Once "IsMature", and "CanReproduce", it "BeginReproduction"s, but it never (or almost never) gets the reproductionComplete event.  Are there activities which stop reproduction and/or incubation   Is it just a certain energy state&nb ...Show All

  I have an ready-made application which saves which saves all times in GMT format in the SQL Server and i need to get the time in my application in my time.. for example, if a call made on 15:30:25 it will be save in the database as 12:30:25 but i need to read it again as 15:30:25.

  I am using Visual J# 2005 Express Beta 2 to create a simple echo server. I have created the form and design and able am able to launch the program. I have created a RichTextbox to display the connections and 'echo's. The problem is when after starting the echo server by clicking on a button, the program stops responding. But the echo server is running in the background because I am able to connect to the echo server (localhost/port with telnet) and am able to "echo" messages.

• Smart Device Development Drawing Graphic Images using .NET CF 2.0

  If I have an EMF (vector) image in a memory stream and want to overlay it on top of a bitmap what alternative do I have besides ImageAttributes   Using the SetColorKey method doesn't appear to work because I don't know the pixel location or shape of the vector image beforehand.  Is there a way to do this in a Pocket PC 2003 application without having to resort to unmanaged native C++ (CDC, CompatibleBitmap, HBitmap, etc.) .NETCF does not have support for EMF images. You will likely need to resort to native code to render the image into a bitmap and then (in managed code if you like) overlay that b ...Show All
