Make this question in a Symbian forum, like www.newlc.com. By the way, it is not a good idea (and not very polite too) to keep crucial information hidden from the people you are asking to help you.

Hello all, I recently compiled a release build of a project and ran into initial problems that would cause the application to fail. After correcting these problems (program appears to function properly w/ no crashes), I decided to send it to some friends to test out. On the first attempt, my friend reported he receive a msg asking for MSVCPP70. Thinking that this might be a MFC dll issue i went into my project settings and set the option to use mfc in a static library. After doing this, my program will run, except for a feature which communicates w/ a server via a worker thread. The odd thing is... the application runs flawlessly on my own system.
What issues do you think I am running into? Are there dlls that i should be coupling w/ my release build?

It's hard to say from the info you provide...

So, what happens with that feature? Does it give some error (which)?

Sounds more like a firewall/network problem to me. Where is the server located? Is it accesible from your friend's PC?

Hi,
I got error code 10013 for the follow fuction. But I can't fix the problem, some body help , please!!!
if(WSCInstallProvider( &filterguid, (unsigned short *)filter_path, &iplayerinfo, 1, &errorcode) == SOCKET_ERROR)
{
AfxMessageBox( "WSCInstallProvider Error : " + itos( errorcode ) );
return;
}

Just in case you haven't already read it, the following is from the documentation of Windows Sockets Error Codes[^] in MSDN:
WSAEACCES
10013
Permission denied.
An attempt was made to access a socket in a way forbidden by its access permissions. An example is using a broadcast address for sendto without broadcast permission being set using setsockopt(SO_BROADCAST).
Another possible reason for the WSAEACCES error is that when the bind function is called (on Windows NT 4 SP4 or later), another application, service, or kernel mode driver is bound to the same address with exclusive access. Such exclusive access is a new feature of Windows NT 4 SP4 and later, and is implemented by using the SO_EXCLUSIVEADDRUSE option.
See also: Windows Sockets Network Programming - Appendix C: Error Reference[^]
Hope that helps,

Besides, what's the type of filter_path? Why do you need a cast to (unsigned short*)?
Hint: if filter_path is a char*, as I suspect, simply casting to (unsigned short*) won't work.

how can I make this work right?

Hi Spirit,
First id like to declare that Ive never used the functions that you're using
in this code snippet but here's my two bobs worth.
1) It looks like MapViewOfFile is returning NULL (which it does in case of error). (so pDosHeader->e_lfanew evaluates to 0x3c... sounds feasible?)
2) Reading to doco it looks like the "dwDesiredAccess" flag isnt "addable"
(Ths do saye "This parameter can be one of the following values").
It also says that FILE_MAP_WRITE by iself gives RW access.
Try playing with the MapViewOfFile args and check the returned value for NULL maybe
Cheers

Maybe because in MapViewOfFile you left the last parameter at 0 (dwNumberOfBytesToMap) instead of setting it to size of file?

I’m trying to use a list box control in a windows app I’m writing. I put on the control on my dialog resource, I assign it a member variable: as a control, CListBox. But in my code, when I try to use the function AddString (i.e. dlg.m_variableName.AddString(“Some Letters”) ) I get a debug assertion failure. Maybe I’m missing a step here? Is there more initialization I have to do?
I don’t really need the selectability of a list box. I tried just making it an edit box with a scroll bar, but I can’t get each item on a new line.

where does the assert happen ?
The simple answer? Somewhere in the AddString method.
The more complicated answer? The debug pop up tells me the assertion failed at afxwin2.inl at line 669.

_AFXWIN_INLINE int CListBox::AddString(LPCTSTR lpszItem)
{ ASSERT(::IsWindow(m_hWnd)); return (int)::SendMessage(m_hWnd, LB_ADDSTRING, 0, (LPARAM)lpszItem); }
it's failing because the CListBox isn't a window (yet). i'm guessing you're calling AddString before the dialog has had a chance to create the list box and/or associate it with your member variable.
put a breakpoint on your AddString and one in your dialog's OnInitDialog. if the AddString breakpoint hits first, you need to move it to after the dialog has been initialized.

Alternatively, the release version works, or rather, survives. It works with the exception of the text that I wanted to put in the list box is not there.

The debug version ASSERTs because the window hasn't been created yet. In the release version, the ASSERT doesn't fire, and the SendMessage call silently fails. In this case, the control eventually gets created, but the string you're looking for isn't there due to the earlier SendMessage failure.

Make sure you are doing this in the dialog's OnInitDialog() method, after the default method has been called.

Im trying to read a large text file with a CStdioFile object (the file's around 2.3 Gb, OS Windows XP, File System NTFS).
After reading for a while an exception is thrown during a CStdioFile::ReadString call which says something like "Controler Invalid"
I simplified the code so that its doing nothing more than loopìng around the ReadString call, and the error persists.
Could there be an inherent limit on the size of a file readable using CStdioFile (I dont belive that 2.3 Gb is too big for NTFS ?!?)
Thanks,
Dave

You may be running into some unexpected 32bit dword limitations, not necessarily a file os problem, but a file pointer limitation.
|
|
|
|
|
That sounds something like whats happening, but does anybody know of any settable limmitations of this type that exist?
|
|

Are you using VC6? if so then the file pointer used is a 32 bit value, with a limit of 2GB. AFAIK if you are using VC7+ then the file pointer is a 64 bit value.
If you want to get around this limit in VC6 then do not use the MFC classes (which wrap the fopen, fread, etc CRT functions) and use the SDK functions CreateFile, ReadFile etc.

Yes thats it PJ!
I am using VC6.
(I guess its time to shell out for an upgrade!)
Thanks so much for the help

Seriously? I always though that MFC didn't wrap CRT functions, but rather the WIN API directly! The CRT file API's (I don't know about the others) are just a layer on top of the OS's API's, which are CreateFile, ReadFile, etc..
I don't know about the MFC shipped with VC6, but the newer MFC version 8, does wrap the window's API's...
