View 1 RepliesForms :: Using Update With A Table Adapter?
Feb 21, 2011I have a form that has a datagridview and a table adapter that displays data from a SQL database. What I'd like to do is that when edits are made to the data in the datagrid, I'd like to post all of the data back to the table. I know that you can do that with a dataset and a data adapter, but I don't know how to do that with a table adapter. Here is the code for my page:
Public Class ExceptionEdit
Private Sub ExceptionEdit_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
'TODO: This line of code loads data into the 'MDRDataSet.scratchpad3' table. You can move, or remove it, as needed.

When people click on the Save Exception button, I'd like to save back to the update the database with the new data.
Update Using Table Adapter - "Update Statement Conflicted With Foreign Key Constaint....."
Apr 5, 2010I have a form with comboboxes, if the user doesnt select a value in the box I want a null to be sent to the database. The insert works fine, i look at the record in the db and see the null. The update doesnt work. gives me a n "Update statement conflicted with foreign key constaint....."
Public Sub Update()
TableAdapterCreate().Update(ID1, ID2, CType(cbox1.SelectedValue, Integer), CType(cbox2.SelectedValue, Integer), CType(cbox3.SelectedValue, Integer), CType(cbox4.SelectedValue, Integer),
[CODE]...
As I step through the selected value of the cbox 5 is shown as nothing (which it should be because the user didnt select a value for this combobox). I assume this needs to be a null instead of nothing to get written to the database. the combox boxes need to match a primary key in another table so sending a 0 would also result in the forieign key error since the related table does not have a 0 ID field.
Table Adapter InvalidCastException When Attempting To Update Through Column Headings
Feb 17, 2011As the title says, when I attempt to update a row in a table in a database, I recieve an InvalidCastException. I am unsure why, since the variables I am using should be, and indeed, when I check them at runtime, are filled with the correct data.
I am trying to update using the method wherein the row that is being updated is identified with all the variables already stored. Interestingly, Intellisense is telling me that EntryID, the primary key, is only necessary in it's original form, and that the variables that I am attempting to update have question marks after their type.

Append Multiple Rows In A SQL Database Table With Primary Key?
Aug 9, 2011I am trying to append multiple rows in a SQL Server.I have connected to the MS SQL Server and with a DataAdapter, I have downloaded the Table into a DataTable and displayed it in DataGridView.I now want to programatically enter multiple rows into the DataTable and later to update the SQL Table.
I am trying to build an application to do this generically.The problem I have is that the Table and DataTable has an 'ID' Field. In the SQL DB, i is an Auto-incrementing field.When the code loops through creating new rows and entering field values, how do I handle the ID Field that is the Primary Key?
Retrieve Primary Adapter's IP Address?
Feb 2, 2012The following code will list all IP addresses of each adapter on your system:
Imports System.Net
For Each IPAddress In Dns.GetHostAddresses(Dns.GetHostName)
Debug.Print(IPAddress.ToString)
Next IPAddress
How can determine which is my primary Windows adapter? ie: Running the above gives me:
fe80::c78:d30:ce6c:67cb%10
fe80::f823:5811:6404:f6d3%21
fe80::94bc:17f:5cd9:4a1%26
[code].....
My address from my router (primary address) is 192.168.1.25, or also it would be Dns.GetHostAddress(Dns.GetHostName).GetValue(4) which is the 5th element in the array If I'm obtaining a users local IP address on various machines with various amounts of network adapters, my program will break. I must know the IP of the primary Windows Ethernet/Wireless adapter in use.
Retrieve Primary Adapter's Gateway Address?
Feb 6, 2012I managed to obtain the primary adapter's IP address here: [URL]
But now I need that adapters gateway, ie: 192.168.1.1

View 12 RepliesVS 2008 Update Table And Ignore The Missing Columns Using The Single Dataset?
Jul 5, 2011How can i do a workaround for this? I two databases(.sdf). Database A has table A1 Database B has table A2 Table A1 is an exact duplicate of A2 minus 3 columns My dataset(.xsd) is based off of tableA2 in Database B. I can fill all my tableadapters in Database A and all info in table A1 using the dataset. My problem lies when I do TableAdapter.Update() for Table A1(Since the dataset has the 3 missing fields) it tries to update table A1 with info that isn't there and I get an error. How can I update table A1 and ignore the 3 missing columns using the single dataset? Or is TableAdapter.Update() designed to Update the Database with all columns found in the dataset ?

