VS 02/03 Use A Double Dot Notation Instead Of The Single Dot Notation?
Apr 11, 2009I am trying to have a firm grasp of VB.NET and wondering if there is a way to use a double dot notation instead of the single dot notation people are normally accustomed to?The double dot notation that I want to implement is shown directly below:
PersonData.Birthdate.IsValid
Currently, the only way I know is by using the call shown below which I suspect is not using the full capabilities of .NET:
Validations.IsValid(PersonData.Birthdate)
My code is shown below:
vb.net
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
modVar.intDay = 25

Private Fields Have To Be Declared Static?
Aug 18, 2010I am a vb.net programmer switching to C#.I have the following code for a console application (targeting NET20)
using System;
using System.IO;
using System.Data;[code]....
This is giving a compile error in the if clause of InitVars for the _dbName variable:
Error 1 An object reference is required for the non-static field, method, or property 'eScoreSwapper.Program._dbName' C:UsersSethSDocumentseScoreVersionsTrunkdotNeteScoreSwappereScoreSwapperProgram.cs 26 38 eScoreSwapper
C# does not allow you to reference private class fields unless they are declared static?

Nov 12, 2010I am trying to implement transactions across multiple TableAdapters in VB.NET (using Visual Studio 2010) by extending the partial class as described in the following examples:

Private Fields Flagged As WithEvents Are Taken By Code First To Build An Automatic Foreign?
Jan 22, 2012a simple question. Given the following code:
Public Class MyClass
Private WithEvents pPerClass As PersistableClass
Public Overridable Property PerClass() As PersistableClass
Get
Return pPerClass
[Code]...
the first being a duplication of the second key, strangely obtained from a private field.
If you remove the WithEvents keyword, the pPerClass_PersistableClassID key is not created.
I am new to EF but it seems to me a strange behaviour.

Unable To Absorb Official MS Docs

View 2 RepliesAsp.net - Prevent Numbers From Showing In Exponent Notation?
Oct 21, 2009I've got an app that sometimes stores some decently small numbers, such as 0.000023425. These numbers get loaded up in TextBox controls for users to edit.
Dim number As Double = 0.000023425
someTextBox.Text = number.ToString() ' Shows "2.3425E-05"
As mentioned, the text that shows is 2.3425E-05, which isn't exactly intuitive for the user to see, plus I have numbers even more precise (out to 19 decimal places). I would like the output to be fixed point. Of course I could easily and cleanly do:
number.ToString("F20") ' Shows "0.00002342500000000000"
But then there's an annoying number of zeros left over. So, to fix that, I could do:
number.ToString("#,##0.####################") ' Shows "0.000023425"
Which is what I want, but is there any better way to do it than to have that giant ugly format string there? So, ok, it's not that ugly, but surely there's a different way, right? My goal is to show the raw value being stored in the DB in a friendly way, and I would rather not have to force a format on the number at all.I found that changing the underlying datatype to Decimal solves the issue.
Dim number As Decimal = 0.000023425
someTextBox.Text = number.ToString() ' Shows "0.000023425" instead of "2.3425E-05"
So it sounds like Doubles aren't precise enough to be displayed normally?
Converting Double To String (Not In Scientific Notation)
Nov 12, 2011The only post I can find on this matter is one that coverts the double to a decimal before converting it into a string. However the numbers I'm using are far larger than what a decimal can store.
Example: 1/(16^10)
So how can I convert the solution to the problem above. Which equals 0.00000000000090949470177292824, to a string value that is exactly as it's shown?
Cause when I convert this to a decimal I still end up with a string in scientific notation..

