You can ready any file as long as you know its format. Why do you want to read the file directly when Excel Automaton is much easier, and less prone to error(s)?

I want to initialize my static variables to maximum of the value of float, for which i defined:
<br />
const double LogMath::FloatMin = numeric_limits<float>::min( );<br />
const double LogMath::FloatMax = numeric_limits<float>::min( );<br />
const float LogMath::LogMax = log(FloatMax);<br />
const float LogMath::LogMin = log(FloatMin);<br />
in my cpp file (vs.net 2003). On doing so i get weird (?) errors as below:
<br />
error C2589: '(' : illegal token on right side of '::'<br />
error C2059: syntax error : '::'<br />
error C2059: syntax error : ')'<br />
error C2059: syntax error : ')'<br />
Using numeric_limits<float>::min() or numeric_limits<float>::max() in a seperate test exe didnt give any errors.....
Whats happening? Please help.

This is managed C++ no ? So post in the correct forum[^]

No, it is standard C++. He is fine where he is at.

Have you tried:
const double LogMath::FloatMin = std::numeric_limits<double>::min( );
const double LogMath::FloatMax = std::numeric_limits<double>::min( );

That is what i was doin at first.....
I ended up wrinting the values of min and max of float as
<br />
const double LogMath::FloatMin = 1.17549e-038;<br />
const double LogMath::FloatMax = 3.40282e+038; <br />
But would still love to know what was going on......
And thanks for replyin

numeric_limits is a member of the std namespace. So, unless you have a using namespace std; or using std::numeric_limits; line somewhere, you have to specify the namespace.
Additionally, numeric_limits is a template that needs the type specified. If you don't include the numeric_limits<double> part, the compiler doesn't recognize it as a type (because it isn't).

modify first line as 2 lines:
const double LogMath::FloatMin = 0;
double db=numeric_limits::min( );
to see which line is error.

i modified the code as below:
<br />
const double LogMath::FloatMin = 1.17549e-038;<br />
const double db = numeric_limits<float>::min( );<br />
const double LogMath::FloatMax = 3.40282e+038; <br />
const double dc = numeric_limits<float>::min( );<br />
but ended up with the same errors 
any other tips ?
Thanks for replyin

Hi,
I have created a new child window with the following method
AfxGetMainWnd()->SendMessage(WM_COMMAND, ID_FILE_NEW);
but when I display data on this window, the display starts on the left border of the window and then I need to give CRect.left +10 for the x-coordinate so that the data is properly displayed after the border line and
I can see the border line.
Can I avoid this +10 somehow so that I can directly use
GetClientRect(Rect) and print on Rect.left ?
Thanks

Take a look at SetWindowOrg() and SetViewportOrg().
Here[^] is an excellent article that you can use to alleviate any confusion you may have about those functions.
You may be right

This is all but completely meaningless without showing the code snippet that produced the error.

Does this[^] help at all?
(go to MSDN home page and enter DAO 3.6 MFC in the search box...)

Hey,
please help me. I've got a SDI-App with a non modal dialog. The dialogs only task is to choose parameter (e.g. in a listbox) for my application.
After selecting an item in the listbox (on dialog) the focus should move to my a control (choosen by listbox) in my cformview(e.g. CEdit - Control).
I handle the OnLvnItemChangedList message in my dialog. In this function I post a message (WM_SETFOCUS) to my (formview) window. But the focus returns immediately back to my dialog.
When I set the focus to my mainwnd (by mouseclick) the focus is in the right control. But how can I set the focus to my mainfrm automatically?
Thanx for your help

if u set focus to parent formview, the parent will set focus to its child which has focus before the parent gets focus automatically - so ur dialog gets focus back.
in ur function - OnLvnItemChangedList - u should tell formview where to send focus.
i.e. post a message to formview with wParam==control's ID, so in formview, u send focus to the control.

I tried your suggestion, but with partial success. When my dialog has the focus before I select an item on the listbox it works fine, but if the focus is on my formview or mainfrm and I select on item, the focus wents to my formview for a second and then switched back to my dialog...

I have an app that I need to shut down after a certain amount of time (eval version). I use a PostQuitMessage, which handles cleanup and works fine in most cases, but if I have a dialog opened through a DLL call (one of my own), it closes the DLL dialog, but not the main app.
What would be the proper (or clean) way to shutdown the DLL dialog(s), then the main app (dialog based)?
TIA

I have had this issue myself and would too like to know if there is some Zen approach that gives a warm fuzzy feeling.
Simply, the way I saw it was, that there is a higherachy of modal windows that have to be killed off in the right sequence.
It's interesting that the PostQuitMessage message you sent to the app seemed to be passed along to the right window rather than causing you trouble. It might just be best in that case to do the following:
while(::IsWindow(appWindow)) {
::PostQuitMessage(1);
}
If that doesn't work, do what I did, which was to start at the further most relevant child window and post to them each a WM_CLOSE message.
This may not be what you wanted to hear and I'll be watching this thread closely to see if anyone has any better ideas but in lieu of any other responses I thought you may at least like to know that there is commercial software out there that uses this technique

I tried doing this, which does seem to work...
I set a bool whenever I call my DLL.
<br />
if( m_bLibOpen )<br />
{<br />
PostQuitMessage(SC_CLOSE);<br />
}<br />
<br />
AfxGetMainWnd()->PostMessage(WM_CLOSE, 0, 0);<br />
This does seem to close multiple dialogs opened by my DLL, along with my main app, but somehow, it still doesn't seem "clean" to me.
I'm playing around with EnumChildWindows now...

It should work: I don't know Linux but this is standard C++.
If you explain what the problem is, maybe we can help.

As Cedric already noted, this should work.
What error do you get?
