I have two table called
1.Register product table
2.Sell product table
Register product table consist of (Product Id (txtProdId.text) and Product Name(txtProdName.text)) NB. All are textboxes Sell product table consist of (Product Name(cboProdName.text) and ProdPrice (txtProdCost.text)). NB. ProductName over here is a combobox.
When someone saves record in the Register product table, items should be added into the combobox into Sell product table.
I have an access database with a couple of tables (each with a couple of fields).
in the vb form i have databindsource for two tables each table's fields are shown in textboxes (whose displaymember has been set to each field).
I tried adding a new row to the table like this:
Mbindingsource1.addnew()
textbox1.text="df"
textbox2.text="tttt"
me.Mbindingsource1adapter.update(me.missiondataset.Mtable)
I don't get it, it works just fine for one table but doesn't work for the other which simply doesn't add anything.
I am already exporting datagridview to ms excel and I need to add a row for "Total" but I've encountered a problem because I don't know how to merge the cells for my "Total" since the code for that is placed in a for-loop, there is no exact cells to be assigned for "Total" because it depends on the number of rows in the table. As a result, "Total" is placed in each cell in a row at the end of the table.

How do I do this for a different dataset? I'm trying to rule out database problems so I made another one and added it, but now I need a table adapter for this one instead of the old database because it keeps giving me an error. I don't see any place to add them and I'm getting extremely angry at these databases.

I have already binded a data source from Access to my visual basic program but need to add a True/False column to two of the tables. I could do this manually in access and re-bind the sources but that would take up too much of my time so I wanted to know if I'm using the proper code to add a column to the data table directly from VB? Here is the code I want to try but I don't know where to place it?
OleDbCommand = OleDbCommand("ALTER TABLE tableName ADD
FieldName DataType");
(something).Connection = OleDbConnection;

I'm not sure what goes into the "something" parenthesis and where this code must go. I already tried editting through the data designer but although it shows the column in the DataGridView, it does not save any data or the column into the actual access file.

Im looking to add some information to a table in VB.net.The table needs 2 columns and a number of rows;1 Column needs to have numbers ranging from 1 onwards, basically representing their row number. And 1 more column which just displays any text when a button is pressed.
Each time the button is presed i need the text to go onto a new row.Ive heard alot about a DataGrid, but everything relating to this seems to be based with SQL and I was wondering if there is a differnet tool which would be simpler to use?

This does add a table in the table visual studios uses but wont save it to the main database. This means I can do a fill method and see the row while the program is running, but wont be there next time I run the program.
I'm trying to populate it with the results from a table in a dataset, something like Dim MyStringArray() as string = {Me.MyDataset.MyUsers.Rows.Tostring}. So I would end up with, StringArray() = {"Bob", "Jane", "Sally"}. I know I'm missing something very simple but I'm just not getting it.
View 5 RepliesI am trying to add a new record to a Visual FoxPro data table using an ADO dataset with no luck. The code runs fine with no exceptions but when I check the dbf after the fact there is no new record. The mDataPath variable shown in the code snippet is the path to the .dbc file for the entire database. A note about the For loop at the bottom; I am adding the body of incoming emails to this MEMO field so thought I needed to break the addition of this string into 256 character Chunks.

A new project requires that we have two servers set up to accept requests. Originally we had a reporting system which queried a database and brought back various details to the user. We now obviously need to query two database on seperate servers and merge this information to provide real-time reporting.

That is just an example, but my classes have around 30-40 properties and this brings a very large and complex sql string. Creating, editing or maintaining these sql strings for many classes could generate errors. I am wondering if any compact way or method exists in order to add the whole object's istance (the properties of course) to the table "TestTable" without writing such a large sql string. I created the TestRow in the way that its properties are exactly the columns of the table "TestTable" (with the same name). But I did not found in the ADO.NET anything that could be used.
I have a self referenced table it contains Employee information, an employee reports to another employee, I've done this by including a field named ReportsTo as a foreign key that would be filled with the primary key. My first question is when using a strongly typed dataset how would I insert the first record without raising an error. the only solution that I could come up with is to insert an employee with the name NoOne and reports to himself i.e the employee number is the same as ReportsTo, this solution would be hardcoded in my program and only works when there is no records in the table. This is ok as long as I don't delete every employee from the table and try to insert new employees, in this case my insert will fail because the NoOne employee number is "1" and this would violate the index. this case calls for reseting the index each time I delete all the employees.
