Hi,
.NET 1.1 Question:
I have httpModule that implements IHttpModule in order to rewrite url´s. I need to store a value or in some way maintain a value between different http requests. I have been trying to accomplish this by implementing the IRequiresSessionState interface and with numerous event handlers. Is there anyone who know how to deal with this issue or can push me in the right direction?
Thanks in advance
Regards
/Rip

I guess session will be available in PrerequestHandlerExecute event. Have you tried there ?

Hi, thanks for your reply. I have tried that event handler. I may do something wrong in the implementation...

datalistconn is declared as global.
When postback, Excepton Occours, becase you can't open SqlConnection if it is already opend

I am trying to begin a simple web service application in ASP.NET. The app is to FlightRight, For this simple example, the service will support a single method, called FlightStatus. Clients call this method, passing it a flight number, and our service will return the expected arrival time of the flight. Simple right. not for me . Keep getting this error. Can somebobody please tell me where i am going wrong.
Code here
<WebService(Namespace="http://localhost/FlyRight/", _<br />
Description="Flight Information Service") _<br />
Public Class FlightStatus<br />
<br />
<WebMethod(Description="Submit the Flight Number _<br />
and a time will be returned.")> _<br />
Public Function ArrivalTime(ByVal FlightNum As String) As String<br />
<br />
Dim theTime As String<br />
<br />
Select Case FlightNum<br />
Case 1001<br />
theTime = "12:30 AM EST"<br />
Case 2002<br />
theTime = "4:15 PM EST"<br />
Case Else<br />
theTime = "INVALID FLIGHT NUMBER"<br />
End Select<br />
Return theTime <br />
End Function

ASP.NET is not authorized to access the requested resource. Consider granting access rights to the resource to the ASP.NET request identity. ASP.NET has a base process identity (typically {MACHINE}\ASPNET on IIS 5 or Network Service on IIS 6) that is used if the application is not impersonating. If the application is impersonating via <identity impersonate="true">, the identity will be the anonymous user (typically IUSR_MACHINENAME) or the authenticated request user.

Sounds like the user that you are impersonating, or the aspnet user does not have the appropriate privleges to run asp.net temp files.

The only way to write a useful chat program as a web app is to use AJAX. I'd say you'd be better off doing something else before you attempt this.

I need a VB script to pulling the url and put the sub domain portion in a variable.
I have the url to string function, but running into problems trying to pull out just the subdomain name. Like joe.mysite.com I only want joe, but if they don't have a subdomain then put in a default value like www.
I can't do a inStr because their are more than on ".".
Thanks

![Rose | [Rose]](https://codeproject.global.ssl.fastly.net/script/Forums/Images/rose.gif) Hello friends,
I am having some problem while accessing the required value from the datareader.
Below is the sample code that i have wriiten................
SqlConnection con=new SqlConnection("server=localhost;database=dept;uid=sa;pwd= ;");
SqlCommaned cmd=new SqlCommand();
Button1_Click(...)
{
cmd.CommandText="select fname from stu where sno=@sno";
cmd.Parameters.Add("@sno", TextBox1.Text.tostring();
cmd.connection=con;
con.open();
string str;
DataReader dr=cmd.ExecuteReader();
while(dr.Read())
{
str=dr.GetValue(0).ToString(); //Error: string str is not initialized
}
con.close();
}
But if i retrieve the value in a label then this code is working fine and i m getting the required valued in the label.
Tell me that how to resolve this problem.
I want to store the required valued directly in the local variable.
Plzzzzzzzzzzz help me

Do you not understand "string str is not initialized"
string str;<br />
string str = string.Empty;<br />
I didn't get any requirements for the signature
|
|
|
|
|
str=dr[0].ToString();
You have a Nice flaw in this method.
If your reader has > 1 lines then you always display the last value from the reader.object

Add the javascript from you code behind page.
this.ClientScript.RegisterClientScriptBlock(this.Page.GetType(), "key", "document.getElementById('" + txtbox1.clientId " + ');", true);
Otherwise you might not have the correct clientid in your javascript.

Hi all,
I am working with a team on a web project and every one of us is using internal documentation for all the classes and functions we are using by writting inside the following:
''' <summary><br />
''' Description of the class<br />
''' </summary><br />
''' <param name="ip"></param><br />
''' <param name="url"></param><br />
''' <param name="currentError"></param><br />
''' <param name="errorDate"></param><br />
''' <remarks></remarks><br />
Is there a way that i can extract all the documentation from the application and save it as a soft copy.
thanks
|
|
|
|
|
Yes,
You can , use XML Documention for that.
eg.
///<summary>
///This is A sample Example , Describe your function
///</Sumary>
Void MyFunction()
{
//Your Funmction
}
Now, From Project Property page -> Build
In XML Documentation file -> Give the XML File path
Build the Application.
Check in \bin\Relase file there is a XML file generated.
That's all.
Try to workout on XML Documentation , there are losts of material are available in .net, i have just give u the idea how to start.
Good luck
Best Regards
