C# - Correcting Text In Database?
Mar 4, 2011
Question: In one of my database, there is a value in a varchar-field: Brokers México, Intermediario de Aseguro,S.A. Now I make a new column as nvarchar, and want to take over the old values, properly encoded. Now two questions:
A) In C#/VB.NET, how can I change México back to the proper value ("México"), before storing it in the unicode field (assuming I know the proper source-codepage)?
B) Is there a way to figure out the codepage, if I don't want to do it manually ? (well, asking is free, but I suppose there is none).

I have a dirty csv file that has 13 headers, but sometimes misses the last column value on some lines.
If the line has 12 columns, I would like to add ,0 as the 13th column.
Example:
2006/03/09,30403,7820,68,220,538,1956,14,3765,11384,26676,17932
2007/12/20,40796,13393,33,79,427,2604,11,4042,24974,44583,41561,7688
How can I read the file, and add ,0 to a line that only has 11 comma's and leave the lines alone when they have 12 comma's?

I am manipulating xml with lots of date of birth. XMLs are already loaded onto datatable. The format we need is "dd/MM/yyyy" The dates are messy such as "dd-MM-yyyy" or "dd.MM.yyyy" so I am thinking to write a function that will auto correct on a set of predefined separators to a correct format. so I am thinking to do something like this but of course, this won't just work.i cannot use replace to replace an array. If i can just do that, everything would be fine. Hope someone can point out a way around. [code]

Ive figured out how to open a file to read and then display it, and i can probably work out how to write a string to a file. The part i am stumped by is this. Say i open a text file with the following text I has a badger i then want to correct this to I have a badger.
Its just an example and not for a grammar corection program. What i want to do is detect what was said and alter it acordingly. I presume this would come under string manipulation but i cant find any details on this.

I have a form that I am loading text (strings) from a database into a label.text (so the text from the database shows up into the label) I have done this code in a class that keeps all my database stuff seperate.
Public Function getQuestions() As List(Of String)
Dim question As New List(Of String)
objConnection.Open()
objReader = objcommand.ExecuteReader
[CODE]...
Within the form that the label is in I have done this code
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Label1.Text(db.getQuestions().ToArray)
End Sub
I am basically making a quiz, so that when the form loads, question 1 is on there is 4 possible answers. You then press next button and it goes to the next question.

I'm trying to make a small database out of text boxes and text files, something where sql would be overkill, not to mention beyond my experience. I want to be able to write the contents of the text boxes to a file.txt (the easy part) then being able to retrieve them back out into individual text boxes. How would I pull this one off?

BirthDate Data Column
DataType System.DateTime
DefaultValue <DBNull>
NullValue (Throw exception)
The above properties are from a database field. All other options for "NullValue" are rejected.
A text box is bound to the field.My question is: what (empty, nothing or null) value can I put in the text box that the database will accept.

I built a game that has three forms (the game, player info, and scoreboard). When you die the Player form shows and has a text box for the user to into their name and then they click submit. After they click submit the Scoreboard form shows and their name and score is showed in disabled text boxes. Also in the Scoreboard form are two List boxes (one for their name, and one for their score). The list boxes are connected to the database through a databinding by dragging them over from DataSources into the form.
I would like for the information in the Name text box and Score text box to automatically be inserted into the database when the Scoreboard form is loaded.How do you insert text from a textbox into a database?the Name is the first column in the database and the Score is the second column in the database.

I have the setup project built, but I can't figure out how to publish it so I can put it onto a CD. I am working in Visual Studio 2005.

I using MS Access 2003 Database with VB.NET.
I have wrote a SQL statement to insert the RichTextBox(RTB)'s text into the Access DB but got error saying syntac error. I cannot figure out what went wrong.
When inserting data for RichTextBox, i use the TEXT property- rtb.Text . usign rtb.RTF also got error. The data type in Access is :Memo ( to store larger size text ).
INSERT INTO company (compName, compDesc ) VALUES ('" TxtName.Text "' ,'" rtb1.Text "' )
Is anything wrong with this SQL for RichTextBox?
When i remove the rtb1.TExt and just insert data for the 'compName', no error found on syntax.
