Actually, I was not aware of this. Smile | :)

If you see implementation of atol(called thorugh _wtoi),
it extract number using this loop

char* nptr="0155";
 int total=0
int c=(int)(unsigned char)*nptr++;//c is 48 here
while (isdigit(c)) {//0,1,5,5 will return true here.
    total = 10 * total + (c - '0');
    c = (int)(unsigned char)*nptr++;
}
return total;

using _wtoi, don't think it's possible.

How is it that you are using CButton but not using MFC?

What did not work? checkState should have been BST_CHECKED, BST_UNCHECKED, or possibly BST_INDETERMINATE if using a 3-state button.

Finding deleted virtual keywords

Hi All

I'm facing the following strange thing on my code!
I discovered that in my derived classes the keyword virtual has been deleted when the base class got it.
It's incredible because I have tons of code where this occurrs!!

Do you know a way to trap this in my source code?
Does exist some tool or trick or compiler option maybe?

Thanks to all
Manu

What do you mean by "has been deleted" - did the editor delete it or what?

Anyway, it really doesn't matter. If a method is declared virtual in a base class it is implicitly virtual in a derived class even if it is not declared as such in the derived class. This makes sense as the entry in the vtable is already there (from the base class declaration), no need to declare it again.

But I still don't understand how it got deleted...

Cheers
Steen.

Hi to you all,

I have a program that uses both microsoft word and outlook. I use them through automation, so I include both msword9.h and msoutl9.h. It turns out that both libraries define _Application, Panes, Selection and ApplicationEvents (and they do not seem to be identical either). I have now taken the easy route by renaming those 4 classes (to stuff like _Opplication, OSelection, etc). This does the trick, but it does not leave me with a good feeling.
Anyone have any better ideas?

Thanks in advance.
William

Did you use ATL via #import? You can control namespaces if you do that.

if you ::ShellExecute(null, "open", "myFile.ext", null, null, SW_SHOW);, then, ,the system opens automatically the program associated to the extension.

In the example above, it did know.... It was ..."file.ext"...

If you are talking about files loading in your software, and you are using MFC, then CDocTemplate has a member function MatchDocType you may want to look at.

If you cannot tell the type by looking at the extension, or by looking inside the file, simply accept your PC does not have psychic powers.

If you are adding file names to the control, how could you not know it's extension?

how to find hidden windows restricted due to mandatory profile

Hi,

I have administrative access on the domain but mandatory profile on my login user is causing me not to see the display settings. When I right click in black area of the desktop to bring display properties windows, I can see just effects tab, all other tabs (for screensaver, coler scheme) are not seen. So I wanted to bring these windows by some other way and want to change the color scheme and save it. How may I do it programatically? My operating system is windows 2000.

thanks

Hi all,

I want to write an app which should install SNMP services in the target system. Sysocmgr.exe can do this but I need the required redistributables. Can you plz tell whether SNMP services redistributables are available or not? Is there any other option by which I can install SNMP services in the target machine through MFC?

Thanks in advance.
