I have found some libs that can do this. Libs like ICSharpCode.SharpZipLib.BZip2.BZip2.Decompress(stream in,stream out);
I want to know how can they do this? I tried several ways but all with failure.

Makes no sense to me, FileStream derives from Stream

it works fine for me, as it should.

Hello guys,
I know this isn't the WCF Message board but the problem isn't directly with WCF. Now my problem is that at work in our application we have a main client that access certain information from a WCF that than that access the database. And the other business objects are stored in seperate dlls. Now an instance of the WCf service that we are using is being called from the mdi client. now the problem is that i want to access that instance of the service from one of my business objects without having to create a web reference to the service in that dll. Hope i explained my self well and you can understand me sorry if i didn't  Any help would creatly be appreciated.
Thank you
Regards,
Christian Pace

If you are asking if you can have application A call application X (WCF server) without using WCF or even sockets then no.
If you are asking if you can use functionality from X in A directly then that depends on the functionality.

A c# application (Visual Studio 2005) creates a SQL EXPRESS database file (.mdf)
How can I convert it in a text file (csv or other)?
thanks

loop through database and and when you get each item, save it to a file.
What kind of file is this .mdf? (I Know that .mdf and .mds are used by Alcohol when creating images from CD/DVD)

Why you bother to convert SQL server mdf file you can't. you can export the data in a CSV files. You just need to fill a dataset and export, that's it.

Use SQL Server Management Studio to access the database and export the tables to whatever format you want; including scripts, text, Excel, MS Access, etc.

I have created a report using excel but when i open it its centered on the last cell it wrote to. How can i save it to open on a specific cell ??
Thanks in advance

Excel always retains the cursor position in its worksheets. I guess all you need to do is select the cell you want it to focus on before closing the file.

Forgive me if my question is unclear, I'll do my best to clarify it as best as I can.
What I'm trying to do is "Tokenize" nested formula's by using RegEx.
Consider the following formula in LaTeX:
LaTeX Example 1: text before \frac{ \frac{ SubPart 1 }{ SubPart 2 } }{ Part 2 } text afterWhat I need is a RegEx that can tokenize this LaTeX formula to output the following tokenlist:
Token[0] = text before
Token[1] = \frac{ \frac{ SubPart 1 }{ SubPart 2 } }{ Part 2 }
Token[2] = text after
Looking at Token[1], it has a nested fracture (\frac{...}) in its top-part.
That's the way I need it to be to build an object tree.
In a sense, the fracture in the top-part is a child to it's parent fracture.
Consider the following formula in LaTeX:
LaTeX Example 2: text before \frac{ \left ( SubPart 1 + SubPart 2 \ right ) }{ Part 2 } text afterThis should result in the following tokenlist:
Token[0] = text before
Token[1] = \frac{ \left ( SubPart 1 + SubPart 2 \ right ) }{ Part 2 }
Token[2] = text after
Again, looking at Token[1], it has a nested subformula in it.
In this case, the subformula is a child, associated to the toppart of the fracture, to the fracture object.
Final example (and then I assume you catch my drift):
text before \left ( \frac{ SubPart 1 }{ SubPart 2 } \ right ) + X text afterThis should result in the following tokenlist:
Token[0] = text before
Token[1] = \left ( \frac{ SubPart 1 }{ SubPart 2 } \ right )
Token[2] = + X text after
The nested-/sub-formulas will be processed when the parent formula is being constructed, so we need not worry about that part of it here.
What I need, is a RegEx that can handle formula dimensions to the nth degree.
Right now I do this by stepping through the string and seeing if I have a match in the sub-string for a particular item.
When found, I add 1 to a level counter and run an internal loop to find the final closing "}" that brings the level back to 0;
This works fine, but I've been commented upon by using this method and not using tokens, begotten with the use of RegEx.
If anyone has a suggestion of how I should construct my regex, then please let me know.
I've gotten as far as:
Fracture : (\\frac{[\W].*?((}\s)|(}$)))*
Subformula : (\\left \([\W].*?\\right \))*
But as you would guess, this fails miserably when having to deal with nested or multidimensional formulas.
Any help and/or insight on the matter would be greatly appreciated.

For what purpose? Do your have example input and output?
|
|
|
|

The purpose is to create an object tree of the formula.
The examples may be found in my previous post.
These are simplified examples, mind you, but they are representative of the challenge.
Simply put:
Parent object is Formula.
Formula has a collection of child objects of the base type FormulaItem.
FormulaItem[0] could be of type SubFormula (\left (...\right )).
FormulaItem[0], being of the type SubFormula, has one collection of child objects of the base type FormulaItem.
FormulaItem[0].FormulaItem[0] could be of type Fracture (\frac{...}).
FormulaItem[0].FormulaItem[0], being of the type Fracture, has two collections (top-part and bottom-part) of the base type FormulaItem.
Etc...
I hope to have clarified the "why" in this.

Hmmm, not very friendly then. 
No worries, I'm always optimistic and don't mind a 'challenge' when I come across one.
I'll give you a more extended LaTeX formula example:
\left ( Availability~ \right ) \times \left ( Performance~ \right ) \times \left ( Quality~ \right ) \times 100 ~ =~ \left (\frac{ I}{II} \right ) \times \left (\frac{ III}{ \left ( IV \times I \right ) } \right ) \times \left (\frac{ V}{III} \right ) \times 100
This is an example from how it's actually being used at this very moment.
I'm not sure what more information you need to clarify the "why"?
"Nope" isn't a very articulate way of asking me for the information you require to clarify this to you.
So please let me know what it is you require of me other than what I've told you in order to clarify the "why" more accurately.
Just to recap, I need to objectify a LaTeX formula.
All I need, is a regex that is able to work with nested and multi-dimensional formulas as explained in the previous posts.
The reason I'm exploring this, is because I've been commented upon that I didn't use tokenization by regex to get the formula elements.
If there's anybody who knows how to tokenize a string that is a formula with nested and/or multi-dimensional elements, please let me know, otherwise I'll set this aside as:"Not a viable option, can't be done within a reasonable amount of time."

I'm not going to try and work it out myself, but you may find this handy: Expresso[^] - examines and generates Regular expressions.
Best bit is it break it down and explains it in English!
