The problem is that every time you call AssignColor, a new Random object is generated and is seeded using the current system time. This happens EVERY time you call AssignColor; so what happens is you call it the first time, it seeds the RNG (Random Number Generator), gets a value, then goes to the next block, seeds the RNG (using the same system time because not enough time has elapsed, spits out the same number, etc...
Solution: Instead of creating more than one Random object, make the Random object a static member of the BlockClass class; and use it like so...
class BlockClass {
static Random r = new Random();
public void AssignColor()
{
switch(BlockClass.r.Next(4))
{
}
}
}Doing so ensures that only one instance of the Random class is generated so you can actually pull more than one number out of it.

One approach you might try is this:
use a wide span of numbers going from something like 0.00001 --> 0.99999
then when you get a next number, multiply this by your max number + 1
and scrunch it to an integer to lop off the extra decimal places.
By applying this approach you should give your random generation a wide enough spread that it jumps all over the place. If you are just doing a Random from 1-->4 you do not have a very wide spread to allow for wide swings in changes. You would do a multiply of max+1 since your number never reaches 1.0 and integer math should keep the (max+1)*rnd(next) actually exceeding the max value.

Not really sure where to ask this one, so I'll clutter the boards up here...
Is there a way to tell a TabPage on the TabbedGroup control to close or hide? I want to be able to show/hide or create/destroy the TabPages according to user selections on a menu (ie, uncheck a menu item and the corresponding window goes away). Show/hide would be ideal, but the windows don't seem to be responding to Hide() calls once created. Has anyone run into this issue?
I get all the functionality I need out of this set of controls (which are top notch, BTW)...just this one final hurdle to overcome!

I'm ready to throw my PC through the wall. I have two panel controls in a Windows Forms application that I'm writing. Both are set to full docking, and placed on the right side of a splitter bar, so the share the same space, but only 1 is visible at a time. Docking is set to full for both. My problem is that the Visible property is NOT setting for one of the panels. As I step through my code, calling Panel.Visible = True does nothing; looking at the property in the debugger shows that it is STILL false, and no exception is thrown.
Any ideas?
Thanks in advance.

Wow. I've never seen that problem before. Can you post some code?

Well, it's in theory anyways, very simple:
private void trvHierarchy_AfterSelect(object sender, System.Windows.Forms.TreeViewEventArgs e)
{
if (((string)e.Node.Tag).IndexOf("Folder:") >= 0)
{
if (pnlHoursList.Visible = true)
{
CreateSummary();
pnlHoursList.Visible = false;
pnlUsageSummary.Visible = true;
}
else
{
pnlHoursList.Visible = true;
pnlUsageSummary.Visible = false;
}
}
}
CreateSummary just fills a listview on pnlUsageSummary. I can show or hide pnlUsageSummary, but I can't seem to set pnlHoursList's visibilty.

1) You can simplify your code by doing this:
if ((((string)e.Node.Tag).IndexOf("Folder:") >= 0) && (pnlHoursList.Visible == true))
{
CreateSummary();
pnlHoursList.Visible = false;
pnlUsageSummary.Visible = true;
}
else
{
pnlHoursList.Visible = true;
pnlUsageSummary.Visible = false;
}
And then, what you should probably do is set the visibility of pnlUsageSummary to false before you set the other to true...

The first question is more to the IDE than anything else. I noticed that you can add all types of files into a project, including XML and XSLT files. Is there any advantage to this and how do I programmatically access these files. For example, if I have three XSLT files in my project, how do I get at these to execute transforms against the XML file passed to me?
Second XML question: Once I have created an XMLDocument file, I want to generate a schema for the file automatically. I cannot find a method or docs on doing this. Any help in this direction would be great.

If you paste text into a file it knows is XML, it will HTML encode it. This is sometimes good, sometimes a pain.

I dunno how to load them from resources, I presume you still need to load from disk, but having them in the project makes them easy to get to.

I wrote an XML wrapper in C# for WDJ magazine ( it's not been printed yet ), and I looked into this. I thought you need to do it yourself, but I'm learning ADO at the moment, and a dataset can create a schema for you in XSD format, and I believe you can fill a DataSet from XML, so that might be an answer. Any auto generated schema would of necessity be imperfect, unless all your nodes always appear, and always appear the same number of times.

Yum - thanks. I have the issue, but had not noticed this, which means without your assistance, I never would have. I'll dig it up tonight.

I know that it is possible to generate schemas from XML -- after all XMLSpy does this programmatically. So it can be done. The question is: how is it done within the Framework?
Anyway, you've helped me some. Thanks.

I got a response over on GotDotNet...
there is an XML --> XSD Inference tool available there.
The location of the tool is http://www.gotdotnet.com/team/xmltools/[^]
It generates a very verbose XSD file. Which may be of use for most people. We just happen to need a more compressed schema file. So I guess we are stuck with manually creating schemas from XMLSpy for now!
Thanks for your help and maybe this link can be of help to you!!!

It is Microsoft code. It's free, but it is also without source.

Hey yccheok,
How about System.Diagnostics.Process.Start(filename)?
That should trigger your default browser to open the filename which is an html document right?

I want to login to Active directory with DirectoryEntry,I use this code but I always get unknown username or password:
de.Path = "LDAP://mazy/rootDSE ,DC=mfa";
de.Username = @"Mazdak";
de.Password = "mypass";
"mazy" is my domaincontroller and mfa is my domain.I change the Path in many ways but I get the same results.
