I have a problem with a sql query. Through the query I am trying to search database for any occurrences of string (can be anything) in a column using the SQL LIKE command. The problem is that it works fine for most of the strings say john, jim, ji"m , but does not work when i include the following characters which are ( ' , { , } , and a single quotation mark). MYSQL query takes care of these special cases by putting them in [] block whenever user enters them .But i am getting the following error when i go to query the database using the GetSelectCommand() in VB.NET
Exception Details: System.ApplicationException: Number of values provided must be equal to the number of placeholders in query.I have checked the query over and over again .. but its fine .My database server is Sql Server 2008.So my application throws the exception in this command:
Using reader As MustDisposeDataReader = _
pmSystem.DatabaseManager.GetSelectCommand(selectStatementBuilder.ToString(), New Object() {})
Where MustDisposeDataReader is an instance of a class in an internally developed library, which inherits from System.Object. pmSystem is an instance of the class PlanManagerSystem which implements the commandlayer. GetSelectCommand() takes the select command

i have seen google chrome, whenever you open a new tab, it will show you the last 8 pages that you have visited. I want to do a similar thing, except i have a vb.net code behind the .aspx file, which shall give me a list of URL's called form the database. When the page is loaded the URL's are displayed on it. what i need my code to do is to pick up these URL's, on the background open a web browser, take a snapshot of it and save it, and display it on the screen. dont recommend IFrames cause I need a snapshot and not an actual running site in the small snapshot.
View 2 RepliesAssume that there is a web site which includes 3 different pages. I want to show a text one of the pages randomly, with is formatted with css.
For instance the pages are below:
hello-world.aspx
hi-sun.aspx
good-night-moon.aspx
* When John enters to the site, the text will appear on hi-sun.aspx,
* When Elmander enters to the site, the text will appear on hello-world.aspx
And when one enters the page which includes a special text, even if come again, it shouldn't appear.
Psedue Code:
if(Session["first"] == "1"){
//show the text in a random page }
else {
//text.visible = false
}
In the if block how can I supply the text in a random page. (it shouldn't appear in every page, should appear only one page).

View 2 RepliesIm working on writing a program for doing standard deviation and as of right now im running into one slight issue with subtracting my mean from the original numbers. I will post most of my code so you can get an over view but i mostly just want help on this one little part for now. Im going to be making a website for school and put some programming stuff on it so i wanted to make just some random programs for it so this is school related but not really homework. It's line 26 and 27 that this is relating to. When i put a stop in my code and look at the result of arrayDifferences it gives me 0.0 when it should be -1. I know i can go this route and say arrayDifferences(1) = arrayDifferences(1) - arrayAvg but seeing as how i want this to be a random number of numbers input by the user i cant do that.
