There is no event name "Text_Changed" under combo box of wpf.
|
|
|
|
|
Here we set the ComboBox Property
DropDownStyle=DropDownList
after setting the combobox property user only select a value from this list ,user can't write any in this combobox.
If user want to add more values in this list, user set the combobox property "Items", Here user can write our values

You might want to shorten up your name a bit. It's 3 lines long and wastes a bunch of screen real estate.

I'm developing a piece of software too (not web based). On monday I was doing some research into how to send email. First thing I thought was "I need to send email using visual basic .net". So I went to google and typed in strings such as (by 'no luck' i mean that the answer wasnt on the first page)
"send mail .net" - no luck (only comes up with asp.net solutions)
"send email visual basic" - no luck (only comes up with vb6 solutions)
"send email .net" - no luck (only comes up with asp.net solutions)
"send email .net msdn" - THE ANSWER
how hard was that?
I dont want to put you off posting questions, I've found a lot of answers here in the past, but in future use GOOGLE before you ask.
and if you're still stuck heres the page that gave me all my answers

Hi Friends,
I am using DateTimePicker in my page.
But I want that datetimepicker control should be enabled for only current month and when we select previous or next month it should be disabled.
Please help me for this.
Regards,
|
|
|
|
|
What you will need to do is to write some code within the selecteddate changed event.
you should check the datetiempicker selecteddate vs system date...do a month comparison and then set the dtp.enabled to true/false.
hope this helps
|
|
|
|
|
Try this code
Private Sub DateTimePicker1_ValueChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles DateTimePicker1.ValueChanged
If Not (DateTimePicker1.Value.Month = Now.Month AndAlso DateTimePicker1.Value.Year = Now.Year) Then
DateTimePicker1.Enabled = False
Else
DateTimePicker1.Enabled = True
End If
End Sub
|
|
|
|
|
For displaying current month in vb.net
we use Month(ToDay)
It display current month only 
|
|
|
|
|
If you're talking about the ASP.NET (Web Forms) version of the control, you can set the MinDate and MaxDate properties to limit the range the user can select from.

I have created database driven menu in which against each menu item some function name is stored. I want to call function each menu item in vb.net as this function is defined in VB.net.
Thanx

You might want to have a look in the Reflection namespace. Specifically the MethodInfo class.
|
|
|
|

You can create a database table storing something like:
menuname functionname
open openfunction
new newfunction
We can easily retrieved the function name from the database for the menu clicked.
After the function name is received by us, we have to use Reflection.
I am giving a code sample like this:
Sopposing I have a class where the functions are available
<b>Public Class Class1
Public Sub openfunction()
MsgBox("This is open function")
End Sub
End Class</b>
Then I have a button on the form, I want to call the function using reflection.
You have to import System.Reflection namespace
the code goes like this:
Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click
Dim t As Type = GetType(Class1)
Dim o As Object = Activator.CreateInstance(t)
Dim mi As MethodInfo = t.GetMethod("openfunction")
' U can write the variable which store the methor name in place of openfunction
mi.Invoke(o, Nothing)
End Sub
The code will slightly change when we will be using any reference assembly or resolving the assemblies at runtime.
Hope the solution is OK for you.

First create a function
like fun1()
use this funtion
[private\public\sub] fun1
............
....... .....
end sub

I am using BackGroundWorker to Fill my DataSets And Create DataTables and it works fine. A little marque ProgressBar shows while it's processing for around 30 or 40 seconds and then the form pops up all nicely populated.
My problem is this. I would like to go one step furthor and populate my ComboBoxs. I have about 7 or 8 ComboBoxs on my form and a couple hold quite a bit of data. (One requires over 4,000 names from a SQL database and another holds some 11,000 license plate numbers). When I try to "Add.Item" to my ComboBoxs in my thread I get a CrossThreading error. I do realize why this error occurs and I'm OK with that. The problem I'm having is coding the work-around. In this case using the InvokeRequired. Here is a brief example of what I have that is working...
Imports System.ComponentModel
Imports System.Threading
Private Handler_DoWork As DoWorkEventHandler
Private Handler_Completed As RunWorkerCompletedEventHandler
Private Sub Parking_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
AddHandler BackgroundWorker.DoWork, Handler_DoWork
AddHandler BackgroundWorker.RunWorkerCompleted, Handler_Completed
BackgroundWorker.RunWorkerAsync()
End Sub
Private Sub BackgroundWorker_DoWork(ByVal sender As Object, ByVal e As DoWorkEventArgs) Handles BackgroundWorker.DoWork
Call LoadComboBoxes()
End Sub
Private Sub LoadComboBoxes()
<<<<< Fill DataSets >>>>>>
<<<<<< Fill DataTables >>>>>>
******** I am trying to add the following ********
Dim Counter As Integer
For Counter = 0 To Me.ParkingDataSet.Officers.Rows.Count - 1
cboIssuedByKey.Items.Add(Me.ParkingDataSet.Officers.Rows(Counter)("OfficerID"))
Next
******************************************************
End Sub
I've looked at InvokeRequired and Delegate Sub and I am lost as to how to make these work. Any help on the would really help. Thank you...

I have this code which added bits to a listbox... maybe you can grab from here?
'Delegate... <br />
Delegate Sub ListBox2AddDelegate(ByVal Str As String)<br />
<br />
'Function to call...<br />
Sub ListBox2Add(ByVal Str As String)<br />
If ListBox2.InvokeRequired Then<br />
Dim d As New ListBox2AddDelegate(AddressOf ListBox2Add)<br />
Me.Invoke(d, Str)<br />
Else<br />
ListBox2.Items.Add(Str)<br />
End If<br />
End Sub
With this, I just call "Listbox2add([String to add])", and the function will decide if it needs to invoke the main thread to add the item. It may be more efficent if you added an array of strings to the combo box in one go, especially if you have thousands of items to put it.

Generate a random integer within the range of your enum then Enum.Parse the integer to the enum.

Your question is so vague, it's unanswerable. What do you mean by "manage"??
