I have read this statement in a book.
"The results of expressions which use same variables with increment operators more than once are unpredicatble in C Language"
int i=0;
i=i++ + ++i; //3 not 2
-----------------
int i=0,j=0;
j=i++ + ++i; //2 as esxpected
You can try with lot of examples...

It would indeed seem that way. If I do the following in c++ I do get the expected result
int a;
int b;
a = 5;
b = ++a;
b += ++a;
|
|
|
|
|
Try to use the variable 'a' more than once(with increment/decrement operator) in a single expression and assign the result to 'a' itself.
You will get unexpected results.

However. It's strange, C++ gives 14 at the same time C# gives 13.
The different interpretation of statements?
A

|
|
|

In C++ this expression results in undefined behavior. Look
here[^] for details.

Hi,
try the article search for "sms", there are lots of articles on cp about this topic.

Hi,
You need to use a Mobile Phone manufacrture's library. Using that you can send sms to from your application. These libraries have very simple interface.
There are two way to send the sms using these libraries.
1) Using a mobile handset
2) Using a getway.
One such library I do remeber is from Nokia.

Hi,
Can anyone have idea about how can i get a sub(small) dataTable from a huge dataTable?
datatable.select() returns only datarows that is time consuming in case of huge database. I want a fast method.......
Thanks ![Rose | [Rose]](https://codeproject.freetls.fastly.net/script/Forums/Images/rose.gif)

I don't know if this is the best way but I usually go back to the database to return any 'sub' data. For me this has always been the fastest method and would do this unless I need to limit network traffic for some reason.

Query in 30,000 for 10 times in 1 min is simply killing the aplication....
I want any System mechanism to solve my problem.

Hi,
maybe the FileSystemWatcher element from the Toolbox can help you to solve your problem.
|
|
|
|
|
Thanx a lot for the feedback. i will look into it
|
|
|
|
|
I might be missing something here but i did something along these lines with the FileSystemWatcher class in the System.IO namespace. I made it watch the C:\ drive and then I just hooked up it's events so that is would write out the name(path) of the file in question and the event that was taking place along with the time to a text file. However this was on XP and i'm not sure what the difference is with VISTA.
enjoy

Oh, it's you, David! Almost didn't spot you under 4 million members... 
Anyway, there are several articles here presenting Undo/Redo frameworks, for example this here[^].
If you still have problems with applying the undo pattern on the objects the drawing tools program uses you could ask your questions in the article's discussion - the original author will be notified that there's a new question regarding his article.

Please don't change your question completely while someone is answering it - now the answer doesn't match the question anymore 
Again, the article's discussion is the appropriate place to ask this question, too.
