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!!!

Thanks - I'll have a look. Does it come with source ?

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.

Sure, try these:

Environment.OSVersion.Version.ToString();

Hi,
The following should help you:
System.Environment.OSVersion.Platform,
System.Environment.OSVersion.Version
If you want the logged on user, then
There are bunch of other methods and properties in System.Environment that should elicit your interest in the above regard.

Hello,
I have made a database - SQL Server 2000 - to handle some stuff e.g. contacts, orders, etc.
I tried to normalize the database the best that I could and this lead to a lot of tables. For example since the contacts are worldwide, there are 3 tables that each one, hierarchically store country, province, county.
Finally in the table where each contact is contained i just store the ID of the county, and the province and stare would be retrived through the realationships.
Ok, this is just an example, the thing is much more hierarchical and normalized.
I would like to know how can I practically retrive, use, and update data from this database using ADO.NET? I mean, I am a bit confused.
Is there a simple way or is it going to be a mess all do be done from zero?
Thanks for any help.
Edoardo

I don't think there is a quick answer to your question, but I'd be willing to dialog with you about it for a while and share with you my techniques dealing with normalized databases. Beware though, I don't use a lot of what ADO.NET provides--instead, I tend to code client or server side SQL directly, depending on the requirements.
That said, it seems that ADO.NET can handle relationships between tables, as long as you tell it what those relationships are, and it should handle updating records correctly (I think. I've never tried this). [personal comment--I've never used this feature because I think it is really stupid to duplicate the database model in the code: what if you want to change the DB model?]
Also, have you set up foreign keys so that deletes and updates are cascaded? This can save you a lot of programming time.
Also, if you can provide some specific examples of what you are trying to do, it might be easier to consider what the different solutions are and their benefits/drawbacks.
Finally, hierarchical architectures are a PITA. Since you seem to only have a three level hierarchy, I think the best thing to do is to deal with the individual insert/update/delete/select statements. I had to create a model for a satellite company once that allowed basically infinite drill down in a hierarchy. Argh.

How can Create a binary registry entry (Binary Value) to save a login or access password?
Jassim Rahma
|
|
|
|

Your problem is writing to registry or you have problem to change password to binary value?
If your problem is first one,search this site,you can find an article about it.If it is second one you can write a function that get password string and return it like this:
public static byte[] EncryptPassword(string password)
{
UnicodeEncoding encoding = new UnicodeEncoding();
byte[] hashBytes = encoding.GetBytes( password );
SHA1 sha1 = new SHA1CryptoServiceProvider();
byte[] cryptPassword = sha1.ComputeHash ( hashBytes );
return cryptPassword;
}
