Hello everyone...
Just for the record, I'm a newbie to this data binding thing... In my
C# application I need to bind a cell of an Access database table to a
multiline TextBox. How should I do it?
I've tried to bind the TextBox using the VS IDE (which ended up in
binding to a table column). This was perfect until I used the Update
command. Then an exception was thrown, telling me, that to update a
database it needs to have a DataRow collection of changed rows. Anyone
familiar with this?
The content of the first cell of the column is displayed correctly in
the TextBox. Any other cell filled with data is ignored (I don't see
that as a problem, because I'm interested in viewing and editing of the
first row of the first column only).
Is there a way how to bind the particular cell to a TextBox?
I'm missing something here for sure. Binding of a database to a
DataGridView and its updating is not a problem for me.
Any advice or pointers how to do the desired thing would be
appreciated.

You need to check your update statment, it seems you are trying to update
multible rows at the same time.
thank you.

Thank you very much for your reply... I'll look at it. Maybe there is a
problem with VS IDE and it doesn't set the update command correctly
when binding TextBoxes using the Wizard...

Solved... VS IDE somehow forgot to create methods Update, Insert and
Delete plus a few other things in DataSet Designer file...

Does anyone knwo how I can bind a textbox to a single dataset/dataTable row?
The following will give me only a Column:
textBox1.DataBindings.Add(new System.Windows.Forms.Binding("Text",
this.myDataTable, "TableNaam"))
But in my program I need a textbox (that I can edit) directly bound to a
fixed cel in a Dataset/ dataTable.

Hi, All,
Is it possible to access a variable inside of a data binding, without the
variable being out of scope?
(Note: On the DataBinder line, I get an error message that says "Name 'i' is
not declared". The data bind is for a DataList.)

Hello,
I have an Access Data Access Page which has a pivot table. The data source of the pivot table is a SQL database table. The data in the pivot table itself is not a problem.
I have a text box below the pivot table. Let's say the pivot table has: First Name, Last Name, and Address. When I click on a record in the pivot table, I want the Address for that selected record to be displayed in the textbox below.

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
Here is my compilation command:
