What I am trying to do basically is open an access query in a datagrid view and then be able to make changes to the datagrid and then save it back to the database.When I try to save:
Me.BindingSource.EndEdit()
Me.TableAdapter.Update(DataSet)
It says that update is not a member of the tableadapter... Why is that?

I have connected my database to visual basic.I have a form1 which allows me to scroll through all the data in my database (i.e. the name, account no, address etc)My form2 contains a calculation involving payments which involve the previous account.My form3 needs to contain this calculation PLUS the database information in a RichTextBox. My question is how do I include my DB info in a RichTextBox? (i.e how do I pass the information from form1 onto form3)

What SQL Server data type should be used to store RichTextBox text? The reason I ask is because the BOL indicates not to use text or ntext anymore because these data types will be excluded from future versions of SQL Server.

I am very new to programming so let me apologize for that upfront.I am using Visual Studio 2008 and have created a windows application form. I have the form connected to an MS Access database named vendors.accdb. I have added a DataGridView to my form named VendorsDataGridView. I have also added a RichTextBox to my form named RichTextBox1.[code]I have my form setup to run queries that compare like items from different vendors and display them in the VendorsDataGridView.what I need the form to do is when I doubleclick on a particular row (in the VendorsDataGridView) I need it to copy to the RichTextBox1 and go down to the next line so I can add more rows from different queries.I need to understand what goes between the Private Sub and End Sub of this:[code]I could use a textbox instead of a richtextbox if need be.I have searched high and low for the answer to this. I have tried a variety of things but none have worked. I have been reading different books to try and understand Visual Basic code better but I am too new to programming to get the doubleclick event to work.

I have a problem with my datagrid(I am noob sorry if its simple). The datagrid is binded to a data table. What i want do is when a product is added or an existing one changed then make that one the selected row in the datagrid. The SelectionMode of the DataGrid is set for the whole row.
Here is the code that i am currently using,[code...]
Now as you can see from my code i don't understand how the index can be wrong as the datagrid is binded to a datatable and the indexes would be the same, and i have the current row in the datatable and look for the index in the datatable and stored it as a Integer!

I have taken up a task where end user should be able to enter information via vb interface into microsoft Access database. This then will be displayed onto the Datagrid via VB interface. The program needs to be setup in a way that first entry by end user will flash upon 3 hours.
Example:
VB Interface
=========
Basket Number | Number of Trays | Run Type | Time In
1 | 1 | CNC | 15:00:00
[code]....
Values defined within database shows in this datagrid.The Datagrid works fine and I can insert values into the database fine as well however, I am not sure how to setup a timer so that when 3 hours are up the first entry into the database(shown on datagrid) starts flashing.This is needed so that the end user gets an alert when the time is up so that he can take the trays out of the oven.
In Summary: Can we really setup a timmer so that a value in the datagrid will flash at a particular time.Below is the image of an application. Here you can see the data on the datagrid however I want it to flash after 3 hours. So the first entry will flash after 3 hours following the 2nd entry.

I am saving some operational log information into a XML file. At any time the user can bring up a datatable to display the information. I don't want them to see the 'HOURLY' log. I can't seem to filter this out. Also I need to populate a list box with all the unique events for filtering.
Example XML:
Code:
<?xml version="1.0" standalone="yes"?>

I'm writing my very first application for a customer of mine using VB.NET and I'm stuck with this: how can I open an xls file and put it on a datagrid? I've seen it's quite complex but the lack of examples by Microsoft doesn't allow me to do all the things by myself.

I have a datagrid that I am populating from an Access 2000 query in Visual Basic 2008.
This code works fine:
With dgvCollections
.Columns(0).Visible = False
.Columns(1).Width = 235
.Columns(2).Width = 230
.Columns(3).Width = 220
.Columns(4).Width = 70
.Columns(4).HeaderText = "Loan"
End With
The query works fine, except that I want to change the alignment for one of the columns. I tried to add this line before the "End With":
.Columns(4).DefaultCellStyle.Alignment.MiddleCenter()
Which causes the error:
"Access of shared member, constant member, enum member or nested type through an instance; qualifying expression will not be evaluated."
And this error:
"Expression is not a method."

