I am trying to restrict user to select value between a limit using SpinButton in VBA but its not working for me
Here is what I have tried
Private Sub UserForm_Initialize()
decimalSpin_Button.Min = 0
decimalSpin_Button.Max = 5
End Sub
Private Sub decimalSpin_Button_Change()
decimalPlaces_Value.Text = decimalSpin_Button.Value
End Sub
Private Sub decimalSpin_Button_SpinDown()
decimalPlaces_Value.Text = decimalPlaces_Value.Text - 1
End Sub
Private Sub decimalSpin_Button_SpinUp()
decimalPlaces_Value.Text = val(decimalPlaces_Value.Text) + 1
End Sub
You don't need the _SpinDown() and _SpinUp() This will do what you want
Private Sub UserForm_Initialize()
decimalSpin_Button.Min = 0
decimalSpin_Button.Max = 5
End Sub
Private Sub decimalSpin_Button_Change()
decimalPlaces_Value.Text = decimalSpin_Button.Value
End Sub

i have in a windows.form a combobox and a datagridview,
i add rows in datagridview with a button and get the value(string) from combobox and if i double click on the row of datagridview i delete the row.
When i add the row i want to hide/disable/remove the combobox value and when i delete the row i want to restore it in combobox.
The combobox values are binding from dataset source and combobox is dropdownlist style.
I try some things until now but this is what i think is better approach and where i am:
Dim filterList As List(Of String) = New List(Of String)
Private Sub filterListAdd()
Dim dgResult As String
filterList .Clear() 'Clear the list so no duplicates
For i As Integer = 0 To combobox.Items.Count - 1
Dim a As String = combobox.GetItemText(combobox.Items(i))
For row As Integer = 0 To Dgview.RowCount - 1
For col As Integer = 0 To Dgview.ColumnCount - 1
Next
Surname = Dgview.Rows(row).Cells(0).Value.ToString
If dgResult = a Then
filterList .Add(a) 'Add to list
End If
Next
Next i
End Sub
Private Sub Button_Click(sender As Object, e As EventArgs) Handles Button.Click
Dgview.Rows.Add(combobox.Text)
filterListAdd()
'Here i want to bindingsource.filter = filterList
End Sub
Private Sub Dgview_MouseDoubleClick(sender As Object, e As MouseEventArgs) Handles Dgview.MouseDoubleClick
Dgview.Rows.Remove(Dgview.CurrentRow)
'I Guess here with the same way i filter it again
End Sub
Any help will be appreciated, thanks in advance.

In that form i don't update the dataset because every change i want to make it in other form, so when i finish from here the dataset.table has no changes.
With the following code I fill a Treeview with a root node and several child nodes in the MainForm LoadEvent. With the button btnPing I go through the nodes and search for child nodes with level 2. These nodes are then queried with My.computer.network.ping and the ForeColor of the ChildNode is colored according to the result red or green. The whole works synonymous. However, the GUI freezes me every time.
'### TreeView Test

Now I would like to convert the whole so that the Ping runs in a separate thread. Now I have only one understanding question about the process. Can I start a thread with parameter transfer? Then I would run through the list and start with each node with level 2 a thread and wait for feedback. How would the best approach be?
Best Regards
Kay
Here's another approach:
Sub BtnPingClick(sender As Object, e As EventArgs)
'Treeview rekursiv durchsuchen
RecurseNodes(TreeView1.Nodes)
End Sub
Private Async Sub RecurseNodes(ByVal col As TreeNodeCollection)
For Each tn As TreeNode In col
If tn.Level = 2 Then
Dim T As Task(Of Boolean) = Ping(tn.Text)
Await T
tn.ForeColor = If(T.Result, Color.Green, Color.Red)
tn.StateImageIndex = If(T.Result, 4, 5)
ElseIf tn.Nodes.Count > 0 Then
RecurseNodes(tn.Nodes)
End If
Next tn
End Sub
Private Function Ping(ByVal ip As String) As Task(Of Boolean)
Return Task.Factory.StartNew(Of Boolean)(
Function() As Boolean
Try
Return My.Computer.Network.Ping(ip)
Catch ex As Exception
Return False
End Try
End Function)
End Function
Some ideas...
Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click
Dim t As Task = Task.Run(Sub()
RecurseNodes(TreeView1.Nodes(0))
End Sub)
End Sub
Private Sub RecurseNodes(ByVal col As TreeNode)
For Each tn As TreeNode In col.Nodes
If tn.Level < 2 AndAlso tn.Nodes.Count > 0 Then
RecurseNodes(tn)
ElseIf tn.Level = 2 Then
Dim tp As Task
tp = Task.Run(Sub()
Dim c As Color
Dim idx As Integer
Try
If My.Computer.Network.Ping(tn.Text) Then
c = Color.Green
idx = 4
Else
c = Color.Red
idx = 5
End If
Catch ex As Exception

