VS 2005 - Length Of Array Is Integer Variable

Apr 26, 2009

I have a problem when debugging a code. On top of class I declare an array, and the length of array is an integer variable which is applied value below declaration of array.

E.g. class declaration
Dim array1 (2, integer) as string
Public Sub
integer = 5
End Sub

So basically, array is created with integer being 0 or whatever, because it is declared before integer was assigned a value. But the problem is, I need it to be declared at class variable so I can use array in different subs.

Document Lines Length - Enable As Float Integer?

Apr 16, 2009

I was working on editing a code for a simple text program, but when running the program for multiple lines, the text being read gets too long or too many lines, the computer slows down alot and almost stops functioning. I am using standard integers like document.lines.length or listbox.lines.count. I think these are standard integers and I need to know how to enable them as Long of Float Integers.

I'm assuming I just change
Dim X as integer to
Dim X as long
or Dim X as int16

But I'm not sure as everytime I change something I get cannot convert to double. The code I'm interested in changing is ...
For i As Int16 = 0 To ListBox1.Items.Count - 2

The list box will only get to about 3000 items or so.
and
For iPos = 1 To xy
If Mid(sString, iPos, Len(Text1)) = Text1 Or Mid(sString, iPos, Len(Text2)) = Text2 Then
JJ = TextBox1.GetLineFromCharIndex(iPos)
This read box will read documents above 32,000 lines, which is the reason for not wanting to use Integer.

VS 2008 : Error: ConvertToMonth Is Not A Member Of Integer

May 20, 2009

I ran into a strange issue over the weekend while I was working on an asp.net mvc project in vb.net. I created an extension method to convert an integer to the corresponding month it is associated with. I tested the extension method in a console application so I know it is working. In my asp.net mvc project I have a view and want to call the extension method but I get an error that the extension method is not recognized. I imported the namespace it was contained in and still couldn't shake the error. Any idea what's going on? The code is below.

Extension Method:

Imports System.Runtime.CompilerServices

VS 2005 Configuring A Datasource Value Member & Display Member

Jan 6, 2011

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?

.net - The Member 'X' Was Changed To Be Inconsistent With The Association Member 'Y'?

Jan 3, 2011

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.

ComboBox / Binding / Display Member & Value Member

Aug 31, 2011

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.

In C#, Implement An Interface Member Using A Member With A Different Name?

Apr 4, 2011

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?

Error After Implicit Conversion Of 1 Dimensional Array Of Integer To IEnumerable Of Integer() ) ?

Apr 25, 2011

I'm trying to create a linked list of an array of integers. Why is the following implicit conversion required?

When I run the code that contains that conversion, I get the following error.

As a real-time data acquisition user control data (a packet of an array of bytes) arrives every second, is converted into an integer array and inserted into a linked list.

The most recently arrived data is painted as coordinates on a grid at the right of a PictureBox using Graphics.DrawLine (pen,X1,Y1,X2,Y2).

The oldest data (arriving 120 seconds ago) will be drawn at the leftmost portion of the Picturebox.

Why a linked list rather than a list? To display 120 views of time sequence data, the draw routine the most recently inserted node to a node that points to Nothing. How do I limit the length of the linked list to 120 nodes and always ensure that the last node points to Nothing?

Do While Not item Is Nothing
item = item.NextItem

'AddressOf' Expression Cannot Be Converted To 'integer' Because Integer Is Not A Delegate Type

I'm trying to convert a VB6 project to .NET, but I get problems with some callback functions, and the following message comes up: "AddressOf' expression cannot be converted to 'integer' because integer is not a delegate type" I've seen several solutions to similar problems like this, but I am not able to understand this issue with delegates.

After the conversion, the code look like this:

Declare Function vsmsgwSetDataPackageCB Lib "vsmsgwW.dll" (ByVal PACKAGE As Integer, ByRef arg As Integer) As Integer
Dim arginitP As Integer

Which gives the error: Method 'Public Function PackageCB(HisNodeID As Integer, ByRef data() As Byte, ByVal length As Integer, ByRef arg As Integer) As Integer' does not have the same signature as delegate 'Delegate Function DelegatePackageCallback(hwnd As Integer, lparam As Integer) As Integer
