Hello There,
Here it is:
INSERT INTO Jobs (ProjectID, FileName, SourceLanguage, TargetLanguage, Type, CharCount, PageCount, ApplicableRate, QuotedOn) VALUES (34058, 'D:\UI\Projects\2007\34058 (Company)\Sample Document.doc', 0, 1, 1, 71325, 71,325, 25, '05.11.2007 19:56:19'); SELECT SCOPE_IDENTITY();
It is right there, 71,325 is actually 71.325 in English (71325 / 1000). I suspect that is the cause of all this.

Yep, it looks like you found the issue. Try overriding ToString() method and convert it to the correct format for SQL Server.

Hogan Hi,
Overriding ToString is not problem but... All calculations are made in the program; storing what is inappropriate for OS regional settings would complicate my calculations. In fact, changing the field type to string and storing Turkish notation decimal (i.e. 71,325) would be a workaround; but ideally there should be a real solution for this.
Isn't there any localization settings in MS SQL server?!?

Two thoughts for you...
First, I know that you can localize strings in SQL server by setting their "collation sequence". That is useful for the order by for a specific language. But you want to be dealing with numbers here.
Second, from what I understand, the numbers you see are all stored in memory the same way. When we output them, they are filtered by region. With that being said, you should be able to put numbers in and pull them out without issue. I would try the following.
When you are creating your SQL try this. (pseudo code below)
decimal calculatedNumber = 71,325
In your SQL statement use the following statement to convert your number to an acceptable format
<br />
calculatedNumber.ToString().Replace(",",".")<br />
When you are getting the value back out of the database, you should be able to just do a straight assignment and get the value as you need it.
<br />
calculatedNumber = (decimal) dataReader["CalculatedNumberField"];<br />
Hope this helps.

The most apparent thing here is that you are using direct SQL to achieve this. You should use a stored procedure instead because it is better for you with regards to SQL Injection Attacks and also it takes care of the mappings for you.
CREATE PROCEDURE dbo.SaveJobs
@ID BIGINT OUT,
@ProjectID BIGINT,
@FileName NVARCHAR(255),
@SourceLanguage BIGINT,
@TargetLanguage BIGINT,
@Type BIGINT,
@CharCount BIGINT,
@PageCount DECIMAL(10,4),
@ApplicableRate DECIMAL(10,4),
@QuotedOn DATETIME
AS
INSERT INTO JOBS(ProjectID, FileName, SourceLanguage, TargetLanguage, Type, CharCount, PageCount, ApplicableRate, QuotedOn)
VALUES (
@ProjectID,
@FileName,
@SourceLanguage,
@TargetLanguage,
@Type,
@CharCount,
@PageCount,
@ApplicableRate,
@QuotedOn)
SET @ID = SCOPE_IDENTITY() Then you create a SqlCommand in your C# and fill in your parameters with the relevant values.

Hi,
if you had to search 50000 lines of code for the word example as fast as possible, with every kind of whitespace in the line, which method would you prefer.
REGEX
or
myString.Trim() == "example"
|
|
|
|
|
May be Regex, which compiled into assembly, but I'm not sure. It's better to test.

In this case RegEx would be the only one that works.
The second example would only ever return false.

Why not try it out for yourself and find out. Create a document containing the phrase "The quick brown fox jumps over the lazy fox" by cutting and pasting repeatedly; it won't take you long to knock up a 50000 line document with this in. Now, put a seed word in the middle somewhere - call it seed for instance.
Then, run a program that uses both versions against this document and see which method is faster.

Ok i wrote a little app that compares the two methods.
I found out, that testing a file with 60000 lines 30 times took my pc about a second with this method:
<br />
using (StreamReader rIn = new StreamReader("test.txt"))<br />
{<br />
string line = "";<br />
while ((line = rIn.ReadLine()) != null)<br />
{<br />
if (line.Trim() == "{{{tcl")<br />
{<br />
return true;<br />
}<br />
}<br />
rIn.Close();<br />
<br />
}<br />
return false;<br />
and about 9 seconds with the regex:
<br />
using (StreamReader rIn = new StreamReader("test.txt"))<br />
{<br />
string line = "";<br />
Regex reg = new Regex(@"\s*\{\{\{tcl\s*");<br />
while ((line = rIn.ReadLine()) != null)<br />
{<br />
if (reg.IsMatch(line))<br />
{<br />
return true;<br />
}<br />
}<br />
rIn.Close();<br />
}<br />
return false;<br />
Thats a BIG difference.

A well deserved 5 for answering your own question.

I am writing some code which calls a web service that i wrote. Works just fine when i pass in all of the parameters via the method call (names have been changed, duh):
public void SetOption(string A, string B, int C)<br />
{<br />
this.Invoke("SetOption", new object[] { A, B, C });<br />
}
However, when i try to set "A" from within the method:
public void SetOption(string B, int C)<br />
{<br />
string A = (from global source which has been verified to be active);<br />
this.Invoke("SetOption", new object[] { A, B, C });<br />
}
This sends a null object to the web service, which gives it a headache. 
Has anyone run in to this problem before? (when i simply switch it back to the passed in parameter, it works fine again)

Why your using invoke to call another function in your web service is beyond me.. . But, you could try just:
public void SetOption(string B, int C)<br />
{<br />
this.Invoke("SetOption", new object[] { ([A] from global source which has been verified to be active), B, C });<br />
}
Just specifically put the A value in with the arguments instead of making a new string instance.
|
|
|
|

Let me clarify, the invoke is being called from the web service client. (entirely seperate visual studio project)
I receive the same results using your suggestion. (a null object is passed to the web service instead of the string)

Try to seperate the web method into two different methods. One with as an internal helper with all of the logic.
public void SetOption(string a, string b, string c);
private void HelpSetOption(string a, string b, string c);
Although, a soap extension may work better for parameter replacement.

I tried this as well while testing. The system then complains about accessibility, and won't function until i make it public again. I tried with "protected" as well.
Thank you all for taking a look at this.

The web method must be public however :
[WebMethod]
public void Foo{string a, string b, string c}{
HelpFoo("test", b, c);
}
private void HelpFoo(string a, string b, string c){
...
}
Should work just fine.

A private helper function isn't useful for objects outside of the class. And as you have pointed out, the web method has to be pubilc, or:
System.ArgumentException: SetOption Web Service method name is not valid.
So i have two public functions, and it seems i'm just stuck at that.
-Jeremy A. Cunningham

Then make it public or internal and don't decorate it with the WebMethod attribute.
Realistically all web method calls should be immediate proxy calls to another class anyway.

TopicID ParentTopicID TopicName
0 0 Computers
1 1 Programming
2 1 C#
3 1 C++
4 1 Java
5 1 Perl
6 0 Operating systems
7 6 Windows 2000
8 6 Windows XP
9 6 Unix

and so forth....
The question is, what is the best algorithm to use to achive the above results?
Thank you very much in advanced!

I suggest the critical thinking algorithm. Good luck on your assignment, it's an interesting one.

If the datasource for this is SQL Server 2005, then take a look at using Common Table Expressions (CTE). They will sort this out for you no problem.
