Specific Columns To Show Up In DataGridView?
Oct 6, 2009
I only want specific columns to show up in my DataGridView, so I run a dynamic sql query to select specific columns from a table on a sql server(I know its slow, but its only used once a day). However, every column from the table shows up in the datagrid, and I can't figure out what i'm doing wrong.
Public Class Assign_Priorities
Dim connect As New SqlConnection("Data Source=IRNTS4SQL;Initial Catalog=Materials;Integrated Security=True")
Dim ds As New DataSet
Dim da As New SqlDataAdapter("SELECT [Priority], [Tool Type], [Lot Number], [Process], [Priority Notes], [Quantity], [Time Job Entry] from [FPAD Process Log]", connect)
[Code]...

I need to get a table on my Form that has different columns from differen tables.As I call many tables by their Identity ID, I also need a way to show the information from that table.I created a query in my TableAdapter which selects information from 2 different tables. Tested it in the query builder and all was OK.I tried to put an empty DataGridView onto my Form and inserted the correct BindingSource for my Data Source.I then added a query and selected the query I created in my TableAdapter.

I wonder if it is possible to find a specific row and specific columns in data base file (Access) . You see , I am using a DataGridView control to show only SOME of the columns (fields) of a table from an Access file . For example , lets say that in the DataGridView control I only show the following fields :Field1 , Field2 and Field3 .Now , when the user selects an entry in the DataGridView control , I want to insert the text from Field4 into a text box on the form .
The problem , however , is that I don't know how to get the specific row in the data base file and also I don't know how to get the text in column (field) Field4 of that row .One thing that might be important is that the index of the row in the data base file is not necessarily the same with the index of the current row in the DataGridView control . This is because in the DataGridView control the rows are order by the contents in the ID Field .ol .

The below picture is generated by the following code:
Public Class Form1
Private Sub Form1_Paint(ByVal sender As Object , ByVal e As System.Windows.Forms.PaintEventArgs) Handles Me .Paint
[Code]....
What I want to do is when I click on each grid on the form (Touch Screen), a tooltip of some stored information about the grid appears on screen. For example, if I click my mouse on square 6,8 then some stored information such as grid number, grid name, level...etc appears on the tooltip on the screen.

Basically I can get all the data within the grid present in the "print preview" however they are not within the right columns , and all the data overlaps , making the printout look very messy !
I need to be able to get all the data into their specific columns , e.g all the names under the name column .
This is my code so dar =]
PrintDocument1.DefaultPageSettings.Landscape = True
Dim Myfont As New Font("Courier New", 10, FontStyle.Regular)
Dim MyFontSmall As New Font("Courier New", 8, FontStyle.Regular)

This doesn't seem like something that should be confusing or difficult, but I'm having a hard time finding the answer to this problem. I want to copy columns with their data, not rows, from one large DataTable to a smaller one.I have a DataTable with many columns of data (around 20), and a string array of the columns (4 ) that I want in the copied DataTable. Is there a reasonable way to accomplish this task?

SQL statements:
SQL = "SHOW TABLES;"
Try
conn.Open()
The remarked area works fine when I'm accessing a specific table. I've successfully inserted the products_model field into the combobox too. The datagridview does show the table names in the db using the SHOW TABLES sql statment, but I'm not understanding how to get this info into the combobox instead.

Situation Overview I'm using Ext.NET GridPanel to display a list of projects which has tasks (i call it Sprints) inside it assigned to some user and a status. So I get this kind of relation:
SprintOwner -> UserID
SprintStatus -> SprintStatusID
In my GridPanel I display my sprints grouped by projects and I use the relationships to show their names instead of their IDs (SprintStatusName and UserName). It's in portuguese but I find it useful to show:

I am trying to program a noise reduction algorithm that works with a set of datapoints in a VB.NET DataTable after being helped with my other question. Basically, I want to take two integers, a coordinate value (yCoord for example) and a threshold smoothing value (NoiseThresh), and take the average of the values in the range of (yCoord - NoiseThresh, yCoord + NoiseThresh) and store that number into an array. I'd repeat that process for each column (in this example) and end up with a one-dimensional array of average values. My questions are:
1) Did anything I just say make any sense ;), and
2) Can anyone help me with the code? I've got very little experience working with databases.
