what i want to do is to get the current ip i have (with a site as, http://whatismyip.com/) and send it to paypal sandbox so i can get a response (of course i haven't started the paypal code but i first need to be able to get a communication from paypal,non?)Ok the problem is that if i start a new web site on IIS, hit the current ip, i get my router administration console as a response.I have tried to change the port on a new site to 81 or 82 or 83 but i get a page not found.
I was having trouble getting my shopping cart to connect to paypal. So I wrote a simple webform that has one button and one label. If I comment out the response.redirect(url) and look at the content that get written to Lable1.Text it looks find. Also, if I copy the content of the label and paste it into my web browser it goes to Paypal and displays correctly.
However, if I uncomment the response.redirect(url) I get the following error: ERROR: Unable to Send to PayPal - Thread was being aborted.
I am testing from localhost??? Should I be able to test this from localhost?
I have put ??? where my Sandbox email address is.....I don't know if letting other see that or not is an issue....otherwise I would have left it in for someone to try this code.
[Code]....
This is what displays in the lable1.text when response.redirect is commented out
If I change if (!IsPostBack) GridView1.DataBind(); to GridView1.DataBind(); and try to put GridView into Edit mode by clicking btnEdit, then I get the exception: Invalid postback or callback argument. Event validation is enabled using in configuration or <%@ Page EnableEventValidation="true" %> in a page. For security purposes, this feature verifies that arguments to postback or callback events originate from the server control that originally rendered them. If the data is valid and expected, use the ClientScriptManager.RegisterForEventValidation method in order to register the postback or callback data for validation. But if I set EnableEventValidation to false, then GridView1 won't enter edit mode ( ie - GridView1_RowEditing doesn't get called ). BTW - same problem also occurs with other databound controls ( DataList, DetailsView ) Page. EnableEventValidation gets or sets a value indicating whether the page validates postback and callback events. When the ableEventValidation property is set to true, ASP.NET validates that a control event originated from the user interface that was rendered by that control. A control registers its events during rendering and then validates the events during postback or callback handling.
a) Why must postback and callback events be evaluated? and how exactly does evaluation happen? b) Why would calling GridView1.Databind() on each postback cause exception when trying to put it into edit mode? c) I also don't see any reasons why disabling EnableEventValidation prevents GridView from entering edit mode?! Thus why did.
„Use the PostBackTrigger control to enable controls inside an UpdatePanel to cause a postback instead of performing an asynchronous postback."
I made simple application and I do not see difference between using PostBackTrigger and standard postback.
I have three buttons: two inside update panel and one outside update panel. When I click btnUpdateAsync in event handler I set text property of lblUpdatePanel and lblNoUpdatePanel and only lbl that is inside update panel is chaned if web browswer - so this is ok.
Whant I click btnUpdateInUpdatePanelSync all page is refreshed and both lablels are changed in web browser.
When I click btnUpdateOutsideUpdatePanel I see the same behavior.
If I used button that is not associated with PostBackTrigger I would get the same behavior - so what is the purpose of PostBackTrigger?
During a recent interview the following question was asked.
- A Master page which contains - An ASPX web form page which contains - A Web User Control inside the page which contains - A button to fire some code in a button_click event
The Init Event will fire (Inner Most to Outer Most)
aspx.page Begin Init -> Inside user control Page_Init -> Inside master page Page_Init -> Inside lifecycle page Page_Init aspx.page End Init
and Load Event will fire
aspx.page Begin Load -> Inside lifecycle page Page_Load -> Inside master page Page_Load -> Inside user control Page_Load aspx.page End Load
Why does ASP.NET framework support different execution order in Load() and Init().This was the question asked in interview.I have no idea about what the interviewer expecting from me.
If you have a very large stored procedure, is it okay to just use the commands just once in the script? ANSI_NULLS ON and QUOTED_IDENTIFIERS ON?I really don't understand the purpose of these commands?
What is the purpose and proper use of the max-length property on text fields?
The application I'm working on limits numeric fields to 6 characters... which doesn't work very well for entering millions of dollars... which is why I'm "fixing" it.
We are going to write an entire new application for a reservation system. In this system experts specify their free time in elaborated calendar and users seek them through searched and finally reserve the expert and his time.
We prefer to find an open source program like this and try to evolve it instead of creating it from scratch. In this manner our time is saved and that open source program will be completer too.
