View 2 RepliesI am working in vb2008. How to store Class/Structure instance data into a database as single objects.
SomeClass
.name
.address
.age
.etc
Say I have a hundred instances of "SomeClass" stored with data. Is there a way that I can store each of my hundred instances as a hundred objects to a hundred Access database records. I am trying to avoid having to mirror my class structure into a datatable and treat each instance as a single object which can be stored into a single database column name.
Can anyone tell me why "Rows cannot be programmatically added to the DataGridView's rows collection when the control is data-bound." I keep getting an error "Invalid Operation Exception was Unhandled" error. All I am attempting to do is allow the user to select products from a list(or a second datagridview) and have it added to the datagridview so they do not have to type in every cell since the other cells are not visible because they do not purtain to their needs. Plus they will be able to save all items at the same time.

View 3 RepliesHow do I put a large amount of data (we are talking of a datatable with probably 50 columns and maybe 500 rows) from the access database that is bound to a datagridview in my program into textboxes depending on the row of the datagridview row I am clicking on.
What I have in the access database is countries and companies that are attached to several different dates to each company. these dates are supposed to be filled into the textboxes automatically when I click on the company row in the datagridview and also when i fill in a date in the textboxes it is to be written to the access database when I save the update.

View 3 RepliesHow would i delete only the successful inserted rows for insert and then move the non successful rows up and allow the user to correct the data and get it ready for an insert. If i dont delete the successful rows then i will have multiple inserts of the same dataRow and we dont want that!

View 1 RepliesIt was even difficult coming up with a Question title for this.
Am not sure whether am using the right approach to my problem. See i have this datagridview that contains rows that i would like have saved back into the Database as new rows but with a column altered to a new value.
Eg
PKColumn1 FKColumn2
Column3 Column4
1 1

What am looking at is Change FKColumn2 (some foreign key, maybe i can also have a combo box somewhere on the form and an "import to") values to something like 2 and save the rows back to the database without loosing the original rows.
I have several problems with rows in a DataGridView. Background information: The DataGridView (DataGridViewCalib) is in one TabPage of a TabControl, some columns of the DataGridView are automatically DataGridViewCheckBoxColumn as the DataSource have some colums which are Boolean. This is a Windows Form written in VB.Net with Visual Studio 2008. The user loads an input data file.
The problems:
1) At first arrival in the TabPage, ShowDataGridViewCalib (code below) is called. All rows are then shown in the DataGridView, despite the code saying that some rows should not be visible. Breakpoints in the code show that the code do arrive at the Rows.Visible = False events. Despite all rows beeing shown a Watch in the debugger shows that:

There are two alternative ways of handling the rows in the code. The first attempt (commented away here) is probably the "nicest".

For example if I need to send a instruction like "START:0.01" to the external device which are the libraries that I have to include?, how should I write the programming line to do this?
The main tasks that I need to program are sending data, receiving data, and saving data
