Using The UPDATE Statement?
Apr 16, 2009
I have a datagrid with data and I want to update a database with the data on the datagrid. I only want to update one column, the problem I have it is that the Column it is name diffrent on the datagrid than the database. On the datagird it is name "EloBirdFinal" and on the database it is name "EloBird". I did some code but it didn't work. I will put my code here
Dim RowCount As Integer = DataGridView1.Rows.Count - 1
Dim ColumnCount As Integer = DataGridView1.Columns.Count - 1
Dim RowIndex, ColumnIndex As Integer
[code]....

I 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.

I currently have a problem attepting to update a record within my database. I have a webpage that displays in text boxes a users details, these details are taken from the session upon login. The aim is to update the details when the user overwrites the current text in the text boxes.I have a function that runs when the user clicks the 'Save Details' button and it appears to work, as i have tested for number of rows affected and it outputs 1. However,when checking the database, the record has not been updated and I am unsure as to why.I've have checked the SQL statement that is being processed by displaying it as a label and it looks as so:
UPDATE [users]
SET [email] = @email,
[firstname] = @firstname,

I'm trying to update a specific record based off of a users selection. Regarding Entity Framework syntax, I'm not very familiar. Is it possible to achieve this SQL statement in Entity FrameWork?

I'm trying to refresh the datagrid after using the SQL UPDATE statement. The data changes physically in the database but the datagrid is not affected. The data is changed only after i restart the program.
How can i get the datagrid to refresh or update? I have tried using, among other code, the refresh() method, but it does not work.

I have the following code which works fine;
For Each myFile As String In IO.Directory.GetFiles(Label1.Text, "*.zip")
Dim fi As New System.IO.FileInfo(myFile)
sFilename = fi.Name
Col_Prac_no = sFilename.Substring(1, sFilename.IndexOf("_") - 1)
For example: I have filename as:
I00018_20120329042035_111
The col_prac_no = 00018
Now, I want to update the for statement to have another value extracted from the filename.
The first letter of the filename. In the example:
I00018_20120329042035_111
The first letter of the filename in above example is I.
So if we have:
S00018_20120329042035_192
the value will be - S.

Dim s As New Staff
[Code]....
Basically I am trying to update each record with 2 random numbers each time the button was clicked,my problem now is, the system will update the record but the data was wrong. Example, by right all data should be different (randomly string) but for some row it was updated with same data but in randomly, something row1 row2 row3 has exactly same data for column 1 and 2 then row 3 has distinct data, second time, row1 row2 same data row3 ro4 with different data. It is in random sequence. When I add a MsgBox to do testing in the For loop the data was updated correctly with all different data.

A concurrency violation error? It happens on this statement:
CODE:
It thinks I'm using a key value of 1 when the actual value is really 1218. I'm using a command builder. The attachments show the value of the key value and the value of the update text values. By the way, I can insert data but not update it.

Attempting to run an SQL statement to UPDATE a column in a table with new data. The column being updated is defined as varchar(40) and the new data is 41 bytes (varchar(41)). I get a generic 'data will be truncated' error message, but no detail on which column caused the problem. I've attached a sample VB program to illustrate the issue. In this scenario, Company is defined as varchar(40).
My question: Can I get a more detailed error message? i.e. can I get an error message that tells me the row and column that the truncation occurs in? Often times, I may be updating hundreds or thousands of rows and only one value in one column from the source file is too large for a database cell. As a related question, does each OLEDB provider create its own error messages. i.e. will the MS SQL Server OLEDB provider potentially give different text in the error message than say the MS Jet OLEDB provider?

I am creating a form that is able to update data in SQL server after selecting an MS Access file (.mdb). I am having an issue where the data has a single quote ('). I found out that the solution was to use Replace() - to replace the single quote with two single quotes - Replace(string, "'", "''").Now, for some reason, I am getting an error "Conversion from type DBNull to type String is not valid." Here is the code.
cmd = New SqlCommand("Update Child Set " & _

I'm trying to update a row via c# winform application. The update query generated from the application is formatted correctly. I tested it in the sql server environment, it worked well. When i run it from the application i get 0 rows updated.Here is the snippet that generates the update statement using reflection - don't try to figure it out. Carry on reading after the code portion:
public void Update(int cusID)
{
SqlCommand objSqlCommand = new SqlCommand();
Customer cust = new Customer();
[code]....
The above final update statement works on the sql environment, but when running via the application, the execute non query runs ok and gets 0 rows updated!

It seems like a lot of people are having trouble with this piece of the control toolkit.I've looked for a few days on the internet for an answer and haven't been able to find one. Best solution I've seen so far is "write your own reordering procedure" which I don't want to do.

</asp:ScriptManager>
<asp:UpdatePanel ID="uPanelReorderList" runat="server"
