I have a text file that looks like this:
9,1,3,Half,2.20
9,2,9,Half,2.20
9,2,7,Full,3.40
9,2,7,Return,4.20
9,5,2,Half,2.20
How I would sum the last column, all of the numbers in bold, of this text file and then make the result as the DataSource of a Textbox?
I'm trying to setup a form to search for data within an existing DataTable.
FilterColumnsComboBox.DataSource = WOTable.Columns?

Im trying to retrieve some rows from sql server having datetime column that matches the given value of the textbox in a form. The tables datetime column name is "DepDateDepositDate" and the textbox.text was formatted as longdate eg("Tuesday, April 06, 2010") I have this code below but it seems its not retrieving the data that i wanted.
Dim daBnkBok = New SqlDataAdapter("Select * From DepositRef Where Convert(varchar,DepDateDepositDate, 112) = '" & Convert.ToDateTime(clsGlobals.BankBook.bbDepDate.Text).Date & "' ", bbcons)
I have two text files, the first text file has two columns separated by a space (" ") and the second text file only has one column.
The column 1 in text file 1 and text file 2 match albeit in different order, what I'm trying to achieve is for every field in column 1 text file 2 I want to search for column 1 in text file 1 and display the matching column 2 field in column 2 text file 2.
Dim*OpenTextFile*As*String*= IO.Path.Combine("C:Test1.txt")
Dim*OpenTextFile2*As*String*= IO.Path.Combine("C:Test2.txt")
Dim*SaveTextFile*As*String*= IO.Path.Combine("C:Test2.txt")

View 1 RepliesI have a Data Table Column with multiple Rows of data. I need to search all lines of TextBox1.Text for any data that is identical to any row in the specified data column ("MCaddRG"). Also any identical findings need to be made into a new text file or a new form with a text box.[code]...

I'm working on VB .NET 2008.
Target: Bind dynamic datasource in a cell of a Windows.Forms.DataGridView depending on the selection in previous column. The grid must have 7 columns. If the selection on comboboxcolumn 2 or 4 is done, the datasource of comboboxcolumns 3 and 5 mus change using a query with previous selection as parameter.
In a first try to develop this functionality i've tried to use Telerik.WinControls.UI.RadGridView control. I've created a customized celltemplate with a combobox in order to have different datasource for each cell on the same column. All worked fine but seems to be some kind of bug in RadGridView, because when the combobox is presenting the list, after selection the list continued showing, doesn't dissapears as expected.
Ok, after several days of fight with RadGridView, I give up, and I tried to use same strategy but using Windows.Forms.DataGridView. I've created two classes one inherited from DataGridViewComboboxCell and other from ComboBoxColumn, in order to insert my own combbox or have the chance to have access directly to the combobox values. But the combobox showed is the default combobox not my own combobox.
how can I create a custom comboboxcell but using my own combo, and having access from outside to this combo?

View 9 RepliesLet's say that I have a DataGridView(myDGV) which I populate as follows:
'...
Dim strSQL as String = "SELECT col1,col2,col3 FROM myTable"

myda.Fill(myDtb)
myDGV.DataSource = myDtb.
'The above code fills the DGV with data from the underlying query
'of the DataTable.
'Supposing that I want to add an unbound Column to the end of the DGV which appears together with the data returned by the query, is it possibe?
I had a DataGridView that was bound to a Table in my typed DataSet. I recentyl added a new column to the table in the database and updated the table in the DataSet accordingly.Now, when I go to the DataGridView to update it, the new column does not appear under the "Databound column" list. I tried setting the data source to "None", then reselecting it. Still, it does not show the new column. I then deleted the DataGridView and re-added it to the form. Again, same result. However, when I select the data source, then click "Preview Data", it show the added column.

1. I have a multiline texbox and want to know if there is a way to search for a text in the textbox... The user should be able to input a search string and click a button to search all the entries of the string in it, just like ctrl+f
2. Is there anyway to make the textbox 'read only'? The textbox is populated by application itself, with some logs.. The only reason I chose textbox was because, I can't select an item and copy it from label..
Also, can a textbox include formatting, such as making some text bold, underlined etc?..
