using LVM_SORTITEMSEX message
You need to pass it a function that compares two items and says whether the first goes before the second. The prototype is a global or static function
int CALLBACK CompareFunc(LPARAM lParam1, LPARAM lParam2, LPARAM lParamSort);
typically, you pass a pointer to the struct with the window handle of the list control and the information how to sort as "paramSort".

I have a question.How to realize a multithreading at use of sockets. More particularly: there is a server which accepts data from the client in a secondary thread, how many clients are so much streams. Me the problem of realization of the given problem interests.

Meat man, meat. Try to not use translators anymore, please.
As for the case of your, use accept to redirect connection to randomly generated port, then create thread which will use that newly created socket, and return immediately to accept for another connection.
It could look like this:
do
{
newsocket = accept(initial_socket)
create_thread(newsocket) {
work_with_new_socket();
...etc...
};
}
loop (get back to the beginning, mean accept);

I just switched from a debug build to a release build using my fairly new VC8 compiler, when I was confronted with many warnings I never expected. Most of these warnings relate to my using C type casts (at least I think, I didn't fix them all yet). One warning in particular I am unable to correct:
_stprintf_s(buf,255,_T("SYNTHETIC:%8.8X"), reinterpret_cast<DWORD>(this));
Which gives me a pointer truncation error. I know it is safe to ignore, but in my view warnings are there to tell you you something, in this case "Hey lamer, code this better!!!".
Also, since these are warnings and not errors, the compiler tends to not repeat the warning on further rebuilds. How can I change this? If I remember in VC6 I had to toggle the "incremental rebuild" option, but I have so far been unable to find it in VC8.
And, one last question, how can I view the same warnings when doing a debug build?

The problems was due to the "64 bit compatibility check" option being set in the options for release builds. Disabling the option has resolved the problems, however it does lead me to another question.
Does anybody know of any decent articles about creating 64 bit compatible applications?

The big thing, which you just ran into, is casting pointers to a 32-bit type such as DWORD. You should use DWORD_PTR instead. The _PTR doesn't mean "pointer" (it's a bad choice of name IMO but we're stuck with it), it means "same size as a pointer" - so 32 bits in x86 and 64 bits in x64.

Thanks for the heads up. I was always under the assumption that the *_PTR DID mean "pointer". My own fault for not checking the docs, but with a name like that what is to be expected!
What is it with MS and their typecasts?

hi all i had created the bitmap of whole screen through code,i mean functiosn such as createcompatiblebitmap(),bitblt() etc and then save it works fine
now i want that that size of image(i mean widht and height) should be reduced,so that whole screen fits into small bitmap,i had tried using stretchblt() but it did not work bcos it creates image of same size. i mean reduced image + some black parts also present on image which i dont want.
how to remove those black parts from image.so that color values are present and no black parts where i reduced the widht height.

stretchblt() is the function you need, it shouldn't be painting any black rectangles to your bitmap, so I can only guess you are using it wrong. Perhaps you could show the code sample you are using and we may be able to help you find the errors.

thanks for replay here is the code of its behind the button event,
<br />
int nScreenWidth =:: GetSystemMetrics(SM_CXSCREEN);<br />
int nScreenHeight =:: GetSystemMetrics(SM_CYSCREEN);<br />
HWND hDesktopWnd = ::GetDesktopWindow();<br />
HDC hDesktopDC = ::GetDC(hDesktopWnd);<br />
HDC hCaptureDC =:: CreateCompatibleDC(hDesktopDC);<br />
HBITMAP hCaptureBitmap=::CreateCompatibleBitmap(hDesktopDC, nScreenWidth, nScreenHeight);<br />
::SelectObject(hCaptureDC,hCaptureBitmap); <br />
StretchBlt(hCaptureDC,0,0,((nScreenWidth/2)+310),((nScreenHeight/2)+290),hDesktopDC,0,0,nScreenWidth,nScreenHeight,SRCCOPY);<br />
CImage file; <br />
char str[15];<br />
DWORD filetime=::timeGetTime();<br />
itoa(filetime,str,10);<br />
strcat(str,".png");<br />
char strdrive[25]="C:\\";<br />
strcat(strdrive,str);<br />
file.Attach(hCaptureBitmap);<br />
file.Save(strdrive);<br />
hope it clears my question.

Hi,
XML, HTML, XHTML, etc... are all tree structure based languages, so there's no way to provent you from maintaining tree structure in XML file. Use attributes (eg. Id, parentId) to obtain such functionality.
...
mom
..|-node0 (parent=mom)
....|-node1 (parent=node0)
....|-node2 (parent=node0)
...
Hope that helps,
Regards

I try to use 'KBDLLHOOKSTRUCT' and I get the error undeclared identifier.
When I compile the ForTheKids, it is alright!
Please help!

Is that a console project? If so have you included the header file "Windows.h"?

It is a mfc dialog project!
Both windows.h and winuser.h are included!
Please help!
|
|
|
|

Is there any other error you get? Is that you are using ULONG_PTR as it is? Is that defined? If not, try defining ULONG_PTR as #define ULONG_PTR ULONG* in your stdafx.h
Nobody can give you wiser advice than yourself. - Cicero

I don't get any other error!

_WIN32_WINNT=0x0401
Set this macro in the project setting->C++->Preprocessor definition
|
|
|
|

I think, you need to download latest platform SDK.
|
|
|
|
|
But I can comply the ForTheKid program without any error!
Is it related to any setting problem?
Please help!

Hi all,
I wrote a program that checks whether another process of the same kind is running, and it's working. But my question is will the same program work, if two different computer(user) sessions are open and the they try to open an application (which I have cattered for) more than once.
An example I can give is the following: A user can use remote desktop to login and another user can use VNC which creates more than one user session. The two users do not know of one another and they decide to open an application. But only one session of this application may be opened. Is it possible to check for both of the sessions, to prevent the program from being opened more than one.
Many thanx
The only programmers that are better than C programmers are those who code in 1's and 0's.....
