2,328,449 | 2,328,450 | TextBox AutoComplete from MDB | <p>I have a .Net 4 Windows Forms app that uses a Microsoft Access Database with one table which has three columns CityCode, Name and Country.</p>
<p>What I want to do is have an autocomplete which shows the “Name” and “Country” but when selected the “CityCode” Value is shown in the textbox. In addition if the user types A City Code eg LAX as they type L it would list all the cities whose code or Name starts with L.</p>
<p>Can this be done?</p>
<p>Currently I have the following for access the database (but it seems to be a bit slow!)</p>
<pre><code>textBoxCity.AutoCompleteCustomSource = CityList();
public static AutoCompleteStringCollection CityList()
{
string connectionStringLD = string.Empty;
connectionStringLD = @"Driver={Microsoft Access Driver (*.mdb)};DBQ=c:\CityList.mdb";
string SQL = "SELECT CityCode from CityTable";
OdbcConnection conn = new OdbcConnection(connectionStringLD);
OdbcCommand cmd = new OdbcCommand(SQL);
cmd.Connection = conn;
conn.Open();
OdbcDataReader reader = cmd.ExecuteReader();
AutoCompleteStringCollection theCityList = new AutoCompleteStringCollection();
while (reader.Read())
{
theCityList.Add(reader.GetValue(0).ToString());
}
return theCityList;
}

3,500,497 | 3,500,498 | C# what is the size of unmanaged object? | <p>Read definition of <code>Marshal.SizeOf().</code> It says this: <code>The size returned is the size of the unmanaged object. The unmanaged and managed sizes of an object can differ.</code> Is that means Marshal.SizeOf will return you the definition size but not the actual memeory allocated size because there are may have some padding for alignment?</p>
<p>For example:</p>
<pre><code>struct MyStruct
{
char c;
}
</code></pre>
<p>The size will be 1 byte for unmanaged object (unmanaged size) if I use <code>Marshal.SizeOf()</code> but may be 2 or 4 bytes for managed object (managed size) if I use <code>sizeof(</code>). Am I right?</p>

5,465,216 | 5,465,217 | Allocating byte array to get 4 billion bits | <p>I was reading this book entitled, Cracking the Coding Interview by Laakman. There is this part where she (the author p.g. 202) did:</p>
<pre><code>byte[] bitfield = new byte [0xFFFFFFF/8];//there are 7 F's
</code></pre>
<p>She was allocating 4 billion bits. However, isn't 0xFFFFFFF = 2^28-1? Thus, she has only allocated a byte array of 2^28-1/8 bytes, which is not remotely close to 4 billion bits. It is only 2^28-1 bits. My question is- is she wrong or am I doing something wrong? How do we allocate 4 billion bits? I have tried:</p>
<pre><code>byte[] bitfield = new byte[0xfffffff *2];
</code></pre>
<p>Although the above causes the jvm to run out of heap space.</p>
<p>While we are at it, what is the best was to express hex values? e.g. 0xffffffff or 0xFFFFFFFF?</p>
