"If I click the answer(ie) radio button, it should check the database for answer and if the answer is correct it should add the mark to a separate variable". This is my problem in my project.
Marks are stored along in the question table.
question table contians the fields such as Qno, Question, Ans1,Ans2,Ans3, Ans4, CorrectAnswer,Mark.

The users marks should not go into the questions table. They should go into a table that lists the users ID, the question ID, and the users mark for that question. The correct answer should be obtained from the question table. You can update this table when the user clicks on an answer on the form.
After that it's a simply matter of retrieving the correct mark from the question and the users mark from this new table.

My next problem, I had created the radiobutton only at the runtime of the form. All radio button for all questions are added on a panel at each and every qestions. There is no common name or id for radiobuttons. How can i get the value of checked radiobutton.

You create them and wire them up the same way the designer generated code does.
Dim newRadioButton As New RadioButton
With newRadioButton
.Location = blah
.Text = blah
blah
blah
End With
Panel1.Controls.Add(newRadioBUtton)

Creating radiobutton is not my problem? Only getting the value of all runtime radiobuttons at the single button click is my problem. see the following code:
Public Function Createcontrols(ByVal intidx As Integer)
radio1 = New RadioButton()
radio2 = New RadioButton()
radio1.Top = r1
radio1.Left = x
radio1.Height = 25
radio1.Width = 150
radio1.Text = ans1
Me.Controls.Add(radio1)
radio2.Top = r1
radio2.Left = r2
radio2.Height = 25
radio2.Width = 150
radio2.Text = ans2
Me.Controls.Add(radio2)
Panel1.Height = 25
Panel1.Width = 850
Panel1.Left = x
Panel1.Top = p1
Me.Controls.Add(Panel1)
Panel1.Controls.Add(radio1)
Panel1.Controls.Add(radio2)
end function
For intIdx = 0 To 4
Createcontrols(intIdx)
Next
by the above code i can get 5 radio1 and 5 radio2 on 5 panel control.
It is perfectly working.
But the problem is if I check any one radio button on all panel controls at a time (ie)keeping all 5 radio button's checked = true and then click submit button to get all checked radio button values.(ie) I have to print all checked radio buttons text in the msgbox.How can i print?

Well, you're defining a Function but not returning a value. Make this a Sub.
Next, inside this code, assign a Name to each of the radio buttons
radio1.Name = "Radio1"
or whatever name you want to use.
All you have to do is enumerate the controls on the panel:
Public Function GetRadioButtonChecked(ByVal controlName As String) As Boolean
For Each c As Control In Panel1.Controls
If TypeOf c Is RadioButton Then
Dim rb As RadioButton = DirectCast(c, RadioButton)
If rb.Name = controlName Then
Return rb.Checked
End If
End If
Next
Return False
End Function

Don't tell me you're automating Word from inside a Web Forms (ASP.NET) application?? This is a very bad idea because Word is a heavy weight object that takes forever to contruct and shutdown. It also takes a ton of memory and will just bog your application down, without even doing anything with it!
If you have Word documents, convert them to HTML format ahead of time, not when the page is requesting them.

Im having a problem with two different controls in VB.Net; the reportViewer and the webBrowser control. Everything seems to work fine until you come to print something, the first time I click the print button, or call the print method, nothing happens, the second time and thereafter everything works just fine. Has anyone else had a similar problem? or does anyone know to a solution? I've tried calling the print method twice with the webBrowser and even that doesn't work, I've also tried compiling it for release instead of debug.

I've never heard of the problem, not can I find any reference to it. What does you're printing code look like? I'm more than willing to bet the bug is with your code and not with the .NET Framework.
|
|
|
|
|
Well there is no code for the reportViewer its an embeded button in the control. and the printing code for the webBrowser is just a call to the ".print" method which takes no parameters.

I did finally find a blurb about the problem. Read[^] and Read[^].

cheers, I like microsoft's work around "To work around this problem, click Print again." classic!

A hotfix was released back in 2006. It's possible that it made it's way into SP1 for Visual Studio .NET 2005, though I can't confirm it.

