Hello, I'm developing a application that does the communication wit TCP/Ip between two computers and send files between them, but i have some questions like i want to know what is the best way to develop it, for example socket or i don't know. Somebody can say me the best way ant what libraries can i use for develop it.
Thanks.

Thanks Ravi, but i have other question because i think that u know a lot. With this example i can see how can i implement my communication betwwen 2 computers with files but my applicacion start when i connect with a USB device and i have to pass the ID of the device to the server and the server has to see what files can download this device from the server. And i want to know how can i integrate my program that control the USB device and i know the ID of the device to pass this ID to the server and what will be the best way to develop the permissions in the server ( with a data base, only with text files, can u help me?, it's only to say to the client that whatever device has permiss to download for example only 5 files).
Thank you very much for your help.

You could check out http://www.msgconnect.com/[^] I haven't used it, but it looks good.
And as Ravi said there are lots of articles here on tcp/ip. Would be nice to abstract your problem out to higher level concepts than tcp/ip though.

Well that is up to you (unless you have someone to bounce your ideas of of)!

I understand why you asked this question, but we both know that it is bogus.

This is not an uncommon message from ClassWizard. I get it about 30% of the time when creating a new class. To ensure that your class gets properly added to the project, exit the IDE, delete the temporary files (e.g., .opt, .ncb, .aps, .clw) , and re-open the project. The next time you invoke ClassWizard (Ctrl+W), all should be well.

thank you, I get it. but why ? Is that vc's bug?

Yes, it is a bug. I see the same thing happen on all my systems (about 5 current - many in the past). Does not seem to matter what OS or if virus scanner, spybot scanner, firewall, etc. are installed and running or not.

Hi, I am having a strange issue with StretchDIBits on Win2000 Server and multi-monitor. If the primary monitor is smaller then the secondary, and it is at the bottom.
When using StretchDIBits and goto PrintPreview I initially get a large white unpainted area in the preview window. The non-white part appears to be the same depth as the primary monitors height. Now if I invalidate the white parts, drag some other app over it, it now paints the invalidated white part with the correct bit of the image. Minimise then Restore the white part is back.
If I try using SetDIBitsToDevice this works without any white bits. But I must use StretchDIBits.
I have tried a number of other apps and if they use StretchDIBits, they also have issues.
Anyone got any thoughts
Cheers

Just an idea here...
Perhaps the StrechDIBits is internally limiting itself to the coordinates of the initial device resolution?
Instead, maybe you can try this...
Create a memory DC the size of the combined monitors.
Perform the StrechDIBits into the memory DC
Copy the memoy DC image to the 'virtual' DC of the combined monitors.

Great idea, we already do this code for double buffered screen drawing code. I have already tried to modify this. But we still get the same problem. I am also trying to use the good old MFC Sample DIBLook and this also suffers the same problem.
"Create a memory DC the size of the combined monitors"
Do you mean a CreateCompatibleDC(pDC)?
|
|
|
|
|
Yes, and I reiterate this is what I would 'try' since I have not solved this problem before either.. 
A memory DC exists only in memory. When the memory DC is created, its display surface is exactly one monochrome pixel wide and one monochrome pixel high. Before an application can use a memory DC for drawing operations, it must select a bitmap of the correct width and height into the DC. To select a bitmap into a DC, use the CreateCompatibleBitmap function, specifying the height, width, and color organization required.
You might need to CreateCompatibleDC() then CreateCompatibleBitmap() (this bitmap is just to force the compatible DC into the correct color depth and dimensions). Then perform your StretchDIBits into the 'compatible' DC. If you are lucky follow all that with a single copy operation of this compatible DC to one representing the entire 'screen' (across the two monitors), otherwise, you will need two copy operations, one targeting the DC of each monitor.

We already use this method for flicker free screen rendering (double buffering). We did not use the double buffering for printer DC. I have now tried this double buffering for a print preview DC and the problem still exists.
Looks like a Microsoft bug report time.
Thanks for you thoughts

How can i change the color of the title bar of my dialog/sdi/mdi. I dont want to use a seperate class for this purpose.
|

Hello Wasif
As far as i know color of the title bar of any window is decided by the currently applied theme or selected color in the "Appearence" Tab of "Display properties" System dialog.
i guess by some way or other if you could get that system Dialog and change these settings programatically but doing this will change title color of all windows. or you could also try to search about HTHEME in MSDN
any ways i hope u will get some clue from this message and will start thinking in a different direction.
All the best

As mentioned by Muhammed, the Title bar colour is determined by
your current colour scheme. If you want to create your own unique title bar window, you probably have to handle the drawing yourself.
This would probably involve handing
the WM_NCPAINT message. I don't think there is any lightweight solution to your request, but if you still want to pursue that idea, there are a few articles on CP about creating custom windows title bars.

Hi, all
I'm adding items to the list control:
for (i = 0; i < pDoc->GetSize(); i++)
{
LV_ITEM lvi;
CMovieData* pMovie = pDoc->GetMovie (i);
lvi.mask = LVIF_TEXT | LVIF_PARAM;
lvi.iItem = i;
lvi.iSubItem = 0;
lvi.pszText = new TCHAR[]; // this line is 63
_tcscpy (lvi.pszText, pMovie->Name);
movList.InsertItem (&lvi);
lvi.mask = LVIF_TEXT;
lvi.iImage = i;
lvi.iSubItem = 1;
_tcscpy (lvi.pszText, pMovie->GetGenre());
movList.SetItem (&lvi);
}
After program stopping I get a message:
Detected memory leaks!

The 63 line I've marked. Is it possible to delete in some way the strings? Thanks.

The pszText variable only requires the pointer to your displayed string. Because you are already storing the textual information in your document, you only need to set this variable to your string array.
Try this:
for (i = 0; i < pDoc->GetSize(); i++)
{
CMovieData* pMovie = pDoc->GetMovie(i);
LV_ITEM lvi;
lvi.mask = LVIF_TEXT | LVIF_PARAM;
lvi.iItem = i;
lvi.iSubItem = 0;
<font color=red> lvi.pszText = (LPCTSTR)pMovie->Name;</font>
lvi.iImage = i;
int pos = movList.InsertItem (&lvi);
movList.SetItem(pos, 1, (LPCTSTR)pMovie->GetGenre());
}
[EDIT]
This will eliminate the need to create unmanaged memory allocation which resulted in your memory leaks.

In this case, you will need to get a pointer to the underlying string array.
One suggestion would be:
..
lvi.pszText = pMovie->Name.GetBuffer(0);
pMovie->Name.ReleaseBuffer();
..
