if the format of your range remains the same, you can get the 'A' out and add one to its ASCII value and then change it back to 'B'. But I am not sure if it helps.

I am assuming this is XL.
You would do it like this...
Range("A1").Select
Offset(0,1).Select
Of course the (0,1) could be reassigned as variables and called within the Offset method.
That way you do the calculation then apply to the Offset and move around like that.
Hope that helps.

I would like to know how many bytes are sent/received by my application which is using TCP/IP.
There are Windows Counters which let you know the total amount of data sent/received by RAS or LAN adapters but I didn't find code to know what my process is sending (execpt for some professional and expensive tools which monitors everything and are third party software).
I cannot just count my bytes because TCP/IP overhead is also present and I want to include that too in my statistics.
Thank you.

I have several usercontrols that inherit from an other control.
I need to be able to set a property for all these (and other) controls.
But I don't really want to be writing a select case for all these controls, is there any way to know the type of the 'base' control?
|
|
|
|
|
I have some extended controls (tabcontrols, textboxes, etc).
I use checks like:
For Each oControl As Control In fraOffsets.Controls
With oControl
If TypeOf oControl Is TextBox Then
'Do work here....
End If
End With
Next
All textboxes on this frame are extended, but pass because they are all of type textbox. If your talking about a composite control, I don't know - other than you might set a property to designate it (like Tag or create one).
Did either of these suggestions work for you TDDragon?

I'm looking for any advice on what is a good barcode scanning device that is easy to use with VB2005. I'm thinking of developing an application that would read a Fed Ex barcode and update one of our internal systems with the tracking number. Thank you.

AFAIK most barcode scanners act as a second keyboard, that is they emit text as
if it was typed. With often the option to prefix and append two selectable literal strings,
so you can differentiate a scan result from simple typing.

Dim body As String = "Here is a picture of CRM:
Dim av1 As AlternateView = AlternateView.CreateAlternateViewFromString(body, Nothing, "Text/Html")
Dim linkedResource1 As LinkedResource = New LinkedResource(ms,?????)
linkedResource1.ContentId = contentId
av1.LinkedResources.Add(linkedResource1)

It sends image with mail PERFECTLY....
but now I have to send mail which is store in memory stream .
not in file...
I have code
like
How can I send the image wich stored in memory stream ???
I have code
like

Dim ct, ct1 As New ContentType
Dim ct2 As New ContentType("image")

Try this instead:
Dim ct As New ContentType
Dim ct1 As New ContentType
IIRC, your way of definition means that ct is untyped in VB...

I'll try to explain :
look this example :
Module
Module1
Sub Main()
Dim num AsDouble = 1.25
Console.WriteLine(Math.Round(num, 1, MidpointRounding.AwayFromZero))
num = 1.225
Console.WriteLine(Math.Round(num, 2, MidpointRounding.AwayFromZero))
num = 1.2225
Console.WriteLine(Math.Round(num, 3, MidpointRounding.AwayFromZero))
num = 1.22225
Console.WriteLine(Math.Round(num, 4, MidpointRounding.AwayFromZero))
num = 1.222225
Console.WriteLine(Math.Round(num, 5, MidpointRounding.AwayFromZero))
num = 1.2222225
Console.WriteLine(Math.Round(num, 6, MidpointRounding.AwayFromZero))
EndSub
End
Module
The output of this sample console application is :
1,3
1,23
1,223
1,2223
1,22222
1,222223
Is there something wrong ?
In my application I must use five decimal digits and this round method.

No, there isn't anything wrong with the Round method. The problem is your expectations on the double data type.
You think that you are putting the exact value 1.222225 in the variable, but that number (as most numbers) can not be exactly represented as a double. What you are actually putting in the variable is something very close to that value, something like 1.22222499999834, which does of course round to 1.22222.
Despite everything, the person most likely to be fooling you next is yourself.

