Are you wanting to spawn, and view the output of, a console application from your code?

I have code that writes to a console but I can't see the console because it is a windows forms application i'm writing

I'm confused. If you are already writing to the console window, can't you just write the same text to some other location (e.g., a form)?

The code that writes to the console is to connect to a server and I don't want that to be shown on the form for the user to see but in the background in a console. It connects to the server fine but just doesn't display in a console window.

How are you doing this?

I've wrote an interface using windows forms and when the user clicks a button on the menu then this executes code from another class that connects to a server. The code that connects to the server was originally a console application and I have incorporated that code into the interface.

I appreciate your help but I don't want to waste your time as I think this is not that important.

So what is it that you are expecting to be written to the console window?

This is what I expect to see in the console window:

I don't want this information to be displayed to the user on the form but as a background job in a windows console.

I'm just not sure why the console is not showing up.

Even if I just write a simply command in the form as:

<br />
Console::WriteLine(L"Hello");<br />

A console is not shown with the word Hello.

Sorry I’m going to be offline now and won’t be on until tomorrow. I would to thank you for looking into helping me with this problem.

Is this VC++? Managed?

I have a Visual C++ book that has windows forms in it but I think it goes under managed

So you might want to re-ask your question here. There are several ways to spawn a console window and write to it, so I can only surmise that managed vs. unmanaged code handles it differently under the covers.

Visual Studio VC++ 6 development system worked fine so far on Windows XP computer, but now on my Windows Vista class wizzard looses classes and on laucnh and each compilation session there a message appears of incompatibility with Windows Vista. How can I solve this problem ?

Have you searched for the exact error message?

turning off UAC solves the compilation warnings.

class wizard has always been a little forgetful, regardless of OS, so i didn't notice any change in Vista.

Dear all:

I am trying to use the hash_map in C++ in VS2005.NET.

The code is like:

<br />
#include <hash_map><br />
...<br />
...<br />
    hash<const char*=""> H;<br />
    size_t h = H("ca");<br />
</const></hash_map>

I want to generate the hash value for the string. This code works perfectly in Linux but in VS2005 it complains that:

1>d:\project\vs2005\c++\gmesh\gmesh\ml_geodesic_gridpoint_index.cpp(54) : error C2065: 'hash' : undeclared identifier
1>d:\project\vs2005\c++\gmesh\gmesh\ml_geodesic_gridpoint_index.cpp(55) : error C3861: 'H': identifier not found

It seems that the compiler can't find the hash definition. Does anyone have idea to solve this problem for me please?

Thanks

Does the hash_map file exist? Can the compiler find it? If you right-click the #include statement, can you opt to open the file?

Indeed it exists (at least on my system, VS2005). On the other there's no hope to find the hash class itself (again, on my system).

Hello everyone,

I listed for scenarios. I think case 1, 2 and 4 are object's destructor is called during stack unwinding caused by exception. Scenario 3 is not stack unwinding and it is normal function return (not exception) triggers the destructor of the object.

Scenario 1:

try{
    local object defined;
    exception throws;
} catch ()
{
    catched;
}

Scenario 2:

try{
    local object defined;
    exception throws;
} catch ()
{
    not catched;
}

Scenario 3:

    local object defined;
try{
    exception throws;
} catch ()
{
    catched;
}

Scenario 4:

    local object defined;
try{
    exception throws;
} catch ()
{
    not catched;
}

thanks in advance,
George

Hello!

Following problem:
GetComputerNameEx called with parameter ComputerNamePhysicalDnsHostname didn't return the DNS name - it returns the NETBIOS name.

Do you have an idea whats wrong with the code??

Thanks in advance.

Greetings
Amd Opteron

Here is the code:

#define _WIN32_WINNT 0x0501

#include <cstdio>
#include <cstdlib>
#include <windows.h>
#include <tchar.h>

int _tmain(int argc, TCHAR *argv[]) {
TCHAR szHostname[MAX_COMPUTERNAME_LENGTH + 1];
TCHAR szHostname2[MAX_COMPUTERNAME_LENGTH + 1];
TCHAR *szDnsName;
DWORD dwSize;

GetComputerName(szHostname, &dwSize);

GetComputerNameEx((COMPUTER_NAME_FORMAT)ComputerNamePhysicalDnsHostname, NULL, &dwSize);
szDnsName = new TCHAR[++dwSize];
GetComputerNameEx((COMPUTER_NAME_FORMAT)ComputerNamePhysicalDnsHostname, szDnsName, &dwSize);

dwSize = sizeof(szHostname2) / sizeof(TCHAR);
DnsHostnameToComputerName(szDnsName, szHostname2, &dwSize);

_tprintf(_T("'%s'\n'%s'\n'%s'\n"), szHostname, szDnsName, szHostname2);

delete[] szDnsName;
return EXIT_SUCCESS;
}

The code works with me, and it returns the name of my computer.
Whether the Netbios-name is any different from the DNS-Hostname is determined by your administrator.

Let's think the unthinkable, let's do the undoable, let's prepare to grapple with the ineffable itself, and see if we may not eff it after all.

It simply returns the name that was established at system startup, when the system read it from the registry. That must be the NetBIOS name in your case.

This should be the corresponding registry key:

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters]
"Hostname"="your-hostname"

On my machine stands there the NetBIOS name and NOT the DNS name.

Do you know a way how to tell Windows to set this key to the proper value?

Unfortunately no, as I'm not familiar enough with NetBIOS and DNS. What does gethostname() do for you?

gethostname() from the WinSock library also returns the NetBIOS name... Frown | :-(

Any idea?
