Is there a way to validate several fields on a form with ONE validation control?
The scenario - 10 fields, at least one of them needs an entry before proceeding to the next page.
I need to check if all fields are null (empty, blank) and return an error message

I am planning to learn ASP.NET to broaden my .net skills. Is ASP.NET easy to learn? How long did it take to get a grasp on how to use it? Are there any tutorials or websites that will help me achieve my goal?

When .NET first came out I found it much easier to get to grips with Windows apps. than ASP.NET apps. The latter was especially confusing having had some experience with classic ASP.

I am relatively new to Asp.Net. Here's my question:
I need to do a simple http POST to a service URL (at a different domain) with all the parameters in the query string. For security purposes the service URL is using http BASIC authentication under https.
I need to add an "Authorization" header with a Base64 encoded username and password to gain access to the service.
For the sake of illustration, assuming the login is: Abcdef and the password is aBC123abc -- what would the coding look like (in VB)? Where specifically would the coding be placed?
Thanks!

String auth = userID + ":" + password;
byte[] binaryData = Encoding.UTF8.GetBytes(auth);
auth = Convert.ToBase64String(binaryData); // Using base64 encoding
auth = "Basic " + auth; //This specifies it to use Basic Authentication
// Prepare web request
HttpWebRequest webRequest = (HttpWebRequest)WebRequest.Create(myURL);
// Add the standard headers
webRequest.Method = "POST";
webRequest.ContentType = "application/x-www-form-urlencoded";
webRequest.ContentLength = 0;
// Add this additional header
webRequest.Headers[“AUTHORIZATION”] = auth;
HttpWebResponse webResponse = (HttpWebResponse)webRequest.GetResponse();

Thank you very much Felipe!
Ok - here come the "dumb" questions - sorry!
Where do I place this code?:
String auth = userID + ":" + password;
byte[] binaryData = Encoding.UTF8.GetBytes(auth);
auth = Convert.ToBase64String(binaryData); // Using base64 encoding
auth = "Basic " + auth; //This specifies it to use Basic Authentication
Does this go in the web.config file? If not where?
Same question for:
// Prepare web request
HttpWebRequest webRequest = (HttpWebRequest)WebRequest.Create(myURL);
Where do I place this code?
And lastly are the standard (and additional) headers added in the document headers section of IIs in the virtual directory that contains the asp.net form page? If not where?
Thanks for your patience.

Say I have 10 fields. Is there a way to check that all 10 fields are not null on the client? I am able to check on the server but would prefer to do client-side checking. The standard ASP.Net validation controls seem to be for only one field at a time.
Thank you.

Use a CustomValidator control and use the ClientValidationFunction to check all fields you are interested in.

Hello Mark,
I posted an updated question that may be clearer than my original question.
Here it is...
Is there a way to validate several fields on a form with ONE validation control?
The scenario - 10 fields, at least one of them needs an entry before proceeding to the next page.
I need to check if all fields are null (empty, blank) and return an error message
I just checked out the ClientValidationFunction but it seems(to me) that I can still only validate against one field at a time. Is that true or do you think I can use this function to validate against multiple fields with ONE validation control?
Thank you for your earlier response.

How to create and use assemblies in .net? can anybody explain me how to use assemblies?
|
|
|
|
|
|
in .net .exe & .dll files are known as assemblies
and u can make .exe by creating a windows application or console application etc..
and u can make a .dll by creating a class library
|
|
|
|
|
Add the the Assembly you want to use as a reference to your application and include its namespace and use it .....
If you want to create a assembly it depends on which tyoe of application are you devloping
Thanks and Regards

I have three pages: First.ascx, Second.ascx and Third.ascx
In First.ascx, im setting a session variable to some value
Private Sub Page_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Session("xyz")="SomeValue"
End Sub
In Second.ascx, i have a function to access the session value
Public Function RetrieveFromSession() As String
Dim str As String
str=Session("xyz")
return str
End Function
Private Sub Page_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Dim SessionValue As String
SessionValue = RetrieveFromSession()
End Sub
This is working perfectly fine. Im able to access the session this way.
But in Third.ascx, im creating an instance for Second
Private Sub Page_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Dim objSecond As New Second()
Dim strSessionValue As String
strSessionValue = objSecond.RetrieveFromSession()
End Sub
The function RetrieveFromSession() is called properly, but inside the function
the line str=Session("xyz") goes to error. It says "Object reference not set to an instance of an object."
But, im able to access the session directly. ie.,
Private Sub Page_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Dim strSessionValue As String
strSessionValue = Session("xyz")
End Sub
This is working fine.
But, i want third.ascx to access the session using objSecond.RetrieveFromSession() function.
How can this be rectified.
Can anybody help me in this regard???

Hi,
Your approach is not correct. and it won't work at all.
When u set session value it will be accessible from current objects of all the ascx.
Here u r creating new object of second. When u do this a new session will start for that instace and that new session will not have any value obviously and that's why it is giving you error.
Its better that you access your session value by conventional way.
and I dont understand why you want to go by "objSecond.RetrieveFromSession()" this way.
Is there any specific requirement?
Thanks and Regards,
Chetan Ranpariya
