This is the correct behavior. The Object Collection Editor is not allowing the user to choose which array the property should be set to, but, rather, is allowing the user to modify the contents of the array. The objects in the array are being edited.

This might be due to the fact that the property is an array type. If you were to use an ArrayList instead of an array, does that fix the problem? I imagine it would.

I the days of COM we had reference counting, which i beleive probably still exists within .Net in some form or other otherwise the gargabe collector wouldn't be able to do it's job.
I basically want to code a simple but semi intelligent cache, where upon an object being added to the cache it remains there whilst there's more than one reference to it. One of the references being the cach of course. But when only the cache has a reference and maintains that single reference for around say 5 mins, after 5 mins it unloads it. I'd like the cache to manage this without the business object having to know anything about the cache, otherwise I could probably place a call within the business objects dispose() to decrement a reference count of some form.
The reason for this is to create a smart datalayer and reduce the number of trips to the database for certain business objects.
Or is there another way????

It's simple !
Call "GetFiles" for each file type. 
<br />
string folder = "c:\\";<br />
ArrayList list = new ArrayList();<br />
list.AddRange(Directory.GetFiles(folder, "*.html"));<br />
list.AddRange(Directory.GetFiles(folder, "*.doc"));<br />
list.AddRange(Directory.GetFiles(folder, "*.txt"));<br />
string[] files = (string[])list.ToArray(typeof(string));<br />
Best regards, Alexey.

Creating a DataSet at runtime or at "design time" (which really just means that VS writes the code for you - it's still created at runtime) has absolutely no relevance as to whether an application can connect to a database. My guess is that whatever you're doing at design-time is causing your db connection information to be generated as well. If you want a

then just check out the code that Visual Studio writes for you after you drag and drop a DataSet onto the Form.
Please, don't ever ask for a full source code example. We have our own jobs.

You did not provide any information pertaining to the hosting process and context for the C# code and the scripting engine. Without that I don't know if anyone would be able to help.

foreach (string name in mylist)
{
Page.RegisterArrayDeclaration("listname", name);
} This will emit the following:
var listname = new Array('a','b','c','d',....);

I have the following callback function which I am using to update a progress bar. The only problem is, when I change the value of the progress bar, the bar doesnt change It just shoots to 100 when it is done. I have tried using Application.DoEvents(); .
private Int32 CopyInProgress(uint TotalFileSize, uint BytesTransfered, uint StreamSize, uint StreamBytesTransfered, uint DwStreamNumber, long dwCallbackReason, long hSourceFile, long hDestinationFile, long lpData)
{
float t = TotalFileSize;
float bt = StreamSize;
int nPercent = (int)(bt/t)* 100;
percentComp.Text = nPercent.ToString() + "%";
progressBar.Value = nPercent;
Application.DoEvents();
return PROGRESS_CONTINUE;
}
Any ideas why this is happening?

Yup, I got an idea.
You are converting a float (bt/t) into an int...then multiplying it by 100.
By definition, when you make it an int in this manner the answer can only be 0 or 100 and nothing in between.
try changing it to:
int nPercent = (int)(bt/t*100);

Nicely spotted! I was trying to find a reason why the message couldn't have reached the control. Tuh!

Not a problem. Even a crusty old C programmer gets to get one right once in a while.
The rest of the time I'm generally walking around C# and .NET like a complete idiot because so many of the rules have been changed that there's not a lot of advantage to having programmed for 20+ years...LOL.
