This type of parsing is better handled by lexer/parsers. Antlr[^] is a nice parser generator, which has a C# parser[^] to get you started.
You can probably do the same thing with a regular expression, but it's going to be very complex.
Take care,
Tom

Tom, absolutely this type of parsing is better handled by lexer/parsers. But for my purpose it will be much easier to construct rather long and complex regular expression than bring into play Antlr.
So far with my regular expression I can split only at unary operators-punctuators (like +,-,:,=,{,},[,] etc). Can somebody help me with binary as well (like ==, ++, --, != etc)?
So I coud have both just in one expression.
Or even simplier, how to have in one regular expression '=' and '==', '+' and '++', '-' and '--' respectively?

First of all, I would like to apologize if this question has already been asked and answered, but after a brisk look through the forum, I did not see a thread.
I would like to create an application that stores data inputted by the user, but am somewhat new at database deployment. I am used to using an SQL Server environment. What would be the best database to use between MS Access and SQL Server Express, and what would need to be added to the deployment package to use either of these. Example, if the user does not have MS Office installed, and I use MS Access as the database, what would I need to include in the deployment package to allow the application to use the database? If I use SQL Server Express, what needs to be installed on the client's computer to be able to use it?
Sorry for the newbie questions, but as stated earlier, I am not experienced in individual database applications.
Thank you for any help you can offer.

This depends on the way that you want the database to be used. If you want to have a single application using the database at a time i suggest, MS Access. When there are several users that have to use the same database...use Sql Server.
The Prodigy wrote: if the user does not have MS Office installed, and I use MS Access as the database, what would I need to include in the deployment package to allow the application to use the database
If you connect to the MS Access database using OLE DB (which comes along with Windows) the user doesn't need to have Ms Access installed for the application to run, only if he wants to modify or view the data within the database.

When you use SQL Server database a good practice is to install SQL Server on a server machine and configure all applications to use the database from the server.
There are 10 kinds of people: those who understand binary and those who don't

Hi....
The code will look like
Range usedRng1 = (Range)_ExcByAppWorkSheet.get_Range("A1", Type.Missing).Select();<br />
usedRng1.EntireColumn.Hidden = true;
Regards,

I want to put a date into a field of a GridView bound Access table. Really I can't get any type of data to work, the field is a VarChar. I tried the following with the UpdateCommand...
[Lastupd] = @DateLabel,
<UpdateParameters>
<asp:ControlParameter ControlID="DateLabel" Name="DateLabel" PropertyName="Text" />
</UpdateParameters>
Nothing even displays in the GridView with this Update Parameter
I also tried this in the GridView1_RowCommand method...
GridView1.Rows[index].Cells[17].Text = "1";
and this gives me a "Data type mismatch in criteria expression" Only the .Text property is exposed and not .Value in any of the public methods of the DataView control.

This is a trivial homework assignment. Have you looked through the methods on the string class and considered which ones would help you to achieve this ?

What if you could replace all double dots with single dots?

You haven't specified if you want the result as characters or strings. You can use the Chars collection to access individual characters in the string, and you can use the Substring method to get a part of the string.

A regex should be the easiest way to do this:
((\d+)[^\d]+)+

Or even more simple:
string[] numbers = Regex.Split(mystring, "[^\d]+");

Is there ant where in CodeProject any samples for that?
Thanks.

If you can pay(or not) you can use Infragistics...

I recently was watching a video about C# and came across a great shortcut. Inside a class if you type "prop" and then press [TAB][TAB] a property generator is created right in the code for you. I find this very cool and time saving when creating a lot of properties for a class. I was wondering if there are any cool little short cuts out there???

They are called "snippets" and intellisence will show you those that are available. You can also create your own.

Have a look at the following MS VS2005 Code Snippets[^] You will pretty much find a snippet in this collection for all your needs.

Hey guys and girls, I have a question that might sound stupid, but
I cant find a solution to it, so I am asking you.
I want to name my variables on the fly, meaning, I only know in the middle of the run, how
many variables to create and therefor I want to run inside a loop and create in each iteration,
a new variable with a different name.
example:
foreach (long EUI in EUIarray)
{
List<Object> EUI = new List<Object>();
}
Imagen that I want to create in each iteration EUI_1, EUI_2 etc.
thanks for your help

I'm pretty sure you can't, but why would you need to do that? Whats wrong with just using an array?
