Replaced Nested Ifs With AndAlso Operator

Jun 3, 2010

I recently found out about the andAlso operator, and I understood that it will only evaluate the right condition if the left is true, I thought this could help tidy my code so replaced nested ifs with AndAlso.

Private ds As DataSet
-----------
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
ds = nothing
If Not ds.Tables(0) Is Nothing AndAlso ds.Tables(0).Rows.Count > 0 Then
end if
end sub

I deliberately set my ds to nothing to replicate a database error and it gave me an object reference error.

Configuration :: IIS Has To Be Restarted When One Of The DLLs Is Replaced?

Mar 17, 2010

I recently noticed that when a dll is replaced at my web site, the site will take a long time to come back, even though the dll is only used by limited pages. I generally have to reset IIS to make the web site come back faster. Is this the normal behavior? or some settings need to be ajusted to avoid this?

JQuery Replaced Div Stops Responding To Mouseclick

Nov 9, 2010

I am trying to replace a value in a drop down box. The replacing works fine (after help from this fine community) but afterwards the slide function stops working. I can't find any errors so I'm asking if this could be related to how jQuery and javaScript works? Are elements "mapped" to the DOM on load and if so; would that imply that replacing a div with another div would result in jQuery loosing track of the divs? I use this code to check if a div is clicked:

$(document).ready(function () {
$('.button_slide').click(function () {
var num = $(this).attr('rel');
$('div.content_slide:not(.' + num + ') ').slideUp(400);
$('div.' + num).slideToggle(400);
});
return false;
});

This is the div:

<div class="button_slide" rel="slide1">Alts:</div>
<div class="content_slide slide1">
<input id="Button1" rel="slide1" class="button_vertical click_button" type="button" value="2" size="10px" />
<input id="Button2" rel="slide1" class="button_vertical click_button" type="button" value="3" />
</div>

This is the jQuery that drops down the box:
$(function () {
$('.click_button').click(function () {
var num = $(this).attr('rel');
$('.button_slide[rel="' + num + '"]').replaceWith("<div class='button_slide' rel='" + num + "' >" + $(this).val() + "</div>");
$('div.content_slide').slideUp(600);
});
});

I'm pulling my hair on this one and jQuery isn't my stronger side... How would you solve this?

Can Create New PDF Files Based On A Template Where Some Text Will Be Replaced?

Sep 5, 2010

I'm developing a CMS aplication in ASP .Net using WebForms and I'm looking for a way to create new PDF files based on a template.

This feature will be used to generate contracts where some placeholders will be replaced with the customer data.

Edited: The templates will be static, the main content will never change from customer to customer, only some text in the beginning that will contain the placeholders to recive the customer data. The catch is that I must allow the owner of the application to upload new templates in PDF, with the predetermined placeholders in it to allow the replacement to occur.

Server Side Web Programming Model Replaced By JavaScript / Ajax?

Dec 14, 2010

ASP.NET server controls has a few categories, for example, normal ones e.g. TextBox, Button which can be done in HTML/JS; Validation controls: can be done in JS; Login controls: I have seen them implemented in JS. Data bound controls: not sure, but maybe JS can work directly with databases, implementing controls like photo slider. So in the time span of next 5-10 years, will server-side web programming model fall out of mainstream and be replaced by JS/Ajax that interacts directly with databases?

Security :: Login Control Stops Working Requiring It Be Deleted And Replaced

Mar 3, 2011

I have found that eventually the login control I place on my page will not authenticate. The solution appears to be to delete it and replace it with a new instance. Obviously this is not tenable. Can someone enlighten me as to why it might stop working for no apparent reason such that simply deleting it and putting a new instance in place will restore functionality? Update: I find it very sensitive. I just did the above described action, got it working again, found that the Authenticate event was no longer properly wired and tried to fix it by removing the '1' from the Authenticate1 in this line. That was sufficient to kill the control which required me to once again delete it and replace. I cannot believe the login control is that sensitive or no one would touch it. What gives?

C# - Proper Implementation Of Nested API Calls Using Connection Pool And Nested Transactions?

Jan 4, 2010

I need to know the best way to do the following. I have nested business level APIs (say level 1 & level 2). L1 needs to call L2. Both APIs use the database layer directly at their own nesting levels.

Now, in the database layer, I fetch the db connection from the pool each time as follows:

SqlConnection conn = new SqlConnection(connString);
conn.Open();

Is it proper to fetch the db connection each time on every DB level call as above? I know it will return a connection from the ASP.NET connection pool. However, wouldn't it be better to maintain the same DB connection throughout the nested calls (or throughout the current http request lifetime)? Will fetching a connection from the pool each time cause issues with nested TransactionScopes?

Forms Data Controls :: Looking For Clean Approach To Building Nested Datalist Or Nested Gridview

Jun 17, 2010

Is there a better, cleaner way to do this in ASP.NET 2.0?

An ASP.NET 2.0 page displays a datalist of records. Each record can have many dates, so the dates are in a nested gridview (I chose a gridview over a datalist here because we want to be able to delete a date and this is easier done in a gridview). The parent record can never be deleted.

The display works fine: the nested gridview gets its datasource during the parent datalist's OnItemDataBound event.

The problem: the nested gridview's delete function. The date gets deleted without a problem (handled in the OnRowDeleting event), but somehow the redisplay is untying all the other nested gridviews from their datasources. The delete does not appear to cause a page postback, so I don't know how the other nested gridviews are losing their datasources.

Bit Shift Operator Behavior For Int64?

Feb 12, 2011

I need to use a field of 64 bits (32 is not long enough). I used the following page to see the effects of bit shifting when using the Int64 data type:

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<%@ Page Language="VB" WarningLevel="1" Explicit="true" Strict="true" %>

<script language="VB" runat="server">
private sub do_test()
dim bit_no as Integer
dim info as Int64


' Show min value as binary ...
info = Int64.MinValue
response.write( String.Format( "Int64.MinValue = {0}<br>", info ) )
response.write( String.Format( "Int64.MinValue (binary) = {0}<br>", Convert.ToString( info, 2 ) ) )
response.write( "<br>" )

' Show max value as binary ...
info = Int64.MaxValue
response.write( String.Format( "Int64.MaxValue = {0}<br>", info ) )
response.write( String.Format( "Int64.MaxValue (binary) = {0}<br>", Convert.ToString( info, 2 ) ) )
response.write( "<br>" )


response.write( "Bit Shift Test" )
response.write( "<br>" )

for bit_no = 0 to 63
info = 1 << bit_no
response.write( String.Format( "1 << {0} = {1}<br>", bit_no, info ) )
next

end sub
</script>
<html>
<body>
<% do_test() %>

The output of the page is:
