I have a rather perplexing issue. I am using VB.net and SQL for my project.I have a database, to which the connection works. I also have a data table and data adaptor, both of which I know work.I am trying to update something in the database, yet it isn't working. Assume everything listed is declared correctly. What am I doing wrong?
teacher_control_table.Rows(0)("DATA_TeacherLockPasscode") = txtPasscode1.Text
table_adaptor2.Update(teacher_control_table)
That last line throws the following exception:
InvalidOperationException was unhandled. update requires a valid UpdateCommand when passed DataRow collection with modified rows.

View 3 RepliesI keep getting the error shown in the screenshot below.To me it's saying that I haven't established the "UpdateCommand" property for the DataAdapter. However,I have established it as well as the "SelectCommand", "InsertCommand" and "DeleteCommand".All of these are created within a Class Module.I created a Class for the "tblControl" table that is is referencing. This class contains all the properties for this table as well as calls for "inserting", "updating", "selecting" and "deleting" records.I have attached a class.vb file so their is a clearer understanding. The highlighted line of code below is where I'm receiving this error message.[code].....
I'm receiving this message while trying to add a NEW client record as well as a NEW client Address record to the database. This portion works fine. I get the error message when I try to UPDATE the tblControl table with the new ClientID. The below code is where I do the inserts and update.By the way, I actually execute the "control.ControlOleDbCommands()", which establishes the adpControl DataAdapter Commands, when the program starts.[code].....

View 3 RepliesI have a project which contains a large number of lookup tables, and I have all of these lookup tables represented in a single typed DataSet, which contains TableAdapters for each lookup. I've designed an editor for these lookup tables, which should allow editing of one of these at a time. My front-end is written in VB and WinForms, the back-end is a SOAP web service; I can successfully pass the changes to the DataSet back to the web service, but can't find a way to use a TableAdapter to update the single table that has been changed.
What I'm trying to do is instantiate the appropriate TableAdapter for the updated DataTable by sending the name of the table back to the web service along with the DataSet, then referring to the TableAdapter with a dynamic name. The normal way to instantiate a TableAdapter is this:
Dim ta As New dsLookupsTableAdapters.tlkpMyTableTableAdapter
What I'd like to do is this, but of course it doesn't work:
strTableName = "tlkpMyTable"
Dim ta As New dsLookupsTableAdapters(strTableName & "TableAdapter")
Is there any way to achieve this, or am I taking the wrong approach altogether? My other alternative is to write separate code for each table, which I'd prefer to avoid!

Any thoughts on this? Btw, this is my first time using a datarow, and I've recently been studying how to use ADO.net.

I have a problem with the code below as a SQL command string. Note: Using .Net Framework 4.0 in Visual Studio 10 Professional. Database is a Microsoft Access file. The idea is that this SQL command string will update a password within my database. Also note that I have tried the string below with and without the ";" at the end and it does not work either way. The problem is most likely extremely obvious, but I can't seem to find it. I have commented below the code what each part of the String is.
"UPDATE Users SET Password='" & tbx1.Text & "' WHERE Username = '" & sUsername & "';"
' Users is my Table name within the Database.
' Password is the field that I want to edit within the Users table.
' tbx1.Text is where the password is stored within a text box.
' Username is the field which I would like to compare with sUsername which is a variable within the code.
Solution was square brackets, Command string now looks like this:
"UPDATE Users SET [Password]='" & tbx1.Text & "' WHERE [Username]= '" & sUsername & "'"

Currently, users log into a web application with their AD (active directory) credentials which are validated against the AD. Once inside the application, certain users will need to update the AD. When I hardcode a username/password, I am able to update the AD, however when I try to force the object to use the logon credentials or if I don't specify the username/password, it throws an error. Obviously due to security concerns, I do not want to hardcode credentials.

I've got a gridview (ASP.net) inside of an update panel. I also have a "Save" button so that when I click "Save" it loops through all the rows of a grid view and passes the data to a stored procedure to update each row. This was too slow as sometimes I would be updating the database even though a change did not occur.
I decided to add a field in my gridview like so:
<asp:TemplateField>
<ItemTemplate>
<input type="hidden" id="hdnIsChanged" runat="server" />

I have a register.aspx and a login function and i am using vb.net
in my register.aspx...i have a user name textbox and a password text and a submit button. IF the user click on the submit button, the password will be hash and store with the username in the database table called "Customer"
1st Qn: i have a problem is that i never try before hashing, so i not sure how to code it , hopefully if someone got a sample or example to teach me it will be nice
2nd Qn: besides that, in my login function, how am i going to compare the hash value for password that is store in database with the password in the textbox to allow to login?
What i'm trying to do here is login using a table and fields with username and password and also usertype in it. If the user is an Admin then it displays the the command button cmdAdmin and if not admin it disables it. This is the code that i currently have at the moment Hope someone can help me out and also i want to get rid of the username and password that's currently in it and use database instead.?
