I am trying to find a code snippet that reads a sql server db and retrieves an image from a table and converts it into a thumbnail image. I'm looking for VB.Net code that does this and I can't find anything.

View 3 RepliesI have written the code below to generate an XML document and it works a charm however the smallest snippet of code is causing me a major headache:
SNOMlabel.text += 1
For some reason this is doubling up and SNOMlabel equals 2 i have debugged the code on this line and it appears to be something to do with when it leaves the Sub btnSave_Click and enters and returns from CreateBookNode, CreateBookNode2, CreateBookNode3.
Code:
Protected Sub btnSave_Click(ByVal sender As Object, ByVal e As EventArgs) Handles btnSave.Click
' Name of xml file to create
Dim subs = SubscriberID.Text
Dim name2 As String
Dim fdate As String
Dim length As Integer
length = Len(Page.User.Identity.Name)..........

When debugging my application, I m getting an application level error in global.asax file. The Server.GetLastError() reads "File does not exist." but thats it. No more details on the filename or the location where the code is trying to find a file. I commented out the application_error method, with a hope that the exception would be thrown when the debug the application, but no errors were thrown. How do i find the source of the error, cos I want to resolve this issue by either putting the file that the application is looking for or by completely removing the code that is referencing the file.
View 7 RepliesI receive lists from a web service and then I convert the lists to datatable and then I add the datatables to a dataset and from there I get the xml from the dataset where I can save it into a sql database. But the problem is that the xml has /r/n between all attributes and elements. I dont know how to get this out of the xml. Can this be because of my converter. If so can anyone give me a better way to get multiple lists into a dataset.

I use the above code to return records from database. The above snippet would run in web application which expected to have around 5000 visitors daily. The records returned reach 20,000 or
over. The returned records are viewed (read-only) in paged GridView.
Would it be better to use DataReader instead of DataTable?
NOTE: two columns in the GridView are hyperlinked.
I have a couple of related questions:
1. How do I add a "main title" to only the first page of the Gridview when I print it?
2. How do I change the font on my Gridview printout?

I have a dropdown on my page that reads a value from the users session.
ddlMemberGender.SelectedValue = Session("MemberGender")
there are two choices (obviously) : Man and Woman
So when the Session value sets the DropDown to Male it works fine. But if the user changes the DropDown to Woman in my code behind it still reads "Male" as the value... for example:
Response.Redirect("/post.aspx?Gender=" + ddlSearchMemberGender.SelectedValue) will still read the selected value that was set previously instead of the value it was changed to.
I have a website hosted with sql 2008 database on Godaddy. Here's my problem descriptionbefore I actually begin implementing.Entries are made in a table named "XYZ" by a third party program. Now, there are multipleclients (could be asp.net ajax web based or vb.net desktop clients which I have not decided yet) who
read data from this "XYZ" table every 10-15 seconds. The connection string used by these clients would be same. If I have 10000-20000 clients making connections and querying same table, would that cause any breakdown? Since my connection string is same, connection pooling isautomatically in place.
What else do you think I need to take care of? Or is there any better way to implement this setup?Also, should I go for asp.net ajax client implementation or vb.net(c#) client implemtation ?Your inputs would be highly helpful to me. I am looking for a medium to long term solution to thissetup.
I have couple of DDL's which let user choose couple of different values from it. Once the user has made his selection he clicks on the "Submit" buttion which redirects the user to the other page, which then displays table from backend SQL DB. The pages are named Page1.aspx and Page2.aspx resp. I am using Querystring to carry forward the values of the DDL's to Page2.aspx.
How can i modify the query in such a way that even if one of the DDL's is left blank the Query would ignore that and shall produce the table considering value of DDL2 in the where clause. In case both the DDL's are empty then the query will not have a where clause and shall showcase the complete table as such. I've written a query for this but it's not working the way it shoul.Here is my code for the SQLDataSource: [Code]....

View 1 RepliesI'm trying to define a computed column that will contain an auto-incremented number. In other words, I want it to work exactly like identity, but since I can have only one identity column per table, I wanted to make a computed column that reads its latest value and increment it by 1.

how i can find the panel id in code behind if i know id="textid
my output
<panel1>
<panel2>
<textid> aaaaaa</textid>
</panel2>
</panel1>
So, in my example below, "InputDate'" is an input type=text, "DateColumn" is a TD within a table with a class of "DateColumn".
Read the value of a discreet texbox:
var inputVal = $('#InputDate').val();
Read the value of a div within a table....
This works:
$('#theTable .DateColumn').each(function() {
var rowDate = Date.parse($(this)[0].innerHTML);
});
This doesn't:
$('#theTable .DateColumn').each(function() {
var rowDate = Date.parse($(this)[0].innerHTML());
});
The difference is the "()" after innerHTML. This behavior seems syntactically inconsistent between how you read a value from a textbox and how you read it from a div. I'm ok with sometimes, depending on the type of control, having to read .val vs .innerHTML vs.whateverElseDependingOnTheTypeOfControl...but this example leads me to believe I now must also memorize whether I need trailing brackets or not on each property/method.
So for a person like me who is relatively new to jQuery/Javascript....I seem to have figured out this particular anomaly, in this instance, but is there a convention I am missing out on, or does a person have to literally have to memorize whether each method does or does not need brackets?
How do I insert a snippet to change a hyper link ' insert' to a button image?

How do you currently find the balance between javascript and code behind. I have recently come across some extremely bad (in my eyes) legacy code that lends itself to chaos (someHugeJavafile.js) which contains a lot of the logic used in many of the pages.
Let's say for example that you have a Form that you need to complete.
1. Personal Details
2. Address Information
3. Little bit more about yourself
You don't want to overload the person with all the fields at once, so you decide to split it up into steps.
Do you create separate pages for Personal Details, Address Information and a Little bit more about yourself.
Do you create controls for each and hide and show them on a postback or using some update panel?
Do you use jQuery and do some checking to ensure that the person has completed the required fields for the step and show the new "section" by using .show()?
I have a number of pages

Why neither method can't find a control?
I am developing a web application that will allow the customer to enter a personalized message, which will then be converted to HTML. Well, the problem is that I can not allow the insertion of Javascript code. So I need a method that filters the text, searching for and remove it. I think the regular expressions to solve my problem, but I'm having difficulty building.
