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.
I am using SQL Server 2008 Web Edition and it seems my SQL queries are automagically having the double quotes replaced with ' + CHAR(34) + '. I am trying to pin down why this is happening, I am using Delphi with ASP.NET and using the ADO.NET object for the SQL.
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?
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 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?
i have a radeditor in my webform and it posts back. if i type any thing in the editor and press enter key for new line and then use any control in the page which reloads the page, then the next line character in the editor gets replaced by $0 and other text remains same as earlier. it happens in SAFARI.
Ex. aasdads dsdsds the above text replaced by: aasdads$0dsdsds$0
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.

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?
I have hosted a site on server. Problem is, content of a particular .aspx file (index.aspx/content.aspx) is periodically replaced by clinet side HTML code(the source we see in browser by right click>view source). What can be reason behind this?
I am facing one issue with MaskEditExtender (Ajax Control) control. If anyone knows solution please let me know.
I am having one TextBox aassociated with mask edit extender control. While editing the textbox values, value getting replaced instead of added.
Ex: Supose in my textbox if i have value as 1234, then i want to make it as 12534 so i entered 5 after 2. But am not getting result as expected, its showing as 1254 (means 3 is getting replaced with 5).
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?
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?
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.
i am looking for a solution using IN-Operator with LINQ TO SQL. I have found many examples after searching but no exemple which is using a Textbox.In my Textbox i put my ids 2,4,6,7,9 and after clicking the button, it have to show me my Records. But it does not.The error-message shwos me a wrong format.Ausnahmedetails: System.FormatException: Die Eingabezeichenfolge hat das falsche Format.
Zeile 5: Dim result As String = "" Zeile 6: Dim intText As String = Me.tbKursid.Text >>>>>>>> Zeile 7: Dim myText() As Integer = {Convert.ToInt32(intText)} Zeile 8: Dim db As New seminarDataContext Zeile 9: Dim daten = From c In db.vSchluessel _
If i use Dim myText() As Integer = {1,4,5,6} then it runs without problems. What is wrong?
I have a local collection of record Id's (integers).I need to retrieve records that have every one of their child records' ids in that local collection. Here is my query:
public List<int> OwnerIds { get; private set; } ... filteredPatches = from p in filteredPatches where OwnerIds.All(o => p.PatchesOwners.Select(x => x.OwnerId).Contains(o)) select p;
[code]...
I am getting this error:Local sequence cannot be used in Linq to SQL mplementation of query operators except the Contains() operator.I understand that.All() isn't supported by Linq to SQL, but is there a way to do what I am trying to do?
