how can i convert this code to c#
especially the ReDim Preserve...
Public Function Get_Key(ByVal KeyPath As String, ByVal KeyName As String, ByVal host As String) As String
Dim RKey As Byte()
Dim ilByte As Integer
Try
Dim Key As Byte() = Get_Reg(KeyPath, KeyName, host)
ReDim Preserve RKey(14)
For ilByte = 52 To 66
RKey(ilByte - 52) = Key(ilByte)
Next ilByte
Catch ex As Exception
Return ""
Exit Function
End Try
Return ""
End Function

Our Instant C# VB to C# converter produces:
public string Get_Key(string KeyPath, string KeyName, string host)
{
byte[] RKey = null;
int ilByte = 0;
try
{
byte[] Key = Get_Reg(KeyPath, KeyName, host);
byte[] tempReDim1 = new byte[15];
if (RKey != null)
System.Array.Copy(RKey, tempReDim1, System.Math.Min(RKey.Length, tempReDim1.Length));
RKey = tempReDim1;
for (ilByte = 52; ilByte <= 66; ilByte++)
{
RKey[ilByte - 52] = Key[ilByte];
}
}
catch (Exception ex)
{
return "";
//yes - silly, but this is what you're original code does
//(the statement is never executed)
return null;
}
return "";
}

I have a DataGridView control on a form which is bound to a class that is derived from CollectionBase and implements IBindingList. This works okay except that the sorting acts really strangely in certain situations. To sort my class I implement IBindingList.ApplySort and in the method I use CollectionBase.InnerList.Sort and pass it an instance of a class that implements IComparer to sort the data objects in my list. The implementation of the IComparer.Compare method is relatively straightforward:
object a = MyType.GetProperty(PropertyName).GetValue(x, null);
object b = MyType.GetProperty(PropertyName).GetValue(y, null);
if (a != null && b == null)
return 1;
if (a == null && b != null)
return -1;
if (a == null && b == null)
return 0;
return ((IComparable)a).CompareTo(b);
Now this sort of works okay. For example, if my data object has properties a, b, and c which are displayed on the DataGridView like this:
a b c
100 1 1
90 2 1
80 3 1
70 4 1
60 5 1
50 6 1
40 7 1
And I click on the header for row a I get this:
a b c
40 7 1
50 6 1
60 5 1
70 4 1
90 3 1
90 2 1
100 1 1
And if I click it again I get back to the original. So far so good. If I click on column b, I get the expected behavor too. However, if I click on column c (where all the values are the same) I get this:
a b c
60 5 1
50 6 1
40 7 1
70 4 1
100 1 1
90 2 1
80 3 1
Clicking a second time gets me to the second table above. Clicking a third times gives me this:
a b c
80 3 1
90 2 1
100 1 1
70 4 1
40 7 1
50 6 1
60 5 1
And finally, clicking a fourth time gets be back to the original order.
Does anybody have any idea what is going on here and how I can avoid it? This doesn't seem to ever happen if I use a DataTable as a data source.

I am curious as to what the code is to put an application in the Task Bar like Windows Media does when you minimize it.
The only other application I've seen do this was Norton Antivirus 2006.
I did my googles to try and find out the api calls for this but came up empty.
Anyone have a clue as to how this is done?

Excellent, just what I was looking for.
Thank you very much.

It appears that a ToolstripLabel control (in a ToolStrip) won't render its text unless the control is wide enough to completely display it. This occurs even if the text contains embedded spaces.
Is there any way to relax this restriction?
Thanks,

All the strings are the results of the HTTP "get" method used in a web form. See the W3C recommendations on form submissions:
http://www.w3.org/TR/REC-html40/interact/forms.html#h-17.13[^]
Basically you'd need to extract everything after the ?, then break the string up using the & as a delimiter and finally you end up with a set of properties and their values seperated by = signs.
So your first example should be read as
hl=en
q=microsoft+apple
meta=
obviously the q part is the actual query which was for "microsoft AND apple"

You'd have to rewrite your app to deal with it.

It is easy to add a messageFilter to an application, such as Application.AddMessageFilter. But if i use Java to call this COM component, is it possible to bond an IMessageFilter to a COM component?
Thanks

I want to combine Windows Media Player and Quicktime to be avalible in one Form.
But how do I do this?
Is there any article (on CP) which explain that?

I have a strange problem. Here is what I try to achieve:
Have a background thread performing work, and sending events so the form can update controls as work progresses. To do this, i use Delegate.BeginInvoke and its companion Delegate.EndInvoke.
This works very well, except when I added another event (still works for other events, though). This event is special as the it inform the Form that an exception has occured. This event has information to display to the user as how to fix the problem.
The EventArgs has a member similar to CancelEventArgs, to tell the event raiser whether the execution of the task should be retried or cancelled. To achieve this, the event handler displays a dialog box asking the user to fix the problem. This form has buttons to ask the user if the problem is fixed or not, thus indicating the worker thread to retry or not.
I have tried to display the secondary for to the user using 2 ways (none worked):
1- Calling Form.ShowDialog directly from the event handler.
2- Calling Form.Invoke from the event handler to have the secondary form instantiated on the same thread as the form one.
None work, the code stops at the Showdialog call, the form never appears, and the worker thread finishes at the event raising line (Delegate.EndInvoke is called).

I tried something similar using an empty form, and it works fine. Are you sure your secondary isn't coming up behind your other windows? 
I recommend you investigate the problem by simplifying it. Create a small app and focus on duplicating just the parts that you think are not working as expected.

Sounds like the call to ShowDialog is on the wrong thread. Have you checked that with InvokeRequired?
As a side note, I highly recommend System.ComponentModel.BackgroundWorker for what you're doing. It handles exceptions for you, passing the exception as an object to an event raised on the UI thread. No manual Invoke/BeginInvoke required.

Unfortunately, I must use .NET 1.1. I will try the InvokeRequired.

tx, interesting. Btw, the problem is fixed, I did set the Form.Enabled to false (typo in code, was supposed to be for anothe control).

Form.Enabled was set to false. A mistake made selecting wrong item in Intellisense

I have an array (List<t>) containing tens of thousands of items. I need to maintain copies of the array, sorted in a few different ways. I'm working on Windows Mobile so memory is a constraint. To minimize memory requirements, in C++, I can have arrays of pointers to the first array (T*[]). I understand I can do this in C# as well, but the code is unsafe. Is there a better way of doing this in C#
