I want to draw a virtual window when dragging dialog frame to change its size,and draw all controls and dialog
when releasing left mouse button. How to implement?
|
|
|
|
|
use CRectTracker to track down the movement and then when you use the L button up, you have the new rectangle (held by CRectTracker) to place your dialog within.
hope this helps ya

Hey
When I run my prog the size visible in the task manager goes up by about 5mb each second. I have searched for information about memory leaks but most is about remembering to delete memory set with new, malloc , etc.
My prog only uses STL and a couple of pointers to arrays... how can I see which lines of my code are causing the problem??
cheers

If it's an MFC program, then starting the debugger will show you in the output window the memory leaks when you close your program.

If you are using STL it might be possible that you are passing these STL arrays in a function as a paramter or returning from a function. Check out if you are using a normal copy or reference copy.
This might shoot up the memory used though not using new/malloc.

I am passing stl vectors and returning them. Some of the fuctions have reference parameters.
So basically at the end of each function I need to call vec.~vector() ??
cheers and thank you

program might consume more memory if you pass the array this way
<br />
void foo(vector<int> vArray)<br />
{<br />
}<br />
<br />
try doing<br />
void foo(const vector<int> &vArray)<br />
{<br />
}<br />
<br />
or<br />
void foo(vector<int> &vArray)<br />
{<br />
}<br />

it consumes more memory, but it doesn't leak the memory...
|

Please see the initial question posted
""When I run my prog the size visible in the task manager goes up by about 5mb each second. ""
This can happen without memory leaks too. using STL
Hence the guess.
Did it help?

i had read && understood his question.
what he desscribes looks really like a memory leak because if it was a huge allocation, it would happen depending on what he does thru the application, and it would certainly allocate a big memory block once, and stop then.
what you answered is not a solution to fix memory leaks, even using STL AFAIK.
it's much a good habit to use when dealing with big objects as function parameters (and not only STL containers).
and it's not because he changes his functions signatures by using references that his memory won't increase that fast... (maybe less each second at least, but that's all).

MyDialog.cpp
BEGIN_MESSAGE_MAP(CMyDialog, CDialog)
ON_WM_CONTEXTMENU()
END_MESSAGE_MAP()
void CMyDialog::OnContextMenu(CWnd* pWnd, CPoint point)

// TODO: Add your message handler code here
CMenu menu;
VERIFY(menu.LoadMenu(IDR_POPUP_MENU));
CMenu* pPopup = menu.GetSubMenu(0);
ASSERT(pPopup != NULL);
pPopup->TrackPopupMenu(TPM_LEFTALIGN | TPM_RIGHTBUTTON, point.x, point.y, AfxGetMainWnd());
}

when you have to post some code, use the <pre></pre> tags instead of bolding the text...

Hi there !!
Ok ! now this may sound little wild but what is the exact tecnical diffrence betwwen the language C and C++.
|
|
|
|
|
C is a quite old language, and don't know at all about all the OOP stuff...
C++ is OOP however, but as it was build/based upon the C language, it kept much of the functionnalities... so, many beginner confuse both languages.
|
|
|
|
|
I think the big difference reside in how you use the language also. You can use C++ language and still write C code, using the C++ standard doesn't mean that you write C++ code.
The way to view C programs is more procedural, which means that you have a sequence of instructions to execute (that can be in separate functions).
C++ is more object oriented (if you start with that idea in mind of course, otherwise you can still write procedural programs): it is more an interaction between objects, how they are used and how they interact with each other.
|
|
|
|
|
|
keep in mind:
C is a procedural language.
C++ serves the OO design

I have to make server which should be able to serve about 6 TCP connections per minute in every minute in one day. Clients establish TCP connections with server via GPRS tehnology. Amount of data which server and client exchange in one connection is about 100kB. I need advice about technology which I should use for server: Microsoft tecnology(MFC sockets, API, I/O completion ports) or java technology. Can java meet requested performance for server? Does anybody have experience with this problem? Thanks.
