It seems your making a mistake in providing the arguemnts for your max scroll.
Quote: Private Sub Form1_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
scrollhandler = New MyListener(FlowLayoutPanel1)
maxscroll = CalcMaxScroll(FlowLayoutPanel1.Size.Height, FlowLayoutPanel1.Size.Width, 114, 1075, 19)
'19 number of tweets
'114 height of tweettimelinecontrol
'1075 width of flowlayoutpanel1
'last number tells the number of items. (read that from a global var)
End Sub
You say that the with of your flowlayoutpanel is 1075. yet you apply it to the formula as the with of your tweettimelinecontrol. quoting you from a previous post:

Oh that kinda worked... but how am I ganna calculate the value in a control like this one:
When its normal screen size:
http://foto.pk/images/minx.png[^]
you can see in the screenshot that you got 2 of those controls next to eachoter so it can never be the total size of your flowlayoutpanel. please check the with property of your Tweettimelinecontrol and change the value. while your at it also change the 19 with a flowlayoutpanel.items.count to make sure it are 19.

private int previousValue;
public void someEventHandler(...) {
int currentValue=...;
if (currentValue==extremeValue && currentValue!=previousValue) doWhatEver();
previousValue=currentValue;
}

oeh quite nice! might actually try that in the future. but isn't that C#?

I'd call it pseudo-code around here

isn't previousValue a readonly value?
|
|
|
|
|
did I declare it read-only?

Seems like I misunderstood the algorithm.

Hi everyone,
I am currently working on developing some code for transfer file from one pc to another. As I read in lot of article, those work can be done by FTP concept.
I'm using win7 and VB.NET 2010
I've got some simple source code for uploading a file, but I'm experiencing a problem which describe below
System.ArgumentNullException was unhandled
Message=Value cannot be null.
Parameter name: type
ParamName=type
Source=mscorlib
it's refers to:
ITCObject = Activator.CreateInstance(ITC)
Here are the source code:
Imports System.IO
Imports System.Reflection
Imports System.Threading
Public Class Main
Private Sub btnBrowse_Click(ByVal sender As System.Object, e As System.EventArgs) Handles btnBrowse.Click
OpenFileDialog.ShowDialog()
tbFile.Text = OpenFileDialog.FileName
End Sub
Private Sub btnUpload_Click(ByVal sender As System.Object, e As System.EventArgs) Handles btnUpload.Click
Dim thisFile As FileInfo = New FileInfo(tbFile.Text)
Dim ITC As Type
Dim parameter() As Object = New Object(1) {}
Dim ITCObject As Object
ITC = Type.GetTypeFromProgID("InetCtls.Inet")
ITCObject = Activator.CreateInstance(ITC)
parameter(0) = CType(tbRemoteServer.Text, String)
parameter(1) = CType("PUT " + thisFile.FullName + " /" + thisFile.Name, String)
ITC.InvokeMember("execute", BindingFlags.InvokeMethod, Nothing, ITCObject, parameter)
End Sub
End Class
is there anyone could help me to resolve this problem.
Thx,
Phann

That means:
ITC = Type.GetTypeFromProgID("InetCtls.Inet")
returned null.
But tell us: why do you need Refelection for FTP?

what do you mean by Bernhard Hiller wrote: Refelection for FTP?

I'm really not quite sure.. but it came with the source code.. and it has related with "BindingFlags.InvokeMethod".
I'm still having difficulty to figure out the source code and how it works..

Compare your code with the sample here[^].

[b]Hello everyone.[/b]
I am trying to create a basic project in vb.net. In this project i have a richtextbox with name editingarea and a button with name button1.
I just want that when the button1 is clicked a font selection dialog box will open where the user can select the font name and size. then set this font for rich text box.
But I am getting some kind of error as "Property name is read only", "Property size is read only", after setting the readonly property to false too.
Here is the code
If SelectFont.ShowDialog = Windows.Forms.DialogResult.OK Then
EditingArea.Font.Name = SelectFont.Font.Name
EditingArea.Font.Size = SelectFont.Font.Size
End If
Can someone help me out.
[b]Thanks[/b]

Some Properties of a Font cannot be changed after construction. But you can set the "whole" font:
EditingArea.Font = SelectFont.Font
|
|
|
|
|
I want to change all properties of fonts such as name, size, fore-color, back-color, bold, italic as the user wishes.
Can U tell me that how should I go. O can you provide me some code snippet for the same.
Thanks

Once a Font object is created you cannot change any part of it.
So, the only way to get around this is to create a new Font object and set the Font property of the RichTextBox.
Dim newFont As New Font(fontName, fontSize, fontStyle)
myRichTextBox.Font = newFont

You're thinking like a user in terms of what you want. You can't set the individual properties of a font, you'll have to create a new object with the properties that you need;
richTextBox1.SelectionFont = new Font(richTextBox1.Font,
richTextBox1.SelectionFont.Style ^ FontStyle.Bold);
It might be working exactly as the user expects as you're not changing a property, but creating a new object with the correct properties. Same goes for the other properties; if they're readonly, you'll probably have to replace the entire object.

Tsk Tsk! Posting C# in the VB.NET forum. Talking about dangling a carrot and pulling it away when they bite for it!

Just put "replace brackets and semi-colons by verbose keywords when appropriate" in your sig, and all will be fine.

Hello everyone, currently I am working on a project, in which I have save some text, and images on disk in encrypted format (means no other application except mine may be able to read). But I have never worked before on such project (means creating a new file extension for some special purpose, on data encryption). So I am bit confused about it.
So can U please help me in this respect, or point me towards some good tutorial which can help me.
Thanks
