Hello!

Are you required to do that in C#? As is it based on a logic, not on procedure oriented approach, it should be do-able in languages like Prolog, which are logic based languages. If you need to do that in C#, then you surely have to do alot of work!

Regards,

Adeel

Do rate the reply, if it helps or even if it doesnot, because it helps the members to know, what solved the issue. Thanks.

To match your first example you'd need to write a natural language parser which would be a ton of work, so good luck with that one . . .

but here's an idea for your second example:
write a compare routine that takes two strings and uses the first string to compose a regex term and iteratively compare it to the second string, with each iteration replacing a single character in the first string with a wildcard.
Example:
to compare the two strings "Hello" and "hallo" your routine would compose the regex terms
/.ello/
/H.llo/
/He.lo/
. . . and so on, comparing each one to "hallo" until a match is made or you overrun the length of one of the strings. This algorithm should catch simple one-off spelling mistakes but keep in mind that the performance will totally suck, as it will be relational to (the string length * regex computation time).

If performance in you app is an issue then maybe this won't be a feasible solution for you but maybe the experts here can provide some optimization suggestions or alternative ideas Smile | :)

Nice one. I would take your regex idea further to acheive sentences matching on his first example, by matching each word in the first sentence to any word in the second sentence using this matching algorithm (override IsEqueal using this algorithm), and if all words match, then you have an overall match.

This would require both sentences to have the same number of words to achieve a total match, it would then be your call to determine what to do with the extra words.

Now I won't even try to discuss performance on that one!

Connect, Accept, Send, adn Receive, are all blocking methods, when you call them it will just wait until you have Connected, Accepted a connection, Sent data, or Received data.

Begin... are asynchronous, which means they get called, and then the rest of your code is executed. When you call them you supply a callback function, so then when something happens, the callback function gets executed, and you deal with the send / receive etc. in there, and then usually call EndConnect, etc.

If you hop on over to google, and type in these methods, one of the top reults will be MSDN, which will tell you in alot more detail what each of them does.

hi,
I am working on a desktop application which has grid in it and show data from access database.
my problem is that the grid only shows about 21700 records of the table,(I am not sure about the exact number)
I can search throw the whole database (i can search for last added record which doesn't appear in the grid).

what should I do to show larger range of data in DataGrid?

What sort of dll is it ? Is it a resource dll ? What files are you hoping to get out of it ? Where did it come from ?

If the dll is written in one of the .NET Framework languages then you can use Reflector for .NET[^] to decompile it.

Timer Issue-Stack overflow exception

Hi
I created an windows application in C# which contains one form and one class file.In form I have one timer control and Timer1_tick event. In event I am calling a function in the class file. And in class file iam creating the object of form and calls the timer1.Enabled and Interval properties. When I refer this exe in other applications to perform Timer operations, I am getting two kinds of errors for two conditions.

If i am giving a "new" reference to the objects I created for the class and form in Timer exe, then - Stack overflow exception

If I am creating object without "new" and assigns null and uses to avoid Stack Overflow exception, then the error will be "Object refernce not set to an instance of object"

What is the solution to this problem?

NB: In VB they uses "friend" functions and Withevents to create object and avoids this situation
With Regards,

Abraham Chethuvelil

Christian Graus8-Dec-07 21:48

The 'friend' keyword in VB is just the same as 'internal' in C#. I don't see how that would solve your problem. Also, withevents is just a shorthard for assigning an event. You've obviously created a situation where your code just keeps calling itself. I'm not sure why your class is setting up a timer in your form, but if you set a break point you should be able to work out quick enough what is causing the endless loop.

Hi,

The exe is created to perform two tasks in another windows service application I created.

One to use the Timer_Tick event at particular intervals. This event calls the function(void OnTimerEvent()) defined in the class file which works as a wrapper class,

Second, this Wrapper class contains another user defined(delegate) Timer event that I created to perform some operations in Windows service appln. The issue is that OnTImerEvent() Method calls Timer event and the Enabled and Interval properties of TImer control I created in the form.

So I am forced to create the object of form in Class file, and in the form i have to create the object of wrapper class. This class is used in Windows services to define the Timer events

This is the problem I am facing, when runs This timer tick will be invoked at intervals and I get the errors I mentioned in the previous mail based on the use/removal of "new" "<constructor>"

Please help me in solving this

With Regards,

Abraham Chethuvelil

The timer event calls itself ? Well, that would do it.

If that's not it, try posting some code, then perhaps I can see your error.
