The <code>ParseExact</code> method returns a <code>DateTime</code> value, not a string. If you assign it to a string variable you will be converting it automatically, which uses the standard formatting.

If you want it in a specific format, then format the <code>DateTime</code> value as a string:

<pre><code>Dim d As DateTime = DateTime.ParseExact(theTime,"HHmm", Nothing);
Dim convertedTime As String = d.ToString("hh:mm tt")
</code></pre>

There are two ways to achieve this.

Option 1 (using <a href="http://msdn.microsoft.com/en-us/library/az4se3k1.aspx#ShortTime" rel="nofollow">standard date and time format strings</a>):

<pre><code>Dim theTime As DateTime = new DateTime(2008, 4, 10, 6, 30, 0)
Dim convertedTime As String = 
 theTime.ToString("t", CultureInfo.CreateSpecificCulture("en-us"))
</code></pre>

Option 2 (using <a href="http://msdn.microsoft.com/en-us/library/8kb3ddd4.aspx" rel="nofollow">custom date and time format strings</a>):

<pre><code>Dim theTime As DateTime = new DateTime(2008, 4, 10, 6, 30, 0)
Dim convertedTime As String = theTime.ToString("hh:mm tt")
</code></pre>

In both cases <code>convertedTime</code> will be <code>6:30 AM</code>

</code></pre>
You Will Get The Formatted Timings In Any Label In Both VB.NET And C#

So let's say I have 1400, I want to convert it into 2:00PM

I tried the following:

<pre><code>Dim convertedTime As String = DateTime.ParseExact(theTime,"HHmm", Nothing)
</code></pre>

And it would give me this:

<blockquote>
 6/12/2012 02:00:00 PM
</blockquote>

I do not want the date part, neither do I need the seconds. All I need is 2:00PM

How could I achieve this? Thanks!
