What happens here is when I click on anyone of the radio buttons the text box score sets the value to either 0,1,2,3,4 but when I go the next case it goes back to 0 instead of keeping the value. I tried many different techniques while going about this none seem to work.

My application outputs log text every so often and I need the user to be able to see the latest text at all times. I've tried a label, a text box and a rich text box, but I can't figure out a way to show the bottom-most text at all times.
View 2 RepliesI would like to make a simple code that counts the top three most recurring lines/ text in a txt file then saves that line/ text to another text file (this in turn will be read into AutoCAD's variable system).Forgetting the AutoCAD part which I can manage how do I in VB.net save the 3 most recurring lines of text each to its own text file see example below:
Text file to be read reads as follows:
APG
BTR
VTS
[code]....
The VB.net program would then save the text VTS to mostused.txt BTR to 2ndmostused.txt and APG to 3rdmostused.txt?

I've never really used the SecureString class before but I've got a requirement in an app to have a user enter a password that will be used later in the application, and I figure SecureString is the most secure way to do this.
I have created a little dialog form where the user will enter their username and password and have set the UseSystemPasswordChar property of the password textbox to True. As I need to keep the password in memory for use later though, I have created a property in my main form that is of type SecureString and when the user enters their password into the dialog window I copy the string from the password box to the SecureString property like so:
vb.net
For i As Integer = 0 To LoginFrm.PasswordBox.TextLength - 1
Me.ConnectionPassword.AppendChar(LoginFrm.PasswordBox.Text(i))
Next
I figured out how to get the original string back when I need to (with only a slight hint from the documentation I might add ), which I do like this:
Dim OriginalString As String = Marshal.PtrToStringBSTR(Marshal.SecureStringToBSTR(Me.ConnectionPassword))
but the problem I have is that I want the user to have the option to edit the password they already entered if they want to. This is a problem because I want to avoid putting the real password back into the password box for security reasons, but then if I just put some random characters in there (just to show that their password has been remembered by the app) and then the user clicks OK on the login diaog form then it will update my ConnectionPassword property and set it to the random characters.
One option would be to set the passwordbox text to something specific each time and then test to see if that is what the text is set to when they click Ok (and if it is then obviously dont update the ConnectionPassword property) but this seems pretty rubbish because its possible (however unlikely) that the user could actually select that word as a password.
Any better suggestions? Perhaps its not worth doing anything at all and just use a normal string as the SecureString is going to have to get converted back to a normal string at some point to be used.
Public objword As New Word.Application

Dim oDoc As Word.Document
objword.Visible = True
oDoc = objword.ActiveDocument

This gets the document and adds text into it, exactly what i want it to do. But it replaces the whole document. I just want it to add text at the start of the document. Not replace the whole document.
I am building a sort of 'lightweight' Visual Studio, and I'm trying to implement the feature where you can drag tabs to different 'tab groups', viewing multiple tabs side by side.
I got nearly everything working, I show a ContextMenuStrip when you rightclick the tab headers, with the option of creating a new (horizontal or vertical) Tab Group. When that happens, a new TabControl is added dynamically and the selected tab is moved there. You can drag the tabs around inside a TabControl and even from one to another.
The problem now is keeping track of the 'active' tab. Since I have multiple TabControls (not just two, there can be as many as you want theoretically), their SelectedTab properties are basically useless. How am I to determine which TabControl the user is currently working in? Obviously I will always have multiple selected tabs, but only one active tab, in which the user is currently typing, editing, whatever.I need to know the active tab for obvious reasons: many menu and toolbar items act on the active tab for example. A short explanation of my controls:I have one TabGroupContainer control, which inherits UserControl. I have a TabGroup control, which inherits TabControl.I have a Tab control, which inherits TabPage.
The TabGroupContainer holds a collection of TabGroups (to which I dynamically add/remove TabGroups when required). Now I want the TabGroupContainer control to have the ActiveTab property which returns the one and only active tab (out of possibly many selected tabs).The only logical way is to keep track of the tab that was selected last, for every TabGroup.
At the moment, I am doing this:
- In the TabGroup (TabControl) class, I shadow the SelectedTab property (and return a Tab instead of a TabPage). More importantly, in the property setter, I raise a SelectedTabChanged event:
vb.net
Public Shadows Property SelectedTab As Tab
Get
Return DirectCast(MyBase.SelectedTab, Tab)
[code]....
However, it still doesn't work. I soon figured out why: I am checking that the previously SelectedTab is not the same as the new value in the property setter of the (shadowed) SelectedTab property. I don't raise the event when they were the same, and in this case they were the same (as there is only one tab in the TabGroup!).So, I took that check out, and now it seems to work when I click in the text editor.
So one problem remains: the active tab is not changed when you click on the tab header (and not on the text editor). I am clueless as to how I should handle this... I am once again sure there is a simple fix, but I cannot see it. I can click the tab header, and I'm sure behind the hood it responds to this click, but it never raises it SelectedIndexChanged event because the index didn't change but was set to the same value it already had. I cannot override the SelectedIndex property (so I could skip this check and raise the event anyway even if the value didn't change), and the OnSelectedIndexChanged method is not called, so I cannot use that either...
(Currently using VB.NET 2010 Express) I'm trying to make a program, the main of which is file transfer. I'm trying to create a program that will keep files and folders synchronized across multiple client computers. I'm using a File system watcher to trigger events, and Using a simple System.Net.Sockets UDP client transfer (found via google) to transfer commands between it and itself on other computers.
Here's that code (this just sends from one textbox to another over the internet)
Imports System.Net.Sockets
Imports System.Net
Imports System.Text
Dim udpClient As New UdpClient(1024)
Dim RemoteIpEndPoint As New IPEndPoint(IPAddress.Any, 0)
[Code] .....
By this method, I can rename, move, or delete files. I want to implement file transfer, so that whenever a new file is created, or updated, my program will automatically transfer the file to the other computers and update them there.
I have a ton of questions that I cant seem to figure out in regards to VB Script.
1. How do you convert text in a text box to Upper Case?
2. How do you write the code to display messages in a Label box?

I have a series of text fields on a simple form (inside a group box) I would like to enforce all the text be upper case upon submission to the database. I know I can use the Ucase command. The question is implementation. How can I very efficiently force all the field values to upper case vs. say doing Ucase(TextBox1), Ucase(TextBox2).... ( I have 12 fields in this case) Is there a way to treat the text boxes as a collection and do it in one shot? Just trying to be very efficient and create clean, tight code even on such a simple thing.

When my form loads it adds some handles (using AddHandler) to a sub (showStatus). What this sub does is checks which control activated the sub (using sender.Equals) and displays text in the status label (status) accordingly.For this I use an If...Then statement for each possibility. There are many possibilities and my code get cluttered. Is there a way to do the same thing with a Select...Case statement. I tried: Select Case sender Case tbOne : status.Text = "blahblahblahblahblahblah" End Selectwhere: tbOne is a textbox, status is a StatusLabelIt gives me an error though, saying "Operator '=' is not defined for types 'Object' and 'System.Windows.Forms.TextBox'."Any ideas on how I can get this to work with a select case statement?
