The extension doesn't matter. I can rename the file to whatever I want, and it shows the same chinese signs. Anyway, I think I've figured out why this happens how. Then the WinXP parses a file it tries to find out if it's ASCII or Unicode.
An experiment:
- Create a new .txt file in Notepad, enter "Sprudling", and save it as usual.
- Open the file in an hexeditor and insert 2 bytes in front og "Sprudling".
- Set the 2 bytes to FFFE, and save the file again.
- Now open it again in Notepad.
It's now shown in unicode as "灓畲汤湩", which is 4 chinese letters for those who actually have installed those letters. I guess Notepad is more than you thought... :]

Probably what is happening is that Notepad is using an auto-detect to see what encoding you are using. With those binary characters at the start, it is getting fooled into thinking it is something like UTF-16 (or whatever they call UNICODE).

I seriously doubt that Notepad does anything of that sort. It's only functionality is to open the file and read the contents into a multi line edit control.

BZZZZZ....
Wrong.
Save something from Notepad. On the save dialog you get to select the encoding. Now, since there is no magical encoding flag in the file system, that information has to be stored in the file.
When you open a file in notepad, it goes through some nasty work to try figure out the encoding. For example, UTF-16 can commonly be detected by looking for alternating 0 bytes.

Oh Boy!!!
Thanks Tim S. Thanks for the info.
But this is bad. This means notepad is not a pure text editor anymore. Now what do we do? Windows comes with not a single pure text editor.
Do we all have to go back to the COPY CON days???

You could always use edit.com

edit.com was introduced with DOS 5.0 [it was part of the qbasic set]
later it became stand-alone

You can use IsTextUnicode and see what it returns. This is probably what notepad does..

According to the Microsoft "What's New In MFC7" information (that I've seen some time ago on the net), it is possible to enable standard Windows/MFC application to consume Web Services. Has somebody seen any sample/code or detailed technical article about the topic? Thanks.

I have a service that appears to eat memory at a pretty steady rate. If I bring up Task Manager, I can watch the Virtual Memory (and real memory) counter climb steadily.
In trying to solve the problem I used the CRT library to checkpoint the memory periodically. This technique has allowed me to find and fix several leaks.
Now, however, the CRT library machines are telling me there are no more leaks, while the task manager says there are still some left (real and VM still rises steadily). Following the example in MSDN, I've declared 3 _CrtMemState variables as globals (s1, s2, s3).
My app does a check point into s1 and then sets a timer.
When the timer goes off, the handler executes and then does another checkpoint into s2. The two checkpoints are compared into s3 and the result reported, as usual. The report shows differences in allocated memory between s1 and s2, as you would expect. The interesting part is that none of the allocation numbers change, while the Task manager keeps saying I'm eating memory!!
I know the checkpointing is working because the display shows a higher total allocations count each time.
Any ideas would be appreciated.
Here's the code I'm using for the checkpoints.
_CrtMemState s1, s2, s3;
_CrtMemCheckpoint(&s1);
::SetTimer(NULL, NULL, 1, OnPollTimer );
VOID CALLBACK OnPollTimer( HWND hwnd, UINT uMsg, UINT idEvent, DWORD dwTime )
{
AFX_MANAGE_STATE(AfxGetStaticModuleState( ));
_Module.m_bProcessRunning = TRUE;
::KillTimer(hwnd, idEvent);
DoPollTimer();
TRACE0(_T("OnPollTimer 1\r\n"));
_CrtMemCheckpoint(&s2);
_CrtMemDifference(&s3, &s1, &s2);
_CrtMemDumpStatistics(&s3);
TRACE0("----------------------------------------------------------\r\n");
::SetTimer(NULL, NULL, g_lPollFreqSecs * SECOND, OnPollTimer );
_Module.m_bProcessRunning = FALSE;
}
I don't have access to the server right now, so I can't provide a sample of the output. It shows some memory allocated as normal, client and CRT. The numbers don't change from one iteration to the next.
Any ideas would be greatly appreciated.
Thanks for the help,
Bill

(Some of my information might be outdated...)
Those routines can only check for memory managed by the C runtime library (this is where I could be wrong if they have changed how this works.)
Thus, things like ATOMs, heap allocations, native WIN32 allocations, etc can all still be leaking. Are you creating a bunch of GDI objects and not properly destroying them?

