oh, kernel objects memory leaks are my favorite ones! never clean them after myself
whats the point allocation during the start of the console for say 1000 strings of 256 bytes long and then leaving the program without deleting them.

It is not well designed if it fails to clean up after itself. True, the operating system will clean up most resources allocated by your program after it exits, even when you don't free them yourself. The problem is, it may not free all of them. There are resources in Windows that are not freed automatically when a program exits. This means that your program could leave behind resource allocations that can never be freed without a restart. Dangling allocations could also cause your application to fail the next time you run it. A resource you allocated previously and did not free is no longer available.
The other problem is that, while your program is running, it continually consumes more and more resources. If you don't free them as soon as you are done using them, they are a waste. Those resources aren't available for use by other applications or the operating system.

I am compiling a project which I have modified to allow it to compile for Linux as well as Windows.
All compiles ok, except in VS6, the compiler keeps complaining about missing header files.
The headers it is looking for are the Linux ones which are ifdef'ed out (it is ignoring the ifdefs )
I have turned off precompiled headers, but this doesn't seem to have made any difference...
This seems to be happening in a different 'stage' to the Compiling/Linking, as the executable is created ok.
any ideas?
Thanks...

which files is it looking for ?
|
|
|
|
|
General linux specific header files, needed to compile the code under linux.

How are you doing that ? Post some code so that we can check.
|
|
|
|
|
<br />
#ifdef LINUX<br />
<br />
#include <sys/time.h><br />
#include <X11/Xlib.h><br />
#include <X11/Xutil.h><br />
#include <X11/keysym.h><br />
<br />
#else // LINUX<br />
<br />
#endif // LINUX<br />
And LINUX is only defined when compiled under linux...

|
|
|

Just to make a test: comment these preprocessor definition so you are 100 percent sure they won't interfere and recompile. If this doesn't work, then you probably forgot to put some of the include inside preprocessor definitions. If this works, then you probably declared LINUX somewhere and forgot to remove it.
You can also see which file generates the error, so open the file and check the include part to see if everything is correct.

Try build all or/and delete the old build files. Maybe there is an old version with the headers in it.
If it doesnt help compile every file per hand to get the source of the message.:-X

Tried that 
KarstenK wrote: If it doesnt help compile every file per hand to get the source of the message.:-X
It doesn't seem to be coming from the compiler itself...
(As I said the code compiles and links correctly).
Something else is reading the source files and looking for just the #include's, and is ignoring #ifdef's etc...
I thought it was the precompiled header stuff... but even without that it still does it.

hum, well, even you didn't see it, why have you deleted it, as you reasked it 10 minutes later... moreover, you're on a forum to share, ,not only to get an answer... what's been asked and answered can be found back if someone roam on the forum and search for what or what topic.
edit your posts, but don't delete them when you ask a question.

Hello,
I am having troubles with sending data through RS232. I am using the class from Ramon de Klein:
http://www.codeproject.com/system/serial.asp
There I am working with the simple Serial Class (Overlapped).
My problem is that I can only send 16 Byte all together. If I try to send more than 16 Byte, its sending an empty message and I get a NAK from the other side ( I monitored this with a monitoring tool).
This is what the Overlapped structure is set to after sending data:
<br />
Internal 258 unsigned long<br />
InternalHigh 16 unsigned long<br />
Offset 0 unsigned long<br />
OffsetHigh 0 unsigned long<br />
Pointer 0x00000000 void *<br />
hEvent 0x00000780 void *<br />
As you can see, InternalHigh is set to 16. I dont know why. I cant figure out why I am only allowed to send 16 Byte. The dwInQueue as well as the dwOutQueue is big enough to hold more data.
The problem is that I absolutely have no clue where to search for that problem.
Is there anything that restricts the number of bytes to send?
Which codepart can be relevant for you?
This the write method:
<br />
LONG CSerial::Write (const void* pData, size_t iLen, DWORD* pdwWritten, LPOVERLAPPED lpOverlapped, DWORD dwTimeout)<br />
{<br />
CheckRequirements(lpOverlapped,dwTimeout);<br />
<br />
_ASSERTE(!lpOverlapped || pdwWritten);<br />
<br />
m_lLastError = ERROR_SUCCESS;<br />
<br />
DWORD dwWritten;<br />
if (pdwWritten == 0)<br />
{<br />
pdwWritten = &dwWritten;<br />
}<br />
<br />
*pdwWritten = 0;<br />
<br />
if (m_hFile == 0)<br />
{<br />
m_lLastError = ERROR_INVALID_HANDLE;<br />
<br />
_RPTF0(_CRT_WARN,"CSerial::Write - Device is not opened\n");<br />
return m_lLastError;<br />
}<br />
<br />
#ifndef SERIAL_NO_OVERLAPPED<br />
<br />
if (!m_hevtOverlapped && (lpOverlapped || (dwTimeout != INFINITE)))<br />
{<br />
m_lLastError = ERROR_INVALID_FUNCTION;<br />
<br />
_RPTF0(_CRT_WARN,"CSerial::Write - Overlapped I/O is disabled, specified parameters are illegal.\n");<br />

