View 4 RepliesI need to populate single record at a time based on the search criteria. For example I have employee_name and the other personal information of an employee. I need to display a single record at a time based on the name entered by the user(The important point here is that I need to populate the name combo box here for the employee to select the name). I do not want the results to be displayed as a datagridview. I think I can do this if it is a datagrid view but I want display each field one below the other separately as a single record.

The "FullName" works with textbox1 when i select a value in the combobox but I want to display the "Name" in label1.text
I am just making the switch from WebForms to MVC and would like to ask what are the best ways of hiding particular fields in the view. Assuming we have a model named WishList that has a list of gifts kids want for Christmas and the child's name. We want the elves to view the list of gifts, but only Santa Claus can view the child's name. Would it be best to have two views for the WishList (one for Santa and one for the elves) or is there another way to handle this? My concern is that the number of views can start piling as high as the snow does in the North Pole by the time I enforce all of the visibility settings required in my application.

Ok, so here is the problem. I need to pad the ID field to a length of 10 to make the display in the list box look right. I also only need to display the ID, last name, first name, and middle initial. I have no idea how to implement this in to the code. I included the studentList.txt if anyone feels inclined to run the program.

View 3 RepliesI have a field in a SQL Server 2005 DB of type 'image' that contains documents, mostly pdfs. When I view the field in the database, it looks as though the data is stored as a hex string. I have extensively googled and came up with the VB.net function below to convert the field to an actual file, but it only outputs a file containing the string of hex characters rather than the file that the field is supposed to represent.
This is a sample of the fields' data (I have truncated it for privacy purposes):
