Thanks for the fast reply.
It seems system.servicemodel is supported by only .Net framework 3.0, but i am using 2.0. so are there any equivalent methods in 2.0

Sorry, I (incorrectly) assumed you were using WCF.

I have a question about windowless controls. I need to make an control (actually a sprite control). If I derive it from control, I can't get the flickering to stop when I am drawing more sprites one on top of the other, and all of them updating fast. So no I need to make this control windowless(without a HWND), but I still want to keep the advantages of design-time.
So, can I make a windowless control but still set the control from the design-time?
Thanks in advance!

Derive from UserControl and make sure that DoubleBuffered = True.

Well, I can't derive from usercontrol, because usercontrol is derived from Control, wich in turn is derived from IWin32Window, i.e it has a HWND. This is exactly what I don't want, I want to do the painting with only one Graphics(the forms Graphics). And if I use a control, and 10 instances of it, each drawing one over the other() maybe with transparency, DoubleBuffer can't help me. I need something more "light" than a control, but still be albe the process events. Thanks

Any object can process events. Controls just map to events by default. Not quite sure what you are trying to do but, you will eventually need a Graphics object in order to draw. You can derive from Bitmap and draw on it using Graphics.FromImage. Eventually, the sprite will have to be drawn to a window using Graphics.DrawImage. The window you will be drawing too, should be double buffered.
Maybe you need to create an Canvas object and a Sprite object. Sprites get painted on the Canvas which is derived from a control. Canvas can be the source for Sprites to grab thier events.

Well, let me tell you in more detail. I have to write a 2D(maybe latter) 32 game engine. But I will eventually need to write many games wich are very simmilar, that is why i am first of all thinking of me(the developer). That is why I want to make visual controls, so I can make the game from the Designer, to write little code.
My problem is that I am sure that deriving from Control is bad behaviour, because that control is actually a new window. Actually, now i realise that the only thing from the control is the client area and the events + the design-time. I don't want to write code every time I put a sprite on the form, I want to add it from the toolbox

Your sprites cannot be seperate controls. You'll NEVER get rid of the flickering and you run into performance problems with all the damn PAINT messages flying around to dozens of windows, no matter what you do. Everything has to be drawn on the same surface which can then be drawn to the screen in one shot.
Instead of trying to force Windows Forms to do something it wasn't intended to do, use the right tool for the job. Check into the XAN Framework[^]. It's designed specifically for writing games.

Well, I now see that you are right, I can't use controls for game development. But I can't use XNA, because I am not writing games for me, there are thousands of users playing this games(actually they are casino games - slots, blackjack etc..) so I can't tell them that they need XP SP2, video card that supports Shader Model etc... My current game engine is written in C++ Builder, but I still don't use controls, and it is hard for me to write a lot of code, and when I open the project, my form is empty! I am now looking at managed directx, but my question is there any way to use something that "looks" like a control at design-time, but at runtime it's not?

If you're using this,

This becomes a moot point.
|
|
|
|

Hmm, I am not really understanding whats a "moot point", but I am guessing that you are telling me to stop asking? I don't know where to ask... My ideea is that I wan't to make my controls in a way that I would develop the game exactly like in flash..at design-time and use only little time coding. Is there any way I can do this?

It means "pointless".

I already told you. The quickest method is going to be the XNA Framework.
|
|
|
|
|
Well, I already said that XNA framework ask for to many requirements, I can't use it, because I am not writing this for me, but for a lot of clients that use the current games(written in C++ Builder) on any windows version. Plus, XNA doesn't give me any design-time help. I wrote my sprite as a non-visual component, but I don't know how to, for example, change a property and "see" the change on the screen.

Also, take a look at the Component class. It will give you your design time interface.

Hi to all,
I want to search a specific string into ListBox. how can i do it?
Pravin

Listbox class has Items property which gets the items of the listbox. You can iterate over them and search for the string you are interested in.
|
|
|
|

ListBox.FindString() and ListBox.FindStringExact()

- make Visual display line numbers: Tools/Options/TextEditor/...
- show exceptions with ToString() to see all information
- before you ask a question here, search CodeProject, then Google

Hello All,
I'd be grateful if someone could give me some pointers or recommend some good links on writing addins for Messenger Live. I'm a bit new to C# so I'm treating this as a mini-project to better my understanding. Essentially what I'd like to do is add a spell check facility to Messenger using Word's Spelling API's.
I've written a small addin for Messenger using some example code and found another good example of calling MS Words Spell checker.
The Messenger example code I'm looking for is how to add a button to the conversation window.
Also are there any security limitation on what I'm trying to do as I noted on MSDN that add-ins run in a security sand-box, using the "Internet Zone" permissions, they have very limited permissions about reading/writing files, modifying the system registry and so on. To make sure an add-in runs in a fully trusted environment, you should install your assembly in the GAC.
Does anyone have any suggestions?
Thanks in advance.

I'd bet that using the Word APIs to spell check won't be possibly in Messenger's sandbox.
There are plenty of other free, portable spell checkers/dictionaries you could use though.

Hello,
I have a datagridview that is updating its DataSource every few seconds. I am maintaining the same DataTable and merging any new data that comes in. I am having an issue with the behavior when adding new rows. Say my grid has 100 rows and the user is scrolled down to view row 50. At that time, the grid gets 100 more rows and adds them. I need to keep the user at their scroll position or keep them in view of their selected row. Cheers

Hi Everyone,
i need the C# code for exporting data in excel sheet to XML file.
Kindly help me out.
Thanks,

You can accomplish this using Excel object library and few lines of code
|
|
|
|
|
ok please let me know the code.
Thanks,
Srikanth

Excel object library exposes methods for opening excel files and saving them to the format you specify. If you explore Excel object library using object browser you will be able to identify those methods. No one is going to write instead of you.

Hi,
I am trying to print a file. The file can be word, ppt, xls etc etc.
Instead using the COM objects i want to print the required file, so i thought i would open the file through binary reader and then send the bytes to the printer thereby printing the required file!
Is there any other way? To print the required file
The printer setting are set in a way that the file after print would be saved in a default location!
