Common C Programming Errors or you can say "C alike"...
double fifty = (1/2) * 100;
This code sets fifty to 0 not 50! Why? Because of integer division.
If you want something nailed use hammer, if you want something sliced use a knife...

Indeed regex has all the tools in capable hands to chop the strings. +5

yesotaso 30-Jun-11 2:58am View

+5, one modification may be added: format could have been done with 2 arguments, anyway thats unnecessary detail. What I wonder is what advantage does StringBuilder holds against plain string concatenation. I know thats another question but is it simply "performance" or "principles of oop".

yesotaso 30-Jun-11 2:45am View

What he wrote is essentially correct OP should have reset the counter... But why there is a 2nd loop(That is from original code)?

yesotaso 30-Jun-11 2:43am View

Nice, but why does he even need 12 of each record (144 total). I think the inner do-while is put there out of confusion.

I dont have experience on web applications but I've read Push technology seems to be what you are looking for. Most probably you've read this aswell but if you google with keywords "server push" + some other relative words it might narrow down search window.

yesotaso 31-May-11 7:20am View

I cant imagine what downvoter was thinking :( apart from the typo there "end" => "and" it looks legit answer. Though I wouldn't use that logic and remove piece of input which may serve both "logical operator" and/or "the data itself", think of input "beast and beauty" the word "and" may serve both operator and input here. It might be better to construct eval tree from input text.

yesotaso 31-May-11 4:40am View

Well, the logic behind your pattern is a little bit insufficient. I dont know how it seemed to work in the first place. As you can see I did not search for "imgres?imgurl", yes that is close to result but if you dont pinpoint exact location of goodies in someoneelse's string you'd waste quite a bit of time searching your way. So the brackets '[' ']' are the key to pinpoint target you should have looked for those.

["/imgres?imgurl= repeats in given url 21 times ok but .*?(,"){5} doesnt make much sense to me.

Ref MSDN:
All LINQ query operations consist of three distinct actions:
1- Obtain the data source.
2- Create the query.
3- Execute the query.
So, in this context 3rd step is missing.
OK, then what?
Again MSDN: The query variable itself only stores the query commands. The actual execution of the query is deferred until you iterate over the query variable in a foreach statement. This concept is referred to as deferred execution.Queries that perform aggregation functions over a range of source elements must first iterate over those elements. Examples of such queries are Count, Max, Average, and First. These execute without an explicit foreach statement because the query itself must use foreach in order to return a result. To force immediate execution of any query and cache its results, you can call the ToList<tsource> or ToArray<tsource> methods.
TL;DR... you should have read it :P Correct answer is given by Wonde

public bool FromString(string input){
System.Text.RegularExpressions.Match m = System.Text.RegularExpressions.Regex.Match(input, @"(?<string>[A-Za-z]+)(?<number>\d+)"); // Kim's code
if (m.Success) this.Value = m.Groups["number"].Value;

Take a look at "http://www.homeandlearn.co.uk/csharp/csharp_s1p5.html" it might feel like "Submarine Operation Manual For Complete ..iots" if you have absolutely no C# Windows Forms it might give you a start. The rest depends on how you use "Properties" window and google :) oh I almost forgot holy "F1" key.

I have absolutely no experience in WPF what so ever but I am quite sure events arent handled quite different from windows forms. http://www.codeproject.com/Answers/202933/i-want-to-give-text-box-no-input-character-only-pu.aspx has a veeery long code block which defines how to not do it and Answer 1 explains how to bind many buttons performing a common task to a single event handler.
As for the algorithm... well I dont see much of an algorithm there I've looked at the links its just a naming system for teeth which could be relevant but that does not even remotely smell like algorithm.

