i am creating a databound treeview but i am having trouble with my properties.
I created a collection to hold the labels. and i added to the designer.
I can create the labes, however, i do not know how can i save it;

public class MyTreeColumns // this is my class containing the string label
public class MyTreeColumnsCollection:CollectionBase // this is my collection of labels with methods for indexing, Add, Indexof, insert, remove, and contains.

in the dataTreeView class I added:
MyTreeColumnsCollection _objects = new MyTreeColumnsCollection();

[Browsable(true)]
public MyTreeColumnsCollection TreeColumns
{
get
{
return _objects;
}
set
{
_objects = value;
}
}

what i am missing?
thank you

I think you have to mark your classes as [Serializable].

Depending on your object structure you might have to implement the ISerializable and IDeserializationCallback interfaces. (Like Hashtable does)

Its possible to use the webbrowser control as an OLE container and then host Word inside of that but I recommend against it.

There are commercial components available that are fairly powerful. Some components even mimic VS.net IDE for example Syncfusion edit component. Search around on google.

DataSet and Date in PostgreSQL

sanfacio7-Jun-05 5:40

I everybody !

I have a little application to manage cutomers, it works under windows. I use the .Net SDK 1.1, and Sharp Develop. My Database is in a Linux server and it is PostgreSQL 8.0. I connect to that database trough the PgSqlClient .dll (http://pgsqlclient.sourceforge.net/).

Mi big problem is that I have a field Birth Date in mi Customers table, it is Date type, and stores the birth date of each customer. When I made an sql query to the database, it sends the following exception:

"Ticks must be between DateTime.MinValue.Ticks and DateTime.MaxValue.Ticks. Parameter name: ticks"

I don't know if it is because of the PgSqlClient or becasue of DataSet.

But this only happens when in my table I have a record with BirthDate lower than year 2000, I mean 1999 or before, if my record has a year such like 2000 or above, it doesn't raise exception.

My query is something like:

StringQuery = "SELECT CustNumber, BirthDate, PIN, Name FROM Customers ORDER BY CustNumber";

and when I don't select the field BirthDate, it works perfect.

I have been searching in many forums about "ticks", but no solution yet. If someone could help, thanks a lot.

By now, thanks a lot for your attention, I hope you have a great day.

Note: Sorry for the little bad english :P

Visual Studio Debugger

I am debugging a large C# program in VS 2003. When an unhandled exception occurs I receive the usual message box, but then when I dismiss the message box the debugger ALWAYS leaves me at the code

static void Main() <br />
{<br />
    Application.Run(new MainForm());<br />
}

I am used to it leaving me at the line in the program where the exception occurred. Did I accidently change a debugger setting or something? I really would like it to leave me at the line where the error occurred.

Thanks!

Mark

No, this is usually what the debugger will do if an exception occurred in non-user code (for example, in unmanaged code). Look at the stack trace in Visual Studio, the last call you'll see is most likely a call into native code.

How to request page if server demands SCRIPTING abitlity

delemur7-Jun-05 4:57

Hello
I run request (with my .NET C# application):

HttpWebRequest request = (HttpWebRequest)WebRequest.Create(url);<br />
   request.UserAgent = "Mozilla/4.0";<br />
   ...<br />
   WebResponse response = request.GetResponse();

then I read the response

Stream ReceiveStream = response.GetResponseStream();<br />
   ...<br />
   String ResponseHTML = sr.ReadToEnd();

I get a page with message 'Please activate scripting'

But when I request this page with IE - I get right (wanted) page. If I disable the property 'Run script' in browser and then request the page I receive the page 'Please activate scripting'.

How to cheat the server to get wanted page with my application?

Thanks

Process + CMD Issue

For executing cmd commands I'm using:

System.Diagnostics.Process.Start("cmd", "/c net stop messenger");

1. How to hide the popping up window from the cmd shell?
2. How to get the stream if the command executed successfully?

To launch a process without a window:

System.Diagnostics.ProcessStartInfo info = new ProcessStartInfo("cmd", "/c net stop messenger");
info.CreateNoWindow = true;

Process process = new Process();
process.StartInfo = info;
process.Start();

To get the output stream, use process.StandardOutput, which returns a StreamReader.

Thank you very much, that will help me a lot!

The windows does still appear!

And how to get that stream?

this doesn't work:
System.Diagnostics.ProcessStartInfo info = new ProcessStartInfo("CMD.exe", "/C net stop messenger");
info.CreateNoWindow = true;

Process process = new Process();
process.StartInfo = info;
process.Start();

StreamReader s = process.StandardOutput;
MessageBox.Show(s.ReadToEnd());

System.Diagnostics.ProcessStartInfo info = new System.Diagnostics.ProcessStartInfo("cmd.exe", @"/c dir D:\");
			info.UseShellExecute = false;
			info.CreateNoWindow = true;
			info.RedirectStandardOutput = true;

			System.Diagnostics.Process proc = new System.Diagnostics.Process();
			proc.StartInfo = info;
			proc.Start();
			StreamReader reader = proc.StandardOutput;
			proc.WaitForExit();
			
			Console.WriteLine(reader.ReadToEnd());

This works fine for me Smile | :)

If you want to change it only for the current sol. ,so copy these projects to another directory that is not shared by others and rename it throught this directory.

To get to objects in other namespaces, make sure those objects/classes are in the same project as the one you're building, or if they're in a different project, add a reference to the project you want to access. Then it's just a matter of MyNamespace.SomeObject

For a Windows Forms app, in your form class, override ProcessCmdKey and watch for a key press. When pressed, create a new Form and call ShowDialog() on it.

As the other poster said, look into Windows hooks, there's an article here[^] with an example. Using hooks, you can listen for all keyboard activity on the system.
