An external variable must be defined, exactly once, outside of any function; this sets aside storage for it. The variable must also be declared in each function that wants to access it; this states the type of the variable.
The basic rule is ``define once; declare many times.''

Sorry. I did it by mistake. I'll explain the problem for which I want the solution. I want to control the speed of the animation. I did this with the variable called "speedcntr"(extern defined in main.cpp). I use this variable to change the speed between way points. For this I call a function called "SetSpeed" which is defined in a file called Character.cpp from a file called "AI.cpp". It's working fine. In addition When the Charcters load initially they should be playing with a specific animation speed(Different for each Character). For this I've to change the value of this speedcntr variable before each character's load(with in the same scope). Is it possible or any other solution to my problem?

Hi,
It seems you want to store multiple values. Dont you think you can use arrays or some other data structure for this purpose.

Why are you reposting when you got replies to your first post.

What the hell ?
Instead of voting me down, you could have looked at the link I gave you. This was an article about an analog clock control. But maybe you are too lazy to read it ? Maybe you want that people do the job for you ?
Stop spamming the forums, you already got helpfull answers. If you can't manage to read or search an article, then go to rentatcoder.com and hire somebody to do the job for you.

Just a guess, but is "running" timedate.cpl an option?

Hi all,
I have a list control and a tree control together in a sdi application which is divided using splitter and both the controls are displayed in different views. When i click on parent in tree all its child are displayed in list control. Now, my problem is if i want to delete presently selected item how can i do it?? that is if selection is shown on tree then that item should be deleted and if selection is shown on list control then it should delete that item?
thanks in advance

You would need to get the selected item first, it could either be on the tree or in the list.
If it's in the tree use CTreeCtrl::GetSelectedItem. If this function returns null it means nothing was selected in the tree. on the other hand if CListCtrl::GetFirstSelectedItemPosition returns NULL it also means that nothing was selected in the list control. Since you now know that the item is selected in the tree/list you can delete that item.
Hope that deletion won't be a problem for you. It would only be of how to get the selected item from the list or the tree

No actually the problem is when i click on parent item it get selected and then i go and select list control item and then press delete....
now what happens is as i check that is any item is selected from tree control it returns that parent item now how can i do it?/

|

ok. in that case you can keep the index of clicked item stored in some member variable and use it while deleting

 I think u can try with this :-
try using GetCurSel() function.
use the Dlgitem's object & GetCurSel() to select the Currently selected one then delete it !!

Did you know that you can search on articles on CP ? This[^] is the first result to a search for 'Analog clock'.
|
|
|
|
|
you would need to create your own clock or need some third party control. See here[^] and here[^] for examples

Hi All
i want to make a backup file which is like this [code]Copy From System to USB or USB to Sustem[/code]. I am able to monitor a usb device. So plz help me

you can use file copying.
Here you can copy all files of USB to System and vice-versa.
so take a look for file copying.

Hi, I'm trying to get into C++ and I was wondering about the class and method names.
I'm hailing from C#, where everything is written fully and all names are immediately comprehensible.
However, it seems in C++ mostly abbreviations are being used. Is there any good reason for this or is that just because C++ has been around since long before Intellisense, so it's just a matter of convenience?
Thanks.

ya! it's only a matter of convenience to avoid long variable names and distinguishing them from being local or member variables. for example there is oneHungarian Notation[^] that can be followed. If you feel that the people who follow you, should understand the code by just having a glimpse at it, it would be better to use a notation. on an ending note - > If you use your own:DOCUMENT IT VERY CAREFULLY.