Is there any function to increase a double by the smallest possible non-zero amount? I would expect one could do something like:
Function BumpDouble(ByVal Num As Double) As Double
Dim Delta, NewVal As Double
Delta = Num / 36028797018963968 ' (2^55)
If Delta <> 0 Then
Do
NewVal = Num+Delta
Delta *= 2
Loop While Num = NewVal
Else
' Need special handling for really really small numbers
End If
Return NewVal
End Function
But that seems a bit hokey.

Rather than try to compute Delta, use Double.Epsilon instead - then you could just do Num + Delta.

Stuart Dootson wrote: Rather than try to compute Delta, use Double.Epsilon instead - then you could just do Num + Delta.
The smallest delta value for a given number will only equal Double.Epsilon if the number is very close to zero. In practice, it will always be equal to either the number divided by a particular power of two, or (if that division yields zero) Double.Epsilon; any assumption about the power of two in question, however, may break portability if future machines support higher-precision numerics.

You could try using the DECIMAL type instead of DOUBLE. It is much more accurate, however, a bit slower in use. This should get rid of most of these errors as explained by Guffa

It looks to me liek the round function is working correctly
for example for three decimal places
1.2225
since the last digit is 5 the number is rounded up to 1.223
my understanding of round is that a number is rounded down if the digits past the rounding point is 00 <= digits < 50
and rounded up if the digits past the rounding point is 50 <= digits < 100

You are missing the point. Notice the value 1,22222 that seems to be rounded differently from the others.

Yeah actually single(float) and double are working the same way, it's not precise, because it's floating-point numbers representation. So it's a lot better and precise to use fixed-point number representation = Decimal in .Net

Use integer math with normalized integers and there is no problem.
Added bonus - it's a gazillion time faster than floating point math.
Divide by 10^5 before displaying to humans.

The Round method does not use what most of the community expects the Round method to use with regards to its function. The reason being is because the Round method rounds to the nearest even integer, in a link following you will see it is termed: the bankers method. The Round method has two options: MidpointRounding.ToEven or MidpointRounding.AwayFromZero. Neither of these is exactly what a user may want to see. You may find a better here[^], at this URL (found by google) their is a custom function that should round based on what most of the community expects. I have no idea why Microsoft chose non-standard forms of the Round function.

i have a web application that uses role/membership provider.i design the menu according to dep/role like
HelpDesk Account Stock Admin
enqury daybook jobbin createuser
appiontment balance mandate removeuser
caution updateuser
setup info
at present i can only a sign role base only. that is somebody in helpdesk will use only the submenu under hlpdesk.
i can also make sombody to be multiple role.
question
1 how can be able to deny a person in account for example access to balance submenu. that assign access on pages basis
2 load menu base on user right
any suggestion will be appriciated

Assuming your are using ASP.NET and your user permissions are stored in a database table, you would need to add your menu control with no options to your webpage/usercontrol and then in the Page.Load event add the options to the menu in accordance with your user's permissions, but only if IsPostBack = False

I am designing an application that will be able to read and write XML files. The XML Files use XML formatting with a Document Type Definition.
Example:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE scheme SYSTEM "scheme.dtd">
<scheme date="20060312">
<title>Example Scheme</title>
<description>This is an example scheme</description>
<drawers>
<drawer id="d1" label="Drawer 1"/>
<drawer id="d2" label="Drawer 2"/>
<drawer id="d3" label="Drawer 3"/>
<drawer id="d4" label="Drawer 4"/>
<drawer id="d5" label="Drawer 5"/>
<drawer id="d6" label="Drawer 6"/>
<drawer id="d7" label="Drawer 7"/>
<drawer id="d8" label="Drawer 8"/>
</drawers>
</scheme>
I haven't ever worked with XML in VB.. (Either VB6 or .NET)
I am using VB.NET 2005.
I need to be able to read the attributes into text boxes dynamically.
The number of Drawers is Dynamic so it could be anything from 1 to 1000.
Each row would need to contain the ID and Label. Sort of like a grid view.
Does anyone have any pointers on where I should start? I can load the XML file and show it in a treeview or a single textbox, but I cannot seem to figure out how to pull the attributes only. I know the XML file is strange since it uses no Text between brackets, just attributes inside the brackets.
Thanks,
Andrew Streetman
