I am using MS Access 2007. There are 2 tables in my database. One is for payments and other is for departments. In payments table, there is a field for departments. In my VB 2010 project, i want the departments field in the payments form to be in list box. And during the program is running, i want the option to add new departments and as soon as new department is saved, the list in payments form should also upadte.
What is my question? Well I believe its not a really hard one for those who know Basic.
Im trying to create a LogBook for an online server. What is the purpose of it, its simple. Right now we are doing it in a forum each one posting in a Log Thread, which game server they did the activity on, date, and time spent.
I have created the program so far, and what i would like to know, is if it would be possible that in the Texboxes i have, once you click submit, you will send the info to a Databse table.
I have a datagridview which is bound to a local databse table through a Linq to SQL class.
Everything works as I would expect, when the application runs, up to a point.
If, in the datagridview tasks pane I enable Adding, Editing and Deleting all work as expected.
If I disable Adding & Deleting, leaving Editing enabled, Editing works as expected.
If I disable Deleting & Editing, but leave Adding enabled, Adding does not work, despite the row for new records being displayed. I can move around the row but not enter data.
I suspect somehow its the datasource as opposed to the datagridview that is the cause of my problem but as I say, I can add rows if the Enable Editing option is selected.
Changing the relevant properties programatically makes no difference.
I've been searching for the reason for a couple of days without success.
I have a workaround, by leaving Enable Editing set and programatically setting each row during the RowPostPaint event to be readonly except the row for new records. I would just like to understand what is going on.

I am using a string builder to set up an html table row by row so that it can be emailed. I currently gather my information from the database using a data reader and while dataReader.read, I use stringbuilder.Append to add each cell value to the table.The issue is that after about 200 rows, the html breaks and displays a cell value above the table in the email. I have tried changing the cell padding, but this was not successful.
[code]If I wanted to get Part Name for multiple PartIDs from OrderDetails, how would I go about doing this? Would I use two DataTables? I'm confused as I cannot see an efficient way to do this. The only thing that I can think of is to create a DataTable with SQL:[code]and then maybe use a For loop to take each PartID, create another DataTable to find the PartName for that and then give this to a variable. There could be up to 10 PartIDs to search through and I don't want to have variables such as PartID1 PartID2 etc. [code]
[Code] my issue is that now i need two cases, first i need a query that will return the date created and modified of the table and i also need to know if its possible to query a list of table names in the database ordered by date created but that have a certain thing in their names. for example the database contains the following tables: [Code] and what i need the query to return is the tables that contain "Data", settings and employees are for the other functions of the program. so the query should return the 4 data tables in order of date created. but i have no idea how to go about doing that in the query, does anyone know how this is done?

I have been doing some listings from database, from the table "Clients", however, when it arrives to the field "Status", like it was expected, it displays to me numbers (1, 2, 3 or 4) these numbers have a relationship with another table, called "Status", which have: Single, Married, Divorced and Widower (according with those numbers).
So, I'm using a DataSet to list all the field, how can I retrieve the text in the table "Status" according with the IDClient instead of retrieving numbers?
