You want to pass the SOCKET to the thread procedure correct?
Declare your class-member thread procedure as
static DWORD WINAPI listener(LPVOID lpParam);
Write the function something like this:
DWORD WINAPI myclass::listener(LPVOID lpParam)
{
SOCKET s = (SOCKET)lpParam;
... do stuff with the socket...
return 0;
}
Create the thread something like:
HANDLE Handle_Of_listener_thread = 0;
Handle_Of_listener_thread = CreateThread( NULL, 0, listener, (LPVOID)s, 0, NULL);
Better?

I have a Image on my dialog this picture is on the WM_ERASEBKGND and its work fine but I have a problem
when I move my program or if I move a program on my program then Mem Usage of my program increase How can I solve this problem. And I have another question
if I use of a code like this on WM_PAINT It increase PF Usage and Mem Usage of my program or no
<br />
void CMyPicture::OnPaint()<br />
{<br />
CPaintDC dc(this); <br />
CRect rect(0,650,830,520);<br />
CBrush m_Brush2;<br />
m_Brush2.CreateSolidBrush(RGB(255,255,255));<br />
dc.FillRect(&rect,&m_Brush2);<br />
m_Brush2.DeleteObject();<br />
}<br />
Thanks

No 
Are you leaking resources in your WM_ERASEBKGND handler??

Thanks for your help I used of this code but when I move a program Mem Usage of my program on TaskManager increase
Is it problem does my code has problem
I read Image on with
m_Image.Load<code> OnInitDialog() method<br />
<code><br />
<br />
BOOL CMyPicture::OnEraseBkgnd(CDC* pDC)<br />
{<br />
Image.BitBlt(pDC->m_hDC,0,0,593,420,0,0,SRCCOPY);<br />
return TRUE;<br />
}<br />
my code is this only but I have this problem
Thanks

Hmmm are you sure that's all you do in OnPaint() and OnEraseBkgnd()?
Your OnEraseBkgnd() wouldn't compile as you've shown it here.

It's ok
probably you don't neet to call DeleteObject
(destructor will do it for you)
Anyway, for your example is better use FillSolidRect()
and you dont have to worry about memory at all

Thanks for your help But why Mem Usage of my program increase can you help me
Thanks

If you want this question answered, you need to post some code. The IDE will actually try to show you where the leaking memory was assigned, is it in your paint code at all ?

Hey good people,
I'm a 2nd year IT student and i desperately need some help on how to implement network capability into my programs .
I got some tutorials on winsock2 but i dont know where to start. The tutorials i got all assume you already a genius programmer. If anyone know where i can get some winsock2 tutorials for beginners please forward me a mail if it's not to much to ask 205017517@cput.ac.za or if you can offer any help in this regard i would greately appreciate it.
Thank you everyone:
Phoenix

The MSDN library has much info...Here's a good place to start
Windows Sockets 2[^]
You don't need to necessarily be a "genius programmer" but it's so much easir if you have at least
basic knowledge of Windows programming for messaging and user interface plus knowledge of the
network protocol(s) you'll be using. Sockets is the easy part

Do you have any C/C++ programming experience? You said you are a beginner, so you will probably want to work on basic C/C++ programming before you jump into network programming, otherwise you are likely to be writing code and have absolutely no idea what it does ... which will make it impossible to debug.
If you insist on jumping into network programming anyway, try this link to get you started.

my project basically deals about displaying information of processor, memory, ram, cache etc. like BenchMark tools.
so i would like to get some help and if any one of the codeproject member can suggest me as far possible.
hopping to get some help.

I don't know how to do it, but I would eliminate your e-mail addresses from the message, you will be heavily spammed if any spam guy finds thos addresses, and everybody will be able to answer your uqestion as I've done by clicking the answer button.
Sorry for not answering your question...

>>hi everybody
Hi Dr Nick!
I'm not sure about the JNI stuff (wrong message board for that) but some Windows APIs may be
helpful...here's a start:
GetVersionEx()
GetSystemInfo()
GlobalMemoryStatusEx()

Is it possible to insert an element directly into it's 'right' place in an ordered vector, instead of using push_back() and then sort()? If not, is it possible with a list?
Thanks,
Avi.
|
|
|
|

You can use insert, but you have to march through the vector/list to find the correct location to place it.
Alternatively, you can use the set template which will always be sorted (but requires uniqueness) or multiset (which will be sorted and stores non-unique items in a vector at each location).
If you decide to become a software engineer, you are signing up to have a 1/2" piece of silicon tell you exactly how stupid you really are for 8 hours a day, 5 days a week
