Hello.
If a function like OnMouseMove is implemented in a derived class, without any message map info, this function gets called when the event occurs. How is the housekeeping done on this? One would think there is an overhead of calling all the event functions irrespective of wether it is implemented or not. Or is an optimization done at compile time?
Any useful links or explanations on this would be helpful.
Thanks in advance.
Regards,
Priyesh

Event handlers are basically a linkedlist of function pointers. The standard implementation will check whether the event handler is null, otherwise it will invoke each function pointer (delegate) in the eventhandler.

Does this mean that delegates and Onxxx functions use the same mechanism to deliver events?

Hello,
I've set up a site for my company which pulls content links from the database and binds them to a repeater which produces a list of linkbuttons with the text and link to the appropriate story. However, a great deal of importance has been attached to search engine placement and the ability of spiders to travel unimpeded throughout the site. Since a linkbutton does not produce a conventional url which can be followed by a spider, is there any piece of data that a linkbutton can produce allowing a spider to travel to the displayed link?
Thanks for any help you can provide.

I have a question abount Socket Communication.
When Socket Connection was founded with Server and Client,Cliet send information to Server.Whether string array can be sent to Server.In the other hand,Whether object can be sent to Server.
When Server received the information,whether it can be convert to Array,or other object.

Objects have to be serializable (take a look at SerializableAttribute).
Arrays are serializable, if the elements are serializable.
You can send a serializable object/array through a socket by BinaryFormatter.Serialize(). The other side can read it by BinaryFormatter.Deserialize().

I am trying to convert a routine from C to C#, that will scan over a character array converting the 1st character of every word to upper case. I mainly use this on peoples names.
In C it was very simple, I just loop over the characters and "AND"ed the byte with 0x20. In C# it wouldn't let me do that with strings, saying it was read only, so I tried copying it to a byte array, which kinda works.
I removed the 1st letter of each word logic to simplify the code. Now the code reads:
byte[] strout = new byte[255];
string workstr;
workstr = textBox1.Text;
for (int i = 0; i<textbox1.text.length; i++)
{
="" if="" (textbox1.text[i]=""> 0x60)
strout[i] = Convert.ToByte(workstr[i] & 0x20);
else
strout[i] = Convert.ToByte(workstr[i]);
}
textBox1.Text = Convert.ToString(strout);
What I am getting when trying to "AND" the 0x20 is just 0x20, it doesn't just turn off the bit. Also how do you convert the byte array back to a string? I have tried a couple of convert methods but haven't had much luck.
Thanks,
Glenn

When I pasted in the code the for loop got chopped off...its actually like this:
byte[] strout = new byte[255];
string workstr;
workstr = textBox1.Text;
for (int i = 0; i<workstr.length; i++)
{
="" if="" (textbox1.text[i]=""> 0x60)
strout[i] = Convert.ToByte(workstr[i] & 0x20);
else
strout[i] = Convert.ToByte(workstr[i]);
}
textBox1.Text = Convert.ToString(strout);

Firstly, you can still do this with C# - convert the string to a char[] array using String.ToCharArray(), AND each char that needs it, then convert the char array back to a string using new String(chararray). (It's not byte because .NET uses Unicode.)
Secondly, the AND 0x20 isn't needed, as you can use Char.ToUpper().

The simplest solution is to treat the string as a character array instead of a byte array. Here is a simple function that you can pass your line of text to. It simply looks to see if the current character is the first character in the array or if the previous character is a space and capitalizes the character accordingly.
string formatString(string input)
{
char[] result = input.ToCharArray();
for(int i=0; i <= result.Length; i++)
{
if ((i==0) || (result[i-1]==' '))
result[i] = char.ToUpper(result[i]);
}
return new string(result);
}

The i <= input.Length should be i < input.Length.
0 Based.

I have a string value in the registry that i'm trying to read into my app. I need this value to be read as an integer so i can use it in a custom function.
<br />
RegistryKey rk = Registry.Users;<br />
rk = rk.OpenSubKey(@".DEFAULT\CustomForm", false);<br />
int result = calculate(rk.GetValue("GRN1"),2);<br />
<br />
public int calculate(int x, int y)<br />
{<br />
int result = x * y;<br />
return result;<br />
}<br />
The rk.GetValue("GRN1") returns an Object Type, but how can i get it to return an Integer type. I get an 'Invalid Cast' error when i try to cast from a different 'domain' (as msdn calls it)....
int result = calculate((int)rk.GetValue("GRN1"),2);
so, how can i get an object value from the registry to convert to an integer?
Thanks for your help

Have you tried: Int32.Parse(rk.GetValue("GRN1"),2); ?
That might work.

Convert.ToInt32(rk.GetValue("GRN1")) should do the trick.

Hi, is there a way to turn rtf text into html? i.e. bold to <bold>
|
|
|
|
|
even bold to <b>bold</b>
tia
|
|
|
|
|
Try this:
richTextBox1.Rtf = richTextBox1.Rtf.Replace(@"\b0 ", "</b>");
richTextBox1.Rtf = richTextBox1.Rtf.Replace(@"\b ", "<b>");
|
|
|
|
|
Not that I know RTF, but this will seriously break it....

This will break if the bold is inside a cluster of RTF codes yes. The principle is the same though. Remove the \b and insert the <b> after the first space after the \b. For the end tag \b0 look for the \b0 and find the first \ in the cluster of those tags and insert the </b> before it:
Example:
\b\ul Test\b0\uln
\ul <b>Test</b>\uln
NOTE: Although there is no other offical RTF code that I am aware of that starts with \b you might want to check to make sure it really is bold and not the begining of something else. Easiest way is to search for "\b " and "\b\" instead of just "\b". That will find the bold tag if it is on the end of a cluster of RTF codes or in the middle. As for the \b0 you can do the same I guess but I can't imagine an RTF ever starting out with \b0.
