How To Autoscroll In Textbox?
Nov 18, 2009
I am currently making a DOS type thing, called the Terminal Client, in visual basic 2008 express. I have 2 textboxes, one is a big multiline textbox for where all the command stuff goes. Then I have a second textbox at the bottom thats not multiline, and thats just for typing commands. I want to make the big multiline one scroll down as you put more and more commands into it.Something like this (which ive already tried):
textbox1.selectionstart = textbox1.text
textbox1.selectionlength = 0

I have a multiline textbox that while a file is read in some data is echo'ed out onto the textbox. Is is possible to programatically scroll the object down to the bottom? Changing everything over to a combobox and then changing the selected index would essentially do what I want, but the user needs to select/copy a bunch of lines.

I am using a panel control in vb.net (2010) to build a timeline of images. These are very small images (320x180) and I am running into a limit of 240. While the panel does not complain when I add more - it will only scroll to the 240th one.[code]...
I am counting on some of the built-in functionality of the panel in autoscroll mode (being able to bring any of the thumbnails into view), etc. I am certainly not averse to purchasing a third party control for this. I really need to be able to display 1000 or more thumbnails!

I have a program that will keep adding info to a richtextbox, I want to to autoscroll to the end
this is what I have vb.net Private Sub RichTextBox2_TextChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles RichTextBox2.TextChanged RichTextBox2.SelectionStart = RichTextBox2.Text.Length - 1 RichTextBox2.ScrollToCaret()
Return
End Sub
the problem is that it will go back to the beginning of the richtextbox2 then it will go to the end and it keeps jumping like that. If there a "smoother" way to do this? So it wont keep jumping back and forth?

I have a program trying to use mousehover to pause the autoscroll. It is a widows form called:
lstOutput System.Windows.Forms.1 Below is how it is in my code.
Public Sub lstOutput_MouseHover(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles lstOutput.MouseHover
'Public EventMouseHover As EventHandler
lblPauseScroll.Text = "Output Paused" 'display output paused
'Highlight the DataGridView
Me.lstOutput.BackColor = Color.LightGray
[Code] .....
For some reason I have to click on the form to get it to pause the first time and then after that it does pause when I place the mouse over the form. It is that first time that it won't pause. The Public Subs I hand typed the codes in, is there some way that I should have added the mousehover to the form itself or are there other reasons that it won't work the first time?

I've recently decided to take a huge leap and migrate from my good old VB 6.0 to VB.NET, since VB 6.0 was proved to be fairly insufficient for my needs. So, I took a deep breath, loaded myself with a lot of patience and...here I am!The transition from VB 6.0 code to VB.NET seemed quite buffling in the beginning, but later on it proved to be pretty straightforward.So, now, I've decided to get my feet wet and develope my first VB.NET appication.The reason I'm here is that I would like an evaluation of my first code snippet in terms of efficiency, productivity and so on.
A description of what I'm doing is this: On a Windows form, docked at the left side, I have a panel set to AutoScroll. Inside it I've placed a number of panels, each one with a ToolStrip, having a button to collapse or expand the panel.It works so far, but I don't know how efficient my code is. Here is the code of a generic Click Event that handles the clicks of all toolstrip buttons.Each button has a Tag to indicate the state (expanded or collapsed) and each panel has a numeric tag for the height it would have when expanded.
Here is the code.
Private Sub Buttonclick(ByVal sender As System.Object, ByVal e As System.EventArgs) _
Handles TSB_1.Click, TSB_2.Click, TSB_3.Click, TSB_4.Click, _
TSB_5.Click, TSB_6.Click
[CODE]...
So...what I would like to have is an evaluaion of this small code. It seems to be a bit larger than the code I could write in VB 6.0 and I'm sure that there is a better way.

The following code works perfectly to allow moving a control on a form at run-time. However, when AutoScroll is set to True on Form1, and you drag Button1 past the right and/or bottom bounds of the form, it goes haywire. I really need someway to smoothing control the autoscroll so that as you scroll the control off the form, the scrollbars smoothly appear.

This is for a mapping/plotting program.
t.panel is the main panel and it has too much content to fit in one screen so there are scroll bars. x.panel contains the horizontal scale for the data points in t.panel. I drew the scale using a bitmap and set it as x.panel's background.
Setting x.panel's horizontalscroll.value = t.panel's horizontalscroll.maximum doesn't seem to work. I think this is because x.panel's doesn't have any content that causes it to need scroll bars.

Is it possible to have a Textbox on a form that when the user inputs data, ( during Runtime )that data remains in the Textbox for good and the Textbox then becomes read only ? Is it also possible to make it so that the CD with the programme on, is in the PC when the programme is being used. Perhaps writing the Textbox data back onto the CD ?

I have a TextBox in a Windows Forms application in VB 2008 (.NET 3.5) where a user can key an estimate amount. I am allowing them to key dollars and cents, and I want to round to the nearest dollar. The original code had the rounding down when the data was written back to a table, and that worked fine - I have this code in a "Save" routine that fires when the user moves to a different screen or record:
Dim est As Decimal : Decimal.TryParse(txtEstimateAmount.Text.Trim, est)
Dim estimatedAmount As Integer = Math.Round(est)
I decided that it might be nice to actually do the rounding as soon as they leave the field instead, so they're not surprised when they reload the screen and find that 1822.60 is now 1823. So I took the exact same code and added it to the TextBox.Leave event handler. And the weirdest thing happened: instead of the variable est being populated with 1822.60 after the parse, it gets set to -1! What the...?
Debugging the handler shows that the value goes into the parser correctly, and if I do the parsing manually via the Immediate window, it parses correctly, but when I let the code do it, it invariably gets set to -1. What's even weirder is that any number gets parsed as -1, not just decimals, and any non-number gets parsed as 0 (which is correct).
Has anybody else ever run into this before? I tried moving the code to the TextBox.LostFocus event instead, but with the same results. I have no idea what in the heck is going on, and obviously there are workarounds galore for this, but it just makes no sense whatsoever.
EDIT: Here's the full event handler (current behavior for which is to put -1 in the TextBox):
Private Sub txtEstimateAmount_Leave(ByVal sender As Object, ByVal e As System.EventArgs) Handles txtEstimateAmount.Leave
' Take any dollars-and-cents amount and round to the nearest dollar
Dim est As Decimal

I have a database I am creating with about 50 users over a network. There are about 6 groups of users and these users are spread across 10 branches. I want to block/allow users from particular forms and views. For example I want branch users forms to be filtered by their branch number but depending on the group they are in they can only see some forms. i.e. 50 users, 10 branches, each branch has about 5 ppl of where 1 is in group A and 4 are in group B. I want all users that belong to branch 1 to see the information they enter, but Group B enter data but cannot approved or delete, and group A can enter, approve and delete. So then. On my login form I have the user type his/her username but the i want LEAVE function to update 2 textbox where I have named GroupName and BranchNo. Basically to run a query and look for the username and return in one textbox that user's groupname and the other textbox the user's branch no. This information will be used to filter forms and block the user from certain controls. This is the code I have so far but still can't figure how to display the results.
Private Sub UsernameTextBox_Leave(ByVal sender As Object, ByVal e As System.EventArgs) Handles UsernameTextBox.Leave
'Make Connection to database
[Code].....
It keeps highlighting the BranchNumber and UserGroup and giving error "Value of type 'String' cannot be converted to System.Data.OledbCommand

Below is the code i have so far: BTW FLP is my flow layout panel and c is my calculated nmber of textboxes that are created.
