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?
how to retrieve image from access database?.. I've just finish retrieving data to the datagrid view. I want to retrieve also the image (also stored in the database as path inside the table where the data stored) in the picturebox. When i clicked the specific data in datagrid view, it will show preferred image to picturebox.
View 1 RepliesI'm currently attempting to save data inputed into a data grid clicking the "save" button. My problem is, I also have another DB opened in the same window that also needs to be saved. The second database is pulled up by the contents of a text box, so there for it has no real Dataset to call on. It looks something like this.
[Code]...
I try to run the update command it always throws the exception "Cannot find table 0" or "Update unable to find TableMapping['Table'] or DataTable 'Table'." I tried declaring the connection the same way as the code above and then simply calling the da.update(ds) but it wouldn't do anything.

View 1 RepliesI 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.
I have two text box(Start Value and End Value), one datagridview and a search button SQL script= Select id, ContactName from Customers where id between 1 and 5 I want a scenario where when I enter the start value 1 and end value 5 and click the search button it will run the above query and display the result in the datagrid view.
View 4 RepliesI decided to rewrite my project. Hit another snag. How do I write the contents from a datagrid to a file and back into the datagrid again later? (Actually, I've done the writing ok - but for the life of me can't get the data back into a blank datagrid.
Here's what I done so far:

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.
View 3 RepliesI 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?

View 3 RepliesI 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 use visual basic 2010 professional edition. I am working on a project on it with access on the backhand. i want to view the data in datagrid control for the stock management.

But when i click somewhere else, an error appears which says: Data type error in expression.

View 1 RepliesI am new to VB.net and attempting to write a small program as a learning exercise. I am writing a simple clock in/clock out time type of program where on Form 1 a button is clicked to clock in, then a button is pressed to clock out. When the clock in button is pressed the date and time captured and shown in a label 1. The clock out button places the date and time in a label 2. Label 3 shows the elapsed time between clocking in and out. I also have a label 4 which keeps on adding elapsed times (user may clock in and out several times) to show total time worked. All of this works fine.
I have made a dataset and datagrid on Form 2 to store all of the clock ins and clock outs. I have a history button on form 1 which takes the user to form 2 where the history can be viewed in the datagrid. I cannot figure out how to send data to the data grid from form 1. I thought the simplest way would be to place the value of label 1 in the first column of the datagrid, the value of label 2 in the 2nd column and the value of label 3 in the third column. Then when the process is repeated the values will be entered into row 2 of the datagrid and so on.
How to make query from mutiple datagrid so that the data from datagrid will create chart?
View 10 RepliesI started a forms solution in VB 2008, created a datasource to an access database (2010) and used the datagrid view to display the data. 3 fields in the access database are lookup fields with 2-8 values each, typed in by me, since the linking to other fields did not work. This is not working either. When I change the column to combo-box or not, those values, typed into access, are NOT showing up in the datagrid. the combo box has its drop down arrow but the value fields are empty.

Visual Studio 2010, Visual Basic I am able to import a .csv file into a datagridview on my windows form using the code below:
Private Sub Button1_Click(sender As System.Object, e As System.EventArgs) Handles btnChooseList.Click
Dim fName As String = ""
OpenFileDialog1.InitialDirectory = "c:desktop"
[code]....
My issue is that I can get the .csv data into the datagridview, but I need the user to be able to indicate which column is the "First Name", "Last Name", "Address", etc so that I can add the data to the correct column in the database. The imported lists won't always be in the same column order.The end result needs to be that the data in my datagridview will be altered by the user and then saved to the correct columns in my database.
