If that's the case
size_t memsize = sizeof(wstring::value_type) * strText.size();
After reading the OP again, I think you're right.

That was more or less my answer, but I have to agree that yours is more elegant 
|
|
|
|

The basic_string::size() returns array size of <element> but not always the same to the character length.
Some new characters have 4 bytes (means wchar_t[2]) in each one character at the new unicode specification named JIS2004 in Japan.
They are so called surrogate-pair and someone said some characters have 6 bytes in some other countries. (I have not checked the specification yet.  )

Do you mean you want to write the wstring to a file? With the null-terminator? Or what?
Anyway - the amount of memory taken up by the string data (i.e. the characters pointed at by the c_str() or data() methods) is size() * sizeof (std::wstring::value_type) (not including the null terminator).

Why am I getting this error?
Error 1 error C2228: left of '.checked' must have class/struct/union
Here's my code.
UpdateData(TRUE);
m_Summary += m_Name;
m_Summary += char(13);
m_Summary += char(10);
m_Summary += m_Address;
m_Summary += char(13);
m_Summary += char(10);
m_Summary += m_Phone;
if (m_Small.checked==true)
{
m_Summary += "Small Size 5.00";
}
UpdateData(FALSE);

How is m_Small declared?

When I do view declaration, it shows me this code.
public:
int m_Small;

That is exactly what the error says.
Fundamental data types do not have any members that you can call that way.

So how should the code be rewritten?
|
|
|
|
|
That totally depends on why m_Small was declared.
My guess would be
if (m_Small == true)
or
if (m_Small == TRUE)

use a #define and then do the checking.

Hi,
Using Vc++ how would i know whether i have inserted disk in the Drive of my machine ..and if inserted how can i get the drive in which i inserted the disk...

You do not need to call RegisterDeviceNotification.
You simply handle the WM_DEVICECHANGE message.
The system broadcasts the message to all top level applications.

Superman is correct in that you simply need to handle the WM_DEVICECHANGE message. I thought you might be interested in the Microsoft support article below:
How to receive notification of CD-ROM insertion or removal[^]
It also describes how to detect the CD/DVD removal by checking for the DBT_DEVICEREMOVECOMPLETE event.

Hi
I'm new to programming - but do use AHK a lot
Where do I start learning?
Is there a tutorial or disucssion board for n00bs?
Thanks

Books, Web sites, etc. Pick up a free compiler (e.g., Visual Studio Express) and just start tinkering.

Yes, the one you are on now is for C / C++ / MFC.

Hi I have a machine with several network interfaces that route through different NAT VPNs.
I've created a testing application that bind()s to one of these interfaces before calling connect(), which works excellent in Windows 7. When I try the same thing in Windows XP, bind() succeeds, but connect() fails with 10065 (WSAEHOSTUNREACH) after some seconds of blocking. I checked Wireshark, and there isn't even one single packet sent/received on each interface.
Any ideas what may be the problem?
Don't try it, just do it!

|

OK, this is probably a stupid question (so I won't be unhappy if I get a stupid answer ) but are you sure the host is reachable through that interface on the XP host? Have you checked with some other network application?

I think I've found the reason..
http://technet.microsoft.com/en-us/magazine/cc137807.aspx
Windows XP uses weak host model, Vista and later strong host model. There doesn't seem to be a way to configure this in Windows XP which is particularly ANNOYING!!

Heya,
So I am trying to work on a make environment that will let me create two libraries and then link against them.
The procedure goes like this:
1. create obj files for lib1 (about a dozen files):
*** Compiling .obj/common.o ...
g++ -O3 -MMD -pipe -pthread -D_REENTRANT -DICL_MEM_DEFAULT_DIRECT -D_GNU_SOURCE -D_LARGEFILE64_SOURCE -DBASE_THREADSAFE -march=native -Wall -Wno-write-strings -Wpointer-arith -Wno-ctor-dtor-privacy -Wmultichar -Wdisabled-optimization -Woverloaded-virtual -Wclobbered -Wempty-body -Wsign-compare -Wtype-limits -Wno-unused -Wuninitialized -I./proto -I/tmp/protobuf-2.1.0/include -I/tmp/protobuf-2.1.0/include/google/protobuf -I/tmp/protobuf-2.1.0/include/google/protobuf/io -c proto/common.pb.cc -o .obj/common.o
2. group the object files together into archive
ar rcs lib/libxproto.a ./.obj/cs_enums.o ./.obj/common.o ./.obj/converged_common.o ...<obj list="">
3. repeat for the second lib.
4. compile a few other objs for MY program:
*** Compiling ../BuildSupport/ExternalLinks/utilities/src/Thread.C ...
g++ -O3 -MMD -pipe -pthread -D_REENTRANT -DICL_MEM_DEFAULT_DIRECT -D_GNU_SOURCE -D_LARGEFILE64_SOURCE -DBASE_THREADSAFE -march=native -Wall -Wno-write-strings -Wpointer-arith -Wno-ctor-dtor-privacy -Wmultichar -Wdisabled-optimization -Woverloaded-virtual -Wclobbered -Wempty-body -Wsign-compare -Wtype-limits -Wno-unused -Wuninitialized -I./include -I../BuildSupport/ExternalLinks/utilities/include -I./proto -I/tmp/protobuf-2.1.0/include -I/tmp/protobuf-2.1.0/include/google/protobuf -I/tmp/protobuf-2.1.0/include/google/protobuf/io -I/tmp/OpenAMQ-1.4b3/ibase/include -I../BuildSupport/ExternalLinks/boost/include/boost-1_39 -I../BuildSupport/ExternalLinks/utilities/include -I../CaddyShack_Common/amq/include -I../CaddyShack_Common/id/include -c ../BuildSupport/ExternalLinks/utilities/src/Thread.C -o .obj/Thread.o
5. the final step is to compile the objs into an executable, link against the libs:
g++ -static -O3 -MMD -pipe -pthread -D_REENTRANT -DICL_MEM_DEFAULT_DIRECT -D_GNU_SOURCE -D_LARGEFILE64_SOURCE -DBASE_THREADSAFE -march=native -Wall -Wno-write-strings -Wpointer-arith -Wno-ctor-dtor-privacy -Wmultichar -Wdisabled-optimization -Woverloaded-virtual -Wclobbered -Wempty-body -Wsign-compare -Wtype-limits -Wno-unused -Wuninitialized -L./lib -lxamq -lxproto <obj list=""> -o ../bin/circuit_accelerator
I get the following error:
./lib/libxamq.a: could not read symbols: Archive has no index; run ranlib to add one
collect2: ld returned 1 exit status
I tried using ranlib after it, and then just relinking still no good. I also am using the 's' flag when doing the ar, meaning i shouldn't have to do a ranlib.
any ideas on why i would be getting this error? Any ideas on how to resolve it? Thanks in advance!!!

Are you sure that this is the correct linking order: -L./lib -lxamq –lxproto?

I would investigate any difference in the build processes of libxamq.a and libxproto.a - it looks like ld can find an index in libxproto.a...
Also - I presume you've deleted libxamq.a and rebuilt it from scratch?
