(However, a few clients they have their own servers with SQL 2005.) So we have local installs of SQL 2005 Express for development on Windows XP SP3 boxes (which don't allow SQL 2000 Enterprise installations).
We often need to copy SQL 2000 databases to SQL 2005 instances. In the past, we have used the SQL Publishing tool (also mentioned [here][1]). However, one of our databases is so big that using that tool fails as it creates SQL scripts that get too large for Management Studio to handle them properly. Besides, it takes too long... :)
We would use the Copy Database Wizard included with SQL 2005, but our development machines run SQL 2005 Express which don't included SQL Server Agent, which is required for Copy Database Wizard to work. So, I guess our solution will be to upgrade our development installs with the full version of SQL 2005 (we have an MSDN subscription of course).
I was wondering what other solutions, if any, work well for you guys? (Besides complaining to the bosses to upgrade our production servers to 2005 or even 2008--which I've already tried.)

I've read the other thread about [Enumerable.SequenceEqual][1], but it's not exactly what I'm looking for.
In my case, two collections would be equal if they both contain the same items (no matter the order).
Example:
collection1 = {1, 2, 3, 4};
collection2 = {2, 4, 1, 3};
collection1 == collection2; // true
What I usually do is to loop through each item of one collection and see if it exists in the other collection, then loop through each item of the other collection and see if it exists in the first collection. (I start by comparing the lengths).
if (collection1.Count != collection2.Count)
return false; // the collections are not equal
foreach (Item item in collection1)
{
if (!collection2.Contains(item))
return false; // the collections are not equal
}
foreach (Item item in collection2)
{
if (!collection1.Contains(item))
return false; // the collections are not equal
}
return true; // the collections are equal
However, this is not entirely correct, and it's probably not the most efficient way to do compare two collections for equality.
An example I can think of that would be wrong is:
collection1 = {1, 2, 3, 3, 4}
collection2 = {1, 2, 2, 3, 4}
Which would be equal with my implementation. Should I just count the number of times each item is found and make sure the counts are equal in both collections?

The examples are in some sort of C# (let's call it pseudo-C#), but give your answer in whatever language you wish, it does not matter.

My goal is to simulate list markers using generated content, so as to get e.g. continuation of the counters from list to list in pure CSS. So the HTML is like this:
<ol>
<li>The<li>
<li>quick</li>
<li>brown</li>
</ol>
<ol>
<li>fox</li>
<li>jumped</li>
<li>over</li>
</ol>
and the CSS, which I *think* is correct according to <a href="http://www.w3.org/TR/CSS2/generate.html#markers">the spec</a>, is like this:
html { counter-reset: myCounter; }
li { counter-increment: myCounter; }

So, does anyone know if markers are *supposed* to work? Quirksmode.org isn't being its usual helpful self in this regard :(. | css | crossbrowser | null | null | null | null | open | Does "display: marker" work in any current browsers, and if so, how?
===
I can't be sure if my code is sucking, or if it's just that the browsers haven't caught up with the spec yet.
My goal is to simulate list markers using generated content, so as to get e.g. continuation of the counters from list to list in pure CSS. So the HTML is like this:
<ol>
<li>The<li>
<li>quick</li>
<li>brown</li>
</ol>
<ol>
<li>fox</li>
<li>jumped</li>
<li>over</li>
</ol>
and the CSS, which I *think* is correct according to <a href="http://www.w3.org/TR/CSS2/generate.html#markers">the spec</a>, is like this:
html { counter-reset: myCounter; }
li { counter-increment: myCounter; }
li:before { content: counter(myCounter)". "; display: marker; width: 5em; text-align: right; marker-offset: 1em; }
But this doesn't seem to generate markers, in either FF3, Chrome, or IE8 beta 2, and if I recall correctly not Opera either (although I've since uninstalled Opera).

However I've found that this gives a different definition of "% of CPU Utilization" than I'd like - according to the manpages for ps, `pcpu` is defined as:

In other words, `pcpu` gives me the % CPU utilization for the process for the *lifetime* of the process.
Since I want to take a sample every X seconds, I'd like to be collecting the CPU utilization of the process at the current time only - similar to what `top` would give me

**Platform**
1. ASP.NET / VB.NET / .NET 2.0
2. IIS 6
3. IE6 (primarily), with some IE7; Firefox not necessary, but useful
*Allowed 3rd Party Options*
1. Flash
2. ActiveX (would like to avoid)
3. Java (would like to avoid)
**Current Attempts**
*Gmail Style*: You can use javascript to add new Upload elements (input type='file'), then upload them all at once with the click of a button. This works, but still requires a lot of clicks. (I was able to use an invisible ActiveX control to detect things like File Size, which would be useful.)
*Flash Uploader*: I discovered a couple of Flash Upload controls that use a 1x1 flash file to act as the uploader, callable by javascript. (One such control is [FancyUpload][1], another is [Dojo's Multiple File Uploader][2], yet another is one by [darick_c at CodeProject][3].) These excited me, but I quickly ran into two issues:
1. Flash 10 will break the functionality that is used to call the multiple file upload dialogue box. The workaround is to use a transparent flash frame, or just use a flash button to call the dialogue box. That's not a huge deal.
2. The integrated windows authentication used on our intranet is not used when the Flash file attempts to upload the files, prompting the user for credentials. The workaround for this is to use cookieless sessions, which would be a nightmare for our project due to several other reasons.
*Java Uploader*: I noticed several Java-based multiple-file uploaders, but most of the appear to cost money. If I found one that worked really well, I could arrange to purchase it. I'd just rather not. I also don't like the look of most of them. I liked FancyUpload because it interacted with html/javascript so that I could easily style and manage it any way I want.
*ActiveX Uploader*: I found [an ActiveX solution][4] as well. It appears that ActiveX will work. I would just write my own instead of buying that one. This will be my last resort, I think.
**Resolution**
I would love to be able to use something like FancyUpload. If I can just get by the credentials prompt some way, it would be perfect. But, from my research, it appears that the only real workaround is cookieless sessions, which I just can't do.
So, the question is: Is there a way to resolve the issues presented above OR is there a different solution that I have not listed which accomplishes the same goal?

