In VC, Open Project->Project Settings->[Tab C/C++]
on that Tab, in Listing file type, choose Assembly with source code. This outputs the desired .asm file.
Hope this helps

How can I check for the version of Windows during installation of my application in a setup program using Launch Conditions Editor in the Setup Project of Visual Studio? What condition I should use and how?
Secondly, if my software is meant only for Win NT, 2000 and XP, can I safely afford to exclude InstMsiA.exe bootstrapper file in my setup files?
Thanks.

I am doing profiling on a program.When i am doing "function timing" and
"Function coverage" the result are properly present in the profile window and i can copy all the result into a file.But when i do "line profiling" all the result from the begining are not seen in the profile window.Can i save the result directly into a file(say notepad/wordpad) while the line profiling is going on.

Can I use the Setup Project provided with Visual Studio .NET for preparing Installation for my VC++ project?

when built my program in VC++ 6.0,I frequently receive a message box displaying "this file has been modified out of the source editor , do you want to reload it?" , and after this, I find that the file is indeed changed and in turn some errors occured, how can this happen?
afterwards, I find a clue for this error: the file being modified each time is the same file named "DetailedDesign.h". and the file is changed typically when I make a call to "rebuild all".
so I tried setting the file "read only",and when I call "rebuild all", one error occured, following are all of the generated informations:
Deleting intermediate files and output files for project 'DetailedDesign - Win32 Debug'.
Error: Could not delete file "E:\my project

What have you chosen as output directory for your Debug session ? Is it E:\my project\DetailedDesign\ ?
Where is this file located in your Source Browser ?
Is this file somehow auto-generated ?
~RaGE();

all of my source files including the "DetailedDesign.h" are in the dirctory "E:\my project\DetailedDesign\", and the Debug output directory is " E:\my project\DetailedDesign\Debug" as default

Can any one help me to find data encoding of received buffer with WSARecv() command.
Weather data send by client is in UNICODE or in ASCII format
E.g.:
WSARecv (AcceptSocket, &DataBuf, 1, &RecvBytes, &Flags, &AcceptOverlapped, NULL)
DataBuf.buff is in ASCII or in UNICODE
Regads,

Using VC++.NET2003
I have written serial routines (ported from Apollo) as follows:
but I am finding that with a serial loopback setup
the leading bit is reset on all chars (ie. transmit 0xff and receive only 0x7f)
I have a feeling its to do with binary vs text mode but I am unable to resolve.
Code:
CSerial::CSerial (LPCTSTR pszCommPort, LPCTSTR pszMode , char LineTerminator)
{
m_strCommsPort = pszCommPort;
m_strMode = pszMode;
m_LineTerminator = LineTerminator;
}
CSerial::~CSerial ()

ios_$close();
}
void CSerial::ios_$close(void)

if ( m_Port != INVALID_HANDLE_VALUE )

GetLastError(), MAKELANGID(LANG_NEUTRAL,
SUBLANG_DEFAULT),szBuffer, sizeof szBuffer, NULL );
strcat ( szBuffer, " opening " );
strcat ( szBuffer, m_strCommsPort );

return false;
}

dcb.DCBlength = sizeof DCB;
GetCommState(m_Port, &dcb );
BuildCommDCB(m_strMode, & dcb);

// Maximum time between read chars.

// Constant in milliseconds.
lpCommTimeouts.ReadTotalTimeoutConstant =0;
// Multiplier of characters.

// Constant in milliseconds.
lpCommTimeouts.WriteTotalTimeoutConstant = 1000;
SetCommTimeouts(m_Port, pPortTimeouts);

int iCode;
DWORD bytesRead;
LPDWORD pBytesRead = &bytesRead;
iCode = ReadFile ( m_Port, (unsigned char *)cbyte,
1,pBytesRead, NULL);
if (bytesRead == 0)
{
return 0;
iError = GetLastError();

else

I haven't looked closely at the rest of the code, but try adding
to the device control block configuration to make sure the UART isn't defaulting to 7 bit mode.

HI, I have found the error is not the software but the edgeport/4S USB serial port hardware I am using. I tested the software on a direct RS232 port and it worked correctly. I have since found that re-installing the edgport/4s 4 port unit and then re-instating RS422 has fixed the problem.

Hi all !!
I practise VC. When I code my program to create a file.
The first time when I click my button2 (create file) I receive a error "access pathdir to file is denied" but I can create file at the second click. I don't know why ??? Please,I need help !!
This's my code when click button2, I use MFC wizard (use dialogbase)
void CTestDlg::OnButton2()
{
// TODO: Add your control notification handler code here
char filename[100];
GetCurrentDirectory(100,filename);
strcat(filename,"\\RongVang.dat");
CFile f;
if(!f.Open(filename,CFile::modeReadWrite))
f.Open(filename,CFile::modeCreate);
f.SeekToEnd();
char s[100];
strcpy(s,"Test Create file");
f.Write(s,100);
}

the filename return format is not like this"C:\\ adir"
it return format is "C:\adir"
it can't use as a parameter in F.Open Function .

Thank so much !!
But how can i slove it ....
Can you show me .....
I've just program...
|
|
|
|

Why do you open the file two times?
i think there you get the error.
if(!f.Open(filename,CFile::modeReadWrite))<br />
f.Open(filename,CFile::modeCreate);<br />
Try this:
if(!f.Open(filename,CFile::modeCreate | CFile::modeReadWrite))
|
|
|
|
|
if(!f.Open(filename,CFile::modeCreate | CFile::modeReadWrite)) f.Open(filename,CFile::modeCreate);
The first click it will create file.
I want at the second click, third,4,5,.... click in button2, it will append my file, not delete and create new file like above !!
Can you help me ... !!!!!!!!!!!!
|
|
|
|
|
CString filename = _T("C:\\RongVang.txt");<br />
CStdioFile f;<br />
if(!f.Open(filename,CFile::modeReadWrite))<br />
f.Open(filename,CFile::modeCreate|CFile::modeReadWrite);<br />
f.SeekToEnd();<br />
CString s = _T("Test Create file\n");<br />
f.WriteString(s);<br />
dont forget to close your file.

Then use:
if (f.Open(filename, CFile::modeCreate | CFile::modeReadWrite | CFile::modeNoTruncate) != FALSE)
{
f.SeekToEnd();
...
