Hi,
Are there any good window installers for installing VC++ 6.0 software,
(should be cheaper than InstallShield) ?
Thanks

Try with download.com. search installer.
By the way you can download a better software
1) "Install Creator".
It is a free software and cheap to use.
2)"Install us"

Try Thundersetup from CMware:

I use Inno Setup 4. http://www.jrsoftware.org/isinfo.php
It's free and you can edit it. It is nothing more than a script compiler but comes with a setup wizard.

is it possible to run an raw file using c or c++ program

raw files ? what does the raw file contain?

i am talking about .raw audio file playing thru c or c++ program

The data comprising the program must first be saved to disk. At that point, you can employ CreateProcess() or ShellExecute() to run the program.

Are you talking about playing .raw audio files?
AFAICR, this is raw signed PCM format, with no header. If you google on
.raw and audio you might find something to help with constructing a header so you can play the sound. You'd have to use relatively low level multi-media API calls, though.

I want to exact installation root of my MFC application as a CString format.
Like str="D:\Program Files\Test\test.exe"
How can i do it? Or how can i can find root of my MFC EXE program.

CString tmp;
TCHAR* ptr = tmp.GetBuffer(_MAX_PATH);
::GetModuleFileName(AfxGetApp()->m_hInstance, ptr, _MAX_PATH);
tmp.ReleaseBuffer();
should do it.

Hello.
well i just want to ask if anyone of you knows the implementation of solving system of linear equations by using Gauss-Jordan elimination method ( or known as reduced row echelon form ) since i need some help for my assignment.
best regards.

You can find the implementation of solving a linear equation pair with the Gauss-Jordan method from this page: http://www.sks99.com/ch9/gauss/defg.htm
As for the actual implementation, take a piece of paper, and write down all the intermediate calculations, then take a moment to consider how you could represent it in the C/C++ -environment. For example, if you create a program that asks as an input on the equations, or more easily, their coefficients, you can instantly write a matrix. Then follow the implementation guide, and perform similar operations on the computer matrix, as you would into a real matrix.
Remember, that computer matrixes and real matrixes tend to handle direct operations differently. Consider writing a set of functions that allows you to do matrix addition, difference, multiplication and division operations. Do not do a direct addition, as it might lead into wrong results.
As this is an assignment, I cannot give you direct code, but I can help you on by saying that a number matrix in C++ can be represented by a declaration such as int matrix_1[col][row]. Use this as a base in creating the coefficient matrixes, then just do the same calculations as the page I posted earlier. Dynamic arrays cannot be used, so you either need to create a big matrix then designate by a number of how many rows/cols are valid, or leap over to the STL routines, from which I have no experience.

There are a lot of linear algebra C++ libraries, for example BLAS. Try google "linear algebra c++ library".

I have an MFC dialog which is built over a layout-engine.
This dialog also contains many owner-drawn controls.
When you popup the app and start resizing it quickly, everything looks good, responds fast, cleans-up, no window trails.
After 3-4 seconds of quick-resizing, the application begins to stall and leave-trails on the screen.
I've been trying to disable things to try and find out whay may eb causing this sudden performance-degrading... but to no avail.
Perhaps this could be a bad case of no releasing DCs ? or some other male-functioning with Graphic Objects ?
Does anybody have an idea ?

Hi dear gurus. I am using CListCtrl in Report view, and there is one thing I'd like to try out. Is it possible to enter multiple lines of text into one single cell? I mean, if the length of the text exceeds the length of the row it gets truncated and appended with "..." or the List Control gives you a hori scroll bar to play around with.
What i am thinking about is making the word appear in the next line, but stay in the same row...
Visual example
(without word wrap)
-------------------------------
| I got too much crap in my...|
-------------------------------
| Something else |
-------------------------------
(with word wrap)
-------------------------------
| I got too much crap in my |
| brains and I don't know |
| wat to do with it. |
-------------------------------
| Something else |

Can this be done? Do i need to override the DrawItem fucntion?

Hi~ all. 
I'm in the middle of writting a simple serial comm app but there's a Question I can't understand.
In my code, just simple data communication is OK. But when I wanna make more fast data exchange in short that make a little problem. Two program A, B can communicate well with a simple line, but to make fast and recursive data communication I made a thread that writes a data line to serial port. (Thread function In B that write 8 bytes string data expecting 14 bytes reply.) If time delay between two *sending* data string is long ( 3 secs ) send and reply is OK. However if I make the delay to be short ( 2 or 1 sec ) A works all right, and B doesn't. B cannot read any data.
Between A, B there's no difference except B has a recursive writing function in thread. So I wander whether writeing to port makes a effect to reading from that one or not.
Anybody can tell me a good solution?
Sorry for my poor English.
And Thanks in advance.

I have not done serial communication programming so i dont know the exact solution but here is a lead.
You cant wirte to the port as and when you want it. before writeing you need to cheack the port status wheather it is ready to send any data, then you should write any data to the port.
Using the method you can avoid the unwanted delay(sleep) in ur code.

Thanks.
But the delay I mean is my own setting one with Sleep(); and checked port status, too.
End of this, I'll include the code used. If I use 'Sleep(3000)' in thread function(StartThread) communication is looked OK. But if I use 'Sleep(1000)', communication is to be broken. B cant receive any data just because of shortened Sleep() time. Two programm A, B use normal serial communication routine, and B has one more thread function as following.
In StartThread 'm_Port' is CSerial Class obejct.
Again, Thanks a lot anyway. 
UINT CNewParkDlg::StartThread(LPVOID param)
{
THREADSTRUCT* ts = (THREADSTRUCT*)param;
CString strPoll;
strPoll = (CString)STX + "N1PL" + (CString)ETX + "60";
int nSize = strPoll.GetLength();
while(true) {
// Display to ListBox
ts->_this->m_pListBox.InsertItem(0, strPoll);
ts->_this->m_pListBox.SetItemText(0, 1, "Send");
ts->_this->m_Port.WriteComm((BYTE*)(LPCTSTR)strPoll, nSize);
// Sleep(1000);
Sleep(3000);
}
return true;
}
typedef struct THREADSTRUCT {
CNewParkDlg* _this;
} THREADSTRUCT;
DWORD CSerialPort::WriteComm(BYTE *pBuff, DWORD nToWrite)
{
DWORD dwWritten, dwError, dwErrorFlags;
COMSTAT comstat;
int n;
n = WriteFile(m_hComm, pBuff, nToWrite, &dwWritten, &m_ovrWrite);
if (!n) {
if (GetLastError() == ERROR_IO_PENDING ) {
while ( !GetOverlappedResult(m_hComm, &m_ovrWrite, &dwWritten, TRUE) ) {
dwError = GetLastError();
if (dwError != ERROR_IO_INCOMPLETE ) {
ClearCommError(m_hComm, &dwErrorFlags, &comstat);
break;
}
}
}
else {
dwWritten = 0;
ClearCommError(m_hComm, &dwErrorFlags, &comstat);
}
}
return dwWritten;
}

In ITU, it needs money to order the jpeg specification! So, do you know where
can I get the jpeg specification??
If you know or you have these specification? Please let me know!
