That's the regular behaviour you get in every text editor under windows that allows for formatted text.
If you really want to do syntax highlighting in your RTB yourself (although there are several articles here on this topic), you should reconsider when to perform colorization.
If you do it whenever the text is changed or when a key is pressed, then you'll find out that like + the letter you typed isn't a keyword anymore, so the whole word should be black.

Hi,
I am trying to convert c++ code into c# code, and I am having trouble with arrays in structs.
The c++ struct looks like the following:
typedef struct {
int nAs;
int As[8];
int nBs;
int Bs[12];
int nCs;
int Cs[30];
} AN_ENTRY;
After quite a bit search, I figured out the definition can be changed to this:
[StructLayout(LayoutKind.Sequential, Pack = 4)]
public struct AnEntry
{
public int nAs;
[MarshalAs(UnmanagedType.ByValArray, SizeConst=8)]
public int[] As;
public int nBs;
[MarshalAs(UnmanagedType.ByValArray, SizeConst=12)]
public int[] Bs;
public int nCs;
[MarshalAs(UnmanagedType.ByValArray, SizeConst=30)]
public int[] Cs;
}
But how would I go around and initialize such a struct, I mean they are 53 integers that need to be passed in to initialize this? Can I do the following?
AnEntry anEntry = new AnEntry(1, 1, 1, 1, ....., 1, 1); // 53 1's
Do I have a define a constructor in the struct? If yes, the argument list of the constructor would be REALLY long. What if I need to create an array of AnEntry? Any suggestion or comment is highly appreciated. Thanks a lot.

Usually when your passing a new array of something into a constructor / parameter, you would do something like this:
AnEntry anEntry = new AnEntry(new int[53]{1,1,1,1,1,1,1,1...}) ;
make sense?
|
|
|
|
|
But do I need to create a constructor inside the struct? If yes, I will have to list all those 53 parameters? Thanks.
|

Where do you take data for the struct instances?
If data are taken from a database then you can create constructor with one parameter (record identifier) and load data within this constructor. Or you can add Load(int id) method to your struct. If data are random then you can add FillRandom() method. And so on.

in a textbox when user enter some input after that i want to check wether user enter only alphanumeric values or any special char like *&$@!":. if user does i will inform the user that input string is not valid
my question is how i will find out that user has entered special char.
reply soon
|
|
|
|
|
string input = textBox.Text;
if(!input.Contains("@"))
{
}
Does that help?
|

thanks

Override the text box and overrid the following method
protected override bool ProcessKeyMessage(ref Message m);
There are other ways as well but this one is fairly simple.

Hi all.
How can I get a Flash object to work correctly with the .Net 2.0 WebBrowser Control.
Best way to explain my problem is with a small project.
Open Visual Studio 2005 and create a Windows application (c# or VB).
on the main form, place a System.Windows.Forms.WebBrowser.
on the Forms load event, send the webbrowser to this page (http://www.helloworld.com.es)
scroll down the page until you reach the small color chart.
now click on the colors, you will notice it will only play the flash once.
In order to play the flash movie a second time you need to click anywhere on the page, then click on the flash movie again. The flash behaves as expected in all other browsers. (you can check with IE)
Has anyone please got some ideas for a work around.
many thanks
sean

Well It might be the behavior of the control. Have you viewed source to see that the Loop property isn't being changed?
1 line of code equals many bugs. So don't write any!!

Hey, I'm corrently building an IRC bot, using Threshers \ SharkByte IRC client.
It has a Connection class, which uses Threads.
I have 2 forms, a connection form, and a controling form.
After the user sets the data in the connection form, and logs in, I need to "move" the Connection obj into the next form.
but I can't cuz the Thread is throwing an error.
How can I still do something with it? or how can I move it?
Please help.
NaNg.

Might be helpful to know what the error is you are getting.

"cross-thread operation is not valid: control "frmconn" accessed from a thread other than the thread it was created on"
this is the error.
|
|
|
|
|
I'm not familar with the tools you mention but if frmconn is a windows control then it is not possible to "move" it to another thread. It must interact with the UI thread in which it was created.

A connection object is not guaranteed thread safety when used between threads. So you may want to use separate connection objects for your threads.

when is it appropriate to use a Dictionary and a Hashtable?
Dictionary <string, string=""> cacheLanguage = new Dictionary<string,string>();
Hashtable table = new Hashtable();
|
|
|
|
|
a Dictionary is a generic collection where as a Hashtable is just a collection. So if you need to use generics use a Dictionary, if you don't use a Hashtable. Otherwise, they are identical, think of a Dictionary as a Hashtable for generics, just like ArrayList and List.
btw, should be:
Dictionary<typeOfKey, typeOfValue> cacheLanguage = new Dictionary<typeOfKey, typeOfValue>();

Because a HashTable uses object for both the key and value it is possible to do soemthing like this
Hashtable ht = new Hashtable();<br />
ht.Add("one", 1);<br />
ht.Add(1, 1);
Not very type safe and it incurs the boxing/unboxing penalty. Where as the Dictionary uses the specified types for key and value the above would not be possible (unless you used object as the key)
only two letters away from being an asset
|
|
|
|
|
So basically the two does exactly the same thing, but Dictionary is just type safe? Does a Dictionary also hash the key when storing key/value pairs? They say Hashtables are optimized for fast retrievals and that is what I need for a multi-lingual website.

If you have very few items a hashtable is the fastest.
A Dictionary is still a key value pair and boxes unless you use a generic.
Dictionaries are easier to use than a hashtable. But, since you will be storing many words or something, then a dictionary would be more useful to store unique sets. But, then again thats why globalization namespace was made.
1 line of code equals many bugs. So don't write any!!

Dictionary class is implemented as a hash table and it's a generic class and performance wise it's close to O(1). Therefore I'm not sure why would one use hash table unless for backward compatability.
