I wrote a class for expressly that purpose.

You've not given enough information about the format of your string, so this regex will match the given string, but might not work on other strings:

(\d+),(\d+/\d+/\d+),(.+)

I wrote a class that supports quoted strings.

It should do exactly what you want. To see it work, run the demo app.

I didn't read it closely; does it support escaped quotes within quoted strings?

No, but you could always extract the quoted string as a field, and then create another parser instance and let fly.

string data = "my mother,the car,"other stuff,'my,other,stuff'",lastfield;
StringParser parser = new StringParser(data, ",", "\"");
string quotedField = parser.GetField(2);
StringParser parser2 = new StringParser(quotedField, ",", "\'");

This should match a CSV line with one or more values, inluding quoted values containing commas and encoded quotes:

("(?:[^"]|"")*"|[^,\r\n])(?:,("(?:[^"]|"")*"|[^,\r\n]))*

(No guarantees, not tested.)

That should be handled. [^"] matches any character except a quotation mark, so that includes newline characters aslo.

Use Split if you need to get all the words in an array. If it is some specific word or phrase, use Regex as replied earlier.

C isn't that hard: void (*(*f[])())() defines f as an array of unspecified size, of pointers to functions that return pointers to functions that return void

Applying color to the string while writing in a word document

Hi all,

I m trying to read the contents from one word document and writing in a newly created word document. I wish to apply a color to the string while writing. I tried the html tags as follows

swFile.WriteLine("<body><Font color=#FF0000 Face=courier new>" + s + "</font><br>");

the above code is working, but the original alignments(i.e tab spacing and other allignments) is changed for every line.

for eg, original: ashok ashok ashok ashok age 22
output:ashok ashok ashok ashok age 22 (color:red)

when writing normally all the indendations are coming properly as of in the original document.

kindly help me out.

You can create a Range object and use its Font.Color (not sure if it is color of forecolor).

MySQL connection problem with net 3.5

shaf21130-Dec-08 23:08

Hi, I'm using Windows XP Pro and VS 2008 Team Edition. The project I am working on is targeting .NET 3.5. I downloaded the MySQL .NET connector 5.2.5 and installed it. Installation was successful. I could even find the updated machine.config file. But whenever I try to reference any of the classes (ex: MySql.Data.MySqlClient ) I get this error:

"The type or namespace name 'MySql' could not be found (are you missing a using directive or an assembly reference?)"

Now I have tried everything I could. Copied the MySql.Data.dll to .NET installation locations for both 3.5 and 2.0. Installed the dll in the global assembly cache using gacutil, copied the dll in my project's folder, in short anything and everything that I found I could do using web search and as such, although I was not supposed to do anything, the installer downloaded from MySQL website should have done everything. But the problem remains.

Can anyone here please provide any solution? Thanks in advance.

String Concatenation

What is the best way to contact three strings.

Method1
string key = "test" +"::"+ "test";

Method2
sting key = String.Format("{0}::{1}","test","test");

Is there any memory enhancement in using the second method?

Thanks!
