hi
Thanks now im getting it right

hello everybody
i need to build a small program in C# that searches within a C source code (a txt file basically) for variables and method names and after that to replace them with something else. i can't do the first part. i've tried to do something but with no success. can you help me with some informations/suggestions?
thank you in advance

You must know all the keywords that can come before a variable or method name, like int, string etc. You will also need to check if the word there for variable declaration and elsewhere. ie word string might come in a comment text and then you will end up editing the comment.
All I can suggest is to make sure you know what I have written above. Then you can just take the very next word and replace it.

list the possible keywords, and try building a regular expression for them, since every line should end with ";" it might loosen writing the a regular expression for it, but it will be a lil tough.
good luck

When I populate properties in my classes, I usually use reflection to get values from a DataReader and set the values. What do you guys think of this technique? Below is a snipplet:
SqlDataReader dr = new SqlDataReader();
PropertyInfo[] properties = this.GetType().GetProperties();
dr.Read();
foreach (PropertyInfo pf in properties)
{
pf.SetValue(this, dr[pf.Name], null);
}

It's brilliant. Have you applied for a patten yet?

Thanks. I have been using this technique for many many years now. I always wondered if there was a performance penalty or other types of penalties when using this method. I never encountered any problems. I wanted to see what the experts had to say.

No you don't, that's twittering garbage. If your statement was true you would be reading the Microsoft Documentation rather than posting your garbage in internet forums.

If you think my posting is garbage, you did not have to respond.

How do you know what I have to do? Oh right, you're one of those guys that just knows stuff huh?

I think this is a bit odd, and reflection is generally quite slow

Not sure. Why would you do it this way? Does it offers something good?

I used this in a base class. When I inherited the base class in other classes, I did not have to worry about populating their properties (or performing other logic), the base class would do it. The other classes that inherited the base class were 'templates'.

I've done something similar as a learning exercise. Property names and values are read from an encrypted XML file, and I create it entirely using LINQ. It's actually remarkably elegant

That's fairly dreadful. Better to have a constructor (or initializer) that takes a DataReader and populates itself.
I don't see much point in having a class use Reflection to discover its own properties. Particularly if it's a base class discovering information about classes that derive from it.  That's a big no-no.
But if you insist on doing this; I would make one library method (perhaps an Extension Method) that takes both the object to set and the DataReader; and I would not have it use Reflection on each call, I would have it cache the PropertyInfo array the first time it encounters a class and then use the cache thereafter.

Hi there ,i am developing a game in which i want to use A*(A-star ) Algorithm for the enmey to detect the player position on the basis of the values on the data bases in which there are 5 attributes (left ,right ,up,down ,current).they have the zero value if it can not move to that direction
e.g left =0,right=2,up=3,down=0, current=1, if it moves to right then the current value becomes the 2 .
the problem i am having regarding the A-star algo is what is going to be heuristic h for it in F=g+h.how it going to be calculated what will be the critria for it.
thanks in Advance,

Why do you choose to put your post on this forum?
Why dont you try posting on a relevant forum like GameDev.Net forums[^]

There are hundreds, if not thousands, of 'Drawing/Sketching' articles, both here on CodeProject and elsewhere.
Search around!
When you find one you like, have a go at altering it to suit.
If you get stuck somewhere whilst doing that, then come back here with a specific problem.

In that case you might want to start with a spellchecker. 
Just kidding. Now to seriously answer your question. Is that your idea of requirements? Really? If you think what you posted qualifies as the entire set of requirements applicable to the question you posed, then there is nothing here anyone can do to help you, try as they might.
pwm1964 wrote: I want to start off on the "right" path
The right path, always has been and always will be, to study the techmologies you need to use so that you understand them well enough to use them correctly, period. The fact that you posted this question in an internet forum is a contradiction to your statement.
But good luck anyway ![Beer | [beer]](https://codeproject.global.ssl.fastly.net/script/Forums/Images/beer.gif)
