Why? They are gone. Why would you leave the 1 on the end and then say ANDing it with 0xFF will
give a result of 0x00?
Anyway...
The final string -
You call the function with dword == 256 (0x00000100)
The resulting str would be str[0] == 0x00, str[1] == 0x01, str[2] == 0x00, str[3] == 0x00
Say you called the function with dword == 0x01020304
The resulting str would be str[0] == 0x04, str[1] == 0x03, str[2] == 0x02, str[3] == 0x01
These aren't ASCII characters so you can't assume you can safely concatenate using a regular
string function. The resulting "string" is just an array of binary bytes (octets) representing
the dword in "little-endian" order. This would be useful if you are writing the bytes in order
across a network so the other end can reassemble them back in to a DWORD regardless of what type
processor is running.
Are you trying to convert a DWORD to a readable ASCII string?

Contact me if you can help in making this project come to reality. I would like to get it done as soon as possible but also hope not to pay more than $8K for some top programming for IP Camera software. Is this possible? Am I crazy? I may even entertain a share for the programmer in the Business I am starting.:->

Dear All,
I am not sure whether I should post this question in this forum.
If not please let me know the correct forum to post the question.
I am using CPPUnit::XmlOutputter to write the unit test results to an XML file.
The program works as expected and I can see the test results in the xml file.
But I also want to add intermediate results and user defined messages in the same xml result file.
How do I do that?
Thanks a ton,
Arti gujare

Well I won't say that it's the wrong forum but you might have better luck asking in the CPPUnit forums on sourceforge. Not that you won't get an answer here but you are more likely to get a correct answer there.

Can someone give me a simple example of accessing and sending a image to a picture box control at run time??

Try the .Net Framework[^] board.
There's an example in the PictureBox class overview in the docs.

What the function use for get handle of child windows.

You could use either:
EnumChildWindows()
or
HWND hChildWindow = GetWindow(hThisHWnd, GW_CHILD);

If you know the ID of the child you can use GetDlgItem. It works for any window, not just dialogs.

Hi,
void C1View::OnViewIncomeview()
{
AfxGetMainWnd()->SendMessage(WM_COMMAND, ID_FILE_NEW);
CMDIFrameWnd *pFrame =
(CMDIFrameWnd*)AfxGetApp()->m_pMainWnd;
CMDIChildWnd *pChild =
(CMDIChildWnd *) pFrame->GetActiveFrame();
CView *pView = (CView *) pChild->GetActiveView();
CEdit *r1 = new CEdit;
r1->Create(WS_CHILD|WS_VISIBLE|ES_AUTOVSCROLL,
CRect(x1,y1,x2,y2), pView, 1);
CEdit *r2 = new CEdit;
r2->Create(WS_CHILD|WS_VISIBLE|ES_AUTOVSCROLL,
CRect(x3,y3,x4,y4), pView, 1);
r1->SetFocus();
}
I have this piece of code in a function of a called by the application when an icon is clicked on the toolbar.
Now if I go to some other function of the same class and that function moves the caret from one edit box to another
What has to be done?
Thanks

Hi all,
Could someone please help me with the following problem:
How can I wait for a acknowledgement from another device when I have sent it a piece of data throught the serial port. (before sending the next piece of data).
I'm using VS2K5, and I have done the following:
<br />
..... looping .....<br />
array<String^>^ Text = gcnew array<String^>(10000);<br />
<br />
if (!serialPort1->IsOpen){ <br />
serialPort1->PortName = portNum; <br />
serialPort1->BaudRate = 9600;<br />
serialPort1->Open();<br />
}<br />
<br />
serialPort1->Write(Text[x]);<br />
<br />
:confused: ..... wait for ack ..... :confused:<br />
<br />
array<wchar_t>^ buffer = gcnew array<wchar_t>(10000);<br />
serialPort1->Read(buffer,x,sizeof(buffer));<br />
Thank you in advance

You can set a timeout for the reading: you'll wait until either all the data arrived or the timeout expired.
Check out the SetCommTimeout[^] function and the COMMTIMEOUT[^] structure.

Thanx Cedric ... I'll have a look

hi all,
I am having non-blocking TCP socket, trying to receive in a loop for requried bytes.
I am disconnectiing server by removing n/w cable from m/c running server application.
every time recv() fails with WSAWOULDBLOCK, why?
How can i detect that server died abnormally at client end?
recv() also not returning 0?
following is code
iMode = 1; // non-zero = non-blocking mode
iResult = ioctlsocket(sockMain,FIONBIO,(u_long FAR*)&iMode);
iDataGot=0;
while ( iData2Recv >= iDataGot )
{
// recv single byte at a time
iResult = recv(sockMain,&chData,1,0);
// if zero byte got or any other error
if ( iResult == 0 )
{
//never reach here
break;
}
/* timeout scheme
// check timeout period
DWORD dwCur = GetTickCount();
if ( dwCur > dwTimeout )
{
// timeout occured, so we failed
break;
}
*/
if ( iResult == SOCKET_ERROR )
{
if ( WSAGetLastError() != WSAEWOULDBLOCK )
{
// never reaches here
break;
}
else
{
// always executed.
continue;
}
}
// we got something add into output string
if ( iResult == 1 )
{
// add data,update counter into string and break if all datalen is received.
}
client application calls receive() after 10sec and it timeouts after 10sec if no data arrived. I want eliminate later 10sec. and detect server has died.
Thanks in advance.

Hi,
Can VC++ work with Linux or Unix?

What are the other alternatives of C++ with Unix or Linux
other than Java to handle Visual side of an application

You asked about VC++ not C++. C++ is totaly cross-platform. VC++ is not. The difference is that VC++ contains library that can only target windows operating system (basically).
If you want to have a cross-platform GUI, take a look at wxWidgets[^], it is 'similar' to MFC.
