thanks for the help @syed shanu

@ThePhantomUpvoter, can you please give me a link or something where I can learn how to dynamically create controls and add them to the toolbox? Thanks for your help

I've edited my question and given the code that is not working. But I just wanted you to know I successfully did it for a web app.

I've also changed the code i posted earlier to what I am trying to use for the desktop application. Which is not working.

True, the radio buttons are being used for multiple choice answers. But the issue is, even though i can access them by their names, anytime I move to the next question by clicking a button called "Next", the selected radio button on the previous question, is already selected on the next new question.

@Kschuler, thanx for the reply. Its true what you said.
Now, I would like to narrow it down to the issue with the radio buttons. I used the radio button-list because all the radio buttons are seen as one. I could access a radio button by index. But with what I am trying out in the desktop application, I have to code for the radio buttons differently.

Sorry, its not like i want you to do my homework for me but i've been trying some codes and ain't working and i need urgent help. The code below is one of them:

RadioButton1.InputAttributes.Add("onmouseover", _
"this.style.backgroundColor = 'red'")
RadioButton1.InputAttributes.Add("onmouseout", _
"this.style.backgroundColor = 'white'")

:)

Please Sergey, i have a very short time to work around this, learning jquery now might be good but not greatly helpful, so if you could give me a simple vb code to go about this i would be most grateful.

a code on doing both will be superb

In a way, we swayed from the actual question i asked but thanks for the help all the same, i have found a way to go about the problem i was experiencing.
The fileupload control does not show the whole file directory address, but just the filename and its extension. That is how it has been programmed for security reasons.

@richcb: can you please provide me with those codes

hahaa, sorry i forgot to tell you that i'm new to ASP.net, so don't really know what Jet can do. I only know that it's different from ACE.OLEDB

And can the lock me removed or how do i know that the thread has finished because the program halts because of the error

I am still having the same error, can you please help me out? I am using Excel 2010

Can you please give me this code in VB?

That's right. I have stored the question number, the question, the various choices/answer suggestions and the correct answer in the database.

Thank you, best answer

Like you said i was doing some bad coding, i've resolved the "no row in position" problem by substituting the for loop with a while loop and it works just perfectly. Thanks a lot

I checked as you said and it seems to be generating some random numbers more than once, could that be the problem?

Ok, I am now wondering what may be wrong with my query?

I checked the table in my database, and i used the number of rows in the table to set bounds, that's why i'm confused. Because there are enough rows.

Which i now agree, but now i'm also getting this error:
'There is no row at position 29.'
That there are no rows in some positions, which i guess the GoTo X was handling. Don't know if you can suggest a way around that as well?

In other words, any better code to replace this:
X: For i = 0 To a.GetUpperBound(0)
t = arbit.Next(1, 99)

If Array.IndexOf(a, t) = -1 Then
a(i) = t

Else
GoTo X
End If

Next
?

@ThePhantomUpvoter, thank you for your follow up, i took out the Goto X, and it was working better than before, but the only thing was that an error kept reoccurring,
'There is no row at position 38'
'There is no row at position 39'
And with the loop, i figured that if i wanted to do the query that number of times, then a loop will do

@Sergey, debugging process is slowed down, and the page doesn't load at all sometimes. The page taking to long to load doesn't make the application perform well.
@ThePhantomUpvoter, How do i make it better?

Thank you, that's why i always ask questions when i'm stuck during coding, it helps me to always solve the problem. Solved it finally. Thanks again

The exception is at the line i put the code, and the correct column holds integer values.

I already have the code below, only that i don't convert it but it works just fine
r.SelectedIndex = dt.Rows(ctr).Item("selected")

And i tried both the codes above to see if it could automatically check the right radio button by retrieving its correct value from the database but it's still giving me the same error:
"object reference not set to an instance of the object"

ok...can you please help me with those lines of codes. How do i code that?

0k,,I've improved the question. Hope it helps

Thank you Nandakishorerao, i tried your example but i gives me this error:
"Object reference not set to an instance of an object."
In my database i store the correct answer as an 'int' but not as text, so it probably check against the number of items in the radio button list, anyway on how to handle that?
Thank you again

Thanks, its working just perfectly, i needed the idea, so i could apply it to the 'explain value' i retrieve from my database. Thanks for the advice

Thank you very much vinodkumarnie for the help, i guess it would work perfectly

@Ankur\m/, yes i did

@ryanb31, i just had the idea but had no idea to go about.
@Hariharan, thanks for the idea i'll try it, it sounds good.
@aspnet_regiis -i, any suggestions or links. I need more options

Please i checked the code behind but there isn't such a line, I am even checking the events can't find at Page_Load.

Thanks du[DE], please where do i find the 'AutoPostBack' property? is it the properties of the page or button or what?

Thanks for the great help, i was able to devise another way of making the timer through the resource links you made available.
Thank You

Thanks for the help and i'm sorry for shouting and being rude

Anyway thanks for the correction. Didn't realise how loud i was, at least you heard me. :)

Sorry, i've been frustrated by the one i am working on. Just need help
Sorry

Exactly, you were right

Thanks. I've solved it
I was using the wrong textbox to send the value i wanted.

dim nums as String = Request("marks")

that's where the problem resides, i guess it not doing what i want it to do. So i changed it from that to:
num = Val(Request.QueryString("marks"))

i want to convert the string value of marks to a numeric value (integer) but it seems this is still not doing the job. Because it is the for loop that is not working, if only this would work problem would be solved

Before this was my code for Redirect:

Response.Redirect("QuickStart.aspx?marks=" & label1.text)

Currently it is:
Marks = Cint(label1.text)
Response.Redirect("QuickStart.aspx?marks=" & marks)

and the current one is giving error that, "Conversion from string "Label" to type 'Integer' is not valid."
