Add event to a WPF custom control library in Windows Form

why i dont use picture box ..??

The point of that control is to allow limited viewing of images for people too inexperienced to write some basic code. One you want to do anything more than show the image, the control will get in the way, it will not help at all.

Hi
I'm currently working on a project using C# Windows Forms. I need to add some animation on the form and I found WPF can do animation very easily. I'm very new to WPF. I searched on google and found some tutorial. Now I can add a WPF user control library to a windows form and the animation works fine but I need to control the animation, eg. When the user control library got focus, the animation starts? How can I do this??

Help please!

Thanks

Execute code in another process?

13-Sep-09 18:36

I don't know if that's possible. Perhaps you should ask in the WPF forum. I am certain it will not 'just work', if it's possible at all, it will be a fair bit of work to do. I know yo ucan write a WPF app and put some winforms controls in it, but not vice versa.

I'm writing an Outlook add-on but some of the things I need to do to the Outlook window are only allowed to be done by the process that owns the window. Is it possible for me to execute a line of code from Outlook's process?

Have you tried the Krypton Toolkit? http://www.componentfactory.com/free-windows-forms-controls.php

Correct me if I'm wrong, but aren't Outlook add-ins always loaded into Outlook's process space?

The addon is loaded somewhat separately from Outlook's main process.

Handle exceptions in GTK#

Not unless Outlook provides an interface allowing you to do so.

Hi!
So if place try/catch block in Main() function

try{
    Application.Init ();
    MainWindow win = new MainWindow ();
    win.Show ();
    Application.Run ();
}
catch(Exception baseExc){...}

and then throw exception in button click event, this exception will not be catched! Any ideas how to do it?

the real question is what exactly are you trying to achieve with throwing an exception in a button click event??

Christian Graus13-Sep-09 13:10

13-Sep-09 13:10

If you're trying to write code to handle any unhandled exception cleanly, then there's an event you can connect up in your init code, which will fire for any unhandled exception in your app.

Yes, I know. But I couldn't find it. All send to Application.ThreadException but it is for WinForms. It's also not AppDomain.CurrentDomain.UnhandledException. But I find it - GLib.ExceptionManager.UnhandledException.

Not this way.

As Christian has said there is an event you can subscribe for unhanded exceptions. Very cunningly they call it, UnhandledException. However, if you are trying to catch an exception from a button click it should be handled at the lowest possible level, not at the application level.

only two letters away from being an asset

Definitely I would handle it within the click event itself, that way it will definately catch the exception, as mark said you should always try to catch it at the lowest possible level, but never at the application level.

how to make simulation softwares

It's not for handle expected exceptions. It's need for log unhandled exceptions.

can anybody help me on how to get started with making a simulation software?
I want to make a 8085 simulator.
please tell me the following points
1.IS C# fully capable of doing it
2.what else do i need?

Luc Pattyn13-Sep-09 11:48

13-Sep-09 11:48

Hi
1. yes
2. some 10,000 lines of code; all the 8085 documentation you can get

Are you sure it is 8085 you want? that's a very old (and simple) CPU
Do you need logic simulation only? or has it to be cycle accurate too?
What kind of I/O will you need to handle? (CPU and memory is easy, I/O depends on functionality).
The hardest part is getting the condition flags (zero, overflow, ...) correct for each instruction.

Is performance relevant? Any idea what speed you want? Depending on previous answers, your slow-down will be
1000 or more.
And how do you plan to test your code?
Make sure you have sufficient programming experience and know the language well before you attempt this!

First of all Thank you very much! Your idea is helpful.
I've decided to do 8085 CPU because it is relatively simple.
If possible I will try to make it fully functional.
The user must be able to execute step by step and see the registers and active memory contents.
Performance is greatly relevant, and the speed also has to be good.
Can you please tell me Something about how to test the code?
Can I find helpful books and sites for this project?

thank you Thumbs Up | :thumbsup:

- all instructions?
- instruction timing?
- cycle accurate?
- what input/output devices?
- how is code entered?

- good architectural design
- test with actual programs (e.g. C-code + cross-compiler)

- don't know, except for manufacturers documentation
- I did dozens of simulators, running my own operating systems and applications

How you doing?
thank you very much once again.
You wrote an excellent article for the lean-and-mean competition;
I'm comp Engg student,I'm trying to do my final year project, that simulator is going to be my project.
I hope I would get more knowledge on it.
If you have time,Can you please give me some more information.
I'm designing the interface on C# windows application.I want to start from the instruction execution part by allowing the user to write the code and run it just like emu8086.
Can you help?
hope to hear from you soon.

Luc Pattyn15-Sep-09 4:30

15-Sep-09 4:30

Thanks.

I don't know emu8086, and I don't think it handles 8085.

Why do you choose 8085, it is terribly old; why not choose a microprocessor that is still in use?
I would consider one of the Microchip PICs for instance; say a 16F84.
Whatever you choose, make sure you have the development tools for it.

FYI: I've done 6502, all kinds of 6800 and 68000, some PICs, 8048, x86, NIOS2 and more.
The NIOS2 one was done in pure C# and ran one million instructions per second; it executed my own operating system and some multithreaded test applications.

I give advice and answer specific questions. Generally I don't provide code.

Make sure you have answers to the questions I asked you before you commit.
Good luck with your project.

Since you first tell me about 8085 or 8086 matter I read alot and come into a conclusion that to begin working on 8086.

Now I've divided the project into phases.
my first phase is dealing with Execution of instructions. for this I need The user to write codes on multiline textbox and try to execuit the code by pressing run.
the problem startes here,I can't access Individual lines of code perfectly. Does it works this way?

Luc Pattyn15-Sep-09 5:41

Normally a simulator is not involved in creating code, it should get its code from a file, that is why I warned you you would need the development tools, so they help you in creating some kind of EXE file which your simulator then can load in simulated memory for execution.

If you expect your user to enter some code in a textbox, it won't be much of a program, only a few lines, and you will never be able to prove your simulator works correctly as you won't test all instructions by entering them by hand, will you?
