I'm not sure exactly but you might take a look at
"SELECT * FROM myTable where Professions = 'ListBox2.Items(i).Text' "
shouldn't these be something like
"SELECT * FROM myTable where Professions = '" + ListBox2.Items(i).Text + "' "

(I used string concatenation from c# I'm not so good with VB Smile | :)

)

Tell me if it worked... Smile | :)

That mistake was already spotted when I last post a message a day ago but I forgot to change it when I paste the code in the message box. Unfortunately thats not the problem but thanks for your help. This call is made in the page load and in the button1_click sections of the code behind. The listbox is in multi-select mode.

I am trying to read blobs from a field in a database table. The blobs hold resumes and each resume can have one or many corresponding professions in the Professions field. I am trying to enable users to look up resumes forcertain professions by choosing one or many professions in the listbox. The Select statement selects my table where the text of the listitem chosen by the users match the profession in the Professions field.

Imran Khan Pathan is right... I didn't see it the first time but you are doing something like these

You have a "for" that walks through the listBox2 elements and sees which is selected...then you make a query in the database (inside that "for") and you bind the result of the query with the same listBox2...these alters the containt of the listBox2 and the for is not working anymore (ListBox2.Items.Count is not the same after you have done the binding in the "for" statement and also the ListBox2.Items are changed)

Just call me Valy... Smile | :)

You are changing the items of the list box while you are looping through the items.

I've used the for loop to determine the list item selected by the user. Then I used the select statement to select the profession that is equal to the text of the list item that was selected. If I change the contents of listbox2 during each iteration of the loop when I bind the data to listbox2, then does that mean I can't use the for loop like I did? Should I bind the data out side of the for loop? I'm going to try and change the sequence of my code, but please give me some suggestions on how to remedy this code.

Take datalist in div tag and apply style="display:none;"

Javascript function

function visibility(divId)
{
if(document.GetElementById('divId').style.display=="none")
document.GetElementById('divId').style.display="block"
else
document.GetElementById('divId').style.display="none"
}
