Now, I want to place the rows from foundrows into an empty data table.I did what I thought was the obvious but that only returns a bunch of rows with no data

Which is fine, if I want to use mysql update all I have to do is call something like: sqlUpdate("test", "test", 0, "test", test) I was wondering if I could do the same with the SELECT statement and make a function. I cant think of a way to do it though...
sqlConnect() Dim cmd As New MySqlCommand With cmd .CommandText = "SELECT * FROM users WHERE username=""" & lblAccountName.Text & """"
[CODE]...
The data I would want to extract would be different every time.
IT STILL GIVES A MSGBOX IF I SELECT THE CHECKBOX BOX OR NOT ....My code below will redirect to Google in both conditions: If the user selects the checkbox, then it will redirect to www.google.com, but if a user forgets to check the checkbox then it shows the msg box with an ok button. When I click on ok it should redirect to www.google.com
I want When a user forgets to check any of the checkboxes to show a msgbox with an ok button and stay on the same page. Otherwise if user selects any of the checkboxes then redirect to google
I am attempting to have my program select a file, create DataTables and then perform some other functions. I want to be able to open another file and re-do the same steps.The problem I am having is that I add columns to my Datatables and when I try and to open another file while one is already open I get a message that a column of xyz is already added how do I properly "clear my datatable" or perhaps that isnt even the correct approach? Here is the code I have that Opens a File

I have a datatable and I would like to get the MAX number from this table where Term Number (first Column) is a certain value. If my datatable is declared as dtMyTable, I'm assuming I need to use dtMyTable.Select(), but I'm not sure if this is the best way.
I'm trying to get value from Datatable after Select Method.Select Method should return only one record.
Dim y As DataTable = CType(HttpContext.Current.Session("tb"), DataTable) Dim products = y.[Select]("StnID" = "'" + stnID + "'") Dim size = DirectCast(Products(0)("Shape"), String)
if I replace products with y--(DirectCast(y.Rows(0)("Shape"), String), it works.(which is before Select method, so it's useless) products is datarow object and I can't seem to get the value same way as datatable.How do I get value from datarows?
I have pulled information from a database into a datatable (dtCustomerInfo) then I expanded on the columns by processing the data and I can display this in a datagridview without any problem. However, the data is in detail and I want to ultimately summarize by customer name.The code below has a commented sql statement that is the statement I ultimately want but it is not working. However, the idea is that I want to Select from one datatable into another but run aggregate sum on several columns so that I will get one record per customer showing totals for each column.So I broke it down to just pull all data possible into the second table.[code]I do know the grouping in the current select * statement does nothing but my issue is more that the columns do not show up.
I need filter for multiple values on one column using the DataTable.Select method.
Dim totalFatal As Integer = m_DataSet.Tables("tblAccidentNonMotorist").Select(String.Format("[AccidentNumber] = '{0}' AND CONTAINS([InjuryClass], '"01" OR "02" OR "03"'", accidentNumber)).Length

I am working on a vb.net app for a handheld using Windows CE and I have a few columns of data loaded in a datatable from a text data file. Some of the records can have duplicate Account IDs so I cannot use a primary key. What I want to do is take an Account ID entered and filter on just those records. I need to loop through all records with this Account ID, make updates to any of them and then clear the filter.
how to set a filter on a column based on a given string such as an account number? And loop through these records? Can I modify the records at that time?
I want to filter a virtual table (DataTable) and return only matching items into another datatable which eventualy is the datasource of a datagrid. The datagrid displays the result. The purpose is to reduce the network traffic while still providing the function. So as type on the textbox provided, the virtual table which was earlier populated by a disconnected Ado ADO connection, is re-queried and filtered into the new datatable.
how to go about this. It is a windows application and i am using dot net 3.5, VB 2008.
Here is my code:
Dim filtDT If MYQDT.Rows.Count <= 0 Then MsgBox("The data is been cleared")
I am trying to use the Select on a datatable and am having some trouble. I got it to find a match on rows in a datatable I fill with data in multiple columns. But I cannot seem to loop through the results to do something with it. Here is my code below. The table is already filled with data.
I have a dataset, which have a column create_date which have value(5/12/2011 12.54.00) , but i want to select the value from dataset with date only not by time (i.e. 5/12/2011),[code]
I have the following code that loads an XML file into a datatable (I went this route because I do not know how to query XML directly). I want to use the Select method to return a row where "age = 72". However, I can't seem to get this to work. Also, if there is a better way to search through a datatable for specifc values that would not require iterating through the whole table to get the results
i have a datatable that contains numerous postcodes in the following format[code].....
there is always a space before the last 3 characters now i need to filter the datatable against a list of excluded postcode areas..these are the following format:-
BT1 BT2 BT4 BT40
so its either 2 letters & 1 number or 2 letters & 2 numbers, no 2nd part to the post code..i have a little function which builds the string, and then removes the rows from the dataset like so (ive pasted in an example postcode string)....[code]....
which obviously brings out no records as they all have full postcodes the issue is, i need to be comparing only the first half of postcode BTxx bit but cannot use a % wildcard, as this then would bring out BT40's when i only want, in this example, BT2 & BT4's..so is there a way to make it compare against the first half of the postcode?
