yeh you can use this library for TEXT,HTML,PDF(CODECS ALSO INCLUDED LIKE WMF),RTF DOCUMENTS,XML,GZIP,TAR,ZIP. I am not confirmed about PPT and DOC. but ITextSharp Includes the Bouncy Castle (open Source) Library which is related to Security you can create digital certificates and signatures using Abstract Syntex Notations like X 509 X9 more over you can use it for SMIME Implementation.

You should really learn to use the documentation coming with the SDK. In the "index" side panel there is a box named "look for", just type: "interop", "COM interop" or "data marshaling" in it and you will find a wealth of information. Alternatively, if you've got issue with the SDK documentation (strangely many .NET developer seems to ignore about its existence) you could go on MSDN: http://msdn.microsoft.com/library/default.asp?url=/library/en-us/cpguide/html/cpconinteroperatingwithunmanagedcode.asp[^] Anyway about array marshaling (let's say float[]) the documentation doesn't straightforwardly explained you wether or not the whole array is copied or not to a temporary buffer every crossing the managed/unmanaged boudary (I think some attributes control that behavior). But always have the solution to use unsafe code & float* in C# or, as I prefer to write my wrappers now, use ManagedC++ (v2.0, meach cleaner, leaner and less ambiguous).

Basically in C# you can call directly into C function that's "easy" thanks to interop! But you still have to declare the C function in C#, with correct data structure, sometimes it's not so trivial toredefine in .NET the C data structure. You might also have many function to re-declare, quite tedious, particularly if there is, let's say, hundreds of them!. And you might as well simplify the C# API compare to the C API. It's what a wrapper is for.

That's because the sample application that uses the control spawns a new shell (cmd.exe) for every command, so it doesn't remember previous commands. Hitting cd.. will make the current cmd.exe go up one directory, but then the next dir will run on a new cmd.exe and therefore would show the same directory. If you want to, you can spawn a single cmd.exe and redirect output/input to just that single exe, that would do what you want. amitmohanty wrote: Can I change the opacity of the control? I don't know if we can modify opacity for individual controls within a window, but you can try pinvoking SetLayeredWindowAttributes/ Regards Senthil _____________________________ My Blog | My Articles | WinMacro

Unless you consume so much memory that you cause system to swap (which I doubt in this case), I fail to see how this will speed up computation?? Memory consumption and time go against each other... besides AFAIK GC is optimized for cleaning small local varibles, so even if you could clear em yourself, maybe it wouldn't be the best idea. OT: I see you keep working with matrices... it would be nice topic for an article :) David

A double is a value type, not an object, so the array does not contain references. You have to exchange the values. --- b { font-weight: normal; }

It depends on what parts of your GUI you want to make transparent, windows forms have a Transparency Key property and an Opacity property. Try playing with these to get the effect that you are after. Kev

you could probably model your user variable like this public class UserVariable { private string variableName; private object variableContent; public string VariableName { get { return variableName; } set { variableName = value; } } public string VariableContent { get { return variableContent; } set { variableContent = value; } } public UserVariable(string name,object content) { this.variableName = name; this.variableContent = content; } // automatically write the content of the variable when used in // a string.Format public override string ToString() { return string.Format("{0}",variableContent); } } this could be the head of a series of specialised Variable.. just my 2 cents Denevers

There's no such thing. The only way to get this functionality is if you modify the project templates to include your reference in the default list of references for that project. There's no such thing as just typeing using ... and having the reference automatically made. The only reason you think you see this is because the namespace that your using is part of an existing reference. Try it, create a new C# application, but don't add anything to it. Look under References and you'll see that there is a default set already made. Look in the Object Browser and you'll find that every namespace under those references (the .DLL's) is available just by typing using ... at the top of your code. But this exists ONLY because the references have already been made. RageInTheMachine9532 "...a pungent, ghastly, stinky piece of cheese!" -- The Roaming Gnome

Note though that the code does not check if the matrix is square. It will happily turn a string like "1;2 3 4 5;;6;7;8 9" into arrays without complaining. --- b { font-weight: normal; }

Well, you know how to write a console application, generally, right ? Then you need to accept input, presumably a string at a time, and then parse it to work out what is being requested, I guess first by looking for numbers and operators, then working out the order of operations.

amit If you read the article posted by Colin, it is pretty interesting. The article was very interesting if you are a hardcore matlab user and seeing how one can exploit c#. In the mean time you can take a look at this http://www.codeproject.com/csharp/dynmatrixmath.asp In my opinion having come from an embedded systems background and moving into windows application development, I have to say that matlab is simply the best for prototyping algorithms quickly and efficiently. The answer is partly baised because i have used matlab for 8 years and c# for 3 months. If you are going to do simulations using the model developed in matlab you can always run it on a unix box as well. I have to say c# is fantastic for doing all the pretty window gui things :-) You can also do matrix calculations in c++ because i recall seeing someone develop c++ matrix libraries to give c++ matlab like matrix functionalities. cheers
