there should be a bunch of examples online that will give you most if not all of the code you need. assuming that the value you want as the default is in the database, you just need to do dropDownList.SelectedValue = value; or you could use the SelectedIndex if you know exactly where the value will be in the data set and its location wont move. to bind the dropdownlist you just need to open an SqlConnection to the database set up a SqlCommand with your query and connection and use its ExecuteReader method to load a SqlDataReader which will then bind to a dropdown list like

sring sql = "";
SqlConnection myConnection = new SqlConnection(connectionString);
SqlCommad myCommand = null;
SqlDataReader myReader = null;

try{
myConnection.Open();
sql = "put your query here";
myCommand = new SqlCommand(sql, myConnection);
myReader = myCommand.ExectueReader();

dropDownList.DataSource = myReader;
dropDownList.DataTextField = "the field you want displayed";
dropDownList.DataValueField = "the value you want stored, like an id number"
dropDownList.DataBind();
//if you want to insert a value tat isnt in the database youjust need
dropDownList.Items.Insert(0,value);//i havnt used that ina while
//but is the locaiton in the array you want the item palces and value is the
//text to display
}catch(Exception e)
{
}
finally{
if(myCommand != null)myCommand.Dispose();
if(myReader !=null) myReader.Close();
myConnection.Close();
}

hope this helped

frame problem

I'm trying to use a repeater to display news articles with a link to each article or pdf or whatnot, however i dont really want the user to know that they've left one site to open one of the pdfs and i didnt really want to copy everything around since the news stories can be shown on multiple sites. so i have a javascript function that opens a new window to a htm page that has a frameset, then i try to se the location of the frameset in the same javascript like:

function newWindow(url)
{
var win;
win = window.open("news.htm","NewsArticle",
"toolbar=0,scrollbars=1,location=0,statusbar=0,menubar=0,resizable=1");
win.frmNews.location = url;
}

this works great on my machine, but it wont work when i put it on our web server, it says that frmNews in null or not an object.

that is the code from the news.htm file minus the title, meta tags, etc... the window opens but i cant change the link. any help would be greatly appreciated.

make sure that you don't have the javascript running on the server side

runat="client"

That's because the frameset hasn't yet loaded in the window.

Send the url as a parameter in the querystring to the frameset page, make the page asn aspx page, and user server code in it to get the url from the querystring and put it into the frame code.

Thanks, i got it working now, there was also a problem with the slashes in the url some were \\ instead of // and apparently js is rather perticular about it. i just used a loop to make the js wait until the frame was loaded then set its url, not necessarily good practice, but it works, and it completely hides the url i'm going to like it should.

It's rather the web server that is particular. If you use backslashes, it will not be treated as a separator between folders, but as a part of the filename.

So the url "http://www.site.com/folder\another\page.html" will try to get the file "folder\another\page.html" in the root folder of the web, not the "page.html" in some subfolder.

You have shown too little of your code to give any possibility to see any problem with it.

That code doesn't create any image. It just creates a string and returns it. That code has to go into a function to work, and you have to call the function and do something with the result in order for something to happen.

Try a fully qualified path to the password file. Something like;

AuthUserFile /XXXXXXX/XXXXXXX/htpasswd

By all means specify it in quotes.

I am learning here, I didn't know that you could run an Apache server on a windows machine.

I would love to do that. Please tell me how I can proceed.

PS - did specifying the full path help?
