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

we meet again!
did you ever try with ProcessStartInfo.CreateNoWindow=true?

hello mr. yeah i tried all combinations of that process.startinfo but wasnt successful and i was speaking to one guy that also had this problem and he didnt find solution cause its probably some problem with cygwin applications. so im trying this way. do you know how i could copy it from console?

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.

Good Day,
When I want to read a file as byte[] in the past, I always use this code:
byte[] Bytes = File.ReadAllBytes(FilePath);
The problem with the above code is it consumes too much memory (I think ) and I can't inform the user of the progress of the file reading.
Is there a better way of reading binary files in such a way that I can get the progress of the reading?
Thanks!

Only if your file is huge

True

Do it the old way, open the file, create a byte array and read a section at a time, but you'll need to do it on a thread or use Application.DoEvents for your UI to update during the process.

Thanks for the reply Mr. Graus.

I usually read 500mb to 1gb of data.

Yes, I'll be using a Background Worker for this.
But can please point me to an article on how do it the "old way" using buffers, loops and stuff.
Thank you.

Well, I hope your users have 2+ gig of RAM and a lot of time then....

Thanks.
Using the given method on the bottom of the page, I can successfully read a file. But somehow, reading a file that is too large (350mb) gives me an Out of Memory exception.
Is this a problem with the code?
public static byte[] ReadFully (Stream stream, int initialLength)<br />
{<br />
if (initialLength < 1)<br />
{<br />
initialLength = 32768;<br />
}<br />
<br />
byte[] buffer = new byte[initialLength];<br />
int read=0;<br />
<br />
int chunk;<br />
while ( (chunk = stream.Read(buffer, read, buffer.Length-read)) > 0)<br />
{<br />
read += chunk;<br />
<br />
if (read == buffer.Length)<br />
{<br />
int nextByte = stream.ReadByte();<br />
<br />
if (nextByte==-1)<br />
{<br />
return buffer;<br />
}<br />
<br />
byte[] newBuffer = new byte[buffer.Length*2];<br />
Array.Copy(buffer, newBuffer, buffer.Length);<br />
newBuffer[read]=(byte)nextByte;<br />
buffer = newBuffer;<br />
read++;<br />
}<br />
}<br />
byte[] ret = new byte[read];<br />
Array.Copy(buffer, ret, read);<br />
return ret;<br />
}
It is said that the most complex structures built by mankind are software systems. This is not generally appreciated because most people cannot see them. Maybe that's a good thing because if we saw them as buildings, we'd deem many of them unsafe.

Hi,
One of our windows application developed in C#.Net (Visual studio 2005) requires the functionality of
converting .pdf or .doc files to .html file format.
(without lossing the original format in the .pdf or .doc file). We have tried few third party tools, but none of these can keep the same format of the source files. Can anybody help me?Also please suggest few .dotnet supported tools for this conversion.
Thanks in advance
