Use this regular expression:

(?<url>(mailto\:|(news|(ht|f)tp(s?))\://){1}\S+)<br />

The one I gave in the previous reply works fine on my machine, remember to write the string in code as @"regex" rather than "regex" since C# will try and escape the \ characters.

StringPointer Problem with TVM_GETITEM! [modified]

Hello!
[modified] Thanx to OrlandoCurioso!
I have tried to use a SendMessage with TVM_GETITEM with a TVITEM struct... but I got no result at all =/
Here is the code(piece):

[StructLayout(LayoutKind.Sequential, CharSet = CharSet.Auto)]
public struct TVITEM
{
public int mask;
public IntPtr hItem;
public int state;
public int stateMask;
[MarshalAs(UnmanagedType.LPStr)]
public string pszText; // string pointer
public int cchTextMax;
public int iImage;
public int iSelectedImage;
public int cChildren;
public IntPtr lParam;
}

StringBuilder sb = new StringBuilder(256);
TVITEM tvItem = new TVITEM();
tvItem.hItem = (IntPtr)Int32.Parse(textBox1.Text);
tvItem.cchTextMax = 256;
tvItem.pszText = sb.ToString();
tvItem.mask = TVIF_TEXT; // TVIF_TEXT = 0x0001;
IntPtr j = SendMessage(TreeHandle, (int)TV_Messages.TVM_GETITEM, (int)0, ref tvItem);
MessageBox.Show(j.ToString());

I´m still having some troubles... I think my only problem now is with the the String Pointer... If I can make it work... I can Retrive my item´s name from the TreeView... and it´s done!

Thanks!

You use the TV_INSERTSTRUCT declare.
This is correct:

[StructLayout(LayoutKind.Sequential,
CharSet = CharSet.Auto)]
public struct TVITEM
{
public int mask;
public IntPtr hItem;
public int state;
public int stateMask;
public IntPtr pszText;
public int cchTextMax;
public int iImage;
public int iSelectedImage;
public int cChildren;
public IntPtr lParam;
}

Take a look at DShowNET[^] this is a wrapper around DirectShow and you can enumerate devices using that wrapper, albeit in quite a round-a-bout way.

Datagridview row display

Is there any method I can use to jump to a particular row in a datagridview so that that row is highlighted and is displayed as if the 1st row (those rows before it would be scrolled up to be viewed)?

Tryed all my best but still didn't find any method or way that bring up the specific row in the DataGridView. Well, if you want to select a specific row, you can do it as follows:

<br />
DataGridView1.ClearSelection();<br />
DataGridView1.Rows[index].Selected=true;<br />

where index is an integer variable holding a valid value, or instead of it you can pass an integer value. The ClearSelection method will clear the previous selected row(s).

Best Regards.

Thanks Office Lineman
Its solved part of my problem too.
now the code would be like that:

DataGridView1.ClearSelection();<br />
DataGridView1.Rows[index].Selected=true;<br />
DataGridView1.FirsDisplayedScrollingRowIndex=index;

Thanks and Best Regards.

Remote capture SharePoint?

Lane Yu8-Jun-06 17:16

Lane Yu

8-Jun-06 17:16

Our team is developing a product which can capture documents and other data from SharePoint sites.
So far we know we can do this with SharePoint SDK, but our program has to be installed on the SharePoint server, or at least in the Server Farm.
Thus it's very inconvenient to deploy the product.
We would like to know if there's a way to capture the data remotely. That is, can we capture all the SharePoint servers from a central server?
BTW, is it possible that we can know which machine has SharePoint server installed by scanning the AD?

Thanks a lot.