Alegedly it has, unfortunatly, it doesnt solve the problem with the webBrowser control, I was hoping they were related, but it doesn't seem so

Hi, I just beginning programming in vb.net 2005. I found three control that I couldn't understand on how to use it. These control are Panel control, FlowLayoutPanel control and TableLayoutPanel control. I used to see groupbox and tab control but I understand about this control and know the logic how to use it.
But for these 3 controls above, i do not know where in what kind of situation that developer use these control?

1)The Panel acts as a container, similar to the groupbox, that you can use to move many controls at once or to group controls such as radiobuttons. The benefit of the panel is that you can hide the borders and set it's backcolor to transperent,so it is invisible which you can't do with GroupBox.
2) The Flowlayout panel acts in a way to dynamically order controls. Say you create a flow layout panel and add five buttons to it, you can tell it how to make it flow, whether they stack on each other vertically, Horizantally etc.
3) The Table Layout Panel allows you to define your form into sections, you can add rows and columns, and customize their sizes, in such a way as to seperate different parts of your form, or alter the layout.

Thank you very much for your explaination.

The first point i just understand because i also used to face a problem when I want to group a control and do not want the user to see the border of the group control.
But for the second and third explianation, I still don't understand. The point that I don't understand is in what circumstance during software development that we use FlowLayou Panel and TableLayoutPanel? For example: We use checkbox to let user choose more than one answer, or we use radio button in the circumstance that we want to give an opportunity to the user to choose only one choice.
Finally, thank you for your detail explaination

TableLayout : It's similar to using a table in word or html where the table simply defines the region for the content, in this case, the content is whatever controls you add. Another benefit is that using percentages in sizing, it will resize in proportion, which is good for making programs to cater for different resolutions.
FlowLayoutPanel is one of those things you sort of have to try out for yourself to get a feel for it, it's great when adding controls to the form by code and it lays it out automatically.
For more info on Flow layout panel check out this:

That's it. This real example that made me understand the reason that we use TableLayoutPanel and FlowLayoutPanel.

Am new to VB.net, i have been reading my books very well and i swa a big difference between VB6 and .Net, i learned about ADO.net, Adapters and Datasets, and binding of Control, have Successfully done Database Application in.Net, taking Example from my Books. at my work place they use Visual Studio.Net a French version. am English, but know my way around. i have Completed my Connection to My MSSQl database and generate the dataset from Adapter as the Steps that am supposed to do. i Wrote my Code, but when i run my Program it Gives me the Following Error
"SinglePropertyApplication.exe!SinglePropertyApplication.frmSingle.frmsingle_Load(Object sender = {SinglePropertyApplication.frmSingle}, System.EventArgs e = {System.EventArgs}) Ligne 824 + 0x24 octets Basic"
"SinglePropertyApplication.exe!SinglePropertyApplication.frmSingle.Main() Ligne 3 + 0x1d octets Basic"
"Une Exception non geree du type'System.data.sqlClient.SqlException s'est produite dans system.data.dll"
i used google language tools to convert the language, but all this did not make sense.
secondly the name of my Table is Property, hence Property is a keywork in vb the system Allowed me to write it this way where am not able to but "".
and my Error point s to this line in the Form load
Private Sub frmsingle_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load<br />
<br />
Locktextboxes()'this one is Good<br />
<br />
SqlDataAdapter1.Fill(DsProperty112) 'this is the green highlighted problem<br />
<br />
End Sub<br />
like this follwoing code as i said my table is Property, here i had to put it under double qutes""
Dim intCurrentRecordNumber As Integer = Me.BindingContext(DsProperty112, "property").Position
but in this Code
Dim newRow As DataRow = DsProperty112._PROPERTY.New_PROPERTYRow
i had to Put an Underscore.
tell me is it right?, because when i use the name Property without an underscore it gives me a Problem.

Then you can NOT use any of the classes that start with "Sql" in the names. IMport the SqlClient namespace will also not do you any good. There are reserved for use with Microsoft's SQL Server and will not work with Access databases.
For Access, you have to use the classes that start with "OleDb", like OleDbConnection, OleDbCommand, ...

Dave is correct. because your code read the sql word. Try to declare what i post last time. try to see if the error will be change. if the error change post the error again here.
