the fields in the tables are all text fields.is there any way to fix this error? perhaps it is in my query but i really cant find a solution.is there an alternative to get what i want my program to do?it is basically entering an ID number and finding the record with the same idnumber and putting the system time on the timein field for that record.
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 have a datagrid with data and I want to update a database with the data on the datagrid.

View 2 RepliesI 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?
View 3 RepliesI'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'm getting a strange syntax error when I run this in VB[code]....
The Username is checked before getting to this part and is definitly in the db. It gives an exception saying syntax error in update statement.
When run my code, I get this error when I try updeting my database:
"Syntax error in UPDATE statement."

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.

i need a update statement to make a record = 1 example : the colum what need to change is active and it must stand on 1 to show you in to a listview (that part works) but i need to do it manualy to make them active now i liked to when the login is a succes then the record = 1 for you this is my code :
Private Sub Button1_Click_1(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim adapt As MySqlDataAdapter
Dim sqlquer = ""
[code].....
i get this error : Object reference not set to an instance of an object.
Protected Sub Button1_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Button1.Click
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.
When i try to save the changes to my database i get the following error. (code is below)
System.Data.OleDb.OleDbException was unhandled

A concurrency violation error? It happens on this statement:

May i know what is going wrong to my Update statement.
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.
