,3));
This assignment also looks suspect. I would change it to this instead:
CRect temp(CPoint(pt.x+x, pt.y+y), CSize(3,3));

I just check the memory address.
When I called rect/pt value in the function it reads a new memory address location?!? And it doesn't do that with int.
The View contructor was only called once.

Disregard. I figured out why. I feel very stupid right now
When I chaged declaration to header, I forgot to clear the declaration in the function(I thought I did).
I am surprise the compiler didn't raise flag about the overlap. Hmm I remember there was a declaring function to tell the program which overlap variable to use.

How to display ohm sign, 'Ω', on the screen using VC++, VC++ .net and VB.net? if possible?, What is the project setting?

The console does not support it, and a GUI application will need unicode for that sign because the ANSI converts it to 0x4F and that is 'O'.
Don't try it, just do it!

Why did you delete your answer??
The unicode data for L"Ω" is 0xA9 0x03 0x00 0x00.
=> WORD wOhm = 0x03A9;
Don't try it, just do it!

Hi ds feng,
#ifndef UNICODE
#define UNICODE
#ifdef UNICODE
//ur code for display ohm goes here
#endif
This might solve your problem.
Cheers,

Hi everybody, i have a problem with CEdit, for example
CString s1="Hello World";
CString s2="This is a Test";
//and we have CEdit variable m_edit
m_edit=s1+"\n"+s2;
as you see i want the result to be
Hello World
This is a Test
but CEdit shows :
Hello World This is a Test
though CEdit is marked in properties as "Multiline"
Can anybody help??
Regards

replace \n with \r\n
it will work... even today (April, 1st) 
ps: is your EditBox declared as MultiLine ?

Hi gurus
I'd like to know how I can brutally kill a running thread created via AfxBeginThread?
The core of the function looks like this:
while (!m_dwBytesRead && (nRetries < 2600))<br />
{<br />
m_pReadThread=AfxBeginThread(ReadThread, this, THREAD_PRIORITY_NORMAL);<br />
<br />
nRetries++;<br />
::Sleep(600);<br />
<br />
if (!m_dwBytesRead)<br />
{<br />
}<br />
}
Thanks.
Best regards.

To end the thread, call AfxEndThread from within the thread, or return from the controlling function of the worker thread.
MSDN is your answer.
Don't try it, just do it!

no, not from inside the thread... The creator of the thread, kills its created thread.
<br />
while (!m_dwBytesRead && (nRetries < 2600))<br />
{<br />
m_pReadThread=AfxBeginThread(ReadThread, this, THREAD_PRIORITY_NORMAL);<br />
<br />
nRetries++;<br />
::Sleep(600);<br />
<br />
if (!m_dwBytesRead)<br />
{<br />
}<br />
}<br />

I wish the creator of the thread kill his created thread:
while (!m_dwBytesRead && (nRetries < 2600))<br />
{<br />
m_pReadThread=AfxBeginThread(ReadThread, this, THREAD_PRIORITY_NORMAL);<br />
<br />
nRetries++;<br />
::Sleep(600);<br />
<br />
if (!m_dwBytesRead)<br />
{<br />
}<br />
}

ok, i so repost my question :
don't SendMessge() work with the correct argument ? (i don't remember which, but it might be something like WM_KILL or WM_END)... of course, sent to the correct thread, ie. m_pReadThread

no, the owner of the thread is not a window. the owner of the thread is a CObject derived class. There must be a way for the owner of the thread to kill its own created thread without condition.
