If your doing any kind of port programming then your deffinatly going to want to check out the CSerial utility class.
http://www.codeproject.com/system/serial.asp
Its without a doubt, one kick ass class library. The sample includes C++ console, and mfc samples. Check it out pronto!

Hello Guru's
I am writing below code for copy the content of buffer to file
CString strLine = "";
CString buffer = "";
CStdioFile fileObj,filewrite;
CString fname;
fileObj.Open(str, CFile::modeRead | CFile::shareDenyWrite);
fname = fileObj.GetFileName();
while(fileObj.ReadString(strLine))
{
fileObj.ReadString(strLine);
buffer += strLine + "\r\n";
}
fileObj.Close();
// MessageBox(buffer);
SetDlgItemText(IDC_EDIT3,buffer);
/*//////////////////////Copying file to another folder//////////////////////////*/
fileObj.Open("c:\\UserFolder\\" + fname + ".txt",CFile::modeCreate,NULL);
///////////////////////////////////////////////////
filewrite.Open(str,CFile::modeCreate|CFile::modeWrite);
strLine.Empty();
while(filewrite.ReadString(strLine))
{
filewrite.WriteString(strLine);
fname += strLine + "\r\n";
}
filewrite.Close();
MessageBox(fname);
I am understand where i am wrong .
The above code work correctly up to
CString strLine = "";
CString buffer = "";
CStdioFile fileObj,filewrite;
CString fname;
fileObj.Open(str, CFile::modeRead | CFile::shareDenyWrite);
fname = fileObj.GetFileName();
while(fileObj.ReadString(strLine))
{
fileObj.ReadString(strLine);
buffer += strLine + "\r\n";
}
fileObj.Close();
// MessageBox(buffer);
SetDlgItemText(IDC_EDIT3,buffer);
/*//////////////////////Copying file to another folder//////////////////////////*/
fileObj.Open("c:\\UserFolder\\" + fname + ".txt",CFile::modeCreate,NULL);
and i can create an 0 byte .txt file using this .But when i try to copy content on buffer to file . I am become fail I think this code of line is wrong .
filewrite.Open(str,CFile::modeCreate|CFile::modeWrite);
strLine.Empty();
while(filewrite.ReadString(strLine))
{
filewrite.WriteString(strLine);
fname += strLine + "\r\n";
}
filewrite.Close();
MessageBox(fname);
if any one in the world tell me how can we solve this problem.

You open file on the write mode but in this loop you want to read of that?
filewrite.Open(str,CFile::modeCreate|CFile::modeWrite);
strLine.Empty();
while(filewrite.ReadString(strLine))
From the MSDN
CFile::modeRead Opens the file for reading only.
CFile::modeReadWrite Opens the file for reading and writing.
CFile::modeWrite Opens the file for writing only.

|
|
|
if i use the mode like
filewrite.Open(str,CFile::modeCreate | CFile::modeRead);
again it can not write file

|

in the read write mode
filewrite.Open(str,CFile::modeReadWrite);
it will return only name of file at last.(in messageBox)

Hi,
I think your are mistakenly using file objects.
The following seems reading from and writting to same file. and also
"filewrite" is created in write mode.
while(filewrite.ReadString(strLine))
{
filewrite.WriteString(strLine);
fname += strLine + "\r\n";
please review it.

I have used other databases, but not for Ms SQL server.
I think if connection and/or open SQL server databese is successful, rest should be similar to using other database.
is it correct?
Q:
how to connect and/or open SQL server databese?
any other important points?
please help with several steps if possible.
thx

it looks not too hard - similar to c++ for mysql, both use raw functions.
is there any existing MFC classes for SQL server? any samples?
thx.

Hello,
Anyone have ideas about invisitasking (http://www.diskeeper.com/defrag/InvisiTasking.asp) and how to do it in c++?
Is it some kind of machine learning techniques where the program study the habit of the users and then wait until a suitable time to perform a task or is it just wait for a situation when there is low CPU usage AND no input from the user AND etc..?

where is the memory leak / error in the output?
|
|
|
|
|
ohh
its not a leakage but this will happen while I am debugging my code and also while I am running my program.
This error is going to terminate my application in between the usage of the system.
So, please give me reply
|
|
|
|
|
But you started the thread as a memory leak problem.
The log you have posted doesnot give much information of your problem.
The debugging info only shows the symbol missing error, please refer Iain Clarke's description below.
If your app terminates due to huge memory usage, you have to find it out by reviewing your code (I prefer it), debug, detect using static or dynamic source code analysers like boundschecker, ....
|
|
|
|

Um, what memory leakage? You're just showing that Visual C++ can't find debugging symbols for system DLLs. This isn't a great shock. This just means that when you're debugging, if the call stack goes through a system DLL, you won;t know the function name.
If this is a real problem, go look at the recently posted article on setting up a symbol server (not sure if that will work with as old a compiler / debugger and 6.0. (I use 6.0, but I also don't use the symbol server)
Iain.

SystemParametersInfo with the SPI_SETDESKWALLPAPER flag set.
You can also do lots of other stuff with it... Check this MSDN link[^]
