Remember that there is a DataRowCollection Class that wou can instantiate and compare in a cyclic manner with the previous instance.

Does anyone know how to or know of a tutorial to programatically zip a file?
I have a series of images that need to be able to be placed in a zip file so the user can download it to their hard drive. Manually zipping these files won't work in this situation.
Thanks.

Hi,
I downloaded the library. But there are so many classes and interfaces, I got confused how to start using this library to create a zip file and simply add files into that. also how to unzip a single zip file.
Is there any snippet available about the usage of this library ?

Probably on the #Develop website is the best bet

Hello,
How can I change the background colour of my WebBrowser control that I am hosting in the windows form? Is there a way of doing it?
Thank you.

Hello
For what I know the background color of the webbrowser control is the color of the background of the page that is currently displayed. Why would you want to change that?

HELLO,
I think you can simple update the DocumentText property everytime the documentTExt is changed.
Update the DocumentText like ,
weBrowser1.DocumentText =
If the webBrowser is loaded with a navigated webpage, then you may try to use Regex to set the body bgcolor within DocumentText.
I am sure you wll find better solution than my solution  But thats what I am doing in my appliation to change background color of my webbrowser.

Hi,
Is it possible to cancel Form Colosing in the Form Closing Event ?
I have background worker in my form and when user try to close a form where a background worker is still busy, I want to let the user know that,
"A background process is still busy, Try closing Later" -- And then Return the method without closing the form.
|
|
|
|
|
The onclose event has a CancelEventArgs prameter e.
set e.Cancel to true.
|
|
|
|
|
Thanks wheelerbarry,
As far I know, these onClose, onLoad type events are protected members and I will have to override this methods right ? Is not it possible simply using e.Cancel within FormClosing event handler ?

Yes it is! It's even the standard practice.
Yet better make it the other way around. You shouldn't make the user wait for the thread. The thread should wait the user. Make your background worker a Background thread that will b terminated once the application is closed so that the use won't get frustrated waiting for something they don't even see or know when will it finish.

What happens when I execute Application.Exit() if a background worker is still busy in that application ? I assume that, all threads and background workers are immediately stopped and the application isexited. Is not that right ?
The same question is for Application's main parent form closing. If the user simply click the cross button of top right corner of the Main Parent Window to close, will the threads and background workers are terminated immediately or they keep on running invisible ?

You'd be surprised if I tell you that i've never used those BackgroundWorkers!! I always use good old fashioned multithreading. I even don't know why they made this clas?!!
Anyway, if a thread is made Foreground then it will keep running invisible and your applicatoin won't really exit. You can check that out using the task manager. But if you make that thread background by setting Thread.IsBackground = true, then it will close once all foreground threads are close and the process won't wait for that thread to finish. I don't know about BackgroundWorker class if it's really background, but it would take a small test to find out -I'm currently too lazy to lookup MSDN;P-

I feel more comfortable using Google than MSDN to search for a C# solution.

Hi, I want to control access to files stored in a specified location using visual c# 2003. The file security features are only available in visual c# 2005.
Thanks

Are you sure? I don't think that is true. File Security is part of the Operating System, not .NET.

Hi,
Can I have your recommendations please on a good but inexpensive obfuscator to use for my soon to be released killer app When I say good - is a more thorough than b. Is the extra cost of c worth it when a will deter most ammature hackers etc.
I've looked into the archives and read a lot of comments on the subject but no real suggestions or comments based on personal experience/usage seem to have been made.

I've read good things about the following product, but have no personal Exp with it:

If you have something worth protecting then go here[^]

There is much hype about them but there is only one thing a killer app can really protect against and that is killer data structures and algorithms. Everything else can usually be derived from the app itself.
Sure a non-obfuscated app can be easily decompiled and repackaged but, last time I checked, that was a felony. Bad things happen to bad people.
My advice: If you have a killer app build a killer business model to surround it and you will be rich.
(Of course I will probably get low votes on this so let me say this: some obfuscators are cheap and it is ok to obfuscate. Just don't worry about it too much)
