I just released two more videos (#15, #16) in the Forms Over Data video series. One is on understanding data binding and how it works from database all the way to the controls you see on forms. We talk about the relationship between the TableAdapter, the BindingSource and the DataSet and I show how to work with data in your code.
The second one explains how to update related data tables like I explained in this post. This video doesn't go into how to set up the transactions but you can read about how to do that here. I've also attached the code from the videos here.
Take a look at this blog post: http://blogs.msdn.com/bethmassi/archive/2007/10/01/using-data-across-multiple-windows-forms.aspx

hi my name is saleem can you answer my question please
i made a simple media player with vb.net 2005
it is working well but i had these problems
1-how can i get all of file names i selected and pressed enter to play them with my application
i tried startupnext instance event and i got all file names but this was a very slow way and doesn't work well when you have alot of files
i mean i have to wait every file name to be sent to an instance of my application
please can you tell me what the way is to do that(
maybe the way that is used in windows media player)
2- how can i next the song by pressing nextmedia button while my application is minimized and i am working on another program like a word ...
3- i can drag and drop files from windows explorer
to my playlist
but i cant drag files from openfiledialoge to my play list
I am developing databound application where I am putting all the datavalidation on dataset (in table.columnchanged event by setting row.setcolumnerror and also in tablenewrow event). Before saving the record i use dataset.haserror to check if it contains any errors. It work fine with when i edit and save the existing records, but while adding new records dataset.haserror always return false eventhough many row.setcolumnerror has been set.
I hope u understand my problem.
Eagerly awaiting your solution.
Thanks in advance.
Hi Beth and thank you so much for your "How do I" video series and this blog. It is very educational for people. I have a question for you. In your video "How to create a Search Form" you are showing how to implement search by using gatagrid (not a detail view) on the form. Can you guide me or lead me into the right direction if I am using detail view such as text boxes. Thank you in advance.

plzz tell me..
where i can learn... ??
pllzzz.. beth messi
it was so much useful watching ur video. i could sucessfully update the two related tables in my form but now i need to deal with 4 related tables is the same form (customer : parent) , (order : child) and the (order) table is the parent of (order_details) and (payment) child tables. please help me with this , thanks in advance
The technique is the same with two related children. Here's a video that shows how to set up the relationship between a parent and a single child.
Just follow the same settings on the second relation as the first. Then the TableAdapterManager will perform the updates in the proper order.
thanks beth you are the best!
but i need help. i'm having trouble on a search form. how do you make a search with dates. like i want to select only registrys on this month. or year. or an specific date.?
Thank for your video series. And i have a question for you
When i working with DataGridView, can i use two or more datasource for One DataGridView.
I mean, for instance,
As you show in LookUp List video
You Create Product Lookup in OrderDetail's DataGridView, u just create ProductNo(that have relation with orderdetail) but i want to add some field from product table at the same grid(example some description about the product we select).
Need To show (ProductNo) and (ProductName) something like this.
For Entry we select ProductID(from ProductID Lookup Combobox) in the DataGridView
and other colum show the Name of the Product we Selected(by Retrieve form Product Table)
All in All
can i show ProductID and Product Name at OrderDetail Datagridview
