Thanks for your reply.
It doesn't matter if the text is chosen from the autocomplete list or the person is typing in something completely new. The return key never fires a keypress event anymore. Every other key fires the event. The return key instead causes the text to be highlighted.
I am not sure what you mean by validating the text in the textbox before using it. I currently do not validate the text, anything can be entered in the box.
Thanks.

After further investigation it turns out that auto complete only intercepts the keypress event for the return key. The keypress event gets fired appropriately with any other key. The other keyboard events such as keyup and keydown are unaffected by this issue so they can be used as a work around.
If anyone knows more about this issue please reply.

from a winform gui control a button or a event should run a command on the cmd.exe in the backend and how to capture the output of it in a string and desplay in a textbox
similarly if i have to issue/get multiple command and its correspondig output in hashtable,
eg, cmd1 its output
cmd2 output

Hi. I want to develope a software like windows or antiviruses.
It means i want to fix my programs problems or update some parts of it without recompiling it or installing it again.
For more information "like stored procedure programming" that doesn't need
any program recomipling I want to change my softwares updates
in customer's computer without installing new version of my softweare and
just install or copy it's service pack!
Shall i create dll base forms and is it possible?
Which reference can help me about this?
Tank you

you always need to recompile the code you've changed. You can distribute some code in dlls which the main program can use, and thus not have to update the main program. You can also use ClickOnce to write an installer that updates the program automatically when a new version is available.

The type or namespace name 'Xna' does not exist in the namespace 'Microsoft' (are you missing an assembly reference?)
I found this Xna/DirectX example in the Visual C# 2005 Express Edition help files.
But when I tried to compile it I got the error listed above.
I looked for this error and read somewhere that it was a bug. Which hadn't been fixed yet.
Is this true? And what do I do now if I want this program to run?

Impossible.
It looks to me like the error message is right, you need to have the Xna framework downloaded and installed, and you need a reference to it in your project.

I downloaded Xna Game Studio Express and if I understand it correctly that you then no longer need to install the Xna Framework because it was already installed with Game Studio?
I find this really interesting, but I think I will need to buy me a book about it.
Only a few days ago I figured that DirectX would be interesting to program and now I am already contemplating programming Xna class routines!!!
Anybody have any advice for me?

Probably. You still need to add a reference to your project, tho.

My core advice would be: a tutorial will have you entering code that works pretty quickly. Make sure you have a grounding in C# in general before getting in too deep, and make sure you take the time to understand what everything you work on does, before moving on to something else. Otherwise, you're not really learning.

I already found one or two tutorials, on the Internet.

I have very little programming experience, and some aspects of C# I don't grasp yet. But it is nice to learn by doing.
I was thinking I saw this SpaceGame starterkit, that would be helpful for someone's learning process, don't you think?

Absolutely. But, to really learn, you should start by doing programs like a console based calculator, and then build from there. otherwise, you will not really have a solid foundation, and you will likely establish bad habits that will be hard to break.
Ranger49 wrote: I was thinking I saw this SpaceGame starterkit, that would be helpful for someone's learning process, don't you think?
If the only way to keep you motivated is to start with a game, then if there are games tutorials, they are probably the best place to start. And, if you're just doing this for fun, it really doesn't matter if you end up writing production quality code, so long as you have fun.
Good luck, either way.

I was interested in LEX and YACC and found a few newer compiler compilers. The examples that came with CoCo featured a calculator...

I was looking for a way to see if I could let DirectX do the rendering and shading on my 3D drawing project for me, instead of programming this myself by hand. That was about a week ago, only yesterday I discovered Xna because I wanted to know if my 3D function could be fed to my graphics card. So that DirectX would draw my graphics for me.
I do realize that I know very little about C#. Even though I find the books I bought about it very helpful.
As it is I have already done things with C# I hadn't even tried in university in the 1980s.
I make everything public because I make small projects and that I don't want to be frustrated by a bug because I labelled something private. Still if I were more advanced I would use private and public where it would be most appropriate.
Thanks everybody for your comments.

There is a difference between a using directive and an assembly reference.
Do you understand both, and did you include both?
Visual Studio can't evaluate this, can you?
public object moo<br />
{<br />
__get { return moo; }<br />
__set { moo = value; }<br />
}

I don't know the difference, I read about both these terms in my book that I bought about C#. But I didn't think I needed to understand the details about it. Just like how I stay away from using get and set commands. In some 6 months since I installed Visual C# 2005 Express Edition on my PC I produced only a few projects and that I am amazed of the things that this SDK lets me do. So I am pleased about the progress I am making but that I realize I have yet a long way to go in the quest to master C# and .NET

This is an example of a basic best practice that you're likely to skip if you don't start with the basics. You should always have private members and public properties, and they should only be settable if absolutely necessary. The more a class hides it's members, the more robust it can be.

Spoken like a true master.
I think MVP stands for Master Von Programming. It's a german title or something.

There are very few C# 'masters' if you ask me. If everyone who started c# would master it eventually, this site wouldn't be as popular.
Anyway, you don't need to understand errrrrrrrrrrrvrything.
This is important though, to start using any SDK.
1. An assembly reference is telling your project that you're using a certain SDK, or another resource. You can do this by rightclicking your project in solution explorer, and choose Add Reference...
2. You should first check your project if it already has the assemblies referenced. Open your project in solution explorer and open the references folder. If it already has, then that's good. If it has an exclamation mark next to it, or isn't there, that's bad. Remove it (if possible) and continue.
3. Open the Add Reference window. Take a look around, and I think you should eventually find the XNA Dll's that you need. Don't know where as I'm not really familiar with the package. This might be noted in
4. Now, in every code file where you use any XNA related stuff, you need to tell Visual Studio that this is what you're trying to do. This is done by a using directive. You say [I Will be] using Microsoft.XNA.Framework;
5. Now there shouldn't be any more errors on missing assemblies.
Hope this helps at all.
In short:
An assembly reference, is telling the project (not the solution) you're using a certain assembly (can be an SDK, or another type of resource)
A using directive is telling a certain code file that you will be using a certain assembly, that is referenced. You can't use a using directive for an unreferenced assembly.
Visual Studio can't evaluate this, can you?
public object moo<br />
{<br />
__get { return moo; }<br />
__set { moo = value; }<br />

Hello, dear friends !!!
I need to make a ArrayList of Structures.
How can i do it ?
One nation - underground
|
|
|
|
|
Well, create the ArrrayList and then add instances of the structure.
By the way, if you're using framework > 1.1 I suggest using the generic List type instead of ArrayList.

C# 1.0 and C#1.1 are SO nasty here. In the absence of typed collections, I would write a wrapper class that allows me to pass my struct into a typesafe container.
Perhaps if you made clear your C# version and posted some code to explain where you have an issue, we can help further ?

I am using .net framework 2.0, visual studio 2005.
I want to make serialization of ArrayList structures books
struct strBooks
{
public string Author;
public string Name;
public int Year;
public int Pages;
public string ID_for_catalog;
}
I thought about what you had said. Would it be better to use array instead of ArrayList.
Like >> strbooks[] Book = new strbooks();

I need to change the font size of text using listbox in richtextbox
thanks in advance..

|

What do you mean ? You want a listbox to list the sizes ? Then you capture the index changed event and use the value to set the font size in the rich text box ? Which bit is causing you grief ?
