Well, I currently have an dialog application which polls a joystick and uses these values to perform an operation on external equipment. However, I will be using video which must be full-screen so the dialog will lose focus. The dialog only reads the joystick values when it has focus. So i need the dialog to read the data when it loses focus.
Maybe, a dialog application is not the best method

You can put a timer in your dialog and do your polling there.

If you want to minimize,
then WM_SETFOCUS message handler or OnActivateApp,
Call
ShowWindow(SW_MINIMIZE) for minimizing
ShowWindow(SW_HIDE) for hiding the window. Hope I answered you

Thanks for the advice and time. 
The problem was to do with the joystick cooperative levels in the DirectInputDevice. Changing the cooperative level allowed the application to have access to the device when running in the background.

Hi,
Ive done some searching with no luck to get the ip of client connected to a socked using winsock.
heres what ive got which may be totally off...
accept( ListenSocket, (SOCKADDR*) &clientip, NULL);
int strangeip=clientip.sin_addr.s_addr;
strange ip reports some strange int... cant figure out how to get the actual ip there.. or convert the u_long to hostent.. i think i can get hostent converted to ip however cant get that far...
any help would be appreciated...
|
|

|

See if this helps
inet_ntoa(client.sin_addr)
Somethings seem HARD to do, until we know how to do them.

hmm.. getting 204.204.204.204 from the inet_ntoa.. which probably means.. that part of the accept is not going to help me get the ip... i assume..
ive seen this before....
char hostname[256]; struct hostent *host; in_addr ip; gethostname(hostname, 256); host = gethostbyname(hostname); memcpy(&ip, host->h_addr, sizeof(ip)); printf("First host IP is: %s\n", inet_ntoa(ip));
which seems to get the local ip.. which is not what im trying to do...
|

I think you can get the IP in this manner:
sockaddr_in clientAddress;
accept( ..., (SOCKADDR*)&clientAddress, ...);
in_addr inAddr = clientAddress.sin_addr;
Now the four components of IP, from left to right, are in inAddr.S_un.S_un_b.s_b# members:
printf("The IP is: %i.%i.%i.%i",
inAddr.S_un.S_un_b.s_b1,
inAddr.S_un.S_un_b.s_b2,
inAddr.S_un.S_un_b.s_b3,
inAddr.S_un.S_un_b.s_b4);
Hope it helps.

Hi..
Actually there is no any error for the program. The program is correct and can be run.How can i get 4 circle shape instead of square?
There are some command missing for the program.
U hv to include this on the top of the program.
After each #include, please key in the folowing code for each #include
#include windows.h
#include gl\gl.h
#include gl\glaux.h
#include math.h
Please delete this and replace with the above code.
#include
#include

Thanks

Dear all,
Is there an API function that will hide a partition and/or folder in a USB Memory Stick, so the folder will be inaccessible from other computers - that is protecting the contents of the memory stick. Ideally, the program should be stand alone, and no installation would be required on any computers.
Thanks in advance
Derek

thanks for your reply, SetFileAttributes worked successfully, but i need something that is OS independent, as if the user selects to view all files, the hidden files would also be disclosed. I need to hide a folder on a USB stick which would only be revealed if the correct password is entered using a program independent on the OS settings...im thinking of having some settings at FAT32 level, some way or another
thanks in advance

no way...
hidden file notion is OS/FS dependant, simply because not every OS/FS can choose to implement such a feature.

hi thanks for your reply...
yep it seems to be impossible, i didnt find any good programs that feature this...however, once i had a USB memory stick and the program that came along with it allowed to partition the USB memory stick in two, one is unprotected, and the other partition is only revealed if the correct password is entered
i was wondering that this could be accomplished by modifying the FAT32 table indirectly through some API functions...
thanks once again for your assistance

i don't think so. FAT32 FileSystem don't store security infos... you would have to format your partition into NTFS for example, but on a USB stick, i doubt this could be achieved.

My guess is that they did some kind of trick with the partition table, making the protected partition invisible until the correct password had been given.
