View 3 RepliesUsing VB 2008 Express, I've constructed a simple database type app for saving contacts. The table data I save at design time is always saved correctly but data entered at run time seems to get saved even after closing the app and VB. However, after restarting the computer, the newly entered data is usually gone. Why would this be? I've seen a few video tutorials on creating simple database apps and did everything they did and am getting the same problem. I thought it was a configuration problem so I actually re-installed Windows and VB 2008 Express (as well as 2010 Beta 2). I have noticed that in the database explorer, the .mdf file has a red x to the bottom right of the yellow database icon and when I click the + it seems to turn into a black plug. Is this normal?

View 2 RepliesI have three tables in SQL server which I would like to show and access on a form. Table 1 contains account data, address, contact details etc. Table two contains data attached to a Person, tel no , Mobile no, Email etc. Table three contains details on what awards the person holds, i.e. one person can hold several awards.
Therefore I have a one many relationship between the first two tables and a one many relationship between the second two tables. This is set up in SQL
The first two tables are shown on a form, table 1 via a set of text boxes, table 2 via a datagrid control.
I would like the functionality whereby I could select a row in the datagrid showing the persons name and find the Persons_ID number then use that as a filter to a second datagrid view so that only the selected persons awards show in the datagrid.
What I am trying tot achieve is the following:User inputs data in one form that saves to the dataset table no problems. On an edit screen I want the current data saved to appear in this page within all the relevant fields but when saving I want this data to add to the dataset table as an additional line of data so the transaction records are kept.I want to add a new datarow regardless of it saving one change or all 7 changes that are possble.
e.g. Line 1 - user inputs 7 cells of data Line 2 - user amends 2 cells of data Line 3 - user amends 1 cell of data an so on. Unfortunately the terminology for certain items above may not be correct as I am still new to this programming and still on a massive learning curve.At the moment I do not have the code for what I am trying to achieve as I really dont know where to start with it.I am currently able to save the data and have it appear in the "edit" panel however only the cells changed are saved an it overwirtes the initial input.

I'm trying to access a database which is presently saved in .cds format (which I believe is a TClientDataSet) from within my programme written in VB.Net. The reason being, is that the programme I am writing uses the same database as another programme. Both programmes will never being running at the same time, and it is a read-only operation so I could potentially duplicate the database and convert the database to an SQL-compatible format, but obviously this isn't a tidy solution.Is there anyway that I can directly read data from the .cds file with VB.Net? It seems like this would be something that is not too complex and wouldn't be too different from just reading a .csv file.