I have populated a dataset with the contents of a csv file. Here is a sample of the imported data:
Protocol,Process ID,Process Name,Local Address,Local Port,Remote Address,Remote Port,Status
TCP,4,SYSTEM,134.190.220.54,4505,134.190.184.193,139,ESTABLISHED
TCP,4,SYSTEM,134.190.220.54,3963,134.190.218.5,139,ESTABLISHED
TCP,4,SYSTEM,134.190.220.54,3816,134.190.176.154,445,ESTABLISHED
Here is the code that I used to import and display the data:
Code:
Dim sConnectionString2 As String
sConnectionString2 = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" _
& CasePath & ";Extended Properties=""text;HDR=Yes;FMT=Delimited"""
[code]....
The problem is, all of the data gets displayed correctly except for the ip address. It gets truncated to "134.1892". How can I change the formatting for the "Local Address" and "Remote Address" columns.

I am building an application that has several forms to it and on my first form, I declare 2 variables that I will need to pass to at least 2 of the other forms. I call them
Public payPeriodStartDate, payPeriodEndDate As Date
on form2, I am needing to pass those variables to a datagridview to present to users. I have the following query that I'm trying to run from that form but I'm given an error that SQL is unable to parse the query:
Code:
SELECT Employeenumber, Exceptiondate, Starttime, Endtime, Duration, Code, Approvedby
FROM Exceptions
where [Exceptions].exceptiondate between '" & payperiodStartDate & "' and '" & payPeriodEndDate"
The datagrid is bound to the form and I'm using SQL 2000.

My text file is something like what you see below, and I want to populate the datagrid. Once I populate the datagrid, I'll use that kind of like an excel spreadsheet in the sense that I'll dip in and grab values based on row and column index to display to the user. I will also (on a different form maybe) display the same datagrid to the users so they can sort by column at their choosing.[code]The error I am getting is: Value of type 'Integer' cannot be converted to 'System.Windows.Forms.DataGridViewCell'.

I am using Visual Basic 2008, and SQL Server 2005. I have a single-user client-server app (i know that sounds stupid, but its for future expandibility and also the fact that documentation was easier to find for SQL server than Access files).The app is basically a medicals records system.
In one of the tables, called 'visits', it stores the dates on which each patient visits the doctor, among other things like symptoms and diagnosis. Another table stores all the patient names and IDs along with other details, and a relation has been set up between the patient ID in the patients table and the visits table. So i dragged the visits table from within the patients table (to get only the visits for that particular patient), and dragged it onto the form to make a datagridview. However, the datagridview didn't seem to recognise MS SQL server's smalldatetime format, and tried representing it as a picture. When i changed the format of the column to text boxes, it gave me a type mismatch error (Inconvertible type mismatch between SourceColumn 'VisitDate' of DateTime and the DataColumn 'VisitDate' of Byte[].) That means, for some reason, it is trying to convert the smalldatetime data to byte before it shows it, which is leading to the error. How do i fix this?
Also, I remember seeing some option for using completely custom column types in the datagridview, but i cant seem to find it now. The options in 'Edit Columns' are very limited, but i would like to set it to a masked text box, or something with a fixed format. Can someone recommend a good column type for representing dates, and how to make the datagridview show that kinda column?

I have a 'DataGrid' usercontrol on my simple little form and I press a button that opens a text file and populates the DataGrid like so,
A B C
1 2 3
3 4 4
3 1 3
Where A, B, and C are my column headers.
I also have a 'ListBox' on the form. What I would like to do is, allow the user to select one, two, or three rows (or all) in the datagrid, and press a button that will move the data from selected rows into my listbox (each row its own string in the list box).
I can populate the datagrib easy enough, but don't know how to access the cell data individually?
