As mentioned, "you recurse through the children using the Nodes property". The Nodes property is on TreeView class and on the TreeNode class (which is used to recurse into subnodes).

There are many ways you can do this. One way is to handle the TextBox.Validating event (inherited from Control) of the DataGridTextBoxColumn.TextBox property, which gets the TextBox that is hosted when the cell is in edit mode. If you wanted to validate input as they type, handle the KeyDown event of the TextBox as well.

Setting AutoArrange to false and setting ListView.Alignment to ListViewAlignment.Default only takes effect if the ListView.View is set to View.LargeIcon or View.SmallIcon. Is this the case as well?

You can use either the SDK for the WebCam, obtained from the manufacturer's website (http://developer.logitech.com[^] for Logitech cams) or try the Windows Image Acquisition API, docs are found here[^].

How do you do anything useful with the Scroll event for a DataGrid? I ned to take some action depending on which portion of the grid is visible, but there's no FirstVisibleRow property, although there is a FirstVisibleColumn.
I could do this with the scroll bars in an MFC ScrollView, but I can't see it in .NET.
|
|
|
|

Oh what, you're saying their example for the Scroll event in the SDK docs that pops up a MessageBox every time you scroll isn't practical?! 
You could simulate a FirstVisibleRow of sorts (if you're extending DataGrid, it would definitely make a good read-only property) by calling DataGrid.HitTest with coordinates that would always be in the upper-left corner, like 1, 1.

But the Scroll event has a EventArgs not a MouseEventArgs so I can't do a hit test can I? If I could find the position of the slider (relative to top & bottom of the scrollbar) that would be enough.
|
|

|

For one, you can get the mouse position in screen coordinates at any time from the static Control.MousePosition property, but you didn't read my reply so this really doens't make a difference.
When you scroll, obviously a new row is displayed at the top of the DataGrid, right? All you need to do is call HitTest with the coordinates 1, 1 (or new Point(1, 1) and that will get you the row currently at the top of the DataGrid's view. This is a very simple workaround.
If you want the slider position, simply P/Invoke the SendMessage API and send the SBM_GETPOS message to the DataGrid control using its Handle property (the HWND for the control). This will get you a value of between 0 and 100, so you'll need to take the row height into account and calculate everything, but the workaround above is so much simpler and doesn't require you to P/Invoke anything (making your code more portable).

I did read your reply but didn't know that HitTest could be used for anything other than a mouse position - that's what the help for HitTest suggests.
But I'm still not getting there...
DataGrid.HitTestInfo hti = valueGrid.HitTest(1,1);<br />
int row = hti.Row;<br />
if (row >=0)<br />
{.......<br />
but row always gives -1 no matter where the scroll position is.
I've also tried
DataGrid.HitTestInfo hti = valueGrid.HitTest(valueGrid.Location);
but no joy, and even tried checking the point in the middle of the top left cell, but again always row = -1.
Obviously I'm missing something very obvious!

How can i Open OUTLOOK EXPRESS from another Application .Example Suppose I have a Button upon a form in C#.net and I want that I will click upon the button a Outlook should be opened .
Thanks

This is very simple!
Step 1: Create an instance of an System.Diagnostics.Process Object.
Example: private System.Diagnostics.Process process1;
Step 2: Set the properties of process1.
The following property is important: StartInfo.FileName
Example: this.process1.StartInfo.FileName = "[path]";
Step 3: Start the process.
To start the process you call the method Start().
Example: this.process1.Start();
If you need the complete code sample let me know.
Good luck!

You can shorten this procedure by using the static Start method.
Process.Start(path, arguments);
The parameter arguments is optional, so the method call will look like this.
Process.Start(path);
|
|
|
|
|
Try this one (replace the address to the actual address)
Process.Start("mailto:someone@hotmail.com");

Generate the assembly with a different name, like Interop.SHDocVw.dll, which is what VS.NET would call it if you did imported the typelib in the shdocvw.dll library by adding a COM references in the Add Reference dialog.
If you're using tlbimp.exe, use command line switches like this:
tlbimp /out:Interop.SHDocVw.dll %WINDIR%\System32\shdocvw.dll Type the following for more information about the switches available for tlbimp.exe:
tlbimp /? You should also consider signing this and keeping it in a global directory that's easy to reference. If you do sign it, you can install it in the GAC. Believe me, this is a common assembly in many applications, except that everyone signs it with a different key, if they sign it at all (production code should always be signed to help protect the integrity of the product, not to mention it's so easy there's no excuse not to).
