Hi all,
I am placing a MENU on a Dialog window.
And trying to enable and disable the Menu Items plus putting checkmark and radio, I am overiding the Update<menuitem-name>(... pCmdUI,...) method.
The problem is it not working, I also override the UpdatePopupMenu(...) method of CFrame by using a sample code from MSDN.
Please anybody helps me in this regard.

Update Command UI Handlers Do Not Work for Menu in dialogs.
You can use ON_WM_INITMENUPOPUP message instead of this.

Hi,
I have a project I downloaded from cp and dont know why, but when I try to use some classes that are in many (8 0r 9) files, I get this message:
*.cpp(2) : fatal error C1010: unexpected end of file while looking for precompiled header directive *.cpp
I get about 10 of these when I compile. Does anyone know what this means?
Where is a good place to look up compiler and linker errors?
I have had this problem with classes Ive wrote before.
Thanks.

The best place to lookup errors is in the help.
This means you are attempting to use precompiled headers, but the precompiled header is not present in the files. For Wizard generated files, this is "stdafx.h".
You can turn precompiled headers off for a project in the project settings. For large projects it will slow down the compiles significantly, for small projects, the impact is negligable, though measurable.

It's also possible to turn precompiled headers off for separates files so the project compilation won't slow down too much. Right click on the .cpp file, choose settings, go in the C/C++ tab, select Precompiled headers category and choose Not using precompiled headers
This is a better solution when you need to disable them only for a few files in a big project

Joe Woodbury have detailed it.
the same you can include"stdafx.h" to solve it .

Still confusing,
Goto Project->Settings->C/C++->Precompiled Headers
Select Automatic use of Precompiled Headers.
Thanks.

Thanks. I fixed my problem. You say precompiled header files will speed up or slow down compile?
|
|
|

When the .PCH file is being created, the compile time will take longer. Subsequent compiles will be much shorter. If, however, you have a small project, the difference will not be noticeable.
Five birds are sitting on a fence.
Three of them decide to fly off.
How many are left?

Very easy, add
#include "stdafx.h"
to the files that give those errors.
Make sure it's the first #include though.

Hi, i have a question abt displaying doubles. Under _MBCS the following codes work but how do i display the double under Unicode? Thanks!
char *buffer;
int decimal, sign;
buffer = _ecvt( m_Height, 5, &decimal, &sign );
AfxMessageBox(buffer);
or

How about ansi.org?

Try initializing winsock first:
#include "Winsock2.h"
#pragma comment(lib,"Ws2_32.lib")
int main(int argc, char* argv[])
{
WORD wVersionRequested;
WSADATA wsaData;
int err;
wVersionRequested = MAKEWORD( 2, 2 );
err = WSAStartup( wVersionRequested, &wsaData );
if ( err != 0 ) {
return -1;
}
char host[80];
gethostname(host,80);
LPHOSTENT lpHost;
lpHost = gethostbyname(host);
UINT ip = ((LPIN_ADDR)lpHost->h_addr)->s_addr;
char* addr= inet_ntoa(*(LPIN_ADDR)lpHost->h_addr);
return 0;
}

the codes u gave me are fetching Autoconfiguration IP Address i.e 169.254.159.128
what i need is IP Address i.e 210.24.247.6

The problem is you have more than one ip address. The code above will return the first.
replace h_addr in the previous examples with h_addr_list[1] to get the second.

 but what if the program keeps on shifting from one machine to another where some machine have more than one IP addresses and soem have only one????

It gets very complicated. Any network adapter may have multiple IP addresses. A computer may have more than one network adapters. I am not sure how you can figure out which ip address is the one that is connected to the internet and actually more than one can be connected to the internet.
You can use this code to go through the list of ip addresses:
#include "Winsock2.h"
#pragma comment(lib,"Ws2_32.lib")
int main(int argc, char* argv[])
{
WORD wVersionRequested;
WSADATA wsaData;
int err;
wVersionRequested = MAKEWORD( 2, 2 );
err = WSAStartup( wVersionRequested, &wsaData );
if ( err != 0 ) {
return -1;
}
char host[80];
gethostname(host,80);
LPHOSTENT lpHost;
lpHost = gethostbyname(host);
for(int i=0;(LPIN_ADDR)lpHost->h_addr_list[i] != 0;i++) {
UINT ip = ((LPIN_ADDR)lpHost->h_addr_list[i])->s_addr;
char* addr= inet_ntoa(*(LPIN_ADDR)lpHost->h_addr_list[i]);
}
return 0;
}