It seems to me that you are shaking wrong tree... The IO itself is the bottle-neck, the idea of multi-threading is pipe-lining tasks so that with better usage of resources gaining performance, which would fail if one of tasks you try to pipeline takes %99.9 of time. Lets take an example, you copy 100MB of a file and copy it in ~10 secs, 2 consecutive copies would take ~20 secs but the fact is 2 concurrent copies would also take ~20 secs because of physical limitation which you can overcome only way : buy faster disk or buy motherboard with faster databridge DMA or whatever but it will cost dearly :)

yesotaso 27-May-11 5:25am View

First of all, like Rob said both Array and List can carry you to the destination, but Arrays require little more maintainance :) It is always good to use whatever you are familiar, but also far more better to widen familiarity circle. Anyway among many other, most striking difference is you can expand list on the fly... For the presentation Rob already given the code for that.

yesotaso 26-May-11 18:43pm View

No problem at all I figured later what was really going on but didnt have time to reply sorry about that. Anyway there are 2 solutions 1- Focus on content (thats what you did) 2- modify the repetition indicator of ".*" so that it would capture as least character as possible. so the final pattern should look like (?<=\"email\":\x20\").*?(?=\"). Answer is updated accordingly.

It is called "Race Condition" the variable "i" in that case is modified by another (or simply main) thread since you do not know when exactly the thread starts the behaviour of that loop is unpredictable. It might all be 9's or sequence like 222333399. To overcome that you may declare a temporary variable in that scope and use it as parameter.

yesotaso 26-May-11 12:18pm View

I was thinking same "why 2D array" the problem itself isnt just sorting 2D array but the Tariff type itself is also fishy.

I did not pre-calculate ray as I use "orthographic projection" whole tracing returns 3 RGB value and I write it to bitmap via for each ray
unsafe
{
byte* pData = (byte*)dat.Scan0;
int x3 = x * 3;
int y3 = y * dat.Stride;
*(pData + y3 + x3) = (byte)((output.red >= 1 ? 1 : output.red) * 255);
*(pData + y3 + x3 + 1) = (byte)((output.green >= 1 ? 1 : output.green) * 255);
*(pData + y3 + x3 + 2) = (byte)((output.blue >= 1 ? 1 : output.blue) * 255);

Excuse me for being blunt, you should seriously visit an SQL tutor. Such as http://www.w3schools.com/sql/default.asp. You cannot use code given by others as it is you need to know what they do as you read code. And you should have enough knowledge about the syntax about what you are doing so that you should see what is occupying where its not supposed to be. Like "...main_password = TextBox.Text ..." Your question "http://www.codeproject.com/Answers/197565/SQL-Server-Compact-3-5-Database.aspx" raises this impression aswell.

I think,
class IndexedDictionary<TKey,TValue> : System.Collections.Generic.Dictionary<TKey,TValue>

public TValue this[int index] {
get
{
if (typeof(TKey) != typeof(int))
{
if (index >= this.Count)
throw new IndexOutOfRangeException();
return this.Values.ElementAt(index);
}
else
{
var x = this.Where(p => p.Key.Equals(index));
if (x.Count() == 0)
throw new ArgumentOutOfRangeException();
return x.First().Value;
}
}
}
}
Edit: This should work as well, the "else" part requires a little re-work.

It is the logic that is flawed I mean. The first if fails second one is bound to fail because there is no "r.Rows[0]". If the first if does not fail you should check "DBNull.Value.Equals(r.Rows[0]["main_password"])" before assigning it.

In the "System.Management" namespace there are tools to query WMI service local/remote. While querying the remote machine "System.Management.ConnectionOptions" class has impersonation options. Just query remote machine with anything with given creditials. That is one possible way.

Take a look at "http://en.wikipedia.org/wiki/Closed_world_assumption". If combobox does not know what you give is a tree, that tree does not exist for it. You would need to teach (simply code it in the way you want to see) it or it will interpret data the way it knows - a simple list of unordered strings.

Sorry but I think there is a misunderstanding on my side, the article I linked uses "System.Windows.Forms.WebBrowser" and loops the html tags via the foreach statement you wrote above. I did same such as:
webBrowser1.Navigate("http://sports.ladbrokes.com/");
and after receiving "DocumentCompleted" event I was able to loop it... Anyway sorry for being little help, as stated above this is an example I've encountered around.

The method you use depends on default Font type-size etc. Think it lettor "O" as a little picture this method will align left side of picture to the coordinates you enter. Even if you calculate that and normalize it it wouldnt be the same with another font(another machine-pc etc). You should consider below solutions.
Looking at code: what did you do with "sizef". And is the size of picturebox equal to size of original picture? (ie. did you strech it?)