i have a simple userform with a textbox where the user inserts a date and another textbox where the user inserts a number. When i try to use the data from the form it will not show the inserted data: the date shows as 12:00:00 am and the numeber shows as 0 .
Here is the userform
Public Sub CancelButton_Click()
Unload Me
End
End Sub
Public Sub UserForm_Initialize()
TextBox1.Value = ""
TextBox2.Value = ""
End Sub
Public Sub btnOK_Click()
Dim xSO As Date
Dim ySO As String
xSO = Format(TimeValue(TextBox1.Value), "dd.mm.yyyy")
ySO = TextBox2.Value
Unload Me
End Sub
Here is the minimum sub:
Public xSO As Long, ySO As Long
Sub ffffff()
Dim x As Date, y As String
UserForm19.Show
x = xSO 'Format(TextBox1.Value, "dd.mm.yyyy")
y = ySO 'UserForm19.TextBox2.text
MsgBox x
MsgBox y
End Sub
You declared xSO and ySO twice.
Remove the local declaration from Public Sub btnOK_Click()
Dim xSO As Date
Dim ySO As String
I have a function that needs to execute every 30 mins. How can I filter it using Today.Minute?
Here are the Codes I made.

Dim Counting As Integer = 0
Try
While (Not stopping)
While Counting <> 2
If Today.Minute >= 0 Then
If Counting = 1 Then
ElseIf Counting = 0 Or Counting = 2 Then
PingServers()
Counting = Counting + 1
ElseIf Today.Minute >= 31 Then
If Counting = 1 Then
PingServers()
Counting = Counting + 1
ElseIf Counting = 0 Then
End If
End If
End While
If Counting = 2 Then
DoFunction()
End If
End While
Catch ex As Exception

Please any one. Help :3
I guess something like this would do the trick:
Module StartupModule
Private _timer As Timers.Timer
Sub Main()
SetTimer(3000)
Console.ReadLine()
KillTimer()
End Sub
Private Sub SetTimer(interval As Double)
_timer = New Timers.Timer(interval)
AddHandler _timer.Elapsed, AddressOf OnTimedEvent
_timer.Start()
End Sub
Private Sub KillTimer()
_timer.Stop()
_timer.Dispose()
End Sub
Private Sub OnTimedEvent(source As Object, e As ElapsedEventArgs)
Console.WriteLine(DateTime.Now)
End Sub
End Module
i created this sub
Sub CreateNewNode(tree As TreeView, e As NodeLabelEditEventArgs)
Dim nodeTxt As String
nodeTxt = e.Label
If e.Node.Level = 0 Then
Dim obj_carsType As New Cls_carsType
Dim Entity As New tblcarsType
Entity.Type = nodeTxt
obj_carsType .Insert(Entity)
Dim q = (From i In obj_logsType.Fill Select i.ID).Last
e.CancelEdit = True
tree.Nodes.Remove(e.Node)
tree.Nodes.Add(nodeTxt & " : " & q.tostring)
end sub
Sub TreeView1_NodeMouseClick()
e.Node.ContextMenuStrip =ContextMenuStrip1
end sub
Private Sub NEWITEmToolStripMenuItem_Click()
end sub
in last sub need to call first sub. also in last sub if user click on NEWITEM i must call the first sub how can i do it?? please help me
I think you need something like this:
Private Sub NEWITEmToolStripMenuItem_Click(byval sender as object, byval e as eventargs)
CreateNewNode(ctype(sender, TreeView), ctype(e,NodeLabelEditEventArgs))
end sub
