Text Box Not Displaying Data From Table?
Dec 13, 2010
I have a textbox which is part of my program and when I input data to the text box it fills the database with the data the way it is supposed to. I navigate through the data and the textbox show all the data from all the records I input. The problem is when I close the program and reopen it the textbox is empty for the first record. When I run a report or look at the access data base the data is there. If i navigate and go to the second record it shows the data for second and all the others the way it supposed to in the textbox.

I found a sample of how to display data from a table in to a datagrid using VB.
con.Open()
Dim reader As SqlDataReader = _
cmd.ExecuteReader()
DataGrid1.DataSource = (reader.GetSchemaTable())
reader.Close()
But this just displays the details of the table columns. For example row 1 has details about usrID, row 2 usrTel ect rather than the actual data of the table.

Data table information: Data Source = Login.accdb, Data table = LoginTable, Connection = LoginCn. I use visual basic 2010. So how do I do this?

A simple database has been created in Access, which is just basically a table of text, with some images as entries. A form has been created in VB2008 Express and linked to the database. Either a combibox, text boxes or pictureboxes are linked to a column form the database. The first row entries are all displayed correctly in the relavant boxes (except for the images, which for some reason aren't displayed). If another value in the comibox is selected, the other box values don't change and there is still no images visible...

I am using vb.net in my project. I have a datagridview bounded to a datatable m_table which has a column called Price_Change with decimal values. I want to display text in datagridview in green if price change>0 and red otherwise. I cannot simply use the following formatting because the bounded data table m_table is constructed in my code, not directly through data base.
DataGridView.Rows(0)Cells(0).Style.ForeColor=COLOR.BLACK
Code looks like
Dim rowText As DataRow = m_table.NewRow
rowText("Price Change")=10.00 'assign values to price change column
' there is no color formating for data table I wonder if cellformatting event can be used for this purpose. Would it slow down the load of datagridview? [URL]

I am trying to bind data from a text box on my form to a field in my database table. First of all I have created a DataSet, BindingSource and Table Adapter in the forms Design view, but I am having from there. Under the properties of each text box I have set the DataBindings (Text) to the field in the table under the forms instance and DataSet rather than the Projects Data Sources. I am very rusty at Visual Studio 2005 and that is all I have to work with.

I'm building a program in which it asks for your name and age and determines a ticket price based upon these details. I want it to show the person's name, then their age, (jump down a line) then their ticket price, and then it jumps down a line to show the next person's name, age and ticket price. Issue is, when it's meant to jump down to show the next person, it just completely deletes the last person's details.I'm using this line of code:
TxtFareShow.Text = (Name & Age & vbCrLf & Price) & vbCrLf
How do I fix this?

I have a table and I want to select a field in it and then display it in a text box
something like:
SELECT userName
FROM userTable
WHERE (userLogged = 'ON')
how can I display the selected username in a textbox?
BTW the userLogged indicates wether the user is logged in or not
if the user is logged in then the userLogged will be changed to "ON"
if the user is not logged in it will be "OFF"
I know it's not that practical but I'm still practicing.
I'm using Visual Web Developer 2008 Express I use table adapter procedures for querying

I'm trying to make a way for them to export orders to a .rtf file. In order to preserve formatting (bold, underline, etc.), I'm creating a RichTextBox (through code) and formatting the text appropriately. To save the output, I'm simply using the RichTextBox.SaveFile method. Now, to list all of the products that were sold in the order, I'm deriving the information from a ListView. The ListView contains the product name, product price, and quantity sold of that product. I cannot find a way to list the output in a table-like structure, so I tried making a DataGridView and pasting it onto the RichTextBox. Unfortunately, this didn't work at all, so I was wondering if anyone had any ideas as to what I can do. I can't simply use Tabs to space out the information because it doesn't get formatted nicely.

I just starting coding in VB.net about two weeks ago so I'm still a begging and I learn best by seeing working code and then adapting it to my situation. That being said, I need help displaying table entries in a listbox. I've successfully created a database in my test application, added it to my Data Sources and used a drag / drop method to add Datagrid View & Details (labels & textboxes) to my application for testing purposes. Now I want to try and display table entries in a listbox.
Example Database:Table: Contact
- ContactID (autonumber) [primary key]
- FirstName (text 50 limit[code]....
Also is there any benefit or down side to creating a database in MS Access, create the relationships & tables, then attaching that database to my application or is it better to create the database in the application like I did in the example above by using the Add New - Service-Based Database option?

I have a table in a databases that contains 12 rows. I am loading a runtime dataset with that table. The result are displayed on 2 different controls. The first one is a DataRepeater and the second one is a DataGridView. The DataGridView displays all 12 rows just fine.
The DataRepeater does not. Some of the 12 rows will be blank and some will have the data. Sometimes I won't see any data until I completely cycle the scroll bar to the end and then back and still some of the 12 rows will be blank.

I've been writing a weight program for flooded pressure vessels and I'm having trouble retrieving the data from the text files I've been saving. I know how to write the data to the text file, but retrieving it with OpenFileDialog is not so easy for me.The user has individual text boxes that they input strings or numbers into and when they save the file, each text box input is written to one line in the text file. For example, the first text box is for the username, therefore the first line of text that is saved is the person's name, the second text box is the customer, thus the second line in the text file is the customer name, and so on.
(Actually, the first line of text in the saved file designates whether English units were used or Metric units because when the user retrieves the saved file, English units will open one form and Metric units will open a separate form, so some If...Then statement will need to occur).I need to be able to read the first line, have either my "EnglishForm"form open or my "MetricForm" form open, and then have each subsequent line of text be displayed in their corresponding text boxes. I know I need to use ReadLine or LineInput, but I don't have a clue what to do.Assuming the syntax I've displayed below would just magically work (if only life were that easy), it would look something like this
If FirstLineOfTextInFile = "English" Then
EnglishForm.Show()
ElseIf FirstLineOfTextInFile = "Metric" Then[code]....
And so on...I read a lot of articles from the MSDN library and exhausted each link that I've looked through from Google and Bing, but most only retrieve data from the file to a single text box through some loop or streamreader and don't take into account multiple forms.

I want it so every time I click an ITEM in the Listbox it displays ALL the data into the textbox. I know there's an easy way using table adapters and binding the listbox, but I'd prefer to do it this way for my project.
So this is what I got.
Lst.DataSource = ds
Lst.DisplayMember = "tblStudent.FirstName"
Lst.ValueMember = "tblStudent.StudentID"
[code]....
It only adds the first rows details to the text box when I click the second record the first rows details are still there.

I used following code searching records from a table in MsAccess and displaying in a Listview and it is working fine with the search criteria based on Discription.
CODE:
I also tried the above code to search records on the base of CustId and it worked fine too.My table DailyTransaction in MsAccess is as under:DTDate, DTTime, CustId, Description, Quantity, Price, Amount, AccountNumber, Name
Now I want to Search records on the base of Date I tried the following but it did not work.
Dim cmdText As String = "SELECT * FROM DailyTransaction WHERE DTDate=' " & TextBox1.Text & " ' "
Also i want to make following sort of query to retrieve data between two dates and to display the sum of amount group by DTDate. I could sketch following query and deifinitely it is so wrong with Syntex.Select * From DailyTransaction where DTDate Between textbox1.text AND textbox2.text Group By DTDate AND SUM(Amount)
