Trying To Pop Up A Window Based On VB Code Result? www.vbforums.com

I have a web page where I am hoping to insert a single line of code. This code will execute an aspx page that will determine whether or not the popup should occur, and then if so, pop up the window.In the main page I am using this line of code: <script language="JavaScript" type="text/javascript" src="Check.aspx?sid=2383"></script> When I step through this, the check.aspx page is hit, it goes through the check logic, and returns a value of TRUE. All of the code behind in the check.aspx page is VB. I can step through every line of the code with no problem and see that the return value is true.In the html section of the check.aspx I have: <% If PopTrue Then%> <script type="text/javascript" language="javascript"> window.open('Display.aspx','Display') </script> <% End If%> If I step through the code in Visual Studio, I see the window.open command is being hit, yet the window never opens. This seems very odd. Am I missing something?


.Net : Link Between Aspx And Code? forums.asp.net

VS 2008 - Converting Between Web Project To A Website www.vbforums.com

I am not sure if I am using the correct terms. But it is possible to create an asp.net website at least three ways. 1) Where the form and code behind code are in the same file 2) Where the form and code behind code are in separate files, resulting in 2 files for each page (*.aspx, and *.aspx.vb) 3) Where you upon the site up as a project, but insert web pages. This approach results in three files per page (*.aspx, *.aspx.designer.vb, and *.aspx.vb) My problem is I have a site which is done the third way and I would like to switch it to the second. Is there any automated way to do this, or do I have to do it page by page. What I can do is Open a new site with Create Website, insert a page, and then do some copy and paste.

My website has only 2 pages, and both use the same class (same class name, exactly same syntax) but it has been copied and pasted and the 2 aspx pages (and aspx.cs pages) are not referencing each other. In other words, both aspx.cs pages (called page1.aspx.cs and page2.aspx.cs) has the class public class CheckValue { //content return true; } Both the aspx pages reference the 'inherits' files seperately: <%@ Page Language="C#" CodeFile="page1.aspx.cs" Inherits="_1" %> and my code behind public partial class _1 : System.Web.UI.Page and for my second page <%@ Page Language="C#" CodeFile="page2.aspx.cs" Inherits="_2" %> and my code behind public partial class _2 : System.Web.UI.Page I don't use the .resx file.

Asp.net - Executing A WebMethod From Javascript? stackoverflow.com

Trying to use javascript and ajax to execute the same code my vb had.I put in a script manager, set EnablePageMethods to true, added a static subroutine, and referred to it in my javascript function (BTW -- this seems a lot of work just to execute an existing subroutine). The javascript calls my code-behind and it almost works.Problem is, now I'm getting a NullReferenceException when SimulatePrintBatchClick tries to do anything with the controls. Error is 'Object reference not set to an instance of an object', line is 'pnlVars.Controls.Clear' Here's the code from UW.aspx: <WebMethod()> _ Public Shared Sub PrintBatchFromJSWM() Dim UWI As New UW [code].... when I run the above code in PrintBatch_Click it all executes just fine.

Originally this code was handled by an ASP/VB button, but the specs have called for it to be deleted.

BusinessLogicLayer do proecessign in it self and for data it calls DataAccessLayer funtions. -Web forms do not calls directly DAL. -CustomTypesLayer is shared by all layers. I though it may be MVC or MVP but pages have there code behind files as well which are confusing me.

How To Load The Webpage One Bit At A Time forums.asp.net

I have an aspx web page, which has a 'frame' (logo, menu bars, etc.) and then the central where all content is under a form/div element. To populate that content I make calls to different servers, and then I display it. I make these calls using the VB.net code behind the page, with several functions that get called from the 'Page_Load' function. The thing is, until all content has been downloaded (that is, all calls to external servers have returned and I can populate the data div), the page doesn't display anything. Instead it stays there, waiting for the response, and when it has all the available data finally renders the page. What I'd like to do, in order to avoid long waits, is to display at least the menu, logo, etc. while the server is waiting for the rest of the data to return. I think this is the way most web pages work, and would like some advise as to how implement it.

Threads In .vb Class Not Working For Web App forums.asp.net

I have a web app that I'm writing in asp.net, with vb code behind.

Below is a small section of my code. It used to be that when the "botThread.Start()" method was called, the page would redirect to success.aspx, and work on the SQL query (RunBots()) thread in the background.

C# Dont Reference Sqlreader In Client Portion Then Where? stackoverflow.com

Assume I have a form that has say 5 text boxes and I need to pull some data from a database then set those 5 text boxes with that data.So assume I have 3 basic layers: the code behind for a default.aspx page a BLL class that contacts the DAL and a data access layer (DAL)But I've heard and read that the default.aspx page should not know about sqldatareader, in fact you probably dont want to add the sqlclient namesspace to the default.aspx code behind page. [code] Then the BLL would simply call the DAL to call a stored procedure in SQL Server and do a CommandObject.ExecuteReader, get the results pass it back to BLL and BLL would then send it to the code behind page of default.aspx.I can provide full source code if that doesn't make sense. My question is if its bad that default.aspx actually declares and knows about an SQL Data Reader then what is the better way to do this? What datatype should I be using to avoid having an sqldatareader in my interface code ?

Web Forms :: Accessing Stored Procedure Of SQL Server From Popup Window? forums.asp.net

I have a parent window parent.aspx and a popup window popup.aspx. parent.aspx has a confirm button which on click open popup.aspx. This popup.aspx holds a filled application form like leave application form of employees and a email sending button. That button on click send emails to the specified email addresses with attachment. The popup.aspx has a javascript function sendResponse() which call another javascript function display() of parent.aspx after sending the email. The display() function display a message by Label control regarding the email sending i.e., whether or not this email sending operation is successful. The sendResponse() function after calling display() close the popup.aspx window. I have successfully did all the aforesaid jobs. Now the scenario is that I have a database which is holding various leave information like casual leave, medical leave etc of employees. After sending email successfully I have to update this database.It will be better to tell in this context that the email sending portion of my cs script is : [Code].... this info string is passed to the sendResponse() javascript function as : [Code].... And the sendResponse() function is : [Code].... Now the problem is, in which portion or when I do update the database. Should I update the database in try-catch block of email sending or from sendResponse() function?I have tried to call C# function UpdateDatabase() from sendRespose() as shown here. But this static method is creating too many problems like the popup.aspx is not closing automatically, if I try to call another C# non-static method from the static UpdateDatabase() method to close the window I have to call it by creating a new instance of that page, which is eventually not closing the popup window. Can I call stored procedure from javascript function sendResponse() and pass parameters to it? If so how can I call it?
