Pinging is no longer much help. Unless you turn on the File Sharing exception for Windows Firewall in XP SP2, or otherwise open port 445, Windows Firewall will reject ICMP Echo Request packets sent by ping, by default. You can enable them if required. You'll find that most other software firewalls will do the same.
If you need to determine whether you can connect to a network service, just try to connect to it. If you're trying to do a site survey you're probably out of luck.

What is the best way to create one in C#?
I guess I need to create a tuple class or is there something like SortedList for tuples?

what do you mean by tuple, can you give an example? If you mean a variable that holds two values, you can easily use a struct or class

Well, I am experimenting with this right now
<br />
class Tuple<br />
{<br />
private string relationship;<br />
private string phrase1;<br />
private string phrase2;<br />
<br />
public string Relationship<br />
{<br />
get { return relationship; }<br />
set { relationship = value; }<br />
}<br />
public string Phrase1<br />
{<br />
get { return phrase1; }<br />
set { phrase1 = value; }<br />
}<br />
public int Phrase2<br />
{<br />
get { return phrase2; }<br />
set { phrase2 = value; }<br />
}<br />
}<br />
I might change it to objects instead of strings. I just need something that will be fast for searching and sorting it's data. SortedList works great but that is only for a (key,value) not (key, value, value).

That's okay. The easiest way is to implement IComparable in your Tuple class. The SortedList will then sort your keys according to the result of the CompareTo function of your Tuple class.

Thanks. I'll play around with that idea.

Outstanding. Thanks.

Actually, I just discovered that there are Pair and Triplet classes of Objects in .NET 1.1 but they're in System.Web.UI. Surprised they didn't update them to generic versions and put them in the generics namespace. However, I expect they'll roll in some of the PowerCollections stuff over time.

Has anybody ever drawn the red squigly lines that show up say in Word or other apps under a word when it is misspelled?
I have come up with a way but it is not reliable to underline all words. My method gets messed up with tab chars and also hidden text. I suspect the same would be true for tables and inserted pictures.
Thanks in advance,
Eric

From my knowledge, it is not directly possible to use the rtb class to draw the Office-Style underlines.
However, you can have an effective selection method by saving the selected text and creating custom functions to get text from it - even with hidden text
|
|
|
|
|
I think you would probably have to directly draw the lines on the control, either using RichTextBox.CreateGraphis() or by creating a class that inherits from RichTextBox, and overriding RichtextBox.OnPaint
|
|
|
|
|
Its possible to draw the line using the approach mentioned. However, the difficulty I'm having is reliably calculating the coordinates of the beginning of the word that needs to be marked with the squiggly.
Any suggestions there?
Thanks again,
Eric

Use the GetPositionFromCharIndex method.

Will u please post the code!!!!!!!!

Hi!
The Rich Edit control that's actually the core control underneath the RichTextBox can display underlines (even the squiggly ones), but setting the corresponding character styles is not possible directly with the regular RichTextBox.
You'll have to send EM_SETCHARFORMAT messages to the rtb to enable underlining in a given style. You can't have an underline color that's different from the text foreground color, though.
You might want to look up the CHARFORMAT2 structure in the Platform SDK documentation on the different options you have to underline text within a rich edit control (and thus in a RichTextBox).
Regards,
mav

Just found out that my statement on the underline color was incorrect.
You CAN have different underline colors, althouth it's not documented in the CHARFORMAT2 struct. The upper 4 bits of the bUnderlineType determine the color.

Hi everyone!!!
I want to add SplashScreen to my application. I found on the Web a source to do : http://www.reflectionit.nl/Splash.aspx
To give more promptness to this SplashScreen, I have to add a Flash 8 control (OCX Flash). There I have problem on execution. The error message :
Impossible to reach a removed object named "SplashForm"
Is there solution!!!
Thank you!!!

Try making a new project, and copying all your existing source into it

Hi James Gupta and thanx for reply !!!
That what I have done, but there is always same problem !!!
I don't know if you you've seen the code source of the application (URL : http://www.reflectionit.nl/Splash.aspx). The problem is only when I add a Flash OCX control (Flash8.ocx) to the SplashForm  , else, I have not this problem.
Thanx!!!

Hello, does anyone know how to use DrawString / DoubleBuffer / UserPaint / AllPaintingInWmPaint to paint your own RichTextBox? This is for a news ticker that contains multiple fonts, font colors and embedded images. The autoscrolling is working great, but the flicker is really bad and I was told that double buffering is the way to go (is it, or is there something else, like making an image and double buffering its movement??). Any pointers would be really appreciated!

You could override the RichTextBox class, and in the constructor:
<br />
this.SetStyle(ControlStyles.OptimizedDoubleBuffer, true);<br />
this.SetStyle(ControlStyles.AllPaintingInWmPaint, true);<br />

Is it possible to fire two events at the same time?
In my code I fire off an event if my if statement is true (see code below)
<br />
if (SegType == "Y")if(OnQResponse != null) OnQResponse(this, new EventArgs());<br />
Could I add the other event in this statement? Like: if(SegType == "Y") if(OnQResponse != null && OnDataRecvd != null){OnQResponse(this, new EventArg()); OnDataRecvd(this, new EventArg());
Thanks

The only problem I see is your approach, if one of the 2 handlers is null, no event is fired. But that may be the intended behavior. If this is the case, that may confuse other parts of the application expecting to be notified of one event, but are not because nobody subscribed to the other one.
If this is the intended behavior, simply make one event: OnQResponseAndDataRecvd.
if ((segType == "Y") && (OnQResponseAndDataRecvd != null))
{
OnQResponseAndDataRecvd(this, EventArgs.Empty);
}
If you need 2 separate events:
if (segType == "Y")
{
if (OnQResponse != null) OnQResponse(this, EventArgs.Empty);
if (OnDataRecvd != null) OnDataRecvd(this, EventArgs.Empty);
}
You may also notice the use of EventArgs.Empty instead of new EventArgs(). Basically, EventArgs is a class that contains no information, and this way you avoid creating unnecessary new objects.

If you mean that the code handling the two events should execute at the same time, then no.
An event is basically a list of method pointers. When you call the event, it will just call the methods in the list one after the other. That means that when you call OnQResponse, it will not return until all event handlers in it has been executed.
