Hey all,

I am looking for a managed .NET MODBUS component. Anyone know of one. Everything I have found is ActiveX or C++ dlls. I can go with one of these, but would like to avoid it if possible.

Thanks in advance.

The .NET framework isn't designed to do low-level stuff like limiting the number of packets that can come in via TCP.

You probably *could* do this in C#, however, you'd just be making a bunch of Win32 calls via P/Invoke. And in that case, it may be better to use the right tool for the job, which would be C/C++.

There are some articles on CP that deal with low level TCP, packet sniffing, etc. here[^], for example.

.NET Framework 1.1 and List Class?

Hello,

There is no List class attributes, if I use 1.1 version of .NET framework.
Thank you.

Well, yes there is no List object in the .Net Framework 1.1. Do you have a question? Smile | :)

There are plenty of objects that implement IList that will behave like a list. Pick the one that is appropriate for your needs.

The question was if there is a List class, in 1.1 version.
I pretty much answered my own question.

Thank you.

Hello there,
i am developing a custom TabControl.
Have you seen the standard TabControl? From the properties window one can add or remove tabs...

I want to do the same!

Do you know guys if there is a way to achieve my goal? D'Oh! | :doh:

I think these are called verbs. You can also see them by right-clicking on the control in the design window.

You will need to do some reading on Designers. I would tell you more but I've never used them myself.

[serializable] trouble

Sasuko24-Oct-05 2:46

i've used this stuff more and more times in the same project of my application.
Now i've saved a file and i've tryed to open it with another my application that has another namespace.
Now i can't open it.
How can do a free-namespace serializable class?

Re: [serializable] trouble

You mean namespace-free, I reckon.

When you serialize an instance of a class, the serialized data is intended to reconstruct an instance of that class, not some other class that happens to have the same name.

Why don't both of the apps use the same namespace and the same class? In other words, maybe you should have a separate library which both apps (the one saving and the one loading) use.

Either that, or you shouldn't be using serialization for this purpose. From what you are saying, it sounds like you may be abusing the idea of serialization and now it is coming back to bite you. Wink | ;)

try - catch problems

Hello,

I have a recursive function call, and I want to cathc the StackOverflowException, in case too many stamps of the function are created. Here is my code to catch the exception:

<br />
public decimal startCalculationOfIRR (double[] intArray, decimal rate)<br />
{<br />
 .<br />
 .<br />
 .<br />
<br />
<br />
try {<br />
	                 rate = this.calcIRR(intArray, MINRATE, MAXRATE, rate, prevTotal, increment, counter);<br />
	              } catch (StackOverflowException) {<br />
	                 return -0.00m;<br />
	              }<br />
 return rate;<br />
}<br />
<br />
<br />
public decimal calcIRR (double[] intArray, string MINRATE, string MAXRATE, decimal rate, double prevTotal, decimal increment, int counter)<br />
{<br />
 .<br />
 .<br />
 .<br />
<br />
 return calcIRR (intArray, MINRATE, MAXRATE, rate, total, increment, counter);<br />
<br />
}<br />
<br />

The problem is that the try catch statement does not seem to catch the error, since the program exists with the StackOverflow Exception. Any ideas?

Thank you

hi,

catch the exception in the method calcIRR (intArray, MINRATE, MAXRATE, rate, total, increment, counter)

just try this.

i hope this should work for u

Regards,

Pramod

Catching the exception within the calcIRR function does not work either.
I just don't know what's going on.

Thanks

Re: try - catch problems

AB777124-Oct-05 3:35

then try and use the base Exception class instead of
StackOverFlowException

May be this works

Thanks

I already tried to use

catch (Exception), but to no avail. It seems nothing works. It's almost like there is no catch statement at all present.

Thanks

You really shouldn't be coding like this. When a stack overflow exception occurs, there is no guarantee that any additional code will execute, like catch or finally handlers, for example.

You are much better off using iteration instead of recursion.

WIth iteration I have to know basically the number of iteration I must perform. Unfortunately here I don't know that. That is why I used the recursive call.

Thank you.
