Eclipse: Speeding Up

Increase the amount of heap memory allocated to Eclipse to speed up execution when developing and debugging large applications.
To allocate 256MB, change the command line to launch Eclipse as follows:

C:\eclipse\eclipse.exe -vmargs -Xmx256M

Eclipse: Access restriction: The type x is not accessible due to restriction on required library C:\Program Files\Java\jre6\lib\rt.jar

To resolve this problem go to project properties. Under Java Compiler>Errors/Warnings
Under "Deprecated and restricted API" change "Forbidden reference (access rules)" to "Ignore"

C#: Copying 2 buffers

Use Buffer.BlockCopy method

<span style="color:Blue;">public</span> <span style="color:Blue;">static</span> <span style="color:Blue;">void</span> BlockCopy(
	Array src,
	<span style="color:Blue;">int</span> srcOffset,
	Array dst,
	<span style="color:Blue;">int</span> dstOffset,
	<span style="color:Blue;">int</span> count
)

byte[] dataRcvd = new byte[20];
byte[] commBuffer = new byte[5];
Buffer.BlockCopy(commBuffer,0, this.dataRcvd,0, 5);
