I have a question about how to do the following and the pros and cons about doing either.
I have a class that I want to be able to log some activities, such as "function has been called". I could define an event call CurrentInfo(byval infoType as Integer,byval message as String), and then let the logger subscribe to the event and do whatever, or I can pass a logger to the class and whenever I wanted to log something I will call "logger.log(infoType, message)"
Which appoarch is better?
Thanks

That depends on your definition of "better". I'm using an ILogger, sometimes writing to console, sometimes to the eventlog, and a null-implementation of the ILogger (doesn't log anything). The logger-object is static, so it doesn't need to be passed as a parameter to each and every method.
Might not be the "best" approach, but works for me

Thanks for the answer. I know it's relative and is different from one to the other scenarios. I found that, as you said, if I don't need a logger from time to time I will have to pass a null logger to the class. Yet event can be hooked up dynamically as needed.....I really want to know is there a big PLUS to use logger instead of using events. Thanks

You don't have to, you could also test whether the user has a boolean checked to control if the app logs or not. The null-logger a common pattern because it's convenient.

Requires less code. How would you do it with events? Raising an event for everything that you might want to log? Can you post an example?

I was woundering if anyone knows any codes for a Rehash and Resign Program? It might have.... 2 buttons or 3 if it will have rehash and resign as one button then rehash as a button and resign as a button.
it should have atleast 5 textboxes ....

You seem to want to modify a saved game then re-hash it?
No, you're not going to get any help with that here. I think the reasons are quite obvious.

Thanks Anyways Figured i would still give it a try to ask about it on here.
I've Figured it out after a few hours plus using my Visual Basic Guides as help but the code words on First use then Gives me an Error .... so i set the Program to Restart so as to NOT get the error but if anyone can help with THAT it would be GREAT  Thanks anyone who can help if you need that part of the Code just ask and ill give.

OK. What guides are you talking about??
Member 8768189 wrote: but the code words on First use then Gives me an Error
Still not a clue what you're talking about.
Member 8768189 wrote: so i set the Program to Restart
Since there's no property or method to "restart" an application, we STILL don't have a clue what you're talking about.
Member 8768189 wrote: so as to NOT get the error
You never said WHAT error you got, not what the code looked like, so, uhhhh, yeah, more of the same "we don't have a clue what your talking about"...
Member 8768189 wrote: Im NOT going to Delete that part of Code to NOT get the errors....
WHAT code?? That does WHAT?? Again, you haven't provided us the smallest of clues to figure out what you're talking about...

im sorry to all the people i confused. i was working on that Rehash and Resign Program for days and was annoyed at the one error i kept getting no matter what i did. i figured it out after reading ALOT of microsoft Visual Basic Guides and other Random guides like those and VB Code cook books ... well i used bits of codes here n there from a few different guides and some of my own codes and got my rehash and resign program .
thank you all for being here even when i was stupid about how i worded things and i was not online alot which im also sorry for... its just im stuck with dial-up when i do get online 90% of the time....
the results of my program are great but it can be better. if anyone has made a program similar to mine you might wanna check it out when i post it.
To clear up the title confusion i ment to put "Rehash and Resign Program" and what it does is "Rehash and Resign Xbox 360 game save files" ....
ill post the old code on here later (the code i got stuck on with errors) in case anyone would like to play with it.

Without seeing your code and the data (both sent and received), nobody will be able to guess what is happening. Please see here[^] for hints on writing a question.

Hello again,
I was wondering if you could create another "imaginary" mouse or a second cursor, and make it click somewhere.
Simple Thanks and Regards,

Yes you can use SendInput[^] to simulate mouse operations. Controlling an app with it is quite tricky as many things may change over time: the relative position of Controls on a Form, the reaction speed of an app, etc. You have to program very defensively when using it, so please make sure the right window gets activated before clicking around. And then there are unforeseen situations (client changes screen resolution or default font size, and everything moves around; or he changes the system language and all texts change); and there are unforeseen events, where an app assumes a human user and suddenly throws a warning/error modal dialog at him, which your automation code doesn't expect and doesn't know how to handle.
As a result, it is much better to have an API for the app you want to control; or to programmatically create a document, then open it in Word/WordPad/etc for the user to read, adapt, and process.

Hello,
I am wondering that if you could have 2 executables or programs, one accessing another one's controls, like my Vb.NET program pressing a button on notepad.exe, or menus.

Yup, that's possible, the collection of those techniques would be called "interprocess communication".
You can take a pick between TCP/IP, (Named) Pipes, SendKeys, Memory mapped files and many more. A good CodeProject-article would be ".NET Remoting in Simple English (Really, it's that simple)[^]".

not cool to see the same question twice.

Those concepts will only work if he has access to both programs' code. If you are trying to control a program you did not create or cannot modify, you will need to use API calls such as "FindWindow"/"FindWindowEx" to locate the window and child control (also considered a "window"). You can use programs like spy++ or winspector spy to figure out the class/caption of the windows and controls. Once you have the handle (intptr) to the control, you can use other API calls to send key presses and/or mouse clicks. You'll have to google those, tho.
Hope that helps!

If you need to build your softphone in VB.NET you might try out the following sample program: www.voip-sip-sdk.com/p_179-windows-forms-softphone-vb-net-voip.html It’s based on an sdk which is written in .Net and therefore insures flexibility including even further developments. I don’t want to advertise just share my good experiences.
