Isn't that the Cariage Return code
Like '\n' is the new line feed code.

Certainly is. He put them in to format them so they would appear nice if ever they were printed out from code.

Environment.NewLine is rather really environment-friendly right?

It is, but don't tell him that. The real WTF is formatting this out the way he did though.

I would do that as:
@"
SELECT field1,
field2,
field3
FROM
mytable
";
It still puts the newlines in the string for when I dump a CommandText to a log.

That makes sense sometimes, especially if you're debugging [or logging rather] the actual SQL code sent to the DBMS.

To be honest, the time it takes you to do this is wasted time - especially, as I noted in the OP, when you are a consultant and thus billing by the hour.

no joke...this is from a code generator developed by an earlier employee.
SQL = "INSERT INTO Orders (" & _<br />
" OrderID, " & _<br />
" CustomerID, " & _<br />
" EmployeeID, " & _<br />
" OrderDate, " & _<br />
" RequiredDate, " & _<br />
" ShippedDate, " & _<br />
" ShipVia, " & _<br />
" Freight, " & _<br />
" ShipName, " & _<br />
" ShipAddress, " & _<br />
" ShipCity, " & _<br />
" ShipRegion, " & _<br />
" ShipPostalCode, " & _<br />
" ShipCountry " & _<br />
" )" & _<br />
"VALUES (" & _<br />
"'" & Orders.OrderID & "', " & _<br />
"'" & Orders.CustomerID & "', " & _<br />
"'" & Orders.EmployeeID & "', " & _<br />
DataCommonFunctions.SQLDate(Orders.OrderDate) & ", " & _<br />
DataCommonFunctions.SQLDate(Orders.RequiredDate) & ", " & _<br />
DataCommonFunctions.SQLDate(Orders.ShippedDate) & ", " & _<br />
"'" & Orders.ShipVia & "', " & _<br />
"'" & Orders.Freight & "', " & _<br />
"'" & Orders.ShipName & "', " & _<br />
"'" & Orders.ShipAddress & "', " & _<br />
"'" & Orders.ShipCity & "', " & _<br />
"'" & Orders.ShipRegion & "', " & _<br />
"'" & Orders.ShipPostalCode & "', " & _<br />
"'" & Orders.ShipCountry & "') "
Sql Injection anyone?!?
Whenever I put sql in code it's always on one line and I'm using parameters!

the coder wants readable code, so it isnt such a horror.

But a horror for the compiler.
|

compilers don't have feelings. they cannot be horrified.

I bet it was comments like this that led to SkyNet waging war on man....

The compiler makes one string of it all and so the empty string is "Over the hills".
I like readable code so much, that I often write a little more code and comments and think about value and class names up to 10 minutes. It helps me to make a 'master architecture' for my work. It has often paid off, because I can easy reuse code. I have to maintain 6 projects in which a lot of code is reused. The changes and enhancements for Vista I wrote 1 time and use it 6 times.

This is why I like the @"string" literal operator in C#.
private static final String SQL = @"SELECT
nvl( vss.structure_address,
ifsapp.serial_structure_template_api.get_pos(top_part_no, ...";

Wait... don't answer that.
So at work I'm doing up a quick and dirty ASP.NET application that uses a TreeView . I'm still a bit of a beginner to programming for the web so I've been through the installed MSDN docs quite a bit for the past couple of weeks but I just ran across something that utterly blew my mind.
Anybody who has worked with TreeView knows it's got a few quirks, namely dealing with the fact that it's biased towards hierarchical data (why else would you use it?). I haven't had a lot of experience using .NET collections for a lot of things so combine that fact with the fun hierarchical nature of TreeView nodes and I have a lot of help doc reading to catch up on.
So I'm trying to find some sort of way to get at a TreeNodeCollection index without having to loop through an IEnumerator like so:
'enumerate through the nodes on this level and find out what the currently selected
'node's index is
Dim nodeEnumerator As IEnumerator
If selectedNode.Parent Is Nothing Then
nodeEnumerator = trvTasks.Nodes.GetEnumerator
Else
nodeEnumerator = selectedNode.Parent.ChildNodes.GetEnumerator
End If
'Counter code goes here
I'm hitting random members and I happen to land on the RemoveAt page. No big deal, right? There's no good information here on finding an index or anything...
Whiskey.
Tango.
Foxtrot.
From the integrated VS2005 help:
C++
void button2_Click( Object^ , EventArgs^ )
{
if ( this->treeView1->Nodes[ 0 ]->Text->Equals( "Node0" ) )
{
this->treeView1->Nodes->RemoveAt( 0 );
}
}
Now I've dabbled in C++, and I've even done a little MFC in school, but is this really what you have to do in Managed C++? If C# is supposed to be all the best things about C++ then this looks like all the worst... No wonder nobody wants to touch the stuff.

Why? What's wrong with that? How else would you do it?
And why would you need to know an index anyway?
|
|

Well, when I was learning C++, ^ meant to the power of, /* */ meant some sort of comment, and -> meant accessing something through a pointer. From that stance, the method signature above contains an Object and an EventArgs to the power of... something, as well as two parameters that are essentially comments. Also, the first executable line tells me that you're going through the this pointer to hit the treeView1 pointer, which hits the Nodes pointer, which dereferences to the Text property, which somehow is also a pointer and must be dereferenced to hit the Equals method. Am I missing something or shouldn't there be a dot or two in there somewhere?
As for the index, I need to know where my selected node is so I can insert nodes before and after it. TreeNodeCollection does give me an AddAt method that takes an integer index parameter... but the collection doesn't give me any way to access a node's index.

That's actually relatively common in C++ for parameters that aren't used. You only have to give names to parameters if you reference them.

.net objects for the most part are all pointers* to the actual object. C# just uses the . for everything.
*until you box a value type, but that doesn't really apply to this situation.
This blanket smells like ham

in C++ ^ is the XOR operator, not power of operator...
though i have no idea what its supposed to be doing there in the function you posted

May I ask you where you learned c++, since to my recollection
the ^ symbol was never user as power of but was and is used
as an BIT wise Exclusive OR.
In Managed C++ however the ^ is also used as pointer to managed
objects 'newed' with gcnew instead of new.

Wow, I had completely forgotten that from my one year varsity of C++ back in '96. I still don;t remember the power operator.
|
|
|
|
|
C++ doens't have a power operator it has a power function
double pow(double x, double y );
see MSDN[^]

Sorry, you are correct, ^ is XOR in C++. I got it mixed up with my VB syntax, which uses ^ as the power operator.
|

Why are you using an IEnumerator variable in your VB sample? Can't you use a NodeCollection variable and do a foreach loop instead?
This blanket smells like ham
|
|

I could have used foreach instead, but I wanted my code to reflect the fact that I was enumerating the collection only to count it. I tend to think of using foreach as "I'm doing something to each of these items in the collection", so I thought I'd use IEnumerator to specifically call out to myself that I'm only walking the collection and not making any edits.
