I use VB in VS2010..My form has a textbox..I can control the keyboard entry by using the SuppressKeyPress method..However this does not work for the Menu key - I think it's the menu key - the one that looks like a combo with an arrow.This produces a large drop-down menu which I don't want.On checking various forums it appears that the following code should work..[code]

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.

I know I have done this before and as I remember it should be really easy. But for some strange reason I can't do it now and I am about to jump off the building.I will make it simple:Two tables, one is just a list of products and their code.The other table: "details" has a field named product. I want to store only the code there.In the second table's entry form, I am putting a combobox. This combo box should display the list of products, their names, but depending on which one is selected, the code is what is passed to the table "details". Currently If I set the display member to product and the value member to code it still pases the product to the binded data source.

I have a database that holds information about a particular job. One of those things is a customerID. CustomerID links to another table containing customer details. I have a combo box attached to a custom object that holds customerID as the valuemember and CustomerName as the displaymember.The JobDetails holds the customerID info. How do I set the default selection in the combobox based on the ValueMember of the combo box?

in VB.NET you implement an interface like this...
Sub SomeInterfaceMember()
Implements ISomeInterface.SomeInterfaceMember
End Sub
while in C# you do it explicitly like this (which can only be called via the interface)...
void ISomeInterface.SomeInterfaceMember(){}
or more simply, implicitly like this...void SomeInterfaceMember(){} // Note the name matches the interface member However, regarding VB, I can also do this...
Sub SomeRandomMemberName()
Implements ISomeInterface.SomeInterfaceMember
End Sub
In other words, the method that handles the implementation can have a completely different name than the interface's member name.I'm just wondering if there's something similar to this in C#. (Yes, I know I can simply do an explicit interface, then access it via another 'wrapper' member with a different name that simply delegates to it, but in VB.NET?

I have been battling with this problem for months with virtually no success. I am using Visual Studio 2008 Professional. The database is Microsoft SQL 2005.
I have two combo boxes - both bound to database tables. These are: Combo box 1 is for "VAT" and is bound to the VAT table. This table has 3 columns configured as shown below:
[Code]....
The commented out code was my pathetic attempt to put the Value member of one combo box into the display of the other. This obviously does not work and my web browser, when using Google, is full of purple headers showing the sites that I have visited looking for an answer.
When I have this working, I want to use the feature in a datagridview which may make a difference to how the problem is approached.

I am using Visual Studio Express 2008 and I am working with datasets. I have made a form. Then brought in my customer detail from my Customer Data Set. Also from that same dataset I brought my orders into my form. then I went to the code view and had to edit some lines. the following is the code that I have. I am going through Beth Massi Form over Data Series videos.
Public Class Form2
Private Sub CustomerBindingNavigatorSaveItem_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles CustomerBindingNavigatorSaveItem.Click
Me.Validate()
[code]....
I am getting the following error:
'CustomerAdapterManager' is not a member of 'Form2'
and ' OrdersAdapterManager ' is not a member of 'Form2'
I have been watching the videos from Beth Massi, Forms over Data video series. I am on lesson 3.I just can not see where this problem is occurring.

Let's say I bound a combobox to a datatable. How can I get the valuemember of the currently selected item in the combobox (for example, when I have to save the data, I need to get the valuemember - PatronTypePK - of the currently selected item in cmbPatronType)? And can anyone check if I made the code correctly or if there are any programming practice errors/inconsistencies? I wanted to fetch two tables into a single dataset (Patron, PatronType). Do I have to make a datatable for each, or can I simply use the dataadapter?[code]...

I've had a program using Office Web Components operational for about 5 years. I just installed Windows updates to the Vista 64 operating system, and now under Visual Studio express edition with Visual Basic, I am getting over a hundred error messages related to the following:
'Office' is not a member of 'Microsoft'
So, for example, the program has references like
Microsoft.Office.Interop.Owc11.ChCharts
and I now get an error message
[Code]....
how to fix it so these error messages disappear? (Where did Office go, and does it still contain Interop.Owc11, wherever it is?)

I've encountered a problem which challenges my understanding of access modifiers in VB.Net. I have a class declared Friend. If I declare its properties Public, the application works. If I declare them Friend, the application fails.
Before this, I believed that, in a class declared Friend, it would make no functional difference whether I declared the members Public or Friend. I thought class access declarations applied their restrictions to all nested entities, so nested properties declared Public were effectively restricted as if they had been declared Friend. Obviously, I was wrong. Can anyone explain how access modifiers really work, or point me to the relevant documentation?
Here is a more detailed description of the situation: I have a Friend class called StripTask with properties called StripDate, HistorianDate, and TaskText. I have a collection of StripTasks (called _StripTasks) which is used as the data source for a Syncfusion GridDataBoundGrid. The way the binding works, I need to pass the name of a StripTask property to each of the grid columns so each column knows what data to display. It ends up looking something like this:_DataBoundGrid.GridBoundColumns(1).MappingName = "StripDate". When the mapped properties are declared Public, it works. When the mapped properties are declared Friend, the grid is populated with the correct number of rows, but every cell is empty.
As a follow-up question, is it a good idea to avoid things, such as this Syncfusion binding method, which require me to pass property names as strings? It just feels as if I'm inviting trouble.
