For anybody who is having the same problem I was having, I solved my problem by attaching an asmx page to my website and simply using a WebMethod that takes a string as an argument. All I have to do is call this method from my client windows application passing it a string of data points. My WebMethod then writes the data to a file where my webpage reads it before displaying. Very simple, but difficult to find information on how to do this. I didn't know that an asmx page could be attached to a website that is not originally a web service unitil I just plain tried it. I guess that makes it a webservice/website. I am in the early stages of learning ASP.net. I hope I am doing this in a practical way. Only time will tell.

I have to design a usercontrol in asp.net, which will display image in table.
how do i place the image in usercontrol? how will i use it in html, and display in browser?

You import it into your aspx, and use it the same as you would any server control.
You would put the images on your server, and put the path to them in your user control, in the markup.
<%@ Register TagPrefix="anyPrefix" Src="~/pathtoascx" TagName="thecontrolname" %>
Then <anyPrefix:thecontrolname runat="server" id="wahtver"/> with create the control.
This stuff is covered in any book on ASP.NET, I recommend buying one and working through it.

Hi.
I have a webservice - and I want to make sure that only MY application is using it.
Is this possible, in a secure way?
Thanks,

Thanks.
Unfortunately, those techniques rely on username and password credentials. I need to prevent my users from being able to build their own applications andthen using my web service with their username and password.

Cormac

Instead of using the username and password of the users, you can have a username hardcoded into your application. The users will not be able to get the username unless they have access to the code and even if they have access to the code, the password could be encrypted.

Thanks for your suggesstion.
However, this is not a solution; it is too easy to decompile .NET applications. Encrypting a password just introduces another problem: the encryption key and how to 'hide' that. Hardcoding is not the answer.
Unfortunately, I can't forsee any satisfactory solution.

Your other option is to see if you can get the IP address of the incoming request, and validate it. Of course, your users can decompile your code and change any checks you do, so.....

Yeah, plus my application needs to be usable from anywhere. I am implementing username/password authentication, but I'm worried my users could create their own application and utilise the web service (using their creddentials), and do some malicious things.
In all honesty it'd probably never happen - but it's discouraging not to be able to solve this problem.
|

Then you have to defend your application from dodgy input. You have to ensure that your webservice is strict on validating the inputs. That will minimise any damage that may occur if someone does find a way through the authentication process.

Other than these suggestions you can restrict accepting IP's from IIS:

Hi,
I have a gridview control on an ASP.NET page which I want to populate by binding an array of items to it. The items were all strings so it was easy to do, just have columns with bound fields and setting the DataFields to the property names like this:
<asp:GridView ID="myGridView" runat="server" AutoGenerateColumns="false" >
<Columns>
<asp:BoundField HeaderText="Product" DataField="Name" />
<asp:BoundField HeaderText="Description" DataField="Description" />
</Columns>
</asp:GridView>
I now need to add a new item and it consists of an object with a few strings as properties. I'd like to do this but I can't of course:
<asp:BoundField HeaderText="Product Code" DataField="Product.Code" />
...where the Product is the object and Code is a string member.
How can I do it? Do I need a template? If so, how?
Thanks 
|

Try this:
<asp:TemplateField HeaderText="Product Code">
<ItemTemplate>
<asp:Label ID="abc" runat="server"
Text='<%# Eval("Product.Code") %>'>
</asp:Label>
</ItemTemplate>
</asp:TemplateField>

The first time any application I write tries to consume a webservice I always encounter a substantial delay. Typically the delay is about 15-20 seconds. Any subsequent calls are very fast. It seems as if under the hood there is some sort of initialization process perhaps?
Can anyone tell me what is going on here and if there is a way to speed thus up? If it helps, I'm using C#, VS2005. I have this problem on any machine I develop on and any machine I run my compiled app on.
Thank you!

You can't use mail.yahoo.com unless you have a paid account with yahoo(The smtp host name may defer for the paid accounts). Try using the smtp host of your company, it should work.

Hello all,
I am having this problem with IIS, where nothing seems to appear as the default website, and when I click to expand the Websites folder, there is nothing under it. Could this be related to a security issue set on my computer? I do not have write access to the Inetpub folder, I only have read.
Sincerely,
The Major Rager

This question is for those familiar with the asp.net 2.0 ajax accordion which ships with the ajax control toolkit.
By default, the only way to close a content pane is to click on the header pane, activing the link within it which returns false and has an href of "".
What I need to do is to close the content pane from codebehind after performing a database update.
I know this probably has to be done by sending client script to the browser, but so far I've tried sending (clientscript.registerclientscriptblock(page.getType,newid,(function to click on the header))
and the control cannot be found at runtime to be clicked (document.getele...null or not an object). I know others will want to do this eventually, or perhaps have already found a way to, so I'll throw this out there and see if anyone can help.
Thanks in advance.

int[] newsChecked = new int[20];
for (int i = 0; i < dt_NewsClicked.Rows.Count;i++)
{
newsChecked[i] = Convert.ToInt32(dt_NewsClicked.Rows[i]["newsletter_type_id"].ToString());
}
for (int a = 0; a < w ; a++)
{
chkNews.Items[newsChecked[a]-1].Selected = true;
}

note : I use free SQLHelper Class to connect with database.
chkNews is my Checkbox group.
