Anythings possible.
I suggest 2 ways:
First, how about putting the size in the first element? Cheating I know.
Second, put a terminator value in the last element which is used, similar to the \0 terminator in a string in C. But then you have to know some value which will never be used in the array. For example, if the 2-D array is 16-bit signed integers representing ground altitude in feet, use 32767 since Everset is ?? 29000 feet.

A CFormView is a CView which lives within the realm of a CFrameWnd, not a tab control.

Hi all,
I am making one win32 client-server application using VC++.NET 2003. I am using NetworkStream->Write() function to send data. Now I am new in C++ programming and I want to send some BYTE values using this function but I don’t know how can I make array of all BYTEs I have. I know I can make array of BYTE from string using Encoding::ASCII->GetBytes() function but I have raw BYTE data like 0x09, 0x31, 0x21 etc..
Thanks in advance,
Priyank

For instance
BYTE myByteArray[]={0x09, 0x31, 0x21};
If the Lord God Almighty had consulted me before embarking upon the Creation, I would have recommended something simpler.

Thanks,
It works for
BYTE myByteArray[]={{0x09}, {0x31}, {0x21}};
but I want to use the same variable for many time. How can I enter new values after sometime?

No idea. But I wouldn't take it too seriously. The votes that other people gives you does not affect your status and IMHO is only used to reflect people's feelings about the topic.
Nice, if you get top votes, but no skin off your back if you don't.

Yeah, I should try to ignore it though it irritates a bit. It just says playful kids are around! Funny

I would guess it was because you didn't bother to look at the documentation before making your reply that questioned the relevance of a correct statement.

Anyone can vote as they please; they are free to vote you down for no other reason then that it amuses them to do so. I don't see what Chris can (or will be willing) to do about it; he's not about to turn the CodeProject into a dictatorship!

I'm using the win32 API, so I would like to be able to use the SendMessage Function to change the text in these two controls.
eg:
SendMessage(GetDlgItem(hDlg,IDC_TIMESLIDER),UDM_GETPOS,0,0);
*this code is for getting the position from a slider*
Anyone know where I can find the flag for changing text, or for that matter some decent documentation on this?

Hi,
WSAStartup
Have you linked the following lib file to your project:
Library Use -> Ws2_32.lib : Link WSAStartup[^]
_beginthread
Have you included the following header file to your project:
#include <process.h> /* _beginthread, _endthread */
Link _beginthread[^]

Hi all,
I have created a tab control with 4 tab items.2 tab items are disabled initially.Only the enabled tab items must be focussed when the mouse pointer is placed onto the corresponding enabled tab item.
problem i am facing here is even the disabled tab items are focussed when the mouse pointer is moved onto the corresponding disabled tab item
pls suggest me how to avoid getting focus on the disabled tab item
Thanks,
Sireesha

You could try catching the GetFocus event and setting the focus back to the previously-focused tab.

I seen many examples about ListBox,in DrawItem they use the state and the action to decide how the item should be drawn. I am puzzled that what is difference between focus and the select or selected.Besides,is the whole ListBox redrawn when I click the item when the program are running?Could somebody give details~?
Thanks~

In many controls (like a standard listbox) the focus state and selected state are set at the
same time.
Having both states gives custom controls a way to indicate keyboard focus without an item being selected or vice-versa.

In the standard listbox rendering, Focus typically draws a dashed rect around the "current" item and Selected shows the item in color. The difference is useful if you want to e.g. keep the Selected item highlighted when the listbox is not focused.
Usually only the affected items are redrawn. For example, if you have item 1 selected and click on item 2, you'd get draw messages for item 1 (with the selected flag cleared) and item 2 (with the selected flag set), but no draw msgs for items 0 or 3. If oyu *scroll* the listbox you'll get draw messages for all visible (either partially or fully) items, but not for those items whose rects fall outside (above/below) the window's client area.

Hello friends, this me back with a question. I ve got a code snippet for finding the list of systems in a LAN.It lists the computer name and the IP address. Now i wanted to know how i can find the status of the system ie. if it is active or not.
here is the piece i used to found the systems:
for ( unsigned int i = 0; i < BufferSize/sizeof(NETRESOURCE); i++, NetResource++ )
if ( NetResource->dwUsage == RESOURCEUSAGE_CONTAINER && NetResource->dwType == RESOURCETYPE_ANY )
{
if ( NetResource->lpRemoteName )
{
CString strFullName = NetResource->lpRemoteName;
if ( 0 == strFullName.Left(2).Compare("\\\\") )
strFullName = strFullName.Right(strFullName.GetLength()-2);
gethostname( szHostName, strlen( szHostName ) );
host = gethostbyname(strFullName);
ptr = (struct in_addr *) host->h_addr_list[0];
int a = ptr->S_un.S_un_b.s_b1; // 211.40.35.76 split up like this.
int b = ptr->S_un.S_un_b.s_b2; // 40
int c = ptr->S_un.S_un_b.s_b3; // 35
int d = ptr->S_un.S_un_b.s_b4; // 76
lpszSystemInfo = tchBuffer;
// Get and display the user name.
GetUserName(lpszSystemInfo, &cchBuff);
strTemp.Format("%s --> %d.%d.%d.%d",strFullName,a,b,c,d);
pList->AddString(strTemp);
}
}
}
this is a downloaded code friends. but still i want to know how.if we can find the IP address, then there must be a way to find its status. Pls do let me know if anyone of you know this.Thanks (in anticipation)

(If I understand your question correctly ...)
What about the function:
FILE *_popen(const char *command,const char *mode)
You can uses this function to ping the other machine, and know the status.
#include <stdio.h>
#include <stdlib.h>
int main( void )
{
char psBuffer[128];
FILE *pPipe;
if( (pPipe = _popen( "ping 192.168.0.1", "rt" )) == NULL )
exit( 1 );
while( !feof( pPipe ) )
{
if( fgets( psBuffer, 128, pPipe ) != NULL )
printf( psBuffer );
}
printf( "\nProcess returned %d\n", _pclose( pPipe ) );
}
Hope this helps ..
