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
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
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)
Selected()
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
End If
End If
Next
End Sub

Thanks for those nice tutorials.

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 ?
|
|
|
|
|
|
so ... is your question answered now ?
|
|
|
|
|
Yes. And I solved it out as I mentioned in my previous reply.

You can see what it does. Alternatively you can run the code and watch it happening.
|
|
|
|
|
I run the code (F5) but I can't see what it actually does.
|
|
|
|
|
Then you need to compare the workbook before and after, and check that all parts of the code are working correctly.

Try using F8 and going through it step by step

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.

Uhm why not read in the string and use string.replace() or am I missing something?

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!

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.

That is a bad way to do it, and can lead to corruption of your files. A much safer option is to use two files, one for input and one for output. Read the input file and copy the content to the output, replacing the required characters in memory as you copy. When you have successfully copied all the data you can delete the input file, or rename it to save as backup. You can then rename your output file to the original name of the input.

Good observation, but would be not preferable for a crypto chat read and write continuously wholly key file (size about 10 Mega) when just overwrite the first part of the file. I seek only a comfortable way to synchronize key file between broadcaster and receiver.

|
|
|
|
Fine, do it your way. But make sure you test your code to destruction before you use it on live data.
|
|
|
|
|
You could use a second file for just storing the position from where to read the next OTP-characters and leave the OTP-file unchanged.

Hi,
I have a fileupload control on a web form, along with an upload button and a radio button list of file types.
There exists the possibility that the user could click the upload button before selecting a file in the fileupload control which would generate an error message that would be displayed asking them to select a file first.
The issue is; if this situation occurs, the message remains on the screen, even after they select a file.
Is there some way to add a reset method to this control, so the previous error message gets cleared when the fileupload control is selected?
I tried a few things already and as you can probably guess, they all failed.

Yes, but it kind of depends on how you've implemented it so far. But basically add an onfocus (JavaScript) event to the fileupload control and in that clear the message - to do this you'd obviously need to first of all make sure its been written to a DOM element you can access.
