Hi everyone,
Does anyone have any idea how to do the following code snippet i posted below in web method?
protected void Page_Load(object sender, EventArgs e)
{
// Get the hostname
string myHost = System.Net.Dns.GetHostName();
// Get the IP from the host name
//string myIP = System.Net.Dns.GetHostEntry(myHost).AddressList[0].ToString();
string connect = "PROVIDER=Microsoft.Jet.OLEDB.4.0;DATA Source=C:\\inetpub\\wwwroot\\Request\\App_Data\\TV.mdb";
string query = "SELECT COUNT(IPAddress) FROM Request WHERE IPAddress = ?";
int result = 0;
using (OleDbConnection conn = new OleDbConnection(connect))
{
using (OleDbCommand cmd = new OleDbCommand(query, conn))
{
cmd.CommandType = CommandType.Text;
cmd.Parameters.AddWithValue("IPAddress", myHost);
conn.Open();
result = (int)cmd.ExecuteScalar();
}
}
if (result <= 0)
{
Response.Redirect("Unautorized.aspx");
}
thanks.

Do you mean using a method decorated with the WebMethod attribute and called from JavaScript?

Ya, something like that. But i need to use C# instead of Javascript. Can you show me some examples on it?
thanks.

This make no sence. If you are using C# then call the method like any other method.

Hi
I have one MDI(NewRoot) form and 2 child forms(StartUpForm ,StartUpForm1 ), in MDI formload i have assigned MDI using below code.
StartUpForm suf = new StartUpForm();
suf.MdiParent = this;
in StartUpForm i want to open StartUpForm1 with same mdi(NewRoot) so in StartUpForm's button click i have used below code
StartUpForm1 suf1 = new StartUpForm1(); suf1.Show();
Even though the form is opening but it is opening as seperate form.I want to open it as single window/form.
Thnaks & Regards
Pawan

If you're doing it in suf then you can assign it's MdiParent as the parent of the other form (you will have to do this after the constructor)
StartUpForm1 suf1 = new StartUpForm1();
suf1.MdiParent = this.MdiParent;

Hi,
I'm working on a project where I have to parse HTML pages in a C# Forms application. Parsing HTML is actually quite easy, espetially with mshtml. I just use the built in web browser and get all the information I need from the HTMLDocument and IHTMLDocument2.
I wanted to go a step further and also parse the javascript code, that is included in the web page. For now I am just able to get the tag and the included javascript code as a string.
Because javascript is one of the most widely spread script langues on the web, I assumed it would be as easy to parse as HTML. But I didn't find anything that would support my theory.
I just can't believe thet java script managing is not included in C#, but still, maybe I wasn't searching for an answer hard enough...
Does anyone know, if there is an easier way to parse javascript code than to write my own parser?
and sory for my bad english, i'm not a native speaker.

Unnecessary, all you need is to get the WebResponse from a WebRequest.
What are you trying to accomplish with the JavaScript?

Could you explain this? I don't see a way to get the parsed HTML directly from a WebResponse
|

Parsing the HTML by hand, ok, but surely that wouldn't be the best way all the time (maybe he needs a complete DOM tree? to me that seems likely, seeing as he even wants to parse the javascript)
edit: I wrote this post before reading his second post

Thats exactly what I would like  .
As I said, geting the complete HTML DOM tree is not that hard.
But the script part is shown as one element. Maybe I overlooked something, but for now it seems that the script part is only accessible as the inner HTML of the element.
Thats my question. Is it possible to access and identify the elements inside the javascript part otherwise than to parse it as a raw string?

AFAIK there is no method to parse the javascript other than to process the string. Using a Regular Expression this shouldn't be that difficult and I would agrue easier with the string returned by WebRequest rather than walking the DOM in an HTMLDocument

Not that I know of. Microsoft provides a scripting library that can parse and execute JavaScript, but as far as I've been able to find out it doesn't let you have the AST (or something similar).

There is no such DOM for JavaScript as there is for HTML. HTML is easy. It kind of resembles XML, with a tree of markup tags. Java has no such easy structure. It's more like C# and VB.NET. There are object models for those, Visual Studio uses them. But, Visual Studio does not have a DOM for JavaScript, nor does the .NET Framework.
The closest you may get is to research Sun's options and see if they have an equiv' DOM that you can use. Don't get your hopes up though...

WebResponse gives you the complete DOM tree. What more do you want?

You're correct, it does not create a DOM tree as far as objects like a HTMLDocument, it's not intended to do so, however; the stream contains all elements of the DOM which can be loaded into a XDocument, or XMLDocument, and parsed in that manner, which IMO, is a better approach for the OP

Does that really work? Last time I checked, HTML made XmlDocument very angry, and it refused to parse it.
|
|

I stand corrected. It's been a while since I tried it last. Thought XDocument was more forgiving.

Since my test application is a simple web browser its easier to just get the formatted source code from the HTMLDocument that is included in the web browser anyway (at least I think it is).
On the side I wanted to show the document structure and since its already served on a silver plate, building a html element tree and showing it within an TreeView was simple.
I hoped to find a similar way for showing the structure of the included javascript source code (this time I don't have in mind any kind of a tree, but just the function names maybe also variable names,...).
I don't mind to write my own parser, but if there is a better solution, why re-invent the wheel
