Re: How ENQ command is sent to serial port

Sorry I forgot to send the DataReceived event (which is on the form side) here is;

private void cardReader_DataReceived(byte[] b)
{
this.Invoke(new CardDataReceivedEventHandler(cardReader_DataReceivedInvoke), b);
}

private void cardReader_DataReceivedInvoke(byte[] b)
{
try
{
if (b.Length != 0)
{
string s = cardReader.BtyeArrayToStr(b);

}
}
catch (Exception ex)
{

}
}

Thanks for all the code, it does not really help; what one needs to design, implement and debug the
whole thing is documentation and a device for experimentation/verification.

You once more did not apply PRE tags (use the "CODE BLOCK" button below the edit field), so I am not going to even look at it.

And I forgot to tell you it is a very bad idea to catch an exception and then hardly do anything with it;
when things go wrong, the exception tells you the details of a problem, so let it show all it is holding
as in Console.WriteLine(exc.ToString())

Have you found the ASCII ENQ character yet?

Hello,

I have a default page on which there are three user controls put inside three panels within the page. Based on a click event of a button in any of the user control, i want to unload a user control in the page and load a diferent user control in its place. I am using VS 2008 and C# as the code behind... Your inputs would be very helpful....Thanks in advance

You can do it using delegates.

Create a delegate in the usercontrol with some return type / parameters with which you can set the visibility of the usercontrol, add an event for this delegate.
Add a button with a button click event in user ctrl.

Call the event in the webpage which in turn should call the user control's button click event.

Try this out.

Cheers,
Sudhanva

You could make the Set the Visible property on the controls to the appropriate value so they are not rendered to the client unless they need to be.

I would personally instantiate all of them with the Visible property set to false, and then show/hide them as necessary.

You can even initialize them when he VisibleChanged event is fired.

Thank you for the response. But here i am having around 50-60 controls now and the number is again going to increase. Do you think its a good idea to load as many number of controls on the form and keep its visible property false? The requirement is something as that of how Microsoft Dynamics work. We have one default page with left and main content panels that holds the user-controls which keep changing as per the button clicked...

Create new url type for RichTextBox [modified]

I want to create my own 'URL' in a RichTextBox. when a user types [[LinkName]], it should display as a link.

Example
The documents with name [[The road to C#]] and [[An introduction to C#]] are very interesting.

How can this be created in a C# RichTextBox and how can I add a ClickEvent.

Thanks!

You can do this by tweaking the registry, without lots of coding;

Hope this helps Smile | :)

In normal situation the thread execution ends when the method you passed for ThreadStart has finished.

You can call Sleep inside the thread. If you need to synchronize separate threads, see for example Join method and lock statement

If you know a type or have instantiated an object from the assembly you can get it's AssemblyQualifiedName, for example:

someObject.GetType().AssemblyQualifiedName

Is that what you were looking for?

yes but it dont have exactly what i want...i mean i have to parse that string to get the assembly name.

its format is like

Object's Full Name, Assembly Name, Version, Culture, PublicKeyToken

thanks

Re: get an assembly name

So do you need only the name? If so, if I remember correctly, you could use:

SomeObject.GetType().Assembly.ManifestModule.Name
