Not sure what version of VS you are using, but the file handing classes in the MFC (CFile etc) were updated to handle large file sizes. So the CFile::GetPosition() now returns a ULONGLONG, Seek() has a LONGLONG parameter...and so forth.
I now about the file limitation for VS6, but for the MFC 7.0 (VS7.1), these were updated.

you may use CreateFileMapping and ViewMapOfFile to map such files into your process address,__int64 will be ok.
DWORD dwFileLo = ::GetFileSize(hFile,dwFileHi);
ASSERT(dwFileLo != INVALID_FILE_SIZE);
__int64 qwFileSize = dwFileHi << 32 | (dwFileLo & 0XFFFFFFFF);
Later buggers harm more.

Dude! Information overflow!!
Condense your code sample and ask again, else I doubt anyone would consider wading through all of that.

I'm all curious now what his second question was.
I know the first was... "Here's 500 lines of my code, not even using the pre tag. What's wrong with it?".

How to programmatically make the dotted-line rectangle show on the focused button when a dialog based application is just launched? Thanks!
In VC++6, the dotted-line rectangle displays automatically for dialog based applications. But latter versions of Visual C++ do not unless user press the ALT key.

Erm, I'm pretty sure this is an OS settings. You haven't upgraded your PC too..?

If you look up SystemParametersInfo and SPI_GETKEYBOARDCUES, they're the parameters that govern whether keyboard shortcuts show up.
But you're more interested in the focus rectangle on a dialog... I'm assuming that's related. But if not, just make sure you have a tab stop order set appropriately, and that your buttons have the WS_TABSTOP set. Beyond that, I have no idea...

Yes, tab order of the button is set, and WS_TABSTOP is set for the button (therefore when ATL is pressed the rectangle show up on that button).

And I added the below in MyDlg::OnInitDialog(), but I don't even see the menu-access key underlined... (unless ALT is pressed)
SystemParametersInfo(SPI_SETKEYBOADRCUES, TRUE, NULL, 0);
(Weird?! It does not allow copy and paste when editing this post? )

Doesn't it have to be...
BOOL bOn = TRUE;
SystemParametersInfo(SPI_SETKEYBOADRCUES, 0, &bOn, 0);
?

Oh I made a mistake. This solution works! Thanks.

Not in my machine. In both vc6 and vc8 I checked, for displaying the focus rectangle, either you have to press tab or ALT key.

A difference between the apllicaton created in vc6 and later are, by default the applications will be using version 5 of comctl32.dll, where as in later version of vc, it will be using version 6 of comctl32.dll ( that y u get the XP look and feel for the application created in vc7 or vc8 ).

You are right! I doublechecked again with VC6, and it does not under WinXP. (It might be in Win2K / WinNT4 time ...)

Are you looking for DrawFocusRect()?

Finally I realized that to return FALSE in OnInitDialog solves it, too.

Just looking for a point in the right direction. I need to enumerate the existing network connections (like those listed in "Connect To"...
Would like to be able to determine which is active and other characteristics of the connection, including the underlying device...
Where should I look? (I hope it's not WMI)

Hi all,
Say I want to find the number of characters in a string. In simple way, get the length of the string and then count the numbers of space, tabs and the difference gives the number of characters. Here is a simple code.
int iSpace = 0;
int iRet = 0;
int iTabs = 0;
int iLength;
string strString("One Two Three ");
iLength = strString.length();
for(int i = 0; i<ilength;i++)>
{
if(strString.at(i) == ' ')
{
iSpace ++;
}
if(strString.at(i) == '\t')
{
iTabs ++;
}
if(strString.at(i) == '\r')
{
iRet ++;
}
}
cout << (iLength - (iSpace + iTabs + iRet));
cout << endl;
<pre>
Should I do anything more on this to make more reliable the result. :-D
I appreciate your help all the time...

The character classification functions may help you
MSDN link[^]
they let you do things like:
char c;<br />
..<br />
if (isspace(c)) {}<br />
<br />
if (isalnum(c)) {}<br />
<br />
etc

Where did you find the newline character there.
