Private Sub gridMed_Validating(ByVal sender As Object, ByVal e As System.ComponentModel.CancelEventArgs) Handles gridMed.Validating
Try
con.Close()
Dim r As Integer, row As DataGridViewRow

I have two list boxes and I need to compare them to check if they are the same. One will be populated with number I set and the other will be populated when the user clicks on certain buttons. But how would I go about comparing the numbers the user enters with the set numbers? For example if the first list was 3241 and the user enters 3241 how could I check that they were the same?

Interesting problem. I have a datagrid with several columns which are bound to an Access database. Here's the situation...I'm concerned with the 3rd column.This is what I'd like to happen... when the 3rd column(is a checkbox) is checked then column 4(TIME_USER) would be populated with the current time
Basically, this application is meant to keep track of tasks that the user has to do at a certain time of the day. When the user checks the checkbox it would record the time in the database for that task as to when they did it. I found some code from a forum that i changed to fit my needs, but it's not working.

Using VS2005. The code below saves a datagrid (datagridview1) to XML file and works well. But if newPat is true then I want to save the extra data in the XML file as well. But it doesn't work for some reason. When newPat is true it just saves the XML file as normal but without the extra row.
It seems this code is not working what so ever. I tried replacing
dr("patientName") = gridrow.Cells("patientName").Value
with
dr("patientName") = "test"
And it didn't work, it still saved the names that were in the grid.
newPat = true
For Each gridrow In DataGridView1.Rows
Dim dr As DataRow

I have one datagrid, as shown in the screenshot. However, I'd like to change the header to be more descriptive. The ones listed there are taken from the database column names, and so they're not good for eyes.

I need some suggestions on how to tackle this issue. I am fairly new to using ADO.NET and am running into difficulty populating a dataGrid.Basically here is what I want to accomplish:
a) on form open the dgvLOCATION populates with any records found in the database that match the customer ID that is displayed in a text box (the textbox will already have a value when the form opens)
b) when the value of the Customer ID textbox changes then the dgvLOCATION will change (I am already going to do this with a text changed event...I am just having problems with the query)
I am using VS Studio 2005 and connecting to an Oracle 10g database.I have also created a 'view' for the dataGrid since it will not any binding.Currently the dataGrid will populate will ALL database records on 'form open' if the field value of Customer ID is not null.
I am using the Query Builder wizard and when I enter the following I get an error.Select C_ID, ST_NUM, ST_NAME, CITY, RESIDENCE From CUSTOMER_LOCATION_VIEW Where C_ID = :TXTCID.TEXT
The error tells me that the query could not be parsed.

'this calls the connection sub
connection()
SQL = "SELECT * FROM Customers WHERE Surname Like '" & Textbox1.Text & "%'"
'this calls the DatagridFill sub
Datagridfill()
This is my current code, it searches for anything entered into the textbox against the row "surname", but I also have a first name row and a Order ID row. Instead of searching against one row, i want to to search all the rows, and fill the datagrid with anything it matches it with.

I am trying to load contents of an Excel file in a datagrid. The data in the Excel file is arranged in rows and columns. Every column has a column header. Now here is the anomaly. For some reason when I put a less than sign (<) before some of the values in the last column, the values become blank before they are loaded into the data grid. This behavior is not observed when the less than sign is put into the other columns. More strangely the values are retained in the datagrid even if the the < is put before the values of the first few rows of the last columns within the Excel file. I used the following code in loading data into the Excel file:
Dim con As OleDbConnection
Dim da As OleDbDataAdapter
Dim ds As New DataSet
