Be aware that all string or numeric comparisons must be between the same type: 1. Number compared to Number or 2. String compared to String. Never Number compared to String, or String compared to Number. Line# 9: If ComboBox3.Text.ToString >= 1 <= 10 Then compares ComboBox3.Text.ToString, i.e. a String, with …

Why not just supress the traling `.toString` and set value as an `Integer`? Private Sub Timer1_Tick(sender As Object, e As EventArgs) Handles Timer1.Tick Dim value As Integer = CInt(Label10.Text) If value >= 1 And value <= 30 Then value -= 1 Else If value <= 0 Then Form11.Button5.PerformClick() Timer1.Stop() End …

You may add a `timer` and in `Timer.tick`event call to `Button5_Click(sender, e)`. BTW, number 365 in line#7 is numeric and `dysdiff`is a string, so it's not possible the substraction to work.

Are you asking for this?: For Each prop As System.Configuration.SettingsProperty In My.Settings.Properties prop.DefaultValue = "" Next

Try renaming `size`, for example `sz`.

Line# 41 should be `tennis`, isn' it? Also, `n1, n2, n3` and `total` aren't intialized to zero.

You may do: Public Sub Btn_Click(sender As System.Object, ByVal e As System.EventArgs) Try Dim btn As Button Dim cbx As ComboBox Dim txt As TextBox Select Case sender.GetType Case GetType(Button) btn = CType(sender, Button) ' TODO ...

Employ `CheckChanged` event: Private Sub CheckBox3_CheckedChanged(sender As Object, e As EventArgs) Handles CheckBox3.CheckedChanged If CheckBox3.Checked = True Then TextBox7.Text += fntext & vbCrLf End If End Sub Private Sub CheckBox4_CheckedChanged(sender As Object, e As EventArgs) Handles CheckBox4.CheckedChanged If CheckBox4.Checked = True Then TextBox7.Text += artext & vbCrLf End If End …

I would do the following: Private Sub TextBox3_TextChanged(sender As Object, e As EventArgs) Handles TextBox3.TextChanged Dim items = (From it In ListBox1.Items Select it Where it.ToString().IndexOf(TextBox3.Text, StringComparison.CurrentCultureIgnoreCase) >= 0).ToArray ListBox1.BeginUpdate() ListBox1.Items.Clear() For Each item As Object In items ListBox1.Items.Add(item) Next If String.IsNullOrEmpty(TextBox3.Text) Then ListBox1.Items.AddRange(My.Settings.userlist.ToString) End If ListBox1.EndUpdate() End Sub

Probably the code is missing the following `Imports`: Imports Microsoft.VisualBasic.DateAndTime

@rajeshmca03 Do you mean a Global Unique Identifier? If so, you may get a new Guid and just append a counter, for example like this: Module Module1 Sub Main() Try Dim sGuid As String = String.Empty Dim nOption As Int32 = 0 Dim sequenceCount As Int32 = 0 Dim curGlobalIdent …

Hello. The most easiest way I see to do what you ask is the following: Dim Search1, Search2, Search3, Search4, Search5, Search6, Search7 As String Dim s As String = tbxCustomerName.Text Dim words As String() = Split(s, " ") For i as Int32 = 0 To words.Length - 1 Select …

I found the following in your code: 1) There is missing a `Exit Sub` right after `Messagebox` in between lines 30 and 31. 2) Line 46 where variable `i` is incremented, should go before `Loop` in line 45. 3) In line 36 you are comparing `strProductos(i)` (which is a `String`) …

"Windows PowerShell is a programming language from Microsoft that is primarily designed for system administration. Since PowerShell is built on top of the .NET framework, .NET’s excellent regular expression support is also available to PowerShell programmers."

Be sure to have all the tags 'closed' (e.g. `<asp:Panel ... />` or `<asp:Panel .... > ....</asp:Panel>`) and all enclosed inside `<form>...</form>`.

Of course I suppose the student data has been entered correctly, but I can't see the need for entering a third field: status. If you want to assure the password you may constrain passwords to those containing both capital and lower letters and special characters like !,$,%, and so on. …

You must add a condition because the columns are being added twice: in design-time and in run time. (DesignMode property from Windows Forms components not 100% reliable, so use this other): Public Sub New() Width = 500 Height = 200 If System.ComponentModel.LicenseManager.UsageMode = System.ComponentModel.LicenseUsageMode.Designtime Then Dim Col1 = New DataGridViewTextBoxColumn …

You may want to add a user control, with 4 or 6 textboxes depending on IPv4 or IPv6. For example: Public Class IP_Textbox Const nBytes As Int32 = 4 ' IPv4 (change to =6 if IPv6) Dim vTextbox(nBytes - 1) As TextBox Dim vLabel(nBytes - 2) As Label Private Sub …

I haven't tried your code, but instead of using `wsSource.Cells(Rows.Count, 1).End(xlUp).Row`, you could use `.UsedRange`. UsedRange knows really where the data ends.
