There is an article

that talks about loading and unloading plugins at runtime. Might be of some help.

VS .NET on Win2000

I would like ot install on my computer (128RAM, 450MHz) Windows 2000, because I hope I'll get a better performance with VS .NET, than I get under WIndowsXP. (I do not plan an upgrade until January '03)
Do I make a right guess??

Here my prob is how to install Windows 2000 without do destroy WinXP? Any ideas are appreciated!

Thank you!

Yes, because Windows XP will eat a larger part of that 128Mb RAM than Win2K will, but I'm not sure you'll get quite the benefit you're hoping for.

You need a completely spare partition, usually the primary partition of a secondary drive (not even sure if it's possible otherwise). Reboot from the CD and follow the instructions, being very careful not to format or install on the wrong drive. You should end up with a machine that asks you on startup which version of Windows you want to load.

Just as a bit of free advice - don't try to hook the software from XP into 2K, it's much safer to have two copies of everything.

Dual boot machines, as you may have guessed by now, can be very heavy on disk space; you might find it a lot cheaper just to buy a couple of 256Mb RAM chips. RAM is surprisingly cheap nowadays.

I have too much free space on my HDD, so its going to be cheaper than another peace of RAM I also would like to be able to use Win2000 too, so installing Win2000 isn't that bad.

BTW. What about if I want to install win from HDD (I remember the first time when I did it from the CD, it took me about 2hrs Wink | ;)

Should this make a difference?

I find that if u install from HDD, WIn2k copy the files to a temp location, however installing from a booted win2k cd wont copy the files, it will just read straight from the CD.

That's fair enough. If you work it properly, you can do all sorts of cool things like being able to link your Outlook files to the same place, etc. Useful if you're going to be doing this long-term. I ran 2K/ME dual-boot for over a year.

Haven't found a reason yet to have XP and 2K dual boot but I'm running 738Mb of memory, so XP is fine. If I only had 128 I'd be doing the same thing you are Smile | :)

As leppie said, this isn't always a good idea and to be honest it probably wouldn't save you that much time unless you're running a slow CD ROM drive (8x or less).

Installing an OS is never a quick job.

One other piece of advice... make sure you have Win2K versions of all your hardware drivers before you start Smile | :)

Hi

I already replied to this earlier !!! Mad | :mad:

You need to install WIn2000 on a diferent partition, as a fresh install, hopefully it wont overwrite the XP loader (it is practically the same). If it does, just start the install of XP again, till the 1st reboot, then the loader will be restored, then quit the install, iow select old XP menu item.

Finally, remove the XP setup entry from the boot.ini file.

Hope this help

Concerning Event Handling

Hey all - I was asked an interesting question today which stumped me. I was using the ASP.NET Custom Validation control to do custom validation. You use the EventArgs (I forget the name of the derived class) to specify an Isvalid property for whether your custom validation is successful or not successful.
But how is this information returned to the caller, I was asked, since the EventArgs object is passed Byval? It's a copy that is local to the procedure, correct?

cout << "dav1d\n";

a reference type passed "ByVal" as opposed to "ByRef" or "ref" in c#, simply means that you cannot change the reference, not that the object is copied.

I really would like to know more about aspect oriented programming. The only refernce to it at msdn is an article that touches too much on com and atl.
Does anyone have some material on this subject that is not so much into com?

cast string to guid

Shaun Wilde12-Sep-02 5:47

Shaun Wilde

12-Sep-02 5:47

How

most types such as int have a Parse method but Guid does not.

currently I do this

<br />
		static public Guid Parse(string input)<br />
		{<br />
			Guid guid = new Guid();<br />
			guid = (Guid)TypeDescriptor.GetConverter(guid).ConvertFromString(input);<br />
			return guid;<br />
		}<br />

but it seems very long winded.

doh! - I never noticed that Guid took a string as a constuctor argument - I did think it was daft what I had to do and knew I was missing something

I don't have the VS.NET on this computer right now but I think you have to set the label control to have multiply lines...

No multiline property for a label. I think your ref is for a text box. Did you try putting a newline in the string to see what happens?

label.Text = "Text" + Environment.NewLine + "More Text";

Not sure if that will work.