Dynamic Draggable Labels On Chart For Notation Purpose
Jul 22, 2010 I am deveolping a charting program and have a need to have dynamic draggable labels on the chart for notation purposes. Everything works fine until I try to drag a label past the 32767 (16 bit limit).
Here is the code that I drag the label with:
If ISDRAGGING = True Then 'DRAGGING LABEL
If CURRENTLABEL.Tag = 2 Then
CURRENTLABEL.Left = 0
[Code] .....
I have tried to create a new label and override the Top value with a Long Value, but it still does not do the trick. Hhere is my attempt to overload the top value to an integer.
Public Overloads Property Top() As Long
Get
Return _Top
End Get
Set(ByVal value As Long)
[Code] .....
The charts are dynamically generated from a database and represent depths. Usually at least 10000 feet are plotted at 5 pixels per foot. So some labels will be created or dragged below this 32767 line regularly. Any way to be able to drag the labels past this limit, or possible another option to be able to view these long charts.
EXCEL Reads A Text String As Scientific Notation
Dec 31, 2007I am working on a project that involes reading an Excel file, picking through it, then creating a flat CSV file. One of the the data elements I am picking up is a 9 character string that may be numeric, or contain one or more alpha chatacters. Excel has a nasty habit of converting long numerics to scientific notaion. I can overcome this by converting the "general" string to "TEXT".
However, there is one instance where I can not get the function to work...the string is "90333E108" ( the CUSIP for USU). Regardless, the text string is saved properly into the CSV file. When opened in a text editor, it reads correctly.
When opened with Excel, it is in scientific notation. Changing the field to "text" from "scientific" still displays "9.03E+112".
how to create an csv file that Excel will open and read correctly?
You can test this by creating an Excel workbook, format all cells as TEXT and add the following data:
90333E108

C# - What Is The "official" Place For Community Support For The Mere Mortals .NET Framework
Jun 14, 2010My team is using the Mere Mortals .NET framework from Oak Leaf. Being used to working with primarily open source software, I found it excruciatingly painful to find ANY community support for MM.NET. When I asked if there was any, the only place I was given to look for support was Universal Thread, which is a site which requires a membership for search on archived questions. It seems like a third party, pay-for site should not be the primary source of support for anything like this, especially MM.NET which costs $700 per developer. It doesn't seem to me like an entire community around MM.NET would choose to all pay on top of the license just to use a forum. If not Universal Thread, then what is the "official" place to find support for the Mere Mortals .NET framework?

Refactoring A Module Into A Class: Changing Shared Fields To Instance Fields
Nov 14, 2011I'm currently refactoring an old Visual Basic DLL (VB.Net), which stores all of its data in one module called Globaldefinitions as public fields. There are about 200 fields, referenced thousands of times all around the code:
Public Module Globaldefinitons
Public a As Short
...
Public zz10 As Double
[Code]...
I need to change the module into a class with non-shared fields. This means, each and every of these thousands of references needs to reference the instance of that class:
globalDefinitionsInstance.a = 5
How do I go about this efficiently?
Regular expressions operating on the source fall flat. Refactoring tools like Re-Sharper or CodeRush don't seem to offer this functionality. Visual Studio 2010 cannot do it automatically either.
Can The Initialization Order Of Class Fields In .NET Be Influenced By References To Other Fields
Jun 19, 2011Class Foo
ReadOnly name As String
Public Sub New(name As String, dependentUpon As Foo)
Me.name = name
[code]....
The output of New Bar() is:
Dependent created. Dependent upon nothing.
Independent created. Dependent upon nothing.
It seems fields are initialized in the same order as they appear in the source code, which (a) leads to an unexpected result, and (b) seems a little puzzling, given that one is normally not permitted to read from uninitialized variables in .NET, yet that seems to be working fine above.I would've expected VB.NET to be smart enough to initialize referenced fields first, and only then those that reference it; i.e. I'd have liked to see this output instead:
Independent created. Dependent upon nothing.
Dependent created. Dependent upon Independent.
how to get VB.NET to behave like that instead, without simply having to swap the declaration order of dependent and independent inside class Bar?
Create Word Form Fields With Memo Fields From Access?

However the fourth field is a memo with >255 characters.I'm struggling to come up with the proper code to allow me to populate the Word field with the memo data that has more than 255 characters.
