I'm writing a small program and I ran into a problem. I want to append text to RichTextBox every 1 Timer Tick. How can I do that?
Ok...handle the Tick() event of the Timer and append your text:
Private Sub Timer1_Tick(sender As System.Object, e As System.EventArgs) Handles Timer1.Tick
RichTextBox1.AppendText("Append: " & DateTime.Now & vbCrLf)
End Sub

I created a Macro with Microsoft Word 2010:
Sub Macro1()
Selection.WholeStory
End Sub
At the event Button1_Click I would execute the macro :
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Selection.WholeStory
End Sub
I remember that Visual Basic 6 allowed to enter Macro object from Microsoft Application.
Now with Visual Basic 2008 Express Edition?
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click

I am trying to make a calculator on visual basic application forms and I have most of the codes sorted. How do I make it so when I press the number button, it puts the number in the text box. It also needs to be able to work so if I pressed 1 then 2 then 3, it appears a 123.
Just set the SelectedText() property of the TextBox to the Text() property of your button.
For example:
Private Sub Button1_Click(sender As System.Object, e As System.EventArgs) Handles Button1.Click
TextBox1.SelectedText = Button1.Text
TextBox1.Focus()
End Sub
If you make all the buttons fire the same handler, then it becomes:
Private Sub AllButtons_Click(sender As System.Object, e As System.EventArgs) _
Handles Button1.Click, Button2.Click, Button3.Click, Button4.Click, Button5.Click, _
Button6.Click, Button7.Click, Button8.Click, Button9.Click, Button0.Click
Dim btn As Button = DirectCast(sender, Button)
TextBox1.SelectedText = btn.Text
TextBox1.Focus()
End Sub
When I use an OpenFileDialog, and select a file and click open etc, etc...
I want a label on the same form to automatically update with the directory path. At the moment I have this working, However the label updates on click, not automatically on the directory change.
CODE:
Private Sub Label4_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Label4.Click
Label4.Text = OpenFileDialog2.FileName
End Sub
Cna I change the "Label4_Click" to something else for an auto update?
How are you displaying the OpenFileDialog? You need to update the Label from there!...
Something like:
Private Sub Button1_Click(sender As System.Object, e As System.EventArgs) Handles Button1.Click
If OpenFileDialog2.ShowDialog = Windows.Forms.DialogResult.OK Then
Label4.Text = OpenFileDialog2.FileName
End If
End Sub
This code is throwing TwitterAPIException on this line
profilepic.ImageLocation = twitter.AccountInformation.ProfileImageUrl
I have a feeling it may be because it isn't authenticating but I'm not sure. any idea why i might be getting this, also how can i in my code check if twitter has authenticated me before trying to actually read data?
I have removed the private keys for privacy
Imports TwitterVB2
Public Class Form1
Dim twitter As New TwitterAPI
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load

twitter.AuthenticateWith("", "", "", "")
profilepic.BackColor = Color.White
profilepic.ImageLocation = twitter.AccountInformation.ProfileImageUrl
tw_name.Text = "HI" + twitter.AccountInformation.Name
For Each Tweet As TwitterStatus In twitter.HomeTimeline
tweets.AppendText(vbNewLine + vbNewLine + Tweet.User.ScreenName + vbNewLine + Tweet.Text + vbNewLine + Tweet.CreatedAtLocalTime + vbNewLine + vbNewLine + "..............................")

I'm the developer of TwitterVB. :)
Because I stopped updating the library in 2011, TwitterVB was never updated to work with version 1.1 of the Twitter API. I've gotten many, many requests to address this specific issue, so I have made an updated version of the DLL available here:
https://github.com/DWRoelands/TwitterVB/releases/tag/3.1.1
Please note that I have done no testing and that this DLL should be considered "pre-release". If you have questions or issues, I'll do my best to answer them. You can reach me via my GitHub page:

I am trying to write 2 simple subroutines in VB 2010 that could be used with toolstripbutton contorls for multiple textboxes in a form. I know simple copy paste could be done using the textbox1.Copy() and TextBox1.Paste() methodes. What i am trying to do is write a common subroutine which could be used on any textboxes in the form not just one particular textbox.
My codes are below, I know there are errors in it, just wondering how it could be achieved. Any help would be highly appreciated. Thanks.
Public Class Form1
Private Sub copytext()
Dim txt As Control
If TypeOf txt Is TextBox Then
Clipboard.Clear()
Clipboard.SetText(txt.SelectedText)
End If
End Sub
Private Sub pastetext()
Dim txt As Control
If TypeOf txt Is TextBox Then
txt.Text = Clipboard.GetText
End If
End Sub
Private Sub mnuCopy_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles mnuCopy.Click
Call copytext()
End Sub
Private Sub mnuPaste_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles mnuPaste.Click
Call pastetext()
End Sub
End Class
