So what exactly is the question?, and how does it relate to SQL Server?
There are already forum software packages written that you can either purchase, or are open source. You just have to find one that you like, download it, and load it in Visual Studio.

main motive is that i am creating an project on educational website in which a student logins and post his query related to his subject and that query should be saved in sql database. when the faculty of that particular subject logins, he should view the query section for the queries submitted by student and answer them. then again when student logins and visits the query section and he sees the answer replied by faculty. its should be just same as the forum section of this website.

I think in the future, perhaps just say the student logs in to ask a question, and the teacher logs in the provide the answer, then the student logs in to read the correct answer.
I would of quickly understood that.
Now that we have your intentions out of the way,
You should start with a designer, to help design how you want your forms to look and feel, then create a chart, order of operation, page flow chart, and then start writing code for it.
Lock down the user interface first, then start writing code for the mechanics of it like the database reads and writes. Login and security and so forth.
A snippet of code will not create your project.
There must be somebody at your office that has the complete vision.

For this you need to workout with both Front End (ASP.Net) as well as Back End (SQL).
Create two database tables one as UserMaster for Login User Details and other for Posts(Messages) as PostMaster having column for Posts, DateofPost, Status, PostedBy etc...
and when u click and save any new Post send the Login UserCode with query and save it in column PostedBy inPostMaster table and second thing is when any one logins to the Application check at login if the user is Admin or just normal user,,if it is Normal User then pick the data from PostMaster where PostedBy = LoginUser Code else in case if it is Admin then pick all data accordingly.
This is just the logic I give you..workaround with this..if stuck somewhere will discuss in next post from you.

Hello,
There is a website that has some input boxes and after you enter the input you press a button and an answer shows up.
1) I am pretty sure that the website is in ASP, how can I be sure?
2) I want to make a windows application that behaves like the website, for the user it will have a specific MMI and to the internet it shell behave like I am working in the browser.
can anyone please give me a starting point?
Thanks

Look at the URL of that website: does it end with ".asp" or ".aspx"? Then it is an asp application. What you describe could also be achieved with JavaScript in an otherwise static html page, and of course you could do it also with php, cgi scripting, and other methods.

this is my code
<asp:Label ID="Label7" runat="server" BorderStyle="None" Width="80px" Text="Thumb URL" />
<asp:FileUpload ID="FileUpload1" runat="server" Width="200px" Filebytes='<%# Bind("thumbnail") %>' />
<asp:RequiredFieldValidator ID="RequiredFieldValidator7" runat="server" Display="Dynamic" ControlToValidate="FileUpload1" ErrorMessage="Required" /><br />
<asp:Label ID="Label8" runat="server" BorderStyle="None" Width="80px" Text="Image URL" />
<asp:FileUpload ID="FileUpload2" runat="server" Width="200px" Filebytes='<%# Bind("image") %>' /> /><br />
<asp:RequiredFieldValidator ID="RequiredFieldValidator8" runat="server" Display="Dynamic" ControlToValidate="FileUpload2" ErrorMessage="Required" /><br /><br />
<asp:LinkButton ID="LinkButton1" runat="server" CommandName="Update" Text="Update" />
<asp:LinkButton ID="LinkButton2" runat="server" CommandName="Cancel" Text="Cancel" CausesValidation="false" />
</EditItemTemplate>

I don't think that is legal with the Bind, I haven't used the FileUpload webform object in years, just from Code, FileBytes is a code property to get the total size of the upload on the server side.
<asp:FileUpload ID="FileUpload1" runat="server" Width="200px" Filebytes='<%# Bind("thumbnail") %>' />
<asp:FileUpload ID="FileUpload1" runat="server" Width="200px" />

Try removing the snippet Filebytes='<%# Bind("thumbnail") %>' from .aspx page and put it at .aspx.cs file where you are checking for the File Upload control has file or not..!

