I need to be able to write some data sepererated by commas (3 Datas) then go to next line. I am using the following code:
CODE:
Dim textfile As String = "C:Documents and SettingsAll UsersDocumentsDesktop CalendarSaved SchedulesSchedules.txt" My.Computer.FileSystem.WriteAllText(textfile, Me.ComboBoxMonth.Text, False & Conrolchars.Newline)
I worked around to modifying regular expression below but i could't get what I need. I google it, many things found but not for what i want. Dim valid AS Boolean = Regex.IsMatch(TextBox1.Text, "^(,?d+){0,20}$")Allow numbers exactly like 32,1,6,32,12,21,21,54,675,8,4,3,2,9,0,21,21,21,43,744 in TextBox1. Perfect.
View 4 RepliesI want to create a string of values separated by commas from a MatchCollection. So far the only way I have been able to make it work is by using a �For To� loop to load an string array one at a time then joining the array. IE is there any way to join the value properties of each match object?
View 6 RepliesI'm new to Comma Delimited values. What I'm trying to do is load up a text file which has employee info separated with commas
like 1/1/09, John Smith, (555) 555-5555, 101 S 1st Street and has numerous rows of info like this
so what I want it to do is just write this info to 4 different textboxes
like txtdate would just have all the dates of employees listed in rows or multilines
then another text box for names and so on.. Right now I just have it all being written to one text box.
I'm not sure how to separate all the information accordingly.

I have a comma separated file that has commas in the data, so using Split() doesn't work. I tried to use Jet 4.0, but a column has text and numeric data in it, so half of the values return null. After researching for hours and getting nowhere I attempted to write my own split function that checks for quotes so it can skip past the extra commas in the line. I fiddled with it for a few hours and got it almost running. [Code]
View 7 RepliesI'm sure this is a common problem but I have been unable to find a good solution anywhere.I am using line.Split to read a CSV file.Unfortunately the data contains strings that have comma's in them like so:
"Singer","Hasselhoff, David",21,15
This results in 5 strings:
Singer

I have a string like
human, roti, makan, ghar, house, language, english, india, US, master, teacher, html, code, asp, jsp
i need code for find the input string.
I decided on a comma separated data file, saved as a text file. This is for data that will not change. After loading the data from the text file; then throughout the lifetime of the program the data can change. The data can then be saved back to a different binary file. The idea is to have a save state system going.Does anyone have a suggestion or is opposed to the idea. Is there a simpler way to organize something like this?

View 1 RepliesI am reading datas from MSWord Document. I know how to read the file. the sample text in my MSword. C# code review checklist. My current client uses PSP extensively, so I've been putting together a checklist for reviewing C# code for use on our new project.
1.Are exceptions used to indicate error rather than returning status or error codes?
2.Are all classes and public methods commented with .NET style comments? Note that <summary> comments should discuss the "what" of public methods. Discussion of "how" should be in <remarks> blocks or in-line with the code in question?
3.Are method arguments validated and rejected with an exception if they are invalid?
4.Are Debug.Asserts used to verify assumptions about the functioning of the code? Comments like, "j will be positive" should be rewritten as Asserts.
5.Do classes that should not be instantiated have a private constructor?
6.Are classes declared as value types only infrequently used as method parameters, returned from methods or stored in Collections?
7.Are classes, methods and events that are specific to an assembly marked as internal?
8.Are singletons that may be accessed by multiple threads instantiated correctly?
9.Are methods that must be overriden by derived classes marked as abstract?
10.Are classes that should not be overriden marked as sealed?
11.Is "as" used for possibly incorrect downcasts?
12.Do classes override ToString instead of defining a Dump method for outputting the object's state?