===
I have a couple of solutions, but none of them work perfectly.
**Platform**
1. ASP.NET / VB.NET / .NET 2.0
2. IIS 6
3. IE6 (primarily), with some IE7; Firefox not necessary, but useful
*Allowed 3rd Party Options*
1. Flash
2. ActiveX (would like to avoid)
3. Java (would like to avoid)
**Current Attempts**
*Gmail Style*: You can use javascript to add new Upload elements (input type='file'), then upload them all at once with the click of a button. This works, but still requires a lot of clicks. (I was able to use an invisible ActiveX control to detect things like File Size, which would be useful.)
*Flash Uploader*: I discovered a couple of Flash Upload controls that use a 1x1 flash file to act as the uploader, callable by javascript. (One such control is [FancyUpload][1], another is [Dojo's Multiple File Uploader][2], yet another is one by [darick_c at CodeProject][3].) These excited me, but I quickly ran into two issues:
1. Flash 10 will break the functionality that is used to call the multiple file upload dialogue box. The workaround is to use a transparent flash frame, or just use a flash button to call the dialogue box. That's not a huge deal.
2. The integrated windows authentication used on our intranet is not used when the Flash file attempts to upload the files, prompting the user for credentials. The workaround for this is to use cookieless sessions, which would be a nightmare for our project due to several other reasons.
*Java Uploader*: I noticed several Java-based multiple-file uploaders, but most of the appear to cost money. If I found one that worked really well, I could arrange to purchase it. I'd just rather not. I also don't like the look of most of them. I liked FancyUpload because it interacted with html/javascript so that I could easily style and manage it any way I want.
*ActiveX Uploader*: I found [an ActiveX solution][4] as well. It appears that ActiveX will work. I would just write my own instead of buying that one. This will be my last resort, I think.
**Resolution**
I would love to be able to use something like FancyUpload. If I can just get by the credentials prompt some way, it would be perfect. But, from my research, it appears that the only real workaround is cookieless sessions, which I just can't do.
So, the question is: Is there a way to resolve the issues presented above OR is there a different solution that I have not listed which accomplishes the same goal?

The control will allow a developer to point it at a "username" TextBox and it will provide an indication of whether or not the username is available. Like [this example][1], but without the clunky UpdatePanel.
One design decision that's giving me headaches is whether to inherit from **ScriptControl** or **BaseValidator**.
By implementing it as a **ScriptControl**, I can make the client side portion easier to deal with and easily localize it with a resx.
However, I want to make sure that the validator functions properly with respect to Page.IsValid. The only way I know to do this is to override **BaseValidator** and implement EvaluateIsValid().
So, my question is, how would you suggest structuring this control? Is inheriting from BaseValidator the best (only) way to get the validator part right, or can I do that in some other way?

I'm trying to think of all potential security holes I need to plug, one of which is a user pasting in Javascript:
<script type="text/javascript">
// Do some nasty stuff
</script>
Now I know I can strip this out at the server end, before saving it and/or serving it back, but I'm worried about the possibility of someone being able to paste some script in and run it there and then, without even sending it back to the server for processing.
Am I worrying over nothing?
Any advice would be great, couldn't find much searching Google.

Well, I fire up my handy VM with my app installed, and what do we get... AAAAGH!!! MASSIVE UI FAIL!
Everything's all jumbled: some containers aren't big enough for their text; some controls that were positioned "next to each other" are now all squished together/spread apart; some buttons aren't tall enough; my `ListView` columns aren't wide enough... eeek.
It sounds like a completely different approach is in order. My previous one was basically using the VS2008 Windows Forms designer to create, I guess, a pixel-based layout. I can see that if I were to stick with Windows Forms, `FlowLayoutPanel`s would be helpful, although I've found them rather inflexible in the past. They also don't solve the problem where the containers (e.g. the form itself) aren't big enough; presumably there's a way to do that? Maybe that `AutoSize` property?
This might also be a sign that it's time to jump ship to WPF; I'm under the impression that it's specifically designed for this kind of thing.
The basic issue seems to come down to these:
* If I were to stick with Windows Forms, what are all the tricks to achieving a font-size-independent layout that can survive the user setting his fonts large, or setting the display to 120 DPI?
* Does WPF have significant advantages here, and if so, can you try to convince me that it's worth the switch?

**Details**
I've a standard CDR call detail record, that contains among others:
* calldate (timedate of each call start
* duration (int, seconds of call duration)
* channel (a string)
What I need to come up with is some sort of analysys of simultaneus calls on each second, for a given timedate period. For example, a graph of simultaneous calls we had yesterday.
(The problem is the same if we have visitors logs with duration on a website and wish to obtain simultaneous clients for a group of web-pages)
What would your algoritm be?
I can iterate over records in the given period, and fill an array, where each bucket of the array corresponds to 1 second in the overall period. This works and seems to be fast, but if the timeperiod is big (say..1 year), I would need lots of memory (3600x24x365x4 bytes ~ 120MB aprox).
This is for a web-based, interactive app, so my memory footprint should be small enough.