My app is a service running on NT. It has no UI, so I don't think its a GDI leak. Do you have any suggestions on how to detect/isolate the other possiblities for leaks?
I don't know how to monitor the rest of the memory usage.
Thanks for the help,
Bill

InsertItem don't work :
void CMyListView::OnInitialUpdate()
{
CListView::OnInitialUpdate();
ModifyStyle(NULL, LVS_REPORT,0);
// this code only works for a report-mode list view
//ASSERT(GetStyle() & LVS_REPORT);
// Gain a reference to the list control itself
CListCtrl& theCtrl = GetListCtrl();
// Insert a column. This override is the most convenient.
theCtrl.InsertColumn(0, _T("Names"), LVCFMT_CENTER);
// The other InsertColumn() override requires an initialized
// LVCOLUMN structure.
LVCOLUMN col;
col.mask = LVCF_FMT | LVCF_TEXT;
col.pszText = _T("Version");
col.fmt = LVCFMT_CENTER;
theCtrl.InsertColumn(1, &col);
theCtrl.InsertColumn(2,"Description",LVCFMT_CENTER);
// Set reasonable widths for our columns
theCtrl.SetColumnWidth(0, 200);
theCtrl.SetColumnWidth(1, 100);
theCtrl.SetColumnWidth(2, 100);
GetListCtrl().InsertItem(0, "First row"); //Don't work ??
// TODO: You may populate your ListView with items by directly
//accessing
// its list control through a call to GetListCtrl().
}
Please Help Me ,thanks

That's your problem. You need to turn off all the view styles (icon, large icon, list, report) as well as turning on the report style. (Also, NULL is not a window style.) Change it to:
ModifyStyle ( LVS_TYPEMASK, LVS_REPORT, 0 );

PostQuitMessage() and PostMessage(WM_QUIT,...) do not seem to work in WinCE PocketPC. I have an MFC WinCE app that uses CreateProcess() and WaintSingleObject() to create another MFC process. When the created process exits, I need to capture its exit code. I use GetExitCodeProcess() to do that. GetExitCodeProcess() always provides an exit status of 0. If the created process is just a simple Win32 WCE app, the exit code is correct.
Any hints ? Is there something I'm missing?
Thanks for any responses.

GetExitCodeProcess() always provides an exit status of 0. If the created process is just a simple Win32 WCE app, the exit code is correct.
So, what's your complaint? I don't get what's your problem here.

I'm having the exact same problem....try as I might, I cannot get my CE application to provide a non-zero exit code. Did you find the solution for this problem?

No I did not. Instead, I have the application what was spawned create a file if it successfully terminates. Then I check for the existance (or absence) of this file to determine the program's status.

I was afraid of that. I was considering the same approach, but wanted to avoid it. I hate having files sitting around on a computer.

Hi
I am looking for help in writing a parsing / data mine function to extract information from a message received from a windows socket. An example of the message is
SLF {name cakjl} {Location 123, 123, 321} Rotation {0, 0, 0}
Where I want to extract the three number in the Location part of the message and place them in a
struct { int x, int y, int, z} etc...
I am converting the buffer to a large string and matching the letters SLF, but am wondering how to extract the numbers?? I also need to do this for other types of messages and am trying to come up with a generic way of extracting the information and formatting it so I can use it.
Any help would be greatly appreciated
Thanks
Martin

A fairly general approach is using regular expressions for doing the parsing. If you're into hardcore C++, check John Maddock's Boost Regex++ library.
