Reposting is considered rude - please don't do it, it was only 17 hours ago you asked the same question which I have just responded to.

It's a bit of an odd scenario since real serial ports don't tend to disappear, and it doesn't seem this possibility was taken into account when Microsoft wrote the SerialPort class: There's no event that indicates Com-port "disappearance" in it.
I guess your best option would be to start a separate thread that polls SerialPort.IsOpen every now and then: Most likely this will throw the error you got earlier when you disconnect the USB adapter, so you can catch that to see if the port's still there... Of course, you'll need to catch it at any other reference to SerialPort as well, that's just decent programming.
Alternatively, there might be a class somewhere in the .Net framework that monitors USB devices, don't have any experience with that. Could very well be a p/invoke kind of thing.
Standards are great! Everybody should have one!

Hi bankey,
"=" can't be overloaded in C#.
For your information other oerators like, . , ?:, ->, new, is, as, sizeof too can't be overloaded.

Panicker.
P.S. Mark as answer if you feel the reply is appropriate.

Hi,
you can implement implicit conversions though, so that may or may not solve your problem.
look for the implicit keyword.

Wrap the particular application up in a CCW. (Com Callable Wrapper).
|
|
|
|

Could you please tell me a bit in detail? Which application you want me to wrap?
A guidance to some kind of example will be very nice. Thanks for a reply.

Hi,
Is there any control in C# , In which we can load rtf wtih header and footer and do margin setting as well.
If you have any idea about this, then please inform me at

You can use richtextbox to load rtf files but I'm not sure whether you will be able to manipulate with margin settings. You could give it a try though. I guess you can achieve what you want using this article: Integrating Microsoft Word in your .NET applications[^]

I am trying to write code for compiler using Codedom. I am unable to compile code which uses COM references. The code gives file not found exeception while adding COM reference to Compiler parameter object even if it is present in the output folder of the code to compile(No idea why).
The possible solution I can search of is to get the executable path for the code to compile because those dlls are present in the same folder(I may be wrong here).
How can I get the executable path of the code that will be compiled??
or
Am I going with wrong approach?? If yes, then how to solve this issue????

Did you generate the assembly you are adding with 'tlbimp'. You can't add a direct reference to a COM library.

How can I have a delegate or button continue an ongoing process that was stoped. And how do pause a process at a set interval(see below).
for (int i=1; i<=10000; i++)
{
for (int j=1; j<=10; j++)
{
a = a + 1;
}
//Pause process here everytime
//Continue process with button is pressed
}
Thanks in advance

Are you not able to implement with timers or Thrading ?

MessageBox.Show is going to stop the process and it will restart when you close the box.

I already considered sleep, but this won't work I have a timer that needs to start the process at set intervals using a delegate.

so then you should use MessageBox as Christian Graus said
or use timer_tick event intead of for loop
TVMU^P[[IGIOQHG^JSH`A#@`RFJ\c^JPL>;"[,*/|+&WLEZGc`AFXc!L
%^]*IRXD#@GKCQ`R\^SF_WcHbORY87??6?N8?BcRAV\Z^&SU~%CSWQ@#2

Given:
a textBox1 with a key event
typing in a string and a unicode(i.e letter "a with circumflex") to be inserted whenever a letter "a" is pressed
problem:
after it inserting the letter, it added an extra "a" at the front
and the cursor does not stay at inserted-position. It start at the front
instead.
Expect to be:
get rid of the extra letter and move the keep the cursor at where it perform the inserting process.
I used the remove() but didn't work
my code is as follow. Please help me.
private void keyDown(object sender, System.Windows.Forms.KeyEventArgs e)
{
int curPos = textBox1.SelectionStart;
if(e.KeyValue.ToString()=="65")
{ char[] unicode = {'\u00E2'};
textBox1.Text = textBox1.Text.Insert(cur,new string(unicode));
}
}
