Hey Luc,
I have a device connected in the USB port. I want to write data received from it to virtual com port. I want to do this in C#.
Is it possible and if yes can you please guide me through ?
Regards......

Hi,
you still did not clarify the situation. What is on the other side of the virtual port? Why do
you (think you) need a virtual port? Which virtual port are you referring to (i.e. who wrote
that driver, or how is it called)?
Anyway using a virtual COM port is identical to using a real serial port.

Hey,
I am a novice in this field. So I've no clue about virtual com port and the technicalities associated with it.
I have 2 questions that don't need any contextual information I suppose:
1. Can a virtual com port be created in C# ? If yes, how is it done ? And if no, then what is the alternate way to do it ?
2. If I have a virtual com port and all I need to do is write to it, then in that case is it possible to write to it using C#? How is it done ?
Please help me on this......
Regards......

I could not understand your comments.
For example:
I designed the interface in VS.NET 2008 with C # language include:
1 WebBrowser, 1 combobox control box to select ( ... appear in the WebBrowser control when I run the program.
But I do not know what events to use the box to combobox Select the object (HTML) in WebBrowser will be under control
I used events: Onchange but not successful
|
|
|
|
|
what are you going on about? makes little sense.
you want to know how to fire event when combo box value changes?
|
|
|
|
|
Yes!
Do you help me?Thanks

there are many events you can use for this.
but i think on selectedIndexChanged is the best for you.
you could also just create a 'Go' button to open pages, and that way you can free type url's in the combo box

No, you're mistaken. This guy has been asking this for days. He has a web browser control, inside that he has a drop list, in HTML, but he wants to catch the event in C#. Pretty bizarre if you ask me, but I'm sure he has a good reason for doing it this way. you gotta hope, at least.

I see...
Sounds a bit dodgey. Must mean they are not his webpages else he could code them to do the work, surely.
you plan on having this on other peoples machines?
|
|
|
|
|
See how he goes quiet ? he'll ask this again in a few days, I am sure.

Sounds like you're responding to an old question and that you're sufficiently lost that you think that the people doing your work for you, all talk to one another. Try either responding to the original answers, or reiterating the question, with what you've since tried.
I believe your core issue is that you are trying to catch events in a web form. This is not trivial, you can't just write event code because you can't hook C# to an event in a web browser.

Their design interface a Windows Form in which a dialog Combox and an object WebBrower.
You through dialog combobox on Windows Form to control the dialog box select the HTML on the WebBrowser to how?
Thank you

Hi,
hmm, sorry but I don't get your question... Do you want to select sth. in a combobox (URL etc.) that will change the URL of the WebBrowser?
If yes then add a SelectedIndexChanged-event to your combobox (double click in edit mode VS2008) and set the URL property of the webbroweser-control to the selected one in the generated event handler.
If this is not the solution, please rewrite your question in simple words (using e.g. numbers 1. click combox, 2. select url from combobox, 3. set url in webbrowser).

Sebastian

Is there a way to populate a combobox with a Dictionary please?
|
|
|
|
|
ComboBox class has Items property which allows to add items to it. You can iterate over the items in dictionary and add them to the combobox.
|
|
|
|

Hi,
I haven't done this, but I would try something like myComboBox.DataSource=myDictionary.Keys;

Hi,
I've string which contains valid XML (not as XML file), Is there any reliable way to parse that string by using XPath class.
Thanks in advance.
|

|
|

Hi,
what about using the xmlDocument and CreateNavigator to get XPathNavigation on that string?
<br />
XmlDocument xmlDoc = new XmlDocument();<br />
xmlDoc.LoadXml(sMyXmlString);<br />
XPathNavigator myNav = xmlDoc.CreateNavigator();<br />
Does this help you?
Regards
Sebastian

If you're using .Net 3.5, you can using System.XML.Linq; and use the XElement object to parse it.
