Hi,
When I delete the thread from the m_pThread (CWinThread*) it crashes. So, I am using the simple Win32 API function CreateThread and TerminateThread and there is no memory leaks.  Why doing complex as we can do simple?
Indeed, the driver is poorly implemented. It's a USB driver for HP calculators (shipped by HP) and it does not handle correctly the overlapped IO (the system crashes when I use overlapped IOs), if it would have handle them correctly, of course, overlapped IO would have been much more simple. But now, with this brutal algorithm of calling ReadFile in a thread and kill the thread after an amount of time and repeat the operation until something comes works fine now  But I'm agree that overlapped IO should be the best choice. Of course, using overlapped IOs, is the first idea that came in mind. 
There is no spoon.

Hi
I am trying to add a dialog to an existing project.
I add the resource file .rc then add the dialog and double click on it an the class creator/wizard thing appears so I enter the class name.
Now I try to add a button and test it by adding a show message to it's event handler.
The problem is, it doesn't compile and the error is:
IDD_DIALOG1 = undefined
enum {IDD = IDD_DIALOG1};
Help!

why did you copy the .RC file ???
as far as i know, when you create a dialog, you set its ID. the same when you add a button to the dialog... then, you can associate an event handler to that ID...

I created the .rc file i.e. added it to the project
then the dialog is added as a child of the .rc file
Am I doing this all wrong?
Can you step me through what you would do to add a dialog with a button?
Cheers

Exactly how did you do this?

It wasn't defined! But now I get lots of errors saying that everything is already defined in a .obj file.

Sorry, I'm not your personal teacher and I'm not doing your homework for you.
If you're too lazy to search an article yourself, then I can't help you anymore.
Don't try it, just do it!

I am new to C++ and I am trying to write a small program that would backup an access database file from the hard drive to a zip drive.
I would appreciate any help.
Thank you.

Sounds very much like "do my homework for me please".
But I don't care....
Get a library for creating zip files from the internet, and use it.. that is the rough description of what you have to do.
Don't try it, just do it!

Sorry I have not been in school for a long time....., I have not used C++ for a few years and was trying to relearn it. I have been trying to figure out how to use the ifstream and ofstream with no luck.

Can't you use CopyFile() or SHFileOperation()? If not, then I guess I don't understand the question. Is there something special about a Zip drive (I've never used one)? Don't you just copy files to it like any other drive?

Nothing special about ZIP drive, except you might (more like probably) get error if no disk is in it. Otherwise, pretty much just like a floppy or any other read/rite drive. I also suspect the CopyFile or SHFileOperation will work just fine.

Hi,
I need to write dll for another MFC application.
I've wrote the dll using MFC DLL wizard (regular dll using shared MFC dll).
In my DLL header there is th followung declarations:
#define TCPDLL_API __declspec(dllexport)
TCPDLL_API int WINAPI FLRInitializeIP(IPStruct *Server,int num_of_radars);
and in my "dll.def" there is the next declaration:
FLRInitializeIP @1
Also,the implementation of the function is:
TCPDLL_API int WINAPI FLRInitializeIP(IPStruct *Server ,int num_of_radars)
{
struct hostent *Host;
SIZE_T t=100;
char *host_name = new char[100];
gethostname(host_name,t);
Host = gethostbyname(host_name);
Server->HostIP = inet_ntoa(*((struct in_addr*)Host->h_addr));
delete []host_name;
Server->Num_Of_Connected_Clients = 0;
Server->ListeningSocket = INVALID_SOCKET;
Server->Num_Of_Radars = num_of_radars;
if(CreateTCPServerSocket(Server) != LISTEN_SUCCESS)
return 0;
return 1;
}
Finally,I'm using the dll :
typedef int (CALLBACK* FLRInitializeIP_PROCCESS)(IPStruct* ,int);
void CDLLTestDlg::OnListenButton()
{
HINSTANCE hLib;
FLRInitializeIP_PROCCESS FLRInitializeIP;
IPStruct Server;
int result;
hLib = LoadLibrary("TCP_DLL.dll");
FLRInitializeIP = (FLRInitializeIP_PROCCESS)GetProcAddress(hLib,"FLRInitializeIP");
result = FLRInitializeIP(&Server , 1);
m_List.AddString(Server.HostIP);
FreeLibrary(hLib);
}
Well,I don't get compilation errors,but if the return value
of FLRInitializeIP() is anything else but "void"- i get run time error(something about convention error...).
But, if the return value is "void" there is no error.
When i'm debugging my code - the function works fine and the
error accurs after
return 0
or
return 1
Can anyone help me with this error?
Is there good tutorial about dll programing?
Maybe I've wrote the wrong DLL project?
Regards,
Eli

Why are you using a MFC dll for a function that does not use MFC?
