I have two labels on my form
Label1
Label2
In the form load I generate a radiobutton for each label, with the text property being the name of the label.So two radiobuttons are made The first one will have text: Label1 I have
Quote:
dim objStore as object
Example:I select the first radiobutton (text: Label1)Then Label1 should be stored in objStore as object.So then I can do
objStore.text = "test"
I have say 4 asp.net radiobuttons which are grouped, I want to find out which one is checked.
What seems natural to do is:
Select Case RadioButton.Checked = True
Case myRadioButton1
Case myRadioButton2
Case myRadioButton3
Case Else
End Select
I just get a 'reference to a non-shared member reference' error. It's a shame because it seems such a clean way to do this test.. Is it possible??
I need to avoid that any of a set of radiobutton autoselects at form load. Is possible?
View 5 RepliesCan't seem to find code for radiobutton to hilight multiple choices from listbox, e.g.
If radiobutton1.clicked = true then
listbox1.selecteditems = "apple" "cherry" "pear
if radiobutton2.clicked = true
listbox1selecteditems = "apple" "cherry" etc....
The code below obviously works, but there must be a more elegant For Next code? I have 20 Radiobuttons and the user fills a textbox. I can't work out how to rename Button1 to Button2 in a loop.

Is there a way to validate a groupbox with a couple radiobuttons in it to make sure that one of the radiobuttons is selected?
Heres why I need this. I need a user to be able to select their class rank out by way of radiobuttons in a groupbox. When they click submit, I need to validate that atleast one of the radiobuttons got selected and if not display a messagebox.
I got one reply early of:
If myGroupBox.Controls.OfType(Of RadioButton).Count(Function(rb) rb.Checked) = 0 Then
'There is no RadioButton checked in myGroupBox.
End If
Is there any other ways other then that? Preferrably a more 'dumbed' down way? This is for just an entry level VB class, I would prefer not to use something of that nature if there is another way.
Im basicly making a "Settings" form and I want it to be able to check more then one radio button, but only 1 per "line" (One Per Setting)
View 4 RepliesI'm wondering if there's an easier way to do what I'm trying to do, because right now it seems like I have to program all the functionality manually.Here's my situation.

View 9 Repliesi have a form with a bunch of textbox's that are connected to a ms access data source, so i can update, edit and delete records.I also have 4 radio buttons.What i'm trying to acheive is that when a row is selected in the datagridview, the textboxes show the values in them (id, name, number, etc.),which works perfectly, and the radio buttons should show the value of the "grade" column of the cell that is selected.
So basicaly when you click a record, if the grade is 5 i want the radiobutton5 to be selected. And if i click radiobutton6 it should update the field to 6.

I wonder how to make the Radiobutton ON when webbrowser is fully loaded, and the Radiobutton OFF when the page is loading. It's like boolen. Im using Webbrowser1.If you do not understand im mean this:
1. Click on a link on a site.
2. The Radiobutton gone OFF.
3. When the page is 100% loaded, the Radiobutton gone ON.
in load of my form, i create automaticly some radiobutton in relationship with the number of Categorie in my BD i hope that when i check for exemple the radiobutton1, it show me (" hello all ")
in reality i don't want to show that, but it just for to simplify my question
this is my code for creation of radiobutton : Private Sub Gh_Produit1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load

View 1 RepliesI can't quite figure out why this Linq Statement isn't working as i would expect:
[Code]....
I would assume that this would create a new collection of anonymous types, that would be distinct. Instead it creates a collection the size of the "ThisParentCollection" with duplicate "MyAnonymousType" in it (duplicate id's).
So say I have a collection of Bloops
Class Bloop
Public FirstName
Public LastName
[Code]....
Is it possible using Linq to select the FirstName and LastName out of all the Bloops in the collection of Bloops and return a collection of Razzies? Or am i limited to a For-Loop to do my work?
To clear up any confusion, either VB or C# will do. Also this will probably lead to me asking the question of (What about using a "Where" clause).
What I have is 4 datagridviews named dgv1, dgv2 etc.I also have a variable curr_player whose value is between 1 and 4. I would like to be able to enable one of the dgvs based on the value of the curr_player variable. I'm reluctant to to write select case for each time I want to do this so the question is can I enable one of these objects based on that variable?

View 3 RepliesI was able to do this via a SELECT CASE statement, however I'm always trying to improve my code writing and was wondering if there was a better approach. Here's the scenario:Each document has x custom fields on it.There's y number of documentsHowever there's only 21 distinct custom fields, but they can obviously have n different combinations of them depending on the form.So here's what I did, I created an object called CustomFields like so:
Private Class CustomFields
Public agentaddress As String
Public agentattorney As String

I have a combo box that is populated with a list of objects (corresponding to all employee rows from a database that meet the criteria IsTech). These are not entity objects though, I have created my own class that stores the member values of each row from the DB. I have set the DisplayMemberPath to EmployeeId so the Combo box display the EmployeeId ( an integer ) member of my object. Ie. right now there are only 2 IsTech employees in my DB so the combobox displays the numbers 3 and 8 ( their EmployeeIDs).

I'm not really sure what I'm supposed to be doing with this. It's a new setting I just added and it's empty, so I'm not sure if that has anything to do with it or not. Anyone know what's going on and what needs to be done to get it to accept a value and not want to be "initialized"?
I have recently gotten my hands on a free, open-source IMAP connection API.So far, I have been successful in creating a connection to one of my accounts.Where I'm getting stuck is retrieving folders and/or emails from those folders.Does there happen to be anyone here that is familiar with this API, or even Gmail (particularly the folder structure for IMAP)?
If not, here is a link to the DLL that is listed on sourceforge and the company's website that created it (if you feel like testing):
Koolwired
Sourceforge - Koolwired API
I have created a test account so feel free to use the code below without worrying about username/password issues; I'll just delete it when I'm done with it.Here is the code I have made so far for making a connection:
Dim gSession As New Koolwired.Imap.ImapConnect("imap.gmail.com", 993, True)
Dim gAuthenticate As New Koolwired.Imap.ImapAuthenticate(gSession, "imap_test@serysoft.com", "imap_test")
Try
[code]....
When I run that code, I get an error that states:System.NullReferenceException: Object reference not sent to an instance of an object. (The bold line in the above code).
Now, I'm not sure exactly what that means. Does that mean it tried to access the server and "INBOX" doesn't exist so it gets returned a NULL value? Or is it possibly the coding itself?Maybe the Gmail folder system is weird due to the fact they use labels (even though from what I have read online, the labels act as the folders in the IMAP system).
What is the problem in below code.
d Public Sub filltextbox(ByVal dlist As String) Dim tb As TextBox = CType(Page.FindControl(dlist), TextBox) tb.Text = "hello" End Sub
Error : Object reference not set to an instance of an object.
