View 1 Repliestrying to figure out out to make a combo box re-populate itself with values from its data bindings from an Access database.
I have my bindings in the combo box, and it pulls the right column from my table, and returns the proper value to a different table. Everything saves properly to all of the tables, but what i am trying to accomplish here is this...
I have a combo box, it is populated with a database column of "G/L codes" (by the way that is not the column name) the combo box shows these values without problem.
These codes exist in a table that is editable (basically so the user can add a G/L code to the list if one is missing), a button is supplied that opens a new form, which contains DB related text boxes, and a data binding navigator to look through the data base records, save, add new records, etc. When this form is loaded, the user can add a new record, save the info, and then close this form, which brings us back to the main form where the combo box is located that is populated with the values of this G/L code table, what I am trying to get working is updating this combo box now that a new G/L code has been added.
I have been looking for a solution for days, tried many forums, read all posts on this site that had a keyword of "combo box" and I can still find nothing. I have tried many code samples such as...
Private Sub Repopulate()
Me.G_L_Code___DescriptionComboBox.DataSource = Me.Db1DataSet.GLCodes
Me.G_L_Code___DescriptionComboBox.DisplayMember = "Combined"
Me.G_L_Code___DescriptionComboBox.ValueMember = "Combined"
Me.G_L_Code___DescriptionComboBox.Refresh()
End Sub
have tried calling this when the combo box gets focus in the attempt to update the combo box every time it is selected.
Have tried reloading the table adapter as well when the combo box takes focus with the following
Private Sub G_L_Code___DescriptionComboBox_TakeFocus(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles G_L_Code___DescriptionComboBox.GotFocus
'TODO: This line of code loads data into the 'Db1DataSet.GLCodes' table. You can move, or remove it, as needed.
Me.GLCodesTableAdapter.Fill(Me.Db1DataSet.GLCodes)
End Sub
Honestly I'm at wits end trying to get this combo box to repopulate its values from the database. I don't get any error codes when running either, all my attempts simply do nothing
I'm trying to migrate (mostly mentally at this point) from MS Access to .NET for database programming. I've found one of the first tests to be fairly painful. I'm trying to recreate MS Access's datasheet view in Visual Studio.Features I use in MS Access Datasheet View that I haven't immediately found in the DataGridView I'm assuming that a DataGridView will be used to edit records as opposed to being used as a search/list only.1) Form Level BeforeUpdate Event - Here I typically run validation code2) Textbox level BeforeUpdate Event - If I'm feeling anal I'll run validation code here.

I am using VS2010 and .NET 4. My form has a DataGridView (dgvTest), and a checkbox (CheckBox1). I am selecting 2 or 3 fields from a table, depending on whether the checkbox is checked (which it is initially). My possible SQL statements are "SELECT ID,strForenames,strSurname FROM tblAlumni" and "SELECT strForenames,strSurname FROM tblAlumni".
I have used SQL Profiler to confirm that these are the queries sent to the DB. All seems well when I load the form (I see 3 fields, in the order I expect), and when I uncheck the box (I see 2 fields, in the order I expect). However, when I check it again, the ID field appears THIRD in the columns of the DataGridView, not first! I have found a couple of reports of something similar to this (mis)behaviour on the Net, but folks just seem to find some other way to do the job rather than ask is this a problem with DataGridView that needs fixed.
Imports System.Data.SqlClient
Imports System.Windows.Forms
Imports System

do your experts agree this is a bug? The "fix" is to wipe the DataGridView between repopulations, but I'm not sure I should have to?
dgvTest.DataSource = Nothing
dgvTest.Refresh()
I have a DetailsView1 control that is databound in many fields but also has fields that I prepopulate upon loading the page for the first time. Example being fields named ROW, FLAG, PRINTED. The user can then input data into the other fields Like FIRST NAME, LAST NAME, COMMENTS and press INSERT. I should also mention that these fields are templatefields.
<asp:TemplateFieldHeaderText="Row"SortExpression="Row"><InsertItemTemplate>
<asp:TextBoxID="TextBox1"runat="server"Text='<%#Bind("Row")
%>'></asp:TextBox>
[code]....
Then the insert of the data begins and creates a SQL record. This works as designed the first time thru.The problem begins when I try to populate the same fields for the next record using the same logic that I used the first time but the fields will not come to the screen populated the second time. What do I need to do in order to get the fields in the DataView1 to be populated after the first INSERT command has cycled thru its process?
I can save my data to access database and in the access database field I set it to date/time.But problem is when I get the value out from the database.. the format is always month/day/year hour:minutes:seconds example today: 5/2/2011 12:00:00..How to get the value into listview becoming May/2/2011 without the hour..Here's my code to get it from database ListView1.Items(i).SubItems.Add(dt.Rows(i)(14).ToString).The second problem is.When I would like to edit, how can the datetimepicker get the listview value ?

View 1 RepliesI have two Access database, say database One.mdb and Two.mdb. I want to use VB2005 to export tblCustomer from One.mdb to Two.mdb, and replace the existing tblCustomer in Two.mdb, during run time. I basically want to simulate the export function that is available in MS Access (which can export one table from one Access database to another) with VB2005 during run time. I can think of a way by querying the table to a dataset and then delete everything on the other database before filling the table in that database with the dataset
