I've run large log files for new processes, full throttle on Debug level. Also, unknown or old code may have large log files. Size is not the problem here.
What I've done is read the articles on making an xml file or database (after xml) of a logfile. There are good articles on using .NET regex to parse a file and put it into xml.
An overview article, a bit light on details, is
http://msdn2.microsoft.com/en-us/library/ms972965.aspx
This way you can rationalize the files, normalize them to a dB, then really look at the contents.
Good luck.

Finally got a chance to look at the link you provided.
This looks like it will work. I never expected I’d be able to simply locate the desired data based upon its pattern, but I was able to write a RegEx using Expresso that does it (at least on a small sample log).
Now all I need to do is code it and see if it will work for the big files.
Thanks!

Also, rereading your original post, you need some grammatical structure here. Read the articles on Yacc, or for .NET anything that is a Yacc-like parser. The article on
http://www.codeproject.com/csharp/minossecc.asp
seems helpful. Search around, I can't put my finger on it but there are other non-Java .NET parsing meta-languages to help with the file structure.
There's always MKS Lex and Yacc -- I've used a long time ago to great effect, not too hard to learn (days). But, find something free if possible.
Cheers.

I'm overriding an Equals() method in .NET which a type specialization in mind but don't want to kill my code in stupid ways. So:
public override bool Equals(object obj)
{
if ( obj.GetType() == typeof(double) )
// foo
else
return base.Equals(obj)
}
The line to optimize is "if ( obj.GetType() == typeof(double) )". The constant typeof(double) calls is a waste. Tried "if ( obj.GetType().Name == "System.Double" )" with horrible results.
Any optimizations out there? Thx!

You could store the result of this call to a variable that's used by the comparison.

if (obj is double) ... else ...

if (obj is double) wins!
Gives me 2x speed over obj.GetType() == typeof(double).
Thanks!

As far as performance goes, there are only two rules:
1) shorter code is always faster
2) rule 1 is false

I didn't think that 'is' would work for a value type ? Or is that just 'as' that won't work ( as it can't return null ) ???

Sure is is always OK (it produces a bool) whereas as is not.

Hi, I want to replace any 2 words if found in a line. The 2 words can be on the same line or one on each line.
string line ="hello World, expression";
Regex regx = new Regex("hello"); //how can i optionally put to search either, "hello" and "expression" in a line
if (regx.IsMatch(line))
{
sb.AppendLine(regx.Replace(line, "replaced"));//if "hello" put "H" or if "expression" put "E"
}
Thanks

You can use the replace method on the string class, you don't need regex for this. There is a RegEx.Replace if you prefer.

Hi again!
Last Problem get solved very fast - thx to Luc! This time, i had another problem with printing...
How do i get the last page (number of page) that will be printed at PrintPage - Event?
i want something like that:
Page 1 from 9 (where 9 is last page that will be printed)
i want to print Page x from x on any page... at footer line - anyone does know an solution for?
i did something like that
private int LinesThatFit(PrintPageEventArgs e, PointF curPosition)
{
int CalcSum = (e.MarginBounds.Bottom - (int)curPosition.Y);
int CalcRows = CalcSum / newFont.Height;
return CalcRows;
}
this works - but only for a static height - or better a static font height - i draw a string by DrawString - but if it's wrapped, the LinesThatFit doesn't work correct...
Thx again for any solution - i searched for this problem around 2 days... and found nothing - the LinesThatFit is an own creation... but that was when i just had line for line with none wrapped text!
Hope someone get's it!
Bye!

put a counter if you are calling your print function last time then use if condition and then
e.Drawstring(.....);

ok the problem is that the query cant run multinline / one option will be to replace all linefeeds but this sucks.
has somebody any idea how can i match over more lines ?

If you use SingleLine mode, the regex works. Just tested in Expresso

Is it pssoble to use a VS.net wizard at runtim?
For example I want to use "TableAdapter Configuration Wizard" at runtime to generate Dataset.

|

No, it's part of VS.NET, not part of the runtime.

Hello,
I have a listview on my form, but I do not want it to respond to keyboard input as I want to use the keys for something else.
Currently, when the listview is populated with items and I press a key (say, the 'm' key) the listview will change selections to the first item that starts with an M. I would like it not to do that please. 
I am guessing this is where I can use 'protected override' (or something like that) however I am new to C# and I haven't grasped that yet.
All help is most appreciated. Thank you
... Andy

I like to find out programatically the users for the printers in C#
That is if you go to start -- settings -- printers and faxes and select a printer and right click
its properties you should find security there.
I want to access the users inside that security and see if a particular user is there programatically.
I did some research and found out that Win32_Printer class can be used to get all the printers connected to
a computer but not able to figure out how to get to the security of it.
Any help is greatly appreciated.

Hi, I have an windows Form which I don't want user to resize. In VS2003, I remove the minimized, maximize button, set the Locked property to true and everything is OK. Now, I upgraded to VS2005, this don't work anymore. The window can be resized. Is this a bug of VS2005? How can I do it? I tried to set max size and min size to the same and now the form has fixed size. But when I move the cursor to the edge of the form, cusor changed to hint that I am allowed to resize window. It's annoying. So, I don't think this is a good way to do it. Do you guys have any good idea?
Thanks.

You need to set the frame to be fixed, this is a property on the form, which I don't think has changed.