That's not going to work, Filebytes get the file uploaded as a stream or array of bytes, so you can write it as a blob, or do a direct write to the disk drive, or pass the stream to another server.
Gets an array of the bytes in a file that is specified by using a FileUpload control.
It's the other way around
Dim Input(fileLen - 1) As Byte
Input = FileUpload1.FileBytes

Hi,
I have listbox wich is dynamically updated with an AJAX call the declaration of the controls
<asp:DropDownList ID="lb_Retour" name="drp_Retour" runat="server">
</asp:DropDownList>
<asp:ListBox SelectionMode="Multiple" Height="160px" Width="300px" ID="lb_Info"
runat="server"></asp:ListBox>
In code behind i'm binding dropdownlist to datasource and adding OnChange Event to make an AJAX call with the function getvalues
protected void Page_Load(object sender, EventArgs e)
{
lb_Retour.DataSource = Ctx.Retours.OrderBy(n => n.Id).Select(n => n);
lb_Retour.DataTextField = "Retour";
lb_Retour.DataValueField = "Id";
lb_Retour.DataBind();
lb_Retour.Items.Insert(0, new ListItem("-Selectionner-", "0"));
lb_Retour.Attributes["onchange"] = "getValues(this);";
}
The javascript wich update the listbox values depending on dropdowlist selection
<script type="text/javascript">
function getValues(Control) {
var Code = Control.value;
if (Control.value.trim() != "")
$.ajax({
type: "POST",
url: "../Services/DomaineService.asmx/GetResponse",
data: "{ 'typeId': '" + Code + "'}",
contentType: "application/json; charset=utf-8",
dataType: "json",
success: OnSuccess,
error: OnError
});
}
function OnSuccess(data, status) {
$('#ctl00_ContentPlaceHolder1_lb_Info').children().remove();
$('#ctl00_ContentPlaceHolder1_lb_Info').append(data.d.ValueList);
}
function OnError(request, status, error) {
alert(error.toString());
}
<script>
The data that returns the webservice is
<option value="1">toto</option><option value="2">titi</option><option value="3">tata</option>
below the Webservice Code
[WebMethod]
public ResponseInfo GetResponse(string typeId)
{
ResponseInfo xResponse = new ResponseInfo();
xResponse.ValueList ="";
PDataContext Ctx = new PDataContext();
var query = (from objInfo in Ctx.Infos
where objInfo.Type == Convert.ToInt32(typeId)
select objInfo
);
foreach (InfoComplementaire item in query.ToList())
{
xResponse.ValueList +="<option value=\""+item.Id.ToString()+"\">"+item.InfoComplementaire1.ToString()+"</option>";
}
return xResponse;
}
Well everthing is ok the values are update depending on selected on the dropdownlist the probem is when i try to select item in the list box in code behind i get nothing at all item.Selected is always false when the option values comes from the AJAX call!!
Thank you for help

That would be onClientClick to run javasccript before the page submits a postback

That's because you didn't include the selected attribute in the option tag when you wrote the new value in javascript.
Also, according to .net law, you can't populate a listbox or dropdown box in code behind, or from the server, and delete the values with javascript, and send the new selected value back to the server on postback, because the server has a temp list of the values it sent to the browser the first time, and it won't match the list on the postback.
You'll get nothing selected, because the original values are gone.
If your going to use javascript to populate the values via web service, you have to use an empty box, populate it, get the selection, send it back via web service,

Try by putting AutoPostBack property of DropDownlist set to "True"

I almost said that as well,
but you can't autopostback to the server if you use javascript / JQuery to wipe out the original list and create a new list from a web service, because the server retains the values it sent the first time, and expects one of those values to be selected.
If the value is not present, it will trigger a tamper or fraud error.

First of all I would say don't do this. You should be using CSS rather than hard coding style in your code. You can change the image by applying different classes to the element on the client. You can also make use to CSS media type, @print, to control how the page is rendered when printing.
Failure is not an option; it's the default selection.

Hi,
We have to select the image depending upon query string, is it possible. Now I found that the image is not set even for the page itself. First it needs to be set for the page then it should print on the printer.
And then it should come in the render to pdf.
Any help please, thanks in advance, its little bit urgent please. Any link or any code snippet helps a lot. In the mean time I will be googling.
Thanks & Regards,

If you aren't seeing the image, then chances are that your path is wrong. Don't rely on relative pathing such as ../ to get to a resource. Always go from a known root to the resource - that way, you can assure yourself that you get to the resource from whereever you are in the site.

Yes, thanks fixed

You should research themes. Now, if the images changes or the path to it needs updated you need to fix the code, recompile, deploy and recycle the worker process, rather than update a CSS file.

So how is your poor design and understanding reason for me, or anyone, to rush a response to you?
Failure is not an option; it's the default selection.