Propagation is the key of course. If there is an exception in the try block but catch block does not cover will the code not in "finally block" work. In OP's case it doesnt matter he'd catch base exception and show MessageBox etc and move on...
Side Note: I am not very fond of rethrowing if possible let exception pass your try block. Disposing older exception and trhowing new ones clouds the objective "stack trace"

Though your problem solved 1 piece of advice, check out your regional settings on your windows system "Control Panel -> Regional and Language Options" there you'd see how your system tries to parse numbers. You can customise as you wish (beware your installed applications also use this settings to parse stuff so caution is advised) change Decimal symbol "," to "." and Digit grouping symbol "." to "," that way you can parse floating points as "1234.678"

yesotaso 7-May-11 16:06pm View

Please re-phrase question.
What is wrong with above code? Does it throw exception (if so give details about exception, stack-trace etc.) You do not like the way it works an you want an alternative? It does not have a functionality you want to add but you are not sure where to start? I personnally cannot figure head-tail of the sentence following the code fragment... From what I can figure you have the url of image stored in XML but you want the image itself inside database - not the URL. But that assumption is not alone enough to give an answer(at least for me).

I am trying real hard what could possibly be the problem?
"(from b in blah select b).Distinct()" whatever you select the number of records comes from the "from b in blah" and the distinct only checks record level difference and you have control over that difference via "select"... Go ahead and try it yourself. http://www.sql-tutorial.com/sql-distinct-sql-tutorial/ for reference if wish to please your curiosity.

yesotaso 7-May-11 4:31am View

What does it have to do with performance? Besides if you include primary key, which happens to be uniques in the table, in distinct call you guarantee that all records are selected... Filter fields which set of fields you mean to be distinct and select them not whole record. For instance "...select p.Name, p.Department, p.School).Disticnt()" See above solution it is acceptable imo.

Text output may be deceptive. As 1 digit integer holds 1 byte in text 9 digit holds 9 byte.

yesotaso 6-May-11 15:12pm View

Well it doesnt seem very hopeful situation, but if you are going to use disk minimize whatever you can. On that scale even 1 byte makes difference, most probably such hindrance will deviate your focus from main obejctive... Anyway all I can add is keep 4KB sector size in mind (it may vary due to system settings but by default it is 4) even if you read 1 byte that whole sector is read from disk to memory.

The reference table "conversion" does not have "Customer_ID" as Primary Key simple as that. If you want to add such constraint, "references conversion(Prospect_ID, Customer_ID)" but of course you do not have Prospect_ID column "Customer_follow_up" table and Customer_ID itself doesnot guarantee that you get right "conversion" record. It is design fault. 1st solution I can think of is make only "Customer_ID" as primary key and put a unique constraint on "Prospect_ID ,Customer_ID". that way it will work BUT I do not know the intention of making a PK with 2 fileds in the 1st place this may hurt your design.

Sorry for late answer it was a busy day. Basicly yes it copies 1 class with "simple" attributes to another. If an attribute is complex (a class-struct) type you can recurse for that field aswell.
Side note: I did a few tests without recursion. that piece just copy fine. As I mentioned earlier array types or collection types may prove to be difficult.

Mathematical terms: Let a string be "WELCOME" then it may be considered as a set of letters 'W' 'E' 'L' 'C' 'O' 'M' 'E' a substring is a subset of this set like "ELCO"
which can be expressed as subtring starts 2nd char and length is 4 chars.
the statement in question means it starts at 1st char(because there is 1 number given starting letter is by default 1st one) and ends at i th char where "i" is the variable which represents the length of each line in the picture you sent.

Expressing your programming skillz is all good, but do it in a way that programs also reflect your understanding of business oriented problems in spite of how dull those problems might be(they usually are dull). It might seem "Sir! Yes sir!" approach at first but you need something to sell.

yesotaso 30-Apr-11 11:39am View

Indeed I am. For instance, you have some horses, carriages and a loading dock. To solve low performance you need to know how good are your horses, how balanced are your carriages, how good is your crane operators. If your operator is drinking at work or a horse is running to death with empty carriage or a huge carriage kiling horses you have a problem...
