ASP.NET linkbutton in a frame

This tip is how to use a linkbutton inside a frame . It’s harder than it sounds since the linkbutton doesn’t have a target property.

ASP tip of the day

The code we use presents a random tip by using ASP and a little trickery. In addition, our code never presents the same tip twice until all the tips have been presented.

Here’s how we do it…

First, let’s look at the structure of the SQL Server table that holds all the tips (KB).

ID int
Summary varchar(255)
FileName varchar(255)
Presented bit

ID is the primary key for the table and is used to reference each tip. The Summary column contains text that is used to summarize the tip and is what we show the user for a short description of the tip. FileName holds the actual file name of the page for the tip. The Presented column is either 1 or 0, indicating if the tip has already been presented.

The overall structure of the ASP code used to display the tips has several steps:

setup the db connection

’setup the db connection

Set dbTip = Server.CreateObject(”ADODB.Connection”)

dbTip.Open sDSN

Initialize the VBScript number randomizer

‘Init the number randomizer

Randomize

Get the total number of tips that have not been presented

‘get the total number of tips

sSQL = “SELECT Count(ID) AS CountOfTipID FROM KB WHERE Presented = 0″

Set rsTip = dbTip.Execute(sSQL)

iTipUpperBounds = rsTip(”CountOfTipID”)

If all the tips have been presented, reset the presented flag on all the tips

‘make sure we have records to present

If iTipUpperBounds = 0 Then

‘all the records have been presented…

‘we need to clear the dirty flag

sSQL = “UPDATE KB SET Presented = 0″

dbTip.Execute(sSQL)

‘get the total number of tips…again, now that we’ve cleared dirty flag

sSQL = “SELECT Count(ID) AS CountOfTipID FROM KB”

Set rsTip = dbTip.Execute(sSQL)

iTipUpperBounds = rsTip(”CountOfTipID”)
End
If

Pick a random number between 1 and the total number of tips that have not been presented

‘pick a random tip

iTipNumber = Int(((iTipUpperBounds -1) – 0 + 1) * Rnd + 0)

Get all the tips that have not been presented

‘get the tips

sSQL = “SELECT ID, Summary, FileName FROM KB WHERE Presented=0″

Set rsTip = dbTip.Execute(sSQL)

Move the cursor to the random number using the Move method.

’select the random tip

rsTip.Move iTipNumber

Read the record and present the data

” target=”_top”>Click
here for the details…
Update the record to indicate that it’s been presented
‘turn the presented flag on for the record

sSQL = “UPDATE KB SET Presented = 1 WHERE ID = ” & rsTip(”KBID”)

dbTip.Execute(sSQL)

Clean up

‘clean up recordset

rsTip.Close

Set rsTip = Nothing

dbTip.Close

Set dbTip = Nothing
