DropdownList At Properties Level Of ComboBox - Search Field Types
Oct 28, 2009I have a combo box on my application (working with VB.net) called CmbAttendantstatus. I have sent the dropdownstyle = dropdownlist at the Properties level of the combobox.
There are 200 field types e.g;
Current Attendant
Ever Attendant
Never Attendant etc
The issue is I can only select one from the list, fine, but I want to be able to type the first letter on the combobox and it takes me to the nearest field type rather than looking through the entire drop list. For example I want Never Attendant, I just need to type N and the drop list takes me to anything starting from N and if I add E for example any field starting with NE shows up for selection. Presently, when the dropdownlist is selected you are not allowed to type anything...
Detecting Different User Access Types In Vista?
Dec 18, 2010Within the application, I need to have two levels of access: Standard User and Power User,for example.These two levels can have the same access level within Windows.It is not my intention to elevate to administratoWhat is needed, is a way to have two different groups of users.ne group will be able to run the application while a second group has access to additional features within the application but not within the windows environment
It is my hope that there will be two user account types: 1) Standard User and 2) some other user type such as Power User or something else that will distinguish it from Standard User

View 2 RepliesC# :: Determining Object Equivalence For Value Types, Reference Types And ILists?
Nov 1, 2009I have a class with a Property called 'Value' which is of type Object.Value can be of any type, a structure, a class, an array, IList etc.My problem is with the setter and determining whether the value has changed or not.This is simple enough for value types, but reference types and lists present a problem.For a class, would you assume that the Equals method has been implemented correctly, or just assume that the value has changed every time the setter is called?If I did assume it's changed, then perhaps I should assume it for value types as well, so that the behaviour is consistent.
View 2 RepliesConvert 1 Field Into Many In Access?
Mar 30, 2011I download a file into access. One field contains one to many numbers always separated by a colon and a space: I have no control over the download. TheNumbers have a 1 to many relationship to a customer. Each number must then be verified against two separate reference files, and if the numbers match the description related to the number will be displayed.I'm just learning visual basic. I've made the changes manually (yuk-this took forever); I've tried various string/conversion commands; I've taken the data and placed it into excel and tried to manipulate it, without success.In this case is always numeric. In another field, similar problem, it's a combination of text and numbers.
Example: Cust# TheNumbers
99 1234; 12345678; 123123; etc...
88 87654321, 345654, 98989898. etc..
The numbers can vary in length and quantity. For each customer each number must be loaded into one field.
Example outcome:
Cust# TheNumber
99 1234
99 12345678
