You can do pretty much any programming problem in C#.

Sounds like you are asking for homework answers. This is a no-no. Also, please title your posts more appropriately rather than just using 'help.'

I think he assumes we have mind reading abilities to know what is ch5

I agree. I just love 'help' threads

You can rewrite the question like this:
I have a homework assignment. I noticed a similar example in another language in chapter 5 of this book.... Can you rewrite the example for me in C#, so I can hand it in.

very thank for your advice edboe , all you write is right and this is the problem can u help me edboe.
the question in liked list in data structure, the problem is that i want an algorithm or code in c# for this case that say write a program which reads an integer K and prints the list of clients of lawyer K and test the program for each K.
i know there is a pointer in c# but how i can make it.
thx a lot

Could anyone tell me how I could replace the system tray clock? I have seen a lot of applications do that, like ChameleonClock, and would like to do one myself. If somebody could give me some clues on doing that, I would really, really really appreciate it.
Thanks

I looked into doing that about a year ago. From what I remember, it required jumping through some very complicated hoops to get it done. I think you had to get the window handle of the system tray, then the handle of the clock window, take over the message pump of that window and intercept certain messages for painting. Your code essentially replaces the drawing code of the original clock... I think!

Nah, I don't really think it would be *THAT* complicated. I saw a I guy did something like this, but had a problem somewhere else, and said "I replaced the system clock, / that was simple /, but then got into some trouble..."
So I think there should be a simpler solution to this.

No, not really. There is no seperate Clock.exe or service putting that clock up. It's built into Explorer.exe, so I seriously doubt he "just replaced it".
He more than likely wrote his own clock and put that up in the system tray.

So, do you have some code snippets, or anything to start with, because i couldn't really understand what you said before thoroughly...
Anyhow sounds very nasty, and i wonder if it was possible for a process to draw into another process' area... If it was, that could be a huge security flaw in windows... I mean i could go on, and change any window's contents...

Nope. Just a few hours of Googling taught me what needed to be done, including finding the correct window handle, processing of the messages, and code injection into another process.
Vandra Akos wrote: i wonder if it was possible for a process to draw into another process' area
Yes it is. All you need in the handle to the window you want to draw in. Keeping it drawn the way you want and not having the application overdraw what you've done is the hard part.
Vandra Akos wrote: If it was, that could be a huge security flaw in windows... I mean i could go on, and change any window's contents...
Not easily, but it could be done. It's not as big a problem as you might think, though. There are security restrictions on some of the Win32 functions that you have to call to pull this off. If your a normal User, then you can't make some of the calls required to do this. If your an Administrator though...

uh, huh?
I don't want to create an icon, I actually want to replace the system clock part in the status bar, you know where it says 15:02, something more cool, and with a pop up-menu or something like that
|
|
|
|
|
Well, you can remove the standard system clock, and create your own application,
using one (or more) NotifyIcons, where each of these icons shows (part of) the date/time/whatever, and gets updated regularly.
Main drawback of this approach is you have no control over the icon position (although
icons created in sequence by a single application seem to stay together).
The referenced article shows you how to safely update an icon that is in use.

Am to develop a .NET application using C#,but this application will connect to the server which is a linux box.
Download some data from the MySQL database there ,then disconnect.
Does some one know how i can go about this?
Regards
Waskira

Do you dial directly into your linux box? => configure a dial server on it
If you have already a IP connection (maybe through a networking provider) then you just need to create a webservice. Have a look at mono and xsp.
For dial in configuration maybe have a look at: http://developers.sun.com/solaris/technotes/linuxppp.html
mono, xsp: http://www.mono-project.com/ASP.NET

Am thinking of going stand alone not web-app.
Another thing is yeah,am dialing into the box.
So,my part is getting the client application talk to the serial port.
So how do i get it to talk to the serial port

Is there a way to open a new console window in a Console Application? I'd like to display some output messages in a secondary screen rather than on the main one.
The alternative would be to display a form with a textbox...
Thanks.
|
|
|
|
|
How about : Process.Start("cmd.exe");
|
|
|
|
|
A console application can't have multiple windows like the windows environment. If you insist on your desing, you can make another console applcation that takes your output as arguments and display it in its own console window. In this case you can use Process.Start() ta launch your second console application.
Notice that your first application will have no control on the second one once it has started.

My experience with Windows services is that you have to login the service with a user account to use any network operations.
So try to change this:
//# Service Account Information
serviceProcessInstaller.Account = ServiceAccount.LocalSystem;
serviceProcessInstaller.Username = null;
serviceProcessInstaller.Password = null;
into:
//# Service Account Information
serviceProcessInstaller.Account = ServiceAccount.User;
serviceProcessInstaller.Username = yourusername;
serviceProcessInstaller.Password = yourpassword;
With the correct values of course...