<br />
_ASSERTE(!m_hevtOverlapped || HasOverlappedIoCompleted(lpOverlapped));<br />
<br />
char bla[255] = {0x0};<br />
strcpy(bla, (char*)pData);<br />
<br />
if( bla[iLen-1] == 0x03 )<br />
iLen++;<br />
<br />
if (!::WriteFile(m_hFile,pData,iLen,pdwWritten,lpOverlapped))<br />
{<br />
long lLastError = ::GetLastError();<br />
<br />
if (lLastError != ERROR_IO_PENDING)<br />
{<br />
m_lLastError = lLastError;<br />
<br />

switch (::WaitForSingleObject(lpOverlapped->hEvent,dwTimeout))<br />
{<br />
case WAIT_OBJECT_0:<br />
if (!::GetOverlappedResult(m_hFile,lpOverlapped,pdwWritten,FALSE))<br />
{<br />
m_lLastError = ::GetLastError();<br />
<br />
_RPTF0(_CRT_WARN,"CSerial::Write - Overlapped completed without result\n");<br />
return m_lLastError;<br />
}<br />
break;<br />
<br />
case WAIT_TIMEOUT:<br />
CancelCommIo();<br />
<br />
m_lLastError = ERROR_TIMEOUT;<br />
return m_lLastError;<br />
<br />
default:<br />
m_lLastError = ::GetLastError();<br />
<br />
_RPTF0(_CRT_WARN,"CSerial::Write - Unable to wait until data has been sent\n");<br />
return m_lLastError;<br />
}<br />
}<br />
}<br />
else<br />
{<br />
if (lpOverlapped)<br />
::SetEvent(lpOverlapped->hEvent);<br />

#else<br />
<br />
if (!::WriteFile(m_hFile,pData,iLen,pdwWritten,0))<br />

return m_lLastError;<br />
}<br />
<br />
#endif<br />
<br />
return m_lLastError;<br />
}<br />
This is how I initialize the com port:
<br />
lLastError = rfi->serial.Open(_T("COM1"),10000,10000,true);<br />
if (lLastError != ERROR_SUCCESS)<br />
rfi->ShowError(rfi->serial.GetLastError(), _T("Unable to open COM-port"));<br />
<br />
lLastError = rfi->serial.Setup(CSerial::EBaud9600,CSerial::EData8,CSerial::EParNone,CSerial::EStop1);<br />
if (lLastError != ERROR_SUCCESS)<br />
rfi->ShowError(rfi->serial.GetLastError(), _T("Unable to set COM-port setting"));<br />
<br />
lLastError = rfi->serial.SetupHandshaking(CSerial::EHandshakeOff);<br />
if (lLastError != ERROR_SUCCESS)<br />
rfi->ShowError(rfi->serial.GetLastError(), _T("Unable to set COM-port handshaking"));<br />
<br />
lLastError = rfi->serial.SetMask(CSerial::EEventBreak |<br />
CSerial::EEventCTS |<br />
CSerial::EEventDSR |<br />
CSerial::EEventError |<br />
CSerial::EEventRing |<br />
CSerial::EEventRLSD |<br />
CSerial::EEventRecv);<br />
if (lLastError != ERROR_SUCCESS)<br />
rfi->ShowError(rfi->serial.GetLastError(), _T("Unable to set COM-port event mask"));<br />
<br />
lLastError = rfi->serial.SetupReadTimeouts(CSerial::EReadTimeoutNonblocking);<br />
if (lLastError != ERROR_SUCCESS)<br />
rfi->ShowError(rfi->serial.GetLastError(), _T("Unable to set COM-port read timeout."));<br />
<br />
HANDLE hevtOverlapped = ::CreateEvent(0,TRUE,FALSE,0);;<br />
if (hevtOverlapped == 0)<br />
rfi->ShowError(rfi->serial.GetLastError(), _T("Unable to create manual-reset event for overlapped I/O."));<br />
<br />
OVERLAPPED ov = {0};<br />
ov.hEvent = hevtOverlapped;<br />
<br />
HANDLE hevtStop = ::CreateEvent(0,TRUE,FALSE,_T("Overlapped_Stop_Event"));<br />
if (hevtStop == 0)<br />
rfi->ShowError(rfi->serial.GetLastError(), _T("Unable to create manual-reset event for stop event."));<br />
I am searching for a solution for some days now, and it would be really really great to get some help, at least getting a starting point where to look at.

You can write more than 16 Bytes, I think the setup of the port.
Or the endpoint of the RS232 (the HArdware) is only liking 16 Bytes.
Can you write in 16 Byte loopes? If not there is big trouble.

From germany? Nice, me too
No, the endpoint can handle more than 16 Bytes definetly.
I managed to write a total simple communication class which can write more than 16 Bytes. And I cant find the difference between them. I dont know where to search, and what to search for.

I believe you to change the Setup/Initialization of the Port. Compare every single value. There are some samples at CP try different to get it work.
Have you tried to write in loops???
//Meta-Code
while( DataToSend() )
{
Send16Bytes();
}
GetLastError() is also your friend!!!
Serial Port is a legacy problem so not so many know how to handle.
