It would help it you told us what "C++BuilderX" is. Presonaly, I have never heard of it.

i don't what the Mobile App sample is supposed to be, but if it uses MFC or Microsoft specific classes, you cannot compile with a compiler that don't have the source of the libraries...

i don't know how C++BuilderX works, so a cannot tell you wht these eror messages refer to... see the doc of you compiler/linker (maybe) for that.

Release build doesnt function completely on other systems

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,

change entry point address

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.

this:

<br />
 pNtHeader = (PIMAGE_NT_HEADERS)((DWORD)pDosHeader + (DWORD)pDosHeader->e_lfanew);<br />

makes an error like this:

Unhandled exception at 0x00411b52 in pan.exe: 0xC0000005: Access violation reading location 0x0000003c.

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?

Dialog List Problem

bugDanny31-Aug-05 7:54

31-Aug-05 7:54

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.

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.
