Got an issue with lstFriends.Items.Add part of this code, says that "Items isn't a member of String". What does that mean exactly and more importantly how do I fix it so this code will work. What I am trying to do is make it so the btnAdd will add a name to lstFriends if it's not there already and for the btnRemove will remove a selected name

View 1 RepliesFor my ToDo list I need lots of variables to store data in.Each item of the list has 3 strings in it: Activity, start time and end time.To make multiple tasks in my ToDo list I think it's the most usefull if I use this: 'For x = 0 To 1000', so on the launch it will make 1000 variables to store my data in.But for the 3 string for extra info I need something like this:
x.a
x.b
x.c
Where x is the integer, and a, b and c are the 3 strings. If I try to do this I will need to do 'Dim a, b, c as String', but that way it will not understand x.a x.b and x.c If I do 'Dim x.a, x.b, x.c as String' it gives me an error, because x.a is not a String...
How can I get the type (it's name as a string) of:
1) an unassigned member?
2) the current class (I mean the one in scope) when no instance is available and without using a shared method?
EDIT: Come to think of I, I'm starting to think 1) is impossible.
EDIT: 2) may in fact never occur as such. Actually I meant the parent class of a nested class when no instance of the parent class is available (but an unassigned variable is) and without using a shared method of the parent class

Public member 'Selected' on type 'String' not found. I'm assuming this error means you can't select a String in the combobox?

I'm "cloning" objects in my code. For instance: objClone = objOriginal My question is: Does the assignment operator in VB.NET 1.1 do a member-by-member copy of the objOriginal to objClone or does objClone simply point as a reference to memory referenced by objOriginal?

I have 2 tables Table A & Table B Table A has the table values that I want to be populated in a datagridview control.The challenge is that column 1 in table A contains an ID(foreign key) to a name field that is a located in table B. I need the datagrid to have the first column be a combobox that displays the names(from Table B) that are already in table A via the ID's, but reference the populating values from Table B. So that when you bring down the combobox you would be choosing from Table B data but populating table A with the ID and you would see a name there instead of an ID.[code] How do I populate my DS dataset with Table B? And how can I create a link to these two tables using a bound datagridview control?

I get this error if I follow these steps: Change property Y of an object (an associated entity property)
Attempt to submit changes At this point the value of Y and the value of X (the underlying key) are not in agreement -- LINQ to SQL apparently doesn't synchronize these until GetChangeSet is called.An expected error occurs due to some business logic or database level constraint during the update operation.At this point the value of Y is in agreement with X because GetChangeSet was called.Change the value of Y to Nothing (aka null).Call GetChangeSet.
The error occurs on the last step because the value of X and the original value of X (returned by GetOriginalEntityState) are different, and the new value does not agree with Y? Is that why? Is this a bug in LINQ to SQL. Must be because I don't see the same behavior if I change Y to another (non-null) value instead during step 5. What's the right way around this? I can see a few ways:
Discard the DataContext when an error occurs and leave the UI as-is. I don't like this because then optimistic cocurrency change conflicts cannot be detected. The new context doesn't have the original values in it that were populated at the same time the UI was populated, so if the UI has any stale values in it, they will cause data in the database to revert.Refresh the datacontext (OverwriteCurrent) and leave the UI as-is. I don't like this for the same reason as #1.Refresh the datacontext (OverwriteCurrent) and re-populate the UI. I don't like this because then the error message just presented to the user does not show the user the error they made and allow them to correct it. It also discards all the other changes the user may have made.When the error occurs, explicitly retrieve the key for Y that corresponds to the original value of X and reset Y, then call GetChangeSet to re-synchronize X (X is read-only or private so I can't reset it directly). This seems to work, but seems like a hack, and may require lots of code for other similar errors.
