Parsing Error On Adding A Csv Text Value Into A DataTable In .net
Apr 19, 2011
I'm trying to add records from a CSV file into a dataTable in vb.net, as follows:
dim myObjAdapter as new myDataSourceAdapters.myTableAdapter
dim myObjTable as new myDataSource.myTable
myObjTable = myObjAdapter.Getdata
[Code]....
PS: in CSV file, the decimal digit is "." and if I add directly a record into table, using "." as decimal separators, the numbers get right format.
There is a kind of settings to change, or option to enable/disable on adding this records to do the right adding?

I have a session which contains a datatable and also have a function which returns a datatable. I need to add these two. How can I do this? The below code is to be replaced with correct code.
Session("Table")=Session("Table")+obj.GetCustomer() where obj is an object of the business layer.
The '+' sign cannot be used to add these two, so how can I do this?

The Form Designer in the IDE is no longer working properly. When I create a new project, the Form Designer will work, but after I save it and close the IDE and reopen the next day the Form Designer no longer shows the form and instead says "To prevent possible data loss before loading the designer, the following errors must be resolved: An Error occurred while parsing EntityName.Line 2, position 62" If I click ignore and continue, then it just displays a blank form with no controls. The problem appears to have started after I unistalled and reinstalled VB2008 Express.

I am using NiceEdit to format text in text areas, it displays a toolbar over the specified text area, I created a test page, its working, I Response.Write the content of the text area after being formatted, and its okay, I created a break point to see whats being read, it was all fine.Now I moved to the real page where I should implement this text formatting, it simply did not do anything, the toolbar is shown and its working, but when I submit, nothing is being stored, i created a break point and the content of that text area was nothing, empty "".I went further and put Response.Write(textArea.text) then Response.End() and I got the error:XML Parsing Error: no element foundJust in case, the script I am using for the formatting NiceEdit toolbar, and this is the same script i used in my test page and worked just fine, the script is:
<script src="../nicEdit/nicEdit.js" type="text/javascript"></script>

i have a problem when add data into dataTable. The problem is that after populating the dataTable with the 1st, and when adding a 2nd column, the row that contain the data is not at 1st row of 2nd column. It is directly under 1st column row. For example, column 1 has 10 rows of data. After adding the 2nd column, the data is at row 11 instead on the 1st row. Can someone tell me how to add the data for 2nd column so that it will be in the 1st row. Code for adding the data
Dim col1 As DataColumn
Dim row1 As DataRow
col1 = New DataColumn("Column 2", System.Type.GetType(" System.String"))
dTable.Columns.Add(col1)

How do I go about adding a ButtonColumn to a DataTable.
I am basically using a DataTable as the DataSource of a DataGrid and need to add a ButtonColumn to the DataTable so that when I DataBind it to the DataGrid it all works.
Although when I try
dt.Columns.Add(buttonColumn)
This is not allowed. It has to be a basic DataColumn.

See the code below which is triggered on a datagridview row validation event where the datagridview datasource is a datatable.
The messagebox shows that it loops around as expected populating the datarow with the expected values (NOTE: There are no primary keys as this is a college assignment with specific requirement and all fields can be nullable).
I had to use ImportRows as AddRows would always error due to "This row belongs to another table" the odd thing was the values were different and again the table contains no primary keys.
The code below runs but never adds a datarow to the dataset datatable "Bookings", does anyone know what the problem might be?

I am trying to add a datatable to a database. Here's what I've been trying:
Dim newDataTable As DataTable = New DataTable("Example")
VocabularyDataSet.Tables.Add(newDataTable)
SqlDataAdapter1.Fill(VocabularyDataSet.Tables("Example"))
I've tried various incarnations of Fill and Update. But the tables will not save on the database!

in vb, you can use text which is in textbox instead of numerical expressions. I mean, if I write 50 in textbox1 and also I can write like that code:
Dim result As Double = TextBox1.Text + 0.4
as you see, I didnt convert any type but it works in vb.net
But I want to learn what are disadvantages of this using?
(I am just talking about arithmetic operations)

I am attempting to parse multiple lines of text from a text file using regexpressions. I am using vb.net with visual studio 2008. At the moment I am filling my datatable with the text file information and am able to return each line of text and parse the first set of numbers that I am attempting to break up. I have multiple string with varying lengths of character lengths and numeric lengths however the delimiters are sometimes different. Sometimes will be whitespace and sometimes will be whitespace and chars. But is always 2 spaces. Here is my code:

I have a rich text box full of encrypted data split by ";" and I have
Dim Pass, Data, Game1, Game2, Key1, Key2 As String
Dim PassEnd, Game1End, Game2End, Key1End, Key2End As Integer
Data = showencrypt.Text
PassEnd = InStr(showencrypt.Text, ";")
[code]....
Pass gets decrypted ok, and Game1 gets decrypted ok. Key1,Game2,Key2 are all the same as Game1 though. Is there something I am missing? Why is it setting all of them the same? I've tried settings the Start of the InStr's at the previous End but it doesn't work.

I'm toying with an idea that would require me to parse a text file that contains a SQL statement. (i.e. Select * From Customers) I would like to be able to programmatically via Visual Basic identify key words, table names, comment lines, etc.So, how do compilers handle such a task? How does a SQL database handle such a task? All of the parsing tools are for CSV files with some sort of consistent delimiter. I'm wondering if I need to read the file one character at a time and then do some sort of comparison.
