Is this correct:
public struct EMP
{
public string name;
public string surname;
}
....
EMP [] employee = new EMP[100];
....
Many thanks in advance

No, not yet ... but according to some code snippets I saw on the web it looks like it will work.
Thanks for the response.

Hi,
there is a difference:
in unmanaged C/C++ the struct EmpStruct has a size of 30 (or 32), since it contains 30
characters.
your C# struct has a size of 8 (or 16 on Win64) since it contains two references and
no characters.
So it all depends what you are trying to do:
- if you are porting a C/C++ app to C#, it could be good enough;
- if you want your C# to cooperate with existing software or hardware that needs the
original struct EmpStruct, then it is not OK, and you will need special Marshalling
instructions.

Thanks for the response Luc, well I'm rewriting a application into C# from C++ .... so that is the only reason I was asking.
Thanks again

the structs are value types and classes are reference types.

Hi,
We, in our office use a remote Matlab License server running FlexLM license manager. Since we have very few floating licenses we end up asking to release the license from the fellow engineers many times a day.This creates confusion as we are not knowing who is actually using the license.
To automate this I plan to make a simple application wherein I'll monitor the connection to that particular matlab server and see which user has actually hooked up a license if a socket to that server:port becomes alive. Then I would start broadcasting to the rest of the users that this user is using the License.
This can be achieved my making a service that would feed a frontend application with the broadcast details which would let people actually know who is using the license. It is a simple License viewer.
Since I don't have administrative access to the license server (it is organization wide server) so I just can monitor connections from my system or from a group of users who actually install the service I am planning to make.
My only concern now is since I am to use broadcast mode for letting others know I have hooked up a license I would be in trouble with network bandwidth.
Does anybody have a better architecture to prevent the broadcast and use some other tricky method.

Just curious. What's the cost of a couple new licenses versus the cost of you developing this application and supporting it for the same amount of time as you'll use the licenses??
You'd have to have some kind of central server that each client application would have to connect to. This server would probably keep track of the license use and notify the clients directly instead of broadcasting. So that's TWO applications you have to write, not one.

Well just to answer your First Question 4 Floating licenses of Matlab with only Simulink and Stateflow costs you around 8,200,000 INR which is equivalent to 206,861.4 US$. Hence a small application would be always better than procuring few more license.
Moreover getting approval for license and all needs a huge cycle time, against which developing an application would always be better

Hi,
I need help how I can convert the string below to ASCII(HEX)
for (int i = 0; i<=5; i++)
{
int counter = 0x0 + i;
string destinationAdress += (char)s[counter];
...
}
Thanks in advaced

What is all this?
0x0 is exactly the same as 0
o+i is exactly the same as i
you did not tell what s is
if s is a string, then s[counter] is a char and does not need a (char) cast
if s is an array of ints (just a guess), then you want some conversion from int to char. do you?
I think you better explain a bit more what it is you are after.

thanks I have found the solution. Explanation "s" is a byte array and 0x0 is the first element
int counter = 0x0 + i;
string Number = s[counter].ToString();
int number = int.Parse(Number);
destinationAdress += number.ToString("x2");

Hi,
your code has too many ToString/Parse calls. To convert a byte to an int, you don't need
these!
byte[] s = ...;
string destinationAdress = "";
for (int i = 0; i<6; i++) {
byte b = s[i];
destinationAdress += b.ToString("x2");
}

hello,
im running process from my gui in C#, its console application and id like to copy its output in seconds interval into clipboard. how can i send keys to that process to do something like i do manual (click on console menu - Edit - Select all - press ENTER). im trying this way because for specific reason RedirectStandardOutput and using stream doesnt work like it should (its copying just 80 characters width from console).
thank you

No. The only thing I ever did programmatically to a Console is set font colors.

You have to come up with a method to do this. If there was one method that everyone used, we'd all know how to defeat it, too. And, of course, anyone can decompile your app, remove your code and recompile it, anyhow.
One thing I will tell you is, don't rely on the date the app was first installed, the file system seems to mess with that, I've had trouble trying to use it in the past.
