Re: Write/Read ISBN of a book in NXP tag and Turn security ON/OFF

You expect people to root around in an SDK without even a hint of who the vendor is?

Did you even bother to unzip it?

I really don't understand, why you are telling this. Vendor is, Feig. It's a german company.

You can write an "ID" to the device; that would be your ISBN, I presume.

You can toggle various bits; the "security" would depend on what checks those bits.

There is a "write ID" command; whether it meets your requirements is for you to determine.

I suspect you are probably more interested in reading and writing to the device's "user area".

The "user area" depends on the device type (again, your domain); e.g. (from the link I sent).

Chip ID: 1h = 00000001b (Bit 47 - 40 of UID) 
Memory organization: 32 x 4 Byte = 1kBit 
Number of blocks 32 (user area: 0 – 27) 
Block size 4 byte

0x23 Read Multiple Blocks 
0x24 Write Multiple Blocks<br />

So; crack open the SDK and refer to "reading and writing" from / to the "user area".

How would you make a computer generate a response based on a question asked. and how would this be generated

I'd get the computer to email the question to a human being and post his response...

Sorry, but that's far, far too broad a question for us to answer!
What have you tried?
Where are you stuck?
What help do you need?

Bad command or file name. Bad, bad command! Sit! Stay! Staaaay...

Get hold of a suitable natural query engine/interface for whatever it is you are trying to do.

Trigger my application using Ctrl+F

Just generate a random answer.

Sort of like the "Magic 8-Ball" ...

Question: "Will I be happy?"

Answer: "Outlook good".

Hello,
I am new to C#. I have an application which has easy interface for File search. I want to trigger that application using Ctrl+F only when Windows Explorer is active.

Is it possible in .net ?
Is there any available example codes ?
Please help.

You need to add a windows keyboard hook:

not working input simulator

2-Apr-16 5:11

No code ... no help.

Suggest you review one of the many samples that comes with DevExpress; focusing on "tool bars".

Or just focus on a non-DevExpress tool bar; if it makes no difference. Will probably get more help that way.

how to fix that error in visual studio 2013 i use inputsimulator but it gave me an error
s.get_Keyboard().ModifiedKeyStroke((VirtualKeyCode) 17, (VirtualKeyCode) 68);
it show me an error no virtualkeycode

Error	2	'WindowsInput.InputSimulator.Keyboard.get': cannot explicitly call operator or accessor

Properties are accessed with the same syntax as fields:

s.Keyboard.ModifiedKeyStroke((VirtualKeyCode) 17, (VirtualKeyCode) 68);

There actually are methods for getting and setting but the C# compiler doesn't allow you to explicitly use them.

Just as an info-tidbit: You would be able to call these methods via reflection.

You didn't copy my corrected code. Take another look.
