Multiple Field Validation - VB.NET Patrice in Irvine8-Jun-07 8:50 Patrice in Irvine 8-Jun-07 8:50  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 Re: Multiple Field Validation - VB.NET Not Active8-Jun-07 9:08 Not Active 8-Jun-07 9:08  Don't repeat the same question.

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? Re: learning ASP.NET ToddHileHoffer8-Jun-07 8:21 ToddHileHoffer 8-Jun-07 8:21  ASP.Net is tricky compared to windows apps. You need to learn HTML, JavaScript and CSS. The tricky part is making a nice user interface in a web page. This is a good site. http://asp.net/learn/dataaccess/default.aspx?tabid=63 I suggest you learn the page life cycle. http://www.15seconds.com/issue/020102.htm One more thing to learn is State management or how to get data from one page to another. http://support.microsoft.com/kb/307598 Good Luck GameFly free trial Re: learning ASP.NET Kevin McFarlane8-Jun-07 11:09 Kevin McFarlane 8-Jun-07 11:09  ToddHileHoffer wrote: ASP.Net is tricky compared to windows apps.

Kevin http BASIC authentication question Bkaufman438-Jun-07 7:13 Bkaufman43 8-Jun-07 7:13  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! Bruce K.

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. Bruce K. Client-side validation of All fields on form Patrice in Irvine8-Jun-07 6:56 Patrice in Irvine 8-Jun-07 6:56  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.

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 access session using the instance of another page? Ashokkuma8-Jun-07 2:10 Ashokkuma 8-Jun-07 2:10  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??? Ashokkuma Re: How to access session using the instance of another page? Chetan Ranpariya8-Jun-07 2:42 Chetan Ranpariya 8-Jun-07 2:42  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
