if using MFC appwizard
make a control variable for the edit control using the class wizard in the member variables tab
again, in class wizard, but this time in message maps tab, find the object ID (IDC_EDIT etc) used for your control in the object ID list, and on the right, click the "EN_CHANGE" message, then click "Add function" it will probably default name it to xxxOnChange()
find this xxxOnChange() function in your dialog code, and then count the characters in the edit box using GetWindowTextLength()

Hi Im writing an Addin for MS Outlook 2003 on VC++ .Net 2005. Actually I want acquire the handle of every new in coming Message/Mail from Exchange
server to MS Outlook Mail box. For that I am using Project type as New/Project/Other Project Types/Extensibity/Shared Add-in with ATL and
COM support. Until what i know is that every message contains it unique ID which is received from the Exchange Server. I want to get the message
pointer and using that I want to get the Message ID either in the Queue or Vector and then perform some specific task related to it.
So please can anyone tell what i can do for solveing this problem?.
Cheers
Ganesh

Hi, all
In the program given below i am supposed to read a file irrespective of the size of the buffer.
->i am not able to implement the reading of the file character by character
and then mention the EOF.
->how am i supposed to dot that??? what are the necessary changes required?
void CReadDlg::OnRead()
{
char szFilters[]="MyType Files (*.txt)|*.txt|All Files (*.*)|*.*||";
CFileDialog fileDlg (true,"txt", "*.txt",OFN_FILEMUSTEXIST| OFN_HIDEREADONLY, szFilters, this);
fileDlg.DoModal();
// TODO: Add your control notification handler code here
UpdateData( TRUE );
HANDLE hFile;
DWORD dwBufSize=BUFSIZE;
BOOL bRet;
DWORD dwBytesRead;
char buffer[BUFSIZE] = {0};
hFile = CreateFile(fileDlg.GetPathName(),
GENERIC_READ,
FILE_SHARE_READ,
NULL,
OPEN_EXISTING,
FILE_ATTRIBUTE_NORMAL,
NULL);
bRet = ReadFile(hFile,
buffer,
BUFSIZE,
&dwBytesRead,
NULL);
/* while (!_eof(int fd))
{
buffer = */
m_ed = fileDlg.GetPathName();
m_text_ctrl.SetWindowText(buffer);
m_text_str = buffer;
UpdateData(false);
}

Check the return value from ReadFile() and the value of dwBytesRead to determine when EOF has been reached. GetLastError() may also return ERROR_HANDLE_EOF.

i have tried that it didnt work for me, perhaps im calling it in the wrong place ??
STARTUPINFO siStartupInfo;
PROCESS_INFORMATION piProcessInfo;
siStartupInfo.wShowWindow = SW_HIDE;
memset(&siStartupInfo, 0, sizeof(siStartupInfo));
memset(&piProcessInfo, 0, sizeof(piProcessInfo));
siStartupInfo.cb = sizeof(siStartupInfo);
if(CreateProcess......
any ideas ??

You should call this before assigning values to structure.

i have tried placing
siStartupInfo.wShowWindow = SW_HIDE;
before and after that, but still the same

You need to use StartUpInfo.dwFlags to make it effective,
StartUpInfo.dwFlags = STARTF_USESHOWWINDOW;
StartUpInfo.wShowWindow = SW_HIDE;

Why use Initialize before memset

Hi all,
I need to be parse the XML file. So, please send any light weight XML parser library in Visual studio 2005.
Already I have been tried one XML parser. But there is some memory problem would arrive whenever run my application. The name of that one is "Apache's Xerces C++ Parser" by Fengjun Lv.
Thanks in advance

CMarkup [^] in an alternative to the TinyXML mentioned above.
The memory problem with Xerces is in your code?
Or are you working on a very small (128K RAM) machine?

Hi jhwurmbach,
Now my machine has 256MB ram.I think problem should be from my code.
1. My application is some times work properly that is only when i rebuild my application and then run my application, Xerces gives a correct solution.
2. But,when i compile my App.. and then run my App.., only one or two value of attributes would be displayed,then "can't read memory location 77oxx8...Reading voilation.." will be displayed.
what is problem actually...

In what function are you in at that time? Yours, or a Xerces function?
What is the last entry of the call stack you are recognizing as your code?
Very probably the error is there or a few steps "upstream".
You are not using delete on the pointers you get? You are correctly using release() as written here[^]?

Hi,
Now i am following below link,
http://vipbase.net/xmlparser/[^]
There is give one example XML file, i can't get result even given example file. the same problem would arrive....
|

OK. You've even got a tutorial there. Maybe there is a problem with the Xerces Parser? Which VC++ version are you using?
Or maybe the XMLparser code is wrong?

Currently i'm using visual studio 8.
XercesParser giving good result, but sometimes it has been give the same error. Can you see that the XmlParser.cpp file, there is didn't delete the CXMLParser object in parese function.It's OK tell me your opinion.

With a XMLParser designed for VC6? Recommending a Xerces dating from 2003?
Hmm.
OK, I got the source here, but its not running due to the ancient old Xerces wanting some stuff from VC6.
Even the CXMLParser-part did not compile, as the author relied on VC6 deviations from the standard.
surezu wrote: Can you see that the XmlParser.cpp file, there is didn't delete the CXMLParser object in parese function.It's OK tell me your opinion.
Thats OK, because in the destructor of CXMLParser, first the Xerces parser member mParser is deleted, and subsequently XMLPlatformUtils::Terminate();
is called. Xerces is correctly shut down.
What exactly is going wrong?

yah, some times it's bring good results when i run my application at first time but after that it will bring error ie.
1) "The instruction at "0x7c93..." referenced memory at "0x000000..". The memory couldnot be read.
2) The exeception unknown software exception (0xc0...)occured in the application at location 0x7c....

Where? Where in your Code?
I am asking this for the third time now!
You really need do debug your application and post the results!
Somewhere, somehow, there is a NULL-Pointer dereferenced.
Failure is not an option - it's built right in.
