I have not seen this code-part before - please excuse me.

But : from where comes the content of the Variable (?) "weightRequested"

I still think that more Information could be very useful ...

VB6: Resource Editor shows no resources [SOLVED]

I've inherited a VB6 project that uses resources, and they work fine, but when I open the resource file with the resource editor, there are no resources there! Googling hasn't turned up any similar problems.

Anyone have an idea how to get access to the project's resources? Thanks!

I want to build a Font Designer Application in VB.NET. With which we can create or designed new type of fonts. But I can't understand what will be the starting point?

The logical starting point would be to research and understand font files, their format and how they are created.

The difficult we do right away...
...the impossible takes slightly longer.

Hi am working on new website with 2 languages only
so far i have succeeded to do it as this

MasterPage on Page_Init event

VB.NET

If (Session("culture") IsNot Nothing) Then
            Dim ci As New CultureInfo(Session("culture").ToString())
            Thread.CurrentThread.CurrentCulture = ci
            Thread.CurrentThread.CurrentUICulture = ci
        End If

ManagerBase Class OnInit event

If Session("culture") Is Nothing Then
            Dim languages() As String = HttpContext.Current.Request.UserLanguages
            If ((languages Is Nothing) OrElse (languages.Length = 0)) Then
                Session("culture") = "en-US"
            Else
                Session("culture") = languages(0).ToLowerInvariant.Trim
                If Session("culture").Contains("ar") Then
                    Session("culture") = "ar-SA"
                Else
                    Session("culture") = "en-US"
                End If
            End If
        End If

Change Language Event

If Thread.CurrentThread.CurrentCulture.IetfLanguageTag = "ar-SA" Then
            Session("culture") = "en-US"
            MyBase.OnInit(e)
            Server.Transfer(Request.Url.PathAndQuery)
        Else
            Session("culture") = "ar-SA"
            MyBase.OnInit(e)
            Server.Transfer(Request.Url.PathAndQuery)
        End If

the thing is when user choose another page or select different view in the page he lose the culture he selected it

how i can fix it?

I have two form, Form2 contains dynamically created checkboxes and Form1 has a textbox(TextBoxSelected). I add event handler to the checkboxes that count the total number of checked chekboxes. Now I want to pass the count value to the TextBoxSelected.
CheckBox Code in Form2

VB.NET

Public Sub CreateCheckBox(ByVal _filename As String, ByVal _displayname As String)
        Dim checkBox = New CheckBox()
'------------ '  
'--------------'
        checkBox.Size = New Size(117, 109)
        checkBox.Text = (_displayname)
        checkBox.Image = resized
        checkBox.BackColor = Color.Gray
        checkBox.ForeColor = Color.White
        checkBox.TextAlign = ContentAlignment.BottomCenter
        checkBox.Location = New System.Drawing.Point(XcLocation, YcLocation)
        AddHandler checkBox.CheckedChanged, AddressOf myhandler2
End Sub

Private Sub myhandler2(ByVal sender As System.Object, ByVal e As System.EventArgs)
        'Dim cb As CheckBox
        'cb = CType(sender, CheckBox)
        Selected()
        'MsgBox(SelectedCount)      
End Sub

Private Sub Selected()
        Dim count As Integer
        count = 0
        For Each ctrl As Control In Me.Controls
            If TypeOf ctrl Is CheckBox Then
                If DirectCast(ctrl, CheckBox).Checked = True Then
                    count += 1 'this will count the checked checkboxes

                End If
            End If
        Next     
End Sub

Now ... what is your question ?
I think, that your code which count the checked Checkboxes is working.
Don't you know how to find out, which Textbox is actually selected ?

Then you need to compare the workbook before and after, and check that all parts of the code are working correctly.

Extract text in a file txt and simultaneously replace it with dots.

Hi, i am working in VB 2010 an a one-time pad software.
The problem is the following. I have a txt file with many continous characters like this "KHKJHDKJDHAKHDAKHDAKHAKDHADHAKJDHASJDHA", i need to read a variable number of this characters and after replace it with a same number of dots (Ex. "zxsd" replaced with "....").
Now, with this code i can read the characters from specific position:

Using stream = File.OpenRead("c:\key.txt")
stream.Seek(v, SeekOrigin.Begin) ' v = startup position for read in file key.txt 
Dim b = New Byte(a - 1) {} ' a= lenght of text in key.txt to be taken)
stream.Read(b, 0, a) 
Dim str = Encoding.ASCII.GetString(b)
txtPad.Text = str
End Using

But how i can do for replace text extracted with dots without delete any line?

Why would there be line breaks in the OTP file which aren't meant to be part of the OTP data? Doesn't make much sense to me - if you're at liberty to change that, I would recommend to do so.

First, you'll have to open the file for read/write access instead of read-only. Then, after reading your OTP string, you'll have to seek again to the position where you started to read it. Then you'll have to write the replacement-string there. There's more than one way to do this - one way would be to convert the source string into a char-array, loop over the characters in that array and write a dot to the file for every character that isn't part of a line break and write line-break characters unmodified to the file.

For that he would have to have the substring-data that should be replaced as a string but it shouldn't be needed as a string for any other purpose, if I'm interpreting things right. Instead he should be looping over the single characters anyway in the encryption part.

Hi Sascha, let me explain better, my project is a Vernam chat and i need to have one single keys txt file that must remain synchronized in some way between broadcaster and receiver. When I send the message the key used must be deleted and who receives after decripting too. I thought at line numbers of string to identify the key location, but I am open to other solutions.The goal is synchronizing the two key files! Confused | :confused:

Imagine your OTP file is just a sequence of bytes (or ASCII characters if you like). The message you want to encrypt is 100 (ASCII) characters long. The sender reads the next 100 characters from the OTP file, encrypts the message and sends it. The receiver sees 100 encrypted characters and also reads the next 100 characters from the OTP file to decrypt the message. Both sender and receiver know the length of the message, so they can update the position from where to read the next OTP-characters by the same amount. No line numbers needed.
