Is there any nice way to specify that a numeric literal is a byte, other than via silly CByte()? Other numeric types allow one to append a suffix (e.g. s, l, ui, etc.) but I can't find any such suffix for 'byte'.
I guess the unfortunate handling of the 'Not' operator means that a constant byte which equals 1 is not the same thing as a constant integer which equals 1, so the compiler can't simply regard constants as being the smallest type in which they'll fit, but it's still irksome to have to use:
byteVar = byteVar Or CByte(1)
rather than the cleaner:
byteVar = byteVar Or 1
(FWIW, my preferred handling for the 'Not' operator would be for the compiler to regard its output as a signed item large enough to fit the operand, except in the case of 'variable = Not (expression)', in which case its type would be the same as the operand. The result of the 'And' operator would be the type of the smaller operand, so "byteVar = byteVar and not 5" would work without complaint. Such handling would avoid the tricky bug in:
longVar = longVar And Not somethingSmaller
since the sign-extension of the 'Not' result would ensure correct behavior in the upper bits.

What you're talking about is called a Forced Literal Type. The characters denoting these are:
Literal type char Data Type Example
S Short I=347S
I Integer J=347I
L Long K=347L
D Decimal X=347D
F Single ... you get the idea ...
R Double
US UShort (Unsigned Short)
UI UInteger
UL ULong
C Char
There are no Forced Type Characters for Boolean, Byte, Date, Object, SByte, or String data types, or any composite types.
So, no, there's no easy way to do this, other than defining a constant as a byte:
Public Const MyTrue As Byte = 1
byteVar = byteVar Or MyTrue

Oh well, thanks. I wonder why there isn't a Forced Type Character for byte? It's not as though "b" is used for anything else.
Is there any way to set "Option Strict" to be a little less strict in VB2005? Some of the squawks are helpful, but some are pretty annoying (particularly given the lack of a byte FTC).

No, there's no way to change what is and is not covered under Option Strict. You can, however in a limited way, tell the compiler what to throw an error on, or warning, or no message at all. Just go into the projects properties (My Project), Compile tab, and change the Notification options you want. Implicit conversions are covered by the first three options in the list.

Hello,
I'd like to know if it's possible to register a filetype/extension, eg "*.xyz" as "New Program File" at installation or program startup. It doesn't have to be linked to a program.
Thanks in advance, 
--Zaegra--

Yes it is possible.
Here[^] is a link to Microsoft's documentation about File Types. And there are pletny of articles on Code Project[^] to get you started.
Hope this helps.

I've just starting in VB.NET and would like to know if someone could help me out with a minor issue I have.
When I use INPUTBOX(), the textbox is shown on the screen but the text message isn't.
Anyone would know why ?
Again, must be something very easy.. just new to this .NET world

This question would be better asked in the Mobile Development forum.
Without seeing your code that displays this box, it's impossible to say what the problem is.

Hello:
I am sending a text stream across a TCPIP nextwork and it works fine. Accept .... when I send the word "[Capture]" across the network. I changed the case of the C at the begining and it works fine. Also change to "{" brackets and works fine. I could just change the brackets or the C to a lower case c but I just am trying to figure out why it fails. The error message is IndexOutOfRangeException.
Thank you in advance

There's nothing special about the word "[Capture]" that would cause this. It's probably because of a buffer problem, but with out seeing your failing code and the line that the error occurs on, it's impossible to say.

Hi i was wondering if anybody could help me figure out how to translate a sentence from english wording to british, i have already figured out how to translate single words but i am having a hard time finding how to translate sentences. If anybody has any ideas, it would be greatly appreciated.
Below i have included my current soure code and the text from my text file.
Source:
Public Class Form1
Structure reader
Dim eng As String
Dim brit As String
End Structure
Dim words(11) As reader
Private Sub wurd_load() Handles MyBase.Load
Dim sr As IO.StreamReader = IO.File.OpenText("words.txt")
For i As Integer = 0 To 11
words(i).eng = sr.ReadLine
words(i).brit = sr.ReadLine
Next
sr.Close()
End Sub
Private Sub btn1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btn1.Click
Dim searchword As String, result As Integer
searchword = txt1.Text.ToLower
result = findword(searchword)
If result >= 0 Then
ShowData(result)
Else
MsgBox(searchword & " not in file", 0, "Not Found")
End If
End Sub
Function findword(ByVal searchword As String) As Integer
Dim first, middle, last As Integer
first = 0
last = 11
Do While (first <= last)
middle = CInt(Int((first + last) / 2))
Select Case words(middle).eng.ToLower
Case searchword
Return middle
Case Is > searchword
last = middle - 1
Case Is < searchword
first = middle + 1
End Select
Loop
Return -1
End Function
Sub ShowData(ByVal result As Integer)
'Display the data for the specified state
txt2.Text = words(result).brit
End Sub
End Class

Is this a joke ? English to British ? What do you mean ?
Translating sentences is very complex, because rules of grammar change, that is, when you actually have two different languages to translate between.

Basically i want to know to to "Translate" multiple words instead of one from the textbox, like two words or three instead of one.

Oh - you can use the string.Split method to break a sentence into words, then translate each one.

Why do you keep posting the same question over and over?? The answer has not changed since you asked this very same question on April 1st and May 2nd, and will not change today. The .NET Framework SMTP Client classes do not currently support using a proxy. You will have to find a 3rd party library that does offer proxy support. I currently do not know of any, but I'm sure they exist. All it would take would be 5 seconds worth of Googling to find some.

I am writing a program that runs active sync and syncs a file on a device when it is put into the dock. I want to write a program or windows service that runs when active sync syncs up with the device. Is this possible?
|
|
|
|
|
It's possible only with windows service or working background programm which detect this device and then run main program.

Hello, i have a little problem with zedgraph (used in vb.net):
On a form lies one zedgraph which shows one chart (curve).
I want to resize the form, but not the chart/curve. In the form's resize event i set the size of the control.
With ZedGraphControl1
.Top = PanelPatientInfo.Top + PanelPatientInfo.Height
.Left = 0
.Height = Me.ClientSize.Height - .Top
.Width = Me.ClientSize.Width - .Left
End With
But when i do this the complete chart is scaled. (It is like zooming in/out...)
I want the maximum of the x and y axis to get greater/smaller.
How can i do that?
Thanks in advance!

Uhhh, maybe I just don't get the requirement, but if you don't want the chart to resize, why did you supply all this code to resize the chart??

Hmmm, ok...
Let me try to explain it.
When i resize the form (on which the zedgraph lies) then the zedgraph should fill the form. This is working fine.
What i want is: The bigger the form and the zedgraph control gets, the bigger the max value of the y/x axis should become.
Example:
My form is 200x200 pixel and the zedgraph too. The maximum value on the y axis is 200.
Now i resize the form manually to 300x300. So i want the max value on my y axis to increase from 200 to 300 too.
At the moment only the chart (which is contained in the control) gets resized.
How can i change the max value of my axis?
Many thanks in advance!

That's a question for a forum that specifically deals with ZedGraph. I have no idea how to use that library since I've never seen it. But, it sounds like all you have to do is take the width of the form and plug that into the Y-Axis of your graph. How you do that is a question for the people who wrote ZedGraph.

We have an application that we have installed on 3 PC's. I seems to work fine for the most part. We are having
a problem with one PC. There are 2 different people that login on this PC and use the application. If we install it under one login and the other login gets on they always get this message. "The feature you are trying to use is on a network resource that is unavailable ?" It is trying to go back to the network location
from where the setup.exe and .msi file are. Any ideas why ? Thanks in advance for any help.
Thanks
Tom
