Bellow is the PopulateListBox() function in VB it goes through every row in the data set and see if it is deleted, not deleted or has errors. I am getting 2 errors here both on the lines
lstAlbums.Items.Add(item);
and
lstAlbums.Items.Add(delitem);
now i realise that the strings are unassigned so i added
string item = "";
string delitem = "";</p>
<p>then when i start the program it fills every second item in th list box with a blank row.</p>
<p>How do i overcome this situation? thank you in advance anyone how can help me. </p>
<pre><code> private void PopulateListBox()
{
string item;
string delitem;
//clear the list box
lstAlbums.Items.Clear();
//access each row in the data set table
foreach (DataRow row in myDataSet.Tables["albums"].Rows)
{
//list the nondeleted rows

item = row["albumCode"] + ", " + row["AlbumTitle"] + ", " + row["ArtistCode"];
//list rows with update errors

5,260,738 | 5,260,739 | Javascript position two elements on top of each other | <p>I have two divs one above the other. The second on is absolutely positioned below it (an absolute div inside a relative div).</p>
<p>I want to move the second div on top of the other div, so it appears in the middle.</p>
<p>The procedure for this is to set the style.top of DIV2 to be the same as DIV1, this should in theory position it on top of it. However so far attempts have failed.</p>
<p>The absolute positioning is working correctly, because putting in values moves it correctly, but I think I am using the wrong way to get the height/top values of DIV1.</p>
<p>Ideas?</p>
<p>I tried this:</p>
<p>divLoading.style.top = divContent.style.top;</p>
<p>but it stays where it was.</p>
<p>Edit: The problem isn't how absolute/relative works but which javascript values are the correct ones to use. Using DIV2.style.top = DIV2.style.top - DIV1.clientHeight moves it to the top... but clientHeight is not correct, because if DIV1 changes size, it moves DIV2 way too far upwards.</p>
<p>Edit: offsetTop seems to be zero.</p>

<li>List GetClients()</li>
<li>Client GetClientInfo(int clientId)
In the above methods, the return value/object for each method corresponds to the "all good" scenario i.e. A client Id will be returned if AddClient was successful or a List<> of Client objects will be returned by GetClients. But what if an error occurs, how do I convey the error message to the caller?</li>
</ul>
<p>I was thinking of having a Response class:
Response { StatusCode, StatusMessage, Details }

<p>when the user clicks on a item in the searchresults now, the inputfield fires the focusout event as desired.
i expected to be able extracting the element which gets the focus as next out of the eventobject. unfortunatly this seems not to be possible since only (some) mouse-events fill in the relatedTarget-property of the event.</p>
<p>is there any easy way to get the element which gains focus next?</p>

2,658,799 | 2,658,800 | How to convert MVS C++ code into executable application? | <p>So I've made a small program in Microsoft Visual Studio C++ (2008 edition) and I want to convert it to .exe format.</p>
<p>I know that I can find the .exe in my project directory, however it only runs fine on my own PC. When I send it over to someone else (who doesn't have Visual Studio installed or anything), it doesn't run.</p>
<p>I've read a little about this and it seems to be about "linking". Now I don't know anything about linking and I'm not eager to learn in depth about it right now...</p>
<p>I just want to make my incredibly simple program (which edits and creates text files) to run in .exe program on any computer. Is this possible, and if so - how?</p>
<p>Could you please guide me through the steps? I'm quite new to programming so I really need help on this one.</p>
<p>Thank you in advance...</p>
