View 10 RepliesI have a page which consists of a grid and add new button. When the user clicks add new button he gets several fields to be entered. So, when he clicks submit I usually write a query which checks if there is an entry already in the database. In this case, I succeeded.

View 3 Repliesthis is my aspx page code :
<a runat="server" id="hlkmail"><img src="../images/send_mail_icon.jpg" alt="" /></a>
<a runat="server" id="hlkgallery"><img src="../images/galleryl_icon.jpg" alt="" /></a>
this is code behind (aspx.vb) :
hlkmail.HRef = "sndmail.aspx?Clientname=" & clientName
hlkgallery.HRef = "pgallery.aspx?Clientname=" & clientName
above code shows fixed images.
i want to display image dynamiccally depending upon the db value.
i have a stored proc that returns hasmail ='true/false' and hasgallery='true/false' from database.
if true i want to display send_mail_icon.jpg else send_mail_icon_watermark.jpg
and gallery_icon else gallery_icon_watermark.jpg. i want to do this in code behind using if loop.
I am having real trouble at the moment trying to input NULL values into a field. what I want is, using VB, the ability to insert into parameters NULL values.
View 3 RepliesI need to write a sql script which will scan for records in a table (Table1) and thencopy the records found into a second table (Table2). Table2 has the same table structureas Table1Table 1 has a primary Key for the first column named CustIdI thought this would involve A simple sql statement like:
INSERT INTO Table2
FROM Table1
SELECT *
However I just realized that if A record already exists in Table2 and I try to inserta duplicate record into Table2, how should this be handled?Should I instead use an Update statement without a where clause?
