You can use DeflateStream [^] to compress the incoming stream.

Parameter count mismatch in multi-threading

I am getting the following error message: "Parameter count mismatch" I get this message when I run my program using Task for multi-threading, however when I run without multi-processing I do not get an error.

The process runs fine and to completion without a problem, but after it is finished this error message pops up. If it is a parameter count mismatch why does it not show up in as an error when I build the project. Why doesn't it show an error when the variables are transferred at the point in the process.

How do I find the problem, what are the possible reasons for this problem.

Any help will be appreciated, thanks in advance.
Michael

You won't get much help if you can't be bothered to post the offending code.

As said before, almost impossible to figure out what your problem is. I would suggest that, if you don't already, depend on a single object to pass information instead of multiple objects. That might help.

Since the error comes up with multi-threading only, I'd think it is the block of code where you create and start the threads: do you provide enough parameters for the methods to be started in different threads, and also not too many parameters?

Prefix vs. Postfix Increments

I've noticed I've been using a lot of prefix incrementors in code lately (esp. for counters), simple e.g.:

int counter = 0;
foreach (var thing in things) {
   thingThatCares.TellMeWhereIAm(++counter);
}

I typically don't see a lot of prefix operands in other folks' code, so I'm wondering if there's a better way of doing things like that, or it's just stylistic, etc.?

It is better and faster then postfix when you do not need the original value. Although, most modern compilers would optimise a postfix expression for the same reason.

There should be no difference except that one happens after the operation, the other before. However, in a for loop it does not matter:

for (int i = 0; i < 3; ++i)
    Console.Write(i);

for (int i = 0; i < 3; i++)
    Console.Write(i);

Yields the same result. However these do not:

for (int i = 0; i < 3;)
    Console.WriteLine(i++);

for (int i = 0; i < 3;)
    Console.WriteLine(++i);

You need to use the ShowDialog() method:

Form2 form2 = new Form2();
form2.ShowDialog();

Hope this helps.

Console Check (Part II)

It's a real pain in the ass to overwrite the previous console line when the next line written could be smaller and the previous one may not all fit in the console (window or buffer) width. For now, I'll have to mark my dummy writes with a special character. Sigh | :sigh:

You should be posting this in the original thread, not starting a new one. I, and many other people, have no idea what you're talking about.

DO NOT post stuff like this as a seperate thread. Post it on the orignal thread so people have a clue about what you're talking about. All you're doing is cluttering up the forum with posts that don't make sense.
