DB/Reporting :: How To Save / Load Info In DataGridView
Nov 30, 2009
I'm working on a simple "sports management" game just to test out whether I could make an actual one some time in the future, but for the life of me I haven't been able to figure out how to save the contents of the datagridview. I want it to be saved in a format that doesn't require the user to have Access or any other program, so that the only thing users need are the .exe and the database file. Another question about the datagridview: How do I access the content on specific rows and columns of the datagridview? If I want TextBox1.Text to be whatever is written on Row 4, Column 2, how do I access that information?

I currently have a vb browser and cant for the life of me find out how to load a "favorites list" the furthest I've got is add text to link label and save text in a location. I also cant find an if statement stating that if a label has type in it you move to next label.
Code:
Private Sub Favourites_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Dim savef As New System.IO.StreamWriter("c:Program FilesAmaza Browserfavourite links.txt")

I have a datagrid bound to a datatable. The datatable will then be written to an xml file using the built in "WriteXML" function, which is sweet!
What I would like to do is update the table then overrite the existing XMl file when a cell value changes.
The problem is the "CellValueChanged" event is fired before changes are actually committed to the dataset. I do not want to use the "CellValidated" event because it will fire for each row when the file is forst loaded into the dataset and displayed in the datagrid.

I have a form that has around 4 txtboxes. Data is inserted into these boxes and then a "Save" Button is pressed. I have a GridView added to my form and want to view the entries. The issue I am having is that when I click the save button the data doesn't show up in the DataGridView until I close the application and then re open it.

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 I am trying to do is get specific info from a database and what I am getting is the first entry.
I have made a database connection, made the top bar not visible and I have inserted a text box and multiple labels. My MDB database has 3 columns (street, city, postcode) and multiple rows.
What I want is when a user enters a postcode in the text field the other labels get the info related to it. I.E. when a user enters "FY1 3DL" the labels update to "King street" and "Blackpool". With the code below I get the first row from the database.
Code:
Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click
Me.StreetsTableAdapter.Fill(Me.WcipcodeDataSet.Streets)
End Sub

I need to convert a large VB6 app to vb.net which does a lot of database work and produces a Crystal Report. The initial form is simple a login form which validates the user. I am trying to use a datareader to retrieve the user's login info but it won't compile on the statement where I'm trying to get the Connection String from the app.config file. It complains that the ConfigurationManager is not declared on the dim statement. Where and how do I declare the ConfigurationManager? I thought it was just pointing to the app.config file but apparently that is not correct. [Code]

I'm writing a program in VB.Net and loading the info into a SQL database. Debugging it works fine on my machine that I am programming it on, it connects to the database and runs through all the info perfectly. However trying to get it to run on another machine it will not connect to the database. I realize the reason for this is the connection string, it's looking specifically at the file directory for the database. How do I change this so that it will function on any machine. The program is only intended to run on one machine at a time and not over the internet.

I need to write some code to tell the user when daylight savings starts and ends in another timezone, this is what I came up with but it keeps selecting the last Else line. The other lines are working fine, the problem is only with the lines, daylight savings today and not tomorrow. There is probably a much neater way of doing this but I thought this would work.
Private Sub Auto_Time_Change()
Dim sydneyTime As TimeZoneInfo = (TimeZoneInfo.FindSystemTimeZoneById("AUS Eastern Standard Time"))
If TSSlblTimeZone.Text = "Normal Time" Then
If CurDate.AddDays(1).Day = "1" Then

How do I get my info from a .txt from my website to load into my listbox?! Like if I were to do this...
Try
Dim client As New Net.WebClient
client.Credentials = New Net.NetworkCredential("username", "password")
ListBox1.Items.Add(client.DownloadString("ftp:public_html/listboxitems.txt"))
Catch ex As Exception
MsgBox("Error : " + ErrorToString(), MsgBoxStyle.Critical)
End Try
It just adds a straight line of my multi lines that are in the .txt file...

I'm new to Comma Delimited values. What I'm trying to do is load up a text file which has employee info separated with commas
like 1/1/09, John Smith, (555) 555-5555, 101 S 1st Street and has numerous rows of info like this
so what I want it to do is just write this info to 4 different textboxes
like txtdate would just have all the dates of employees listed in rows or multilines
then another text box for names and so on.. Right now I just have it all being written to one text box.
I'm not sure how to separate all the information accordingly.

where can I find information on how to take info from a text box and save it to a file and later retrieve the info and print it out on a printer or back into text boxes? Also creating a database.Example. The Database will contain a list of customers. Within each customer profile there could be any number of databases for just that customer. and with in each database there is a system to keep track of different things.
Main Database = List of different Customers
Customer Data Base = List of different key systems.
Customer database key systems = list of key generated and if the have used that number or not. (Along with other info)
Where is a good place to start.
Basic File saving to complex file saving.

I have a gridview with four template fields that I need to be able to put info into to save to the database. When I hit the edit button and my columns change into edit mode I can enter information just fine. But when I try to loop through the control to get the information it doesn't pick anything up?
Private Sub gvOLIAdj_RowEditing(sender As Object, e As System.Web.UI.WebControls.GridViewEditEventArgs) Handles gvOLIAdjst.RowEditing
gvOLIAdjst.EditIndex = e.NewEditIndex
BindData()
End Sub
Here is the update event that I have so far... any ideas? Am I just not doing this right?
Private Sub gvOLIAdj_RowUpdating(sender As Object, e As System.Web.UI.WebControls.GridViewUpdateEventArgs) Handles gvOLIAdjst.RowUpdating
Dim dts As DataTable = DirectCast(Session("BudgetsTable"), DataTable)
Dim row As GridViewRow = gvOLIAdjst.Rows(e.RowIndex)

Okay I'm making a song organizer and I have a program that will load the files in a folder into a box and display the songs info into a list view. That part works fine but when you click the button to make it do anything it will get the variables that it need from the tags on the cells for each song but for some reason the one for the Album just disappears... I tried having it just show the value in a message box and it works fine. Just when I try to combine it with another variable then it wont show at all. Heres my code

I have a DataGridView (dgv) on a Windows form (VB.NET) which is bound to a datatable. One of the bound columns is a an ID (Foreign Key) to another datatable. All I want to do is Hide the ID column and populate an unbound column with the Name (ParmName) for the user. I searched the foreign value in the datatable and retrieved the information. I set the Value of the cell in the Datarow. All works well, but does not display. The cell accepts the value...I can even Debug.Print the values to the console. They are there just nothing displaying in DataGridView. Nothing odd about DataGridView. Should be straight forward...
My Code
,
Dim dtParm As DataTable = MyDataSet.tblParameter
Dim dgv As DataGridView = Me.dgvResultNum_DataGrid

Is there a way to save all info for a button on onw line of text.example:
txtbtnInfo = Button1.ToString
I will then save txtbtnInfo to a settings file. Then when the form loads reset the button with
Button1 = txtbtnInfo
I have an app were the user can edit the size, color, and text of a button and I am hoping for an easy way to save this infomation. I am now saving the properties separately.