Oct 6, 2010I have a windows form program that pulls data from a sql server. That same data is being read from a ASP.NET website that sets properties for the site. The SQL server has 3 tables: tblWebPage, tblObjects, tblProperties. and 6 views for the 6 web page: vWebPage01, vWebPage02, vWebPage03..ect. When the program loads you see buttons for each web page on the site. When the user clicks on the Home Page it loads this data: [code]Now, the problem lies in updating vWebPage02, vWebPage03, ect.. I assume with the same data I can copy my form with the code and change the form name and the data set to build and update. So that's just what I did changed the form name where needed and changed "vWebPage01" to "vWebPage02".When I tested the program My "vWebPage01" form it built and updated no problem. when I went to test "vWebPage02" it built the dataset and table adapter fine but it did not update at all.

View 1 RepliesDatagrid And Queries With Multiple Joins To Update A Table
Jan 19, 2010We use an ERP program in conjuction with SQL server and lots of tables that keep track of product records customers and all these kinds of stuff. I am building a fairly simple Warehouse Inventory Application that warehouse employees will use to count and inventory stock on hand from products around the warehouse and then check if any quantity errors occur between stock on hand and logistic quantities.I have created a custom Inventory table that I would populate with records like {stock_code, Description, Quantity_remain, quantity_avail}. Those records already exist in 2 different tables in my database. The aim is that I want my program to fetch daily 10 random codes from the stck table, and records about their quantities,bringing together the "columns" that my new custom table has +2 more editable columns: inventory, date, user with a query like this:[code]
As you can imagine my custom table contains the exact same fields as the query suggests + 3 more.I use the the stck table to fetch product info like its code,description, its group_code, categ_code, and then I outer join the stck_x_th that contains records concerning quantities remaining or available asociated with each product code and the "places" those quantities reside in the warehouse.Then, store them in a datagridview control, with only one editable column -inventory- (user and date columns are auto-populated with default values), and then when the user fills out the inventory quantites, I want to save the datagrid "as it is" in my new custom table.I am creating a databound gridview control using one table adapter (which refers to the inventory table). Then I add to my table adapter using "add query" the forementioned query with a fillby method to populate the Datagrid (and therefore my Table in SQL) with the exact same values my query returned from the different tables. But whenever I try to update the table concurrency exceptions raise.It works like a charm if I enter the values in the grid cells manually, without populating the grid control with the new fillby method my self but not if I populate the grid via a query and then hit update.

Use SQL To Search Multiple Tables And Columns For Search Function?
Aug 23, 2009Im making a search function for an application and they need to be able to search by any value in the DB in any of the three tables. Im wondering the best wayto about this. 2 of the 3 tables have the same columns while the last one is totally different. Below is what I kinda "thought" itd look like but no.
"SELECT * FROM cases, opencases, staff WHERE Crime ='" & txtsearch.Text.ToString & "'"
I need to query the results the user can search for anyterm and if it matches something in the columns it return it to the user. Im wondering if the best way to go about this is to maybe query all the tables and then put all the matching records in a seperate table and the dgv look at that table or how to exactly go about it.

Way To Create Empty Data Table / Update Its Contents Based On Columns Not Add Data Based On Addition Of New Rows
Apr 6, 2011I am creating a project in VB.NET in which one of the reports require that the name of employees should be displayed as column names and whatever work they have done for a stated period should appear in rows below that particular column.Now as it is clear, the columns will have to be added at runtime. Am using an ODBC Data source to populate the grid. Also since a loop will have to be done to find out the work done by employees individually, so the number of rows under one column might be less or more than the rows in the next column.Is there a way to create an empty data table and then update its contents based on columns and not add data based on addition of new rows.
